SONE-358 A lustful wife with the strongest sexual desire of anyone else, Saki Okuda, who moved into her husband's older brother's thin-walled house and, unable to spend the night, laid hands on the dick of her close brother-in-law.

Mr. and Mrs. Saki purchased a newly built condominium and decided to rent it at their brother-in-law's house for one month until the apartment was completed. Saki, who is energetic and has a strong sexual desire, is gradually becoming more and more frustrated, but her husband won't have sex with her, saying it's bad because it's her brother's house. Living alone with her brother-in-law who works remotely during the day, Saki can no longer tolerate masturbation alone.
