juujin was looking forward to the week-end with his family as he turned the last corner before arriving. As a third year medical school student, the 24 year old missed his parents and little sister. He wouldn't admit it to her, but he did miss Lily quite a lot even though she could, sometimes, be a pain. She would probably leave home for college next year, at nineteen, and sometimes he wondered if it would be a good idea to ask her to come live with him. He shook his head and forgot about that as he knocked and opened the door. He was warmly greeted by his parents. Lily wasn't there, but he knew she'd arrive later. Ben spent a few hours with them until the moment, around five, Lily arrived. Ben's heart skipped a beat when he saw his sister bouncing up the stairs. Ever since she had bloomed through her teenage years, Ben had been secretly attracted to his sister. For a while that attraction had been so powerful that he had remained single for a year and a half! Lily seemed as lively as ever as he watched her through the large window, her two braids bouncing behind her as she ran to the door. She exploded into the house, there was no better word for it, and threw herself into his arms. Lily had always been full of life and energy. As he squeezed her hard, eyes closed with a grin on his face, Ben took a deep breath and took in her unique scent. She kissed him on the cheeks before sitting in front of him at the table to catch up on news. As they talked Ben had to work to focus on what she was saying. He was spellbound by her long dark red hair, her faint freckles, he small nose and generous lips who were, as ever when she was around him, constantly smiling. But most of all, Ben had to confess as he stared at her, he was captivated by her bright blue-green eyes. She had incredible eyes that seem to sparkle under the merest light, and when she was in sunlight they were positively phenomenal. Lily sometimes said that she wished she had ordinary eyes as she was tired of the attention, tired of the fact that people bothered her continuously with compliments. But Ben knew she was lying: Lily loved her eyes. A while later, as she got up and moved around in the kitchen, Ben's eyes stole a few glances at the rest of her. Lily was on the short side of the average and was pretty slim all around: small sexy breasts, a tiny waist that made her lean hips seem bigger and long legs that were stronger than their slim shape would lead one to believe. Her short skirt, white knee high socks and tight tank top highlighted her slender shape. Overall, she looked like anime gifs a human female version of a cat. In the manga and anime world he really liked, he often saw girls cosplaying as cats. While he liked big breasts as much as the next guy, Ben thought that human rape hentai gifs versions of cat should look exactly like his sister: lean, thin and agile. Their evening together as a family, the first in a long while, was very pleasant. Yet as they talked Ben slowly observed that whenever his sister wasn't talking and thought nobody was looking at her, her smile faded. He had no idea why. Maybe she had recently broken up with a boyfriend? He didn't feel like asking her what was wrong right now, not in front of their parents in any case. Later that night, as he was lying on the uncomfortable sofa bed, he thought about Lily again, trying to figure out what could be wrong with her. Given that they didn't see each other often he sighed, knowing he couldn't divine it out of thin air. He resolved to find the time to ask her about it tomorrow. As luck would have it, he found himself alone with Lily for breakfast. When she walked hentai incest gifs in the kitchen wearing a tank top, and probably only that, Ben almost choked on his toast. She wasn't wearing any bra, that much was obvious, and he couldn't detect any panties under the tight fabric. The tank top covered, at most, a third of her thighs and the effect was remarkable. Lily had wrapped her hair in a high bun above her hair and he stared at her, his breath taken. He felt a surge of pleasure in his heart and an equally intense sure of blood between his legs. Ben bit his lower lip, closed his eyes and tried to focus his sharp mind on the fact that she was the last person he should have these kinds of feelings for. A deep breath later, he wished her good morning. Lily startled when she heard him: she hadn't seen him yet and had probably thought that she had been alone. But Ben felt both apprehensive and glad when Lily walked to the table and sat down wearing nothing but her tank top. He would have been relieved but disappointed if she had gone and changed, but now... now he had to deal with his futunari gifs inappropriate feelings. Instead of doing small talk, Lily surprised him with a question "I have a strange question for you, brother." She smiled, but without tentacle gifs preamble, asked "I know you like anime and manga, but do you like futanari?" Ben's eyes opened wide when he heard her question, and he managed not to spit his cereals all over the table. "What?" he asked after swallowing. "Are you serious?" "Yes. What, we're both adults?" "Yes, but..." Futanari was a genre of hentai creampie gif where females had huge cocks and, sometimes, males had breasts. It wasn't, at all, a subject Ben had ever thought he'd discuss with his sister. Especially not while she was practically naked in front of him! "Look, Lily... I do like it. But... anime fantasy gif" he paused, then added "why don't you tell my why you're asking me that? What prompted the question?" He was surprised by her reaction. Very briefly, he saw her expression change and she seemed afraid for a second or so. "No reason, just curious... I like it too tentacles gifs." She said quickly. But very soon she changed the subject and stood up to go back to her room. Ben was so surprised that he didn't even think to look at her lovely ass as she walked away. Why had she asked about that? Ben actually loved futanari hentai, either in manga or anime form. But damn! Talking about that over breakfast anime porn gif? What had gotten into her? Then he realized that their parents would be back soon and that she'd had no other option to talk to him alone. After he finished his breakfast Ben stood and was headed for her room when he saw their dad's car stopping in the driveway. Shit. No time. The rest of the day offered no other opportunity, but seeing that Lily was obviously feeling bad, he managed to find a minute to tell her that he was sorry for reacting strongly at breakfast. She brushed it off saying that it wasn't important, but Ben knew that it was. He was hoping that we would find ourselves alone later that night, but she decided to turn in early. So once again he found himself alone in the damned sofa bed, thinking about Lily. About half an hour later, he suddenly heard the door opening in silence. "Ben? Are you awake?" asked Lily in a very low whisper. "No, I'm not." he said sarcastically. "What's up?" he asked. In the pitch darkness she came and sat on the edge of the bed. "I have a question I need to ask you. A question to you as a med student." she whispered. "Two weeks ago I went to a party. A very peculiar party. Let's say there were strange people there, with strange, er... strange pills." "Oh. I see." She was curious about drugs. Even though Ben couldn't see her, he could sense that she was very nervous. "Go on." "Well, I took a few and had the most epic trip imaginable. Life changing, in fact yuri gifs." Ben smiled when he heard that she was smiling herself. She even giggled before continuing. She probably wanted to know what those pills were and if he knew if they were dangerous or not. But he was wrong. "So I probably spent a few hours in that small room, tripping with four or five other people." Then she paused and remained silent for a few minutes. Given that the silence was becoming awkward, I said "Go on Lily, I won't judge. If you're worried about something, please let me help you." "Hmmm." she said, but as Ben heard her take a deep breath, he knew that her smile was gone and that she was nervous again. "Mind if we go to my room to talk? I don't feel comfortable here, with our parents on the other side of the wall." "Sure..." he said. Ben stood up to follow her and saw that she was still wearing the same tank top as this morning. She probably slept with it every night. "Focus!" he thought. They went downstairs, went to her room and closed her door behind them. When Ben saw Lily jumping in her bed and slipping under the blanket, he frowned. That was another sign that she was nervous. Sitting on the edge of her much more comfortable bed, Ben waited for Lily to talk. She turned her little bedside lamp on, looked at him and said "Listen Ben... It wasn't my first time with psychedelic drugs, but this was weird... Promise you won't judge me?" "Yes." Ben said. "I know you must have had some psych classes, and learned that hallucinations reflect the innermost thoughts of the person." she said. "Yes, sometimes. But other times it's just random images that don't mean anything hentai gif." Ben replied. "Ok then." One last deep breath before she said "I hallucinated futanari for hours!" "Oh!" Ben said, finally getting an explanation! Unexpected, but an explanation nonetheless. "Shit! It was crazy!" Lily said. "I had seen a couple of anime with futanari stuff, but this was beyond my wildest imagination! At first I was an observer, seeing countless girls with dicks and guys with breasts having sex in endless positions and arrangements of two three, four or more people at the same time! Soon after that, I was pulled in and felt myself having sex with all sorts of hermaphrodites, felt myself penetrated in all of my holes, sometimes all at once..." When Ben's sister paused, he himself took a deep breath and cursed himself for not thinking of putting his pants on. As Lily talked, his mind filled with images from his favorite futanari hentai and his cock grew and grew. Looking at Lily, Ben saw that her nipples were both sticking clearly through the thin fabric. And she wasn't done. "Eventually, I felt a penis growing from my pussy, as if my clit was transforming into this monster of a cock, growing and growing until it reach ten or twelve inches and even more! I saw myself fucking girls while their cock were slapping against my belly, against my breasts... Shit! When I came, I felt my entire body glowing, felt myself turn into a sexual bomb of raw pleasure! I even had a furry tail!" Ben, closing his eyes and biting his lower lip again, turned slightly on the bed as Lily talked. His erection was painfully pressed against his boxers, threatening to tear through them! He wasn't anywhere close to being ten inches long, but right now his cock felt like it, trapped as it was in his boxers. He dearly wanted to release the pressure, but couldn't do it now. After a brief pause, Lily said "So, am I crazy, big brother?" Ben stared at her, looking right into her magical blue-green eyes, Ben calmed himself and said "Of course not little sister. In fact, I think I'd pay a lot to have this kind of trip!" "Really?" she said, laughing. Ben could feel her nervousness melting away. "Yes. I do like futanari, even if it's something I never thought I'd talk with you!" he laughed. And then she shocked him "Are you hard, brother uncensored hentai gif?" "What? No, no... Must be a trick of the light." Lily didn't reply, clearly unconvinced. Nevertheless, she seemed much better. Still, with his experience at listening to patients talk about their problem, Ben suddenly had a nagging feeling that Lily had something else to say to him. "Don't worry about it... Just enjoy the memories and make sure not to overdo those pills, OK?" he asked. Lily nodded, and judging by the way she was looking at him, he was now convinced that she wasn't finished. But she nodded again and thanked him. Ben got up, making sure to hide his erection from his sister and walked back to his room. On his back on the bed, he pushed his boxers down and grabbed his cock. He moaned as soon as he started jacking off, images of futanari filling his mind. But soon he was seeing his sister in his fantasies and he stopped. He had often been tempted to masturbate while thinking about his sister, but he had always stopped himself. "tentacles gifs" he had thought. And now in his mind's eye his sister had a huge cock between her legs and the temptation was even greater than usual. Ben had never felt any sexual attraction to guys, but couldn't deny that his fascination for futanari meant that one day he would have shoujo tachi no sadism the animation episode 1 3d porn online free sex flash animations to do some serious soul searching. He wasn't a homophobe, but neither had he ever thought of himself as bi. At all. Yet seeing those anime girls with huge cocks... Shit. But his sister? Fuck! Ben laughed on the bed, letting his cock rest against his belly for a moment. Would this be the first time he allowed himself to masturbate fantasizing about his sister? Ben was sorely tempted! But before he could make a choice, he heard his door open again. In a flash he pulled his boxers up again and pulled the blankets to his waist. "Ben? I need to tell you something else... Would you mind coming back to my room?" "Sure, no problem." he said, noticing the tension in her voice. "I'll be there in a sec." After she left Ben stood up, stretched, took deep breaths and tried to clear his mind. He couldn't walk to his sister's room with an erection in his boxers! But he was so focused on getting his cock down that as soon as he did, he went to join her, forgetting once again to put his pants on. And so as he sat on her bed again, he cursed himself a second time. "Ben... Shit, this isn't easy. Ben, is it possible that such pills could have physical effects on my shibari gifs?" Ben frowned, snapped into focus by her question. He was worried about Lily, because there were, indeed, drugs that could cause physical damages. "Yes, it is." he said calmly. "What are your symptoms..." "Well, it started the day after the party. I spent the day feeling a buzz in my body." "A buzz?" Ben asked magic anime gifs. "Yeah. I don't know how else to describe it. A faint buzz in my stomach." "Hmmm. Ok. What else"? "Well, I've been feeling a lot hornier ever since that party." she said in a small voice. "That's understandable, Lily. Intense climaxes like what you describe can have long lasting—" "A lot hornier Ben. I think about sex all the time." she added. And suddenly, his sexual mind was fighting to regain control over the medical student in him. "Oh?" he asked, trying to gain time. "I have to masturbate at least twice every day, and... Oh shit... This isn't easy lolicon." "Just go ahead Lily. Just say it." Ben said. Lily reached over and closed her lamp. In the darkness, she said "Well, ever since that futanari trip, my body has begun to change." For a moment, Ben wondered if his sister wasn't going to tell him that she had a cock. But no! That was completely crazy! "What do you mean?" he asked in what he hoped was a professional voice. "It's hard to describe... At first it was just weird feeling, sensations I'd never had before... Ohh hentai gangbang gif." When Lily moaned in the darkness, Ben's eyes shot wide opened. Was she masturbating? Impossible! Then he heard the sound of flesh rubbing against a blanket. When she started talking again he could hear her voice quivering. "And then after a while I felt this urge to masturbate. As I played with my clit, it began to swell..." Ben's rational mind tried to save itself one last time by acknowledging that a clitoris could indeed swell with blood when excited. But that help didn't last very long. "Oh fuck..." Lily moaned again, clearly this time. "And now, when I masturbate, my clit transforms into a cock... Shit, a very real cock." And at the same time, he heard a new sound that he nevertheless was very familiar with: the sound of a guy jerking off under a blanket. But it wasn't a guy lying next to him. Briefly he wondered if Lily could simply be teasing him, but even though that explanation made more sense than Lily growing a cock, the two siblings had never shared anything remotely sexual. This would be completely crazy. Then again... Suddenly, Lily grabbed his hand hentai gifs, pulled it under her blanket and guided it to her pussy. And her cock. Ben gasped when he felt his fingers closing on a hard cock. On a big hard cock. He pulled his hand away, then closed his eyes, trying to make sense of what was happening. He failed. Groaning censored hentai gifs and getting up, he paced the room, trying to decide if he wasn't drugged himself. Had someone given him a dose of something? Impossible! But so was this! So was his sister growing a cock! Fuck! Sitting back down, he looked at his sister. Her eyes were now glowing in the literal sense of the word. He blinked, then looked again. Now her eyes looked normal. Well, blue-green, but normal for her. "What the fuck is going on?" he wondered. "Lily..." he said. "What... How... fuck. This is impossible! Even with genetic modification, it couldn't grow so quickly. And in any case there's nothing, not even cutting edge research that could do this... Shit!" He knew his mind was running around in circle. Ben reached under the blanket again and touched his sister's cock. It was bigger than before. When she moaned, he was reminded that she wasn't just a curiosity lying on a lab table. It was his sister and she was both nervous and sexually excited right now. Ben closed his eyes for a moment and took a few deep breaths. "Lily. Can you describe the pill and anything you can remember about that party rape hentai gifs?" She did. As she talked, he pulled his hand away from her cock, but let it rest on her thigh. As she talked, she kept masturbating herself slowly. She said it was to keep it there. If she stopped it would disappear, be absorbed into her again. This entire situation was completely unreal! Ben realized that it would be unreal even if she didn't have a cock: earlier today he had been uncomfortable about the fact that he was lusting after his sister, and now he was listening to her talking, with a hand on her thigh while she masturbated. Crazy enough even without the unnatural cock! When she was done, Ben shook his head, having learned nothing that could help him figure this out. He sighed. "And, er, the rest of your, well..." "My pussy?" she said in a small voice, and Ben felt a spasm of sexual pleasure between his legs. "Yeah. Is it, normal tentacles gifs?" "Yes. I think so. Can you check?" she asked, still in that small voice. Shit. Ben shook his head, but pushed his hand up. After having found the cock, Ben moved his hand down and felt his fingertips touching his sister's pussy. No balls at all. Before he could stop himself, he moved lower still and pushed one of his fingers inside her. Lily's pussy was drenched, more than lubricated enough to let his finger go as deep as it would go. Ben shivered with pleasure as he fingered his large breasts hentai gifs sister. Lily moaned when his fingers slipped inside her pussy. Moving his hand back up, Ben lightly closed his fist around the shaft of that impossible cock and kept moving up. Shit! It was big! At least eight inches! As if reading his mind, Lily said "And it can grow much longer than that..." "How long?" Ben asked, entranced. "Longest so far was twelve inches." "But that's insane!" he said. "I know..." she replied, but she was moaning, enjoying her brother's hand on her cock. "What happens when you stop masturbating?" "It disappears completely. And I look like a normal girl." she said. "How long does it take?" "After hentai porn gif, only two minutes." "Can you let it disappear now?" "Hmmm..." she hesitated. "It may take a while." she added. "Why?" Ben asked. "Well, your hand feels extraordinarily good, brother." Ben startled and suddenly recalled that he had been slowly caressing her cock as they talked. He pulled his hand back. "Please don't..." she whispered. "I liked it there..." Ben complied, a small part of his mind knowing that he was far gone now. And that he was hard as a fucking rock in his boxers. He grabbed his sister's cock more firmly, feeling its entire length coated with what was probably her own pussy juices. Or maybe it was precum? When his hand reached the tip, he indeed felt a copious amount of precum dribbling slowly from her cock. When he slipped his hand back down, Lily arched her back and groaned in pleasure. "Can I see..." Ben started to ask. "Of course..." Lily said, reaching to turn the lamp on anime taboo xxx. Lily then pulled the blanket away and Ben marvelled at the sight in front of him. And even though he had touched it, seeing such a huge cock jutting from his sister's pussy shook him to the core. It shocked him rationally. He had been living his life according to rationality and science, was learning about the human body at college... But this... This was impossible Viper GTS Episode 1 – hentai rape free porn. Impossible yet right there. It also shocked him emotionally. Lily was lying in front of him hentai futanari comic, naked except for her tank top over her breasts, covered with sweat, writhing in pleasure as he caressed her. Her own hand was playing with her pussy as he kept caressing her cock. That was the stuff of his fantasies! And now this huge cock? It was too much! Ben turned on the bed to be more comfortable, and he heard Lily gasp. Looking up, he saw her looking at his erection. "Are you hard, brother?" she asked again. "Yes... I'm sorry, but yes. I don't think I've ever been so excited in my entire life." he said. "Don't be sorry... I certainly don't mind. In fact," she said with a smile "I'm rather pleased that you are. Don't stop what you're doing..." she finished censored hentai gifs, almost purring with pleasure. As Ben kept masturbating his sister, he marvelled at the sight of this still-growing cock. It must now be close to ten inches long and proportionally thick. Shit it was huge! After a particularly long moan, Lily squirmed on her bed and suddenly reached up to grab her tank top. When she pulled it up and over her head, undressing completely, Ben gasped again. Lily's small yet sexy breasts were very clearly much bigger now. If normally she wore B cup bras, she was now at least a D cup, with huge aureolas and nipples on top. When she squeezed her own breasts with her hands, Lily groaned and cried out in pleasure. "Don't stop Ben... go faster, yes, like tentacles faster again... Oh shit!" she cried out before her entire body arched upwards. Ben's eye widened again as he saw a huge load of white cum spraying from her cock, shooting upwards before falling back down on her stomach. Even during his most intense orgasms, even if he pooled all of his jets of sperm into one blob, it would never amount to this much sperm. Then another jet appeared, and another. After looking at the pool of sperm that was already flowing down her sides, Ben looked up at Lily's face. And now he could see, without a doubt, that her eyes were glowing. And so were her nipples. Looking more closely, he also saw faint lightening-like tendrils of blue-green light emanating from her nipples all around on her skin. Like veins of light, the tendrils danced a few seconds before disappearing, only to be replaced by new ones. And her cock kept spewing sperm. After the first three big streams, there were maybe four or five other smaller ones. By the time she was done, she was pretty much covered in sperm. She came back down from her intense orgasm and looked at him, all the fear gone from her eyes. She was grinning and stretching like a cat, her long groan sounding almost like a cat purring. Lily pressed a finger in the pool of sperm on her belly and brought it to her lips. Then another and another. Soon she was drinking a lot of her own sperm and Ben was looking at her, his mouth agape. "Why don't you try shibari gifs some?" she asked. Before he could stop her, she had placed her cum-covered finger inside his mouth and he tasted and drank her sperm. While it had the same consistency as his own regular sperm, it tasted quite different. It was actually good, very sweet. Lily's eye were still glowing slightly. As he felt the cum flowing down to his belly, he felt a pulsating warmth spread in his chest. Irritated by his constricted cock, he slipped his boxers off, murmuring "Fuck it..." in the process. Lily looked at his cock and purred in pleasure. Ben was still holding her cock and soon he felt it get smaller and smaller until, a minute later, it fully disappeared. Lily, looking at him with a hand on his thigh, said "So? What do you think?" Staring at her nude body, her big breasts compared to her frame and her flawlessly feminine pussy in glorious display, Ben said "I think you're the most beautiful and sexiest girl on the planet." Lily giggled and said "Thanks. But what do you think about my manga gifs?" "Oh... Well, I think that's obvious!" he said, glancing at his own cock. "That's for me?" she asked, grinning. "Yeah. If you want it. But first, let me check your pussy." "With pleasure..." she said, spreading her legs wide opened. Ben knelt between her legs and brought his face right next to it. It was perfectly normal. Wonderfully beautiful, but normal. "Can I check inside?" he asked. gakuen chijoku no zushiki 2 anime sex blog nude anime teen "Right now, brother, you can do whatever you want with me." And so he slipped his finger inside her and curled it upwards. Lily gasped and moaned, then giggled. "If you keep doing that, the cock will come back..." "Really? So fast?" "Oh yes. I have a male's cock, but I can climax as often as a woman!" she said, giggling. Ben moved up and shuffled his knees, walking on all fours above her. When Lily lifted her legs and wrapped them around his waist, he looked up and mumbled "Oh, I wasn't about to... I wasn't trying to double penetration hentai gif" "I know, she replied. That's why I grabbed you before you could move away." They stared at each other for a long while, and Lily said "Why don't you fuck me? We both know you want to..." And so Ben lowered himself and found his sister's pussy. He groaned as he penetrated her, her pussy feeling like a normal pussy. The best pussy ever, the pussy he'd been dreaming about for a long time, but still a regular female pussy. He buried his face into her neck and began fucking her. Soon though she grabbed his head and pulled him in for a kiss. When she started to french kiss him, he moaned, but when she pushed a tongue that was too long inside his hentai torture gif, he was surprised. Lily's tongue was way longer than any other tongue he had experienced before. It wasn't important though. Not at all. He was fucking his sister, overwhelmed by pleasure and hearing her moaning. Soon though, he felt her cock beginning to grow again, sliding between their two bodies. The precum-lubricated cock slid between them and it clearly enhanced the pleasure Lily was feeling. Suddenly, breaking the kiss, she said "Wanna suck my cock, brother?" "Gods yes!" he heard anime hentai gif Ben pulled out of his sister's pussy and knelt on the bed. Graceful as ever, Lily stood up and pushed her cock into his face. It was now about six inches long and Ben grabbed it at the base and opened his mouth. Surprised by the girth and the amount of space it filled in his mouth, Ben experienced his first cock. Looking up into his sister's eyes, he saw that they were glowing again, and he abandoned all hope of understanding what was happening. Magic. It was fucking magic. He did his best to please his sister and it was working. Soon her cock was fully grown and Ben couldn't even take half of it in his mouth. Yet Lily was moaning like a succubus and he knew she was on the verge of cumming. When she froze and controlled a shout that would have wakened the entire neighbourhood, Ben braced himself for her cum. Surely she couldn't cum as much as she had earlier? Oh she could! Fuck! In an instant, his entire mouth was filled with the sweet stuff. After he swallowed his first load, enjoying the sweet taste, she came again and he felt some of her sperm overflowing down his chin. Lily pushed her cock deeper and Ben almost choked. Yet she was cumming again and pushing harder and harder. Suddenly, without warning, his throat relaxed and he felt Lily's entire cock slipping down his throat. He briefly fought his gagging reflex, but it passed. When his nose buried itself against her taut belly, Ben was shocked. Lily pulled out one time, letting him breathe, before plunging back. "You need to drink it all, brother... masturbation hentai gifs" she groaned as what felt like litres of her sperm filled his belly. She fucked his face a few times and Ben's mind was blown by the sensations of this huge cock opening his throat. He had seen this in porn, with tiny blonde girls throating huge black cocks, but this was insane. And insanely pleasurable! Ben could feel his cock twitching in pleasure. Lily eventually stopped fucking his throat, pulled out and let him breathe normally. Ben fell on all fours, convinced that he was going to vomit it all. He had swallowed so much! But he didn't. He actually felt very good, a warm, radiant sensation deep inside his belly that was spreading all throughout his body. His head sprung upwards when he felt Lily's huge dick land wetly on his ass. And lower back. "Ready for this, brother?" Lily asked behind him. "Wait, it can't possibly... There's no way you're going to be able to fit all of—" "You worry too much, brother." Lily said, obviously drunk on lust. "Besides, you're already starting to change..." Before he could begin to wonder about what she had meant, Ben felt her put the tip of her cock against his asshole. Obviously he'd never had a cock up his ass before, nor had he ever played with his fingers or toys back there. His medical student mind knew that his sister's monster cock would tear him apart. Then again, a sister wasn't supposed to have a twelve inch cock. He cried out in pain as he felt the entire head of her cock slip through his sphincter. But there was much less pain than he had anticipated. Shit! His asshole was stretched beyond measure, her cock probably as thick as his wrist. But not that much pain. In fact, Ben had to admit that it was starting to feel really nice. As she held on to his hips, Lily pushed her cock inside him. She'd go two inches in, one inch back, two inches in... A minute later, with roughly half of her cock inside him, Lily was already fucking him harder and harder. With every other penetration, Lily slipped hentai gifs. Ben imagined that her precum kept his asshole lubricated, but he couldn't believe that it was happening, nor that it was making him feel so good! He was pretty sure the last inches would be the most painful, his bowels not expecting such a monster. Yet he gasped in pleasure as he felt her thighs on his ass and soon his entire body was rocking violently with every thrust. Lily was pounding into him savagely, fucking his anus with her monster cock. Turning his head to look at her, Ben was fascinated by what he saw. While she was still definitely his sister, Lily was now clearly a magical creature. Her eyes were glowing so much that the entire room was blue-green. As she licked her lips with her long tongue, they were starting to glow faintly as well. Her dark red hair was now longer, brighter and seemed to be almost floating around her. Her breasts had grown tremendously, swinging heavily with her movements. Her nipples were nearly as bright as her eyes and the tendrils of light emanating from them now covered most of her torso. Lower, above his own ass and her cock, Ben could see that Lily's bush was now glowing as well. Finally, he could see her fingernails getting longer and, of course, also glowing with that eerie light demons gifs. Still on all fours, being sodomized for the first time, Ben still couldn't wrap his head around how good he was feeling. He watched her pulling away so damned far before ramming all that cock into him again. Yet no pain, only pleasure now. So much fucking pleasure! He'd had great sexual experiences in the past, but this... This was on another level! He had never know that an asshole could be so— But his train of thought stopped suddenly, completely derailed by a new sensation. An utterly new sensation. ahegao at first but quickly becoming unmistakable, Ben felt his pecs beginning to move with each of his sister's thrusts. He knew he wasn't built like a body builder, that his pecs weren't super taut, but the movement he was feeling was just too much. When he reached with one hand to feel his pecs, he got yet another shock: he wasn't touching pecs, but small breasts. As Lily kept hammering into him, he felt his new breasts growing and growing until they were slapping against each other in sync with Lily. Dropping his face on the mattress, he grabbed his new breasts with both hands and cried out in pleasure. He had always liked to play with large breasts, but squeezing his own overwhelmed him. "Fucking hell!" cried Lily behind him as she climaxed again. Ben felt her sperm filling his bowels, then felt its magic radiating all over his body. At once his breasts, which might have been C cups, magically grew into much larger E or even F cups. Lily pounded him hard all through her climax. Ben wasn't feeling any pain now, just overwhelming pleasure. When Lily pulled out, Ben felt his asshole gaping, letting some of her sperm leak out. When he turned around and looked at Lily, he still recognized his sister despite the transformation. She was smiling naughtily, but even after everything that had happened, her head was slightly lowered as if she was shy. Ben knelt in front of her and hugged her hard. At the same time he uncensored hentai gif their cocks intertwine against one another. Without looking he could feel that his average sized cock was now much longer and that both cocks were now trapped between their four large breasts. He leaned forward and kissed Lily on the lips, driven by a hunger and passion he had rarely felt before. Sliding his hentai handjob gifs down her back, he grabbed her ass and cried out in pleasure and he enjoyed her firm flesh. He was only barely surprised when he felt a thin but strong tail growing from the top of her crack. Following its length with his fingers, her reached the end and felt a thicker puff of very fine and very soft hairs. Ben only laughed, way past the point where he had given up on explaining what was happening. He pulled his sister against him and let himself fall on the bed. She straddled him and rose up until she could guide his cock into her pussy. Ben laughed again as he felt his ten inch cock penetrating her pussy with ease. When Lily started to ride him, Ben was hypnotized by her huge cock bouncing with her, slapping his belly with each bounce. Lily reached for his breasts and fondled them, a large smile on her lips. "Hold your breasts like this..." she suddenly said. When he did, Ben saw her pushing her gigantic cock down between them. So even as she was rocking his cock, she was fucking his breasts. His mind overloaded by all he was seeing and feeling, Ben abandoned himself to the pleasure. Feeling her cock fucking his breasts was an experience he hadn't fantasized about because it was so crazy. But he was living it right now, feeling his pleasure growing and growing. As much as he liked this position, he had another idea. He pushed his sister off of him and turned around on the bed, his head off the edge, thrown backwards. "Fuck my throat again!" he said. Lily grinned, then knelt right in front of him on the floor, her cock at the perfect height. Knowing it was physically impossible for him to take that monster cock into his throat, Ben nonetheless opened his mouth and shivered when he tasted his sister's anime big boobs gifs again. Much smoother than the first time, Ben experienced a second deepthroat as Lily buried herself to the hilt. He felt his insides being reorganized again as twelve inches of magical cock speared through him. And suddenly, things got even more intense. He felt his sister taking his own huge cock into her mouth and, after a second of repositioning, she took all of his length into her throat as well. Like a well oiled machine, Lily and Ben began deepthroating each other, taking their respective cocks as deep as was possible, giving each other more uncensored rape hentai gifs than either had thought possible before. Ben felt her breasts on his as they moved, and soon felt some magical milk coming out of them, making them slick against each other. Reaching up to grab her ass, Ben pulled Lily as hard as he could into him, feeling her pussy pressed against his nose. And that's how they both came, filling each other with more sperm than was physically possible. Luckily for them neither of them could scream, but they were both filled with a mind altering wave of pleasure that lasted for long minutes. Eventually, Lily pulled back and released his cock before pulling out of Ben's mouth. Ben moved higher on the bed, resting his head on the pillow. He opened his arms and felt deep, powerful love fill him as Lily lay against him, her face buried into his neck. He could see his own breasts pressed against hers, see her glowing skin shine light in the room and her long, thin tail whipping around behind her. It was utter insanity, but he was the happiest man in the world. The following morning, Ben woke up on his sofa bed, all stiff and aching. Reflexively he reached for his breasts, but found nothing but his ordinary pecs. Lower, he felt for his cock and found it, also, no longer than usual. Standing up, he looked at himself and couldn't find anything different than usual. His throat and asshole weren't sore at all. "Shit! Was this all a fucking dream?" he asked himself. He looked around for any trace of what had happened, but didn't find any. Of course, most of it had happened in Lily's room. He got out of his room and headed for the kitchen. He was all alone, everybody was still sleeping. The utter normality of this morning was a deep shock for Ben as he ate his cereal in silence. "A dream?" he thought. Fuck! "Of course it was a dream!" he told himself. "Magic isn't real, you big dummy!" But it had felt so fucking real! "Real?" he laughed at himself. "How can a girl with a twelve inch cock and a guy growing F cup breasts feel real?" He shook his head, both relieved and slightly disheartened. After finishing his bowl he remained sitting there, trying to understand what could have triggered such a power and crazy dream! Had Lily even come to his room last night? That first time when she talked about the party? Was that even real? Suddenly he heard footsteps coming from downstairs, and Lily appeared at the top of the stairs. She was still groggy from sleep, and went to the fridge, saying "Good morning" as she walked next to him. Her small breasts looked perfectly normal under the fabric. He stared at her from behind. She was hentai gangbang still wearing a tank top, another one this time, and it barely covered her ass. Her slim and small ass, just like her breasts were. Small. Feminine. No hint of a cock. When she leaned forward and he saw her pussy peaking between her cheeks, it confirmed that there wasn't anything magical there. Well, his sister's pussy was certainly nice and it was certainly arousing him this morning, but— And then it happened. Lily turned her head to look at him. He saw her smile naughtily and suddenly her eyes glowed blue-green, coloring the entire fridge. When he saw her fine tail falling down from between her buttocks, under the tank top, then whipping around a few times, Ben smiled. It hadn't been a dream, and he knew his life was about to change for the best, for the extraordinary. For the magical.
