A challenge, huh? You know I can't help but love a little competition, what did you have in mind? You're kidding, right? You really think you can outlast me in masturbation competition? Alright, but we better make this a little more interesting. If I win, I get to do some post-orgasm tormenting to you, and if you win (which you won't), I'll strap my vibrator to my clit on high for 10 minutes. Sound like a deal?
