My Cuck Academia: Cuck System in My Hero Academia

Kima Yami thought his life couldn't get any worse. When he died at 15, he was reincarnated into the world of My Hero Academia and had to grow up as a baby. 

Everyone had quirks, and he was about as useful as a fart in a hurricane. "Teleport," they called it—a glorified party trick that let him zip two meters while holding his breath. 

Pathetic. Yet somehow, the universe threw him a bone in the form of Momo Yaoyorozu, the hottest, richest, most fuckable chick in all of Japan.

Momo wasn't just a catch; she was the whole goddamn ocean. That silky black hair that draped down her back, her big brown eyes that always seemed to sparkle like she gave a shit about your problems, and a body sculpted by horny gods—tight waist, wide hips, and tits that could smother a grown man. 

Everyone knew she was the girl every guy jerked off to. And somehow, against all odds, she picked Yami.

To the outside world, they were perfect. Momo, the sweet, loving girlfriend, and Yami, the lucky bastard who landed her. But Yami knew the truth. 

Deep down, Momo wasn't just sweet—she was a closet slut. She had this freaky side she kept bottled up because her snooty-ass family would shit bricks if she acted on it. 

But Yami saw it in the way her breath hitched when he grabbed her ass a little too hard or how her thighs clenched whenever he teased her in public. She wanted to be bad, but she needed a push.

The problem? Yami couldn't be the one to give her that push. With his sad 8-centimeter dick and zero charisma, he knew he wasn't enough. 

Hell, every time they had sex, it was like trying to satisfy a lion with a tuna sandwich. 

She always smiled afterwards, saying how much she loved him, but he could see the frustration in her eyes. She deserved more, and Yami knew it.

The kicker came a week before the U.A. entrance exams. They were at their usual spot, a cosy café downtown. Momo was sitting across from him, her tits practically spilling out of her sweater, sipping on some overpriced coffee. 

She was talking about their future, about how they'd make the perfect hero couple. Yami nodded along, not really listening. His mind was stuck on how lucky he was and how much of a loser he felt like.

Then, out of nowhere, it hit him.

[SYSTEM ACTIVATED: WELCOME, HOST.]

The words rang in his head like an alarm bell, followed by a deep voice that sounded like it belonged to some sleazy game show host.

[Daily Mission: Have Momo Flash her fat tits to someone in public. 

Reward: Increase Teleportation range to 10 meters.

Penalty for failure, reduce penis size to 6 cm]

Yami blinked, his brain scrambling to process the words. Was this a joke? Then the voice returned.

[Reminder: failure to complete missions will result in penalties, starting with a 2-centimeter reduction in penis length.]

"Fuck me sideways," Yami muttered under his breath.

Momo looked up from her cup, concern flickering across her perfect face. "Yami? Are you okay?"

He forced a smile, waving her off. "Yeah, just... thinking."

But his mind was racing. A fucking system? And not just any system—a cuck system. The idea made him want to punch something, but the rewards were no joke. Ten meters of teleportation range? That was actual power, something he could use to stop being a walking disappointment.

The more he thought about it, the more it made sense. Momo loved him—she'd do anything for him. And deep down, he knew this was her chance to let that freaky side out. All he had to do was sell it to her.

"Momo," he started, his voice low and serious. She tilted her head, curiosity replacing concern. "What is it?"

"I... I had a vision." "A vision?" she echoed, setting her cup down.

"Yeah, like, some kind of entity spoke to me. It said we could become stronger—both of us—if we, uh, embraced certain... challenges."

Her brow furrowed. "Challenges? What do you mean?"

"Like... letting go a little. You know, being more open. Doing things we wouldn't normally do." He leaned in, his eyes locking with hers. "It's not just for me, Momo. This could help us both. Imagine becoming even stronger, being unstoppable."

Momo's cheeks turned pink, and Yami saw it—the spark of curiosity, the glimmer of something darker. She was intrigued.

"If this will help you," she murmured, her voice hesitant but eager, "then I'll do it. For us."

Momo slapped some cash on the table and dragged Yami out, her cheeks pink from either the cold or the sheer fucking absurdity of what she was about to do. 

He kept his mouth shut, heart pounding and led her toward a sketchy alley.

They found some poor bastard hunched over, puking his guts out against the wall. The guy looked like he hadn't seen a shower in a week. Perfect target.

"Hey, you!" Momo called out, her voice surprisingly steady for someone about to flash her goddamn tits. The drunk turned around, swaying like a loose hinge, his bleary eyes struggling to focus.

Momo took a deep breath, grabbed the hem of her sweater, and yanked it down, her massive tits bouncing free like they'd been waiting for this moment. The drunk's eyes widened, his face turning beet red as he gawked like a starving dog seeing steak.

Yami's dick was already hard just watching, but he wasn't about to stick around. He grabbed Momo by the ass—because why the fuck not—and teleported them out of there, leaving the drunk stumbling and muttering to himself.

They reappeared in the middle of the main street, Momo panting, her sweater still half-off. "Fuck, let's go," Yami muttered, grabbing her hand and hauling her toward her mansion like they'd just robbed a bank.

By the time they reached her place, both of them were horned up beyond belief. They slammed through the front door, practically tearing each other's clothes off on the stairs.

Yami pushed her against the wall, his hands all over her perfect body, squeezing her tits and ass like a man possessed. Momo kissed him back, desperate and sloppy, her nails digging into his shoulders as she moaned into his mouth.

They barely made it to her bedroom before Yami kicked the door shut behind them, and they fucked for the rest of the day and night.
