SONE-975 Indonesian Subtitle - I Can't Stand to See My Girlfriend's Sister's Big Breasts - Ako Kimura. Kimura Aiko [Javsin]

The story focuses on the secret and sinful relationship between Hideo-kun and Ako, the biological sister of his girlfriend, Tsubame. The story begins when Hideo visits his partner's house and finds Ako often acting dominant and implicitly seductive. When Tsubame has to leave suddenly due to an emergency at work, the situation in the house turns naughty. Hideo, who initially tried to be faithful, is unable to resist the temptation of Ako, who has an extraordinarily sexy body shape and large muscles inherited from her mother. The two engage in wild games of lust ranging from sensual massage sessions, violent tit-fuck (paizuri), to extreme intimate relations repeatedly in various corners of the house. When Tsubame suddenly returns home, the two are forced to play cat and mouse in the midst of lust, hiding the scattered semen, and agreeing to keep this hot affair a secret for the rest of their lives.
