A father plants an aphrodisiac on his son's tutor. His body starts to heat up, his breathing gets rough, and when the aphrodisiac takes effect, the father attacks the tutor under the pretense of caring for him. However, the effect is greater than he expected... "Hiding from his wife!" "With his brothers who he bumped into while masturbating!" "He barges into his room without permission!" etc. The tutor, who is not satisfied, escalates! The normally kind tutor suddenly turns into a total slut!
