A Great Reason to Have a s****r!!! (Part 4) SeXStoRY

Soon Jamie's moans were joining Chris's, as he watched Heather tormenting and pleasuring her boyfriend's cock, wishing fervently that it were his. "Do you want to feel my mouth," he heard her say, "would that feel good, honey?" "Oh my god yes!" Chris panted, "please, oh god yes!" "Are you sure? Do you want more of this?" She delicately traced the tip of her tongue up the underside of his shaft to the head, where she softly flicked from side to side just below the rim. Looking up at Chris, she pouted and took little nibbling sucks on the head of his cock, allowing her lower lip to gently massage the underside, but always quick, brief, tantalizing. Jamie was now stroking his cock in earnest, terrifically excited by Heather's coy oral treatment of Chris's cock, and aching with envy. But then she did something that drove him almost mad with lust and frustration. As she worked on Chris's enflamed penis, licking, sucking, squeezing and teasing it to death, she looked straight into the camera and gave Jamie her full attention. As her tongue fluttered rapidly on the cleft under the swollen, purple cock head, she winked and raised her eyebrows as she stared out at the camera. Her meaning was simply to indicate to Jamie that she wanted him to pay attention to what she was doing so that he could give her his opinion of her technique later. But to his inflamed imagination her gesture was a maddening taunt – it said, "How'd you like me to do this to you – think you'd like this? Just think about how it would feel – think about it a lot!" Still looking into the camera, Heather held Chris's cock upright in her hand and began to lick gently all around the head, and gave it little sucking kisses. At the same time, she lightly stroked his balls with her fingernails. Chris was gasping and moaning in ecstasy at this treatment, but Heather kept her eye on the camera. She bit her lower lip, then rounded her lips into an "ooooooo". Her intent was simply to let Jamie know that the little trick he had taught her was really working – listen to Chris, Jamie! But the message Jamie got was again a mocking taunt: "Ohhhh isn't it driving you crazy to watch this? Bet you know just how it feels! You need it so much, don't you? Aww, too bad it's for my boyfriend, not for you..." Jamie knew that Heather didn't mean what he was imagining, but her facial expressions were so maddening, and excited him so much, that he allowed himself to be sucked into the illusion that she was actually taunting and frustrating him deliberately. He loved how it made him feel, and he teased and tantalized his own cock to intensify the torment. After a while Heather decided that she'd shown Jamie enough to pass her "final exam". She winked and waved goodbye to the camera, then stood up to get onto the bed. Jamie's view was now of her knees and thighs, and he watched as she pushed her nylon panties down her legs. She tossed the panties on the chair, deliberately covering the lens of the camera. Jamie's view was now just an amorphous blur of white, but Heather had forgotten the microphone, so that he could hear her as she joined Chris on the bed. He knew that Heather was now going to start fucking her boyfriend in earnest, and that made him sick with jealousy. But he couldn't bring himself to turn off the computer, so he sat back in his chair and closed his eyes, slowly stroking himself as he listened to the sighs and moans of the couple in the other room. Amidst the sounds of passion and pleasure he made out Heather's voice – "You like me on top like this, honey? This turns you on? ... Ooooo yes, suck them, ohhhh Chris, that feels so good! ... Oh yes, right there, ohhhhhh don't stop, don't stop, oh god, oh god, yesssss..." Finally, Heather's cries as she reached orgasm, followed quickly by Chris's moans of pleasure and release. After that there were muffled sounds of talking and affection as they got dressed. Soon they were gone, and Jamie was alone in the apartment once more. He turned off the computer and got into bed. He was tremendously excited, and masturbated desperately, whimpering, seeking relief from the lust and frustration the scenes he had just witnessed had caused him. He was agitated and exhausted, his mind a confused tumult of jealousy and lust, of indecision and desperation; he was a mess. * * * * * Jamie hadn't heard Heather come in. Even though he had had trouble falling asl**p, he evidently finally managed to drift off before she got home. He got up late in the morning, but she was still in bed. He made coffee and some breakfast, and tried to read the Sunday paper. He put it down when he realized that he was re-reading the same sentence over and over. His concentration just wasn't there – images of Heather's oral sex tease totally consumed his brain. He had masturbated several times during the night to the memory of her performance, but it still held him – if anything, he had become even more obsessed. Heather finally appeared at about noon. She shuffled into the kitchen to get some coffee (Jamie always made enough for both of them), then went into the living room. She was still in her usual sl**ping attire, t-shirt and panties. She yawned. "Hi, b*o. Unnnnhhh, I'm so sl**py! You sl**p OK?" "Not bad," he lied, "considering I had an interesting interruption last night." She giggled. "It really worked, didn't it? We pulled it off! So, what'd ya think? I did good, right? Just like I said? You proud of your prize student?" "You were incredible," he said. He was trying very hard to be up-beat and cheery with her, even though he was roiling inside, in utter turmoil over his lust for her. "You were very hot – Chris is a lucky guy." She grinned and ran over to the couch and plopped herself down next to him, squeezing his arm affectionately. "It was so much fun," she said excitedly, "especially since I knew you were watching. So kinky! I really wanted to show you that I had been paying attention to you when you were telling all that stuff about guys. Did you see all the things I did? Everything worked just like you told me it would!" Jamie smiled weakly, trying to match her enthusiasm. But having her pressed up against him as she was, in her tantalizing underwear, was taking its toll on his ragged emotions. He felt himself getting excited once more, but in his present state this was more upsetting than arousing to him – he was rapidly approaching the limits of his endurance. He didn't know how much more he could take. Heather didn't notice any of this. She chattered away happily, unaware of the distress she was causing her b*****r. She took one of his hands and held it in front of her, palm upward. "Did you see when I did this? It was sort of what you talked about, but not exactly..." She lowered her head to his hand, and proceeded to flutter her tongue back and forth along his index finger, mimicking what she had done to her boyfriend's penis the night before. Jamie closed his eyes and groaned. It was the last straw. The weeks of unrelieved sexual excitation he had experienced since she moved in with him, the tantalizing displays and unconscious teasing, not to mention the deep obsession he had developed for her as he watched her grow into a tempting young girl, finally became too strong to be suppressed any longer. The dam burst. "Heather! Stop, please! For god's sake, stop!" He jumped up and stumbled away from the couch. Heather looked at him in shock, frightened. "Jamie, what – what did I do ...?" He was in total anguish, almost sobbing. "Do you have any idea what you've been doing to me, how you've been making me feel? Do you?" He was pacing up and down across the room, wringing his hands, and running them through his hair. "You have been driving me crazy, absolutely fucking crazy! Can't you see that? Oh my god, Heather, the way I feel about you – don't you ... do you have any idea how I ... oh god, I am so fucked up!" He turned to face her. "I'm so sorry, Heather, it's not your fault, I am just so messed up – I have really screwed things up!" He continued pacing, getting more upset. "All the time we were k**s, ever since you grew into that ... that incredible body of yours, I have just been so hot for you! Oh, I'm so sorry, I shouldn't be saying this to you, Heather, but it's the truth! I've been in love with you for as long as I can remember – no, that makes it sound so pure, so nice – in lust with you, Heather, I've been in lust with you! I can't count the number of times I've jerked off thinking about you, thinking about how badly I wanted to touch you, to make love to you! Oh I know it's not right, you're my little s****r, almost my s****r anyway, and I shouldn't think about you like that – but I just can't help it! And here, having you here, seeing you every day, seeing you like that, almost naked in front of me – ohhhh Heather it's been driving me nuts!" He continued pacing. "My god, when I think of some of the things I wanted to do with you, some of the things I almost did!" He couldn't bring himself to tell her about actually fondling her in her sl**p, or peeking at her in the shower. He stopped in the middle of the room, looking down at the floor, slowly shaking his head. "Oh, I have really messed things up now, a total fuck-up – Heather, I shouldn't have said anything – I'm so incredibly sorry, s*s – just ... just forget I said anything..." Without looking at her he grabbed his jacket and quickly walked out the door. Heather sat frozen, her mouth open, her eyes wide, staring straight ahead. She was totally stunned, in shock. * * * * * Jamie caught a bus downtown. He didn't know what to do – he just wandered around aimlessly, feeling miserable. He walked across the campus of the University, then up the hill through the park, trying to think things through. What a mess he'd made of things! He'd ruined his relationship with his s****r, he was sure of that – after what he'd said to her there was no way he'd be able to redeem himself in her eyes. This made him so sad, because he really did love her. Why did he have to be this way, why was he such a perv? Night fell, but he felt no desire to return home. Walking along the boulevard he passed a strip-club, and went in for a drink. Maybe if he got turned on watching the girls here it would take his mind off his troubles. He got a whiskey at the bar and sat down at a table to watch, hoping to get excited. He didn't. As the girls taunted and teased, slowly removing their clothes, the other men around him were breathing heavily and drooling, but he was unmoved. None of the girls interested him – except for one. She was starting to get to him, and he settled back, becoming aroused – then he realized with a start that she reminded him of Heather. In despair, he got up and left. He knew that he had to go home eventually. He was dreading seeing Heather again, but he had to face the music sometime, so he might as well get it over with. Even worse was the thought that she'd probably left – he realized that that was more than likely. She's gone back to Mom's, she'll tell her all about what a perverted jerk Jamie has turned out to be – they'll probably never speak to him again. He was feeling very depressed. * * * * * It was late when he arrived home. The apartment was quiet and dark – so she really has gone, he said to himself. Alone again. He was too upset to eat, but he felt grungy from wandering around all day, so he took a shower and went straight to bed. He didn't bother with pajamas – he just crawled into bed naked and miserable. He lay staring at the ceiling, reluctant to attempt sl**p, knowing that his thoughts would keep him awake, tormenting him. Finally, he sighed and reached for the light – but stopped when he heard a faint knock on the door. Surprised, he raised himself on his elbows and listened. "Jamie? Can I come in?" After a moment the door opened slowly, and Heather peeked in. "Is it OK?" Jamie was surprised and apprehensive. "Yes, I ... I guess so." Heather moved shyly into the room. She was wearing a white terrycloth cotton bathrobe. "Hi," she said. "Hi," he answered. Then, "Oh, s*s, I'm so sor..." "No, Jamie, stop," she interrupted. "I'm the one who should be apologizing to you. I've been so stupid, so incredibly stupid! Stupid and blind." She moved further into the room, holding her arms. "I had no idea, Jamie, really I didn't! And when I think back to the way I acted with you, and the ... the things I did around you – oh, Jamie, I'm so sorry! It must have been so difficult for you." She lowered her arms and opened her hands, entreating. "I would never do anything to hurt you or be mean to you on purpose! You know that, don't you, Jamie? You're my b*****r, and I love you so much!" She looked towards him earnestly, almost pleading. She moved to his desk chair and sat down facing him. "All these years," she continued, "and I had no idea you felt that way about me! When we were k**s it never occurred to me to think of you as ... as a boy. Other boys used to like touching me, and it was fun getting them excited, but it never entered my mind that you might have feelings like that, too. Oh, man, was I dumb!" She struck her forehead with the palm of her hand, and shook her head in disbelief. "And then when Mom suggested that I come stay with you, I didn't want to at first, 'cause I thought I'd be imposing – come on, Mom, I said, he doesn't need to have his little brat of a s****r barging in on him! I was so afraid you'd resent me for being a burden." She got up and started pacing the room, with her hands on her hips, shaking her head. She smiled ruefully. "When I think of the way I paraded around in front of you wearing practically nothing, and the things I'd talk to you about - and now knowing how you really felt – oh god, I just want to die of embarrassment!" She blushed and covered her face with her hands. "Here I thought I was just the silly little s****r, chattering to her big b*****r as if he was one of her girlfriends – and I now I find out that what I really was, was a nasty little tease! 'Cause that's what I was, wasn't I Jamie? A nasty little sex tease – I didn't mean to be, but I was." Jamie broke in. "Oh, no, Heather, don't say that! You didn't know." She was silent for a few moments. Then she looked at him and smiled. "But I do now, don't I? In the past few days I've learned all sorts of things about my big b*****r. I really want to make it up to you for making you suffer so much. I want to show you how sorry I am, and how much I love you." She got up and walked behind the chair, resting her hand lightly on its back. "You know, Jamie, you are really a very good teacher. You've taught me quite a lot about ... about what men like." As she was speaking, she began to untie the sash of her robe. "And about what you like..." She stepped out from behind the chair and opened the robe, letting it fall to the floor. Jamie stared at her, shocked beyond words. She was dressed in a very short, bright red negligee, sheer and transparent, and a pair of black stockings, held up by a lacy black garter belt. "I went shopping today," she said softly, smiling. "Do you like it?" He was unable to speak, but he didn't have to – a bulge was rapidly becoming visible through the thin sheet that covered him. Heather noticed. "Oh, yes," she purred, "I'd say you like it. I'm glad – it's for you." Running her hands sensually up the contours of her body, she slowly moved to the bed. Smiling at her b*****r, she grasped the sheet and slowly drew it down, uncovering him completely. His cock was fully erect, extending upward along his stomach, rigid, quivering. Biting her lower lip, she shook her head gently in admiration. "Oooooo," she cooed, "my b*****r is such a beautiful man – just beautiful!" She bent down and gently kissed him. He moaned as she slowly ran the tip of her tongue back and forth between his parted lips. She smiled and sat down next to him on the bed. "And all this time I thought I was just a silly little s****r – but what I actually was, without knowing it, was a silly little cock-tease. Is that what I am, Jamie? A little cock-tease?" She reached up and untied the neck of the negligee, letting it fall from her shoulders and down her arms, exposing her full breasts almost completely, but stopping just short of their tips. She smiled at him seductively, and licked her lips. "You poor boy," she cooed, "suffering like that." She began to run her fingertips along the inside of his thighs, caressing gently, moving ever higher, but slowly, slowly. "Seeing your little s****r in her little frilly underwear, lying all over the place with her legs spread – that was so nasty of me!" Her hand had reached his crotch, and she began to manipulate his balls, making slow circles around his scrotum with her fingertips, lightly, delicately. "And I guess some of those little t-shirts I wore were pretty revealing, don't you think? Did that tease you too, Jamie? Did it?" He was speechless, overwhelmed by the sight of her voluptuous body, tantalizingly displayed to him in the loosened negligee, and the maddening sensations of her hand on his balls. He moaned, and looked at her pleadingly. Her fingertips were now gently flicking back and forth along the ridge on the underside of his shaft, moving gradually higher, getting closer to his center of pleasure. "And last night – oh my, that must have been just torture for you to watch! Did you like seeing me do those things to Chris? You were wishing that I was doing it to you, weren't you? He was getting all that pleasure, but all you could do was pretend it was you - awww, poor Jamie!" She looked at him with a little pout. "How can I ever make it up to you?" Her fingertips were now lightly brushing along the sides of his cock, missing where he needed to be touched by a fraction of an inch. Jamie groaned, in an absolute agony of lust and frustration. "Oh god, Heather, please, I – ohhhhh..." She put a quieting finger to his lips. "Shh," she said, "you don't have to say anything. I know all about what you like, Jamie – you taught me, remember?" She smiled and blew a little kiss towards him. "I'm going to make my big b*****r feel sooooo good..." She gently grasped his cock, feeling it warm and throbbing in her hand. She looked at him, her eyes wide and innocent. "After all," she whispered, "what are s****rs for?" And then, lightly and slowly – very slowly – she began to stroke...
