Lawful Lewd

Midoriya Izumi's life, simply put, fucking sucked. Born without a quirk, she can to claw and scrape and kick her way to earn a fraction of what the other kids would get. Despite being the smartest in class, her grades sucked from the unfair grading. Despite doing literally nothing but nerd out with her journals, she would get bullied whenever spotted by the other kids in class. Every time she would look out the window and wistfully dream of being more than a quirkless loser, she would be harassed for having hope.

The closest thing she had to a friend was Bakugou Katsumi, a raving bitch of a girl who seemed to be perpetually on her period. Due to having a really cool quirk that let her create explosions in the palms of her hands with the only downside somehow being potential dehydration, she would be given all of the perks of being the entire school district's only hope of securing decent funding, and subsequently free reign of abusing Izumi. Katsumi even went as far as paying some old fat black bastard to **** her the moment Izumi turned eighteen, just to have the satisfaction of knowing that Izumi's only sexual experience in her life would be traumatic. The fact that Katsumi told Izumi to jump off a roof today just felt like salt in the wound, and her latest journal of hero notes and nerd shit being exploded and tossed out the window into a koi pond was the lime juice to round out the flavor of her suffering.

So, the Universe pitied her, and while Izumi was trudging along to fetch her notebook, she would witness a second notebook manifest out of thin air and lightly "plop" down onto the side of the pond. After grabbing it and looking around to try and find the owner, Izumi would read the cover and open the first page, just to see if there was any mention of the owner, but also to sate her curiosity.

But all she saw was that sticky-note that explained how this mythical notebook worked, and pages upon pages of nothing written down. In fact, as she flipped through them, she began to realize that an impossible number of pages fit in the book, almost like it was infinite! If she wanted she could probably have used The Book's pages to fill out her own notebooks, but she wasn't sure if that'd destroy The Book or rip a hole in time and space, so she shelved the idea for when she was feeling stupid and risky.

Regardless, she would whip out a pencil to test out this mythical "Rulebook."

*Old Rule: The Sky is Pink.

With that written, Izumi didn't expect much. Maybe another student coming out of the bushes to mock her, or maybe just for nothing to happen. And then she looked up.

Pink Sky.

Upon realizing the reality of the situation, Izumi erased the rule, threw the notebook into her backpack, zipped it as tightly shut as she could, and made a mad-dash home, eager to start rewriting the world into a better place. However, fate would deal her another bad hand as she was passing through an underpass. In an instant, a sewer-lid burst open as an escaping villain made entirely of sludge bursted forth.

"Whew, can't believe I fucking lost him. Hmm? Oh, perfect! A voluptuous **** puppet for me to make my getaway in! Don't mind if I do!"

Before Izumi could react, the slime engulfed her; groping her ass, tits, thighs, and probing at her pussy before entering with no other warning. Izumi's mouth was left exposed just long enough for her to let out a scream and a moan before the sludge would penetrate that too. For an unknown amount of time, Izumi was just stuck like that: getting throat and proper fucked by this villainous blob, but the part that yielded tears from her eyes was the fact that Izumi just got something that could change her life for good, and now it was in the hands of a villain.

A slimy tentacle pierced Izumi's ear, and began the necessary preparations for the villain to possess her. First, her hormones were altered, making Izumi more naturally perverse. Using this as a gateway for further mind-fuckery, the villain crossed Izumi's love for heroes and justice with a love for perversion, lewdness, and ****.

Now, Izumi was willingly sucking on the tentacle in her mouth, and her free hand was allowed to reach the tentacle in her ear, which she eagerly began to jerk off. The tentacle in her pussy continued its violation with little mercy, which Izumi then showed her gratitude for by squeezing the appendage with as much love as she could muster. Izumi was now a pervert getting ****, and she loved it.

Of course, the villain didn't touch specific details, memories, or anything else. He just needed to get Izumi in a perfectly submissible state so he could properly control her. Typically women didn't last as long as her, as their senses would be so overloaded that they'd suffer from a literal mindbreaking orgasm almost immediately; Izumi was close, but not close enough.

The manhole cover rumbled once... twice... thrice... and then popped into the air as All Might leaped out, threw a mighty punch, and splattered the villain all over the walls right as Izumi came her brains out, cementing her newfound perversion as a permanent part of her brain.

Understandably, Izumi passed out.
