A very short clip we did for a very nice story - Cum or die.
Unfortunately the result - the Male version - wasn't very satisfying for us, errrm, in a sense of "not being in the story line very well". ;-)

He is strapped down to a gyn chair, his neck is connected via a rope with handcuffs. The rope is running at the back of the chair, when he pulls at the cuffs he is effectively choking himself. A latex sheet is wrapped around his head and he has to cum in the time (and air) that is left in his lungs.

As being mentioned, the result wasn't perfect and we had to cut it down. It's now edited in kinda scary way…
Perhaps you'll like it, nevertheless! :-)
