Ken-chan, who was supposed to have come to meet his friend, confesses his feelings for his friend's mother. The kind mother who responds to this desire gently slides down the laces of her panties on the dining table and says, ``Do you want to take a look?'' and shows her her clitoris. Unable to hold back, Ken-chan gradually escalates and enjoys a world he has never experienced before, including cowgirl, missionary, blowjob, and cunnilingus.
