Here’s a video of a guy, a little on the heavy side with stretch marks, fucking the shit out of his fleshlight that’s positioned between his mattress and box spring. He clearly has that thing wedged in there good because he pounds away on his fake pussy and it doesn’t budge. Though you don’t see him pullout with cum dripping off his dick, I’m pretty sure his change in striking at the end signaled him cumming inside his fleshlight.
