Nice girl vs. mean girl
SILVIA: Look at him. He can hardly wait to start stroking his pathetic cock.
TRACY: I can hardly wait either! I wanna see his penis throb. Can I please suck him off, Ms. Silvia?
SILVIA: Absolutely not. What did we talk about? That's exactly what he wants. A woman to gratify him. He needs to learn to appreciate women. He may only look.
TRACY: Shucks. I'm dying to have a big hard penis in me!
SILVIA: All right slave, start stroking. Medium pace. Get that fist pumping. You may now look at Tracy's breasts, but not mine, and NOT her pussy. Got it? Only her breasts.
TRACY: Mmmmm, that's hot! I hope you like my boobs! I like to pinch my nipples. Aren't you glad to finally be stroking yourself?? I bet it feels super good!
SILVIA: Pump it hard for us, slave. I want those balls purple when we're done! I want tears in your eyes. Jerk that cock off! But don't you DARE cum without MY express permission! If you squirt before I allow, you must wear pink panties under your clothes for a week. If you have no pink panties, you must go buy a pair. That probably only excites you more. Stroke it faster.
TRACY: Yes! Stroke for me, baby!*squeal*
