Can’t wait to… study with you.” The hallway of the dormitory is abandoned save for a few people, two of which are Hibi and Beau, and those two are being cajoled by their fellow students. Egged on, and cheered and whistled at for putting on such an adorable display. The shorter jock black goat boy of twenty-one, same age Hibi is, has his hand against the wall and leans into the much taller pink praying mantis male, preventing him from moving away. Effectively trapping and pinning the blushing mantis in place. A trope like one would see in a manga or anime. Beau is wearing his sports vest with the school logo and jeans, his other hand in a pocket as he acts complete casual. Like sexually and socially dominating another guy a third of your size taller is normal. And Hibi is eating it all up. The beautiful and rather feminine pink mantis looks down at the cocky self-assured face of the goat guy he’d been dating for the past few weeks, blushing furiously as he holds his backpack against his chest. “Ah. S-sure, Baa. I’ll be ready.” The black goat beckons his much taller date to lean down, which Hibi does, and the two kiss passionately under loud cheering and hollering of their fellow students. Embarrassing Hibi even further, but in a good way. It makes his stomach flutter with butterflies. The black buck slaps Hibi on the ass, making the mantis squeak out in surprise, before the cocky jock waltzes away to his waiting friends. The dumb guys having high fives all around as they flock to be at the side of the coolest jock in school. Despite Beau’s height, he’s managed to snag that title for himself. And Hibi had been swooning for him ever since laying eyes on him. And Beau chose him! Him! A shy arthropod who looks more girlish than most other girls at their college. And according to many, more beautiful too. Which may be a reason why Beau isn’t getting flak for being openly gay with Hibi. Somewhat weak in the knees, Hibi unlocks his dorm room and sinks to the floor against his door as soon as he gets in. Sinking into a hot mess of a guy in love. Beau is coming over in an hour to ‘study’, and he needs to let Lilly know of the latest and greatest in their budding relationship. The twelve-year-old homunculus girl being his closest friend, despite or even because of their age difference. Lilly is a prodigy and admitted to the college at her age under special arrangements for highly gifted students. She’s also the horniest and kinkiest person Hibi knows. Hibi freshens up and texts Lilly all throughout the process, the underage girl teasing her best friend about his date with the dumbest but hottest of guys on the campus. And with Hibi teasing her back she’s just jealous she doesn’t get to enjoy the big dick on Beau. Big mistake. The texts die down immediately and Hibi starts to worry he’s said something wrong to her when Lilly suddenly responds again. She’s calling Hibi’s bluff and invokes their special secret system for it, meaning that if Hibi refuses her dare, she gets to make two others that he cannot veto. Hibi is sweating bullets, but the bulge in his pants throbs all the more for it. Damn. Why did he have to be so messed up? And why did he have to enjoy it so much too!? With shaking hands, Hibi types back that he’d accept her bluff, meaning he’d get to turn the tables onto Lilly another day. Quid pro quo, as they say. Lilly tells Hibi to dive into his personal trunk and to get ‘her’ out. Hibi immediately knows what his preteen friend is referring to and nearly drops his phone, responding with shaky fingers. “Lilly… She’s unpredictable. She could really mess up my relationship with Baa.” The response is merciless. - “Well, you can always refuse. But then I get to make you do two things you cannot veto! Choose wisely, pretty boy!” Hibi doesn’t respond and simply looks at his personal trunk in the dorm room he shares with his room mate. Luckily, he’s out for the weekend. The trunk looks completely normal, yet exudes an ominous aura now. Dammit. Lilly’s got Hibi right where she wants him. And why does that make him even harder? The beautiful pink praying mantis tentatively reaches over to the chest, no longer responding to his kinky friend’s texts, and he opens it. Changes of clothes, personal effects, and then there’s that little box with the lock. Beckoning him. Calling him. This is a bad idea. The arthropod places the box on his bed and retrieves the key from his pocket, hands shaking while he unlocks the ominous container. And then, he opens the lid. Inside is a stuffed doll, nearly perfectly resembling Lilly. The little freak dabbles in alchemy and chemistry, and thanks to her innate knowledge as a homunculus, Lilly had managed to create something that wasn’t quite alive yet had a mind of its own. Something that shares a little piece of her life force with her. Borrowed a sliver of the kinky twelve-year-old’s soul. Hibi awaits patiently, but after a few seconds of nothing happening coughs out loud: “You can stop pretending. It’s just us here.” Immediately, the big black beady eyes of the Lilly doll spring to life and squint suspiciously at the pink mantis, darting around before a small stuffed stump takes hold of the edge of the box and the doll lifts herself out. Hibi watches the mimicry of Lilly wobble up onto her two plushy feet, a large hidden mouth opening as the fabric tears, with an incredibly slick and long tongue emerging. - “Hello, gorgeous! Hibi ‘play’ with Tanya? Make Lilly feel good?” Hibi blushes and subconsciously reaches down into his lap as he kneels next to the bed, squeezing the dolphin-like protrusion from his slit underneath his pants as he’s getting excited at the prospect of what is to come. “Hey, Tanya. Yes, Hibi and Tanya will play. But! Hibi is gonna trick a friend. And Tanya needs to act like a real doll. Okay?” The innocent visage of the living doll cracks for just a moment as Tanya’s fabric mouth tears wider into a devilish grin, her long slick tongue swirling around her plush body until it teases down into the puffy padded slit that constitutes the toy’s vaginal opening. Sharing a soul connection with Lilly, Tanya is perfectly able to make the little horny gremlin feel anything she feels. And this includes the pleasure of cocks being shoved inside the plushy, which Hibi has done many times before at Lilly’s request. Today’s scenario is a little kinkier, though, as the horny twelve-year-old has requested Hibi involve the doll in his sex play with Beau later on. So that she can finally have some of that big goat dick herself. - “Tanya agrees. Fun. Sneaky! Tanya likes!” Hibi is blushing furiously, and Tanya’s beady eyes dart down to the bulge in the boy’s pants. Which elicits another grin from the unnatural magical doll. The living plush turns around and rolls onto her belly on Hibi’s bed, spreading her labia and revealing a strangely slick and warm opening for the mantis’s eyes. She knows just how to warm the kinky freak up. Not much later, there’s banging on the door. Not aggressive or malevolent, but the thuds speak of excitement and impatience. Beau is eager to spend time with his squeeze. When Hibi opens the door, the pink mantis is all flustered and blushing. The tall arthropod looks down and sees Beau looking up at him with a cocky grin, flashing some beer cans in the plastic bag he’s carrying. - “Hey, beautiful! I thought we could use some study aids. Hehe.” The goat notices Hibi’s state and smells the scent of sex when he enters the room, which makes the buck frown. - “Babe… You’re not two timing me, eh? Is there someone else?” Hibi closes the door and nearly tackles Beau to the floor, the goat jock bleating in startled surprise. The pink praying mantis digs his claws into the floor beside Beau’s head menacingly, while his lower humanoid hands tug the jock’s sports vest open wide. A deep desire and lust is reflected in Hibi’s eyes, and the mantis straddles Beau’s waist, feeling the big throbbing bulge come to life underneath. “N-no, Baa. I just… I played with myself a little before you came over. I… I couldn’t contain myself.” This strokes the black goat’s ego and his grins widely again. His handsome smug face flanked by those large curly horns and frizzy black hair are igniting the fires in Hibi’s loins. Dulling the conscience that is screaming for him to not go through with Lilly’s devilish plans. - “Oh, hehe. Couldn’t wait for this big dick to fill ya again, eh? Don’t worry, babe. It’s all yours!” Beau and Hibi lock into a fiery kiss while the both of them clumsily try to take off their clothes without breaking it, the two soon naked as the goat’s thick black humanoid cock slaps against the mantis’s cloacal slit. With just a hint of Hibi’s penis peeking out, as the arthropod tries desperately to hold back his own bodily response. Wanting Beau to fuck his cloacal slit first before his erection would make it impossible. The light pink overall body colour of Hibi’s soft carapace is quite the contrast with Beau’s furry black goat fur, and the dark brown cock pulsing from his loins. The praying mantis eagerly slides up and down the length of the caprine’s shaft, slicking up his own slit in a good bout of outercourse foreplay. Beau is bleating softly under his breath, his fingers digging into Hibi’s soft plush buttocks while teasing the large abdomen plapping down onto the floor rhythmically between his legs. - “Oh, baby! You’re the hottest girl that’s not a girl on campus! I don’t care what anyone says, your pussy beats all the others by far!” Hibi’s eye peers at the horny goat a third shorter than he is underneath him, reaching down to angle the pulsing leaking humanoid cock upward at his smooth little cloacal ‘pussy’, the soft lips rubbing a smooch down on top of the fat dark mushroom head. “You’re not disappointed I’m not fully a girl, then? Baa?” - “Hell no, baby! You’ve got a pussy and a dick! Best of both worlds, word. I’m in heaven!” That’s all Hibi needed to hear, and he firmly presses down with a long drawn-out gasp as both he and Beau moan out loud when the goat’s fat black dick sinks deeply inside the pink mantis’s blushing slit. The very tip of Hibi’s dolphin-like appendage sticks out of his opening like a clit, while the length of his dick is pressed against Beau’s going inside in the opposite direction. Both cocks firmly rubbing and squeezing against each other. Which elicits the most beautiful and deeply lewd utterances of passion from the both of them. - “Fuck, babe. Imma put some baby goats inside ya!” A shiver runs up along Hibi’s back. That’s the closest Beau has gotten to asking him to be his boyfriend as of yet! And he really, really wants him to. The two are rolling around on the floor, alternating being on top while Beau’s cock throbs away inside Hibi’s slit. The mantis’s eyes then fall on Tanya, whom is lying over the edge of his bed looking at him. Her mischievous eyes full of impatience. Urging him on to get to the plan already. The pink mantis lies underneath Beau as the goat man bleats and thrusts away inside Hibi’s slit, the arthropod’s chest heaving as he squirms in pleasure. He can’t hold back and slowly but certainly, the black goat’s thick cock is pushed out of his cloacal slit. Beau immediately plops down onto his stomach and holds Hibi’s legs wide, tonguing and licking at the effeminate boy’s slit and cock as he shallowly swallows the slender length in between slurps. Hibi is grabbing the boy’s frizzy hair and horns for dear life, trying to keep down the moaning but by now half the dormitory must know they’re fucking in here. “Ah. Ah. Baa. Baa, baby. C-can I tell you something secret? Something naughty? Please, don’t judge me.” The goat’s interest is piqued and he sits up on his knees between Hibi’s long slender legs, gently playing with the praying mantis’s cock and back entrance as he’s prepping the girly male for some more fun. - “Now you’re making me curious! Knew my baby was a little freak, hehe.” Hibi’s cheeks blush deeper and his heart pounds at being called ‘his baby’. Hopefully it wasn’t just a slip of Beau’s tongue. The pink praying mantis reaches over and grabs Tanya, the plush oddly warm to the touch as if it were a living breathing thing. Beau looks confused, then baffled when Hibi lays the toy on top of his belly and gently pries open the soft plushy labia of the doll, revealing a slick and inviting interior to his would-be boyfriend. “I’m kinda… Well. I used her before you came over. And I really want to fuck her later on knowing your cock has been inside her as well.” Hibi is red like a tomato, his eyes hiding behind his beautiful pink hair as he doesn’t dare look Beau in the face. This is it. Either the goat runs away in disgust, or he won’t mind Hibi being the kinky fuck he is. The suspense is killing the mantis, the dorm room all of the sudden as quiet as the grave. Until the arthropod feels a tentative finger explore the outer rim of Tanya’s plushy pussy, a shudder running through the living doll as she continues to play dead on top of Hibi. The mantis looks up at Beau, and sees nothing but a shit-eating grin plastered on the goat’s face while he molests what he thinks is Hibi’s plushy fleshlight. - “So you fuck plushies? Big whoop. So that’s where your girly cock went before I came over, eh? You wanna fuck her knowing my cock’s been in there? Don’t mind if I do!” Beau is talking big, but there’s a softness in his eyes. Something that reassures Hibi. Something that makes him feel like the handsome black short goat is trying to prove he’s supportive boyfriend material. The dark humanoid cock is plopped down on top of Tanya’s back, making the living plushy shudder once more and Hibi can see the flashy glint in her eyes activate. She’s enabled her soul connection with Lilly, letting the twelve-year-old homunculus girl feel whatever the living toy is feeling. Which causes Hibi’s slender cock to throb into Beau’s heavy dangly balls as the image of Lilly is projected over Tanya’s in his mind’s eye. Showing the surprise and giddiness his preteen friend is feeling when she suddenly senses a comparatively enormous cock rubbing all along her back. - “So. Your doll. Is she a single cock kinda toy, orrr…” Beau is flashing Hibi his trademark cocky jock grin, rubbing his leaky cock head all over Tanya’s back which visibly makes Lilly purr out in delight. The projected image in the arthropod’s mind’s eye doesn’t make any sound, but the visual image of his best friend, underaged as she is, being molested by his would-be boyfriend nearly causes Hibi to climax on the spot. “Ungh. N-no. There’s only one hole, though.” - “Wanna share it, babe?” “Fuck! Yeah!” The black goat grins and reaches down to finger Hibi’s slit shallowly, making the pink praying mantis as hard as possible before steering the slender dolphin-like penis inside Tanya’s plushy insides. The two lovebirds kiss passionately once more, using lots of tongue and spilling a lot of droplets of their saliva on top of the living doll while Hibi steers Beau’s cock against the opening and his own shaft. Hibi’s phone is blowing up, one notification after the other, as no doubt Lilly is messaging him about the sensations she’s feeling. About how she can feel an upscaled version of her best friend’s cock already plunged deep inside her pussy, and a very large mushroom head of her best friend’s would-be boyfriend join it at her entrance. Maybe she reconsidered and is begging Hibi to stop. Maybe she’s yelling at him to plow her silly together with Beau. Whatever the case, she’s in for it now. And Hibi’s phone is happily ignored. Beau’s thick cock head finds little resistance, as Tanya the plush is eager to receive both him and Hibi in a nice double penetration, and soon their shafts slide up snuggly inside of the plush until the goat’s balls rest against Hibi’s cloacal slit. - “Oh, fuck! She’s… wet and tight, actually. Did you put a fleshlight in there, Hibi? Fuck, I love you, man!” Hibi is seeing stars, his dick sharing a tight slick space with Beau’s cock as the goat eagerly starts to grind back and forth against him. While his humanoid arms and hands keep Tanya steady, his mantis claws lay flat on their side against Beau’s back. Drawing the handsome jock closer without hurting him. Making the virile goat’s heavy balls swing and plap forcefully against the base of Hibi’s sensitive slit. Building him towards the inevitable point of no return. The two are sharing tongue like animals, drooling all over Tanya as the mental image of Lilly is going crazy and out of her mind. Feeling two oversized monster cocks ream her underaged preteen insides like two tree trunks being shoved in there. Hibi draws back just a second, huskily whispering to Beau as his claws draw the handsome boy even closer. Holding on to his athletic back for dear life. “I love you too, Baa. I really, really love you.” Their shafts are sliding back and forth against each other. The veins in Beau’s cock are bulging, and the goat’s urethra is visibly extending in anticipation of his impending release. Both cocks, thick and blunt, and prehensile and slender, are seesawing in and out of Tanya who is grinding the spot on her plush body where a clitoris would be against Hibi’s pelvis. She’s going crazy and out of her mind just as much as Lilly is, both kinky depraved girls inwardly screaming in pleasure at being used like toys by the two boys. Hibi’s eyes hold onto Beau’s, finding nothing but lust and desire in the goat’s handsome face as the buck’s tongue lols out lecherously. “Baa. I like you. I love you. Wanna be my boyfriend?” Beau’s body stiffens as he straddles Hibi’s groin, hissing through his teeth until a full-fledged bleat emerges like a lion would roar. Hibi can feel the thick pulsing shaft expand against his, the two sharing a heartbeat through their cocks as the mantis’s eyes too roll up in their skull and both virile men release their pent-up lust. Thick creamy jets of warm goat milk spurt from Beau’s mushroom head straight into the slick inner walls of Tanya’s mysterious biology, joined by powerful watery jets constituting Hibi’s seed. Beau’s balls are warm and drawn tight against Hibi’s cloacal slit, heating the exposed base of the mantis’s slender prehensile cock as the length tenderly encircles the buck’s penis inside Tanya’s body. Constricting around it like a python would its prey, keeping Beau’s cock firmly in place as both masculine members empty a load so virile it would impregnate any female on the spot. Tanya’s tummy is bulging, filled to the brim with semen and being poked at by two impressive yet different cocks from the inside. The plush’s long tongue slips out in an unguarded moment, slathering all over Hibi’s soft chest as Tanya too shudders in an earth-shattering orgasm, just like Lilly who is who knows where. Maybe out in public, trying to save face while her body is wracked by an orgasm brought on by two ruinously large ghostly cocks resembling her best friend’s and his boyfriend to be. Fulfilling every kinky little desire the small homunculus girl could wish for. Slowly, Beau pulls out his thick shaft and plops it down onto Tanya’s back once more. Painting it white with a last spurt of manly semen before the flood turns into a drizzle of oozing man milk. Hibi’s cock too is slowly withdrawn, springing out of the living plushie’s lifelike labia before the prehensile length gently curls around the black goat’s balls. Cradling and holding them as their heartbeats remained shared, a unique sensation and a first for Beau for sure. - “You wanna go steady, babe? Hell. And here I thought we were already boyfriends.” Hibi’s eyes grow large as saucers. The blush of pleasure slowly deepening into a blush of embarrassment. “R-really?” - “Of course, babe. I ain’t a one night stand kinda guy. So, yeah. Of course we’re a couple, my kinky bug. Think of me later on when you’re using my cum for lube in your plush toy, right? And stream it to me so we can jack off together!” Tanya’s eyes flash again, breaking the connection with Lilly. Despite the toy’s mischievous nature, she knows when a private moment needs to remain private. Besides, these two will fuck at least a few more times before they’ll part ways again anyway. Hibi is stricken, at a loss for words. The living doll on his stomach forgotten as he draws Beau down into a tight hug of pure happiness, squishing Tanya flat. Not that she minds with her unique body. The mantis and goat kiss, six arms embracing the two into a cosy little cocoon as their naked bodies refuse to be still. Their male members responding to the joy and proximity of a loved one. “I’m… I’m so happy. I love you, baby.” - “Hehe. Love you too, babe. Wanna go again?” “Fuck, yes!”
