"Maybe this will help you slave, me bending over for you like this?"
"Y..y..yes mistress Stella"
"What are you looking at?. My ass?, my feet?, both?. Should i slide my pants down for you slaveboy?. Are you curious about what's underneath?"
"Y..y..yes mistress"
"Well, too bad that you don't get anything that you want slave, you just get what i want. And what do i want slave?"
"T..t..to obey you mistress"
"Good boy, c'mon, squeeze it tighter, work your prick slaveboy. Really stroke it over your underwear, do it hard, like a real man would. And don't cream your shorts like a little girl slaveboy, behave yourself. If you ejaculate any cum from that incompetent dick of yours.."
"P..p..please mercy mistress"
"Hmm, you know, now that i think of it. I'm actually curious if you learned something so far slave. So why don't you close your eyes again while you rub yourself, what do you say?. Let's see if you're still having all this naughty, inappropriate thoughts swirling around in your head.."
