I learned to do this on long car rides as a teenager with my family. I’d shut my eyes and pretend to be sleeping, but actually I would be playing out all kinds of sexy scenarios in my mind. I’d go for a long time, pulsing my cock in my pants, until finally I would shoot a hot load. Hands free.
I’ve also done this on a massage table when I turned over after the first half of the massage session. I’d be so worked up from lying on my stomach and the glute and hamstring massage, it only took a few strokes of my chest and thighs (hands sometimes grazing my hard cock) for me to explode all over my chest. The therapist is always a male - so he gets it - and I always announced it when I was cumming. The best part is that I usually got a hand to help milk it all out in the end.
. I love to cum hands free. Edging is the key.
