Waking after a long night

Ochaco mumbled and rolled over, her cheek smooshing into the gentle glow of a giant, blue breast. As she awoke, she was initially startled by what greeted her, before remembering the night before.

Before they went to sleep (or at least Ochaco went to sleep - she wasn't sure if her genie needed sleep), she'd decided to test the limits of his shape-changing abilities. It was quickly made apparent there weren't any, but that didn't stop her from playing around. Izuku was currently 15 feet tall, curled in on himself to fit in her tiny bedroom. He had two pairs of breasts each the size of a beanbag chair with one pair below the other. He had four arms all wrapped around her in a sleepy hug. His ears had been replaced with fox ears and he had nine bushy kitsune tails coming out from above his jiggly dump-truck ass. His balls were also massive beanbags that her legs rested on while his shaft was easily as tall as Ochaco herself.

She'd went out of her way to make him as ridiculous as possible just for fun, and while she couldn't fuck Izuku in this absurd form, she did find it was very comfy to sleep with.

Izuku smiled down at her. "Are you awake now, Mistress?"

"Mm~ yeah. Feeling really well-rested, too," She got up off his huge breasts and balls and stretched. "I can't tell if it's from using you as my bed or all the times we came last night."

"I'll take it as a compliment either way, Mistress," the genie chuckled.

"Um...change back to your normal self. I'm not gonna be able to do anything with you filling the room like that."

With a simple nod Izuku morphed back to his femboy self, all in the span of a single blink. Ochaco whistled to herself, impressed and a little turned on. With Izuku around, she expected to be "a little turned on" basically all the time now.

"So if I remember right before we...got intimate," Ochaco began. She went to her discarded pajamas and started putting them on as she spoke. "Mom and Dad came home and mentioned going to the beach. They'll probably have a fuzzy memory of last night. We could probably get away with not troubling them and they won't even notice."

"You don't want to go to the beach, Mistress?"

Her brow furrowed in a pout. "I do, but I also don't want them dragging themselves around after a long night at the site. They need rest."

"Um, Mistress..." Izuku grinned sheepishly and floated beside her. "You can make them well rested with the right words."

"It has to be sexual, though. And cumming makes people more tired, not more energized," she replied.

"You could make it the opposite."

"Oh yeah." Ochaco blinked as she remembered again the full extent of her genie's powers. "Okay, um...I wish my mom and dad would cum really hard in their sleep, and that this orgasm would make them refreshed as if they got 12 hours of sleep. Oh, and I wish they didn't find it weird."

Izuku snapped his fingers. The sound of tandem moaning came from through the walls and Ochaco blushed. She hadn't thought of her parents in a sexual light before, but now...

"O-Okay, that was pretty hot..." Ochaco finished getting dressed in her pajamas and held out the hem of her flannel pants. "Uh, hop in."

Izuku snickered, flew up, and dived into Ochaco's cock. She moaned, and when she looked down her eyes nearly bugged out of her head. Her cock was monstrous! Izuku's length plus her length - a 19-inch long, 2.5-inch around beast! Her balls looked like a pair of grapefruits!

"HOLY SHIT!"

What's wrong, Mistress? Izuku asked in her mind.

"I'm...HUGE! Why is it so fucking huge?!" Ochaco willed her cock away. Instead, it just shrunk to match Izuku's original dick. She willed hers back, and the insane size returned. "I can't get rid of the cock completely?"

Well you can, Mistress, but only your cock. My cock is my lamp, remember? Unless you don't want me attached it's not going anywhere. Izuku explained.

"So no matter what I'm going to have this huge, noticeable bulge?" Ochaco looked down. Even with just Izuku's cock, this bulge was going to get a lot of stares.

You could make it so no one notices it, Mistress, Izuku suggested.
