KAM-138 Cheating Wife Maya Kikuchi Blackmailed by Father-in-Law into Repeated Sex

A young wife in her fourth year of marriage lives with her husband's father, and a busy husband is often away on business trips, leaving her frustrated. She masturbates but is caught by her father-in-law, who grins. Later, she has sex with a delivery man at home, and the father-in-law witnesses that too, using the cheating and masturbation as leverage to demand her body. She submits, and is then forced into sex at night, made to cum many times by the man she hates.
