It was just past two o'clock, on a hot summer afternoon, as Mark pulled himself up out of the water and onto the deck of the swimming pool. The pool water had felt refreshing after the job of mowing the lawn was over and Mark figured it was a good time to get a little bit of sun. The boy stood up on the deck and allowed the water to drip on off of him, then grabbed a towel and dried himself off as best he could. His shorts were still wet, and they clung to him tightly.
That didn't bother him; actually it felt kind of good. He lay the seat back of the lounge chair about midway before sinking into it; his feet up, the sun feeling nice and warm on his chest.
As Mark soaked in the suns warm rays and relaxed, his thoughts drifted back to those of the previous night; with his girlfriend Karen. Mark and Karen had been 'dating' since the spring; just before the end of school, and Mark had looked forward to the summer, hoping that there relationship would move into 'new' areas. She was a very pretty young girl; slender and petite but athletic, a long blonde beauty with a body to match.
Unfortunately, Karen was being raised in a rather conservative home and was reluctant to follow nature's adolescent callings so easily. The two had found themselves alone at Karen's house, and while making out on her couch, had gone further than ever before.
She had not only let him slide his hand up her blouse, but she had not been wearing a bra; he had felt her bare, firm tits for the first time. It made him so hard, he felt like his dick was about to break. But Karen would go no further than that, insisting that her parents would be home at any second, and ended the evening. Mark left for home, frustrated and sore. He had been close enough to his dreams, and he craved inside for Karen to open up and let him have his way with her.
However, Mark was sure it was simply because she was scared, so far she had not even touched his cock; not even through his pants. After returning home, and in bed that night, Mark had reached down to to relieve his adolescent stress.
He stroked himself, slowly at first, building to a climax, finally spewing his cum all over his stomach and hand. Still not satisfied, he had kept playing with himself, rubbing his cum over his cock before getting hard again and furiously jerking off one more time. At least it calmed him down enough so he could get to sleep. Surely the time would come soon when Karen would give him everything he wanted.
He desperately wanted her; just to stroke his cock, maybe even put her mouth on it, to feel what it would be like to put it inside of her, to fuck her. But for now, all he had was his own hand. Mark was a good-looking boy, newly turned 16, his hair dark brown, big brown eyes and a tan that got the attention of a lot of girls. At only 5'6", he was slender, yet with just a touch of muscle beginning to break through, making him look very attractive anytime his shirt was off.
Some girls said his facial features were "cute," while others described him as downright "handsome." Since he had been going with Karen, he had wondered several times over the past three months if he hadn't cost himself the chance to lose his virginity with another girl. So far, he had been faithful to her, but he didn't know how much longer he would last, unless she started giving him the sex he craved. As he lay there in the sun, thinking about the night before, he began to get an erection.
"God, her tits felt so good, and so firm!" His mind recapturing the moment. The more he thought, the more his cock reacted and, unconsciously, the handsome teenager reached down and began to stroke his cock through his slowly drying shorts.
"Mmmmmm." he softly moaned. He gazed over at the sliding glass door and windows of the house, and then around the large privacy fence which encircled the pool area and pondered; his Mother and Father were off at work, they wouldn't be back for hours; his little step-sister, Sara, was god-knows-where and most likely wouldn't return until shortly before their parents did. He was all alone and could do as he pleased. Mark considered getting up and going to his bedroom, but he was so comfortable sitting in the sun, in the lounge chair, feeling the warmth on his skin, and with the thought of doing it out in the open exciting him even more, and he stayed right where he was.
He let his hands slide to the waistband of his shorts, and hooking it with his fingers and lifting up his hips, he slid the suit down to his knees; letting his now-hard cock spring free. He lay there silently, looking at his penis, standing up off of his hips, and enjoyed the sensation of the wind as it blew a cool breeze on it. His dick was of average size, six inches long or so; but longer than other guys his age (at least he thoughthaving never seen anyone else with an erection), and it made him feel mature; looking at his erection.
As he lay there looking at it, he began to fantasize sliding it in and out of Karen's lips or of her straddling him right there and then, and of penetrating into her. His thoughts of her made him even hotter and, looking around once again, Mark reached down to slide the bathing suit all the way off, laying it beside him on the deck.
It was a new sensation for him; being nude, outside, and it was a real turn on for the youngster. Feeling he had plenty of time, he curiously allowed one hand to slide to his nipple and caress it. Mark began to realize why Karen liked that so much, feeling the sensation when he did it to himself.
As he caressed the nipples on his hard chest, his other hand slid down to gently cradle his balls with his fingertips. Mark moaned softly at the feeling, catching himself and worrying that he might have groaned too loudly. He caressed himself in self-foreplay, letting the feelings build and build within him; getting hotter and hotter, touching himself, thinking of Karen, wanting to fuck her, wanting to fuck her mouth and wanting to cum in her.
Gently, he moved his hand to grasp his rock hard cock and began stroking it, slowly at first, then a little faster. It felt too good and although he knew that he didn't want to cum just yet, he wouldn't be able to hold it back much longer. With one hand playing with his balls, his other began moving faster and faster, up and down his hard cock; pumping it, making it feel so good, he was quickly reaching an orgasm. His scrotum began to tighten and pull tight to his groin, becoming incredibly tense and sensitive, and his cock began to swell and stiffen to its limits.
He could feel an almost boiling sensation in his balls and he groaned aloud as he began to reach his orgasm. His fist was nearly a blur on his cock as he jerked himself off, urging the it on; faster and faster. His spurting young cock blasted it's release high onto his chest; then again, lower onto his belly. He continued to pump from deep inside until the final spurts dribbled down his hand and slowly over his pulsing erection.
Mark finally relaxed his body, still holding his cock, slowly caressing and milking it in his hand. "Wow." He heard. The faint, almost breathless sound come from the shade under the patio awning. Without having to look, he immediately recognized the sound as that of his little step-sisters voice. Without a thought, his head turned quickly to the sound, the rest of his body frozen, to see her standing in the opened sliding glass door; in her swim suit, a towel in her hand.
He lay there unable to move; nude, his cock in his hand, his belly and chest covered with his cum. "Uh.Sara.uh.ummm." he stammered; still not moving, still holding his cock and looking with worry at his little sister. Although Mark had nearly always considered Sara his sister, she was in reality his step-sister. His mother had re-married his step-father when the two kids were both young, nearly 10 years ago.
It was early enough that both considered their respective step-parent as "Mom or Dad" even though they both knew the truth. The two grown to be comfortable as siblings, close you could even say, until the last couple of years or so. For the most, part Mark had begun to ignore his little step-sister, not out of malicebut more that as he'd headed into puberty, he simply relegated her to being " a little kid". For a moment, he just lay there, speechless, hoping she would turn and run, not knowing or understanding what he'd been doing.
But she didn't. She just stood there, staring at him. Then he noticed that her eyes, wide when he first saw her, now seemed filled with curiosity and awe.
She was looking at her 16-year-old brother's nude body and apparently, enjoying what she saw. Without saying a word, she began to walk over to him slowly. "Sara!?!" He called out at her, surprised at her reactions.
"It's ok, Mark. I know guys do that. We read about it in sex-ed class. You know, "wet dreams" and all that stuff." She said to him as she stepped closer. Mark was stumped, completely at a loss for words.
But it was more than what she'd said, it was the look in her eyes as she'd said it. It was almost "matter-of-fact", or as if she wasn't really talking to Mark but to herself, and he noticed that her gaze was clearly fixed on his crotch as she neared.
It was as Sara stepped out from the shade and into the sunlight that Mark noticed a difference in Sara. He has recognized for some time now that she'd began maturing; she had began to wear a bra, becoming very concerned with her appearance, normal adolescent changes.
But until that moment, he had been unaware of how just much she had changed.
Although Sara was wearing a one piece bathing suit, Mark could see that her breasts had matured; proportioned to her small frame, but firm and full. She had always been what you would consider cute; Long, wavy brown hair past her shoulders, and big, soft looking eyes.
Sara had always been thin, but now he could see there was a curve to her hips. With her petite size and thin physique, she had developed a very attractive figure.
"Oh.my.god." Mark thought to himself, seeing her for the first time in a sexual way and realizing that Sara had grown to become one hot looking girl. Sara continued walking over to Mark's lounge chair, and much to his suprise, gently knelt down to her knees beside him.
She was looking at his crotch, his erection quickly shrinking; encased in his hand. "Sara !?!." He said in a raised voice of embarrassment, "Do you mind !?!" "Oh, relax Mark. It's not like I've never seen one before." she said to him, again in a 'matter of fact' way.
"What !?!" Mark replied in shock. "Sure! Sally's little brother runs around the house naked all the time." She stated proudly. Sally was Sara's best friend, and Sally's little brother couldn't have been more than three years old.
"This is a little different!" Mark snapped, with a growing tone of annoyance. "Well.", she started, ".I know, Mark. But. I was just wondering.
HOW different?" Mark was floored by her boldness, the way she was intently looking at the hand covering his crotch, so much so that he just laid there speechless, his jaw dropping open. "Come on, Mark. I remember when we used to share everything." She pleaded to him in an innocent way.
Instantly, Mark's mind raced back, way back, to an afternoon play session in their basement. The two of them were 7 and 9, and Mark had talked Sara into playing "doctor"; with Mark as 'The Doctor'. He remembered how excited he had been 'playing the game' and then how terrified he'd been that she would say something to their parents, or anyone else for that matter.
But without ever saying anything to her, she never did. "Can I see it?" she asked, still staring at the hand covering himself.
Mark could hear a twinge of both excitement and curiosity in her voice. "Sara !" he replied, almost incredulous, "Your my sister!" "I know, I know.", she said in an apologetic tone, ".but it's not like were REAL brother and sister." Her words cut into Mark, an he was surprised to hear her say them. He was even more surprised at how much they hurt. For whatever reasons she might have bothered him over the years, he still felt of her as a little sister, protective of her.
He liked the way that she looked up to him, and how it made him feel more mature. She turned to look at his face, and with soft and innocent eyes squeaked out, "I swear, I won't say a word." Mark just looked at her, unsure. "Please?." she whispered.
It was too much for him to say no, his guilt level rising. Her curiosity seemed genuine enough, and besides, she was so cute looking that he couldn't resist her plea. "Not a word to anybody! Promise?" he asked her. "Yes.," the young girl replied with an excited glee.
".I promise!" Hesitantly, Mark moved his hand from his crotch, exposing his now limp and shrunken penis. Sara looked at it intently, studying it. The way that she was looking at him, her intensity of thought as she examined his cock with her eyes, was beginning to turn him on; something he never in his wildest dreams thought would happen.
He let his hands move further away, moving both of them slowly up to his chest and attempting to cover the spots of cum that were still pooled on him.
Aware that he was fully baring his body to his little sister, and seeing her excitement, he began to quickly gain another erection. "WWWowww !" She stared in amazement, watching his penis stiffen; more and more, growing as it engorged with blood.
It almost took her breath away, and her eyes opening wide at the site. "Is this the sperm?" Sara asked, pointing to a small splotch of cum on his stomach. "Ummm. er. Yeah," Mark hesitantly replied, feeling a little embarrassed. "Well, it's more than just that, sometimes people call it cum." Sara grinned nervously. She reached out gingerly and touched the puddle of cum with her fingertip.
She lightly daubed it with her finger and then slowly began swirling it, feeling its slickness. The sensation of her touching his stomach as she played with his cum excited Mark even further, and his cock began to strain with stiffness. "It feels weird!" Sara giggled, still playing with it. "It's so slippery." "Um. yeah. It's supposed to be." Mark replied. "When does it come out?" She asked him, still mesmerized by his fluid. "Well. when you have an orgasm." He said. "You mean when you.
like just now?" She said, stunning Mark again with her boldness. "I heard you groaning. in your bed last night. Were you.?" "Umm. yeah." He answered, feeling even more embarrassed that he'd been caught again. "So. what does it feel like?" She asked. "Well.", he hesitated, searching for an answer, "It feels really good." "Can I watch you.
you know. do it?" she asked, her eyes moving back to his hard on. She could sense his hesitation to her question, and added, "Please?" Mark thought for a second, his mind racing with excitement of the idea; jerking off while his step-sister watched him.
It was almost more than he could withstand; she WANTED this, wanted HIM. His cock was rigid with anticipation, and after a moment of hesitation, he slid his hand down his belly and gently grabbed hold of his cock. Slowly he began to stroke, all the while watching Sara's excitement growing.
He could see the profile of her face, her eyes bulging with excitement as she watched him begin his ministrations, and his excitement grew with alarming speed. She watched him slide his hand up, then down over his already slickened cock, slowly at first, but soon faster and faster. Sara began to lean down, wanting to be closer, to see more, when her hair slipped down off of her shoulder and swept down across his belly.
The feeling was electric as her hair tickled his skin, and his excitement caused him to unconsciously twitch, and quicken the pace of his stroking more. He closed his eyes, trying to regain his composure, but it was futile. It was then that he felt her hand touch his elbow, and slowly it began to slide up his arm toward his thumping hand. The excitement was too much for him, and he was rapidly nearing a climax.
"Sara." He moaned out, his voice straining as he quickened his jerking. "I'm gonna.," the words barely out of his mouth, as he began to explode, ".cummmm." His cock erupted what felt like a geyser of cum, more than he had ever done before. Again, and then again he sprayed out his cum, and it felt as though it was draining him completely; the sensation was incredible.
Sara's hand had made it's way up to his, resting upon it as he continued to milk himself empty. She slid her other hand down across his belly; catching, then smearing his cum along his taught belly and down below his navel.
"Wow!" She cried out, in total excitement. "It's so warm!" She squealed with delight. She continued to rub it into his belly long after he was done, his hand having stopped and let go of it's grip. He closed his eyes and relaxed, basking in the sensation of her fingers rubbing his cum on his skin.
"That was amazing!" She said softly. "I wish I could do that." No sooner than she'd said her words, with Mark resting his head down on the lounge in relief, than the telephone rang. Both of them were startled by it's sound, with Sara jumping up to her feet and grabbing her towel.
She quickly scrubbed his stickiness off onto her towel as the phone rang again. "Oh Shit!" She cursed under her breath with nervous excitement. She turned to dash for the patio door, but stopped for a second and looked back at her brother Mark, and a huge smile grew on her face.
The phone rang it's third chime, and Sara nervously laughed out, "I think that's Sally calling me?" It was apparent to Mark, looking at her standing there fidgeting and nervously clenching her fingers, that what she was looking for was answer as to whether or not she should answer the phone. He answered her nervousness with a nod and reached down to grab his shorts. As Sara dashed to answer the phone, Mark jumped back into the pool to clean himself off, and slipped back into his trunks under the water.
Mark bobbed in the water anxiously for a moment, nervously thinking about what he'd just done, and decided that he wouldn't wait for Sara to return.
As soon as he was cleaned and clothed, he got out of the pool and dried himself quickly, heading up to his room to get changed. His mind was racing with what had happened, and realizing that he was pacing in his room Mark decided that he'd better get out of the house for a while.
It was almost 10 o'clock before Mark returned home, his parents wondering where he'd been. He made up an excuse that he'd been over at a friends house and had forgotten the time. Truth was, he'd been out riding his bike, going nowhere in particular, aimlessly thinking about what had happened. After listening to his mother chirp at him for not calling, and then her making up for it by asking him if he was hungry (which he was definitely not), he told them that he was going to bed.
He passed by the living room on his way, and glancing in, saw his sister curled up on the couch, watching TV. She looked up at him with a concerned twist to her, but he didn't stop walking. Climbing out of his clothes and jumping into his bed, Mark fell almost immediately asleep, exhausted and drained.
It was almost noon the next morning before Mark finally woke up, having slept hard and sound all night. He sat up in his bed and flicked on the clock radio on the night stand. He started to think about the day, and immediately flashed back to the day before. He had been sitting for only a few minutes when he heard a light knock on his door. "Who is it?" He asked. "It's me." Called back Sara through the door, "Can I come in?" "Just a minute." He called back, hopping out of bed and quickly throwing on some shorts from his drawer.
He walked over and opened the door, Sara standing there looking upset. She followed him into his room, shutting the door behind them as she entered. Mark walked back over to his dresser before turning around to see her still standing by the closed door. "Mark.?" She started, "Are you." She broke her gaze him him and looked down at the floor and continued, "Are you. mad at me?" "MAD at you?" He replied in disbelief, 'Mad for you' he thought to himself.
"Yeah, you know, about yesterday. um. at the pool?" She said. "What I mean is. umm. well, when I came back after I answered the phone you weren't there.
And then I realized that you weren't even in the house, and I." Her voice trailing off. "No, god no. I'm not mad at you. It was just that." He started to apologize to her, not really knowing for what. Taking advantage of her in some way he supposed; his guilt feeling heavy at the moment. "It's just that.", he started again before Sara interrupted him.
"I wanted to do that." She stated, still looking down, but raising her eyes to him looking for approval, "Really." He was touched by her sincerity and didn't know what to say. "I liked it." She added, ".alot." "I see." He said, attempting to sound calm, reluctant to admit how much he too had enjoyed the experience.
"I'd like to.", Sara stammered out, "I mean. well. if you ever want to. umm." He never really answered her, just gave an approving smile, but that was enough to answer her question. She smiled back at him, then turned and opened the door. "I'll. umm. see you later." She said, and closed the door behind her. Mark was beside himself, he couldn't believe this was happening to him.
It was so wrong but it was also so irresistible. He felt incredibly guilty, still, as if he'd precipitated this whole thing, no matter what she said. But on the other hand, she wanted to do it, she really enjoyed it; 'ALOT' were her words. "But what did she mean by 'if I ever want to.?'" he thought to himself. It was almost too much to take in at one time, so again he decided that he'd better get out of the house.
Mark spent the better part of the afternoon just meandering around, thinking intently about what had happened and feeling incredibly horny. By late afternoon it was becoming more than he could take, and he decided to pay a suprise visit to his girlfriend Karen's house. Much to his delight she was home, although not alone. She was baby sitting her little brother for the day and was surprised to see Mark at the door. Karen reluctantly let him in, making sure to tell him that her parents had specifically instructed that she was to have no visitors while watching her brother.
After sitting together for a while, noticing that Karen's little brother was essentially asleep on the floor in front of the TV, Mark leaned over to Karen and began to kiss her neck. He felt a bit of resistance from her but she always seemed reluctant at first. He continued to nibble at her neck and began to massage her leg with his hand. For a moment, Karen seemed to relax a bit, fueling Mark's excitement and ambitions.
Slowly, he slid his hand up under Karen's shirt in hopes of repeating his earlier petting session with her, but his move was immediately thwarted by Karen's grabbing of his hand and issuance of a definite, "NO!". As hormonally geared up he felt at that moment, she might as well have slapped him across the face. His mind raged in frustration, and he was afraid to open his mouth for what may come out. Mark stood up abruptly, announcing, "I gotta go!", and left just as quickly.
He thought about the incident the entire bike ride home, beating himself up for possibly blowing any chance of Karen loosening up to him. His tension, both sexual and emotional, was beginning to take its toll.
"Fuck her, fuck her anyway." He thought to himself. "I don't need her." It was at that moment that he began to question his memory of what his sister had said to him. "I'd like to.", He remembered. "I liked it." She had said, ".alot." Again he wondered, "What did she mean by 'if I ever want to.?'" Mark arrived home to find his mother heading out the door. She was walking to her car, still dressed in her work outfit and moving in a brisk pace. "Mark, there you are." His mother said as she threw her purse into the car and across the seat.
"What's up, Mom?" Mark asked. "I'm was supposed to have met your father over twenty minutes ago for dinner, so I'm running late." She said, busily starting the car. "Oh." "Now listen, I left some money on the kitchen table for you and Sara to order some food. Sara's over at Sally's house but I've already told her to be home by seven." She rattled off. "Where are you two going?" Mark asked. "Well I'm not sure yet, we're going out with John's boss and then we're supposed to go to a party, so.?" She had the frantic look of not really wanting to do this but feeling obligated.
"All right, Mom. Have a good time." Mark gave her a slight wave as she spend out the driveway. Mark made his way into the house, stopping by the kitchen to find the money on the table. He went ahead, grabbing the phone, and ordered a pizza pie for delivery and plopped himself down onto the family room couch to watch some television.
It was about a half hour later when Mark heard the doorbell ring, the food had arrived but Sara wasn't home yet. After paying for the pie, he took it into the kitchen and set it down on the counter, glancing over at the kitchen clock to see the time. "7:30. good thing for Sara that Dad isn't here.
I'd have gotten holy hell for being late when I was her age." Mark thought to himself. Not bothering to fix himself a plate, Mark stood at the counter eating the pizza from the box. He was finishing up a second slice when he heard Sara come in the front door. She passed by the kitchen door and noticed Mark standing at the counter, tossing him a look of puzzlement as to why he would be eating that way.
"Dinner?" She asked him. "Mmm." He nodded in reply, chewing on another slice of the pie. "God, you eat like an animal sometimes." Sara remarked, loosing whatever appetite she'd had watching Mark inhale his food. Her remark garnered a few token grunts from Mark, and an exaggerated facial expression as well. It was enough to drive Sara away, heading down the hallway to her room, much to Mark's amusement.
Mark packed up the rest of the pizza, tossing the box into the refrigerator, and sat back down on the family room sofa, content with a full belly. He surfed around a while, not finding anything interesting to watch when Sara walked in and sat down in the lounge chair. What'cha watching?" She asked.
"Nothing." Mark replied. He flipped through the channels again to no avail, settling on one of the music video channels for a while. The two sat and watched for a while, neither saying much to the other, until Sara stood up out of her chair. "How late Mom and Dad gonna be?" She asked.
"Mom said probably late, they're going to some party at Dad's boss's house or something." Mark answered her. "Oh." Was all she said, walking out of the room and down the hall. Mark turned his attention back to the tube but quickly tired of finding nothing to watch. He headed for his room, hoping to find something of interest to do, and as he passed by the bathroom across the hall from his door he could hear the sounds of Sara lightly singing to herself in the shower.
He plopped himself down onto his bed and flicked the lamp on his night stand, kicking off his shoes and socks and picked up a magazine that lay on the stand.
He lay there in his bed, staring at the magazine but scarcely read a word; distracted by the sounds of his kid sister across the hall. He could hear her in the shower and couldn't help himself but to begin visualizing what she might look like. "She looked pretty incredible in that bathing suit." He thought to himself, remembering the supple curve of her hips, the smoothness of her skin and the enticingly ample size of her breasts; and he found himself getting an erection. Mark stepped up off of his bed and walked to close the door to his room when the bathroom door across the hall swung open.
Sara stepped out into the hallway, wearing only a towel wrapped around her midsection, and drying her hair with another. Mark felt a bit awkward, unconsciously envisioning what he'd been daydreaming about just a moment ago, as he stared at her. Sara jumped with a startle when she realized that Mark was looking at her. "Jesus, Mark! You scared me!" Sara giggled out.
"Ummm. sorry." Mark replied, slowly closing his door. He retreated back to his bed, feeling incredibly horny but a bit reluctant to do anything about it just yet. As he lay on his bed, thinking of Sara, fighting the urge to slip off his shorts and grapple himself, there was a knock at the door. "Mark.?" He heard Sara softly call out.
"Yeah. I mean come in." He replied. Sara opened the door slowly, stepping in cautiously. She had her hair wrapped in a towel, turban style, and had put on a nightshirt; long and loose but made of a soft thin cotton that acted almost as a second skin. She nervously stepped into Marks room, looking around as if to see if anyone else was there.
"What 'cha doin?" She asked. "Nothing, really. Just sitting here." He replied, uncomfortable with the idea of telling the truth to her. "What's up?" "Oh.
nothing much. I just wanted to say hello. you know." She answered. There was a long pause of silence between them, Sara just milling about Mark's room, looking at his effects curiously.
He watched her as she wandered about, soaking in the view of her nervously as she turned her back to him, looking at the curios on his desk. "Mark. can I ask you a question?" She asked, still turned away from him. "Ummm. sure." He replied, embarrassed by the nervous tone of his own voice. Sara turned around to look at him, standing with her hands nervously pinching at the sides of her nightshirt. " Mark. I was just wondering.
I mean." Mark could easily see the anxiety in her face, her skin slightly flushed. "What I mean is. ummm. do you think. uhh." Sara paused again. "Yes?" Mark asked, trying to relieve her tension. "Well, how often do you think about sex?" She finally blurted out. "How often do I think about sex?" Mark laughed out in response. "Mark!" Sara snapped, obviously hurt by his reaction to her question.
"I'm. I'm sorry, Sara. I didn't mean it like that." He apologized. "I'm serious," She said, ".really." "Jeez, I don't know. I never really thought about it. Why?" Mark responded, unable to admit to Sara that he thought about it almost 24 hours a day. "Well. because.," Sara paused for a moment trying to muster up a little courage, " .cause ever since the day when.
well you know. I've been thinking about it alot." "Alot?" Mark asked; his curiosity piqued. "Yeah." Her nervousness seemed to fade as she saw his interest. "Like. constantly. I mean, it's all I seem to think about." "Really?" He replied, in a more suggestive tone.
"Well. yeah." Sara admitted, loosening her grip on her shirt and relaxing her stance a little. "Well." Mark started, pausing for a moment to think, ".what do you think about?" "Ummm.
well." Sara started, finding herself pausing when her began to blush. "Go ahead, you can tell me." Mark encouraged her. "Well. I've been thinking about what you were doing the other day and." She paused again, looking to Mark for reassurance. He said nothing, just gave her a nod of approval and she continued. " And, well, how it made me feel." "Oh." Was all that Mark replied, unsure of what Sara meant by it. Sara stood silently, unsure herself of what to say.
"How did it make you feel?" Mark asked with nervous curiosity. "Well. weird." She saw the look on his face turn to one of trepidation, and she quickly continued on, "I mean, not like a bad weird, but more like a good weird. kind of tingly all over, you know?" Mark began to relax a bit, seeing that she was looking for approval, or validation of her feelings.
"Did you like feeling. tingly all over?" Mark asked, again curious. " Sort of." She replied, looking at him with nervous eyes, "I guess?" "Oh." Mark said, again unsure of what to say. He was still lying on his bed, unmoving with tension, looking at Sara as she stood silently near the foot of his bed; equally as nervous.
Mark felt uneasy looking at her, but found it difficult not to stare; wanting desperately to undress her with his eyes. Sara stood motionless, looking only at the foot of his bed, when she took in a deep breath. "Mark?" She asked, holding her breath at the same time. Mark lay silently, looking at her face, waiting anxiously to hear her question.
"Do you want to." She paused as she looked up into his gaze, ".you know." Mark didn't know. At least, he couldn't be positive what it was that she wanted but he definitely knew that he was feeling a rapidly growing sexual tension inside.
His mind was racing with questions, as well as his urges, but he lay frozen in a moment of indecision. "I mean. if you feel like it.?" Sara continued nervously. Her eyes moved from his and slowly meandered down to his waist, and she nervously bit her bottom lip; concerned that she was asking too much, to directly. The anticipation in her voice was enough to convince Mark that Sara indeed wanted a repeat performance of his little poolside show, and it was enough to consolidate his courage.
Slowly, and without saying a word, Mark sat up in his bed and lifted off his t-shirt, then gently laid himself back down, resting his head on his pillow. Sara stood still and silent, her eyes growing wide and her lips began to smile, reassuring Mark that he was exciting her.
She watched Mark reach to his waist and begin to unbutton his shorts, gently arching his back to slip off his pants and kicked them onto the floor. He paused for a moment, noticing the stare of delight in her eyes as they were fixed on his body. She took a small step toward the corner of his bed, all the while never moving her eyes from him.
As she took another small step closer to the bed, she began to notice the growing bulge of his underwear. Mark gently began to stroke his stiffening penis beneath the soft cotton of his short, enjoying the sensation and becoming more excited by the look of desire on Sara's face. "Does that feel good?" She asked, still staring intently. "Yes." He replied. She took another step, coming to the corner of his bed and sat down slowly on it's edge.
The closer she came to him, the harder he became, soon the tip of his cock becoming exposed as it strained it's way underneath the elastic of his underwear. Sara attempted to swallow away the dryness in her mouth, as she inched closer to Mark.
He continued running his fingers along the underside of his shaft, gently stroking the head of his cock with his fingertips as he went. He was waiting for Sara to move closer to him, but she hesitated, content to sit and watch him play with himself. His tension was growing to the point where he could not wait any longer, and he hooked his thumbs under the elastic pulling his underwear down enough to release his straining erection, pulling the elastic down to rest underneath his balls.
His cock stood rigid, hovering above his waist. Again Sara attempted to clear the dryness of her mouth to no avail, her eyes transfixed on Mark's cock. He gently wrapped his fingers around his shaft and began to pull the skin up, then down. Slowly at first, then faster and faster he pumped. He closed his eyes and lay back his head on his pillow, focusing his attention on the feeling of his cock in his hand.
Faster and faster he pumped. Slowly, his mind began to loose it's concentration as visions of Karen began to creep into his thoughts. The more he thought of her, the further away the sensations of his penis became; and so the faster he pumped. He desperately wanted to come but couldn't keep the distracting thoughts of Karen from his mind.
His body began to become rigid with anticipation of release; faster and faster he pumped. Finally he began to feel the familiar feeling deep inside, and he knew that he was getting close. He gently opened his eyes as he continued to pound away frantically, having almost forgotten that his step sister was watching him intently. As he saw her face staring intently into his, he unconsciously moaned out, "S.
Sara." With a suddenness that shocked him, Sara jumped up off of the bed, almost falling as she did. The speed and strength of her movement alarmed him, immediately causing him to stop his movements, and lift his head up off the pillow.
"Sara?" He called out to her, his voice pitched high in alarm. He lay stiff and still, his hand still firmly grasping his cock, as he stared at Sara. She was standing by the bedside, her face nearly white as a sheet, her body visibly trembling. "I. I." She began to speak but halted as her knees nearly buckled, causing her to twitch to keep her balance. Her mouth opened as if to speak but nothing came out, and then with an equal sense of alarm, she shot toward the door.
Mark stared in panic and confusion as she raced out of his room and into her own. "HOLY SHIT!" He thought to himself, "Holy Shit!" He sat up in his bed in an effort to find out what had happened, his mind reeling in confusion, when the elastic of his underwear had no more to give and pulled tight against his balls.
"Fuck!" He screamed out, the intense pain of his testicles being squeezed shooting through his groin, sending him crashing back down hard onto his bed. "Fuck!" "Jesus. what happened?" His mind raged as he pulled his underwear back up, feeling the relief of his sensitized balls. "What the fuck happened?" Whatever it was, he reasoned that he'd better find out; and quick.
He gingerly stood up out of his bed, gently grasping his balls through his underwear, rubbing them softly to ease their pain.
"Oh. shit. I think I said her name. I called out Sara's name." He realized. His legs finally feeling normal under him, he stepped out into the hallway and over to Sara's bedroom door. He stood silent for a moment, having absolutely no idea what he was going to say, and wondered what she was thinking, wondered what he'd been thinking by getting into this mess in the first place.
As he stood at the door, cursing himself and gathering his courage once again, he heard a noise from inside of her room.
He couldn't tell what it was, but thought it to be the muffled sounds of Sara crying. "Sara?" He called out through the door. Nothing. "Sara, please." He said again with a little knock on the door.
He heard no response from Sara, only more noises from her room. Finally deciding that whatever was going to happen had to be now, Mark slowly opened Sara's door and stepped into her darkened room. "Sara, I." Mark began to call out but stopped as his eyes began to adjust to the darkness, and from the dim light spilling in from her window, Mark saw Sara lying on her bed.
Slowly closing the door behind him, he stepped into the room quietly, slightly perplexed by what he saw. The comforter and sheets were gathered at the foot of her bed and Mark could see Sara lying on her back, her knees splayed outward with her arm reaching down between them. Her head was pressed down into her pillow, deeply enough that he couldn't see her face. He stepped closer to her bed, entranced by the sight of her, as he could now see her hand frantically rubbing her pussy over her thin cotton panties.
Nearer still, he could see her eyes tightly closed and her mouth agape as she panted and moaned. Something inside was guiding him, as he couldn't help himself from walking right up to the side of her bed, mesmerized by the sight of his kid sister furiously masturbating, totally absorbed in her own ecstasy.
In an instant, he was hard once more; his cock raging with excitement at the sight before him. As he stood at her side, watching intently as she massaged herself; her face beading with sweat, her skin glistening in the soft low light. His hand crept to his cock, rubbing it though his underwear as his eyes danced over Sara's writhing body; her nightshirt pulled up just below her breasts, exposing her smooth and flat waist, her hand grinding her pussy into her pubic bone madly, the other gripping tightly to the taught sheet of her bed.
He could hear the sounds of her breathing; shallow and quick, along with the soft moan of her voice. Faster and faster her hand moved, pressing harder onto herself as she rubbed, and it was more than Mark could take; feeling that he was going to explode in his shorts.
He reached for the waistband of his pre-cum soaked underwear, lifting it up and over his straining cock, releasing it stand erect over her, when suddenly Sara drew in in a deep breath; her body tensing.
Her head lifted up off of the pillow with her mouth open, but holding tight to the air that filled her; her eyes bulging wide as she looked directly at Mark with a glazed stare. Her hand became a blur as it mashed at her cunt, and a slow moaning gasp escaped from her lips; she was coming. Mark stood frozen watching Sara as her body convulsed in one wave of ecstasy after another.
She continued to rub feverishly as her body twitched with each orgasm, her eyes becoming glassy as they appeared to stare out into space. It was then that Mark heard Sara moan out with a tense release, " M.Ma.Mark.Mark.Mark." As he heard her calling his name, he could feel that it was too late for him. Before he had even grabbed hold of his cock, his balls began to release their load. At the instant his fingers wrapped themselves around his cock, his cum exploded out, shooting high into the air, clear across Sara's bed.
His fingers pumped the soft skin of his cock once and again he shot out, his cum landing across Sara's soft belly. The sight of his cum landing on her excited him even more and again he pumped himself, this time leaning forward to empty himself directly onto her.
His knees nearly buckled as he continued to come, releasing more, then more of his load onto her belly until he could come no more. Sara too, began to relax her body, flush with heat and sweat as she continued to rub herself, only slowing as her other hand released it's grip at her side.
Mark was too spent to even notice as he stood by her side, eyes now closed and his head tilted back, stroking his cock gently as it slowly softened. Mark slowly opened his eyes and looked down at Sara, and admired the view of his kid sister as she basked in the afterglow of her orgasm. He stood over her, admiring how engrossed she was in her own pleasure, and for a began to feel uncomfortably out of place.
He watched her as she continued to please herself, long after he was through, and how she seemed to be oblivious to the fact that he was finished; at least for now. He stood silently for a few minutes watching her, thinking about what had just happened when it occurred to him; this was her first time, her first orgasm. The realization struck him hard and he felt even more uncomfortable standing there; guilty, voyeuristically watching Sara discover the joy of masturbation.
And with that, Mark quietly he turned to leave, never saying a word to her as he returned to his room. Indeed, Mark's intuition had been true; but not on all accounts.
It was true that this had been the first time for Sara, true that she was so overcome by the experience that she hadn't noticed Mark's departure until he was gone. But as she heard the soft steps of Mark retreating from her room, Sara rested her head back onto her pillow, closing her eyes and letting her body relax fully as she gently massaged herself; enjoying the feel of her fingers as they rubbed her mound, and thought of Mark standing there by her side.
She brought her hand up to her belly feeling the warmth of Mark's slippery cum on her skin, and she ran her fingers through it; smearing it across her belly and between her fingers. The sensation was electric; the feel of Mark's orgasm spreading out over her belly, and she savored the musty smell of him. The thought of it was enough to fuel the thirst for another orgasm, and so again she began to rub. continued.
