Cindy felt caught off guard, and much like a newbie she dropped her gaze to the floor. The only times she had been giving head were a few with her earlier buddy, it had been over soon and he had not forced himself deep in. She swallowed. "One, Sir."
"Only one? Well, you will learn that it is part of the duty and making of any good slave to be able to suck cock good, and to take it in deep. If you get through the years here you will know how to perform that service in many positions, on your knees, on your back, with your head leaning down from the bed and so on. But we need to train you,. no, slut?"
She shivered inside. "Yes, I think we need that, Sir."
"What do you need to know?" he asked with some emphasis.
"I need to learn how to suck cock, how to have my mouth filled with the cock of a man who...has me in his power."
"That is right, slut. And in what position do you need to begin?"
Cindy waited a moment. "On my knees, Sir?"
"Correct, slut. And to make you concentrate on sucking, you will have your hands bound behind your back."
Cindy knelt before him, and he undid her handcuffs, then walked around her and grabbed her wrists, now tying them off tight with hemp rope.
