A standing 69!

"So, Master, how shall we play this?" Ochaco asked as the door closed behind them, reaching down, and pinching the strings of her bikini bottoms, pulling them, and letting the garment drop to the floor.

Izuku stared for a moment, before sliding his own trunks down. "How about using your Quirk and floating upside down? We can do a 69 like that..." he told her, stroking his member to full erection as he spoke.

"I like the way you think!" Ochaco grinned as she applied Zero Gravity to herself. Izuku walked over to her as she floated, and manipulated her midair body to flip her upside down, and she quickly wrapped her legs around his head, her pussy right in front of his mouth. He didn't waste any time, immediately starting to lick her pussy.

"Mmmnh," he moaned as his tongue glided over her delicate petals.

She returned the moan as she gripped his thighs to anchor her upper body in place, and began to lick along his length. She briefly considered taking Neko form again, but decided against it, wanting to instead focus on the novelty of using her Quirk again. Adding the Neko form to every experience might dilute the fun. She also didn't want to become fully reliant on it to feel and give pleasure. She took his shaft into her mouth, and began bobbing her head on it.

Izuku gave another moan, before sliding his tongue right into her pussy. He proceeded to wriggle it around skillfully, knowing the sweet, sensitive spots in her by heart. She shivered as she continued to bob her head frantically. Izuku had really gotten good at that!

"Is the blood rushing to your head at all?" Izuku paused his licks for a moment to ask, before returning to it.

She pulled off his cock, and shook her head with a grin. "Nope. Zero Gravity, remember? And while the blood tends to go up regardless in such circumstances, Momo's magic took care of that among the other issues," she explained, before once again lovingly embracing his cock with her mouth, and sucking like a vacuum cleaner.

They kept this up for several minutes, before Ochaco spasmed and moaned around the dick in her mouth, an orgasm rippling through her body, and her mouth providing Izuku's pulsing member with oh so very pleasant vibrations.

He followed suit, grunting as his manhood filled her oral cavity with his delicious seed once more. She gulped greedily at it, before pulling off. "Oh, I never tire of drinking you, Master," she crooned.

Izuku chuckled as he helped set her down so she could release her Quirk. They gazed into each other's eyes for several moments, just taking a moment to bask in each other's company.
