Testing the waters with Mina

Izuku realized his hands held the answer to if Mina or Ochaco - or anyone really - meant what they said to him. A part of him still was very **** to go around and use these perverted powers all willy-nilly, but a deeper part of him still craved validation, answers... Love... Desire... Izuku was never desired by anyone, and just the thought made him severely anxious but happy at the same time. He was always trying to be his best self, working hard every single day both as a hero and as a person, and seeing people recognize that felt incredible. And to think maybe, just maybe, people could appreciate him in more ways... It's just too tempting not to try and reach for it.

Plus Ultra...

"If Mina Ashido is attracted to Izuku Midoryia in a sexual or romantic way and willing to share him with Uraraka Ochaco, she'll start to feel very horny once inside her dorm. She'll quickly take off her clothes and touch herself, moaning just loud enough for Izuku to hear from just outside her door. It will feel better than any other time she's done it before, and it'll be very pleasurable. A couple seconds after Izuku has arrived in front of her door, she'll have a powerful orgasm. If she's not attracted to Izuku, she'll still get extremely horny but decide to take a shower, on which her horniness will subside."

"This is... Reasonable... I hope" Izuku closed the notebook and put it on his lap, trying his best to cover his erection. Even if this test was with the best intentions, he still felt incredibly dirty. It was unavoidable to imagine what was gonna happen. Or rather how it was happening. The way Mina would stop and notice her lust building up, nipples poking against her shirt and crotch feeling wetter. How she'd strip naked and reveal her pink curvy body to the hot air as beads of sweat mix with the running juices down her thick thighs. Or how her body would start shaking and trembling while her legs spread and her bouncy breasts jiggle with every movement, as her fingers slide in and out of her wet - "CALM DOWN! Don't get ahead of yourself Izuku!" The hero wondered if the note really didn't have any greater passive effects on one's libido, pacing around the room, waiting to calm down before heading to her room.

"Or maybe," trying to rationalize, the boy stopped in his tracks mumbling "I've given all my life to hero study and work, and given all the trauma that comes with it... My libido - maybe even everyone else's - might be... Fucked" There unfortunately wasn't another more proper word that Izuku could use to describe that feeling, seeing as right now he was starting to figure out his way towards Mina's dorm room. Even starting to regret more and more with each step making one of the conditions of his test to stand in front of her door - and listen in to potential moans and other lustful sounds coming from his best friend - there was no telling what would happen if he didn't go there. Would she keep on touching herself forever? Would the note **** him to walk to her dorm after a while?

Breaking from this thought process, Izuku managed to catch the elevator just before the door closed entirely. And he breathed slowly, notebook held on top of his crotch trying to hide his painfully erect member, trying to come up with a excuse to be heading to Mina's personal dorm room. "I'm gonna tutor her in math" would be too generic "We're gonna watch a movie" would be weird with a notebook "I'm gonna show her some of my hero notes" now that's interesting, but raises a lot of questions and people might wanna see...

Before he could come up with a plan, the door opened, and he stepped forward without even thinking first as he saw the empty corridors, and given his built-up excitement for the results of the test his rationale wasn't really in full command anymore. With each step forward Izuku question if this was really the right thing to do, if his expectations were too high and she was just flirting for fun, or if something went wrong and she found out he was the one behind it all or if something else went completely wrong...

The muffled excited moans from behind the wooden door were enough to shut down all of his worries, as his singular focus was on the way her voice bent and escaped her presumably covered mouth as Mina masturbated just a few feet before him, thinking about... Him. Desiring to have him in her arms, fucking her. And from the low buzzing and the wet sloppy sounds leaking through, he imagined this was a very special scenario she had in mind. Midoryia absent mindedly didn't bother to hold the notebook so tightly to his crotch, letting his throbbing erection breathe softly as the breathing rythim Mina seemed to have going on increased in speed and intensity. She was close to finished.

"D-d-deku-u-uuu!" She moaned softly, just loud enough for the man himself to hear, but to both of them it was like screaming to the entire world. Mina rocked in a tremendous orgasm with a high pitched muffled moan, likely due to her bitting into a pillow, but it was more than enough to Izuku seriously consider opening the door. He started backing away ever so silently, backwards into the elevator and towards his own dorm, praying to all forces that he didn't encounter anyone on the way. He could feel how red his face was and the way his cock hurt from how hard it was meant the notebook would barely be enough to cover up anything.

Fortunately, he managed to dodge anyone on the way to the dorm, and quickly went inside and locked the door behind. Nothing ever felt this intense before, especially such lust. It was... Amazing.
