"Please, you don't have the balls!"

"I've got plenty of balls, thank you very much, not that you'd ever get to see them." Kokichi said with a smirk.

"There is no way you could just walk up and slap someone, even for a little gremlin like you." Miu said with a sneer. She wasn't quite sure how it had been brought up, but the topic of slapping had emerged, and Kokichi claimed he could easily slap someone, to which Miu, of course, challenged him on that.

"I totally could! I could slap you right now if I wanted!" He said.

"As if! And even if you did, I doubt I'd even feel anything with how small your hands are, probably matches your tiny dick, huh?!" Miu said with a cackle to herself. Kokichi simply rolled his eyes.

"Really? That's the insult you're going with?" He asked.

"Well duh! It's obvious isn't it? Tiny body, tiny cock! Easy!" Miu said with another laugh. "But either way, good luck on the whole slapping thing!" She turned to walk away, and got a few steps before she felt something. A very, very hard smack to her ass. One so hard it made her ass sting, and her body bend as a noise escaped her lips that sounded like a shriek and a moan. It was quick and efficient and once it was done, she turned to see Kokichi winking at her as he dramatically blew on his hand, and started walking away.

"Wh-what the…fuck?!" Miu said, and quickly rushed off, her face red.

Over the next few days, every time Kokichi saw Miu, he would smack her ass. Sometimes it was just a normal slap, but sometimes it was a slap so hard it nearly made her fall over. Despite having made his point, he became relentless in proving her wrong over and over. And the worst part was…she was starting to like it.

But it only escalated from there.

At one point, Kokichi grabbed her skirt, pulled it up, and smacked her ass. The sound was devastatingly amazing as her cheeks rippled slightly. She turned around, red-faced as she grabbed at her ass, only to see the gremlin running away as he cackled. Her lips quivered and her legs trembled. What annoyed her was…she was wet.

And that night she masturbated to it.

The next day, Kokichi peeked around the corner to find Miu standing around, looking like she was fiddling with something. The boy giggled to himself as he creeped towards her, staying out of her sight as he slowly grabbed her skirt, and in one single motion, lifted it up and slapped.

Only this time, he felt bare skin.

She wasn't wearing any panties, and he smacked her ass directly as Miu moaned. Kokichi stood dumbfounded for a moment before she turned around and tackled him to the floor, pressing her body against his own as he felt her breasts against his chest.

"FUCK YOU FOR MAKING ME FEEL GOOD!" She cried as she began to tear at his clothes.

"HEY!" He cried, only to freeze as she shoved her hand inside his pants and grabbed his cock, and then shuddered as she began to stroke it. His resistance faltered as she seemingly expertly stroked him, and before long, he came right there in his pants, panting heavily as she stared at him.

"Want more~?" She asked, though her face was also flushed, giving away how she was also embarrassed. He gave it some contemplation, then shakily nodded, to which she pulled him to his feet, and the two started moving to the dorms.

And Miu had him continue to slap her ass along the way.
