Stop stroking.
Start squeezing your balls until I tell you to stop.
Notice how they feel in your hand? Notice the pain you feel in the balls themselves?
If you didn't have any you wouldn't feel that.
you could be Her little bedroom slave...getting Her male lovers ready to fuck Her...cleaning their cum from Her pussy or ass when they were done. Maybe She would just squat over your mouth and let it drip out instead.
Squeeze a little harder.
She might train you to be Her toilet. Most slaves love to drink the Golden Nectar that proceeds from their Mistress. But, there is much, much more to being a real toilet slave, spew monkey. I can tell you that toilet paper costs go down significantly with a fulltime toilet slave in the house for EVERYONE to use. So, that is a plus...for Mistress Denise.
Squeeze those balls as hard as you can for one minute.
Then, we will proceed.
