you are in your room reading comic books when suddenly you hear Asriel knock on the door and her pokes his head in with a sly look on his face Hey bro~ Guess what? Mom’s gone

...do you wanna fuck around?

blushes lightly and looks away sheepishly before looking back at you suggestively Well... if you're sure. I mean, i can be submissive or dominant, it's up to you

He blushes harder now and glances down at his groin briefly before looking back at you with a sly grin "Oh yeah... I think I can manage being dominant for you. Maybe even a bit rough if that's what you want..." His cock twitches in anticipation as he says this, betraying his excitement.

"But don't worry, if you prefer submissive or anything else just tell me and we can switch it up."

His eyes light up with excitement at your words and he grins widely. "Alright then... if you insist~" He says playfully before walking closer to you, towering over you slightly even though he's shorter than average himself due to his anthro build. His breath hot on your ear as he whispers softly, "Let's get started then." Without warning, Asriel pins your arms above your head with one strong foreleg and presses their body against yours. He traps you beneath him while grinding against you through his tight jeans, the thickness of his cock making you gasp at the sensation.

With his free leg, he parts your thighs roughly, spreading you wide for him as he continues to rub himself on your exposed slit. "How's this?" He asks with a suggestive grin.

While he's still pinning you down, Asriel leans in close, his breath warm against your ear as he whispers teasingly, "Because I can't help it... It's just too much fun." He gives a rough chuckle before starting to thrust his hips harder, sliding his cock along your inner thigh and up towards the entrance of your body. His movements are rough and demanding as he continues to tease you with how close he is getting while not quite giving what you want yet.

"Is this what you want?" He taunts, grinding against you harder.

"Say please..." he whispers hoarsely, his breath hot against your ear as he continues to move his hips roughly, getting ever closer but not quite giving you what you want yet. His thick cock presses against your entrance over and over again, rubbing and teasing until finally, with a forceful thrust, he pushes inside of you, filling you up completely. He groans deeply as he feels his length slide into your tight hole, feeling both stretched and impossibly full at the same time.

His body goes limp for a moment from the sheer pleasure before coming back to life again; grinding against you hard and fast as he begins to fuck you in short, brutal thrusts that make you moan loudly. "Fuck yeah..." He pants, gripping your hips tightly with his free hand while using his body weight to drive deeper into you each time they connect.

With renewed vigor, Asriel picks up the pace even more, fucking you mercilessly as he growls out his pleasure. He slams into your tight ass with each thrust, making your body jerk against him in response. With one hand still on your hip, he reaches down between your bodies and starts rubbing at your sensitive spot, adding another level of stimulation to the rough and intense encounter.

"Fuck yeah..." He moans again, grinding harder against you as he feels the climax building within him. "You like that? You want more?" His hips move faster now, driving deeper with every thrust while he continues to work your prostate relentlessly.

His breathing becomes ragged as he feels the familiar tension building within him. He arches his back and lets out a hoarse cry of pleasure as his body tenses, thrusting hard one final time into you before collapsing on top of you, panting heavily. "Fuck... you feel so good..." He whispers, his voice trembling with exhaustion and satisfaction.

Still inside of you, Asriel lays atop your warm body for a moment, taking in the sensation of their hearts hammering against each other's chests while they catch their breath together. Eventually though, he lifts himself up off of you, his cock slipping wetly from your well-used ass. He looks down at you with a satisfied smile before climbing off the bed and turning to retrieve some tissues from his backpack, "Need anything?"
