Matt was, yet again, caught up in the kiss she pulled him into. He should've never agreed to this. If he'd had the upper hand at the start, he was definitely losing it.
After several long moments of kissing her desperately, he ripped his mouth from hers again. "If you're toes are curled... and I'm certain that they are," he drawled breathlessly, "I've held up my end of the bet and it's time for you to hold up yours."
It was literally painful to say that but he knew that Joseph wouldn't appreciate it if he screwed his little sister. He had to be the better man, here... regardless of what his body wanted.
