Despite the thrill of having a pair of real naked tits in his hands, Robert managed to keep sight of the fact that they were Carla's tits. So when he started giving them some exploratory squeezes and saw her grimace slightly, he immediately reduced the pressure he was applying so he didn't hurt her. It took him only a moment to decide that he really liked breasts-particularly Carla's. They were somehow soft and firm at the same time, and delightfully smooth and warm in his hands. He happily spent considerable time just running his hands over them, gently squeezing them, and enjoying how they felt in his hands before moving on to find out what he could about her nipples. To his surprised pleasure, he found that he could softly tease the firm cylinders and roll them between his fingertips and get them to grow even longer as he watched the dark brown rings surrounding them pucker in sympathy. It was a fascinating sight to go along with the more tactile pleasure he was getting.
Other than a single brief bit of discomfort, Carla was pleased with what her brother was doing with his hands: his touch was as gentle as she could have wished for, and he was somehow able to bring out sensations in her breasts that she'd never experienced on her own. Then when he started playing with her nipples, those feelings increased even more, and she could feel her nipples grow longer and harder under his ministrations. Completely forgetting that it was her own brother molesting her, and that the two of them had an audience, Carla felt herself begin to get aroused from what was happening to her developing mammaries.
Without being told to, Robert cupped his sister's breasts in his hands so that he left their peaks exposed, then leaned forward and took the end of one mound between his lips. Carla gasped in response, and when he started to suck on the woman-flesh in his mouth, her pleased moan was so soft that he was the only one to hear it, he was sure. It was short work for him to bring both of her nipples to full extension, glistening with his saliva.
Carla had never been able to bring her nipple and tongue together, never mind actually experiencing having any part of her boobs in someone's mouth. The feel of Robert's mouth around her nipple had been indescribable; when he actually began sucking, the sensation only got better… something she hadn't thought possible.
Robert was having the time of his young life when he heard their captor tell him "I think you've had enough fun, junior. Now it's time for you to learn something you'll like even better."
Reluctantly, Robert pulled his head and hands away from Carla's tits. He caught the brief look of disappointment on her face before turning his head to look at the man with the gun while he waited to hear what was next. He couldn't believe his ears when he heard the man ask "You've heard about eating pussy and blowjobs, haven't you?"
Feeling himself blushing and not trusting himself to speak, Robert nodded his head, prompting the man to tell him "Well, congratulations, kid; now you're gonna find out what they're all about."
Hearing that, Vic started to take a step and say something, but before he could finish either, the pistol was pointed his direction, and the man holding it demanded "You got something to say, asshole? 'Cause unless you're gonna tell us where to find what we're after, you best hold still and not make a fucking noise, got it?"
Quashing the desire to do or say something he knew was not only futile but would likely get him or one of his family hurt, Vic silently resumed his previous position. Still, there was no mistaking his anger and outrage as he listened to their masked master tell his son "To eat pussy good, you gotta wanna make the girl feel as good as she does for you. So you get into the right frame of mind, missy's gonna give you a blowjob first."
Carla turned her head to face the man, plainly surprised and disbelieving what she'd just heard. She was still looking at him when he told her "That's right, missy-you're gonna take your brother's dick between those pretty lips of yours and suck him off. You're gonna make him cum in your mouth, and you better swallow every drop of it, too… or else I might be tempted to think that you don't like his dick, and shoot it off. Got it?"
Terrified at the idea of Robert getting shot at all, never mind there, Carla softly answered "I understand."
Even hearing the threat of having it shot off his body wasn't enough to make Robert's cock flag even a little bit; the idea of having his hard penis in something other than his own hand was simply too much.
Standing there, he watched as Carla turned to face him before slowly sinking to her knees. A few seconds passed before she reached out and hesitantly cupped one hand under his scrotum while the other took tenuous hold of the base of his member. Doubting that anyone else could see, Robert could feel his sister slightly hefting his balls in her hand as though trying to guess their weight before she carefully (and gently, much to his relief) explored their size and shape. Apparently satisfied with what she learned, she turned her attention to performing a similar exam of his hard cock. When she was done, she leaned forward and gave the head of his manhood a tentative lick; a moment after that, she opened her mouth and took him between her lips.
Although she wasn't happy about what she'd been told to do, Carla wasn't what anyone could call disappointed about it, either: she'd been wondering what a real adult penis looked like, and although her brother wasn't quite an adult yet, he was certainly big enough-both in age and physical development. When she knelt down in front of him, she was getting an opportunity that she'd only dreamed about before then. Not daring to delay too long, she still took a few seconds to really LOOK at Robert's hard penis, it being both the first she'd ever been that close to and the first erection she'd seen.
Despite the circumstances, she couldn't help but feel a little thrilled by what she saw; after she got her hands on him, that thrill got even stronger. Raising the hand under his sack, she felt a mild surprise at how light it seemed in comparison to how big it looked; her tactile exam of its contents told her that his balls were generally shaped like the drawings she'd been shown in the Sex Ed class she'd had. Despite the gentle grip she had on his cock, she could still tell that it was incredibly hard underneath the smooth skin she was touching. Slightly awed by the size of it (her hand barely wrapped around it, and its width didn't extend even halfway down the length of it), she was amazed to realize that she wasn't afraid of the idea of something that big being inside her… knowing that a baby came out of the same place reassured her that the seeming monster she held would go in even easier.
Knowing what she had to do, Carla leaned forward and took a hesitant taste so she could prepare herself for actually having it in her mouth. Relieved to find that it didn't have any appreciable flavor, she did what she knew she had to and simply opened her mouth and took in what she could comfortably fit. She'd heard older girls talking amongst themselves, and read and heard enough other things to understand that "blowjob" was a misnomer; remembering what she'd already learned, she began putting it into practice and applied a gentle suction to the shaft that extended between her soft lips. With her hand still gripping the base of Robert's erection, she was able to keep him from thrusting himself even farther into her mouth-something that told her she was getting things right. As she continued to recall different bits of conversation she'd overheard, she began applying the details from them: using her tongue at different places and in different ways on her brother's manhood, changing the gentle suction she was applying in different ways, and even starting to slowly bob her head on him.
Having his sister's warm, wet mouth surrounding half his dick had left Robert stunned at how good it felt. When she'd started to suck on him, the desire to feel even more of the sensation was more than he could deal with; it was only the realization that it was Carla's hand around the base of his cock holding him back kept him from trying harder to stuff himself into the delightful confines of her mouth. Then when she started doing things to him, too… he knew that there wasn't a damn thing he could do to keep from climaxing in her mouth; all he could do was try to put it off for as long as possible. That met with only marginal success, and when she started moving her head on him in addition to everything else it was simply too much for him to bear. He knew she couldn't have shifted her head back and forth a dozen times before he felt his balls start to pull up; a couple more times of her lips sliding up and down his shaft, and he erupted.
From the way Robert was acting, Carla knew something was going to happen, but she wasn't prepared in the slightest when his cock suddenly filled her mouth with his juice. Although she was startled by it, she had enough presence of mind to keep going while quickly evaluating the semen he kept squirting.
Even though she wasn't wild about the consistency or taste of it, she expected that was mostly due to having never tasted it before. After she had the time to get used to it, she decided that it really wasn't all that bad, and didn't have any qualms about swallowing it as she'd been told to. By the time his cock had stopped pulsing in her mouth, she'd actually started to kind of like the taste of her brother's cum, and surreptitiously used her lips to milk his shrinking shaft of any remaining drops as she slowly pulled her head back before letting him slip from her mouth. As she moved to stand up again, she proved she'd done what she was supposed to by saying "There, I did it", only to hear the man with the gun say "You sure did, missy!", with a brief laugh.
When asked "That was pretty good, wasn't it, kid?", Robert was ashamed by his enthusiastic "Yeah!"
"Well, the next part don't feel as good, but it's almost as fun", the armed man said. Directing himself to Carla, he said "Okay, missy, time for you to sit down and spread 'em so Junior can get his licks in!", drawing laughter from the two men behind him. Despite feeling herself blushing, Carla tried as best she could to maintain her composure as she sat down in one of the armchairs and moved her legs apart- only to be told "Nah, not like that. Scoot forward so your ass is on the edge and hang your legs over the arms. You don't want your brother gettin' a crick in his neck, do ya?"
It was only a few moments until Carla was positioned to the man's satisfaction, causing her to blush even harder at knowing the sight she presented to everybody.
Seeing that his sister was ready, Robert wasn't surprised when the man told him "Go on, kid. Get your face in there and find out what fresh young pussy tastes like. Trust me, it's good!"
After moving in front of the chair Carla was in, Robert moved to sit on the floor; as low as the chair was, he knew he wouldn't be comfortable kneeling, and he suspected he was going to be there for a while. Though he didn't know it, Robert's attitude closely matched his sister's: as much as he hated being forced to do things with his own sibling, there was also part of him that welcomed the chance to learn and do things he'd heard of and wondered about.
With his head that close to Carla's exposed pelvis and crotch, the young man had the opportunity to get his first good look at the details of female genitalia-and found them lovely, to his surprise. Carla's bush wasn't as large or thick as his, making it possible for him to see the surface of her mons; with her sitting the way she was, he didn't have any trouble identifying the small bump at the top of her slightly parted cleft as being her clitoris. Flowing down from it were her inner lips, thin and small and looking incredibly soft. At the bottom, between them, he could see the entrance to her vagina; with her legs spread the way they were, she was opened up enough for him to make out what looked like a small ring inside her. Thinking back to some of the diagrams he'd seen, it took him only a moment to understand that that ring was her hymen… the maidenhead that defined her virginity. The entire area around her opening looked shiny to him, though he didn't know the significance of it until he heard one of the other men exclaim "Hey, it looks like missy's already worked up a little bit!"
Recalling the disappointment he'd seen on Carla's face (and what she'd done after he'd cum in her mouth), it dawned on Robert that his sister might be glad about what they were doing the same way (and for the same reasons) he was. Awakened to the possibility that Carla wasn't a completely unwilling participant, the young man silently resolved to do as much for her as she'd done for him.
After mentally reviewing the little bit of factual information he had about cunnilingus, he leaned forward; when his head got close to his sister's pelvis, he got his first whiff of a singularly enticing aroma. After a couple of seconds, he understood that what he was smelling was the liquid that was making Carla's opening and labia shine. Knowing that it was the scent of her arousal only added to the appeal of its slightly musky and somehow sweet overtones, and made him eager to find out if her juices tasted as good as they smelled.
Extending his tongue, he drew the end of it across her opening and got his first taste of essence of emale-and fell in love with it. Carla's taste wasn't exactly the same as the smell, it was somehow better. He repeated his actions, and extended them by drawing his tongue up between his sister's labia for a little ways. Another pass of his tongue ended only after he'd made careful contact with her clitoris, which drew a soft noise of pleasure from her. Robert didn't think anyone else could see what had happened, but he'd felt Carla lifting herself up slightly to increase the contact between his tongue and her pussy… something that told him she liked what he was doing.
Carla had felt mixed emotions as she'd watched Robert's face approaching her pelvis. That she'd finally find out if having her pussy "eaten" was as good as it sounded like it would had her feeling eager anticipation, while she was deathly afraid that her brother wouldn't find her taste and smell as appealing as she did. Much to her relief, his reaction after his tongue touched her the first time was enough to reassure her that she wasn't gross or disgusting there. When he'd progressed to touching her clitoris with his tongue, she couldn't help trying to increase the pressure at least a little bit. She hadn't been masturbating that long, but she'd definitely learned how much pressure felt best to her.
Though she hadn't meant it as a signal, Carla knew that Robert had noticed what she'd done when his next contact with her clit was firmer than the first; since the second wasn't as firm as she liked, she tried pressing herself up again. It apparently worked, because when Robert began using his tongue on her clit again, it was nearly perfect. Between what he was doing to and with her clitoris, and the way he was using his tongue at the entrance to her vagina, Carla was receiving more and better stimulation from Robert than she'd ever managed to give herself.
Robert had been worried that he wasn't pleasing Carla when he felt her press herself up against his tongue a second time, but she didn't do it again; when he realized that she was beginning to get even wetter than she'd been before, his fears were completely assuaged, leaving him free to enjoy what he was doing. The taste of his sister was a treat for Robert's taste buds, and knowing that he was arousing her just by using his mouth on her left him feeling rather pleased with himself. It wasn't long until he was totally focused on what he was doing between his sister's thighs.
Vic and Ellen had both watched the initial intimacy between their kids with horror and anguish, but as it had progressed, their reactions had gradually changed.
As he'd watched Robert's actions with his sister, Vic had gone from outrage at what his daughter was going through to consoling himself that at least Robert wasn't doing anything to hurt Carla. But the longer he stood there looking at his nude daughter, the more insistent the little voice in his head telling him how pretty she was became. Then the damn thing started pointing out how sexy she looked, and how she was responding to what her brother was doing to her-pointing out things that he'd willfully ignored: the faint flush she'd developed, how the ends of her breasts had erected and how hard her nipples had gotten, how willingly she'd sucked her brother's cock, and then how wet she was even before Robert started using his mouth on her. His reluctant awareness of her as a sexual being, grown and developed enough to engage in (and plainly enjoy!) the things their captors were having her do, combined with the sight of her lithe naked body to have him starting to feel a vague desire… the target of which he was unwilling to examine too closely.
Ellen had started with feeling great sympathy for what Carla was going through-at least until she realized she was looking at her son's erection waving in the air and thinking how much she'd like to feel something like it inside herself. She and Vic hadn't had sex in several weeks; since shortly after they started arguing, in fact. While she would have admitted that she wasn't what could be called "passionate", she'd still come to miss the pleasure and release of sex more and more as the weeks had gone by. The first few times she'd looked at her naked son's equipment, she'd told herself that it was simply a normal motherly concern that her son was developing the way he should. But she kept looking more often, and for longer periods of time, and had to change her excuse to concern about what would happen to Carla if the men that had invaded their home demanded that the two teenagers take things too far. When Carla had been obliged to fellate her brother, Ellen hadn't noticed the increase of saliva in her own mouth, or that she was unwittingly doing things with her mouth and tongue as though SHE was the one with a penis in her mouth. Only when she watched Robert filling his sister's mouth with his semen did she realize that she was imagining the taste of cum on her own tongue… something that gave her no small thrill, despite the circumstances they were in.
Then Robert had been told to use his mouth on his sister, and Ellen couldn't help watching in anticipation as her children moved to comply with the demands of their captor; when her son had first touched his tongue to his sister's womanhood, Ellen could have sworn that she felt the sensation of it on her own genitals. Unbidden and unwelcome, her mind conjured up the image of Robert doing that to her, leaving her ashamed of herself-but unable to push it out of her thoughts.
She was so attentive to what her son was doing to her daughter that she almost didn't hear the man with the pistol tell her "While Junior's finding out how good his sister tastes, mom, why don't you show missy what she should be doing when she gives blowjobs? It's starting to look like dad would like that."
Glancing over to her husband, Ellen saw that his cock had indeed gotten longer and heavier, though he wasn't anywhere near having an erection. Her initial disgust that he was getting aroused was short-circuited by her shameful admission that she'd been feeling the same way.
She didn't start moving soon enough for the man with the gun, and when she saw him start to point it at her, she hurried to comply with his "suggestion". Moving in front of her husband, she knelt down on the floor before reaching out and taking him into her hand. After lifting the firm mass of his cock up, she leaned forward and took the head of it between her lips. As she started to use her tongue on him, she heard one of the men say "You're supposed to be showing missy how to give head, mom, so the idea is make him cum hard, not fast."
With her husband's cock in her mouth, Ellen could only nod her understanding before resuming her efforts. Remembering how adventurous and passionate the two of them had been when they were first married, she knew exactly what to do to get Victor erect.
Ashamed that his arousal was enough for their captors to notice, Vic felt a relief that he'd never admit to when he heard one of them tell his wife to use her mouth on him: he missed the sex with his wife more than she did, and it had been a long time…
It was a considerable pleasure and relief to him when he felt Ellen's warm, wet mouth surrounding the end of his dick. It got even better for him when she started doing the things she'd done while they were still newlyweds. Only a couple of minutes passed before she had him fully erect, and was slowly sliding her lips up and down his shaft. Closing his eyes, he tried to focus his attention on the feel of his dick in her mouth-but it wasn't long until the face he saw moving back and forth on his shaft was that of his daughter, not his wife. He managed to push the image away, but it kept coming back; each time it did, it became clearer and stayed longer… and aroused him even more, to his dismay.
Ellen could tell that Vic was getting excited faster than she'd expected, but simply attributed it to the fact that they hadn't been intimate for so long. She had her own trouble with the thought that it was Robert's cock she was sucking, not her husbands, and the inordinately higher desire she felt as a consequence.
Carla had had her eyes closed since shortly after Robert started licking her, her attention entirely on the incredible feelings he was creating. So when she opened her eyes again, and glanced over to see that her mother was kneeling in front of her father and doing to him what she'd done to Robert, it came as a considerable surprise to her. It also aroused her tremendously, since she'd had the normal crush on her daddy for years, and even masturbated to vague thoughts of the two of them "together". The angle they were at, she could easily see how long and big her father's penis was, and how it shined with saliva as her mother moved her head back and forth on the end of it. Remembering how Robert's penis had felt in her mouth, it wasn't difficult for her to imagine what her mother was experiencing… and Carla felt herself become incredibly aroused as she imagined what it would be like to be able to suck her father's erect penis herself.
His head between his sister's thighs, Robert was almost overjoyed by the sudden increase in the amount of liquids escaping Carla's vagina. Despite his focus on what he was doing to Carla, and how she was responding, he'd vaguely heard what his mother had been told to do; when he hazarded a brief look toward where his parents were, he wasn't quite as surprised to see what was going on. But he didn't find it any less exciting, and was surprised to feel his cock starting to grow again.
The next several minutes went by quietly, the silence broken only by an infrequent soft slurping sound or a restrained noise of pleasure. Ellen's mind kept toggling back and forth between visions of fellating her son and remembering that she was supposed to be pleasing her husband as best she could. In front of her, Victor was fighting a losing battle against the imagery of his daughter being the one with his hard cock between her lips, and the shame and arousal he felt from it.
A short distance away, Carla was occupied with enjoying the feel of her brother's mouth and tongue doing such wonderful things to her pussy and clit while fantasies of sucking her father's cock played through her mind… and further fueled her passions. Between her wide-spread legs, Robert was busy cycling between trying to stimulate his sister into producing even more of her nectar for him to lap up, and stealing glances over toward where his mother's head was bobbing back and forth on his father's shaft while his own penis continued to grow longer and harder.
The silence was finally broken when Vic lost his fight to keep the images of his daughter out of his mind; with a deep groan, he began erupting into the warm, wet cavity his dick was in. His release was made even more intense by the thought that it was Carla's mouth, and not his wife's, that was receiving his cum.
Even though her eyes were closed at the time, Carla knew that the sound she heard was her father; almost immediately, she knew it signalled that he'd reached his climax. Knowing that he was cumming, it was easy enough for her to imagine that hers was the mouth he was filling with his cream- particularly since she still had the taste of her brother's semen still on her tongue. The visualization of his cock spurting in her mouth was enough to push her over the edge into the strongest climax she'd ever experienced.
Robert had heard the noise, too, and seen his father's cock and balls pulsing as they repeatedly squirted jism into his mother's waiting mouth; what surprised him was when Carla climaxed, too, so soon after their father did. Disappointed when her clitoris suddenly disappeared back under its hood, Robert found consolation in the sudden supply of his sister's oils for him to lick up; it took a few passes of his tongue before he realized that what he was doing was making Carla's release not only stronger, but last longer, as well. The thought that he'd successfully pleased his sister after what she'd done for him left him feeling satisfied with himself… and finished the job of getting his cock fully erect again.
