Odd Couple

A/N - Slight sexual interaction between a 17 year old and a 15 year old. Nothing explicit.

Yugi had always assumed that he would be well into his adulthood before he kissed a girl. It wasn't for a lack of desire, but he realized that his late bloom into puberty had done nothing to appeal him to women, except in the most childish ways. It was sheer luck that anyone had been able to look past his physical traits enough to even call him their boyfriend – more so that it was Kokoro. Fully developed, and two years his senior, with the ability to choose any boy from their school, and she had picked him.

He had expected that she would want to wait, that she wasn't interested in the physical aspects of a relationship until after he stood at least as tall as her. But he was wrong there, too. It might have bothered him, that she could be attracted to someone who had only just begun to grow body hair, if the few men she dated previously hadn't been in quite the opposite position – and if she hadn't seemed to thrilled to find a thin plain of hair on his chest.

“Congratulations.” She cooed from above him. “Oh, Yugi-kun, you're becoming a man.”

He tried not to get offended. It was a compliment, of sorts. Jou and Honda had seen fit to make a scene about it earlier in the day, which had embarrassed him far more as nearly every male in his grade – and his gym teacher – had been witness to it. Of course, it was also their fault she had demanded to see in the first place. They – mostly Jou – had loudly joked about Yugi finally growing into a man on their way home.

She continued to pet the soft, almost invisible hairs for a moment, oblivious to his discomfort. Her physical boundaries were much more lax than his own, and she seemed to think nothing of it as she sat astride his stomach and stroked his chest like a cat.

She grinned the kind of grin she reserved for only two scenarios – when she had just done something that would win her a game, or when she was about to say or do something obscene. The last time he saw it had been his birthday, but they had only gone so far as the first few buttons on her blouse – though that may have been due to the untimely arrival of his friends.

“I'm impressed. Practically came in overnight.” She shifted off of him, and he thought perhaps the embarrassing conversation was finally over, but her fingertips suddenly slid into the waist band of his uniform pants. “I wonder if you've got hair anywhere else.”

“Hey!” He shot upright and grabbed at her arm. Kokoro was much stronger than him – something he liked to pretend was because of her athleticism – and her fingers remained exactly where she put them, curled around the waistband of his pants and underwear. He pulled on her arm, but she refused to budge.

“What's wrong?”

“You don't need to-.” He couldn't say the words, and they mashed together into a weird, incomprehensible noise. In response, she wriggled her fingers a little deeper beneath the fabric. “Stop!”

“Why?”

Because he had seen more male anatomy than he ever needed to in the locker room after gym class. The response was on the tip of his tongue, but his pride refused to let the words out. No man could ever admit that he was inadequate. It went against everything in his nature, to tell her that not only did he not measure up to boys his own age, but that her previous lover put him to shame.

Before he could think of what to say, she seemed to come to an answer herself – and shoved her hand fully into his pants. He cried out in both surprise and panic, and nearly leaped backward before he realized what a mistake it would be while still solidly in her grasp. He could do nothing but sit there, hands uselessly wrapped around Kokoro's arm as she took hold of a place previously untouched by anyone but himself.

Her exploration was not sensual, but his body responded regardless, as her hand slipped down to examine the thin layer of hair that refused to bloom farther. Though his body warmed, his head remained cold with terror as she moved back up to investigate the part of him that he feared was so sub-par. She seemed surprised to find that it had grown, and gave an experimental tug that forced a desperate, terrified groan from his mouth.

“Yugi-kun,” He braced himself for the inevitable – the we can't be together, the you're so pathetic. “I'm impressed!”

“W-what?”

He dared to glance up at her. She hadn't removed, or stopped the motion of, her hand, which made the task incredibly difficult, but he managed to settle his eyes on her face. A pleased grin had broken out over her features.

“Yep! This is good. Your boys are full size, which means you're due for a growth spurt any time. And I don't just mean you'll get taller.” She finally, finally, pulled her hand out of his pants, but at that point he wanted her there more than he wanted her gone. “And you're already this size, too. I think congratulations are in order!”

“Y-you're insane!” He shouted, as he was once against shoved back onto his bed. “I didn't realize you were such a pervert.”

“Oh, hush.”

She straddled him, her weight almost unpleasant on his hips as she worked the buttons of her blouse. The swell of her breast came into view mere moments before the lace of her bra, a sight that knocked any protests from his head. With little regard for the fact that his door was not locked and his grandfather was home – though in the shop, which he couldn't just walk away from – she threw her shirt into the distance.

“Let's celebrate.”
