Teen titans: Urges of the Beast
Beast boy’s body is changing and he’s discovering urges he didn’t realize he had, as are Raven and Starfire.
Hi this is the first story I posted. I did not make this story, but a friend of mine did though that person want to stay anonymous. I help that person come up with the idea for the story and help him/her come up with various idea for this story and many others. I'm no author or artist, but I can come up with a lot of ideas that can go with a person story if I know the style of their writer well enough. That enough about me; I will let you get back to the story and I hope you enjoy it and maybe he /she will write more for you.
Teen Titans: Urges of the Beast
Beast Boy felt different. Something had changed inside of him. He always felt a connection to his animal side, but recently it had become so much stronger. He felt urges more intense than he had before, and even his body had changed. His muscles were a bit larger and he'd grown a few inches taller. More distressing though, he was almost constantly hard whenever he was near Raven or Starfire. It was quite hard to hide it too since his skin tight outfit basically outlined his uncut cock in vivid detail. It was even worse when he needed to transform since there was nothing at all to hide his arousal. Raven once caught sight of his dick when he had turned into a dog and worse than that was the fact that there was a female dog right next to him. He tried to explain that it was just his animal body reacting and not actually him, but she didn't want to hear any of it, quickly slinking away into the darkness wearing a bright red face.
What Beast Boy didn't realize, and neither did anyone else, was that he was also starting to produce a musk that was driving any female near him into a fervor. That was why the female dog had approached him, and also why Raven was watching him intently as it happened. She did a good job hiding her interest in him but was less successful when she tried to convince herself that there was nothing there. The more that she was around him, the more she couldn't help but notice his toned body, firm rear, and the well-endowed outline in his pants.
Even Starfire was effected despite her alien physiology. Like Raven, she didn't realize it at first. When she finally did she wasn't as dismissive of it as Raven was. Tamaraneans were much more open with their emotions, and it wasn't uncommon to have many lovers. Humans though seemed to shun polygamy, and she didn't want to hurt Robin's feelings. Still, as time passed she couldn't help but notice more and more that the little green man was looking more alluring. Recently she started to wonder what it might be like with someone who could change into so many interesting forms.
Robin and Cyborg couldn't fail to notice BB's near constant erections. Unsurprisingly there much teasing suggesting that he's been hitting those natural male enhancements a bit too much. Beyond that though, neither of the men seemed to notice his musk or the two women's growing infatuation.
Things went on like this for several weeks. Beast Boy grew another inch, his hair was a little longer, and his chest actually started to look toned and defined. It wasn't super apparent though, as BB had started to wear baggy clothing over his purple and black outfit. It did an okay job hiding his continual changing body. Like his body, his musk too grew stronger as did its effects on the women. Neither Starfire nor Raven could get their minds off the green stud. The feelings Starfire had for Robin were dwarfed by her lust for the now taller changeling, and to Raven's horror, she too kept imagining herself with him in multiple positions and forms making it almost impossible for her to keep control of her powers.
When it seemed that there was almost no way Raven could stand another minute near the irresistible green man relief came, or so she thought. A call came in from the Titans East needing some help dealing with storm relief or something. She really didn't catch it all, and frankly didn't care too much what it was so long as it got her some time to clear her head. She was shocked when she learned that Robin thought that he and Cyborg could do the job alone. She tried to convince him that she could help, but he wouldn't budge. He was worried about something happening in the city if too many of them were away. Just a few hours later the two men took off, leaving Raven, Starfire, and Beast Boy all alone in Titan's Tower.
The rest of the day was strange. Raven locked herself in her room, which wasn't all that unusual, but Beast Boy noticed that she didn't even come out to get something to eat. Starfire seemed to spend the whole day avoiding him as well. If she entered the room with him, she'd immediately turn around and leave after making up some kind of excuse to try and keep from hurting his feelings.
Raven tried her best to meditate, but it was completely impossible. Every time she closed her eyes she just kept picturing Beast Boy in various levels of undress, then she imagined him stroking his long shaft and beckoning her over to help him. She tried to imagine something else, but then it only got worse with him taking various animal forms that she'd seen him take, only of course with his meaty shaft on full display. Without even realizing it she had slowly lowered her right hand down to her crotch and had started to gently rub her fingers up and down her wet slit. Soon enough she realized what she was doing, but she couldn't stop. She was too pent up and needed some relief. Maybe if she did this, she'd finally be able to get her mind off him.
The pale skinned woman pulled her leotard aside and slid two fingers into her drenched pussy. She let out a soft gasp as she felt her digits slide inside her warm depths. She'd only done this a couple of times. Once experimentally and a few times after she caught a glimpse of Aqualad skinny dipping. This time was different though. She didn't feel embarrassed or intimidated. This time she felt like she wanted more. She wasted no time in picking up her speed. Her free hand went up to her pert breast and began to fondle it and occasionally rubbing her thumb against her nipple through the thin, tight cloth. When that didn't feel like enough she added in a third finger, then a minute later a fourth. She couldn't believe how much she has pushing inside of herself. It was more than she'd ever tried in the past. She moaned as her fingers moved rapidly but even that didn't seem like enough so she reached down with her second hand and started to tease her sensitive clit. She let out a squeal of pleasure as she felt a jolt of electricity shoot through her. She was getting so close.
"Damn it!" Raven yelled pulling her fingers out of her needy cunt, dripping her juices onto her bed as she sat their panting. "Why can't I just cum. No matter how hard I try, I just can't!" She looked over to one of the walls. Several rooms over was Beast Boys bedroom. She knew all too well how close he was. She could faintly smell his scent now, he must be back in it. She glanced at the clock and couldn't believe how late it was. How long had she been fanaticizing about BB and trying to masturbate? She returned to looking at the wall and bit her lower lip. "Maybe if I..."
A few minutes later Raven silently phased through the wall and hovered above the ground in the shadows. She looked over the messy room, though messy was hardly sufficient to describe it. Under any normal circumstances, she would never set foot in the room. It was so piled up with junk, dirty cloths, and what she considered trash that she wouldn't be surprised if she caught some sort of disease if she spent too long in there. Today though, she barely even cared that she was in such a disgusting environment. All she cared about was the green stud lying under the sheets, with his long thick cock raising them up. If she didn't know any better she would have thought that he planned this. Of course, that would imply that he was smart enough to think that far ahead and she doubted that. She floated over to the bed and hovered above him, listening to his soft snoring that sounded a little weird. At first, she thought maybe he was faking it, but it quickly became clear that wasn't the case.
The pale woman reached out and softly spoke her magic words, "Azarath Metrion Zinthos." A dull black glow formed around Beast Boy's form then dissipated. Satisfied that her spell had worked and that he would not wake up she reached out her hand and telekinetically removed the sheet from the green stud as she licked her lips with anticipation. "Well shit." She muttered to herself as her lustful glee turned to disappointment. Instead of seeing the muscular man she had been imagining, there was a large green wolf lying on his back with a huge cock lying across his stomach. She sat down on the bed next to the wolf and sighed. It looked like she wouldn't be getting any relief tonight. Was she really going to have to approach him and actually try to convince him to have sex with her? That just seemed so humiliating, mainly because she just knew he wouldn't be able to keep his mouth shut about it.
Raven turned her head back to look at Beast Boy again, and couldn't keep her eyes from being drawn to his strange looking penis. It wasn't like the outline she'd seen in his pants or any of the pictures she'd seen online. It was way more pointed at the tip, and a deep green instead of his skin colored. Plus at the very back there was to large bulges that at first she thought might have been his balls, but she quickly realized that those were even further back. "I can't do it with a dog... Can I?" She asked herself. As if to answer, she was already reaching out towards his penis with one hand. She hesitated for a second, then gently ran her tender fingers down its length. She guessed it had to be at least a foot long and thicker than her wrist, and that wasn't even counting the increased girth at its base. "This is a bad idea, something this big is way too much for me." She wrapped her fingers around the middle of his cock, unable to quite make her fingers touch. "It's so thick and long. Way too much for me to handle, but maybe if I just took the tip. That wouldn't be too bad, and it'd probably be enough to get me off." She reasoned to herself.
The ashen skinned woman crawled onto the bed and straddled the wolf. She hesitated a moment, then removed her cape and unzipped her leotard so that she was naked above the green beast. She could feel the cool air on her breasts, making her nipples hard but she didn't feel cold. Her cheeks were red with embarrassment and she felt hot as her blood raced through her veins. His musk filled her nose, making her even wetter than she had been when she first saw his naked form. She reached down and took hold of his heavy meat, raising it up so that its tip was at her needy cunt. She bit her lip to fight off a moan as she allowed herself to sink a couple of inches down onto him. His pointed rod spread her folds easily, slipping into her pussy like he was made for it. His strange penis head felt wonderful, and she just sat there for a minute enjoying the feeling of his warm dick spreading her. Then she began a slow methodical rhythm of pushing herself up and down his length, being careful to only take the first two or three inches at most. Even that spread her as much if not more than her fingers had. It was heaven to the half demon woman. She didn't care that he wasn't human right now, she didn't care that he was asleep, all that mattered was that she was finally going to get some relief.
Raven tried to keep her slow rhythm but found it difficult to stop herself from going fast or trying to take him deeper inside of her. He just felt so good, way better than any of her previous times using her fingers. After just two minutes she gave up trying to maintain control. The slow pace gave way to rapid random movements. She didn't care anymore about him being too big for her to handle. She let out a long lust filled moan as she leaned down putting her hands on Beast Boy's furry chest. Raven lifted her round ass up so that only the very tip was still in her. "Let's see what you can do doggy boy." She pushed herself backwards taking half his cock into her needy vagina. Raven let out a stifled scream as she felt him rip through her hymen, but didn't slow down. She pushed herself up, then drove herself down again taking a little more as a trickle of blood ran down his shaft.
"Fuck me, I should have done this sooner," Raven exclaimed as she continued to force more and more of the wolf cock inside. After a dozen or so thrusts she had two thirds of the dick in her and she felt it pressing up against something. There was a strange pressure inside her that she wasn't sure if she loved or hated. Either way, she wasn't going to admit defeat quite yet. "Is that my cervix you're pressed up against? You're quite the monster, aren't you Beast Boy. It's a good thing you're asleep right now otherwise you'd make some kind of stupid joke and ruin the mood. I'd hate for that to happen since I intend to keep going. I never even considered what it would be like to feel someone inside my womb until right now." The pale woman picked herself up off him completely, took a deep breath and grit her teeth in anticipation of what was to come. She slammed herself down taking the rest of his shaft, save only for the engorged knot at its base. She let out a silent scream as her cervix was spread wide and her womb stretched far enough that when she looked down she saw her belly bulging. "Look at what you've done Beast Boy, you've ruined me." She said as she repeatedly took his length over and over again.
Despite being unconscious Beast Boy's body was reacting to everything she was doing to it and integrating it into a very erotic dream. He was panting and yipping with glee from the constant growing pleasure. Even his legs were twitching every now and then as his tail wagged profusely. Raven increased her speed and she began bouncing up and down his shaft he even began to sporadically hump.
This went on for a good 15 minutes before Raven was completely at her limit. She could tell that Beast Boy was as well, she didn't know why, but she felt like there was still something she needed to do. If she could just figure out what that was, she'd finally get relief. After a few more times up and down his rod, she figured out what it was, that bulbous thing at the bottom of his cock. She once again reached the bottom, feeling his knot pressing against her soaked cunt. She was already stretched as wide as she thought possible, but that no longer mattered. She had decided that she was going to take all of him. He seemed to have the same idea, or at least his body did. She could feel him trying to thrust up into her. If she just used a little more force the next time she went down on him they'd both get what they want.
With one final effort, the Ashen girl forced herself down onto the green wolf. She let out a strained grunt as she ground her teeth together. The pain of being stretched so wide was excruciating, but it only lasted a few seconds before the relief and pleasure of being so completely filled permeated her body. What sounded like a small bark came from Beast Boy followed by howl mixed with a whimper as a warmth began to fill her. She instantly knew it was his seed filling her over stretched womb. He was unleashing it into her like a torrent. In an instant, he had already cum more than most men could, and that was only his first shots. His cock pulsated and jumped with each shot of his seed. Her whole body shook with ecstasy as she was hit by the most powerful orgasm of her life. Nothing she'd experienced before had prepared her for this. Her belly continued to swell, at first making her look a bit bloated, then slightly pregnant, and finally looking like she was almost ready to give birth. Over a gallon of cum sloshed around inside her overstretched womb. The feeling was so intense she nearly passed out. She did completely loose her muscle control, collapsing forward onto the furry green chest of the wolf.
Raven didn't know how long she laid there catching her breath. Her chest heaved up and down against his warm fur. She enjoyed the feeling, content to finally cum after weeks of needy build up. She didn't even think how strange it was that her first time with a man, was actually a wolf. She wanted to fall asleep but knew she couldn't. There was no way she was going to get caught in here with him, especially like this. She finally forced herself to pull off of him. Enough time had passed that his knot had gone down a little, but there was still a wet pop when he finally became dislodged. Creamy white liquid gushed out her gapping cunt splattering all over his crotch, legs, and belly. It felt almost as good coming out as it did going in that she nearly orgasmed again. In fact, the only thing that kept her from doing so was hearing him starting to wake up. With no time to think, she acted on instinct. Her powers activated and she phased through Beast Boy, his bed, and the floor before he fully awoke.
"Ughhhh" Beast Boy yawned as he sat up. "What time is it?" He looked over at the clock seeing it was 2:00 AM, then he looked down at himself. Even in the dark, it was clear to see what he'd done. "Oh shit, oh shit, oh shit!" He swore at himself as he jumped out of bed. Thick rivets of jizz were slowly dripping down his belly and thighs. It was a huge slimy mess. "I need to take a shower before anyone sees me like this."
The green man poked his head out his room, looking from side to side to make sure the dark hallway was empty. It was completely devoid of life, just as he expected given the late or rather early hour. Satisfied that it was clear he began to tiptoe his way towards the bathroom. He slowly slid the door, praying it wouldn't squeak. He let out a sigh of relief when he was inside. He flicked on the light switch. He made his way to the shower and twisted the knob, readying himself for the initial burst of cold water. Suddenly his hair stood up on the back of his neck.
A knock came at the door. "Friend Beast Boy, are you trying to use the bathroom. I feel that I must apologize. When I was training earlier I somehow damaged the water main." Starfire said outside the door with a smirk that more would have looked at home on her evil sister.
"Oh, that's no big deal. I, uh, I'll figure something out." Beast Boy said stuttered out as his heart started to beat faster.
The alien girl put her hand on the door and began to forcibly slide it aside. "I feel as though I must make amends."
"No! That's really not necessary" Beast Boy yelled as his face turned bright red and he grabbed the shower curtain to cover his naked body.
Starfire entered the small room grinning and walked over to the blushing man. She looked down at him and licked her lips as she pulled away the curtain. "Nonsense, I made the mistake so I should fix it." She let out a small gasp when she saw just how messy he was. She had overheard the very last part of his and raven's encounter. It had sounded quite enjoyable, so much so that she couldn't resist trying him out. She had expected him to be a bit sloppy, but he was positively drenched. She ran her finger down his chest to his belly so she could get a dollop of his seed. He shivered as her soft digit moved downward then gulped in shock as she moved it her mouth to lick it clean. "Mmm, wonderful. You taste even better than mustard, it's a good thing the water broke. I'd be a shame to waste this with water."
"Starfire, this... this isn't right," Beast Boy said as the orange skinned girl kneeled down and licked at his belly.
The alien gulped down a mouthful of his spunk then giggled. "Whatever do you mean? Is this not helping you get clean? Perhaps I should try harder." Before he could try to explain what he meant, she leaned her head down and engulfed the head of his hard cock with a loud slurp.
"Oh god, it's so warm." Beast Boy said with a moan. Starfire stuck out her long tongue and began to slather the bottom of his dick as precum dribbled into her mouth. "This is amazing... but you need to stop. Robin will never forgive me if he finds out about this."
The Tamaranean girl pulled off herself off his dick. "I do not believe that you really mean that. You could have stopped me any time you want by transforming into some powerful animal. Do you know what I think?"
Beast Boy shook his head and said "no." She licked across his toned stomach gathering more of his tasty essence.
"I think you're fighting your animal side. If you transformed it wouldn't be to stop me, it'd be for take control and use me to your hearts content." Starfire took hold of BB's thick dick and slowly began to stroke it as she used her tongue to lick his helmeted tip and under his foreskin. "You know what's even more interesting? Tameraneans physiology is much hardier than a normal human, so it'd take a real stud of a man to make one of us cum. I wonder if you have it in you."
Starfire's goading was too much for the horny man. Beast Boy let out animalistic growl, grabbing her red hair and pulling her mouth into his crotch. She squealed with glee for a brief moment before gagging as 10 inches of his uncut cock were rammed into her throat. "Is this what you wanted Star, or was it more like this." He pulled back his hips then rammed forward again, slapping her chin with his heavy balls. He gave several short thrusts, then pulled out completely. Several strands of saliva went from her lips to his rod. "You don't need air, right?"
Starfire nodded her head. "For all practical purposes, I do not require oxygen."
Beast Boy gave her a toothy grin. "Good, that means I don't need to waste time pulling out just so you won't pass out." A moment later the green man was pounding his meat in and out of her mouth. Sometimes he pulled out a few inches before thrusting back in, other times her pulled out almost all the way. No matter what though, the never completely removed his dick from her maw. Starfire's mouth was like a waterfall she was drooling so much. The mix of his musk, taste of his shaft, and his constantly dribbling precum was driving her mad with lust. As the minutes ticked by, and his stamina seemed to go on forever, Starfire couldn't keep from touching herself. One of her hand snaked down into her skirt, shoving three fingers into her tight pussy while her other hand went under her shirt to fondle her breast.
After another couple of minutes, BB paused with himself balls deep in the orange girl's mouth. Star thought for a moment that he was at his limit. Then she felt his cock grow larger, stretching her throat wide and reach down to her stomach. She cast her eyes upward and saw that the green man and turned into a large Gorilla. "Hope you weren't joking about liking it rough" Came a much gruffer sounding voice out of the Gorilla. It was surprised Starfire a bit since he never managed to speak as an animal before, but she didn't have time to think about it. The strong animal's large hands gripped her head and began to move her back and forth along his oversized cock while he also used his strong legs to thrust himself into her face. Repeatedld she was mashed into his crotch. A pair of heavy baseball sized tentacles slapped her chin while her nose was slammed against his hard belly. Her jaw was practically dislocated he was stretching her so wide and her eyes watered at the feeling. Yet, despite all that, she was happier than she had ever been. All thoughts of Robin had left her mind, all that mattered was the dark green dick that she was gagging on.
As a Gorilla, BB didn't last much longer. After just a few minutes he came with a roar. He pulled himself out of her mouth and erupted onto her face. Her bright red hair and orange skin was turned white as a gallon of steaming hot spunk splashed against her. The smell and feel of it was amazing, and she eagerly caught what she could in her mouth to drink down. It took almost a full minute for him to completely stop ejaculating. BB stumbled backwards a couple steps and turned back into his human form. "God damn, that was good."
Starfire drank down the cum that she caught in her cupped hands before responding. "Yes, that was most enjoyable. I hope that is not all you were intending to do."
"Not a chance. I'm going to fuck you so hard you won't even be able to walk right, but first I need to take a piss." The green man said strolling over to the urinal. Suddenly he felt Starfire's strong hand grip his wrist and pull him back towards her.
"Recall that the water is not working, and it is distasteful to not flush the toilet. Perhaps it would be better if you used an alternative." Star said grabbing his semi erect cock. She stuck her tongue under the foreskin and licked around his tip before placing his dick once again in her mouth. "I am eager to see how your different bodily fluids compare to one another."
"You're a real pervert Star." Beast Boy said as he relaxed and allowed his bladder to release its contents. The salty acrid fluid splashed across her tongue and quickly began to fill her mouth. She eagerly gulped it down with as much of a smile as she could muster given the size of the meat straw she was sucking on. BB couldn't believe that she didn't suddenly pull away and start spitting it out. Of course, she drank Mustard like it was soda so it wasn't entirely unexpected that she seemed to actually like it. After about thirty seconds he was done. She gave his cock a couple last licks before she let him go. "Delicious, almost as good as your Gorilla semen. I wonder if each of your different forms produces its own unique tastes."
"I guess we'll just have to try a few to find out." The green man said turning back into a gorilla and pulling the orange woman towards him. He turned her around and grabbed hold of her panties and ripped them out with a single motion. A second later he shoved two of his large fingers into her soaking pussy making Starfire moan. "You've got quite the tight cunt. I can feel you squeezing my fingers so tightly. I bet you'd be like a vice around my cock. In fact, there's only one thing I can think of that might be even tighter." The Gorilla shoved his thumb into the woman's anus.
Starfire's eyes went wide and glowed green. "No Beast Boy that is the wrong hole!"
The Gorilla smirked. "Why do you say that it seems quite warm and even tighter than your pussy? I bet it'd feel wonderful stretched out around my cock." He wiggled this thumb a bit, making the Tameranean gasp.
"You do not understand Beast Boy, it is not proper to have sex this way." Starfire blushed bright red and bit her lip as he pulled his fingers out of her and then slid the two digits from her cunt back into her ass. "Oh my god! This feeling is..."
"I think the word you're looking for is, 'wonderful'." The green animal said adding a third digit to her overstretched ass. "If it is, then why is this so wrong?"
"On my world, only the lowest prostitute would have sex like this. It would be unthinkable for a person of stature to partake in such an activity." The orange girl let out a moan as he pulled out his fingers, leaving her feeling empty. "Yet, I cannot deny that it feels pleasurable."
Beast Boy picked the tall, thin woman up turning her around and moving both of them over in front of the mirror. "So Princess Starfire, should we keep this nice and proper?" He asked as he rubbed his wide cock head against her dripping cunt. Then he switched to probing her anus with his tip. "Or are you a dirty little whore who wants to get their ass destroyed by the big bad Beast Boy?"
Starfire wiggled her rear against the Gorilla's wide tip. "I need to know what it's like. Make me a dirty Grimplok Beast Boy."
Beast Boy hesitated a moment then grinned. "I'm going to assume that means anal." Without any mercy, 14 inches of Gorilla cock slammed balls deep into her rear. Starfire let out a scream of pain and pleasure. Her ass was stretched wider than she had ever imagined possible and her belly budged out from his overly long cock. To her time seemed to slow. She could feel his rock hard cock throbbing inside of her, and when he even slightly moved pleasure shot through her. Her scream began to peter out as the pain subsided. She became light headed as pleasure flooded her body. She gasped as she shook with a powerful orgasm. Her pussy tried to clamp down on the cock giving her pleasure, only there was nothing there. Her rear reacted the same way, constricting around his dick, trying to pull it in even deeper.
"You really are a slut, aren't you Star. You came just from me putting it in. Imagine what will happen when I let lose." Beast Boy put his large hand around her throat, tightening his grip and pulled her back so that she was flat against him. His other hand tore off her top and began to fondle her pert breasts with his strong hands. He gave her ear a little lick, making her shiver. "I hope your mind is as strong as your body, or you might just lose it."
Starfire gave a small smile, still out of it from the pleasure. "We shall find out." She said feeling an intense suction as he began to pull out. Her eyes went wide as he slammed back in and settled into a fast rhythm. The Tamaranean woman was amazed at how strong Beast Boy's primate form was. When he had used her mouth she had been impressed with what his small frame had mustered. That was nothing compared to now. He had really taken to heart her urging to not hold back. Where she a human, her hips would have surly been shattered with the amount of force he was using. Even her alien body was having some trouble. The bones in her pelvis seemed to be bending under his assault, and her ass cheeks had gone from orange to pink. Her stretched sphincter was bright red, burning from the constant friction. It should have burned unbearably, but instead, it just added to the experience.
Up and down Star's belly went, the outline of his cock becoming clearer to her with each savage thrust. The feeling of being taken like a common whore should have been revolting to her. She was a princess and a Titan. This was against all the rules, yet she loved every moment of it. "Harder Beast Boy, fuck me harder!"
Beast Boy laughed. "Just remember, you asked for this." He moved his hand from her throat to behind her head and shoved her down into the tile hard enough to fracture it. He completely removed himself from her, then slammed back in. Her whole body pushed forward, scraping along the ground. Her breasts jumped with the thrust. He pulled out and did it again. Over and over he did this, making her ass use to the feeling of being torn open by his fat dick. Under the savage assault, she quickly succumbed to another orgasm, letting out a weak scream that was muffled by the ground. He kept this up until she came a third time. "Do you still want more, or is this your limit my little... what did you call it? Gorplok?"
"Grimplok." Starfire weakly corrected. "And I assure you, despite my position, I have am nowhere near my limit." She lied as he continued to roughly use her.
"Glad to hear it. I really wanted to try a different form before I finally came. How does a horse sound?" Before she could even answer, he sheathed himself inside her rear and transformed. His cock grew longer and thicker inside of her. The sizable bulge in her belly increased traveling up her chest, between her breasts and finally stopped somewhere near her throat. It was completely disorienting, painful, and wonderful all at the same time. She couldn't see what it looked like, but she could feel with her hands how big he was. His whole cock was outlined on her body. He was so thick she wouldn't be able to get both hands half way around him, even if he wasn't inside her. Even his bulging veins were visible through her skin.
The green horse started to hump her body, not able to pull out all the way given the tight confines of the room and his massive length. Still, he managed to saw a good two feet of his cock in and out of her. His eight inch thick dick spread her ass comically wide. He had no idea how she was taking all of this, and frankly he no longer cared. He was so close, all he cared about now was cuming hard into the sexy alien. He speed up his thrusts losing his rhythm all together as pure lust took over. He lost his ability to speak, reverting back to a series of snorts and naying.
Starfire was drooling as she was rocked with orgasm after orgasm. She was stretched too much for her mind to handle. In an instant, his fat horse cock straightened out her intestines, into her stomach, and ended lodged in her throat. A second later he was only barely inside her butt. It was impossibly intense and she was addicted to it. The sensation was unlike anything that Robin could ever give her. Beast Boy was the only one that could satisfy her now, and she knew it.
After one last minute of reaming the orange girl's ass, Beast Boy came hard. He let out a long nay as his balls began to empty into her. Steaming hot horse seed filled her stomach in seconds. More and more poured in, stretching out her normally flat belly until it was round and larger than any pregnant woman. She was filled with gallons and it kept coming. There was only one exit it could take. She felt the hot liquid suddenly shoot up her throat it began to pour out her mouth, pooling on the floor. It took nearly two minutes for him to completely finish up. When he did, he was exhausted and finally satisfied. He transformed back into his normal form and pulled out. Her ass was gaping wide, though it was slowly shrinking back to normal. His seed quickly started to flow out of the opening, draining down over her cunt and onto the floor joining the already present pool. He grinned as he watched her collapse to the side, her belly still huge and her naked chest white with cum heaving up and down.
BB wasn't quite sure what to do now. Part of him felt kind of bad like he took advantage of her. However, he quickly pushed that aside instead choosing to continue to act dominant. "Look at this mess. I hope you can clean this up before tomorrow. Imagine what Raven would think if she came in here and found the bathroom looking like this." With that, he stepped around the huge sticky pool and left her lying there.
Beast Boy made his way back to his room, no longer remotely caring that he was naked or that he was dripping cum as he went. He was too tired and to smug at the moment to consider that anything bad could happen. As he approached the bed he noticed something was off. He sniffed the air, catching the smell of sex. Only it wasn't him and Starfire, it was him and Raven. The smell grew stronger as he approached the bed, and he noticed the particularly strong scent of Raven coming from some something tossed near the foot of his bed. He reached towards the source and found himself gripping a black outfit that only one person he knew would wear.
