Under Watchful Eyes Ch. 02

by AsylumSeeker

Author's Note: I hope readers take the time to peruse Under Watchful Eyes, which was written from the parent's perspective during the same time frame and is posted in the Loving Wives category. I think it might be fun, having read this, to know what's going on in the background. I tried linking the two stories with commonalities that you should recognize.

"Dad, what do you mean I have to sleep with her?" Tim angrily called out from the back seat. "She's my sister!"

His father's shoulders sagged, and he sighed. "We both know we couldn't find the tent. I have no idea where it is, and neither did you. If you're that opposed to the idea, then you're welcome to sleep in here."

"The truck?"

"Or you can really rough it and sleep outside."

Tim rolled his eyes while folding his arms across his chest.

"Oh, what are you bitching about?" Chrissie asked. "I'm the one that should be complaining! Do you actually think I want your hairy, greasy, bug-bitten skin touching mine? Yuk! If we do have to sleep together and anyone ever finds out, my social life will be, like, totally destroyed!"

Tim glanced over at her and made a face. "Believe me, I won't be telling anyone!"

He remained angry and just sat there, staring out the right passenger window. Yet while he wanted everyone else to think he was looking at the scenery, he was instead admiring the reflection of his sister. The front of her chest was visible, the downward slope of the top of her sexy breasts jiggling with every bump. She was wearing a tight white top that clung to her shape. He could even see the outline of her long nipples as they proudly thrust against the fabric, forming an inviting, pulsating peak.

Tim leaned toward the door, pointing his body away from hers. When he glanced at his parents they appeared to be whispering to one another, and their mom was even licking on Dad's ear. The two were giggling in a disgusting manner and were totally ignoring him, which Tim preferred anyway. His right hand gripped his crotch and began squeezing. He was soon hard.

When he heard Chrissie moving, Tim stopped touching his hard-on. She leaned over toward him while reaching into a travel bag that was resting on the floor of the truck beside his feet. He felt her right breast rubbing against his upper arm as she dug through the contents. Tim couldn't believe one of the boobs he'd been staring at and lusting for was now jiggling against his bare skin. He could even feel the nipple brushing back and forth across his arm. He covered his straining erection as best he could.

"What are you looking for?" he finally asked, embarrassed at how large his cock had grown.

She noticed that her brother had both hands cupped over his crotch. "What are you doing? Hiding something, Tim?" she teased in a whisper only they could hear. "Have you got a chubby? Hmmm?"

Chrissie giggled at him before returning her attention to the bag and whatever elusive item she was looking for. He could've sworn that her nipple swelled once she caught on to his embarrassing condition. The soft boob and long, hard, throbbing tip rubbed on his arm several moments longer before she finally straightened up, holding a memory stick.

"This is what I'm looking for," she finally answered his question.

Tim tried closing his eyes and pushing his sister from his thoughts, but it was impossible. After a few minutes they reopened and he glanced over. She was leaning back with her eyes closed and softly humming along with whatever song was playing in her headset. The red short-shorts she wore left nearly all of her long, shapely, smooth, tanned legs exposed. His eyes scanned her tempting thighs all the way up to her crotch.

He jumped and looked away when she changed position. In his peripheral vision he noticed as she drew her left leg up, placing her foot on the front edge of the bench seat. Her right leg slid closer to him, showing off more of her crotch. He couldn't tell if she realized what she was doing or not. He nervously swallowed and looked over, gazing at her short-shorts.

The legs of her short-shorts were loose, and he could see up her right leg enough to observe the flower-print strip of fabric that hugged her pussy. Tim thought he was looking at a partial outline of her cunt lips, but he wasn't certain. During the shifting, the bottom of her top pulled up, revealing a few inches of her flat midriff, including her belly button and the sexy piercing he so adored. His cock was quickly pulsing with excitement as it pushed the front of his pants outward.

His gaze finally returned to her breasts, which had been the object of so many of his fantasies. He saw them, sort of, earlier that morning. The bathroom door was ajar and he caught her coming out of the shower.

But the glimpse was cut short as she cried out, "Creep!" and immediately slammed it shut. Yet in that endearing moment he finally knew what they looked like, which fueled his imagination even more. His eyes traced up her long, sleek neck to the full lips of her mouth. How he longed to taste them, to snake his tongue into her...

Chrissie's head snapped forward. She looked down, making Tim realize his hand had subconsciously returned to his hard cock and he was squeezing on it through his clothing. A shocked expression appeared on her face. She turned toward her parents in anger, but they were acting all lovey-dovey, so she leaned toward her brother instead.

"Are you staring at me?" she challenged, then added, "Staring at me and beating off?"

Tim's hands immediately covered his bulge. He shrank back and lowered his head in surrender. They both knew the truth of the matter, and he didn't know how to respond. Instead he withdrew; his erection quickly softened.

"You better not do that at night, not when you're in the same bed as me. It's gross!"

He decided she must not have realized how she was sitting gave him such a good view, because when she straightened up she made a point of sitting with her back to him, hiding herself as much as possible from his apparently unwelcome, prying eyes. Tim sighed with relief when it was over, happy she hadn't gotten their parents involved. He had no idea what they would have said or done.

The encounter effectively cooled his excitement. He picked up a book he'd started a few days ago and lost himself in an action-filled adventure.

* * * * *


It was a six-hour drive, and at the halfway point they stopped to stretch their legs, fill up the truck, and get a snack. It was a brief reprieve from the muscle-stiffening confines of the extended-truck cab. Tim walked past the small two year-old pop-up trailer they were pulling and toward the front door of the convenience store. Fifteen minutes later they were back in the truck and on the road.

Chrissie was eating potato chips from a medium-sized bag and held a waxed paper drink cup against her chest. The weather was humid and condensation had formed on the outside of the drink, which soaked into her white top. As she lifted the cup to her lips for a sip, Tim couldn't help but notice that a small patch of her tight top was wet and transparent. The spot coincided with her right breast.

A portion of the perky swell was visible, along with the light pink tip, which appeared to be hard. She was so focused on her chips that Chrissie never even looked over at her brother. Perhaps she was still harboring lingering resentment at him for staring and simultaneously touching himself, but as they stood in line at the counter of the store she seemed civil enough.

While actively trying not to be overly obvious, Tim admired the swollen, dimpled pink areola and the long, hard shaft of the nipple. They seemed to be enlarged and visibly pulsated with every beat of her heart. Maybe it was the cold from the drink that had made it erect, Tim theorized, or was she knowingly teasing him and exciting herself in the process? But if that was the case, why would she have thrown such a fit earlier? Women were so hard to figure out.

Chrissie picked up the bag and reached toward him. "Want a few?"

His eyes narrowed suspiciously. When she saw his reaction, she smiled. "I'm sorry about what I said earlier, okay? Can we just be friends and enjoy this vacation? Consider it a peace offering."

"Okay," he hesitantly agreed.

As he extended his hand he halfway expected her to pull the bag back, but she didn't. The offer, apparently, had been genuine. He reached into the bag, captured a few chips between his fingers, and withdrew.

"Thanks," he told her before putting them in his mouth

"Sure."

"What were you listening to?" he inquired a few minutes later, curious what she'd been humming for the past couple of hours.

She raised a few more chips to her mouth and ate them. As she chewed, Chrissie rapidly brushed her hands together, knocking the salt and crumbs off, and then rolled the top of the bag over several times, saving the rest for later.

After swallowing, she answered, "Hip-hop, rap, a little country... the hits, mostly. I have another headset if you want to listen, too."

He smiled. "I'd like that."

She dug into a small accessories bag and pulled it out, pressing the miniature connector into a second headset port on her music player. "You'll have to get friendly, the cord is pretty short. If not, I'll understand."

Tim quickly nodded his head. "No, I don't mind at all."

They shifted a few items and made room for him beside her. In order to get comfortable Tim had to move his left arm around her, which Chrissie didn't seem to mind. Being that close, he could smell her body mist and apple-scented shampoo, both of which were really nice.

It was strange in a way sitting together, the side of her body up against his. When she lifted the cup to her mouth he had a top-down view of the exposed nipple. Tim tried not to think about it but was inexplicably drawn to the erotic sight. He felt the tingling returning to his balls and his cock shifting as it hardened yet again.

In his mind he was brushing his lips over the swollen nub, teasing it with his tongue. Luckily she lowered the cup, once again hiding the distraction. She pulled her headsets off with an annoyed expression of her face. Tim bristled, halfway expecting her to jump on him again.

"What?" he asked defensively.

"With all this stuff we have in here, my legs can hardly move," she complained. She lifted her right leg and draped it over his left. "Ah, now this is better. Do you mind?"

Tim nervously swallowed. It felt weird having his sister's bare leg resting on his. Even through his clothing he could feel the soft warmth of her skin. The shift of limbs also left her crotch open to his prying eyes once more.

"No, that's fine," he assured her.

"You can rest your hand on my leg if it's more comfortable, I don't mind. I'm going try and see if I can maybe take a nap. But if I do fall asleep, don't turn the music off."

"No, I won't," he readily agreed.

She finished off her drink, placed it on the floor, and then seemed to notice the transparent wet spot for the first time. Her fingers helplessly brushed at it.

Chrissie's eyes narrowed in a suspicious expression. "Have you been gawking at my boob?" When she saw him shrink back, she grinned. "Geez, relax, I'm just kidding. It's my fault anyway. I can't blame a guy for acting normal, even if he is my brother."

She slipped her headsets on, settled back, and closed her eyes as a series of Eminem songs began playing. Her sweet voice sang along in a soft whisper, just barely audible

Their father kept looking back for some reason, and Mom sure looked like she was getting cozy with him. It was weird seeing them that way, which was how they were all the time lately. It seemed a little strange to him. He was looking forward to starting college in the fall for many reasons, that being one on the long list.

As the music played on and the miles of highway passed underneath, Tim rested his hand on her right inner thigh just as she'd earlier offered. He lightly tapped the fingers in rhythm with the song, carefully disguising the gentle caresses he was enjoying. The silky soft, blemish-free skin felt so wonderful. His eyes followed along her leg to the shorts where he noticed that with her leg raised over his as it was, he had an even clearer view of her panty crotch.

This time he could see nearly all of her covered pussy, including the outline of the fleshy folds. He swallowed hard as his cock twitched, beginning the cycle of arousal and frustrating denial once more. Since his sister hadn't been specific as to where he could put his hand, it inched slightly closer to her crotch.

Tim sensed her looking, so he glanced up. Without saying a word she drew an imaginary line across her thigh about two inches down from the leg of her shorts. Once he nodded his understanding her eyes closed. Fondling her shapely thigh and peeking down the leg of her shorts at the covered cunt had his cock swelling and overactive imagination in hyper-drive...

His lightly caressing fingers ever so slowly inched upward. The longer he touched her sleek inner thigh, the hotter she became. When he reached the line she'd drawn, the acceptable boundary he'd agreed to, he cautiously edged beyond, testing her reaction. When there was none, he grew emboldened. Confidence raised, the grooved pads of his fingers delicately drew across the surface of her skin. She seemed to be quivering, but he couldn't be sure.

When Tim reached the bottom edge of the leg of her shorts, he hesitated. He knew there was a line that, if crossed, changed everything in one way or another, for better or worse. His mind raced as his cock strained. There was nothing he wanted more badly at that moment but to touch her pussy, to feel the wet heat of her treasured vault, to sift through the soft curls of her bush.

Suddenly he felt pressure on his crotch. He jumped, looked up, and realized Chrissie was smiling over at him. Not a word had been uttered, but her right hand had reached over and was squeezing on his throbbing erection. They were both at that threshold, daring one another to cross it. Tim smiled back and pushed his fingers forward, caressing the skin along the elastic leg band of her flower-print panties. His cock surged even harder with her fingers helping.

Chrissie's eyes closed as her body shuddered. Being touched for the very first time down there was so very arousing. She could feel the fingertips lightly tracing the outline of her pussy lips as tingling heat flared in her loins. Her wetness immediately began flowing, leaving her cunt throbbing with excitement. Her mouth formed an "Oh" as she silently moaned, careful not to alert their parents just a few feet away.

Tim worked his middle fingers under the panties. His sister nearly jumped out of her seat as she felt someone besides herself touching her bare cunt. He tenderly pushed between the moist outer folds and into her juicy, hot slit. He eagerly explored a woman's narrow canyon for his very first time as her flowing wetness coated his fingers.

Anxious to see and feel a real man instead of a plastic sex toy, Chrissie tugged the zipper of his pants down. Her fingers reached inside and encircled his hard, pulsating shaft. Tim couldn't believe how great it felt to be touched like that. She squeezed, sending tingling heat rippling through his balls. After a few seconds Chrissie gently pulled his cock out through the aperture and gazed down at his manhood.

His sister smiled and leaned down, tongue extended and flicking, reaching for his hardness. He felt hot wetness as her mouth took his cock inside, lips descending down the rippled shaft, lower and lower, the rounded tip of his prick sliding into her tight throat. In one fluid motion Chrissie had swallowed his entire length.

Tim was amazed. His cock was throbbing harder than ever and his balls felt like they were about ready to explode! He groaned softly, hoping his parents wouldn't hear or see what they were doing just a few feet behind their watchful eyes. He moved his hands around her head and started slight pumping motions with his hips, pushing his cock as deeply into her throat.

Oh, it felt so incredibly wonderful! He didn't last long in his sister's mouth. Just as she was beginning to move her lips up and down his swollen shaft, Tim lost it. With a muffled grunting noise he ejaculated, squirting a stream of thick, hot cum down her throat. His body clenched hard as several more explosions followed, draining his aching balls of all they contained...


Chrissie roused her sleeping brother. "Wake up, dude, you're drooling!

Tim was confused. "What?"

She looked into Tim's eyes, and then slowly led his gaze to the front of his pants. "It must have been one hell of a dream. I'm hoping I wasn't the center of it!"

In the most embarrassing moment of his short life, Tim looked down at the quarter-sized white dome of milky cum that was leaking through his pants. He suddenly sensed that his crotch was filled with much more. His face turned hot and reddened in embarrassment. It quickly dawned on him that the truck was no longer moving.

Tim turned angry, and was nearly on the verge of crying. "Get the fuck away! Now!"

"Happily," Chrissie retorted as she slid off the seat and exited the truck, slamming the door closed in her wonderfully scented wake.

He was so confused and embarrassed... he wished he were dead!

The driver's door opened and he saw his father peek in. Tim immediately bent over, pretending to be gathering up the items lying on the back seat floor.

"As soon as you get that picked up, I'll need your help to get the trailer set up."

"That's fine, Dad, I'll be out in a minute."

He rushed to the bathroom. A short while later they disconnected the electrical cables and lifted the tongue off the hitch, wheeling the pop-up trailed into a good position. They took turns spinning the crank, which very slowly raised the top. Canvas-covered flaps fell out on either side, which was where the beds would be, approximately equivalent to a full-size mattress.

Once it was up and locked, Tim opened the door and stepped inside. It smelled musty after spending nearly a year at the back of the garage, but it wasn't too bad. He opened the zippers on all the screen windows to allow air to circulate.

* * * * *


Tim sat on a picnic bench gazing at the lake through a stand of trees. It was dusk and campfires were flickering all around them. There were occasional shouts and bouts of laughter as other families enjoyed time together. The sun had set but the western sky was still a dim pink, and it reflected quite beautifully off the calm surface of the water.

He was thinking very hard about everything that had happened earlier in the day. Tim was sure Chrissie had been teasing him. First by leaving the bathroom door open just enough to give him a peek at her naked body, and then by sitting the way she was... but why had she gotten so mad at him, then? That was the part that still bothered him.

Unless she'd been testing him, maybe that was it, he theorized. Otherwise, why would she then want him sitting so close, with her right leg draped over his, giving him such a clear shot at her panties? And then the thing with the drink, holding the cup against her boob and getting the shirt wet. That couldn't have been accidental. There were simply too many coincidences to ignore.

He heard the trailer door opening behind him, and then slamming shut.

"What are you doing out here getting all bit up for?" Chrissie's voice asked.

"Nothing."

She approached and sat down on his left side. They sat there in silence for quite a while, looking out at the lake as the last light faded and darkness consumed them.

"Ouch!" she shrieked while slapping on her bare leg. "I wanted to spend a little time with you, but I can't out here."
"Why are you doing this?" he finally confronted her.

"What are you talking about?" she asked, confused.

"You know, teasing me, and then getting mad, and then acting like nothing happened. It's driving me nuts!"

She rolled her eyes. "You're not making any sense. Come on inside and we can watch a DVD."

"Are Mom and Dad back yet?" he questioned.

"No," Chrissie answered as she got up. "Makes you wonder what they're doing, doesn't it?"

"I don't even want to think about it."

"Grow up; how do you think we got here?" she responded. "Well, do what you want, but I'm going back in."

He continued sitting as the trailer door slammed shut behind him.

Twigs snapped as the sounds of two people running grew closer.

"Ah!" a woman shrieked, and then began laughing.

Tim looked in the direction of the clamor and saw the silhouettes of two people approaching, both running. A woman, followed by a man, he realized. Were they his parents?

The man caught up and tackled the woman; both fell to the ground. He grabbed her ankles, separating the legs, and pulled her around his waist. They were both breathless from the sprint they'd just made. He lay on top, pinning her wrists to the ground.

"I'm going to fuck your hot cunt hard!" the man declared.

Tim immediately recognized the voice. Unsure what was about to happen, he got up and went inside.

It was dark in the trailer. An electric lantern was set on low, which was enough light to navigate by. Chrissie was sitting on their bed on the left side of the trailer with her legs crossed. She was holding a portable DVD player on her lap and was wearing her headsets. When he walked in she looked up, smiled, and pulled the headsets down around her neck.

"What's up?" she asked.

"I don't know... just bored, I guess."

"Yeah, this is lame. I mean here we are at the lake, and I'm just sitting here doing the same thing I'd be doing at home, plus getting eaten alive by bugs. It's almost not worth it."

"It'll be different tomorrow. Want to take a swim?"

She was surprised by the suggestion. "Now? It's dark out."

"That's the best time to swim," he countered. "Come on, it'll be fun. I'll even go back outside so you can change."

"What's the use?" Chrissie responded. "You already saw me naked this morning. Besides, it's pretty dark in here. Let's just change and go."

"Okay."

They located their swimsuits and placed them on the edge of the bed. As Chrissie crossed her arms and grasped the bottom of her shirt, she hesitated. "I hope you're not planning on staring at me the whole time."

"Oh, sorry."

He got busy undressing himself, but did glance over in time to see her bare, perky breasts. Despite the darkness he got a pretty good look at the naturally firm, jiggling swells and those light pink nipples he so adored. Instead of putting her bathing top on, she reached down and loosened her shorts, pushing them down her long, sleek legs before stepping out of them.

She sat on the edge of the bed naked, her thighs partially open. Tim couldn't help but look at the gorgeous sight of his hot sister. His gaze was drawn to her pussy, which he was seeing for the first time. There was a narrow, rectangular strip of dark curls flanking her outer folds, but she kept it trimmed. Even the curls that were there were closely cropped, allowing him a slight peek at the luscious pink folds.

Tim's balls tingled and his cock stirred. His shirt was already lying on the bed and he pushed his pants and underpants down at the same time, kicking them off. Chrissie was in a perfect position to see his exposed genitalia. She didn't make a big deal about it, but her eyes glanced at the partially erect shaft and hanging balls several times.

She looked up at him and commented, "You have a nice body."

Tim felt a little self-conscious standing there naked in front of his twin sister, but it also excited him immensely at some basic level. "Yeah, you too."

Once they got a peek at one another they dressed and were out the door.

"I wonder where Mom and Dad went off to."

Tim glanced over to where they were lying on the ground earlier but he couldn't see them in the darkness. He briefly wondered, then pushed the thought from his mind.

"It feels weird knowing I won't be going back to high school ever again," Chrissie commented as they walked side-by-side toward the grassy shore. "It's almost scary to think about."

He smiled. "I know what you mean. I'm a little nervous about going off to college, even though we'll be going to the same one."

"You won't forget about me, will you? It's such a big campus and we'll be in different buildings."

He reached his left arm around her waist and gently pulled her against his side. "Of course not. We'll hang out together on the weekends, do things, you know..."

"I'd like that. Can I ask you a question?"

Tim's eyes narrowed as his interest piqued. "I suppose."

"Are you still a virgin?"

He flinched. He hadn't expected such a direct question from his sister, although he wasn't sure why it surprised him given the current mood. At first he considered lying, but didn't want to spoil their close, trusting relationship. When Chrissie sensed his conflict she had her answer.

"It's okay to be one, I'm still one too."

"Really? I thought with having a steady boyfriend and all, you know..."

Her face grimaced in disgust. "Just because... Oh, never mind! Do you want to race to the end of the dock?"

He didn't really care to, but hated to disappoint her. "Sure, I guess."

She playfully shrieked and pushed off using his body. Chrissie was a fast sprinter and Tim found himself running at full speed trying to keep up. Once they reached the dock their footsteps grew louder as their bare feet slammed against the wooden planks. He was within arm's reach when she launched herself into the air, with his body following. A few seconds later two splashes sounded as they plunged into the cool lake water.

They both surfaced, sputtering and panting heavily. Both were laughing as they enjoyed the companionship. Tim began a wrestling match by dunking her. Chrissie fought back, pulling him under by his legs as she remained submerged. As they playfully fought his hands brushed over her nice boobs and once accidentally rubbed against her pussy. His cock partially hardened with excitement. He felt himself being touched by her in response.

"Okay, uncle," she finally giggled, giving up. "This was a good idea. It is better swimming at night. It's like we have the whole place to ourselves."

They looked at each other, faces illuminated by the moon overhead.

"You're really pretty," Tim suddenly blurted out.

Chrissie was caught off-guard by his sincere compliment. "Do you really think so?"

He rolled his eyes. "I said it, didn't I?"

She smiled warmly. "Thanks. I think you're handsome. Cindy does too, by the way."

Tim caught the hint. Cindy was one of his sister's closest friends and was a common fixture at the house. He'd taken notice of the cute redhead but had always been too shy to approach her. Cindy had been the inspiration for more than one fantasy as he laid in bed at night masturbating.

"How come you never made a move on her?" Chrissie asked.

Tim felt his face growing hot in embarrassment. He was glad it was dark so his sister couldn't see his reddening cheeks. He shrugged his shoulders uncertainly.

"Let's swim under the dock, that's always fun," he suggested, changing the uncomfortable subject.

"Okay."

They swam side by side into the dark shadow, where the moon's dim light couldn't reach. They stood in shoulder-deep water, their bodies just inches apart. Both were incredibly nervous as the sexual tension continued to grow. His cock hardened more and began rising into an upright position. When the head brushed against her bare thigh Chrissie knew her brother was erect.

Chrissie giggled. "I'm curious... Can I touch it?"

Tim didn't know why, but he wanted her to. After all, she'd already seen it, so what harm could it do to let her touch it?

"Okay, if you want," he agreed, acting hesitant while on the inside his whole body was shuddering with excitement.

She pressed her palm against his upper chest. It then descended, fingers trailing over his abdomen. The front of his trunks caught on her wrist, which pushed it forward, creating an opening that her fingers took advantage of. Chrissie's heart raced. What they were doing was dirty in an erotic way and wrong on so many levels, while at the same time feeling so right.

He flinched as her fingers explored, outlining his hard shaft before cupping and squeezing his balls. She giggled as his straining cock pulsated. Her fingers stroked it, making it throb.

"It feels neat," she admitted with a cute giggle.

"Can I touch a boob?" Tim asked in a weak, broken whisper as his pulse and breathing quickened.

"Just be gentle," she responded.

He pushed the cup of fabric up and over her left breast and blindly reached for the perky mound. She jumped a little as his palm cupped the soft, resilient swell. A wide smile formed on his lips as his fingers tenderly squeezed and fondled. The nipple began swelling and poked between two fingers.

"That's nice," he told her. "I've been wondering lately what it would feel like. It's even better than I thought. You are so hot-looking, Chrissie. All the guys I know at school ask me about you, but I don't tell them anything."

"Like what?" she asked out of curiosity.

"Guy stuff, like if I've ever seen you naked, what your boobs look like, what you wear to bed, things like that."

"Are they obsessed with me or something? That's creepy."

Tim turned defensive. "No, they just wonder what it's like to have such a gorgeous sister living under the same roof."

"Do you really think I am?" she inquired, needing to hear a sincere confirmation.

He looked her in the eyes. "You're beautiful, and I love you."

"You creep me out sometimes, but I love you too."

They were standing close together, bodies nearly touching. On impulse Chrissie leaned forward and briefly kissed his lips. It was so quick that it ended before he realized what had happened.

"Did you mind me doing that?" she asked uncertainly while nervously wondering what his reaction would be.

"It was so fast, I couldn't tell," he honestly answered. "Let me get ready and we can try again."

Chrissie pushed her other hand inside his trunks. As one fondled his balls, the other fingers continued squeezing around his erect shaft, occasionally rubbing over the sensitized head. She loved how erect it was, and how hard it throbbed. His body twitched and shuddered in response to the intimate fondling. When Chrissie discovered that running a finger over the tip made him flinch, she repeated the action and softly giggled.

"You kiss me this time when you're ready," she instructed, then added, "and you can do it for longer if you want."

Seeing as how she had two hands inside his trunks, it only seemed fair to Tim that he should be able to touch her other boob as well. Without asking permission he pushed the bikini off of her other breast and was soon fondling both swells.

"Can I try with my tongue?" he nervously inquired.

His sister hesitated. "I guess, but go slow. And if it feels too weird, I'll end it real quick."

Tim's shoulders shrugged as his fingers gently pinched her long, erect nipples. Chrissie's eyes closed as she moaned and quivered.

She was barely listening when her brother consented. "Okay, I'm ready, then."

Her eyes opened. A slight smile of excitement crossed her lips as he leaned forward, pressing his against hers. After their moist lips met, Tim's tongue extended, pushing into her receptive mouth. The saliva-coated tongues eagerly rubbed against each other, savoring the velvety warmth of one another. After a few seconds he was expecting her to recoil in disgust, but instead her hands grasped his cock and balls harder as her tongue turned wild, hungrily probing every crevice. He could barely keep up!

Chrissie was getting so hot! There was a fiery tingling in her pussy, making her wet and desperate. "Touch me down there!"

Her brother appeared stunned.

"Please, Tim," Chrissie impatiently pleaded.

When he made no move to please her, she grabbed his right hand and shoved it down the front of her bikini bottoms. "Touch me, please! I need you to!"

With her unexpected encouragement his fingers innocently rubbed on the rise of her love mound.

"No, lower! Please, Tim! Lower, push your fingers inside!"

Her frantic pleas made him both nervous and frustrated. He wanted to please her, but was simply at a loss through inexperience. He was also, at the same time, trying his level best to be gentle.

"Those are my pussy lips," she said as he fondled the folds. "Push harder, between them!"

Following her obscure instructions he diligently worked his fingers up and down, and was delightfully surprised when he sank into and discovered her womanly slit. It felt so gloriously warm and slick.

"Oh Tim, yes... Ohhh!" she moaned.

His sister was shaking with each stroke of his fingers.

"Do you feel that?" she asked as a finger passed over the bump of her clit.

"Yeah, I feel it," he acknowledged.

"Rub that and a girl will do anything," she giggled. "Hard, even; go on."

And so shoulder-deep in lake water in the shadow of the dock, he fingered his sister's clit with the fingers of one hand, while squeezing a boob with the other. And she fondled his balls and pumped back and forth on his stiff, pulsating erection. Their lips and flicking tongues met in periodic kisses that were hard and passionate as their young hearts soared.

When Tim's hips began making fucking motions and his body tightened, Chrissie sensed that he was close. With both hands wrapped around his pulsing cock she pulled back and forth as fast as she could, making sure that each time a palm rubbed over the bulbous tip. His breathing became helpless gasps.

"Uh!" he grunted out loud while she felt a strong burst of warmth striking her palm. "Uhh... Uhhh!"

Several powerful eruptions of hot cum hit her palm under water before rising to the surface. She kept stroking him until his tensed body went limp, followed by a final, satisfied sigh.

"That was nice. It's much better when you do it," he whispered in relief before realizing to his stunned horror that he'd just confessed to beating off in front of his sister.

Tim grimaced because Chrissie was quick-witted and fast to capitalize on such a major error. But she was so distracted with her own growing needs she barely heard his comment.

"Back up some," she hurriedly whispered.

He took several steps backward while looking at her for direction.

"Keep going, but duck down or you'll hit your head," she cautioned him.

The siblings kept ducking lower as they moved closer to shore. Tim was a little confused as to what she wanted. A few moments later they were crawling forward as the dock converged with the land, leaving just a tiny crawl space. Chrissie lay down in the shallow water on her left side facing him.

The fingers of both sides simultaneously tugged at the knots holding her bikini bottoms in place. Once undone, she slipped it off and bent her right leg at the knee, exposing her eager pussy for his continued fondling.

Sensing her brother's hesitance, she smiled encouragingly and waited for him to make the first move. After a few moments his right hand reached between her legs, a middle finger easing between the outer folds. He was again greeted by the slick heat of his sister's aroused center. Her body jumped when he again found the tiny bump and resumed rubbing on it.

After a few moments Tim took charge of the intimate interlude. He gently pushed Chrissie onto her back just like he'd done so many times while fantasizing. And incredibly enough, as if she had also seen the mental visions, her sleek legs eagerly widened. His mouth found hers as his middle finger returned to her womanly slit, caressing the wondrous nub hard just as she'd earlier invited.

Chrissie loved the way her twin had finally taken control, just like in her fantasies. It almost seemed as if he'd somehow glimpsed into her mind and seen what she truly wanted. Her legs anxiously separated, revealing the most secretive part of her body while welcoming his sexual intrusions. All of the fighting their parents complained about was the ugly side of growing sexual frustration, but now the siblings had finally discovered one another's secret longing.

He kissed her hard, tongues entwining before he began searching her mouth. She was already quivering with building arousal, heightened more as she felt his free hand reaching around and pulling the tie of her bikini top apart. The way he was commanding the moment energized her body. Her heart was pounding, adrenaline racing through her flesh. She wished he hadn't cum yet, because her aching pussy yearned for the hardness of his cock.

Tim pushed the fabric upward, which was still attached around her neck, exposing the perky mounds. He drew a swollen nipple between his lips, tenderly licking and sucking on the vibrating tip.

"It looked to me like they were going swimming," their dad's voice softly spoke.

The twins froze and looked over, seeing two people standing on the shore near the dock, visible only from the knees down.

"I'm worried, Ben. It's getting late, and this isn't like them," Mom announced in a concerned tone. "I hope... Oh no, dear God no, not that..."

The legs changed positions as their father took their mother into his arms and softly chuckled. "Please, sweetheart, don't let your imagination get the best of you. They probably lost track of time is all. They're both adults and are quite capable of taking care of themselves. I know Tim would never let anything happen to Chrissie."

"But they fight, baby. What if..."

After a brief pause their father suggested, "Come on, while the mice are away maybe the cats can play. Are you game?"

She sniffled a few times. "I'm sure you're right, but if they're not home in the next hour..."

"...I'll drive to the ranger station myself," he finished. "Come on, we have a perfect chance to do some very naughty things."

"But... Are you ready this soon?" she questioned.

"Let's find out," he responded as their feet disappeared from view.

They remained still and silent for the next few moments. Chrissie had expected the unintended interruption would have spoiled the moment, but once Tim was sure they were gone he resumed the intimate touching and sucking. It was almost as if it had never happened... or better yet, the close call had actually pushed her closer to orgasm.

A minute later they both heard the soft, distant metallic slamming of the trailer door closing. Seconds later Chrissie's stimulated body clenched in climax. The breath caught in her throat as she suddenly stiffened, softly moaning in pleasure as her virgin sex tightened reflexively, as if a cock was buried deeply inside her. It grasped at nothing in vain as hot juice trickled from her satisfied center.

She relaxed, enjoying the feeling of the water lapping at her body, cooling it. Her brother pulled away and lay down beside her.

"Was that okay?" he innocently questioned, hoping he'd returned the favor as well as she'd pleasured him.

She returned to his side. "Do you want to know the truth?"

His stomach dropped. "Was it that bad?"

Chrissie giggled. "No, silly, what you did was very nice. But guess what I was thinking?"

Tim was confused. "Maybe that you should have done this with your boyfriend?"

"No, that I wished your cock was still hard."

It took him a few moments for realization to set in, after which he grinned. "You mean..."

"That's exactly what I mean!"
