I'm giving you exactly 100 strokes to cum. If you go over, it's cum denial, and you don't get to cum today. If you go under, you have to send me $1 for every stroke you cum early. No cheating! What do you think, are you up for the challenge? Keywords: JOI, JOI game, JOI challenge, masturbation game, jerk off challenge, findom, orgasm control, strip tease, pussy spreading Length: 10 minutes
