Stepmother Riko lives alone after her stepfather passes away. Her daughter and her husband decide to live with Riko out of concern for her lack of energy. Living together was going well, but the son-in-law was living in agony every day. Her mother-in-law's body was so attractive that she fantasized about having sex with her mother-in-law. The son-in-law came home early. Her wife went shopping. Her son-in-law hugged her mother-in-law as she was preparing to take a bath, and her mother-in-law caressed her because he thought she was too attractive. Although she is a reluctant stepmother, Riko was originally a lewd girl. Even though she says no, her pussy reacts immediately and drips her love juices.
