Izuku has a powerful set of quirks.
The first, transfer, allows him to copy the quirks of women he fucks.
The second massive cock: he gains a gigantic 12 inch long 6 inch thick cock.
The third: pheromone. Deku has an aura that attracts women to him.
The forth, Love code: the women he fucks and attracts then fall in love with him loyally.
Energy transfer: he can give and take strength from the women in his harem.
Immortality gene: he effectively doesn't age anymore, and the women he takes, won't age either.
Genderbend: he can change a male to a female. (Duh, lol)
Enhanced stamina:deku can last for hours during sex, which is a blessing and a curse sometimes.
Takes place after the entrance exams.
Deku had just gotten out of the shower, his muscle's flexing slightly as the water dripped off his back, suddenly momo walked in the shower causing momo to blush slightly and deku to gasp.
"Shit! Sorry, I must have had the shower off long enough for someone to think it was free!" Deku yelled, that wasn't why momo was blushing, she was looking down, as he didn't put his clothes on yet.
Instantly deku tried to cover himself, of course he was way too big, so he failed miserably.
"You're really big…" momo said in shock, he was flaccid yet still 8 inches. Momo couldn't control herself, she quickly gripped deku's shoulders and pushed him against the ground causing him to gasp.
"I can't stop myself, I need you midoriya…" momo begged, midoriya watched as momo got on her knees for him, she was fucking beautiful. Was he really gonna pass up this opportunity? Is this a part of one for all?
Momo wrapped her hands around his massive shaft and began jerking his cock off slowly, midoriya clenched an eye moaning in pleasure.
Midoriya's cock slowly rose, 9, 10, 11 finally stopping at 12, it was so huge, it left momo's mouth a gape.
"Suck it" Deku ordered, momo's eyed glew green briefly as she was ordered.
"Yes daddy…"Momo replied, she opened her mouth and slid his cock into her throat gagging slightly, deku moaned in pleasure and gripped her head forcing her down harder.
'I've never actually used my quirk on someone, she's so fucking good at this…' deku moaned his eyes rolling slightly, she was a Fucking natural, she could take his 12 inches all the way. With some struggling and slop of course.
He clenched her hair tightly beginning to thrust in and out of her throat, thick layers of spit covering his cock "mmmng, tap me if you can't breath." Midoriya breathed out shaking his cock around her throat.
Suddenly, with another heave she puked all over his cock, his balls and thighs getting drenched in the disgusting puke, momo tried to tap out, but deku didn't pull back, instead he roared getting closer to blowing.
"Hold it, I'm gonna cum soon!" Deku moaned fucking her throat harder, digging more and more puke out of her throat causing her throat to burn, momo's eyes glew green again due to deku ordering her to stay still.
Midoriya moaned out loudly beginning to spurt strand after strand of cum deep down her throat, cum spurting out of her nose as he came.
"Guzzle it down!" Once again, momo's eyes glew green as she swallowed his gunky thick semen. He pulled away slowly spurting cum on her face panting deeply as his cock dripped with puke.
"Sorry, It felt too good" deku said, momo puked one more time all over the floor before taking in deep breaths.
"It's ok daddy! I can take anything if it makes you happy!" Momo said.
'This can't be one for all, I don't remember all might being able to do this to women, man My dick is all covered in puke now and I just got out the shower, I guess I can shower again though' midoriya thought.
Once again, her eyes glew green, and she quickly began licking all over his giant cock shocking midoriya, did she read his mind? Or did his desires beam into her head?
Like a good girl momo completely cleaned off his cock before grabbing his hand suddenly leading him off to her dorm completely naked.
Momo's ass was bouncing back and forth as were her breasts, momo closed the door behind her beginning to rub his ripped body frame. "So strong." Momo moaned.
"Daddy, I need you inside me, I want you to wreck me" momo begged, bending over. Her eyes flashing from green to its normal color as if showing that he was close to taming her.
Midoriya stared down hercunt with. A huge blush on his face, he gripped her hips and forced himself deep into her pussy with a grunt clenching his eyes.
He thrusted back and forth in and out of his cock panting deeply, momo's ass bounced back and forth while being wrecked, she moaned out loudly her eyes rolling to her head.
"Whats that noise? Someone in the dorms has a guy over?" Some of the women asked.
Deku couldn't help but smirk, he was so lucky to be destroying her cunt like this.
The bed began shaking as he thrusted in and out of her pussy, he grunted forcing himself into her cervix and into her womb causing momo to scream even louder.
"Ahhhh!" She moaned out like a bitch in heat, her eyes rolling and her tongue hanging with a stupid smile on her face.
"I'm gonna cum daddy!" Momo screamed.
"Cum for me then whore!" Midoriya yelled, suddenly both of them came, midoriya filled her with his gross thick spunk. Momo screamed louder with him screaming his name before dropping to the bed passed out, not before her eyes finally became a perminant green, deku panted deeply pulling out of her cunt spurting on her back.
"Crap…" he panted.
Deku had to take momo to the hospital the next day, examined the now green eyed momo in confusion.
"It seems you have a secret quirk we didn't know of" the doctor said with a smile. "It's a very rare quirk."
"Someone has had it before?" deku asked.
"Indeed. Much like how ono for all can be transfered, your father possesed the quirk before you were born" the doctor said causing his eyes to widen.
"Its powerful, and un fightable, it allows for women to fall inlove with you, not only that, but it comes with other quirks, you have an aura around you that you can amplify or weaken to attract women, in fact its hard for me to be professional about this right now…"the doctor said crossing her legs.
Deku was shocked, he didn't even understand this "Shit, sorry I guess I have to learn to control it?" He said.
"Indeed, but theres more, you can also take the quirks of the women you tame, and even amplify or weaken there powers, not only that...but you are effectivly immortal. Of course combat can kill you which is how your father died.
"Wh….what?!" Deku said in shock.
"Indeed, toxins don't affect you, and you or your women won't age anylonger, another thing, a serious draw back" the dr. Warned.
Deku suddenly got serious, ignoring the craziness of the situation "what is it"
"If your women are away from you,they can go insane depending on for how long, and even die…." The dr stated "you must be careful on who you activate this quirk on, because momo is currently completely dependent on you now, she is yours" the dr. stated.
"Understood" deku nodded.
Deku finnally arrived back to the dorms with momo and she was quick to tell everyone about deku.
"Is he really 12 inches?" Uraraka asked in surprised.
"Almost 13! And he's super thick too!" Momo said to the girls with a smirk.
"No way" they all said looking at eachother in shock.
