S-class beauty Emiri Momota has gorgeous breasts, a firm ass, a narrow waist and around five favorite cowgirl variations, making her perfect for this challenge. If she makes the actor cum while riding him within five minutes, she wins the prize; if she fails, she must take a post-orgasm deep-throat punishment. She warms him up with nipple play, a handjob and oral before mounting him. Upright bouncing, arched-back riding and grinding follow as she teases him with dirty questions, switches to reverse cowgirl without pulling out and keeps riding at full force even after time expires. Her attack makes her cum too, but she loses the challenge and finishes with a frustrated smile.
