a student suddenly shows up at home. konatsu, who is well-behaved in class, lets her in without suspicion. she says she needs help with studies, but once inside, she seduces me with her bare breasts while my wife is nearby. i can't help but get hard, and she uses this against me, making me her plaything. she keeps milking me for orgasms, and her true nature as a brat comes out more and more. i realize she's trying to take over my family, so i decide to teach her a lesson with my adult cock.
