In #01 Orgasm Endurance Gangbang Sex, Chiharu is teased and pleasured in various ways while being fucked during a gangbang. She finally takes a load all the way down her throat before moving onto the next challenge. In #02 Piss Drinking Challenge, she must drink every drop of urine poured over her body like a thirsty dog lapping up water. The final challenge, #03 Sadistic Irrumatio Urine Gangbang, finds her hair pulled back as she's roughly masturbated until she can't take anymore. As they enter a wild orgy, the men fill her mouth with their cum, which she has to swallow without spilling a drop... or else! Note that the contents may vary depending on the recording method used.
