Mai Shirakawa challenges "Riding Position Time Trial!" If she can ride a man in the riding position within 5 minutes, Mai wins! If she can't, she has to take a penalty game! Mai quickly listens to the simple rules and makes a plan. Since the match is 5 minutes after insertion, Mai stimulates the penis with fellatio to make it as easy as possible for him to ejaculate comfortably before the start. When the penis is hard, she inserts it from the riding position. Mai vigorously shakes her hips up and down, left and right, to force ejaculation, but can she ride him within 5 minutes? Please enjoy the continuation in the video!
