After his girlfriend orders him not to masturbate during her five-day trip, an injury lands him in the hospital. Her friend, nurse Kuno, starts playing with his cock while insisting it is not cheating if he does not ejaculate. She edges him relentlessly every day, then locks him in a chastity device when he accidentally erupts. Using her pale breasts and huge ass, she repeatedly builds him up and drains him, ultimately extracting 11 loads during five days of maddening orgasm control.
