When I was really young I got into an exercise kick and decided to do chin-ups on the top of the door frame to my bedroom. I have always loved being naked and was doing my chin-ups nude. When I reached the last possible chin-up that I could possibly do I brought my knees up towards my chest to try and help me reach the top and when I let them go back down my thighs brushed around and down my cock.
Well, this amazing feeling hit me and I did the whole thing again which wasn't difficult because this new energy came over me and I did about three more in quick succession. I think I was too young to squirt anything but I definitely had a great orgasm. So every night I would do my chin-ups and also started making gooey stuff spew along my thighs. At the end of my chin-ups I would be hanging exhausted from my door frame with my dick sandwiched between my thighs and ooze running down from it.
One night I thought, 'why not omit the chin-up part and just lay in bed and push my now easily hard cock down between my thighs and after gripping around it let it spring back up with the thighs still around it?' This worked superbly and resulted in my chin-up sessions ending in favour of thigh squishing on my bed to great orgasms. I was lucky to have found out about masturbation by accident before I found out about guilt, so I have no such feelings about jerking-off. Too bad I didn't stay with the chin-ups, because I would have a great deal more muscle development now. I showed my thigh masturbation technique to a girl friend many years later and she said that it looked very sensual to watch. My cock has this downward curve to it that I wonder if it is because of my thighs holding onto it before it popped up from between them. Also, because I don't have any guilt about masturbation, I am very interested in having women see me masturbate for them.
