"True," she said after thinking about it for a minute. "Didn't always happen that way, though." She might be substantially younger than her brothers, but she still remembered some notable times when they had gone at it.
Amy moved off of Thomas, revealing that both were completely clothed and that whatever Theo had heard was entirely innocent. That would teach him to jump to conclusions, he thought ruefully, though he kept his face straight.
"I see," Theo said dryly as Amy's vaunted brain finally caught up with the situation and she blushed pink. He wondered if he was going to have to have some sort of talk with Thomas about Amy, because really, they were both teenagers and boy-girl friendships rarely survived the teens without sex entering into the equation.
He switched his glance to Amy, hiding his amusement at this well. He was going to have to tell Pansy about this just so he could laugh. His sister flushed again, but bravely met his gaze, her chin thrust out in that defiant way of hers. "He wouldn't let me have it--the gift," she hastily corrected herself.
He sighed. "All right then. Don't hurt the presents and please, behave yourselves," he said pointedly. "Remember dinner is in a little while," he said as he turned to leave, before his poker face could fail him and they saw him smile.
