Work Text:
“Alright go to your pairs and work on the assignment, it’s not due until next week, now I’m going to sleep” Aizawa grumbles before getting in his sleeping bag and going to sleep. You watch as Deku walks over to your desk pulling one of the now empty ones next to yours, “H-hi Y/n ready to get started?”
You grin and nod, “Yeah,” you notice that no one else is sitting in the last two rows, all having moved upfront to their partners instead. Weird
You shake your thoughts and you both look over the assignment after a few minutes you lean back stretching but you can’t help it when your vision wanders after Izuku scoots back and leans his chest forward to look at the slip of paper in front of him.
You knew your boyfriend had ass but sometimes it catches you off guard when he sits or stands a certain way. You watch as the seams stretch trying to contain the bubble butt your cute little boyfriend hides under his clothes and you bite your lip with a groan caught in your throat.
You check his ass out a little more, so lost in your dirty thoughts you don’t hear Izuku trying to talk to you until he turns around and sees where you were staring.
“Y/n?” Your head snaps up and you nervously cough scratching the back of your neck after you notice he turns bright red.
“Oh sorry I uh I got distracted” you internally facepalm at being so easily caught thinking about your boyfriend's ass.
He giggles, “I can tell” he smiles before continuing talking to you about the assignment. You try to pay attention, you really do but every time he shifts in his seat you can see the strain against the seams of his pants. Before you can even contemplate your actions your fingers are dipping in the waistband of his uniform causing him to squeak as he looks back at you.
His voice is hushed as he speaks, “What are you doing?” his eyes are wide, a blush on his cheeks as he shuffles in place. You just look up a small smirk on your face as you flip your hand so your palm is facing his back and you slip your hand further.
“Shhh” you smile leaning forward so your arm is hidden behind his back, you make sure no one from this angle is able to see anything as you lean against his shoulder.
As your hand moves you feel the small shiver wrack his body as he exhales shakily, “Y-y/n we shouldn’t- what if someone sees” he mumbles as he looks at you.
“If you're quiet we have nothing to worry about, if your good I’ll fuck you with the strap until you break tonight, after all, we got all weekend to recover” you mumble against his ear as his eyes flick rapidly around the room looking for watchful eyes. You lean down pulling out your hand to coat your fingers in spit before slipping your hand back in.
Izuku whimpers as your wet middle finger rubs against his pucker, his body reacts against his will and grinds back trying to get the digit to enter him. You feel a rumble in your chest when he bites his lip and looks at you, his face flushed and his eyes already glazed over with lust.
You decide to stop teasing and push the digit in as he wiggles his hips in place, he instantly reaches his fist up to press his teeth against his knuckles as he clenches his thighs together. You watch the room making sure nobody looks back and begin to curl your finger to rub against his walls.
“O-oh” he moans quietly, his hips pushing back as he leans his chest forward further, his back arching deliciously. He starts slowly grinding his hips back as you thrust your finger in and out of his hole. Adding another finger you pick up the pace a bit more being careful and avoiding making any noises with your thrusting.
Izuku whines in the back of his throat as he puts his head down against his arms. His fists clench and unclench repeatedly his legs bouncing rapidly. Adding a third finger you give him a second to adjust. You feel him clench tightly around your fingers and you clench your thighs together feeling more and more hot and bothered by the display in front of you.
After a couple of seconds, you feel Deku start to push back on your hand, you almost groan out loud at how his hole flutters repeatedly around your fingers. You check the time seeing you have a bit left of class and don’t have to worry about it yet. Lucky for you two this is the last class of the day and you can head straight to the dorms.
Izuku whines a bit louder than you expected and your head snaps up to see if anyone heard before sighing when everyone is still focused on their work.
You lean down to his ear, “Be quiet bunny or I’ll stop and leave you hanging” you nibble on his ear as he clenches harder. Moments like these you wish you had a dick so you could feel his warm insides tighten around you.
His head turns to the side, his head still against his arms, and looks at you, and god you swear the sight in front of you could make you cum right then and there. He has tears in his eyes as his bottom lip trembles, red and swollen front biting it so much, and drool drips down his cheek.
“P-please mommy” he mumbles quietly and you cross your legs, your other hand clenching in response. You watch his face as you curl your fingers up brushing his prostate. His eyes roll up his hips pressing back hard and his jaw going slack a long shaky but luckily quiet mewl leaving his lips.
You see his thighs quivering and his hips wiggling a telltale sign he’s close and you glance up to the clock seeing the class about to end. You grin, deciding to test your luck and start thrusting faster the tightness of his pants muffling the sounds as Izuku slams his hand over his mouth his entire body shaking as his eyes cross. He pushes back harder against your hand, his legs lifting off the chair, his toes curling in his shoes. You push hard into his prostate as the bell rings and he cums with a loud but muffled moan, luckily the bell covers it up and you watch as everyone leaves. Izuku has his head down and you slip your hand out of his hands, placing it on his back as the self proclaimed “Dekusquad” approaches.
“Hey Deku you okay?” Uraraka asks as the rest look at him concerned.
“Y-yeah just don’t um feel good you go ahead without me” he waves them off with his hand.
“Okay if you’re sure feel better” after a few more get well soon from his friends they say bye to you both and head off. Aizawa’s still asleep and you stand up packing both of your guys’ things before kneeling in front of him and petting his hair.
“Can you stand baby?” you whisper and he lifts his head nodding standing up
“Did I do good?” his doe eyes just melt your heart every time you look at him and you smile pecking his lips, “You did amazing love” you lean down to his ear, “I’ll show you how good back at my dorm” he shivers, bouncing on the heel of his foot before picking up his bag.
“Well let’s go!” he has a pep in his step as he walks to the door making you chuckle at his obvious excitement. You grin grabbing your backpack and following him out, you both feel the brewing tension as you walk to the dorms. Said tension triples as you get in the elevator to go upstairs.
You press the button to your floor, as soon as the doors shut you turn pressing him to the wall and kiss his neck. He whimpers, gripping your shirt as he tilts his head to give you more access to his neck.
“Please- fuck” you smirk biting hard on the spot under his jaw and he moans. You pull back and kiss him roughly as his arms slide around your neck. You grind your hips forward feeling him harden in his pants again.
You hear the ding of the elevator and you both quickly separate ecstatic giggles leaving both of you as you walk to your room. You both laugh as you quickly push him into your room and pick him up turning around pinning him to the door as it closes.
You both lean in slamming your lips together as you make out, your hands drift to his ass giving it a squeeze as you bite down on his lip. He moans his legs tightening around you as he pushes his ass back into your hands. He unbuttons his shirt and you turn around walking to your mattress and set him on it.
“Strip baby” moving over to your closet going inside you grab your strap and lube before walking out and freezing at the sight in front of you. Izuku is face down on the mattress, both hands spreading his cheeks so you can see his winking hole.
“Oh fuck Zuku” you groan looking at him with pure desire in your eyes. You set the stuff off to the side before reaching your hand up to grope his ass, “Have I ever told you, you have the nicest fucking ass .” you squeeze them again before giving in to your own desire.
You lean down pressing your face into his ass and shove your tongue inside his hole. Izuku moans loudly, his toes curling as he humps back against your face. After a few minutes of tongue fucking him he starts whimpering louder, “Close mommy close!” immediately you pull back, wiping the drool off your face with the back of your hand.
“Noooo why’d you stop” he whimpers looking at you over his shoulder with pouty lips.
“Don’t you want to get to the main course?” you lift up the strap waving it in front of you, a knowing smile tugging at your lips when his pupils blow and his tongue swipes over his lips.
“Yes please mommy” he arches his back further wiggling his ass in the air as he looks back at you with a fake innocent look. Fucking brat
You hook up the strap to your hips before positioning yourself behind him, as you lube up the strap you look up at him, “Since you were such a good boy how do you want me to fuck you bunny?”
“Fast and hard” he grins spreading his legs a little more and pushing his hips up further.
“Sounds good to me” you grin and press the tip to his entrance watching his face pinch up in pleasure when the tip finally catches on his rim. You hear his breath hitch as you slide in till your hips are flush against his ass. You planned on waiting for him to adjust but almost immediately he pulls forward and pushes back about halfway before looking at you again with a mischievous look on his face.
“Fuck me mommy” he shoves back the rest of the way onto the toy harshly a pathetic sound leaving his throat.
“God, you don't even wanna wait, such a cockslut huh bunny?” You punctuate your sentence with a hard thrust and smack on his ass.
“Y-yes!” he moans, his head thrown back as you pick up the pace, he thrusts back quickly matching your pace as he fists the sheets.
You reach a hand down squeezing his ass roughly, “Such a nice ass bunny, so distracting though you know that? Can’t get through a class without thinking about this delicious ass” you growl out the last couple words as you shift on your knees to pound him even faster.
Izuku keens shoving his face into the mattress as he squeals. You reach your hand forward yanking his head up by his hair. He moans again, his mouth open having lost the ability to even think about closing it.
“Oh god mommy~” he whimpers, spreading his legs a little further. You groan seeing how needy he is and you move forward grabbing his shoulder pulling him up so his back is against your chest. At this angle, you can feel his ass bouncing against you with every thrust and you groan at the feeling.
“FUCK MOMMY” his eyes cross and his tongue lolls out as he scrambles to grip your arm which slid to hold him via chokehold. You press your forehead to his shoulder looking between you to watch the toy slide in and out of your boyfriend.
“What am I gonna do with you baby, with such a fat ass and knowing how easy it is to make you cry out like a slut how am I ever supposed to resist you”
He attempts to respond but can only gurgle and whine as he starts crying in pleasure. You grip his throat with your hand and shove his head back onto your shoulder causing his back to arch further.
“M-m-mommyyyyy ‘m clooose~” you can feel the fat tears slipping down his face onto yours as you nip and kiss at his Adam's apple.
“W-wanna cum please, pleasepleaseplease” he whimpers his voice breaking.
“Yes, sweetheart you’ve been so good cum whenever you want” you lean back to watch his face as your other hand reaches around to stroke his leaky cock.
All it takes is 3 strokes and tightening your grip on his throat, he cums with a scream of your name as he spills over your hand and his chest, some shooting onto the sheets at the edge of the bed as well.
“Mommyyy, feels so g-good” his eyes are having trouble staying straight as he slurs and slumps back against your body. You help him ride out his orgasm before carefully pulling out and shifting you guys to lay properly on the bed.
After laying him down you lean over him and comb your fingers through his hair, “You okay baby? Was that too much”
“Was amazing” he mumbles, opening his eyes to look at you a satisfied smile pasting itself onto his face. You sigh in relief leaning down and kissing his forehead, “Let me go get a wet rag to clean us up” you kiss him once more before grabbing and wetting a rag bringing it back. You quickly wipe your hand and his chest before moving him away from the spot of cum on the bed.
You climb into bed behind him pecking the nape of his neck, “I’m glad you trust me so much with this stuff love” you smile against him and pull him back into your chest. You cuddle back into you with a content sigh his arms overlapping yours, “Anytime Y/n I love you”
You can’t help the blinding grin that crosses your face as you mumble an “I love you too” back to him. You both drift off pretty quickly your warms bodies against each other soothing you both to nice dreams.
