Barry was not above fighting dirty when it came to winning an argument. Especially not an argument he felt strongly about. And it certainly didn't hurt that winning involved the fringe benefit of instigating some very enjoyable activities with his boyfriend. As far as he was concerned, there were no downsides to this particular situation. This kind of thinking probably meant he was a bad superhero, but he was taking a vacation from that anyway, so it was fine.
His own hands were working on undoing Len's pants before the older man was even finished speaking, so it was pretty safe to say that he was on board with the plan. Still, he probably needed to answer the question. Which might have been easier if Len hadn't been doing what he was doing. As it was, his first attempt at responding was cut off with a low moan, his mouth dropping open and his eyes slipping closed as they moved against each other.
"I say," he said finally, "that you are talking way too much and there are better uses for that mouth." He punctuated the words by dragging Len into a rough kiss, focusing on that and the way their hips continued to move together. God, arguments were the best.
