The couple Saki, who purchased a new apartment, ended up staying at their brother-in-law's house for a month until it was completed. Energetic and usually highly sex-driven, Saki gradually became frustrated with unmet desires, but her husband refused to have sex because they were at his brother's place. During the day-to-day life of being alone with her remote-working brother-in-law, Saki could no longer endure just masturbating… 'Let's try each other's bodies' she said, blowing away all reason and instinctively devouring her brother-in-law's dick! An affair NTR sex!!
