Give in and try to get Mineta back in the game

Izumi smiled and liked some of the cum from her fingers, locking eyes with Mineta as she did. It was bitter and kind of gross, but it was clearly having an effect on the boy so she kept going. It got less gross as she went, the effect she was having on Mineta outweighing her initial feelings on the act. Plus, the taste wasn't that bad once she gave it a chance. It was actually kind of nice in a weird way.

Once her hand was pretty clean, she took his hand and pulled him over to the bed and sat him down. She sank to the floor and crawled between his legs. She rested her hands on his thighs, carefully positioned so the coin was touching both of them. "Okay stud, how about we get you prepped for round two and you can show me what this big cock of yours can do?"

"B-big?" Mineta asked.

"If I have to sell it, you should too," Izumi said, winking. She leaned in and took his dick into her mouth, swirling her tongue around the head of the flaccid tool and sucking on it, trying to bring it to hardness.

Mineta seemed to pick up on what she was sating, if not the reason for it. "Y-yeah, suck my big cock. You love it, don't you. You're the biggest slut in our class."

"Mmm," Izumi moaned, looking up at him for a moment before focusing back on her task. She heard him continue, telling her to suck on his huge dick, to use her slutty mouth and show how much she loved cock. She heard the slight shift in his voice, it becoming deeper, before she felt any changes. His dick started getting bigger a few moments after his voice started dropping. It grew from 4 to 5 inches, then 6, and all the way up to 10. She kept waiting for the moment that she'd struggle to continue sucking him off but it never came. She seemed to be adjusting just as quickly as he was.

Finally, he reached down to her chin and pushed her back. His dick came free with a wet plop and she looked up as he stood, making her stand along with him. He was tall now, taller than her by about half a foot. He was more muscular too. He seemed confused for a moment, then shook it off. "On the bed."

She giddily followed his instruction, climbing on with her ass faced toward him, staying on her hands and knees. She spread her legs apart a little and looked over her shoulder at him. He wasted no time in lining up and plunging into her. He didn't have the same issue he had the first time. Now, he was truly a stud. He fucked her to orgasm after orgasm for the better part of an hour. They changed positions every few minutes. Doggy style, her on her back with legs high in the air, him holding her against the wall, her riding him. Finally, with her on her back and him standing, he pulled out and blew a massive load all over her stomach and tits. One blast of cum even managed to shoot right between her tits and land on her face. He let go of her legs and they fell to the floor, then he joined her on the bed. They spent a few minutes catching their breath, neither mentioning the smell of sweat and sex that permeated the room.

"I haven't changed back yet," Izumi said.

"Yeah..."

"Guess we'll... have to try again?"

Mineta looked at her, grinned, and rolled on top of her, his tongue working it's way into her mouth. She wrapped her legs around him, enjoying the feeling of his cock hardening against her stomach and waiting for the moment that it would plunge into her again.
