Sayuri lives with her daughter and her husband in an apartment. Her husband was bland and she was always frustrated. One night, her son-in-law, who is interested in her mother-in-law's plump body, sees her masturbating, and she is forced to pull out a blowjob. The next day, her mother-in-law, who was forced to have SEX by her son-in-law, woke up to her woman, made each other's spouse drink sleeping pills, and two people began to enjoy rich SEX.
