She's in heat, would be mean not to!

"Okay, let's get a bit more fun in before I head out," Izuku remarked, getting up. Ochaco mewled in protest as his dick moved away from her mouth, and she crawled around on the floor, reaching up and pawing at his thigh, meowing pleadingly.

Setsuna giggled at the sight. "Yeah, you better, she really wants more sex. She's a horny little kitty," she added, grinning teasingly at Ochaco, not that Ochaco understood she was being teased at the moment.

Izuku then moved around to get behind Ochaco, and knelt. Her expression brightened, and she immediately set herself in place, separating her thighs some more, showing Izuku her slick pussy as she looked back pleadingly. He placed his cock at her entrance, and wasted no time, plunging right into her heat. "Nyah!" she mewled happily as he buried himself to the base.

He grabbed her tail, and began thrusting back and forth into her depths, moaning. He never could get tired of fucking Ochaco from behind while she was in Neko form like this. Her pussy was always so accomodating, his cock a welcome guest into her entrance. "Been a bit too long since I took you from behind like this..." he moaned as he kept going, her vaginal walls embracing his shaft.

"Nyah?" Ochaco meowed in both pleasure, and curiosity, not currently able to comprehend his speech at the moment. He simply smiled and pet her ass as she thrust her hips back into his pelvis.

He chuckled and lightly tugged her tail. "Don't worry about it," he said knowing she didn't understand the words, but had a disarming tone to cause her to mentally shrug it off.

She relaxed, simply focusing on caressing his manhood with her vaginal walls, purring in contentment, mewing with every time his hips smacked into her ass. "Nyah, nyah..." she moaned, scratching at the carpet.

Izuku pounded into her, grunting as his climax built. "Ungh!" he grunted, before his seed burst into her waiting pussy.

"NYAH!" she yowled in ecstatic bliss as she came hard, her tongue lolling out. Spurt after spurt flowed into her before his erection was spent, and he pulled out, letting her sink to the floor, purring in pure contentment.
