Code: Breaker, Oogami/Sakura, shounen manga didn't cover this
"So this is Sakurakouji-san's room," Ogami said, brushing past her. Navy blue bedspread with white pillowcase, karate and judo belt racks, uniforms clean and folded, volumes of Hajime no Ippo and Fist of the North Star arranged with military precision on her bookshelves. Sakura closed the door behind her, and he sat down at her desk. He was smiling--she didn't like that smile, it meant that he was up to something that she wasn't going to like.
She sat down on her bed and realized that she had never had a boy in her room, or even in her house. If Ogami weren't a murderer and she weren't committed to stopping him (or at least slowing him down), it would be like something out of a shoujo manga, or at least what she thought a shoujo manga would be like. She'd never read one.
"This is Sakurakouji-san's home"--something in the way Ogami said home made the smile disappear from his face, and Sakura thought, I like that look even less. "Home," he repeated.
He stood up from the chair and took off his glove; for some reason, she wasn't afraid. He fell to his knees before her and buried his face in her lap, and she sputtered out, "O-Ogami--"
"I'm cold," he said, and slid his ungloved hand into her skirt. He didn't go any farther than the side of her thigh, though, and they stayed frozen that way for a long moment. She shivered--perhaps trashy shoujo would have prepared her for this. Ogami's fingers inched their way up her thigh, and they weren't cold. When he slid two fingers into her (she had broken her hymen a long time ago but she was tight and not nearly wet enough for it to be comfortable), it didn't matter that he was lying because he yanked her underwear off and buried his face between her legs.
Sakura fisted a hand in her blankets and covered her mouth with the other. Even if there was no one home she wouldn't give him the satisfaction of making her cry out. The hand inside of her had killed so many people; the mouth on her had announced their deaths, and she couldn't forget that, let alone forgive him for it--no matter how vulnerable he seemed--but when she came, twisting and muffling her shouts with the mattress and he slid up her body and kissed her, pulling his cock out of his pants, she almost did decided that maybe she should help him get warm again.
