SDAM-118 My older brother is the one at fault for coming into the room while I was alone, so take responsibility!! My cute younger sister, left frustrated right before reaching the finish, can’t calm down and ends up pinning her brother down, straddling him, and giving in to her pent-up feelings…

The younger sister, who loves to secretly pleasure herself, is furious when her brother walks into the room just as she is about to climax. She pulls down his pants, confirms that he is aroused, and immediately takes control. Riding him in a vigorous up-and-down motion until she is satisfied, she keeps going with intense thrusts. Though confused by the unexpected situation, he can’t hold back and ends up releasing repeatedly. Three younger sisters appear.
