Sara's training record at the underground prostitution organization NEO BLACK, which has been ongoing for several months. She endures harsh and rigorous training every day to fulfill the requests of the "perverted" members who seek the ultimate fetish. #1 Urine Training: Receiving urine in a basin or on her body, lapping it up like a dog from the basin and gulping it down! #2 Hard Irimation Sex: Bound tightly with a wrap. Intense throat stimulation during irimation, culminating in multiple orgasms. Even after penis insertion, the irimation hell continues until the end, when she finally swallows the abundant semen. #3 Toy Training: Playing with toys, the irimation hell never ends... #4 Urine Orgy: In the end, the men reveal their desires and engage in a wild sex party! Urine! Urine! Urine! Urine! A sex party where you can drink urine to your heart's content! In the end, she swallows a generous amount of semen.
