My friend's wife is a lewd tutor

By chance, Kaori ends up teaching English to Sato, her husband's junior, and when she sees her panty shots and breasts, she suddenly feels aroused by the junior's erect penis, and not only does he act like a slut, but he forces him to ejaculate with a hand job. Later, when Tanaka hears about this from Sato, he goes to the Nishio family to ask Kaori to teach him English, thinking, ``Maybe I can too...'' However, he is unable to concentrate on his studies due to all his naughty fantasies... When Kaori saw Tanaka like that, she realized that she was expected of him and started giving him an obscene English lesson.
