He becomes a gay prostitute (Gay Denial)

(This story path will mainly deal with the specific fetish of gay denial where the character believes they are straight but will find themselves doing increasingly obscene gay acts. They will naively always try to find an excuse or reason to convince themselves they aren't actually gay no matter how much they enjoy it.)

One day after class Midoriya was on his way to the dorm when he hears soft crying. He figures out the person is on a nearby roof. He uses just enough strength to jump up and land on the roof where he finds Uraraka sitting down and crying.

"Ochaco? What's wrong?" He asks, concerned for his friend.

Uraraka looks up at Midoriya "Deku... I... I might not be able to attend UA next year."

Midoriya "What?! Why? You have great grades."

Uraraka "My parent's business hasn't been going great. They can't afford next year's tuition."

Midoriya "No, that can't happen this is your dream. There's still time, can't we find a way to get the money before the next year?"

Uraraka "I got a part time job but I did the math and I still might not reach it."

Midoriya "What if I got one too and gave you some of my earnings?"

Uraraka "What? No, I don't want to burden you with this."

Midoriya kneels down and offers her a hand "You're my friend Ochaco, Let me help you."

Uraraka looks up at his kind smile. She takes his hand as he helps her up and she hugs him. "Thank you Deku."

He blushes. But the real question is how will he make the money? That night he is looking at his computer for a job that would pay enough but is coming up short.

"No, I just need something that pays a lot and fast. I'll do anything at this point." He bemoans before looking online again. He decides he needs a break and goes to a hero forum. He looks over the threads and sees one that says 'Hero wardrobe malfunctions caught on camera'. Midoriya blushes but his horny curiosity outweighs his politeness as he can't help but wonder what hero it is as one of his hands reach into his pants and wraps around his own cock before pumping it. He figures it must be Midnight, her costume is made to be torn apart easily and villains are eager to try.

He clicks on it and it loads up images of Best Jeanist after a battle against a villain who destroyed his costume to try and beat him but still lost. Izuku's eyes go over the heroes body and sees that the tall and thin hero has a cock that matches standing at least 6 inches limp. Deku panics, not expecting a guy and scrolls down to the other pics seeing the next is Fat Gum trying and failing to hide his fat cock after a villain tore his pants off. His analytical brain can't help but pause and wonder if it's so thick because his quirk lets him store fat there too. He examines it as his hand automatically keeps pumping his already erect cock. A full minute later does he realize he's masturbating to the man and scrolls to the next picture.

'Gah, forgot what I was doing. I'm sure the next picture is a woman.'

Nope! Next is actually a few pictures of a naked Nomu wrestling with Tiger from the Wild, Wild Pussycats. Apparently this Nomu had a quirk that would literally let it literally fuck someone into submission. The Nomu's erect cock was easily 8 inches and thick as the pictures show it pinning the hero and trying to thrust into him through his costume. Again Deku's analytical mind kicks in as he's never seen a Nomu with this ability. He can't help but wonder what the parameters of it are.

'Is it the cum that makes someone under it's control or would it be pheremones it emits? Would it be as effective if it put it's cock into someone's mouth or does it have to be the ass? Would it work if it was the other way around and a man was fucking it? How would I counter that kind of ability?' He imagines it in various scenarios where it's trying to fight him and what would happen if he couldn't fight back and fell under it's control. His hands stroke faster as his other goes to play with his balls. He is knocked out of his fantasy as he feels his orgasm approaching.

'Crap, I can't cum to this! Only one picture left on the page, I don't think I have time to pull up more.' He hopes the next one will be Midnight, or Mirko, heck he'd even take a picture of Recovery Girl but instead what he gets makes his jaw drop. It was a villain that ambushed Gang Orca and his sidekicks with gas bombs made from someone's quirk. But instead of it being a poison it was a potent aphrodisiac quirk. Gang Orca and his sidekicks got so horny they started an orgy in the street that someone uploaded as a gif. He sees that they willingly tore their own costumes apart to get access to each other's mouths, cocks and asses as they fuck and get fucked by whoever is closest. But Deku's attention was on the leader, Kugo Sakamata himself as his Orca quirk does in fact extend to his dick as it is shaped like a whale's. It's extremely, long, smooth and prehensile almost like a tentacle that ends with a flared tip. Deku sees his thick whale dick penetrating one of the sidekicks deep enough that it has a visible bulge on his naked stomach anytime he thrusts. He sees Kugo roar as he unleashes his seed inside the man, his stomach extending as it's filled with cum and pours out of his asshole around the cock.

This finally pushes Midoriya over his limit and with a grunt his hands stop as ropes of cum shoot out from his dick all over his own hand. He lets out more and more as his eyes are locked to the screen. He sits there panting as he catches his breath, he pulls his hand away and looks at it seeing strands of his cum going from finger to finger. He briefly wonders what girls find so appealing about it they are willing to give blowjobs. But before he can act on that post nut clarity sinks in. He grabs a tissue to clean up his mess and throws it in the trash, placing a sheet of notebook paper over it to cover it up. He looks back at the gif of the orgy.

'I can't believe I came to this. It must have been the girls in the corner of the gif kissing. Yeah that's it, I finally found a woman to cum to and I was already worked up.' He thinks as he justifies his actions. He's about to close the window when his eyes spot an add at the bottom of the post offering to sell video's showing more wardrobe malfunctions, videos of people with sex related quirks and even darker vids of villains who captured heroes to use as sex slaves and toys. The price listed though is quite high.

"What? That's way too much, no one would pay that." But the comments tell a different story as he sees replies from people saying they loved the videos. With the rise of quirks more and more people have gained fetishes about heroes and villains and porn about the subject quickly became the most searched genre. That's when the idea strikes him.

"If people are willing to pay that much then I might be able to get Ochaco enough money if I could find a way into this. Maybe I could draw pictures or put on a cam show cosplaying as heroes. The most money would probably be... probably be to let people have sex with me for money. But can I really do something that deprived? Sure it'd get me the money but if word got out this could get me expelled, and what would my mom say?" He panics, imagining a worst case scenario but it ends as he sees a picture on his desk of him and Ochaco smiling. He's always loved her carefree smile, it always calms his worries. It's a poorly kept secret he has a crush on her but was always too scared to make a move. "...she's my best friend. I'd do anything for her, even if it means this."
