Ok, I’ll admit even I was cynical about the possibility of a male HFO (the accepted abbreviation for a Hands Free Orgasm) until it happened to me. Several times.
The first time I even looked into coming without using your hands or touching yourself was when I had a small tear on my ‘banjo string’ (frenulum for all you medical types). I was desperately horny but didn’t want to risk any kind of extra friction lest I end up shooting blood instead of my load. Lube was out of the question as it stung but I really wanted to get off.
