while you weren't there, my fatherinlaw gave me a... AIKA

Maki, a young wife who began to live with her father-in-law, was single. During the day, his father-in-law who accidentally witnessed Maki's masturbation felt 'female' when he did not feel that he was a wife of his son and committed crimes without hesitation. He couldn't be told by his husband, and he could not refuse the father-in-law who was persistently looking for his body, and then under one roof, Maki groaned into a pleasurable coffin.
