Big Dick!John x Skinny!Vriska

“Hnnnng John, hurry up!!!!!!!!” There’s a lot of fumbling and rustling on John’s bed as Vriska squirms, flushed and naked and waiting for John to wiggle out of his own clothes. Vriska gets tired of waiting for John to peel off his suit and props herself up on the bed, reaching forward and letting her hand rest against the noticeable bulge of his slacks before quickly unzipping them. She hesitates for a moment before slipping her grey hand inside and fumbling to pull out John’s dick between the fly; it takes a few minutes for her to properly grasp the spongy flesh, but once she does pop it out the tight confines of John’s pants she lets out a little ‘ah-ha!’ before her mouth turns into a small ‘o’. Peering down at his girlfriend, John feels his face burn as he takes in Vriska’s surprised expression, and he sheepishly rubs the back of his neck,

“Oh, gee sorry if it’s smaller than you expected Vriska. But I’ll try really hard to make it good!” Vriska can feel the muscles in her face tighten as she frowns, looking at the bobbing monster before her. If that was what humans considered small what the hell was big?  It’s not like it’s the size of her arm or anything, but it’s a lot bigger than troll bone bulges, all twitching and throbbing with thick, pulsing veins, and don’t even get her started on the hairy shame globes. But she’s already come this far, there’s no backing out now, she was a Serket damn it! Shaking her head, Vriska puffs out her small chest proudly,

“It’s fine John, I can make do with it!” It lacks her usual bravado but John seems none the wiser, eager to climb back atop Vriska and pop her nipple into his mouth. Melting into his touch, Vriska leans back, all too happy to let John run his tongue along her sensitive breasts and his hands slide down her thin frame to rest against her cunt where he rubs her a little too harshly but when she grunts a bit he’s quick to apologize and go softer. When he slips a finger inside her hesitantly, she gasps at the intrusion but feels no pain, and as he thrusts his finger in and out of her she can feel herself leaking more and more, her body burning with pleasure.

“John, come on already,” Her voice was low, laden with arousal and frustration at her boyfriend’s prolonged teasing. She could hear him chuckle around her breast as he pulled his finger out of her, replacing it with the head of his dick pressed right against her opening. Taking a few breathes to force herself to relax, Vriska closed her eyes, feeling John rise up to kiss her forehead and murmur encouraging words as he slowly guided himself in. Panting the grunting, Vriska bites her lip as John slowly pushes the head of his cock inside her slick opening; it stings but it’s not completely painful. She can hear John huffing above her as he struggles to go slow, hands holding her hips tight as he continues to push into her. Inch by inch he stretches her out, the farther he gets the more it starts to sting, the sensation of being stretched uncomfortable and unfamiliar to the alien girl. Her eyes are squeezed shut as the pain increases from a dull ache to a full blown stabbing pain in her lower abdomen. Holding back a whine, Vriska tentatively releases her grip on the bed sheets to rub at her sore belly, hands shaking as they brush over a growing bulge in her tummy and she lets out a shaky breath.

“Almost there, Vriska!” John’s chipper voice only brings panic to Vriska and she whimpers as John forces the last few inches of his cock into her cunt in one thrust. Trembling in pain, Vriska slides her hands onto John’s forearms, holding onto him for dear life as she struggles to adjust to his length. Too proud to admit how painful it is, Vriska inhales deeply before placing her hands on John’s cheeks, bringing him down to kiss her and hopefully keep him still enough for her to get used to him. He moans softly, but his hips start to rock slowly until he breaks the kiss and slides his cock partly out of Vriska. She hisses between clenched teeth, hands slapping down on John’s shoulders as her legs shake on either side of John’s body. When he slides back into her, dragging her body by the hips to meet his own, her nails dig into his pale skin leaving welts, a strangled yelp caught in her throat. It feels like she’s being split in half, her body straining to stretch around John’s dick to the point that the head has left a visible bump in her lower belly, bulging the once flat skin. Confusing Vriska’s muted whimpers for ones of pleasure, John starts to pick up the pace, thrusting faster and sloppier, leaving Vriska to writhe underneath, raking her nails down his back and biting into her lip so hard she drew blood to distract herself from the pain. Until finally, gloriously, she could feel John completely lose rhythm, bucking wantonly into her and burying his face in the crook of her neck, whispering how much he loved Vriska as he came. Even as he slipped out of her, it was painful, her pussy sore and throbbing and her stomach cramping, and while John rolled from off of her to the other side of the bed she clutched at her tummy and sniffled. Human sex was fucking barbaric, what kind of species put their flushed lovers through this?
