Mirio stared down at the girl lying unconscious on the bed in front of him. It was Eri, the girl they'd managed to rescue from Overhaul, thanks to the help of so many heroes, particularly Izuku, an underclassman of the boy.
He was staring down at the girl as her small chest slowly rose and fell. She had been given a drug to sleep to keep her powers from activating until they knew for sure she would be fine. It meant she would be knocked out for a while, and it was also late enough that it was unlikely they'd be checked on for a while.
Mirio also knew that this room didn't actually have any cameras, and was therefore only a temporary room before they moved Eri to a place where there was one.
All those factors led to this once in a lifetime opportunity for Mirio as he slowly started undoing his pants with one hand while the other was grabbing Eri's hospital blanket and slowly taking it off.
She was dressed in a hospital gown with a pair of underwear included, leaving her in only two articles of clothing. He could already feel his heart racing as he dropped the pants and boxers to his ankles a few moments later, and stepped out of them.
If he still had his quirk, he could simply phase out of them, but he didn't. His powers were gone, and although it had struck a mighty blow to his sense of purpose, he had another thing on his mind at that moment.
He continued stripping, taking off his socks and shoes as well as his shirt, wanting to feel every inch of his skin touching the cold air inside the room as he loomed over the unconscious girl.
He swallowed hard, his dick already semi-erect as he used his hands to gently twist her body and undo the strings on the gown. It didn't take long to get it loose, and after her gently set her back down, he grabbed the top of the gown and slowly pulled it down and off her body.
His breath hitched when he saw her chest. She didn't yet have a woman's body, instead leaving her more rectangular, and more importantly, her chest completely flat, other than two small pale pink nipples atop her small frame.
Exactly how he liked them.
It was always a secret Mirio had kept deep down, and was also part of the reason he'd never inclined to date anyone, even though he had been asked out several times. His interest was not with the curvy, beautiful people of his own age, but rather the pure softness and cuteness of those far below.
Like the perfect girl laying before him.
Her breathing was soft and slow, and as Mirio imagined those tiny lips wrapping around his cock, he grew to full mast, an impressive seven inches that was ready to be touched, or to go inside something.
He reached out and placed both hands on her chest, letting out a sharp gasp at how soft her skin was under his palms. Even if she didn't have any breasts yet, there was still a soft sensitivity there that he treated with gentleness. He gave special attention to her nipples, rubbing them between his fingers, his cock pulsing with want and need as she felt them starting to harden.
Mirio knew he honestly could've stayed there groping Eri's chest all day, but there was another treasure he wanted, so he removed his hands from her chest and slowly hooked his fingers into her panties, just a plain white cotton pair that he slowly started tugging down her legs. His lips felt dry as his heart raced with anticipation, until he finally saw it.
Of course, she had no pubic hair to speak off, and as the panties slid past her treasure, he felt a deep shudder run down his spine. It was the girl's pussy, tiny and cute and pink and perfect. It was all closed up, looking so small that it seemed almost like a different organ from the porn you could find online.
His excitement only grew when he pulled the panties off completely and left Eri completely nude. He gazed upon her beautiful body before grabbing his phone and taking several dozen pictures from every possible angle, even including his cock in some of them.
Now, he knew he wouldn't be able to do all his dreams. He lived for the day he could make a little girl suck on his cock while looking up at him with innocent eyes, wondering if she was doing it right. With Eri's unconsciousness, that wouldn't really be possible, unfortunately. He also knew he could jerk off on her and finish that way, but that wouldn't quite scratch the itch. He would need more, and so he would go all the way.
Mirio set his phone up somewhere to record everything, which he could then use alongside the pictures as future material. He then moved over to her and gently picked Eri up off the bed, her body feeling limp in his hands. At the same time, however, she was so light and soft.
And her butt, the sight of it sent his body into overdrive. He made sure to hold her up in front of the camera as he caressed her beautiful petite asscheeks, before then sliding his cock between them and shifting her body up and down. He trembled with pure lust and pleasure as his cock throbbed in response to the softness of her ass against his heat and hardness.
It was exactly as good as he always hoped, always dreamed it would be, and he had to stop before he blew his load too quickly. He took a few deep breaths to calm himself a bit as he sat down on a chair facing the camera and placed her on his lap. His cock rested against her back as he played with her nipples, and his cock stirred.
He reached one hand down and slid it against her slit, feeling her tiny lips spreading for it as he started to stroke her. He closed his eyes to enjoy the sensations of her pussy on his hand, her chest on his other, and her soft behind on his thighs, as well as the cock against her skin.
Eventually, he felt it, faster than he'd expected. She was growing wet, and her breathing was hitching a little, her brows furrowing. He smiled wide as he slipped his finger inside her, slowly thrusting it in and out. She was so tight as her walls clamped around his finger, as if trying to eat it. He could feel her getting more and more wet as he gently kissed her neck, pinching and twisting her nipple as she continued to moan in her sleep.
He even added a second finger and started speeding up, moving faster as he opened her up, her body shifting with his movements. He wished he could truly hear her making loud moans, but knew he would have to settle. He made sure the camera caught it all.
Before long, she had cum. Her body bent back as she made several lewd noises, and Mirio felt her spraying onto his hand for a few moments before she settled back down, her breathing still rapid. He took a deep breath and exhaled.
She was ready.
He removed his hand and put both of them around her waist to lift her up and position his cock against her entrance. As soon as it touched her, he felt a deep tremor run through him, and it became clear he wasn't going to last much longer. Even so, he knew whatever he was about to experience was going to be one of the best things he'd ever done.
So, after a few breaths, he lowered her down. His head went inside her, and it felt like he had died and gone to heaven. She wrapped around him so tightly that he almost didn't want to move. He swore he could feel her hymen, the thin wall inside her, and he took a few more breaths before plunging deeper. Eri cried out, but of course, stayed asleep. He felt something running down his cock, but didn't look, as his mind was too lost in pure bliss to even care.
He went deeper inside as he started shifting her around, moving her up and down on his cock since she obviously couldn't do it herself, and doing that instantly increased the pleasure tenfold. Her wet, tight walls sliding against his cock was pleasure previously unimaginable to him, far surpassing any masturbation session or sex toy he had ever used. He was already having to hold himself back from finishing right then and there.
He held strong, however, and kept going, sliding as much of his cock inside her as he felt safe doing before he resumed thrusting her up and down, up and down, slowly gaining speed as his cock felt ready to burst at any moment. He grit his teeth as Eri's breathing enticed him further as her small undeveloped body just felt too good for him to stand, and he only managed a few more minutes before he came.
Mirio erupted inside her without worry, as she was too young to get pregnant, feeling his cum fill every inch of her insides as he let out everything he had with glee. Pure bliss unlike anything he'd felt before filled his core and rushed through him, making him feel as if he was on drugs.
Unfortunately, it only lasted a few seconds before he was done, and the world was starting to rush back in. He quickly stood up, carrying Eri back to the bed.
He cleaned everything up, including Eri, before gently sliding her clothes back on and placing her back in the bed. He put her blanket back on and got dressed. He knew that ultimately, he probably had enough time to do more, but he didn't want to risk it more than he already was. Instead he took a deep breath to calm down before leaning down and pressing his lips to Eri's.
Her lips were small, soft, and warm, and he wasn't actually sure how long he spent kissing her, as it felt like minutes before he pulled away and ran a hand through her hair. He truly wished he could do more, but…perhaps once she was recovered, he could trick her into doing something for him.
Only time would tell.
For now, Mirio left, waving at her before opening and then gently closing the door, and leaving as if nothing had happened.
All while watching back the footage of his twisted dream having finally come true.
