Look at my ass. It's just as perfect as my tits.
I want you to stare at my ass, lube up that "engine" of yours and start "revving" again. Take the end of that string in your other hand and tug on it while you stroke for me. Go on: Tug, stroke, tug, stroke, that's it. I want to see you at 7200 RPM. Right on the edge of failure. Push that "engine" of yours further than before. Tug, stroke, come on baby. Make your Mistress proud. Tug, stroke, stroke, tug. That's it bitch! You wanna cum all over this big round ass? You want my tits in your face? Well, too bad, get yourself to 7200 and maybe we'll talk. Don't ignore that string!
I want you tugging hard to keep yourself at 7200 for an entire minute without going over.
