Haruka's daughter and her husband bought a house. Her mother-in-law, Ayane, feels lonely as her living together is coming to an end. One day, she suddenly finds out that her son-in-law, Makoto, is a big dick. Ayane, who was frustrated with her, couldn't control her lust and sucked on his big cock. Makoto drowns in her mother-in-law's ejaculation service secretly performed in her home. It should have been a relationship until she moved, but at some point I couldn't stand it without Ayane's body.
