Mitsuki Nagisa picks up a submissive adult man on the street, takes him to a hotel, and keeps him as a cock slave for 24 hours. She begins with nipple torture and a handjob for his first ejaculation, then drains a second load by blowjob before raw sex and a third creampie. More handjobs and vibrator stimulation follow in a relentless cum-milking marathon. He is forced to ejaculate nine times, including a prostate-driven release during strap-on penetration and a no-stroking orgasm triggered solely through nipple torment.
