Was prone humping my couch armrest yesterday and couldn't get off. Almost but I kept losing it at the last minute. I finally stopped humping was just resting in position and was about to give up in frustration and hit the shower when suddenly the pressure started, if you know what I mean, and I spontaneously came super hard. One of my biggest cums tbh. What happened? Is this progress?
