He is right of course, she knows him for a long time, but she never knows what he is going to do.
To be honest, she doesn't even know exactly how he looks. He graced her once with a picture of his left hand, the hand he usually uses to cause her so much pleasure, but ever since she knew him he never let her see his face. She knows he is of brown complexion and she savors the gentleness of his carress, she knows he is large from the noise of his footsteps on her hardwood bedroom floor. But this is all. she prevertly enjoyed no knowing, but she knew he should never suspect that, because he might punish her for that too. She loved waiting bent over, spread legged for him. Excited from the noise of the door opening and his coming closer with each step.
Just thinking of that made her squirm. Suddenly she felt him slap her hard on the bottom. "I haven't told you to move" he said sternly but gently as she felt the imprints of his finger get alternately warm and cold on her posterior. She instantly felt sorry and excited. "I didn't mean to displease you master. He caressed her again lightly touching her lower lips, sending shivers all through her body. His hands move along her body to grab her throat, the pressure almost too much, she blurs, her eyes flutter, but she deserves it all, she will not resist.
He kicks her to the floor and walk away.
"Now wait for me" he whispered as she felt his warmth moving away from her, and she spread her legs just a little more for what's to come. Knowing that whoever he is, she belongs to him. Her unseen Master, the one she will wait for, forever.
