In just ten days, I, the tutor, was completely transformed into a servant by a rebellious girl... GEBB-016

Rebellious and highly sensitive young girls. They want to see men's penises, they want to see semen. They get a new toy—a tutor—and decide to train him into a servant within ten days. They masturbate in the blind spots of textbooks, and force themselves on the tutor's face. The tutor frantically tries to hide his erection. When he's about to ejaculate prematurely, they punish him by masturbating him. They are truly super S girls.
