"My husband... I wonder where he is and what he's doing..." My sister-in-law mutters, drinking alcohol and venting about her husband. Soon, her cheeks slightly flushed, she begins staring directly at my crotch. "Hey... want to try it?" Losing all rationality, as if her pent-up frustration has finally reached its limit, she fiercely latches onto my cock. This horny sister, unable to control her lust even with her brother-in-law, explodes with desire. Throughout the forbidden creampie sex, she cums wildly like a beast, lost in the taboo thrill of it all.
