A female student on her way home from school is approached with a surprise request: "Would you like to suddenly come into the bath while your father is taking a bath and seduce him with a 'close contact bath mission'?" If the father can endure sex with his daughter, he will receive 1 million yen! This is a surprising plan! Before the challenge, the daughter said, "There's no way you'd be excited about me, your daughter!" But the father's penis is fully erect as he is pressed against his beloved daughter's body, which has grown more than he could have imagined! Will the father, who is still in heat, have forbidden incestuous creampie sex with his daughter without his mother's knowledge!?
