We call Jessica Ryan a Witchy Woman, but really she has fallen under Jack Hammer's spell. The powerful magic of bondage and discipline has her calling out for the opportunity to choke on his cock. The power, his power, just washes over her and clouds her mind. She is used to being the object of attention, using the charms of her amazing body and raw sexuality to turn men into little animals that she can command. She's going to have to get used to being the obedient animal.
It's the physical pain that has her so turned on. She hasn't really experienced anything like it. She wants to recoil or run away at first, but the way the rope holds her she can barely even shrink away. Instead she has to learn to settle into the blows as they come across her body. That's when things change. As she pushes herself to meet the pain head on she learns to love it. Once that happens, so does the begging. All she wants is to please her new master.
