Minami Kyo is a current female teacher. Her biggest secret is her shockingly huge K-cup breasts that cannot be hidden even under her clothes. Although she is unaware of it, these breasts have been captivating the attention of her students and colleagues, and now they are finally revealed in her AV debut. In stark contrast to her strict appearance on the podium, the sight of her moaning on the bed, her huge breasts shaking, is the very embodiment of immorality. The teacher, who has accepted a man's penis deep inside her body for the first time, experiences repeated lustful orgasms as she learns a new subject: pleasure. A shocking work worthy of the name of this major new star.
