It does rip a little. It was flimsy when he got it and he couldn't care less. All he does is twist a bit to make it easier to get off and look brightly up at Mort, propping himself up a little on one elbow to reach for the collar of Mort's jumpsuit. Slightly awkward choice for this specific application, but he's known plenty of mechanics and engineers. Doesn't get in the way so much if you know what you're doing. He kisses Mort again as he unzips, wanting to feel that tongue and the tingle that goes with it again.
