The husband's older brother's small, thin-walled detached house left the couple unable to have sex. Instead, the wife, Okuda Saki, took advantage of her brother's penis, which was right in front of her, becoming even more sexually aroused than usual. (SONE-358)

Newlywed Saki Okuda bought a new apartment, but for the first month before the renovations were complete, they had to stay at her older brother's and his wife's house. The lively and cheerful Saki has always had a strong sex drive, and as time went on, her desires grew stronger. However, her husband, being at her brother's house, was unwilling to have sex with her. During the day, she was alone with her brother, who was working remotely. Unable to endure it any longer, Saki said, "How about we try each other's bodies?" She abandoned all reason and instinctively and greedily indulged in an NTR (Netorare) affair with her stepson!
