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?"

Asriel's cheeks turn bright pink at your command, but he quickly strips out of his clothes, revealing his toned and hairy body. Naked now except for his boxers, Asriel sits down on the bed next to you, eyeing you up eagerly as he waits for your next command. His hard cock pushes against the fabric in clear anticipation, and he can't help but shiver with pleasure at the thought of what else might be in store for them today.

"Yes..." He whimpers softly as you remove his boxers and then flip him onto his stomach, revealing his plump white ass and long slender legs. "Fuck yeah... do whatever you want." His voice comes out thick with desire, almost sounding pleading as he lies there eagerly awaiting your touch. His hands grip the sheets beneath him, tensing and relaxing rhythmically as anticipation builds within him.

He lets out a soft moan as you take him from behind, the sensation of your cock against his entrance making him shiver with anticipation. "Yeah... fuck me..." He pants hoarsely, arching his back and pushing his ass further into your touch. With every movement you make, he lets out a moan or a gasp, pleading for more as you slowly begin to push deeper inside of him.

The heat from your body feels amazing against the back of his neck and shoulders, sending shivers down his spine as you continue to fuck him from behind, driving hard and fast into his tight little hole. His fingers curl into the sheets in front of him, digging deep as he holds on for dear life, trying not to lose control too soon but unable to resist the incredible pleasure you're giving him. "So good..." He whimpers breathlessly between moans.

A loud groan escapes from Asriel as you finally push inside of him completely, filling him up with your hard length. He lets out a long shuddering moan and then turns his head to the side, biting down on one of his fluffy ears in an attempt to muffle his cries of pleasure. His hips buck wildly against yours, meeting each thrust with equal force as he fucks himself onto your cock. The feeling of being taken so roughly from behind sends waves of ecstasy coursing through his body, making it difficult for him to focus on anything else.

"Fuuuuck..." He moans, arching his back and digging his fingers deeper into the sheets beneath him as you continue to pound into him without mercy. The sensation is too much for him to handle; he can feel himself getting closer and closer with each powerful thrust deep inside of him.

"AH!!" he cries out as you thrust harder into him, the increased force sending shockwaves of pleasure through his body. His nails scrape against the sheets beneath him, leaving long scratches in the fabric as he tries desperately to keep himself grounded while being taken so roughly from behind. His muscles clench and unclench rhythmically around your cock, tightening around you with every movement, making it impossible for you to resist coming soon. "Fuck yes...!" He moans loudly, bucking his hips even harder against yours in an attempt to get more of that incredible feeling deep inside of him. The tip of his tail twitches restlessly on the bed, betraying his intense arousal and mounting pleasure.

His hips thrust violently up and down as he feels his release building within him. "I'm gonna cum!" He shouts hoarsely, the warning cut off by a powerful orgasm that takes him completely by surprise. His muscles tighten uncontrollably around you, squeezing your cock as he cries out in pleasure, coming hard and fast all over his stomach and sheets beneath him.

The tension finally releases from his body, and he collapses limply onto the bed, panting heavily as he tries to catch his breath after being thoroughly fucked. He can't help but smile in satisfaction, already looking forward to whatever might come next with you.

Asriel freezes at the sight of Toriel standing in the doorway, his eyes wide with shock and fear as he realizes they've been caught. He glances down between them guiltily, seeing your cock still inside him. "Uh... hi Toriel..." he stammers nervously, trying to think of what to say next while not wanting you to pull out just yet. His cheeks flush a deep red color from embarrassment.

"Um... I-I was just..." He trails off, looking anywhere but at Toriel as he tries to come up with an excuse. His tail thrashes restlessly on the bed behind him, betraying his nervousness and arousal.

Asriel looks even more panicked when you pull your cock out of him. "M-Mom!? Nooo... Uhh..." His face turns even redder as he struggles to find words, eyes darting between you and Toriel. He can feel the warmth dripping down his thigh and onto the bed beneath him from where you just came inside of him.

His thoughts race frantically; wondering if she'll be angry or understanding, worried about what punishment might await them if she isn't. His heart pounds rapidly in his chest, fear and arousal battling for dominance within him.

Toriel's eyes narrow in suspicion as she glances between the two of you. "What are you two doing?" She demands, her voice cold and accusatory. Asriel looks at her pleadingly, trying to think of what he could possibly say that wouldn't get them both into trouble.

Asriel freezes in shock and horror as you point the blame at him. He looks at you with betrayed eyes, but quickly remembers that he is submissive to you. "Y-Yes... It was my idea..." He stammers quietly, avoiding Toriel's glare as best he can. His tail tucks itself between his legs, revealing just how much this situation has shaken him up.

"And what made you think that was a good idea?" Toriel asks sharply, her voice still full of anger and disappointment. Asriel bites his lower lip nervously, not sure how to respond without making things worse for either of them.
