Well, in this case the title says it all. Yes this dude sticks his dick up his own ass and and fucks himself until he cums. So I would definitely do this if I could (I can’t!). I think it would be like being in the middle of a 3-way dude fuck. And the dude behind you drops a load in your butt at the exact same moment you drop your load into the butt of the guy in front of you.
