Well, first she screams...

"AAAHHH!!" Ochaco bolted upright in her bed and threw a pillow at the glowing boy on reflex. The pillow passed through him as if he wasn't even there. Ochaco didn't even process that as she threw her other pillow through him. Then she threw her figure of Thirteen.

AH! It'll break! Everything goes through him and it's a rare collectible! What was I think - Those thoughts were cut off as the floating boy caught the figurine and gently set it down on the dresser.

"Please calm down, Mistress," he said, a soothing pitch to his voice. "I know this is a bit of a shock, but I promise I'm not here to hurt you." Bows again. "I'm here to serve you."

"Serve...?" She became aware of her state in front of him and closed her laptop to hide her porn, then gathering up her pillows and covering herself with one of them and her blankets. "Okay...start talking before I call the cops."

The boy nodded. "Yes Mistress. How to start?" He put his hand to his chin in thought. "Well...introductions. My name is Izuku. And I'm your sex genie. You found my lamp - er, cock - and claimed it. So now I'm yours." He smiled, proud of his explanation. But when he saw her continued confusion his smile dropped. "You need a little more, don't you?"

"Um...y-yeah. Sorry." Ochaco couldn't stop looking him up and down. He looked so soft, not the muscular kind of boys she saw during the exams. Like he was designed to be overpowered. Dominated. Her cheeks reddened. I hope genies can't read minds. "S-So...let's say I believe you. What does this mean for us?"

"Well, it means I belong to you now, and that you can use my magic to fulfill your every desire!" Izuku stated proudly. "...Within reason, that is. I am a sex genie, after all, so all my wishes have to be somewhat sexual in nature, or used for physical pleasure in some way."

"Why a s-sex genie?" Ochaco asked. "Are there other kinds?"

"Oh, yeah! There's Morality genies, who are trained to twist wishes in order to help their masters learn lessons and become better people. They're the ones most commonly impersonated by - ugh! Freelancers." Izuku folded his arms and pouted at the word. Whatever a Freelance genie was, he clearly didn't like them.

"But I went to Genie Academy to be able to provide pleasure to those who really need it. That's why my lamp appeared in a hero school. Anyone going there was destined to have a hard life. You all need a little selfish hedonism to unwind after a hard day." His cheeks turned a somewhat darker shade of blue - was that his version of blushing - as he looked at her. "And you clearly needed to unwind, Mistress."

Ochaco blushed back, though there was something he said that got her attention. "You went to an academy? Like, you went to school to become a genie? I thought most genies were slaves to their lamps."

"Yes, Mistress. I went to a very special academy. It took 300 years to get my sex genie license. Look for yourself!"

He snapped his fingers and a plastic card appeared in Ochaco's hand. It showed the glowing blue boy beaming in a photo, information like his name (Izuku) the type of genie he was (sex genie) his age (1918) and a seal made to look like a genie's lamp as an official credential.

"So you see, Mistress, this is like a job for me. My dream job!" Izuku poked his fingers together. "And you're actually my first ever Mistress, so I want to do a good job too. If you wish me away, that's like being fired. You're allowed to do that, Mistress, but please - give me a chance."
