A man is worried because he can no longer get an erection due to age. One day, his son brings his girlfriend, Akari, home, and the man falls in love at first sight with the earnest and quiet Akari. Wanting to have sex with Akari at all costs, the man gives his son a sleeping pill and applies a generous amount of aphrodisiac to his own cock. Then, before Akari can resist, he inserts his penis into her defenseless ass, worried about her sleeping son, and fucks her from behind, making her captive with aphrodisiac sex. A convulsive orgasmic NTR 3 scene in which she is made to cum so much that she can't resist her boyfriend's father!
