A/N: I’m nervous thanks for coming to my ted talk
As you bounced up and down on your dildo, you buried your face deeper into the pillows on his bed, letting his scent fill your lungs. You had been infatuated with Shigaraki Tomura since the first time that Dabi had introduced you to him and the rest of the League, and at this point you were desperate. You had poked and prodded at him trying to gauge his reaction towards you, flirting shamelessly and snuggling up close to him every chance you got, but he never seemed that interested. You were so tired of waiting and so needy for him that climbing into his bed and humping at your toys while smelling him on his pillows felt like the only logical option at this point. You moan as you glide too far up the dildo, it makes a soft shulcking sound as it slips out of your sopping cunt. You whine into the pillows, reaching your free hand down to slip the silicone dick back into you. You buck your hips into the mattress, feeling your ass jiggle at the impact with the soft surface. You want so badly to cum. You want so badly to cum for him.
"Tomura-aah," you moan at the friction of the faux cockhead inside of you and your clit against the bed. Panting, you continue your thrusts, whining out for Shigaraki again, "Tomura- ugh fuck- please I-I need you, please," you nuzzle deeper into the pillows, "ple-please fuck me."
You start to pick up the pace, the hot spring in your lower abdomen stretches out and is on its way to snapping when a voice interrupts your frenzied, needy thrusts.
"What the hell are you doing?"
You flip over quickly, pulling the sticky toy from your slick folds and clamping your thighs together. And as though your pleas had summoned him, Shigaraki was standing there; framed menacingly in the doorway, his crimson eyes boring into the depths of your soul from between his Father's fingers. Your blood runs icy, unable to move a muscle or say anything, you stare back, a look of shame etched into your features. He steps into his room and closes the door.
"I asked, what the hell are you doing?" He snarls at your lack of answer.
You take in a shuddering breath, "I- I was- I was just-"
"Just what? Who the fuck told you that you could be in here?" Shigaraki's voice sounded dangerous, like the wrong answer would result in something that only one of you would enjoy.
You shake your head, "No one, I was just- I don't know know, I was just lonely I guess," the words tumble quickly from your mouth, your extremities were icy but there was a persistent warmth in your face and- in despite of (or maybe because of) the embarrassment- in your lower belly. "I-I'm sorry…"
He scoffs at you, strolling over to his desk, he keeps his back to you and does something you can't quite see in the dim light. Shigaraki turns back towards you this time without Father adorning his face. This wasn't the first time he had shown you his face, but even so the sight still managed to take your breath away all the same. His beautiful eyes were practically glowing as he glowers at you. You feel your breath hitch in your chest and the walls of your pussy constrict around nothing as he stares you down. His eyes narrow at you.
“You’re not sorry that you did it though, you’re only sorry that you got caught,” one conner of his chapped lips turns up slightly at your visible discomfort. Your heart races at how pointedly he spoke, you knew that you were probably in trouble with him, but you were still unsatisfied and in need of release, and he was so gorgeous that you could barely focus on anything but Shigaraki and the pulsing heat between your legs. You couldn’t take your eyes off of him as he approaches you, placing a gentle hand to your cheek, grazing his scarred knuckles over the plump skin of your face. You lean into him slightly, breathing out and letting your muscles relax against him. The warmth is gone and you have to steady yourself quickly before you fall off the bed as he snatches his hand away.
“Whatever. Just finish what you started, then you can leave,” he moves back to the desk and you let out a small pathetic whine at his departure. “Shut the fuck up. You’re lucky I’m even letting you do that,” He slumps down into his chair, still facing you and you can’t help but notice the bulge in his jeans. “Well?” Shigaraki poked incredulously, “I don’t have all night.”
Your face was so hot and your limbs felt like they were starting to go numb, but even so you slid onto your back, angling yourself so he could have a better view, your cunt was aching for a cock that wasn’t fake and you were hoping so much that if he watched you then he would maybe touch you.
Tomura let out a small laugh as he watched you position yourself, “Shit, you weren’t kidding when you said you ‘needed’ me, huh?” His dry cracking lips curled into a cruel smile at the expression that you made.
Shit.
He had heard you. It felt like your stomach dropped through your back and to the floor. It was unbearable now, you pulled your thighs to your chest, giving Shigaraki a perfect view of both of your holes. Spreading the lips to your entrance, you push the head of the dildo back into your still drenched and clenching heat. You let out a small gasp at the ache that the hard toy leaves you with, a wave of pleasure washing over you as you advance the cockhead deeper inside you, smoothing over your gooey velvet walls. You start to pump the toy in and out of you, the lewd squelching and soft moans fill up the silence in the room, your eyes never leaving Tomura’s face. Your eyes were glazed over watching him, taking in every drop of his beauty. With this, you notice that he’s breathing heavy and staggered, a small trail of drool found its way past his rough lips. He swipes the cuff of his sweatshirt over the salivation, those crimson eyes still piercing unwaveringly into you, watching everything you do. He fumbles with the fly on his jeans for a moment before pulling down the waistband of his jeans and his briefs, his large cock no longer sheathed fully in its foreskin bounces free and strains against his stomach.
You gasp at the sight. Compared to both the toy inside you and previous people you’ve been with, he easily dwarfs them. You stop pumping for a moment to gaze longingly at it.
“What?” his voice is sharp and unforgiving, “Did I tell you to stop?”
You breath caught slightly in your throat, “You- you’re bigger than I thought…” the words fall from your lips before you can stop yourself.
He lets out a barking laugh, “Whatever, just hurry up.” Still, you couldn't help but notice his cock twitch at your words.
You continue your initial assault on your hole, still unable to look away from the sight in front of you. Shigaraki started to pump his large member in his fist, small beads of precum leaking from the deep red tip. A moan found its way from your throat as you watched, aching and desperately wanting him to plunge into you and replace the stupid piece of plastic that was currently occupying your pussy. You moved faster, hoping that the added friction would make up for the size difference, but either way it wouldn’t have mattered, you knew you wouldn’t be satisfied until you had the real thing.
“Sh- Shiga- Shigaraki, please…” you buck your hips into your hand and try to get the toy deeper inside of your clenching cunt. “Please fuck me, Shigaraki... “ now that he was actually in the room with you, there could be a chance that you could sway him to pound you into the mattress.
A harsh backhand landed across the ample cheek of your ass, his long nails leaving small red scratches on your backside. You groan and throw your head back at the pain, but the feeling of his set to send you into a tailspin, you pussy clenched hard around the toy, ushering another moan from your lips as you continue to drive the dildo in and out of yourself.
“Shut up, I already told you, you have to finish what you started,” he pulled back to his chair. "Besides, it was cuter when you called me 'Tomura'."
You whine a little as you thrust into yourself harder, on every pull you could feel the molded head of the toy rub your sweet spot. The coil of heat in your belly starts to tighten again, and having Shigaraki there made it all the better. You were teetering on the edge at this point, the pain from how hard the dildo was and how it stroked your walls combined with his prying eyes made you lose your sense.
"T- Tomuraaa-aahhhh" your walls clamp down hard on the dick inside you, sending you into a shuddering orgasam that wreaks through your body, your arm was moving of its own volition, keeping the dildo moving as you rode through wave of pleasure after wave of pleasure. You didn't want to stop, you didn't want to think what would happen after you finished. The intense clenching made it impossible to think, and without realizing it, you were squirting all over Tomura. Your ejaculate splashing onto his face and cock, and into his slightly open mouth, he let out a sharp breath at the sight.
Of course he had seen people in porn squirt like that, but he hadn't imagined that you, with your incessant pestering and bothering, would be moaning his name and spraying all over him like an animal in heat. And the real kicker was, as much as he didn't want to, he loved the scene that was unfolding before his eyes. He gripped himself tighter as you continued to abuse your own hole and moan his name. Your stream of juices tapers off and he can't help but feel a little disappointed he wasn't able to taste more of that nectar that landed on his tongue moments ago.
You let out a shuddering gasp as you come down from your high, your legs shaking as you tug on the dildo. The constricting of your pussy has it much more difficult to get out than it was a few minutes ago, but nonetheless, giving a more solid pull the toy pulls out, a wet popping and a small flick of your wetness accompany the removal. You sit there for a moment, basking in the post bliss of your orgasm when the sound of Tomura clearing his throat loudly snaps you back to reality.
You sit back up and pull your underwear and shirt back on quickly. As you're standing up to leave, he clears his throat again. You freeze, your back to him.
"I don't know where you think you're going," his voice was low and stern. You turn and face him.
"You said to finish and then leave…" and as the first words left his mouth you realized what he was talking about.
"I told you to finish what you started. You started me up," he gives his cock a few strokes for added effect and smiles at you again, "now you have to finish me."
