Let go, and concentrate on your body. Are you angry at me, slave? Angry at your mistress? Angry at the pain in your nipples and the ache in your balls? You might be, but some part of you, deep down craves this. For we are your mistresses and without us, you would not have life. You deserve to be there, knelt at a womans feet, ready to do her bidding. For some women, it's sex. For some, it's work. For some it's both. But no matter what the requirement, your purpose is given to you by us, your creators.
You know very well what it's about for me.
*laughs*. Untie your balls, and when you're done, remove the clamps from your nipples.
