This is a scenario titled "10-minute challenge to make a famous university student orgasm using only the mouth." If unsuccessful within the time limit, a penalty game involving other body parts must be played. The challenger Yuka attempts to make the male orgasm using only her mouth but fails, so she exposes her breasts and allows him to touch them. Time runs out, triggering a rescue mode where she has 5 minutes to make another man ejaculate. However, Yuka fails again, resulting in the penalty game—unprotected sex with internal ejaculation.
