Medical experiment Repeated handjob

Description: In this medical experiment i shall attempt to masturbate my patient twice in a row and see where it gets us. it was a custom request and worth tying, ultimately, i wanted to make him orgasm again and again but neither of us was very optimistic. for the sake of transparency i shall add: the original was even longer, but i have reduced it by about 40 minutes, the experiment was rather tiering and i don’t recommend trying it at home.
