Aliens Use Sex to Invade Humans Ch. 04

by walterio

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.
