Darcy didn't want to stop, even though it was going to be inevitable that he would be the one to stop first. But he didn't want to; he wanted to keep moving, and keep his mind focused only on what way to move next. He wanted to get every last bit of tension worked out of his system.
And he actually was enjoying himself, as well. So much so that he found himself laughing breathlessly at some of Miguel's little trick moves. He had absolutely no idea how long they'd been playing about for, and he had only managed to lightly graze his suit once in that whole time. Not that it mattered, that had never really been the point.
Eventually, after pushing it for a little longer than he really should have, and having ignored the tell-tale signs that his back was unhappy with him, Darcy had to admit defeat. He stopped moving before he actually said anything, moving his shoulders and stretching his spine with a slight wince. It would be fine after some rest.
"A break, time for a break..." he confirmed to his friend.
