Where a lad has a wank, but after the first (orgasm) or cum session he carries on going to achieve multiple rounds of cum. Danger, can become tiring and painful !
i came 4 times in multi-wank last night!

Guy 1: Did you see the porn website I emailed you?
Guy2: No, I couldn't, my mom was home and I had to multi-wank, but I did it when she fell asleep.
