Iness - Hard Flexing Orgasm

Description: Someone asked me: how hard can you flex your muscles? do you think you can pump them up and grow them just by flexing really hard? i think he will find the answer after watching this video... i didn't think my biceps could get that far! i didn't think squeezing that hard would pop out my 6 pack abs! i really didn't think i could generate so much muscle pressure to give myself an orgasm!
