I got this erection exclusively by hitting my balls. I did not stroke my penis at all. I decided to go all the way and record a Ballbusting orgasm in my bathtub. I prefer not to end my Ballbusting sessions with an orgasm and since this occasion I have learned how to control and prevent an orgasm. When I bust my balls I'm no expert but I'm pretty sure all the fluid from my prostate flows back into my bladder because when I urinate in the middle of a session the urine has a ton of foamy bubbles. #Ballbusting #Cumshot #Masterbation #SelfBallbusting
