Ooooh... poor slave... does your balls hurt ? Don't worry slut, soon they will burst !! *giggles*
Now, get the plate. Put it on the floor, at my feet, and kneel in front of it.
Good. Now, still kneeling, keep your feet together, but spread your legs wide. Sit back on your thighs.
Open wider. I want to be able to see everything clearly.
That's good. This is My cock and My balls, now... Do you like to lend your cock and balls to your Mistress, slut ? Answer loud.
Very well... Now, start stroking, slowly and gently. I want ten slow strokes, ten fast strokes, ten slow strokes, ten fast strokes, etc. You must continue like this for two minutes, bitch... i'll drive you crazy, for sure :)
