Total Obedience
"Go ahead slave, make something happen. I mean, you don't want me to get bored with you, do you slave?"
"No mistress Stella"
"Good, because that would mean that we both would have to devote ourselves to some other activities slave, which i'm pretty certain you wouldn't like.."
(You keep rubbing yourself over your underwear until you're hard)
"Ready to show me?. C'mon, I want to see a nice, big, cock bulge when i turn around again slave. I want it at it's hardest, just like your mistress deserves.."
"Y..y..yes mistress Stella"
"Well, since you're at it, why don't you keep rubbing yourself until you have a nice, little stain in your underwear, go ahead, make it drool slaveboy, drooling like a dog. I want every single inch of that cock rigid and throbbing in your shorts, sticking straight up in the air.."
(You keep going)
"Massage your balls with your other hand, those poor blue balls.."
