(You feel sweat running down your body and you feel your orgasm approaching fast)
"It feels so good. I'm getting close mistress.. May i.."
Tess interrupts you again and says:
"No you may not!. What you do may though is to use your other hand and continue stroking. You see, now that you had your training, I expect alot more from you from here on out.. So right now i just want to see you stroke MY cock for me.. You know how much i like to see you doing that..right?"
"Y..y..yes mistress, of course mistress"
"That's better, good!"
