A private training session from the staff of "Tuning Club"! "Kana," whose masochistic desires were reawakened in the last training session, follows staff instructions to remove her underwear and head into the room. By the time she arrives, she's already completely ready. This time, through forced masturbation, she transforms into someone unable to stop until reaching climax. Masturbating under observation further stimulates and deeply draws out Kana's masochistic desires. Will she finally achieve the orgasm she so desperately craves?
