Twist your mind around with a classic "Beat the clock" scenario. In the final edition to this JOI series, you will have a few minutes of mental and visual stimulation and then a short window to Masturbate and Cum. You must finish the challenge successfully FIVE TIMES before moving to the next level. With each progression, the window to orgasm gets smaller and smaller and the visual stimulation gets less and less intense. By the end your stamina will be WRECKED!! Have fun and Good Luck!
