_Author's note: I received an e-mail requesting that I write a story about
aliens taking over humans and creating insatiable sexual desires. The person
requesting this story had read another story on Literotica entitled Hosts. He
was disappointed that the author of Hosts did not write any more chapters
after the first submission, which is why he asked me to write about this
topic. It is my first venture into this story category so let me know what you

CHAPTER 01 - THE INTERNATIONAL SPACE STATION  
  
Aaron Peters had just re-entered the space station after making a routine
maintenance check of the exterior. The space shuttle would be arriving in week
with the replacement crew and to take Aaron and his fellow astronauts back to
earth. Aaron's exterior inspection was to verify that the space station did
not need any external repairs or parts before the space shuttle launch. He
never noticed the alien visitor that had attached itself to his space suit.  
  
Aaron stripped off his space suit in the sterilization area and cleansed his
body before putting his on his in flight uniform. As he cleansed himself he
thought how his life had changed aboard the space station. Aaron and Captain
Carl Roberts had become very close; in fact they had become lovers. Aaron
still remembered the first time when Carl had given himself to Aaron both
orally and anally. Aaron also remembered vividly the first time that he took
Carl in his mouth and the pain he experienced when he lost his anal virginity
to Carl.  
  
Aaron had never had a male encounter before Carl and he still did not think of
himself as gay. Maybe it was because his fellow astronauts Rachel Cummings and
Dr. Sam Leonard had sex together every chance they had. They were like rabbits
those two and Aaron often wished that he was in Sam's place and that he was
fucking Rachel. Aaron was in a constant state of horniness thinking about
Rachel and Sam which is why he probably was receptive to Carl's advances. Carl
however was a master of seduction and he had proved to be an excellent lover.  
  
Aaron was deep in thought when the alien stowaway left the spacesuit and
adhered itself to Aaron's body. The alien had been blown toward the space
station when its planet exploded scattering all its inhabitants all over
space. The alien moved undetected along Aaron's body searching for an
accessible orifice to enter the human form. The alien was in need of
nourishment and sought to become a parasite in a host body. Once inside the
host the alien would become capable of producing more alien bodies.  
  
The alien located an opening in Aaron's right ear and entered it rapidly.
Aaron felt the intrusion and rubbed his ear quickly but the alien had already
wormed its way inside. Once inside the alien moved through Aaron's body and
located the place where it could nourish itself. Aaron had felt a sharp pain
and then some discomfort in his ear. He decided that he would have Sam look at
it later. Aaron put on his Lycra tight fitting uniform and entered the main
area of the space station. His ear was starting to feel better but there was
something strange happening to him.  
  
The alien was releasing a substance in Aaron's body that had the effect of a
sexual stimulant. All of a sudden Aaron was obsessed about sex and he had a
throbbing erection. Aaron's cock felt bigger and stiffer than ever. Aaron
looked down at his cock straining to get out of his uniform. The outline of
his cock was clearly visible and it looked like he had a pipe in his pants.
Aaron was still worried about his ear so he decided to have Sam check him out
right then. Aaron still had no explanation for his body's recent sexual
reaction.  
  
Aaron entered the medical area and he stopped in his tracks. Rachel was on the
examination table on her back and Sam was between her legs. They were both
naked and Sam was drilling Rachel's pussy with his rock hard cock. Aaron
watched the attractive couple fucking on the exam table and then he felt his
own cock straining against the fabric of his pants. Aaron reached in his
pants, fished his cock out and stared at his member in disbelief. His cock had
grown to at least 10" long and 6" around. How was that possible? It had always
been average at 6" long and about 5" around.  
  
The alien had taken over Aaron's body and looked through Aaron's eyes at the
other two humans engaged in sex. The alien had Aaron focus on Sam's asshole
and Aaron stared at it as he watched Sam fuck Rachel senseless. Aaron moved
toward the couple on the exam table and he picked up a tube of lubricant as he
approached them. Aaron greased up his cock thoroughly and then under the
control of the alien, Aaron leaped up on the table behind Sam and buried his
cock in Sam's asshole.  
  
Sam screamed out loud as his asshole was stretched beyond belief. The pain was
excruciating and tears welled up in Sam's eyes when he felt the huge cock
enter his rectum. Sam tried desperately to dislodge Aaron but Aaron under
alien control was too strong for Sam. Aaron held Sam in a vice like grip as he
drilled Sam's ass taking the doctor's anal virginity.  
  
Aaron felt a tremendous pressure in his balls and then he ejaculated into
Sam's ass. Aaron grunted and Sam cried out as Aaron flooded Sam's rectum.
Aaron seemed to cum for several minutes as he unleashed a torrent of cum into
Sam's asshole. Unbeknown to Sam a number an alien body entered Sam's rectum
and made its way into Sam's body. Sam was still in shock from being fucked in
the ass and he felt as if a fire hose had been shoved in it. Then a strange
feeling came over Sam as he felt Rachel's pussy tighten around his cock.
However it wasn't Rachel's pussy getting tighter it was his cock getting
longer and thicker.  
  
"Oh Sam, what's happening? Your cock is growing in my pussy. I feel so full.
It feels so good. Fuck me Sam keep fucking me!" Rachel pleaded.  
  
Rachel then noticed Aaron behind Sam but she didn't care at that point. "Fuck
me Sam, fuck me Aaron, fuck me both of you," she cried out.  
  
Sam began to pound Rachel's pussy and in doing so he impaled his ass on
Aaron's cock again. Aaron remained still and let Sam do all the work this
time. As Sam thrust into Rachel, Aaron's cock slid part way out of Sam's ass.
Then when Sam withdrew slightly from Rachel's pussy he impaled his as on
Aaron's cock. Sam then felt his balls tighten just before he ejaculated into
Rachel's pussy. Sam filled Rachel's pussy with more cum than he ever had and
Rachel's eyes widen in surprise as her pussy was flooded with the male seed.  
  
Sam stopped moving momentarily but Aaron picked up the pace and fucked Sam's
ass again. As Aaron was fucking Sam, Rachel felt a strange aura take over her
body as an alien form had made its way into her body. Her tits and nipples
ached and she realized that her breasts were getting bibber and the nipples
were getting longer. Rachel's pussy was on fire and she screamed out for Sam
to fuck her.  
  
The three of them became insatiable as the aliens controlled their bodies and
they felt as if they could fuck and cum forever. Sam begged Aaron to give his
ass a break so Aaron pulled out of the doctor's ass. Aaron stared at his cock,
which looked huge and menacing, as he decided what to do next. Aaron then had
Sam rollover on the table keeping his cock in Rachel's pussy. Then Aaron
greased his cock again and this time he plunged it into Rachel's asshole.  
  
Rachel screamed as the searing pain ripped through her. However the pain was
brief and then Rachel yelled for both of them to fuck her. Sam drilled her
pussy as Aaron drilled her ass and Rachel just screamed for more. Carl heard
the commotion coming from the medical area of the space station and he decided
to investigate. Carl entered the area and he was stunned to see Rachel being
double fucked by his crew. Carl's cock got hard and he decided to get in on
the action.  
  
Carl moved in front of Aaron intending to put his cock in Aaron's mouth but
Rachel reached up and took a hold of Carl's cock and guided it into her mouth.
Carl started to protest but thought better of it and let Rachel suck his cock.
The alien in Rachel's body took over and Rachel took her mouth off of Carl's
cock. She then reached up and pulled Carl's face to hers and kissed him deeply
shoving her tongue into his mouth. Carl, repulsed by the female kiss, tried to
pull away but Rachel was too strong. Carl felt Rachel's oral fluids enter his
mouth and she drove her tongue into him forcing him to swallow.  
  
Rachel released Carl and he stepped back and stared at her with contempt. Then
just as it had happened to Aaron and Sam, Carl felt his body change. He
suddenly felt stronger and he was astonished as his cock grew in size before
his eyes. Carl watched as his cock grew to at least 10" in length and swelled
to 6"around. He could not explain why his body was changing but he was
thrilled with the increased size of his cock. Rachel then pulled Carl's cock
back to her mouth and Carl at this point did not care who was sucking him off,
male or female. Carl felt his bloated balls tighten and then he ejaculated
into Rachel's mouth. Rachel gulped down every drop of Carl's cum and then she
felt Aaron and Sam cum in her asshole and pussy. Rachel went wild and she kept
cumming and cumming as if there were no end to it.  
  
The four of them continued to have sex for hours with Rachel as the focal
figure. The three men took turns in her pussy, mouth and ass. When they were
finally done they looked at each other curiously and they then realized that
they would never be the same again. Each of the men had cocks that were
identical in length and girth. They were all fitter and stronger and had an
insatiable sexual appetite. Rachel's breast had developed to a full 36C and
they were firm with extended nipples.  
  
For the next several days before the space shuttle arrived with the
replacement crew, the four of them had sex for hours upon hours each day. They
hardly ever wore their uniforms and they remained naked most of the time.
Finally the shuttle arrived to take them back to earth and the replacement
crew was impressed with the physical condition and appearance of Aaron, Sam,
Carl and Rachel. Of course the aliens inside the host bodies would travel to
earth and seek to populate more humans which they would do using the
astronauts as sex objects. A few alien bodies remained at the space station to
eventually take over the replacement crew.  
  
CHAPTER 02 - ASTRONAUTS ARE DEBRIEFED AND RETURNED TO DUTY  
  
The space shuttle returned to earth and it was all the astronauts could do to
refrain themselves from some form of sex while on the shuttle. The alien
bodies within their hosts sensed the astronauts struggle with morality and
actually helped them maintain a professional image.  
  
Each astronaut was debriefed by a NASA official and the officials were very
impressed with the crew's fitness. They all seemed stronger and trimmer since
they began the mission. After a few days of debriefing the astronauts were
allowed to return to their normal lives although nothing would ever be normal
about their lives from her on.  
  
Before they reunited with their families and friends the astronauts spent one
more night at the NASA building with sleeping accommodations. After dinner
that night they met in Rachel's room where they unleashed days of sexual
frustration. Within minutes of entering her room the three men were fondling
Rachel's body. Rachel squirmed with desire as they ran their hands all over
her. They groped her breasts and squeezed her ass. Then they began to remove
her clothing. First her blouse and bra came off and a set of hands rubbed her
tits. Rachel reached for the hands grabbing her tits and then she felt her
pants being lowered.  
  
Her pants were tugged down her legs. It was a tight fit as it was pulled over
her buttocks and down her legs. Rachel almost fell with the pants around her
ankles but Carl held her from behind and his hands covered her breasts. Aaron
pulled the pants off of her legs leaving Rachel dressed in only her panties.
She looked very sexy like that and the men felt their erections pushing
through their pants.  
  
Aaron was now sucking on Rachel's tits and teasing her nipples with his teeth.
Rachel faked fighting it but she was getting excited and she knew her pussy
was wet. Rachel then felt Carl behind her and he pulled her panties down over
the cheeks of her ass. Her pussy was still covered but her buttocks were bare.
Carl then massaged her fleshy ass cheeks emitting a moan from Rachel. Sam then
took hold of her panties and peeled them down to her knees baring her neatly
trimmed pussy. Sam ran his fingers over her vulva causing Rachel to groan. She
knew her pussy was dripping wet with desire and that Sam would be able to
sense her state of arousal. Sam then removed Rachel's panties from her body
leaving her standing naked except for the blouse around her wrists.  
  
Rachel was now completely naked in front of the three men. Carl moved to one
side of her body and Aaron moved to the other side. Both men unfastened their
pants and pushed them along with their underwear to their knees. Their
impressive hard cocks sprung lose and stood out from their bodies. Carl
grabbed one of Rachel's buttocks with his right hand and one of her breasts
with his other hand. Aaron on the other side of her body grabbed one buttock
with his left hand and a breast with his right hand. The two men fondled and
squeezed the big tits and fleshy buttocks in their hands. Rachel's hands
instinctively took a hold of both hard cocks and she stroked them slowly as
the men played with her body.  
  
Sam rubbed his hand over Rachel's vulva and then he parted her labia. He
dipped his fingers into her pussy which was now soaking wet and in dire need
of attention. Sam fingered Rachel's pussy as the others fondled her body and
she stroked the two erect cocks. Rachel felt an orgasm approaching and she
groaned when it hit her. Her body shook slightly and shivered as she reached a
mild climax. Sam felt her orgasm and smiled as he knew what to do next.  
  
"Let's take her to bed," Sam announced.  
  
Rachel was guided into the bed on her back. The three men stripped quickly and
Sam was the first one between Rachel's legs. He was rock hard and he eased his
impressive cock into Rachel's pussy. Rachel gasped when she felt the big cock
enter her and she wrapped her legs around Sam's torso.  
  
"Oh I love your new big cock," Rachel gasped.  
  
Sam started pounding away at her pussy with his big cock as he was really
turned on and close to cumming. Then his body stiffened and he ejaculated deep
into Rachel's cunt. Rachel held the astronaut tightly with her arms and legs
as he shot streams of cum into her womb. Even though Sam came quickly, Rachel
knew that she was in for a long night again with the three men. Sam pulled out
of Rachel's pussy and Carl was there immediately to take his place. Rachel
felt another big cock fill her cunt and she wrapped her legs and arms around
Carl.  
  
"Oh I like your big cock too," she gasped again.  
  
Carl fucked Rachel with rapid strokes as he too would not last long. His body
soon stiffened and then he filled Rachel's cunt with his load. Her pussy was
overflowing with cum and it began to trickle out of her. As soon as Carl
pulled out of her Aaron was in her and he too fucked her hard and fast before
shooting his load into her. Rachel also orgasmed and she wrapped her arms and
legs around Aaron and squeezed his body as she climaxed. Aaron felt her cunt
muscles working his cock as she came. Aaron let Rachel relax before he pulled
his cock from her pussy. The three men watched as cum trickled out of Rachel's
cunt and coated her inner thighs.  
  
All three men were still erect and their big cocks dangled in front of them.
Rachel stared at the impressive cocks that were now above their former average
size. She guessed them to be in the range of 10-11 inches long and at least 6
inches around. Rachel liked their new cocks at this size. Sam crawled back
between her legs and he slipped his cock into her cum filled cunt.  
  
Rachel knew that Sam would last longer this time and that she would probably
orgasm again before he came. Carl knelt along side Rachel's head on one side
and offered his cock to her mouth. Rachel turned her head to one side and took
the big dick in her mouth. Aaron moved to the other side of her head and
Rachel took turns sucking on Aaron's and Carl's cocks as Sam fucked her.
Rachel had multiple orgasms before Sam came again and her pussy was cum
drenched with commingled juices. Then it was Carl's turn to fuck her again and
Sam had her suck his cock clean of their combined juices.  
  
Rachel sucked on Aaron's cock and Sam's cock as Carl fucked her silly. Rachel
had more orgasms and she felt weak and lifeless by the time Carl fired a
barrage of cum into her pussy again. Then it was Aaron's turn even though
Rachel had nothing left. She lay almost lifeless as Aaron fucked her until he
came again. Sam then searched through her purse and located a bottle of hand
lotion.  
  
The lifeless body of Rachel was then rolled over and her hips were pulled up
so that her big ass stuck up in the air. Sam got behind Rachel and he began to
fondle her ass and tease her nether hole. At the same time Carl got in front
of Rachel and fed his cock to her mouth. Rachel sucked on the big dick as Sam
fingered her asshole and pussy at the same time. He had put an ample amount of
lotion in her asshole and his finger moved around easily. Satisfied that she
was ready, Sam put lotion on his cock, spit in his hand and stroked his cock
making it very slick. He knelt behind Rachel and eased his cock into her
asshole. Rachel gasped on Carl's cock when she felt the big cock worm its way
onto her ass.  
  
Rachel had been butt fucked plenty of times since she lost her anal virginity
on the space station so there was no pain for her just that familiar sense of
fullness. Sam fucked her slowly as she sucked on Carl's cock. Aaron moved
along side her and he played with her big tits as they hung down toward the
bed. Sam tried to prolong fucking her ass as he loved watching his big cock
slide in and out of her anal passage. He squeezed her fleshy buttocks as he
fucked her ass and he like to see them jiggle when his thighs slapped against
them. Rachel knew that Sam intended to cum in her ass and she loved the wicked
feeling of cum shooting into her rectum.  
  
Rachel felt Carl's cock pulsate in her mouth and she sensed that he would cum
before Sam came. Carl held Rachel's head gently in his hands as he erupted in
her mouth. Even though it was his third load there was still plenty of it.
Rachel gulped and swallowed as quickly as she could as jet after jet shot into
her mouth. Carl's ejaculation finally subsided and Rachel sucked on his cock
gently milking the remaining cum from his shaft. Carl was thrilled that she
swallowed his load just as his gay lovers would.  
  
Rachel then felt the first jolt of cum shoot deep into her rectum as Sam began
to ejaculate. He fired five or six streams into her anal canal and then the
barrage stopped. Rachel felt the fullness in her ass and she used her anal
muscles to squeeze every last drop of cum from Sam's cock. His cock eventually
softened and slipped from her asshole with an audible pop and a trail of semen
oozing out of her anus. Rachel relaxed for a minute and she felt Sam's cum
trickle down her inner thighs.  

Rachel did not relax long though as Aaron was behind Rachel and he pushed his
impressive cock into her ass. Aaron was excited to be in her ass again and he
fucked it fast and furious. Aaron too loved the way her buttocks jiggled as he
slammed into her seeking another ejaculation. Rachel was presented with Sam's
cock to suck clean as Aaron drilled her ass. Rachel sucked on Sam's soft cock
and she liked the feel of it in her mouth. Then she felt Aaron stiffen and cum
in her ass. Once again she was surprised with the force and the amount of
semen that the men generated when they ejaculated in her. Rachel instinctively
used her anal muscles to milk Aaron's cock dry before he finally slipped out
of her ass.  
  
The aliens used their powers to rejuvenate the host bodies and they were all
ready for more action even though they had all cum three times already. Rachel
allowed her body to be maneuvered into position as her pussy was guided onto
Sam's cock as he lay on his back. Then Carl shoved his lubricated cock into
her ass and Aaron pushed his cock into her mouth. Rachel allowed herself to be
used by her three colleagues and this time she was thankful to have a cock in
her pussy again. She too was horny again and her clit needed a good scraping.  
  
The three men fucked Rachel for a long time before they finally came again.
She had had multiple orgasms and she had collapsed on Sam underneath her.
Rachel had nothing left and she lay still as the three men sought their
pleasure. Her mouth just closed around Aaron's cock as he fucked her face
until he came in her mouth. Instinctively she swallowed his load. Carl was the
next to cum and he shot his wad in her ass which was filled to overflowing.
Finally Sam came in her pussy and then Rachel moved off of him and lay face
down on the bed.  
  
The aliens decided that their hosts had had enough for one night. The three
men left Rachel in bed and returned to their own rooms. Tomorrow they would
return to their families and lifestyles unaware that the aliens had even more
surprises for the crew in the days to come.  
  
THE NEXT CHAPTER  
  
Rachel returns to her husband and 18 year old son. She kisses both of them
passionately as she had not seen them in months. However unbeknown to her she
passes an alien substance on to both her husband and son. Her son watches his
mother and father engage in sex and he feels compelled to join them. Rachel's
husband in turn passes the alien substance onto his mistress and her son
passes it onto his virgin girlfriend.

THE HOMECOMING  
  
Rachel arrived home while her husband Ralph was still sat work and her 18 year
old son Ricky was in school. Rachel was anxious to see them both since it had
been months since she was home. Rachel also had that burning sensation in her
pussy and she was anxious to make love with her husband as soon as he got
home. She wondered what her husband would think of her new fit body and big
firm tits. Rachel assumed that her husband would be anxious to have sex since
Rachel had been gone so long.  
  
Ralph, however, had not been faithful while his wife was in space. He had
started and affair with his secretary and at they very moment she was on her
knees in his office sucking his cock. Ralph knew that he would have to cool it
now that his astronaut wife was back home but he loved his secretary Betty's
blow jobs, so he just had to have one more before he faced his wife.  
  
As Ralph was getting his pipes cleaned, his son Ricky was in his car making
out with his high school sweet heart Cindy. Ricky had parked down the street
from Cindy's house and they were kissing and petting before Cindy went into
her house. By the time Cindy got out of the car Ricky was ready to cum in his
pants. As he drove home his balls ached and he needed to jerk off as soon as
he got in the house. Ricky and Cindy had not had sexual intercourse yet but
they talked about it since had just turned 18 years old. They had experimented
with mutual masturbation and Ricky loved the way Cindy jerked him off. Cindy
also liked having her pussy fingered while Ricky sucked on her breasts. Ricky
could hardly wait until they took it to the next step.  
  
Ralph and Ricky arrived home about the same time and they were shocked when
they saw Rachel. Ralph could not believe how good she looked and her figure
was better than ever. Ricky stared at his mom as she had never looked hotter.
Then alien inside of Rachel stared through her eyes at the two men and
signaled Rachel to kiss them deeply.  
  
"It's so good to see you both," Rachel said happily.  
  
"It's good to see you too, you look great," Ralph replied.  
  
"Yeah mom, you look great," Ricky agreed.  
  
Rachel then embraced her husband and kissed him deeply driving her tongue into
his mouth and releasing an alien substance into his mouth. Then Rachel turned
and embraced her son and French kissed him depositing an alien form into his
mouth. Ricky was shocked at his mother's behavior but he shrugged it off
thinking that she was just so happy to see him.  
  
Ricky then excused himself and went up to his room. All of a sudden he felt
very horny and he needed to jerk off. That session with Cindy had a bigger
effect on him then he thought. Rachel took Ralph by the hand and led him to
their bedroom and within minutes they were naked in bed together. Ralph felt a
strange feeling run through his body and his cock ached as it began to
stiffen. Ralph stared at his wife's hot body and firm big tits. It looked like
she had gotten a boob job but he knew that was not possible. Something must
have happened in space that changed her body for the better.  
  
"I need you Ralph," Rachel cooed as she opened her legs to welcome him into
her.  
  
"I missed you baby," Ralph lied thinking about his secretary as he pushed his
cock into his wife's pussy.  
  
Ralph remembered how his wife only liked to fuck missionary style. She would
ride him sometimes or let him fuck her doggy style but she never took it in
the ass or sucked his cock. That's what he liked about Betty as she did it
all. Of course Ralph had no idea how the time in space had changed his wife
but he was about to find out.  
  
Rachel had been dying to get a cock in her since the last time with her fellow
astronauts. Now finally her husband was in her but she found that she missed
the big cocks of her colleagues. Then she felt her husband's cock begin to
swell in her pussy and rub against her clit. Ralph drove into her as he felt
her pussy tighten around his cock. He never knew that she could be so tight.
Ralph had no idea that the alien body had located itself in him and was
causing his body to change. The two of them raced toward their orgasms and
Ralph felt his ball sac tighten. He drilled his wife and unleashed a torrent
of cum in her pussy. He couldn't believe that he could cum that much
particularly after cumming in Betty's mouth earlier that day. What was even
more remarkable was that he stayed hard and continued to fuck Rachel until she
came and flooded her pussy with her female nectar. Ralph's cock was soaking in
a pool of co-mingled love juices.  
  
Ricky had heard the noise in his parent's bedroom while he was jerking on his
cock thinking of his girlfriend Cindy. As the alien form took over Ricky's
body it directed Ricky to his parent's bedroom. Ricky stood at their door and
watched his parents make love except that it was more raw sex than love. When
his dad pulled out of his mother and rolled over on his back, Ricky stared at
his father's huge cock. Ricky couldn't believe it as he knew that his father
had a smaller cock than that. How could it look so large now? Then Ricky
noticed his own cock growing in length and girth to a point where his hand
could not wrap around it any longer.  
  
Rachel mounted her husband's big dick and lowered her pussy onto it. Then they
began to fuck like animals again. Ricky watched his parents fucking and then
he decided that he just had to join in. He walked in the bedroom and with the
alien's guidance he got on the bed behind his mother. He stared at her asshole
as she humped her husband's cock and then Ricky scooped up her juices and
rubbed them on his cock. Ricky used his mother's pussy juice to lubricate his
cock and then her asshole.  
  
Rachel felt her son's finger probe her anus and she looked over her shoulder
and spoke, "That's it Ricky get my asshole wet. Get it ready for your cock."  
  
Ralph couldn't believe his ears when he heard his wife. She was asking her son
to fuck her in the ass. Ricky used his saliva along with her juices to get his
cock slippery and then he eased it into her asshole. Rachel groaned with
pleasure as the big cock slid into her rectum. Ralph and Ricky could feel each
other's cocks through the thin membrane in Rachel's body which was an added
turn on for them. The two of them established a rhythm and they skewered
Rachel's body.  
  
Ricky was the first to cum this time and he flooded his mother's ass with his
load. Ricky never in a million years would have thought that he would lose his
virginity to his mother. He also would have never expected to fuck any girl in
the ass much less his mother. Ricky stayed hard and kept pounding his mother's
ass until his dad came again and his mother screamed with another orgasm.  
  
The three of them stayed in bed for hours sucking and fucking. They changed
positions each time with the husband and son taking turns in Rachel's pussy,
mouth and ass. Ralph couldn't believe the display of raw sex from his wife. He
was also shocked that his son had taken her ass before he did. Hours later
they finally stopped having sex and collapsed on the bed. The three of them
lay there contemplating what had happened and how it would change their lives
forever. The alien's inside their human hosts were pleased with what they had
accomplished and they looked forward to recruiting more human hosts.  
  
THE DAY AFTER AT THE OFFICE AND AT SCHOOL  
  
The next morning Rachel, Ralph and Ricky fucked like rabbits before Ralph went
to work and Ricky went to school. Rachel spent the day resting and
recollecting what had happened to her. Before the time of the space station
she had been a conservative lover even with Sam her fellow astronaut. Whatever
happened that day when Aaron and Carl joined in had changed her forever. It
was as if she didn't have any control over her body any longer. She wondered
how her fellow astronauts were doing.  
  
Betty had been waiting for Ralph to arrive at work. She was sure that he had
made love with his wife the night before and she wanted to refresh his memory
as to who was the better sex partner. Betty noticed that Ralph had a few
trivial meetings that morning so she cleared his calendar. She had worn his
favorite outfit, a mini skirt and a tight fitting blouse. Ralph always liked
to slide his hand up under her short skirt to squeezed her ass and play with
her pussy.  
  
When Ralph arrived Betty followed his into his office and closed and locked
the door. Then she walked up to him and kissed him. The alien through Ralph's
eyes studied the attractive Betty and decided that she would be a good
recruit. Betty dropped to her knees and opened Ralph's pants and pulled them
to his ankles. The she lowered his undershorts and watched in amazement as his
huge 11 inch cock leaped out.  
  
"Ralph, what happened? How is this possible?" Betty stammered as she looked at
the big cock that had replaced his average size pecker.  
  
"I don't know, just blow me," Ralph gasped.  
  
Betty stared hungrily at his huge cock and then reached out with her hand to
stroke it. She marveled at its size and wondered how she would ever handle it.
Ralph sighed as she masturbated him. She leaned forward and her tongue snaked
out and lapped at his ball sac lightly, then she gently licked up and down his
shaft. Her tongue circled his cock head as she slowly took the head of his
penis into her mouth. Her lips slid further down the shaft as she was able to
take half of his cock in her mouth drawing a moan from him. Betty began to bob
her head back and forth on his cock, sucking hard on his huge member and
testing her gag line. She was able to get about seven of his eleven inches in
her mouth. Betty slurped loudly on Ralph's dick as her soft lips glided
smoothly up and down his long cock.  
  
Ralph stood before the shapely Betty as she sucked ravenously on his oversized
cock. Her hand cupped his balls and gently caressed them as her tongue licked
at the head of his dick each time it came out of her mouth. Ralph placed his
hands on the back of her head and guided her as she gave him an incredible
blowjob. He loved the way she sucked his cock. She was so hot and he couldn't
believe his good fortune as he held her hair back to watch her pretty face and
sensuous mouth. Betty kept her eyes closed with her lips snugly wrapped around
his shaft as she bobbed back and forth. She was still incredibly turned on and
her panties were soaked.  
  
Ralph brought new excitement into her life with his renewed big cock and Betty
realized that she was addicted to it. She was so enamored with his impressive
cock; she found that she loved to suck on it. Betty was desperate to please
him and to make him cum. She loved to swallow cum. Betty wanted this to be
Ralph's best blow job ever and she put all her efforts into it even more so
than she ever had with any other lovers. It did not take long to bring Ralph
to the edge.  
  
Ralph announced that he was cumming and Betty clamped down on his cock
determined to swallow every drop of his seed. She could feel his cock jerk in
her hand as volley after volley bounced off the back of her throat. Betty
swallowed as quickly as she could and did not allow a drop to escape her
mouth. She continued to suck on his cock milking it dry of his sperm. Then
Betty took the cock from her mouth and Ralph watched as she squeezed more cum
out the end of his dick. Betty then wrapped her lips around it and sucked his
man juice dry. She nibbled on his dick head causing him to shiver and he
pushed her away. Ralph's cock stayed hard and Betty marveled at the impressive
organ before her.  
  
Of course Betty had no way of knowing that an alien substance had entered her
body and would soon take over. Betty cleaned off the top of the desk and lay
on top of it. She pulled up her short displayed her beautiful neatly trimmed
pussy to Ralph. She opened her legs and smiled at him. Ralph smiled too as it
was clear that she had removed her panties earlier.  
  
"Now do you have something for me?" she said as she opened her legs before him
hiding nothing and leaving no doubt as to her desire.  
  
Ralph stood before Betty at the end of the desk and kissed her from her knee
up her soft thighs towards her womanhood. He took in the lovely smell of her
as he kissed her smooth creamy white skin just beside her vagina. Betty was in
a state of ecstasy and her heart pounded as she watched her boss lick her. Her
cunt lips quivered as he teased them with his tongue and kissed her everywhere
she desired. Ralph's tongue probed deep into the inner walls of her pussy.  
  
Betty ran her hands over her body cupping her breasts and rolling her nipples
between her fingertips. It was strange that she felt that her bra was almost
too small for her. Her breast seemed confined all of a sudden and her nipples
ached. Ralph sucked her cunt lips into his mouth as his tongue snaked around
in her snatch. Ralph still had not made contact with her clit and Betty
desperately needed his tongue or his cock to touch her clit. She moaned in
pleasure and frustration as Ralph continued to tease her. He again wiggled his
tongue deep within her pussy before finally nudging her clit. Betty jumped as
a spark of pleasure shot through her body. Ralph slid his hands under her
curvy ass and lovingly cupped her shapely ass cheeks. He sucked her clit into
his mouth and held it between his lips as he ran his tongue over the hard
little pearl. Betty arched her back as she felt her orgasm approach.  
  
"Oh yes, oh my," she called out as the first wave rocked her body.  
  
Betty grabbed Ralph's head with both hands and pulled his face harder into her
crotch. She vigorously humped his face as his tongue danced over her super
sensitive cit. Her thighs clamped around his head and her entire body trembled
as she came again almost violently. Betty felt her pussy pulsating as she
covered Ralph's face with her female juices. Finally she collapsed back on the
desk releasing him in the process.  
  
"Oh my God," Betty moaned.  
  
Ralph got between her legs. His huge cock looked menacing as it hovered above
her hips.  
  
"Are you ready for this?" he asked smiling confidently.  
  
"Oh yes, yes please, fuck me now," Betty pleaded.  
  
Ralph held his cock and lined up the swollen head with the entrance to her
sex. He pushed forward slightly allowing her tight cunt lips to open up for
his impressive cock. He was about half way in when he pulled out and then
slowly eased back into her causing her to moan in pleasure. Ralph would push
in a little and then pull out a little slowly working his cock deeper and
deeper into her vagina. Finally his entire cock was buried in her and Betty
sighed feeling completely full almost afraid to move. This was a new sensation
for her to be this full.  
  
Ralph held himself inside her waiting for Betty to start fucking him. He
looked down at her and smiled and then she pulled him down to her and they
kissed deeply with their tongues playing with one another. Betty was ready to
be fucked and she needed his big dick to slide in and out of her and rub her
clit. She began to move and then Ralph fucked her using long slow hard
strokes. Betty locked her legs around Ralph's ass and pulled him into her. He
began to fuck her harder and faster and she felt another orgasm on its way.
She was at the mercy of his gigantic organ as it pounded her pussy.  
  
Betty was so hot and squeezed him with her tight pussy; she was really a good
fuck. Ralph fucked through her one orgasm after another before he filled her
pussy with cum. His orgasm was as intense as hers as their bodies ground
together and they moaned and groaned loudly. Betty couldn't believe how much
cum he shot into her pussy particularly since he had flooded her mouth
earlier. This was a much different Ralph from yesterday.  
  
Betty could feel his cock as it still filled her cunt. Ralph slowly moved
himself away from her body and in so doing his thick cock slipped from her
pussy. Betty felt the void in her cunt as his cock left her body and she
gasped as the coolness of the air touched her vacant pussy. Betty then could
not stand the pressure on her breast any longer so she opened her blouse and
unsnapped her bra. Both she and Ralph stared at her tits and nipples as they
both had increased in sixe. Betty was lost for words and then she felt herself
rolled over on her stomach.  
  
Ralph looked at Betty's ass and he could not resist running his hands over her
shapely cheeks. Her ass was so amazing that he felt his loins stir with
desire. He hard never seen such a perfect ass which is why he loved to fuck
it. Ralph got behind Betty and kneaded her gorgeous ass cheeks. He then began
to kiss her cheeks and run his tongue lightly in the crack of her ass. Betty
wiggled her ass feeling very wicked as he tongued and kissed her. Ralph pulled
her by the hips so that her legs were on the floor and her ass was perched
over the desk. Betty's head was still on the desktop and she turned it to one
side and let out a gasp as Ralph's tongue licked close to her asshole. Ralph
ran his tongue from her pussy to her ass causing Betty to tingle in
anticipation of what might be next.  
  
Ralph spread her ass cheeks with his hands and dipped his tongue into the
crack locating her nether hole. His tongue slowly circled her anus and she
flinched at the contact. He then pushed his tongue as far as he could into her
asshole and he found herself wanting him to fuck her up the ass. She had been
ass fucked enough in the past but this time she was worried about Ralph's
size. He continued to ass fuck her with his tongue and she was at his mercy.
Her desire grew as he worked her ass to the point that she really wanted more
in her ass.  
  
Ralph removed his tongue from her ass and ran his hard cock between her ass
cheeks as he spoke to her, "I want to fuck you in the ass Betty. Do you want
me to fuck your hot ass?"  
  
"Oh yes Ralph, but you're so big now. You must use some cream," Betty replied
to him with apprehension.  
  
Ralph took the lubricant from his desk and moved back behind her. Betty arched
her back and pointed her beautiful ass back at him. He coated her asshole with
a generous amount of cream and slid his thick finger in her hole. He took his
time preparing her ass relishing every moment. He then coated his entire cock
with the cream and placed the head at the entrance to her anus. Ralph pushed
forward and the thick cock head squeezed into her tight asshole.  
  
Betty winched in pain as her asshole was stretched wider than ever and she
gasped, "Go slow let me get used to it."  
  
Ralph withdrew his cock head and then pushed it back in this time causing more
pleasure than pain. He pushed until a couple of inches were in Betty's ass.
Betty found herself holding her breath and her body covered in goose bumps. He
was so thick that her asshole stretched to new dimensions and held his cock in
a vice like grip. Ralph slowly slid his dick in and out of her each time going
a little deeper. The pain had subsided and was replaced with a feeling of
fullness.  

"Relax and enjoy my new found cock," urged Ralph.  
  
Betty relaxed a little and then felt more of his cock slide into her asshole.
She grunted out loud as she felt fuller and than a wave of pleasure through
her body. She was convinced that Ralph had his whole cock in her now but
really he only had about half of his big dick in her. She felt so full so had
no idea that he had another five inches before he was done. Ralph kept adding
more and more of his cock to her ass. There was pain then fullness and then
pleasure each time he went deeper. Betty would tense, relax and then enjoy it.
This pattern continued until Ralph had all eleven inches buried in Betty's
ass.  
  
"Oh my God, you are so big I feel so full," cried out Betty and then, "Uh, uh,
uh oh yes, it's so good," she cried out.  
  
Ralph reached around and played with Betty's clit as he pounded her ass. Her
pussy and asshole were on fire as the big cock reached previously untouched
areas in her body. Betty was on the brink of another huge orgasm as Ralph
methodically fucked her in her tight anus with his sizeable cock. Betty's tits
ached as her nipples rubbed against the hard desktop. Betty realized that
something was happening to her as well. Her tits were bigger than normal and
her nipples were more sensitive then she could remember. Her pussy was on fire
and she had no felt so erotic. Ralph loved watching his big cock slide out of
her shapely ass and then plunge back in as his hips slapped against her curvy
ass cheeks causing them to jiggle with each thrust.  
  
As Betty came and came her entire body went into spasm. Her pussy convulsed
and clamped around Ralph's fingers coating them with her cunt juice. Betty's
asshole pulsated as he drove his big cock in and out of it. Her ass
involuntarily squeezed and released his huge member as he fucked it causing
him to finally lose it. He slid his pecker deep into her rectum as his cock
spasmed and sent a thick stream of hot cum into her channel. Ralph kept
fucking her as load after load was fired into her ass as his cock kept
twitching and spurting inside the impaled Betty.  
  
Betty had never felt so full of cum and there was no where for it to go
blocked by Ralph's swollen cock buried in her ass. He slowed his pace and
eventually stopped allowing his cock to remain buried in Betty's ass. He did
not go soft right away and he gently moved his hips pushing cum around in her
ass. Some of it trickled out and ran down over her pussy lips.  
  
Betty could not take any more fucking and she pleaded, "Please no more, I
can't take any more, please stop."  
  
Reluctantly Ralph stopped and slowly withdrew his cock from her loosened
asshole. He marveled in the sight of his enormous cock sliding out of her
shapely ass. The man seed flowed from her asshole and ran like a river down
over her pussy and between her sweet thighs. Ralph and Betty stayed in the
same position for awhile and he massaged her beautiful ass as she remained
bent over the desk with her ass perched in the air. Ralph pushed down lightly
on Betty's back causing her to accentuate her ass even more. He loved looking
at it and playing with it as she cooed. His cock remained hard and looked
menacing around Betty's asshole. It was hard to believe that a cock that size
had just fucked such a beautiful tight ass. Betty looked magnificent with her
just fucked curvy ass in the air.  
  
Ralph took out the paper towels he kept in his desk drawer and wiped off his
cock. Betty took the towels and cleaned her body of his semen. She still had
no explanation as to why Ralph could cum so much and why his cock had grown
almost overnight. When she tried to put her bra on it wouldn't fit. Her breast
size had increased to a 36C and her blouse didn't button either. Betty's skirt
was loose around her waist and she realized that she had dropped some inches.
She was lost for words but she now had the figure that she had always dreamed
of.  
  
"What's happening to us Ralph?" she asked nervously.  
  
"I don't know Betty. But it must have something to do with the space program.
Maybe they are experimenting with a new drug or something but Rachel is not
the same. I have not been the same either since we had sex together. I'll have
to speak with her this evening and see if she knows what is going on."  
  
"My clothes don't fit me anymore," Betty added.  
  
"I know. Here wear my jacket out to your car and take the rest of the day off.
Go shopping and pick up some new clothes," Ralph suggested.  
  
"Okay, I'll bring your jacket back tomorrow," Betty agreed.  
  
Betty left the office and Ralph flopped down behind his desk. He checked the
time and saw that he and Betty had been fucking for three hours. He couldn't
fathom how after cumming twice with Rachel before work how he could cum three
times with Betty. There was something very strange going on and Ralph was
convinced that NASA was behind it.  
  
While Ralph spent the morning fucking his secretary, Ricky had an interesting
day of his own. During class he kept thinking about sex. He recalled every
detail of sex with his mother and he tried to figure out what happened to his
family and why his cock got so big. He also thought of Cindy and what she
would say the next time they were together and she gave him a hand job.  
  
Ricky was so distracted that his one teacher lost her patience with his
inattentiveness and sent him to the principal's office. When Ricky stood up to
leave class he had a raging hard-on and it was very visible in his pants. Many
of the girls in class snickered when they so the outline of his cock and his
teacher was shocked by the size of it. Ricky made his way down to Principal
Hastings office. Ricky entered the office and the secretary showed him into
the Principal's office.  
  
"Ricky Cummings is here Georgette," the secretary announced.  
  
"Thank you Corrine. Please sit in the chair over there Ricky," the principal
directed.  
  
"Sure Georgette," Ricky said cockily.  
  
"It's Mrs. Hastings, Ricky. Please refer to me as Mrs. Hastings," Georgette
said firmly.  
  
Ricky smiled and half heartedly said, "Okay Mrs. Hastings it is."  
  
"That's better, now why were you sent to my office," she asked.  
  
"Because I wasn't paying attention in class, I was distracted," Ricky
answered.  
  
"I see and what distracted you?" Hastings asked.  
  
The alien in Ricky's body then took over and for the next ten minutes Ricky
explained to the principal what happened with his mother and his cock. The
principal was in shock after hearing such a rude and improper answer. However
before Georgette could speak again and scold him, Ricky shocked her by
unzipping his pants and pulling out his semi-hard cock.  
  
"Georgette all this talk has got me turned on and I need to relax. I am just
going to stroke my cock while we finish talking."  
  
Never in her career had anything like this ever happened to Georgette. No one
had ever blatantly exposed themselves to her and certainly not in her office.
Georgette looked at Ricky's impressive member as she tried to compose herself
and find the right words. Georgette now knew that Ricky's cock was indeed
bigger than any cock she had ever seen.  
  
"Ricky stop that this instant. Put your penis back in your pants and leave my
office!" Georgette said in a shaken voice.  
  
"No Georgette I won't in fact I think that we are just getting started
Georgette," Ricky said as he stood up with his cock in his hand.  
  
Ricky walked over to where Georgette was seated and let his cock bob in front
of him as he approached her. Georgette was stunned and lost for words. She
just watched as the handsome well endowed young man walked to her. Ricky took
his cock in his hand and stroked it inches from Georgette's face. Georgette
looked at it and she was drawn to it as if she were in a trance. She hadn't
seen a real cock in years and now this beautiful looking young phallus was
inches from her face.  
  
"Why don't you touch it Georgette? You know you want to. My mother liked
having my cock in her mouth, her pussy and her ass," Ricky pressed on.  
  
Georgette stared at the imposing but beautiful cock in front of her and as if
someone else was controlling her hand she grasped it. She just held it at
first and then she stroked it. She let her hand glide up and down the thick
long shaft and as she did she felt her loins stir with desire.  
  
"Now isn't that better? Why don't you kiss it now? My mother loves to kiss my
cock and I know you will too," Ricky urged her.  
  
Georgette moved her lips to Ricky's cock and she kissed the smooth helmet
head. She ran her tongue over his pee hole and caused Ricky to gasp aloud.
Georgette tasted his pre cum as it formed at the slit and then she covered his
cock head with her mouth. Georgette had now reached the point of no return and
she was determined to suck Ricky's cock until he ejaculated in her mouth.
Ricky closed his eyes and sighed as the principal gave him a first class blow
job. Georgette had not sucked a cock in years but she still remembered all the
right moves.  
  
Ricky was very sexually charged thanks to his alien companion and he knew that
he would cum quickly. He did not warn Georgette that he was going to cum but
just as she was running her tongue around the shaft of his cock, Ricky
ejaculated into her mouth. Georgette was stunned with the first jolt of cum as
it hit the back of her throat. She swallowed out of instinct as she knew more
cum was to follow. She no sooner swallowed the first load then another load
filled her mouth. This time Georgette swallowed and sucked Ricky's cock in
even deeper. The third and the fourth hit the back of her throat but then the
remainder trickled out of his cock onto her tongue. Georgette sucked on his
cock until it softened in her mouth and she had sucked him dry.  
  
Ricky eased his flaccid cock from Georgette's mouth and watched as she licked
her lips clean of any semen. He smiled at her as he relished his conquest and
then he guided her over to the sofa in her office. As if she were in a
hypnotic trance Georgette allowed her self to be led over to the sofa. Ricky
knelt down in front of Georgette and pushed her legs apart.  
  
He pushed Georgette's skirt up to her hips and leaned over to kiss her creamy
thighs. She gasped aloud at the touch of Ricky's lips to her naked skin. Ricky
knew that she was struggling with the decision on how far she should let this
go. Ricky was now aided by the alien who entered Georgette's body when Ricky
came in her mouth and she swallowed his load. He could smell the sweet aroma
of sex that was given off by her pussy as his face moved closer to her crotch.
Ricky lifted Georgette's legs to his shoulders and kissed her inner thighs
just below her panties. She groaned with pleasure as she reached down with her
hands as if to control his head. Georgette tried to keep Ricky's head from
reaching her pussy but he moved the panties to one side of her vulva baring
her sopping wet cunt. Ricky tickled her outer lips with his fingers and then
let them slip inside her vagina.  
  
Georgette was so wet that two of his fingers slid in easily and she
unconsciously relaxed her grip on his head. Ricky moved his mouth toward her
and closed it over her pussy shoving his tongue into her wetness. Georgette
cried out and grabbed his head again but this time she held it tight to her
quim. Ricky lapped at her pussy as he fingered her with two fingers. Then he
spread her pussy lips apart and located her throbbing clit peeking out from
its protective hood. Georgette was really excited as her erect clit looked
like a teeny dick sticking out. Ricky sucked on her hard clit and she bucked
her hips up into his face. Ricky reached under her and cupped her shapely ass
cheeks in his hands as he drove into her pussy with his tongue and nibbled on
her clit.  
  
"Oh sweet mother of God, I'm cumming. Hold me, please hold tight," Georgette
screamed as she lost it.  
  
The climax rocked Georgette's body and Ricky held on for dear life as she
thrashed, twisted and bucked all over the sofa. Ricky kept right on eating her
pussy and he held onto her shapely ass as she thrashed about. Georgette slowly
calmed after her intense orgasm and Ricky continued to lick her until her
pussy was dry. As Georgette lay back on her sofa Ricky continued to lick and
kiss her bare thighs above her stockings as she ran her hands through his
hair.  
  
"Oh that was something I really came hard. Thank you, thank you!" she murmured
almost unknowingly with her eyes closed and her head thrown back, the alien
now in control.  
  
Ricky then peeled off Georgette's panties. Georgette watched him as if she was
in a trance as he pushed his pants down to his knees and his rock hard cock
leaped out. Ricky moved between Georgette's thighs and he placed his cock at
the entrance to her cunt. Georgette shivered in anticipation. Ricky eased her
back down on the sofa and proceeded to feed his long thick cock to her.  
  
"Oh we mustn't, we shouldn't, it is not right and then oh yes, oh it feels so
good, oh, oh, fuck me, yes fuck", she cried.  
  
Ricky slid in and out of Georgette's pussy slowly allowing her to adjust to
his size and he continued to go deeper with each thrust until he was buried
balls deep in her pussy. Georgette was now his and she succumbed to his cock
just as his mother had. The alien was now having its effect on the principal
and she felt her breasts begin to ache.  
  
"Oh my I have never been so full of cock, fuck me, make me cum, make it last
forever", she cried out.  
  
Ricky pounded her pussy making sure that his cock was in constant contact with
her clit. Georgette had multiple orgasms as he fucked her. Ricky then pulled
her blouse out of her skirt and pushed it up over her bra. Then he reached
under her and unhooked the bra and pushed it up over her tits. Georgette's
tits had not gotten larger as she was a busty woman but they had gotten firmer
all of a sudden and her rock hard nipples extended out a ½ inch. Ricky twirled
the nipples in his fingers and then he leaned over taking one then the other
in his mouth.  
  
Georgette went wild telling him, "Oh yes, suck my tits, suck my nipples, fuck
me good!"  
  
Ricky could feel his balls start to tighten and he knew it wouldn't be long
before he filled Georgette's pussy with his cum. Georgette stiffened and then
had another violent orgasm.  
  
She yelled, "Hold me, please hold me, I'm cummmming!"  
  
Ricky reached around behind her and pulled her toward him as she shook and
trembled throughout her intense orgasm. As she was cumming so did Ricky and he
fired a barrage of cum into her pussy. As Georgette started to recover Ricky
laid her back down on the sofa and slowly fucked her as his cock remained
hard. Ricky's cock was swimming in Georgette's cunt; there was so much cum in
there mingling with her own juices.  
  
Ricky pulled out of Georgette's pussy and moved behind her on the sofa.
Georgette was turned sideways and Ricky nestled up behind her. Georgette could
feel Ricky's soft wet cock against her buttocks. Georgette was struggling with
her inner self, how could she have let this happen. It was the worst possible
outcome being seduced by a student. Her thoughts were interrupted by Ricky's
voice.  
  
"I hope that you like anal sex because that has become my favorite. Now it is
time for me to fuck your ass too," Ricky told her.  
  
"Please Ricky not my ass at least not here not now," begged the frightened
principal.  
  
"There is no better time or better place and my cock is ready for you," Ricky
pressed on.  
  
Ricky had Georgette kneel on the sofa as he located some lotion in her purse.
He returned to Georgette and he began to caress her lovely ass cheeks and
finger her nether hole. Georgette cooed when Ricky inserted a finger in her
ass and then another finger in her pussy. He sawed the two fingers in and out
for a few minutes loosening up Georgette's bung hole and putting her in the
mood. Ricky then added a second finger to Georgette's ass. He worked the two
fingers in and out of her ass stretching her as much as he could. Ricky then
placed his big erect cock between Georgette's beautiful smooth round ass
cheeks and pushed into her asshole.  
  
As he entered her Georgette pleaded, "It hurts, it hurts, please don't."  
  
But Ricky was not to be denied this beautiful ass and he was resolved to take
her. Georgette tried to move away from him but Ricky held onto her and pulled
her on his cock. Ricky had Georgette impaled on his huge cock between her ass
cheeks and in her asshole. Ricky began to hump Georgette at a slow pace and
then he fucked her quicker with his hips pumping into her. Georgette's moans
were louder than ever as her body took Ricky's big cock. Aided by the alien
present in her body, Georgette started taking Ricky's cock easier and
unconsciously massaged it with her amazing ass muscles. Ricky pulled her back
to her knees on all fours and reached around to feel her tits. Her nipples
were rock hard as he twirled them in his fingers. Ricky then moved one hand
down to play with her pussy and Georgette went wild humping her hips faster
and faster. Ricky then placed both hands on her hips and watched his cock
penetrate her curvy ass as she moved her hips in time with his humps.  
  
Georgette yelled out loud, "Oh my God, fuck me, fuck me, please fuck me!"  
  
Ricky complied with her demands and pounded her ass as hard as he could.
Georgette squeezed her ass cheeks together as she orgasmed and Ricky joined
her and shot a huge load of cum deep into her ass. Georgette screamed and
moaned as she felt Ricky pump several shots of cum into her rectum.
Georgette's beautiful body radiated heat as Ricky pumped cum into her ass.
Georgette was almost out of breath but started to return to normal breathing
as Ricky caressed her body lovingly. Ricky eased his cock from her ass and
traces of cum ran out of her asshole between her cheeks and over her pussy.  
  
Ricky was amazed at his capacity to produce cum. He had cum twice that morning
in his mother and now three times in the principal. Georgette tried to compose
herself as she cleaned herself up and got dressed. Ricky pulled his pants back
up and smiled at the principal.  
  
"We will have to do this again sometime," she said cockily.  
  
Georgette just nodded as she hung her head in shame wondering whatever
possessed her to behave like that. She just hoped that her moans were not
heard outside the room. Ricky left the office and the office staff had already
left. He checked the time and then he realized that he and georgette had been
fucking for hours. Ricky then hustled to the parking lot to meet Cindy who
would be waiting for him to take her home. CINDY AND RICKY  
  
Cindy was waiting by Ricky's car when he arrived. She was a little miffed but
forgave him when she learned that he was detained in the principal's office.
Of course she had no idea why he was detained. The parking lot was almost
empty so Ricky pulled his car over to a secluded area and began to make out
with Cindy.  
  
Cindy had worn a short skirt and sweater to school that day and as she and
Ricky made out in his car her skirt slid up and just covered her panties.
Ricky was too busy kissing her and feeling her firm tits through her sweater
to notice the skirt. Ricky slipped his hand under her sweater and caressed
Cindy's abs. She just cooed and made no effort to stop him when his hand moved
up to her breasts. Ricky massaged Cindy's jugs though her bra and his cock was
again bursting in his pants.  
  
Ricky reached behind Cindy and fumbled with the catch on her bra and again she
made no effort to slow him down. After unhooking her bra his hands returned to
her tits and he pushed the bra up over them. Ricky couldn't believe how firm
her tits were considering how big they were. Cindy now had her sweater and bra
pushed up over her tits when Ricky lowered his mouth to suck on her nipples.
Cindy gasped with desire as his mouth closed over her nipples and he sucked
one and then the other. Cindy and Ricky had been this far many times before.  

Ricky decided to go to the next step and he slid his hand along Cindy's creamy
thigh. She cooed as his hand traveled up her leg and under her skirt as Ricky
continued to suck on her tits. Cindy almost jumped through the car windshield
when Ricky touched her panty covered pussy. Her panties were dripping wet and
Ricky covered her mound with his hand. As Ricky rubbed her pussy and sucked
her tits, Cindy felt herself losing it and she knew that she would cum soon.
Ricky slipped his hand under her panties and eased one of his fingers into her
virgin pussy.  
  
Ricky gently fingered her pussy and then he took one of his hands and placed
it on his cock. Cindy couldn't believe the size of Ricky's cock as she felt it
through his pants. It had never felt that big before. Cindy began to hump
herself on Ricky's hand and finger as Ricky struggled to free his cock with
one hand. Ricky finally managed to free his cock from his pants and he guided
Cindy's hand back to it. Cindy grasped the thick shaft and began to stroke it
up and down as Ricky continued to finger her pussy.  
  
Ricky then reached under Cindy's skirt and pulled her panties down and off of
her. He then placed Cindy in the seat so that he could crouch down and eat her
pussy. Cindy went wild when Ricky's tongue pushed into her pussy and she
instinctively grabbed his head and held it in place. Ricky ate Cindy through a
continuous string of orgasms until she had to push him away. Ricky then tried
to get Cindy to sit on his cock but she was reluctant to fuck in the car.  
  
"I want to do it Ricky but not in the car," Cindy pleaded.  
  
Ricky was ready to bust a nut but he honored Cindy's request. Then he thought
of his house and hoped that his mother was not home. Ricky told Cindy that he
was taking her to his house and that they could be alone. Cindy actually was
turned on by the idea of fucking Ricky in his own house. Cindy agreed and they
left the school parking lot and drove to his house. On the way there Ricky
continued to finger Cindy's twat and play with her tits. Cindy continued to
play with Ricky's cock as well. An alien substance had traveled from Ricky's
mouth to Cindy's mouth when the two of them swapped spit. The alien was slowly
taking over Cindy's body while the alien in Ricky was refreshing his manly
reserve.  
  
When they arrived at his home Ricky took Cindy up to his room without checking
to see if his mother was home. Fortunately for them Rachel was visiting her
girlfriend down the street. Within minutes they were both completely naked and
in bed with Ricky's head back between Cindy's thighs.  
  
Ricky tickled her outer lips with his tongue and then let it slip inside her
vagina. Cindy was so wet that his tongue slid in easily and she unconsciously
tightened her grip on his head. He moved his mouth toward her and closed it
over her pussy shoving his tongue into her wetness. Cindy cried out and
grabbed his head again and held it tight to her quim. Ricky lapped at her
pussy, spread her pussy lips apart and located her throbbing clit peeking out
from its protective hood. Cindy was really excited as her erect clit looked
like a teeny dick sticking out. Ricky sucked on her hard clit and she bucked
her hips up into his face. He reached under her and cupped her shapely ass
cheeks in his hands as he drove into her pussy with his tongue and nibbled on
her clit.  
  
"Oh Ricky, I'm cumming. Hold me, please hold tight," she screamed as she lost
it.  
  
The climax rocked her body and Ricky held on for dear life as she thrashed,
twisted and bucked all over the bed. Ricky kept right on eating her pussy and
he held onto her shapely ass as she thrashed about. Cindy slowly calmed down
after her intense orgasm but Ricky continued to lick her until her pussy was
dry. As they lay on the bed Ricky continued to lick and kiss her bare thighs
as she ran her hands through his thick hair.  
  
"Oh I loved that. I really came hard!" she murmured.  
  
Ricky moved up between her legs as Cindy stared at the big cock about to enter
her pussy. She had never seen Ricky's cock so big before now but she couldn't
wait for him to fill her pussy with his meat.  
  
"Oh go easy and then oh yes, oh it feels so good, oh, oh, fuck me, yes fuck",
she cried out as the alien increased her desire.  
  
Thanks to the alien presence in her body, Cindy felt no pain when Ricky broke
her hymen. Ricky slid in and out of her pussy slowly allowing her to adjust to
his size and continued to go deeper with each thrust until he was buried balls
deep in her pussy.  
  
"Oh my, this is wonderful, fuck me, make me cum, make it last forever", she
cried out.  
  
Ricky pounded her pussy making sure that his cock was in constant contact with
her clit. Cindy had multiple orgasms as he fucked her. Cindy had large firm
tits with rock hard nipples that extended almost an inch now. Ricky never
remembered her nipples being so big and so hard. Ricky twirled the nipples in
his fingers and then leaned over taking one then the other in his mouth.  
  
She went wild telling me. "Oh yes, suck my tits, suck my nipples, fuck me
good!" and then she screamed, "Hold me, please hold me, I'm cummmming!"  
  
Ricky reached around behind her and pulled her toward him as she shook and
trembled throughout her intense orgasm. As she was cumming so did he and he
fired a barrage of cum into her pussy. As she started to recover Ricky laid
her back down on the bed and slowly fucked her as his cock softened. Ricky's
cock was swimming in her cunt. Ricky eased his big cock out of her pussy and
lay down beside Cindy on the bed. He reached over and stroked her large firm
tits and hard nipples as she still breathed deeply from the intensity of her
orgasm. After a few minutes Ricky was hard again so he rolled Cindy over on
her side and slipped his big cock back in her pussy. He reached around with
both hands and held on to her big tits. Ricky let her nipples slip between his
fingers and he held her nipples in a scissor grip as he fondled her big tits.
Cindy never knew that sex would be like this, so intense and so frequent.
Ricky seemed to be tireless and Cindy was beginning to feel insatiable. She
wanted Ricky to fuck her forever or at least as long as they both could last.
Ricky then slid his cock from her pussy to her ass and pressed ever so
slightly then he put it back in her pussy and then he repeated the action.  
  
Ricky began dipping the head of his cock into Cindy's wet pussy and then
sliding it back to her ass. It made her body quiver. Cindy pressed against
him, wanting his dick inside her pussy, needing to feel him in her. The head
of Ricky's dick was coated with the wetness from Cindy's pussy and his cream
from his earlier cum shot. Ricky used his fingers and cock to smear the
slippery natural lubricant around on Cindy's inner thighs and the crack of her
ass. Ricky pressed his wet, throbbing dickhead against her tight asshole, and
continued to stroke and rub softly against the lips of her pussy.  
  
Ricky did not hurry his actions, even though he could feel Cindy straining
frantically against him. He continued to finger Cindy slowly and fondled her
tits gently, teasing her body mercilessly. Although Cindy was aware of his
cock pressing against her asshole, her attention was focused on the feelings
flooding through her nipples, clit, and pussy. Even though the movements of
his fingers were tender and measured, her erect nipples and distended clit
throbbed and pulsed with desire. Ricky continued pressing his dick into
Cindy's ass with the same slow steady rhythm.  
  
Cindy realized that Ricky wanted to put it in her ass and panicked and
pleaded, "No please not that. I don't want to do that. Please Ricky everything
has been so wonderful don't ruin it for us!"  
  
Ricky honored Cindy's request and backed off her ass. She was right it had
been great to this point so why make her do something that they both may
regret. Ricky rolled on his back with his large cock sticking up in the air.
Cindy rolled over and then she had the oddest desire to take his big cock
between her tits. Cindy moved down Ricky's body and positioned her tits over
Ricky's cock. Then she held the cock between her tits and rocked back and
forth. Ricky was turned on by Cindy's action and he got into it. He lifted his
hips up and down as if he was fucking her and the combined actions had the
desired effect. Ricky felt his balls tighten with his impending ejaculation
and then he shot his wad right between her tits. Ricky's first cum shot hit
Cindy in the chin and then the other streams coated her cleavage and his abs.
Ricky's cock pulsed and throbbed as the cum shot out of his cock and Cindy
could feel the cock throbbing between her tits.  
  
Cindy then did something she had never done before and she took Ricky's cock
in her mouth. She caressed his bloated balls and sucked the remaining cum from
his cock. Then the two of them embraced and kissed each other. Ricky's cum was
pressed between their bodies and they embraced. Cindy felt a glow about her
that she had never felt before. Then they heard a noise downstairs and Ricky
knew his mother had come home. The two of them dressed quickly and then left
Ricky's bedroom and went down stairs.  
  
Ricky's mother Rachel saw the teenagers and she knew immediately that they had
been fucking. There would have been a time when Rachel would have been furious
but not today. She was pleased that her son was fucking Cindy and she
immediately though that they could have a foursome sometime with her husband.
Rachel decided to invite Cindy over for a cookout on Saturday.  
  
"Cindy why don't you join us for a cookout this Saturday," Rachel offered.  
  
Cindy was pleased that Ricky's mom didn't yell about them being in the house
alone and she accepted the invitation, "I'd like that. Thank you!"  
  
"Great please come over about two o'clock," Rachel confirmed.

        Aliens Use Sex to Invade Humans Ch. 04


Author's note: I received an e-mail requesting that I write a story about
aliens taking over humans and creating insatiable sexual desires. The person
requesting this story had read another story on Literotica entitled Hosts. He
was disappointed that the author of Hosts did not write any more chapters
after the first submission, which is why he asked me to write about this
topic. It is my first venture into this story category so let me know what you
think. I will continue with story if the feedback in encouraging. Thank you!

CHAPTER 4 – AARON MEETS HIS SON'S ROOMMATE  
  
AARON CATCHES HIS SON IN THE ACT  
  
Aaron had returned home from the NASA debriefing and his son Billy was home
from college. Billy had brought his college roommate Butch home with him for a
visit. That night the three of them sat around talking and Aaron described his
experience on the space station but he did not tell the boys about all the
sex. The three of them had a few beers while they talked and then it was time
to turn in.  
  
The next morning Aaron was awake before the boys and he went down to the
kitchen to make coffee. He wished that his ex-wife was still around as he was
extremely horny and his dick had stayed hard all morning. His ex-wife Shelia
had divorced him as she got tired of the life as an astronaut's wife. As the
coffee was brewing he decided to check in on the boys. He went upstairs and
was about to knock on his son's bedroom door when he heard Billy's voice.
Aaron could hardly make it out through the closed door but he was sure that
Billy was urging Butch to fuck him. This he had to see for himself. Aaron
opened the door quietly and peeked through the crack. Sure enough Billy was on
all fours and Butch was fucking him from behind.  
  
As Aaron watched the boys fuck he felt his own cock harden again in an
instant. Aaron, with the alien's help at that moment, decided to fuck the two
boys. He stripped off his shorts and his big eleven inch cock sprang to
attention. Aaron entered the room quietly and walked around in front of Billy.
Both Billy and Butch were shocked to see Aaron in Billy's room but they were
even more shocked to see him naked with his big eleven inch cock fully erect.
They stopped fucking and they both stared at his imposing cock.  
  
"I thought that you two may like to have some company," Aaron said as he waved
his big dick in front of Billy's face.  
  
"Oh my God dad, we've never done it with anyone else," replied Billy in
embarrassment.  
  
"Do it Billy, suck his cock. It's okay it's your dad. Let's make it a
threesome," the always assertive Butch urged, "God look at the size of your
dad's cock."  
  
Billy tentatively reached for his father's cock. He held the long thick cock
in his hand briefly before he finally licked the head with his tongue. Billy
couldn't believe the girth on Aaron's cock as he could not wrap his hand all
the way around it. Billy opened his mouth and took the head into his mouth and
he felt his jaw strain to accommodate his father's size. Billy only took about
four inches of Aaron's cock into his mouth and began to suck on it. Butch
resumed fucking his roommate as Billy sucked on his father's cock. The three
of them were turned on and it didn't take long for Butch to cum and fill
Billy's ass with his first massive load of the day.  
  
Aaron loved the blow job he was getting from his son as it was as good as any
he ever had. Even though Billy was still adjusting to Aaron's size he did a
good job sucking his cock. It had been a few days since Aaron had had sex so
when he came he flooded Billy's mouth. Billy was taken back by the force and
amount of cum that his father shot into his mouth. Billy had to pull off
Aaron's cock to keep from gagging and the remainder of Aaron's cum splashed
off of Billy's forehead and face. Butch emptied his balls into Billy's ass as
he watched Aaron's massive load hit Billy's face. Billy wiped cum off his face
and licked his fingers clean. As Billy swallowed his father's cum an alien
substance made its way into Billy's system.  
  
"I need to cum," Billy gasped.  
  
Butch moved into position to be fucked and Billy got the lube and prepared
Butch's ass. As Billy was fingering Butch's shapely ass Aaron decided that he
would fuck his son. Aaron took the lube and fingered Billy's ass. Billy was
leery of Aaron's big cock and he hoped that his father wouldn't try to fuck
him. Billy slipped his cock into Butch's ass and began fucking him while Aaron
continued to finger fuck Billy. Billy actually liked the anal penetration as
he fucked his roommate and he wished that his father had a smaller cock so
that his father could fuck him.  
  
Aaron satisfied that Billy's ass was well lubed applied a generous amount of
lube to his own cock. Aaron moved in behind Billy and pushed his cock into
Billy's asshole. Billy panicked and pleaded with Aaron not to fuck him.  
  
"Dad please no, you're too big, I can't take you in my ass," Billy begged.  
  
"Nonsense, if Rachel, Sam and Carl could take my cock in their ass you
certainly can. You just need to be broken in some more," Aaron replied. Billy
then remembered that Rachel, Carl and Sam were astronauts on the space shuttle
with his dad.  
  
"Fuck him Aaron, fuck his ass just like he's fucking mine," Butch urged.  
  
Billy's fate was sealed and Aaron eased more of his cock into Billy's ass.
Aaron was gentle though relentless in his quest to fuck his son. Aaron would
push in a little and stop allowing Billy to adjust along the way. Finally
Aaron began a rocking motion and began fucking Billy slowly. Billy's ass had
stretched enough now that he was comfortable with Aaron's cock in him and he
resumed fucking Butch. As Billy picked up the pace fucking Butch in the ass he
was pushing his own ass back onto Aaron's cock. Then something happened to
Billy. Butch's ass was tightening around Billy's cock. Billy had never felt
Butch tighten his anal passage as he was doing now as Billy's cock was being
squeezed.  
  
"Holy shit Billy your cock is getting longer and thicker in my ass. What the
hell is happening?" Butch yelled.  
  
Billy then realized that his cock was growing in size in Butch's ass but how
could that be happening? Aaron stopped moving as he didn't have to while Billy
was fucking Butch. Billy would bury his cock in Butch and in the process his
ass would slide along Aaron's cock. When Billy withdrew slightly from Butch's
ass he impaled his ass on Aaron's cock. Aaron inched closer and closer as
Billy seemed to be able to take more and more of his cock. Then Billy felt
Aaron's pubic hair brush against his buttocks and he realized that Aaron was
all the way in his ass. Billy couldn't believe that he had taken all of his
father's big thick cock. Billy was proud of himself now and he picked up the
pace fucking Butch and impaling himself of Aaron's cock.  
  
Aaron came before Billy did but when Billy felt cum shoot into his ass he lost
it. Billy's buttocks tightened as he plunged his cock all the way into Butch's
ass and unleashed his first load of the day. Billy flooded his roommate's
rectum with an enormous load one of the largest he could remember. As Billy's
buttocks clenched and unclenched as he came in Butch's ass, he milked every
drop of cum from Aaron's cock. Aaron caressed Billy's shapely ass as he let
his cock be milked dry. Aaron liked looking at the tanned boys with their lily
white asses. The fact that they had tan lines emphasized the shape of their
curvy bottoms.  
  
Butch was erect again after the fuck session and he stared in amazement as he
watched his cock grow in front of his eyes. Butch too had been invaded by the
alien who now took over his body. Butch felt the tremendous need to cum so he
had Billy suck his cock. Aaron watched Billy suck his friend's cock and then
he too got hard again. Billy was also hard again after sucking his friend and
swallowing his load. This time Butch would take Aaron's cock in his ass as he
sucked Billy's cock. The three of them fucked and sucked until they were
drained and exhausted.  
  
Aaron, Butch and Billy finished their marathon fuck sessions. Aaron had fucked
and cum in both Butch's ass and Billy's ass while the boys took turns sucking
each other's cock. Then Aaron was blown by Billy as Butch fucked Billy in the
ass. Then Butch had sucked Aaron's cock while Billy fucked Butch's ass. Aaron
had cum four times, once in each of the boy's holes. They lay drained on the
bed and then Aaron told the boy's of his plan for them to fuck Billy's mother.
The boys listened intently and excitedly as Aaron told them about inviting
Shelia over. Aaron lied to the boys when he told them that Billy's mother
always had a secret desire to have sex with two or three men at the same time.  
  
"Really she wants to have group sex?" asked Butch not hiding his excitement.  
  
"Yes she does I can think of no better partners than you two. Just wait until
she sees your big cocks and mine," Aaron told them.  
  
The two boys looked at their renewed cocks and they were mystified how they
had grown in just one day. Aaron knew something was awry because every time he
had sex with a male their cocks got longer and thicker just like his. When he
had sex with a woman her body changed for the better and she became
insatiable. He also had the capacity for more sex than ever in his life. He
knew that it had to have something to do with his time in space. He still
remembered how insatiable he, Rachel, Sam and Carl had become in space. Now he
was planning the seduction of his ex-wife with the help of his son and another
boy.  
  
"Fuck my own mother! No way I couldn't do that besides I have never fucked a
pussy," Billy blurted out.  
  
"You don't have to fuck her pussy, I'll do that. You guys can take her ass and
her mouth. She loves it in the ass and she loves to suck cock," Aaron lied.  
  
Then the assertive Butch spoke out, "Let's do it. Billy you fuck your mother
in the ass and I'll fuck you in the ass. Then we will switch and I bet with a
cock in our ass we can stay hard and fuck your mother."  
  
"I don't know Butch, my Mom?" Dannie questioned.  
  
"You heard Aaron, she loves it and she wants it. I say we do it," Butch
affirmed.  
  
Aaron left the two boys in his son's bed to call his ex-wife.  
  
SHELIA IS SEDUCED BY THE ALIEN POWER  
  
Shelia took her ex-husband's phone call and took the bait that her son wanted
to see her. Shelia made her way over to the house the next day but when she
arrived, Aaron told her that Billy had stepped out for a moment. Aaron under
the alien's power kissed Sheila deeply but she stepped back and slapped him.  
  
"What do you think you are doing?" she screamed at him.  
  
"Sorry it's been so long and I am happy to see you," Aaron explained his
action.  
  
"That's no excuse, you know I am seeing Roy these days," she said sternly.  
  
But the kiss had been just wet enough for an alien substance to transfer to
Shelia and as it made its way through her body she felt the change in her.
Aaron noticed the change too and he took her in his arms and kissed her again.
This time she kissed him back and they began to rip off each other's clothes.
Sheila's tits got bigger and firmer, her waist got narrower and her stomach
tightened up. She stared at Aaron's cock and it was almost twice the size that
she remembered. Aaron picked her up and carried her into his bedroom and she
forgot all about her son for the moment. Aaron lay on his back as Shelia began
a slow descent from his lips to his massive cock. Soon she had Aaron's rock
hard cock in her mouth. Aaron turned around so that he could get to her pussy
and he began to eat her as she sucked his cock.  
  
"I can't believe that I am getting so hot," Shelia said, "I have to have your
cock in me I am going to sit on your cock," she gasped.  
  
Shelia straddled Aaron's body and lowered herself onto his cock. She moaned as
it filled her pussy and then began to slowly rock back and forth. It was
obvious that she wanted this fuck to last for awhile. Aaron cupped her ass as
she rocked back and forth and then he began to play with her asshole. He
grabbed the lotion near the bed and applied a generous amount to the crack in
her buttocks. He pushed one then two fingers into her asshole as she continued
to ride him. Aaron could feel his own cock in her vagina through the thin
membrane. Shelia was going wild with the double penetration and she humped him
faster and faster.  
  
"Oh this is going to be a big one, hold me hold me," she pleaded.  
  
Aaron held her tightly as Shelia exploded with an intense orgasm. Shelia shook
and moaned as she squirted her woman cum all over his cock. She collapsed on
Aaron's body as he continued to fuck her slowly. Aaron looked over her
shoulder and saw Billy and Butch standing there naked and both sporting huge
erections. They must have come in the room while Shelia was cumming. Aaron
smiled and motioned to Billy pointing to Shelia' ass. He nodded getting
Aaron's meaning. Aaron nodded toward the lotion on the table and Billy picked
it up. He lathered up his cock with the lotion and then he moved toward the
bed. Aaron grabbed Shelia's buttocks and pulled them to the side putting her
asshole on full display. She was starting to get aroused again so she resumed
her movements on Aaron's cock. Billy knelt on the bed and aimed his dick at
his mother's asshole.  
  
She stiffened when she felt the intrusion. "What the," she exclaimed!  
  
"It's okay it's Billy and his roommate Butch," Aaron assured her.  
  
Billy eased his cock all the way into her ass and began fucking her. Soon the
father and son had a good rhythm going and they could feel each other's cock
through the thin membrane separating them. All of this was too much for Butch
and he lubed his cock with the lotion and knelt behind Billy to fuck him in
the ass.  
  
"Billy you shouldn't being doing this! Where is your friend Butch?" Shelia
questioned.  
  
"Right now he is in Billy's ass fucking him as we fuck," Aaron replied.  
  
"Sweet mother of God," she exclaimed somewhat in shock!  
  
Their cocks were sliding in and out of Shelia in perfect harmony. As Aaron
slid out of her cunt Billy filled her asshole. When Aaron filled her pussy
Billy slid out of her ass and experienced Butch's cock penetrating his ass
fully. Aaron had the best vantage point and he could see the looks of ecstasy
on their faces. Shelia was moaning and trembling with the double penetration
and Billy was in another world as he fucked and got fucked at the same time.
Butch had a look of determination on his face as he pounded Billy's ass.  
  
They kept on fucking one another and they were getting close to cumming when
Billy called out, "Oh Butch, oh Butch."  
  
Butch called back to him, "Its okay we are all cumming."  
  
Butch yelled, "I'm going to shoot."  
  
Aaron watched Butch stiffen and bury his cock deep in Billy's ass as he filled
it with his man seed. This seemed to set Billy off as his body stiffened at
first and then leaped several times like a coiled spring as he came in
Shelia's ass. Shelia felt Aaron's cum fill her womb for the first time that
day. It seemed that Aaron would not stop cumming as he fired streams of cum
into her filling her pussy to overflowing. Shelia collapsed on top of Aaron
crushing her larger firmer breasts into his chest as her hips gyrated out of
control. Aaron could feel her juices soaking his cock once again. The looks on
all the faces were ones of bewilderment and ecstasy.  
  
They all lay still on top of one another as the three bodies had collapsed
with Aaron on the bottom. Finally one by one they separated. Billy and Butch
stood beside the bed and they all looked at one another somewhat in disbelief
of what just happened. Shelia finally broke the silence. Shelia sheepishly got
out of bed and ran into the bathroom. She was clearly embarrassed by what had
happened but most of all she was embarrassed because she had enjoyed it so
much.  
  
Butch exclaimed, "Man that was the wildest sex I have ever been involved in."  
  
Butch continued, "To see your mother being double fucked was unbelievable and
I was so turned on I just had to join in and fuck Billy."  
  
"Yeah, it was pretty wild okay. I wasn't sure how she would react but she did
seem to get into it," Aaron replied.  
  
"She is probably thinking about it in the bathroom and trying to figure out
what she will say to us," voiced Butch.  
  
They continued a three way conversation about the sex act and replaying how
they felt. As they talked Aaron noticed that Butch and Billy were getting hard
again. The amazing recuperative powers triggered by the alien were at work
once again. Then they started to play with each other's dick and soon they
were ready for more action.  
  
"This time I fuck you" Billy said to Butch.  
  
Butch got up on all fours and arched his back wiggling his bubble butt at
Billy. Billy slipped behind him and re-lubed his cock and Butch's asshole.
Billy slid in easily to the well used ass and began to fuck Butch.  
  
"Aaron, stick your cock in my mouth, please" Butch requested.  
  
Billy then coaxed me, "Dad do it. I want to see him suck your big cock again
while I fuck his ass."  
  
Aaron moved over to Butch and presented him with his semi-erect cock. Butch
took Aaron in his mouth and before long he had him rock hard. Butch was a very
accomplished cocksucker and he knew just how to keep Aaron hard until he came.
Billy was fucking Butch's ass as Butch was sucking Aaron's dick. Butch had a
hard-on just from the action he was getting.  
  
Aaron looked up to see the bathroom door open and saw Shelia standing there
watching them suck and fuck. She dropped her towel and moved closer to them.
She looked down at Butch's erection and then shocked everyone all by dropping
to her knees and taking the cock in her mouth. Billy and Aaron smiled at each
other as Butch gasped on Billy's cock when he felt Sheila's mouth envelop his
dick. This act by Shelia set the guys all over the edge and all of them
ejaculated into the accompanying receptacles.  
  
Aaron filled Butch's mouth with cum as Billy filled Butch's asshole with his
seed. Butch moaned and groaned as he filled Billy's mother's mouth with his
cum. Shelia continued to suck on Butch's cock until she had drained him of all
his cum. Butch collapsed on the bed with Billy behind him. Aaron sat on the
bed and Shelia sat next to him. Aaron lay on his back so that Shelia could
straddle his cock as she did before. She slowly sank down burying Aaron's cock
in her juicy cunt. Billy lubed up his cock and her ass and slid his dick into
her bunghole. Butch presented her with his hard cock. Shelia started going
wild humping two cocks and sucking another. Aaron could feel her squirting her
pussy juice all over his cock. She was incredibly turned on.  
  
Billy called out, "Butch switch with me."  
  
Butch and Billy traded places as Billy presented his hard cock to his mother's
mouth and Butch slid his huge erect dick into her ass. This was more of a
turn-on then they expected and soon we were all cumming in Shelia's holes.  
  
Butch strangely enough was the first to cum and screamed out, "Oh man, I'm
cumming, I'm doing it, and I am cumming in your ass."  
  
Billy came next flooding his mother's mouth as Aaron filled her womb with a
generous amount of cum. Shelia shook with her own orgasm and collapsed on
Aaron as Butch collapsed on her.  

Over the next 24 hours Shelia had sex with her son, her ex-husband and Butch
continuously. Some times she had three cocks in her at the same time. Other
times Shelia had sex with Aaron alone or with her son. Billy was only
comfortable fucking his mother in the ass or letting her suck his cock. Butch
agreed to fuck her pussy to see if he could and he was able to remain hard and
cum in her pussy. Shelia was thrilled because now she could have Butch in her
pussy and Billy in her ass and they were all able to cum. Shelia still sucked
her son's cock while they fucked each other in the ass. Shelia had waited a
long time for sex since her divorce and now she had more than she would ever
have imagined.  
  
Aaron balanced his time between Shelia and the boys. There were times when he
just fucked the boys and let them suck his cock. Other times he was with
Shelia and he would cum in all three of her orifices. And at other times the
four of them all had sex together. Sheila didn't want to leave the house as
she loved the attention she received from the three large cocks but she
eventually had to go home and the boys had to go back to college. Sheila knew
she would be back to sample more of her husband's renewed huge cock.  
  
Aaron was still curious about the changes that happened to his body and others
when he had sex. He decided to call Rachel, Sam and Carl to learn what they
were experiencing. If they were having similar experiences, Aaron decided that
he would contact NASA and report the unusual behavior.  
  
CINDY AND HER FATHER  
  
Cindy always slept in the nude and many a morning her hands would travel over
her body caressing her tits and fingering her pussy as she reflected on her
boyfriend. Sometimes Cindy got carried away and she moaned softly as she made
herself cum. Her actions did not go unnoticed. Her father Mike was usually
awake when he heard his daughter's moaning from time to time. One morning he
was awake earlier when he decided to look in on his daughter. He quietly
opened her bedroom door and stared at her fabulous naked body. Mike was very
turned on by his daughter's nakedness and found himself desiring her. Over the
past few weeks, he would watch her for longer periods each time and then head
back to his bedroom to jerk off while fantasizing about fucking his daughter.
Mike would go to his daughter's room right after his wife left for work so
that he could spend more time looking at his naked daughter.  
  
Mike began to get bolder and bolder with each visit to his daughter's room. As
he watched his naked daughter in bed he began to stroke his cock. He had
gotten to the point where he didn't return to his bedroom to jerk off but he
stayed in his daughter's room and ejaculated there. One morning Cindy realized
that her father was in the room and she made believe she was still sleeping.
She peeked through her half closed eyes and watched her father masturbate as
he looked at her body. Cindy was pleased that her father was turned on by her
naked body and that he would cum just from looking at her.  
  
Cindy looked forward to the morning visits from her father to look at her
naked body. She became to tease him relentlessly as she faked being asleep and
having erotic dreams. Cindy would roll over on her stomach so that her father
could see her ass then she would roll on her back and open her legs so he
could see her pussy. Cindy made believe she was dreaming and ran her hands
over her body moaning as she caressed her tits and stroked her vulva. Mike was
going mad as she watched his daughter and his hand flew over his cock. Cindy
rolled over on her stomach and lifted her hips off the bed slightly as she
fingered her pussy. Her father went wild looking at his daughter's undulating
ass.  
  
The morning after her torrid sex with her boyfriend Ricky, Cindy took it one
more step as she fingered her pussy, "Oh yes fuck me," she whispered loud
enough for her father to hear.  
  
That did it for Mike he simply had to have his daughter. Mike stripped off his
clothes and crawled in bed with his daughter. He moved between his legs and
put his mouth right on her pussy. Cindy gasped when she felt her father's
mouth cover her vulva and almost screamed out when his tongue penetrated her
pussy. Cindy was overcome by the sensation. Cindy shivered and trembled under
her father's hands and kisses. Then she cried out when Mike first swiped her
pussy with his tongue. Mike lifted her legs up to his shoulders as he covered
her pussy with his mouth. Mike could the feel the firmness in Cindy's thighs
and firm quads. She clamped her legs tightly around her father's neck as he
delved in to her inner depths. Mike located her erect clit and sucked it into
his mouth emitting an audible gasp from her. Mike then reached under her and
grabbed a hold of her curvy buttocks. Mike loved the firmness of his
daughter's muscular ass cheeks as she tightened them. Cindy was really hot and
she humped her father's face as he sucked on her clit. She started to cum and
Mike held her thrashing body tight against his mouth. His hands dug into her
firm ass flesh as she went wild with her first orgasm ever from oral sex.  
  
"Oh, oh, oh God, her it cums," she screamed as her orgasm rocked her body.  
  
Mike held his daughter tight and sucked every drop of female love juice from
her pussy. Cindy writhed and gasped all throughout her intense orgasm until
finally her climax subsided and her body calmed. Mike licked her tenderly
until she couldn't take any more and she gently pushed her father's head away
from her pussy. There was no more pretending now as they both became lovers.
Then Mike felt the strange feeling pass through his body as the alien had
invaded him through his daughter's nectar.  
  
"Wow that was incredible Daddy!" she sighed.  
  
Cindy leaned over and took her father's cock in her mouth gently nibbling on
the cock head. Mike was a little surprised by his daughter's action but she
had obviously done this before. Mike fondled her tits as she sucked him deeper
in her mouth. Cindy took her mouth off of his cock long enough to tell her
father that he had a beautiful cock and then she sucked it back in her mouth.
Cindy sucked her father for awhile longer until she was hot again. Mike was
stunned as he watched his cock grow to new dimensions.  
  
"I am really hot. I need your cock in me Daddy," she gasped.  
  
Cindy lay back in bed, spread her legs and she beckoned her father to come to
her with her arms open. Mike knelt between her thighs and slipped his cock
into her pussy. Cindy closed her eyes and sighed as her father's rock hard
cock entered her. Mike began to fuck her slowly as his now huge cock settled
into her snug pussy.  
  
"You feel good in me. I like your big cock in my pussy," she told him.  
  
Mike's cock was all the way in now and Cindy wrapped her muscular legs around
his lower torso. They picked up the pace as they fucked and Mike soon found
himself pounding Cindy's pussy. She pulled her father into her with her strong
legs as he fucked her and they both raced toward their climax. Mike could feel
his orgasm building in his balls and he knew it would be a big one. One more
thrust and Mike's body tightened as he emptied his balls into his daughter's
pussy. Cindy felt the surge of his semen flood her pussy and she fucked even
faster in search of her own climax. Cindy made sure that her clit stayed in
contact with her father's shaft as she raced toward her orgasm.  
  
Cindy stiffened and cried out that she was cumming as her legs clamped tightly
around her father's body. Her pussy involuntarily squeezed his cock. Mike
could feel the vaginal muscles clench and release his cock over and over again
until his daughter finally went limp under him. They were both sweating from
the intense fuck session when Mike rolled to his side allowing his softening
cock to slip from his daughter's cunt. Cindy just lay on her back looking up
at the ceiling and breathing shallowly.  
  
"Daddy you are a good lover. That was a great fuck," Cindy sighed.  
  
"I would say that you are very good yourself," Mike replied softly.  
  
Cindy snuggled into her father and he put his arm around her. He stroked her
firm tits and teased her rock hard nipples as they lay together. They didn't
say much as they lay together but Cindy began to stroke her father's cock and
held it lovingly in her hand. Mike started to harden again and she smiled at
his response to her fondling. Cindy slid down her father's body and took his
cock into her mouth again. Mike moved his daughter's hips over his face so
that he could lick her pussy and they settled into a comfortable 69 position,
another first for Cindy. He caressed Cindy's incredible ass and teased her
nether hole as they ate each other. Mike moistened his daughter's asshole with
her own pussy juice and his saliva before pushing his finger into her ass.
Cindy seemed to accept the finger in her ass and they ate each other until
they both came again and then returned to a side by side position.  
  
Mike got Cindy out of bed to shower with him. He loved washing her sexy body,
soaping her tits, fingering her pussy and her asshole. Mike slipped a soapy
finger up his daughter's ass and fondled her curvy firm buttocks. His cock was
back at attention so he moved behind her and slipped his cock into her soapy
asshole. Cindy grunted as her father's cock penetrated her lovely ass and she
leaned forward to place her hands on the shower wall. Cindy arched her back
accentuating her shapely ass as she leaned forward. The sight was incredible
as Mike slid his huge cock in and out of his daughter's beautiful ass. The
scene was even more erotic given that they were in the shower and his
daughter's skin glistened with moisture. Mike tired to prolong the ass fuck as
long as he could but he was so turned on that he came quickly. Mike flooded
Cindy's ass with his seed and she groaned as it filled her anal cavity.  
  
Mike was able to stay hard and he kept fucking his daughter's ass even though
he had emptied his balls. He was now able to manage back to back orgasms
without losing his erection. He fucked Cindy's ass until he came again. It
took a while before he came again and he was able to savor the incredible
sight of his cock sliding in and out of his daughter's marvelous ass. Mike's
cock softened and slipped from Cindy's ass and they stepped out of the shower
just as the water was starting to turn cold.  
  
They went back to be and Mike couldn't believe his renewed capacity for sex or
his daughter's insatiable sexual appetite. She watched as him as he crawled
between her parted legs. He parted them even wider, taking his time to look at
her wet snatch in detail. Then he slowly lowered his head, breathing in deeply
and smelling her sex. Cindy could feel his breath on her snatch when he
suddenly opened his mouth and licked the length of her slit. Cindy writhed
with pleasure and played with her tits. Mike teased her with his tongue for a
while and then he used it to part her pussy lips encountering more wetness. He
lapped up her juices and started flicking his tongue across her clit. Cindy
moaned louder and louder as Mike knew exactly how to please her hungry cunt.
He sucked on her clit for a while and then he slid his tongue inside her tight
hole. He tongue fucked her, faster and deeper, applying pressure to her clit
with his nose. Cindy pulled at the headboard with her hands as she wrapped her
legs around her father's shoulders and thrust her hips up to feel more of him.
When she couldn't hold back anymore she cried out loud and her pussy juices
showered his face as she orgasmed.  
  
He crawled up next to her and kissed her deeply, sharing the juices with her.
Cindy could feel his cock getting hard against her hips again as he lowered
his head and started sucking her nipples. It felt so good. He sucked and bit
her tits, pulling them and kneading them. Cindy was soon on fire again and she
wanted his cock so badly.  
  
"Fuck me, Daddy," she begged breathlessly.  
  
"That's better," he smiled. "Pull your legs up and open yourself wide for me."  
  
Cindy did as she was told. She grabbed hold of her legs and pulled them wide
apart, showing off her dripping pussy. Mike kneeled by her cunt and jerked his
cock, getting it really hard. He ran his cock head the length of her wet slit
and then he entered her cunt with the thick cock head and stopped there.  
  
"Oh yeah, baby," he gasped. "You're so hot. I love fucking your cunt."  
  
"Oh yes," she moaned. "Fill me with your thick meat."  
  
With those words he slowly started burying himself deeper inside her cunt.
Cindy felt herself stretching to accommodate his full size and he felt great
inside her. This was what a cock was supposed to feel like. This slow,
torturous pleasure was what fucking was supposed to be like. When he was
buried all the way inside her cunt he stopped, smiled at her and started
sucking her tits again. They lay like that for minutes. Her father's cock was
firmly lodged in Cindy's hungry cunt and he was sucking her nipples. She was
impatient to feel more but he refused to move. He was in control of her
pleasure.  
  
When he was ready he placed his hands on either side of her to give himself
support and then he slowly slid his fuck meat almost completely out of her
cunt. Only the tip was still inside her hole and Cindy moved her hips upwards
to get him back. She wanted him to fuck her. She wanted him to fill her again.  
  
"Fuck me, please!" she begged him.  
  
Then he quickly pounded back inside her again. His balls slammed into her ass
as he filled her cunt. He pulled out again and slammed back inside. With an
ever increasing pace he was burying his cock deeper and harder inside her
tight hole. He slammed inside his daughter harder and harder and every thrust
went straight to her clit, sending an electric shock through her body.  
  
Cindy was breathing faster and faster. She couldn't believe the pleasure he
was giving her. She loved every moment of the fucking. She moved her hips to
meet his thrusts, to get as much of his fuck meat inside her. She could hear
the sounds of their fucking get wetter and wetter as her hungry cunt worked
overtime to produce more juices. She knew that she wouldn't last much longer.  
  
"I've got to cum," she panted.  
  
"Oh yeah, baby," he whispered against my skin, "Cum for your daddy!"  
  
With those words she felt her pussy contracting tight around his shaft. He
kept fucking her at the same pace as before while her pussy shivered and
convulsed around his thick meat. When she was done cumming he pulled out and
put her on my hands and knees. He wasn't done yet. His cock was still big and
hard and he was going to get satisfaction from her pussy.  
  
He easily slid his cock into her waiting hole. Cindy was ready to take his
cock again. He managed to get even deeper from behind. He slammed harder and
faster now. Each thrust sent his balls crashing into her sensitized clit. Then
he pulled her up by her tits and with her full breasts in his hands he nibbled
at her neck.  
  
"Your cunt is so sweet and tight, baby," he whispered as he kept pumping into
me, hitting her womb with every thrust, "You make daddy feel so good."  
  
Cindy's breathing grew heavier and she knew that she was about to surrender to
his fucking once more. Her pussy squeezed tight around his cock and her body
shook. She moaned out loud and Mike stopped his fucking. With her pussy
gripping his cock hard and milking him he thrust deep inside her and roared as
he released his spunk straight up her hungry cunt.  
  
When we'd both stopped cumming he pulled out of her and collapsed next to her
on the bed. They were both sweaty from the sexual exercise and he pulled her
tight into his arms.  
  
"You are a great fuck, baby," he said and smiled.  
  
She kissed him as she heard those wonderful words. Cindy straddled him and he
guided her father's cock back into her cunt. She rode him fast and furiously
as he played with her bouncing tits.  
  
"God, you're insatiable, Daddy. That lovely cock is ready for more." Cindy
gasped.  
  
"Do you mind?" Mike quipped.  
  
"Of course not do what you like. I'm yours for your pleasure. Anyway you want
it." Cindy offered.  
  
"You're too good to be true. Anything I want?" Mike teasingly challenged his
daughter.  
  
Cindy rolled off her father and got on all fours waving her ass at him. Cindy
raised her butt into a half kneeling posture. She stared at her daddy while
she sucked the middle finger of her left hand into her mouth. When it was wet
enough she drew a shiny line down her body to her back door. Gently spreading
her ass cheeks she wet the puckered hole of her ass and probed her fingertip
in ever so slightly.  
  
"I think you I know what you want daddy," Cindy teased.  
  
"Oh yes I want to be in your ass?" Mike said excitedly.  
  
"Oh yes, Daddy. Do it here. Fuck my ass with your lovely cock. You know you
want to. And I want you to," Cindy pleaded  
  
Smiling Mike knelt behind her on the bed. Cindy cooed and encouraged him while
she smeared her juices from her pussy to her ass to lubricate it in readiness.
The large purple head of his dick prodded his sexy daughter's asshole and slid
across the puckered entrance. Mike first slid his thick cock deep into her
cunt to get it moist with her natural juices. Cindy groaned aloud as her pussy
was still very sensitive from the recent fucking. Mike made a few slow strokes
and watched as Cindy poked her finger ever deeper into her bum hole. Soon she
was knuckle deep and Mike's prick was slick with her pussy cream. Extracting
her digit she looked back and smiled at her father.  
  
"I'm ready now," Cindy cooed.  
  
Mike eased his big cock from her pussy and trailed it up to her bum. Cindy
positioned the cock head against her hole and pressed back with her body. Mike
matched her movement with a gentle forward push. The very tip of his cock
started to enter her tight hole. Cindy's face was a picture of sexy
concentration, her brows pinched and her mouth drawn tightly shut. The big
cock eased slowly into her back passage. She relaxed her muscles and slowly
welcomed her father's tool into her most private place. Eventually it is in
all the way to the hilt and Cindy looked back at her father and smiled  
  
"Are you okay baby?" Mike asked concerned.  
  
"Yes! Fuck me but do it really slow," She requested.  
  
She clearly loved the solid feeling in her ass. Cindy rubbed her clit, which
served to drive her to another orgasm. There was sweat on both their bodies as
Mike held his daughter's waist and slid his dick in and out of her now gaping
asshole. He was admiring her ass and he couldn't believe that he was fucking
his daughter's ass again.  
  
Cindy's attentions on her pussy were having the desired effect and she was
nearing another orgasm. She hoped that they could climax together so she told
her dad she was going to cum.  
  
"I am too baby, very soon," Mike strained to talk.  
  
His pace quickened again and he changed to shorter faster strokes. He was
pumping her hole telling his daughter that he would soon cum. She was gasping,
grunting and straining toward her own orgasm. Faster and faster her fingers
flew over her clit. Her body started to convulse with a powerful orgasm. At
the same time Mike came, he jammed his cock into her ass to the hilt and felt
it as it jerked and spewed his spunk deep into her anal passage. He fell
forward on top of his daughter with his cock still buried in her and still
twitching and spitting its cum coating her anus.  
  
Cindy's orgasm matched her daddy's in length and fury. Surge after surge of
pleasure shot through her body and each new wave was triggered by each new
twitch from her father's exploding cock. The two of them lay together and
cuddled on the bed with her father's cock still twitching in her ass.
Eventually Mike went soft and his cock slipped from his daughter's curvy ass.
The two of them stayed in bed for another hour caressing and playing with each
other. They would have to figure something out so that they could somehow
continue their incestuous affair but for now they enjoyed their time together.

        Aliens Use Sex to Invade Humans Ch. 05-07


_Author's note: I received an e-mail requesting that I write a story about
aliens taking over humans and creating insatiable sexual desires. The person
requesting this story had read another story on Literotica entitled Hosts. He
was disappointed that the author of Hosts did not write any more chapters
after the first submission, which is why he asked me to write about this
topic. This is the final chapter in this series.  
  
INTRODUCTION

hosts who use human sexual desires to re-populate their alien presence. The
crew is returned to earth and after being briefed by the space agency they all
return to their former lives. The alien's continue to use their human hosts to
recruit other humans through the exploitation of sex.

**CHAPTER 05 - CARL'S FIRST VISIT A GAY BATHHOUSE**  
  
Carl had never been to a gay bathhouse but he had heard about them and he knew
what went on there. The alien in his body picked up on Carl's thoughts and
directed Carl to go to the bathhouse. That Friday evening Carl made his first
ever trip to the bathhouse and it was a night for all to remember. When Carl
entered he paid a fee for a locker opting not to take a room. He stripped off
his clothes and walked brazenly around the bathhouse without wrapping the
towel around his waist. Carl looked better than he ever had in his life since
the alien took over his body. He was lean and trim and his cock was longer and
thicker than it ever had been.  
  
Carl noticed that there were men all ages, sizes and shapes at the bathhouse
and that many eyes were focused on him. Carl walked into an area where a large
number on men milled around playing with each other's cocks and asses. Within
seconds there was a hand on Carl's cock and minutes later his cock was in the
mouth of a middle aged man. As Carl was sucked off a younger man fairly well
endowed stepped up behind Carl and slipped his well oiled cock into Carl's
ass. At that point the alien in Carl's body took over and minutes later Carl
was cumming in one man's mouth while his ass was filled with another man's
cum.  
  
The alien entered the two bodies attached to Carl, one through the mouth and
the other through the penis. The two men immediately felt the change in them
as the alien took over two other hosts. Carl moved on and he spotted a very
shapely ass on a young man who had a less than average size cock. Carl moved
in close and slipped his cock into the shapely ass. The young man groaned as
his rectum was stuffed with Carl's big stiff cock. Carl fucked the young man
hard and fast and then ejaculated into the tight asshole. The young man felt
the large load fill his rectum and he groaned loudly. Carl held the young man
to him tightly as he ejaculated and allowed the alien to enter the young man's
body.  
  
The young man felt his body change as Carl held him tight and filled the young
man with semen. The young man could not believe the change in his body as he
muscled up and his cock grew in size. The young man watched in amazement as
his cock stiffened into an erection that was at least 9" long and 5" around.
He could not believe that it was his cock attached to his body. Carl then
released the young man and moved on to find other prey. The young man looked
at Carl and noticed that Carl's cock didn't go soft. The other two men that
had sex with Carl also maintained erections as they moved about the bathhouse.  
  
Carl walked into the sauna area and within minutes he had a cock in his mouth
and one in his ass while his cock was sucked by another young man. As Carl was
occupied in the sauna the other three alien controlled men had entered the
orgy room with their 9" erections and they were immediately set upon by a
group of men. Back in the sauna the alien was passed from Carl's body to three
other men. The four of them sucked and fucked for several minutes before they
all ejaculated. Then the three other men sensed the change in their bodies and
watched in amazement as their cocks stayed hard and grew in size.  
  
By now there were at least eight men walking around with 9" cocks and Carl's
reputation had spread throughout the bathhouse. Everyone who had come in
contact with Carl experienced a change in their body. They all became thinner,
fitter and well endowed. As the night wore on more and more men were
infiltrated by the alien and became a host for the visitor. That night no one
left the bathhouse as everyone stayed until the sun rose. By the time morning
arrived everyone in the bathhouse had been changed forever. Even the
attendants had gotten in on the action and they too had engaged in sex and had
been taken over by the alien.  
  
The news spread quickly among the gay population and soon they were all
flocking to the bathhouse. Within weeks every gay person in town had become
fitter and well endowed. Sex at the bathhouse became rampart and its
reputation spread quickly. Soon other gays from nearby towns came to spend a
night in the bathhouse. The orgies became notorious as more and more gays
participated in them. Then they would return home and populate their local
areas with the aliens.  
  
As the word got out several agencies including the space agency began to
investigate the strange phenomena. The space agency quickly recognized that
the four astronauts were heavily involved in the phenomena and that they might
even be responsible for it. The agency then decided to keep a close watch on
the former astronauts in their public life. They had already summoned Carl
back to headquarters where they planned to run some tests.  
  
CHAPTER 06 -- SAM RETURNS TO PRIVATE PRACTICE  
  
While the space agency was working on Carl's tests they also kept a close
watch on Rachel, Aaron and Sam. The agency knew that Sam had returned to
private practice so they observed his patient population. Sam had opened his
office in his home town and soon had patients coming to see him for routine
medical care. Just the presence of so many naked bodies both men and women
were fertile hunting ground for the alien.  
  
Sam hired a young attractive girl as his receptionist and another young woman
as his nurse. Sam's first mission before he began to see patients was to
seduce the two women and pass the alien on to new hosts. The receptionist was
a pretty blonde 19 year girl named Pam. She had a nice figure at 34-23-35. She
was about 5'7" tall and weighed a fit 105 pounds. The nurse named Melanie was
a little shorter than Pam at 5'5" and she weighed in at 100 pounds. Melanie
had bleached blonde hair and she had a cute 33-22-33 figure.  
  
Sam driven by the alien was immediately attracted to both women and he was
anxious to fuck them both. Melanie who was a single mom and needed the job was
the most vulnerable and she seemed willing to do what ever it took to keep her
job. One evening during the week that they were moving into the office, Sam
asked Melanie to stay late and help him with some things. Sam purposely had
Melanie put his medical books away and when Melanie stood on the ladder to
reach the top shelf, Sam made his move. He smiled as she leaned forward and
her white skirt rode up to just below her ass cheeks displaying her beautiful
legs encased in the white hose. Sam closed and locked the office door behind
him. He walked over to the ladder and gripped it with both hands.  
  
"I'll just steady this for you so you don't lose your balance," Sam startled
her.  
  
"Oh I didn't hear you come in, I'm okay you don't have to hold the ladder,"
Melanie embarrassingly replied.  
  
"No problem at all," Sam said.  
  
He looked up the ladder following Melanie's shapely legs up to her panties
visible under her short nurse's skirt. Melanie knew that he could see up her
skirt and there was nothing she could do about it. She placed the last of the
books on the shelf and began her descent down the ladder. As she descended
rung by rung, Sam fixed his eyes on the gap between her legs and her panty
covered pussy. Melanie was beat red and she gasped out loud when she felt
Sam's hands on her legs.  
  
"I'll just steady you as you come down," Sam said as his hands slid up her
calves.  
  
Melanie was trembling and as she stepped down Sam's hands continued to slide
up her legs. Sam's hands had moved over her calves to the back of her knees
and then up to her thighs to her bare skin. One more step and Sam's hands
moved under her skirt and covered her panty covered ass.  
  
"Please don't" Melanie weakly protested.  
  
She felt Sam slide his hand over her pussy mound and she trembled slightly.
She realized that her panties were getting wet just as she heard Sam speak.  
  
"Your panties are very wet we should probably take them off so they don't get
stained," he offered.  
  
Sam peeled her panties off her ass cheeks revealing her beautiful ass. He then
pulled them from between her thighs where her legs were pressed together and
down to her ankles. Sam had her lift up one foot at a time so that he could
remove her panties from her ankles. He slid his hands back up to her ass and
massaged it gently complimenting her on the beauty of her legs and ass. Sam
slowly turned Melanie around on the ladder so that she faced him. He guided
her down a few more rungs pushing her skirt up and exposing her blonde pussy.
Sam tenderly stroked Melanie's cunt and slipped a finger into her hole. He
tweaked her clit and Melanie grasped the ladder to stabilize herself. Her cunt
was soaking wet and she knew that she should call a stop to this but she was
afraid it might cost her to lose her job. Melanie decided to let Sam have his
way with her.  
  
Sam pulled her hips forward and kissed her abdomen. Melanie shivered and
trembled as she locked her arms behind the ladder to maintain her balance. Sam
kissed all around her pussy before licking her clit and inserting a finger
into her cunt. Melanie was going wild as she humped Sam's face with her cunt
and he ate her to multiple orgasms. Sam had both hands on her ass as he ate
her pussy. The last orgasm caused Melanie to let go of the ladder and she
found herself being carried to her desk. Sam laid her on her desk with her
legs splayed wide.  
  
Melanie watched as he unbuckled his pants and pushed his pants and underwear
down to his knees. His huge cock jumped out and Melanie gasped in surprise of
its size. Sam lined up his impressive tool with Melanie's quivering twat and
eased it in. Sam took his time and kept feeding her more and more of his cock
as he fucked her slowly.  
  
Melanie was beside herself as she felt her cunt being methodically stretched
to accommodate his length and girth. There was no pain but Melanie had never
felt fuller in her life. Sam continued to fuck her slowly and soon had the
entire 9" buried in her pussy. He made sure to keep his cock in constant
contact with her clit and kept her in a constant state of arousal. Melanie was
thrashing all over the desk having multiple orgasms. She felt Sam tense up and
bury his cock to the hilt in her pussy. He then fired a barrage of cum into
her hot pussy and she could feel warm jets of cum hitting the walls of her
cunt.  
  
The surge of his hot seed caused her to have yet another orgasm. Sam continued
to fuck her slowly as they both recovered from their intense orgasms. He
slipped his cock from her and remarkably he was still erect. Melanie felt the
void in her cunt as his cock left her opening and she could feel his cum
trickle down between her thighs. Then she also felt a strange sensation run
through her body. Melanie was unaware that the alien had entered her body but
she knew something was different. She suddenly felt younger and fitter and her
tits strained against her small bra.  
  
Sam turned Melanie around so that she was facing down on the desk with her
feet on the floor. He eased his still erect cock back into her pussy and
fucked her with long deep strokes. Sam pulled her blouse up and unsnapped her
bra allowing her tits to spill out into his hands. He gently squeezed her now
firm tits and played with her eraser sized hard nipples.  
  
"You have the neatest, hardest little nubs," he said as he rolled her nipples
in his fingers.  
  
Melanie was getting turned on again as he fucked her and played with her. She
was startled and her body went stiff when he inserted a well lubed finger in
her asshole. Melanie thought to protest but thought better of it and after all
it was just a finger. Sam's hands left her tits and he continued to finger
fuck her ass as he fucked her pussy. With his other hand he began to tease her
clit and soon had her on the verge of another orgasm. Melanie grunted and
groaned as Sam fucked her with his big dick, tweaked her clit and reamed her
asshole with his finger. She started bucking out of control while having her
most intense orgasm ever.  
  
Sam took advantage of her orgasmic state and slipped his cock out of her cunt
and re-positioned it in her ass. Melanie's thrusting and Sam's continued
pressure allowed Sam's cock to enter her asshole. By the time Melanie realized
what had happened, Sam had buried the entire 9" in her ass. Melanie was now
impaled on his cock and for the first time in her life she was being fucked in
the ass. She couldn't understand why she was receptive to such a taboo act but
now that she was a host for the alien she had no control of her actions.  
  
Melanie just felt full now as any initial pain had subsided. She tried to
relax and let him has his way with her. Sam continued to diddle her clit with
one hand and tweak her tit nipples with the other as he corn holed her
gorgeous ass. Sam loved watching his huge meat slide in and out of her bung
hole. He felt another orgasm on the way and buried his cock to the hilt.
Melanie could feel his hot cum filling her anal canal to overflowing.  
  
As Sam finished shooting his wad he let his softening cock slip out of her
asshole. It left her ass with an audible pop and Melanie could feel the cool
air enter her channel. She could also feel his cum leaving her asshole and
trickling over her cunt lips. She had collapsed on the desk in front of her
and was breathing deeply as Sam massaged her ass cheeks as he took in her
beauty. Melanie's ass was still clenching as she worked her anal muscles
involuntarily and subconsciously ejected his cum from her asshole.  
  
Melanie then suddenly wanted to be naked so she stripped off her nurse's
uniform and stood naked in the office. Sam then stripped off all of his
clothes and as he did Melanie checked out her body in the mirror. She liked
what she saw although she did not know how or why her body had changed. Then
she spread out over the desk again and beckoned Sam to her.  
  
"Fuck me again," she pleaded this time.  
  
"My pleasure," Sam said as he moved between her legs and slipped his still
hard cock into her pussy.  
  
PAM IS NEXT  
  
Sam and Melanie fucked for hours that first time and since then Melanie seemed
to be horny all the time. They would fuck each day after work and pleasure
each other. Still, Sam was driven to seduce Pam and fuck the teenage
receptionist. One day Sam invited Pam to dinner where he made sure that she
had plenty of wine. After dinner Sam brought Pam back to his house to seduce
her. Once in his home Sam led a tipsy Pam into his bedroom.  
  
Sam led her over to the bed and hiked her dress up around her waist. He
maneuvered her onto the bed and whispered in her ear that he was going to play
with her ass. He then removed Pam's panties pulling them off her buttocks
slowly as if he were unveiling an art masterpiece. He placed a pillow in front
of Pam so that she could place her head on it and as she did she pushed her
ass up and arched her back. The giddy Pam was now eager to be pleasured.  
  
Before Sam began the seduction he stood behind Pam and took in her marvelous
ass, so round, so shapely and so beautiful. Then as Sam knelt on the bed he
noticed Pam's face aglow and her eyes wide in anticipation. Sam then began to
explore her ass as he began to caress it, massage it and rub her cheeks. He
pulled her cheeks apart slightly and revealed her sweet tight aperture. Then
he ran a finger over her sensitive little bud and watched it quiver when he
touched it. Sam then lowered his head and planted soft tender kisses all over
her buttocks. Pam cooed aloud when she felt his lips on her backside.  
  
Sam placed both hands on her ass and began to massage her buttocks again. Pam
felt the tender but firm deep massage of his fingertips. Sam would push her
ass cheeks together and then pull them apart to expose her sweet asshole each
time. When he exposed her anus, Pam could feel the cool air on her rosebud.
Sam again lowered his mouth to one of her buttocks and pressed his lips
against it. Then he blew a steady breath onto Pam's anus and watched as goose
bumps covered her skin. He took his time planting well placed kisses on her
buttocks and then began a slow torturous journey toward the crack of her ass.
Pam smelt so nice and so fresh. Sam's lips then came into contact with the
crack in her ass and trailed a line of kisses down to her anus. Pam's body
tensed as she was nervous, anxious and excited all at the same time.  
  
Sam gently pried her cheeks apart wider exposing her nether hole even more.
Then he lowered his lips to her anus and gently kissed it and caressed it with
his lips. He repeated this act several times and Pam moaned aloud as her ass
was pampered for the first time. Sam then moved lower and kissed the sensitive
spot between her asshole and her pussy and Pam groaned again. He then extended
his tongue and lightly licked the sensitive area as he continued the journey
toward her pussy. Pam flinched at the first contact with her pussy as she was
unprepared for that. Sam then began to lick a line from her pussy back to her
asshole and then he flicked his tongue across her nether hole. Pam's body gave
in to the incredible erotic sensations and craved more attention.  
  
Sam took his time and spent many minutes repeating the actions that seemed to
turn Pam on. His hands continued to massage her fabulous globes while his lips
and tongue explored her asshole. Pam realized how much she like to be kissed,
licked and gently nibbled. Her body would twitch and flinch at the long
strokes from his tongue and her buttocks would tighten when his tongue probed
her anus.  
  
Pam lay on the bed and she could feel her heart racing and her chest pounding.
Sam then leaned over and whispered to her again and told her how beautiful she
looked with her ass pushed up high in the air. Then he began to explore her
with his fingers. He placed his index finger on her tailbone and slid it down
ever so slowly toward her puckered asshole. He probed gently with the tip of
his finger and it fit perfectly in the entrance of her tight hole.  
  
Pam tensed up at first and tightened her ass but then she relaxed when she
realized that he was going to be gentle. Sam pressed his finger in gently
applying a little pressure as his finger entered the outer edge of her anus
entering it just ever so slightly. Then he probed a little deeper and wiggled
inside Pam's ass. He then removed his finger and Pam felt its absence. Then
she felt a cool substance on her anus and she realized that Sam had applied
some sort of lubricant to her ass.  
  
Pam felt Sam kiss her ass cheeks again and then his finger returned to her
asshole and spread the lubricant around the entrance. Pam felt her asshole
pucker up as it received the tip of Sam's finger and she wondered how it would
feel when he finally put it in her. Her body ached with desire and she
realized that she wanted more. She wanted to be touched, penetrated, and
filled up and to be explored in her forbidden area. Sam's finger slid in
deeper and Pam instinctively clamped her asshole around his finger. Sam held
still in her and waited for her to relax before probing deeper.  

Sam then wiggled his finger back and forth and let it slide out slowly to the
first knuckle. Pam felt his finger slide out and she instinctively clamped her
ass around it again, this time to hold it in place. Sam could feel her anal
muscles clench his finger as if she were milking it and nursing it. Sam knew
the battle that was going on within her body. The sphincter was designed to
push things out not pull them in. Each time Pam relaxed her asshole, Sam
pushed his finger in deeper until she clamped around it again. This process
continued until he entire finger was buried in Pam's ass.  
  
With his other hand Sam continued to pay attention to the rest of her ass. His
hand wandered all over her shapely buttocks massaging and caressing her soft
skin. At the same time he continued to slide his finger in and out of Pam's
asshole and he enjoyed watching her anal muscles grip his finger each time.
Pam's breathing had become labored and she began to rotate her ass in tiny
circles as if to get the finger in deeper. Sam was in no rush as this is
exactly what he had planned. He wanted Pam to enjoy every moment of the anal
sensations. He wanted to work Pam into a state that she would beg him to fuck
her ass or her pussy or both. For now though he was content to worship and
devour her hot luscious ass.  
  
Sam then lowered his face to her ass and licked her as he probed her with his
finger. He took his other hand and reached under her to find her pussy and her
clit. As soon as Sam made contact with Pam's hot wet pussy her body trembled
as a wave of pleasure passed through her. Sam was very skilled at finding a
woman's g-spot and he located Pam's instantly. Between on finger rubbing her
g-spot, another diddling her clit and a third finger in her ass, Pam groaned
loudly and her body shook with desire. She knew that she was close to her
first orgasm.  
  
Sam's two fingers in her pussy matched the rhythm of the finger in her ass Pam
could feel all the fingers in her separated only by a thin membrane inside
her. Sam pumped his fingers in and out and Pam went wild. Sam could feel her
body giving itself over to him. It was his now to do as he wished. Her pussy
was dripping wet, her ass clamped tight around his finger and her hips pushed
back at him but Sam did not want her to explode just yet.  
  
Sam suddenly removed his fingers from her holes leaving her empty. Pam
screamed for him put them back in her, to fill her up again. Her eyes were
wide open and she had a wanton look on her face. Her body was begging to be
fucked but Sam was in no hurry. He enjoyed this moment and he savored her
dilemma. Sam loved doing this to a woman, teasing her and prolonging her
climax. He wanted Pam's anticipation to last as long as possible.  
  
Sam then lowered his lips down to her hot ass and planted kisses all over it
again. He massaged the smooth white flesh of her ass as he kissed it and Pam
cooed. She longed for his fingers to be back in her. Sam moved his mouth
directly over her anus and blew on her nether hole. Pam thrust her ass back
into Sam's face as if to impale her ass on his tongue. Sam needed no further
encouragement and his hands spread her ass open wide so he could probe her
asshole. Sam stiffened his tongue like a tiny dick and probed Pam's asshole.
He poked his tongue in and out of her ass then he covered her ass completely
with his mouth and sucked hard on it. Sam began to lick, nibble and tickle the
sensitive rosebud and Pam cried out in passion.  
  
"Are you ready to cum, Pam? Do you want me to make you cum?" Sam teased her.  
  
"Oh God yes, please make me cum, let me cum," Pam screamed back.  
  
It was the first words they had spoken in over an hour. Sam then reached under
her again and located her clit. Pam's pussy was sopping wet and Sam knew she
was very close to a climax. He played with her puffy pussy lips as she diddled
her clit and then he pushed first one, then two and finally three fingers into
her pussy. Sam then pulled his mouth off her assed and pushed two fingers from
his other hand into Pam's snug asshole. Pam gasped and swallowed hard at the
new invasion in her ass but her state of desire and the lubrication
facilitated the extra digit.  
  
Sam now had three fingers in her pussy and two in her ass as he picked up the
rhythm. The thrusts became deep and hard as he relished with the delight of
devouring her ass and pussy with his fingers. Pam responded by pushing her ass
back against his hands as she fucked back at them.  
  
"That's it Pam, fuck back, fuck my fingers in your holes," Sam called out to
her.  
  
Sam finger fucked her two holes with both hands as Pam pushed back against
him. He could feel the small patch of skin separating the three fingers in her
pussy from the two in her asshole. Sam was getting carried away and he began
to furiously fuck her lovely hungry body with his fingers. Then it happened
and Pam exploded. She clamped down on the fingers in her body and her pussy
spasmed as a massive orgasm rocked her. Pam screamed out loud with her mind
blowing climax. Sam pulled his fingers from her asshole and replaced them with
his mouth.  
  
He could feel the hot moisture in Pam's pussy as it coated his fingers. Sam
continued to lick her quivering asshole as her first orgasm subsided but hen
another orgasm rocked Pam's body. This one seemed even more intense than the
first and it caught them both by surprise. Sam kept his mouth on Pam's ass
until the second orgasm had passed and she seemed to recover. With one last
kiss on her cute little rosebud, Sam lifted himself up and looked at the
beautiful Pam. She had her head turned to one side on the pillow with a look
of pure lust and gratitude in her eyes.  
  
Sam then stood up and removed all his clothes and for the first time Pam saw
his cock and she was intimidated by the size. Sam moved around the bed and
removed Pam's clothes so that she was completely naked now. He gently squeezed
her big tits and tweaked her hard erect nipples as he complimented her on her
figure. Sam had Pam remain in the same position on the bed and then he
caressed her curvy ass again.  
  
"I want to fuck you in the ass Pam. Do you want me to fuck your hot ass? I can
see that your ass is asking to be fucked."  
  
"Sam, I'm not sure, it's not right," Pam said nervously but she knew she had
come this far and Sam would not take no for an answer.  
  
Sam poured more lubricant on her ass and worked it into her asshole. Pam
arched her back and pointed her beautiful ass back at him. He coated her
asshole with a generous amount of oil and slid his thick finger back in her
hole. He took his time preparing her ass relishing every moment. He then
coated his entire cock with the oil and placed the head at the entrance to her
anus. Sam pushed forward and the thick cock head squeezed into Pam's tight
asshole.  
  
Sam withdrew his cock head and then pushed it back in this time causing more
pleasure than pain. He pushed until a couple of inches were in her ass. Pam
found her self holding her breath and her body was covered in goose bumps. Sam
was so thick that her asshole stretched to new dimensions and held his cock in
a vice like grip. Sam slowly slid his dick in and out of her each time going a
little deeper. Pam pushed back as if she were trying to poop as she knew that
would make the penetration easier. Pam's brief pain had subsided and it was
replaced with a feeling of fullness.  
  
Pam relaxed a little and then felt more of Sam's cock slide into her asshole.
She grunted out loud as she felt fuller and then a wave of pleasure passed
through her body. She was convinced that Sam had his whole cock in her now but
really he only had about half of his big dick in her. She felt so full so had
no idea that he had about another four inches before he was done. Sam kept
adding more and more of his cock to her ass. There was discomfort then
fullness and then pleasure each time he went deeper. Pam would tense, relax
and then enjoy it. This pattern continued until Sam had his whole cock buried
in Pam's ass.  
  
Sam reached around and played with her clit as he pounded her ass. Her pussy
and asshole were on fire as the big cock reached previously untouched areas in
her body. Pam was on the brink of another huge orgasm as Sam methodically
fucked her in her tight anus with his sizeable cock. He loved watching his
cock slide out of Pam's shapely ass and then plunge back in as his hips
slapped against her curvy ass cheeks causing them to jiggle with each thrust.
Her orgasm surged within her as he fucked her ass harder and faster.  
  
As Pam came and came her entire body went into spasm. Her pussy convulsed and
clamped around Sam's fingers coating them with her cunt juice. Pam's asshole
pulsated as Sam drove his big cock in and out of it. Her ass involuntarily
squeezed and released his huge member as he fucked it causing him to finally
lose it. Sam slid his pecker deep into Pam's rectum as his cock spasmed and
sent a thick stream of hot cum into her channel. Sam kept fucking her as load
after load was fired into her ass. His cock kept twitching and spurting inside
the impaled Pam.  
  
Pam had never felt so full of cum and there was no where for it to go, blocked
by Sam's swollen cock buried in her ass. He slowed his pace and eventually
stopped allowing his cock to remain buried in Pam's ass. He did not go soft
right away and he gently moved his hips pushing cum around in her ass. Some of
it trickled out and ran down over her pussy lips. Pam then felt a strange
feeling that something was happening to her body. Her tits all of sudden
seemed firmer and there was a fire in her pussy.  
  
Sam stopped and slowly withdrew his cock from her loosened asshole. He
marveled in the sight of his impressive cock sliding out of Pam's shapely ass.
His man seed flowed from her asshole and ran like a river down over her pussy
and between her sweet thighs. Sam and Pam stayed in the same position for
awhile and he massaged her beautiful ass as she remained on her knees with her
ass perched in the air. Sam pushed down lightly on Pam's back causing her to
accentuate her ass even more. He loved looking at it and playing with it as
she cooed into the pillow. Sam's cock remained hard and looked menacing around
Pam's asshole. He was thrilled that he finally fucked her beautiful tight ass.
Pam looked magnificent with her just fucked curvy ass in the air. Sam could
not resist sticking one of his fingers in her asshole and she just wiggled her
bum instinctively.  
  
Pam then rolled over on her back and Sam moved between her legs. Sam slipped
his still hard cock into Pam's pussy and they fucked like rabbits. Pam had
countless orgasms and Sam ejaculated in her pussy numerous times. Then Sam had
to have Pam's ass one more time and she willingly moved back to all fours. Now
that the alien possessed both Pam's and Melanie's bodies, Sam would focus on
his patients. Pam and Melanie would assist in the seduction of many patients
and the alien population would continue to spread.  
  
CHAPTER 07 -- THE ALIEN POPULATION CONTINUES TO GROW  
  
The aliens continued to acquire hosts at a rapid pace and they controlled
almost the entire towns where the four astronauts lived. Incest was rampant
among families and the high schools and colleges had daily orgies on campus
with students and teachers. The space agency was now convinced that the
astronauts had returned infected with a strange virus. Carl had been summoned
to the space station for tests and he was under quarantine.  
  
The agency director decided to experiment with some human contact and had
selected a young man from the agency to interact with Carl. Suspicious that
Carl would try to seduce whomever he came in contact with, the director
selected a young effeminate looking man known to be gay. The interaction went
according to plan as the agency team observed Carl and the young man Roger
together.  
  
Roger had expected to conduct an interview with Carl but he had no idea of
what Carl was capable of. Roger was putty in Carl's hands and in no time they
were both naked in the exam room. Carl guided Roger over to the exam bed and
had him kneel down on all fours. Then Carl knelt behind Roger and he began to
caress Roger's beautiful ass. Roger's body was delicate, hairless and
flawless. As he sawed his fingers in and out of Roger's anus Carl was getting
turned on as the alien directed him to bury his cock in the shapely ass. He
moved closer to Roger and lined up the head of his cock with Roger's anal
opening and began to ease it into to him.  
  
Carl spat on his hand and rubbed his saliva all over his cock which made it
very slick. Carl's cock head cleared Roger's sphincter and it slid right in
without resistance. Roger's ass chute was warm and tight as Carl went deep
into him. If Roger ever felt any pain he never let on that he did. Carl was
all the way in Roger's ass and he started a slow fucking motion. Carl
continued to pump Roger's ass with deep, long, deliberate thrusts as he
caressed the smooth round ass.  
  
Roger asked Carl to fuck him harder and quicker. So Carl picked up the pace
and he started pounding Roger's ass faster and faster. Carl's balls started
bouncing off of his Roger's balls and Roger was moaning with each thrust of
cock. Carl could feel his climax building and he knew that any moment he would
shoot his seed in Roger's ass. Carl tried to make it last as long as possible
but once Roger started to contract his anal muscles Carl lost it.  
  
Carl fired a barrage of cum into Roger's ass filling it to overflowing. As he
continued to fuck Roger, Carl's cum backed up in Roger's rectum and began to
ooze out flowing over their balls. Roger used his talented anal muscles to
milk Carl's cock and drain it of all his seed. Carl didn't think that his cock
would ever be soft again as he remained hard in Roger's tight sheath. Roger's
milking action weakened him and Carl collapsed on top of Roger's body.  
  
Roger flattened out on the bed with Carl on top and Carl's cock still in his
Roger's ass. Carl rolled off of him and his hard cock slipped from Roger's
ass. Roger rolled to his back and spread his legs lifting his knees to his
chest. The alien had now entered Roger's body and was in control of the host.  
  
"Fuck me again," Roger begged.  
  
Carl moved between Roger's legs much like he would fuck a woman and lined up
his still erect cock with Roger's asshole. Roger was also as hard as a rock
and his beautiful cock pointed toward his head. Carl pressed slightly forward
and his cock moved into Roger's hot ass again. Roger's ass actually pulled
Carl inside and the cock went all the way into Roger's ass as Carl's balls
rested on Roger's ass. Roger than gasped in surprise as he felt his body
change and he watched his cock grow right in front of his eyes. Roger stared
in disbelief at his cock as it grew from his average 6 inches to a thick 9
inches. The agency team also watched in awe as Roger's body changed right in
front of them.  
  
"God, that feels so good, fuck me," Roger cried out.  
  
Roger's ass lifted off the bed and Carl's cock was fully embedded in it. Carl
pulled back a little and pushed forward. Roger groaned as Carl began to slowly
fuck him, each time taking a longer stroke. Carl's cock head would come out to
the edge of Roger's asshole before he pushed it back in. Their fucking was
making a sucking sound. Each time Carl's balls slammed against his nurse's
ass, his body and Roger's ass made a wet slapping sound.  
  
Carl was so fucking hot that he crammed his cock fully into Roger. Roger held
Carl's cock and massaged it with his anal muscles; Carl knew he was not going
to last very long even though he had already cum. Roger humped up against Carl
fucking him back as Carl fucked him. Their room smelled of sex and sweat. Carl
reached down to stroke Roger's cock but Roger grabbed his wrist.  
  
"No, I want to cum just from you fucking me," he said and pushed the hand
away, "Just keep fucking me."  
  
Carl took slow long strokes in and out of Roger's ass as Roger pushed up into
him more and more. Soon Roger took control and just fucked Carl's cock. Carl
let Roger fuck him with his ass muscles. Carl's actions became more erratic
and his thrusts shorter and more powerful. Roger was grunting as Carl's cock
slid in and out of his hot ass. Soon Carl's cock was barely staying in Roger's
ass. Then Roger slowed down and let the cock just press against his prostate.
Roger announced that he was cumming. Carl felt Roger's cum shoot between their
bodies covering their chests and abs and then oozing out around their pubes.
Carl slammed his cock into his Roger's loose wet hole and he felt his balls
tighten again. Carl pressed deep into him and his seed filled Roger's ass.  
  
"Yes cum in my ass again. Oh I feel it, I feel your hot juice," Roger groaned.  
  
Carl pulled, pushed and cum spurted into Roger making his hole wetter and
warmer as Carl's cock easily slid in. Carl continued fucking him until his
legs were weak and he stopped cumming. Carl's cock slipped from Roger's ass
and remarkably they were both still hard. The agency observed the action
between Carl and Roger as the two men seemed insatiable and fucked for hours.  
  
The agency had part of the answer now as it was confirmed that the virus was
transmitted by sexual intercourse. Now that they knew how it was spread among
humans they had to figure out how to kill the virus. The rest of that day they
would put their heads together and try to determine how to deal with the alien
virus.  
  
THE SPREAD OF THE ALIENS IS SOLVED  
  
Sam and his assistants, Pam and Melanie had been successful in seducing both
men and women and spreading the alien to new hosts. Pam and Melanie had no
trouble seducing the male patients who loved fucking the hot women and loved
the change in their bodies. The male patients would go home after the doctor's
visit and they would fuck their wives, girlfriends and daughters spreading the
alien to more and more hosts.  
  
Sam was successful seducing many of the women patients and they loved the
change in their bodies. They too would return home and fuck their husbands,
boyfriends and sons also spreading the alien population. A few times Sam
encountered a gay patient but he had no trouble getting the patients to suck
his cock or accept his cock in their asses.  
  
The population was getting fitter and hornier every day. The women were
looking beautiful with their firm bodies and perfect shapes. The men were
fitter and they were all well endowed and had developed an incredible capacity
for sex. The space agency then called Aaron, Sam and Rachel back to
headquarters and quarantined them so that they could be observed.  
  
The team studying the issue closely determined that prolonged exposure to the
sun might just be the solution so they arranged a test case. Carl was escorted
to the beach accompanied by a handsome young man named Fred. As they sat on
the beach the alien began to take control and directed Carl to seduce Fred.
Carl began to make advances toward Fred who was not gay. Fred tried to avoid
the advances but Carl was insistent.  
  
At one point Carl whipped his swim suit down to his knees and his big thick
nine inch cock sprung out. Fred moved away but Carl jumped on him, pinned him
to the sand and ripped Fred's bathing suit from his body. Fred screamed for
help as Carl tried to shove his cock into Fred's ass. However with his anus
dry and taut, Carl could not penetrate Fred's asshole. Carl then reached for
the suntan lotion to use it to lubricate Fred's asshole but as he did Fred was
able to break free.  
  
Fred ran into the ocean as he was an excellent swimmer. Fred's swimsuit fell
from his body as the naked Fred dashed into the water. Carl grabbed the lube,
kicked off his swim suit and chased after Fred. The onlookers were shocked to
see the two naked men running toward the ocean particularly with Carl's big
dick bobbing in front of him. Fred had cleared the breakers and was swimming
steadily away as Carl hit the water. Carl cleared the breakers and then his
body went limp.  

All of a sudden Carl had no energy and he felt his body change. He started to
feel ill so he turned back and left the water. Carl then realized that his
body had returned to its original form before the alien had taken over. His
cock shriveled and became soft as it returned to his average size six inches.
His paunch reappeared and he definitely felt older and out of shape. Fred
stayed in the water and watched as the change came over Carl.  
  
Just then the authorities arrived to arrest Carl and Fred for nudity on a
public beach. The two of them were taken into custody and transported to the
local police station. Fred notified the agency about what happened and where
they were being held. Representatives from the space agency arranged for Fred
and Carl to be released into their custody and returned them to headquarters.  
  
To assure that it was not an isolated case the agency had Aaron, Sam and
Rachel exposed to sea water. The results were the same as the three astronauts
also returned to normal. The agency then put a task force together and
arranged for all areas known to be exposed to the alien virus to be treated
with pure and simple seawater. In time all populations returned to normal and
the alien virus had been eliminated.  
  
The agency would then make sure that all astronauts returning from the space
station would be decontaminated with seawater along with the normal procedure.
It had been quite a scare for the agency and the populace. Who could ever
imagine what the planet would have become if a cure had not been found? Would
have the people been happier with fit bodies, big cocks and insatiable sexual
appetites? We will never know.
