cumming for 5 min would be great but the down side would be the fact that you cant do anything else durning that time so quickies would be a pain in the ass
Neither is a great option. If you fuck for 5 mins that's too short, and if you come for 5 mins that may be too long. Still for argument's sake I rather fuck a nice tight & wet pussy for 5 mins.
Given the choice.....fuck for five minutes.......a climax lasting five minutes would, I think, be nearly unbearable. I'm trying to imagine it, and I can't. I'm pretty sure there would deaths surrounding this if it were possible. They say your mind goes completely blank when you are cumming......five minutes is a looooong time to NOT think........
