I find you sweating when I return to the glass door. You are squirming within your confines, the wet vibrator having slipped out of your sopping pussy some time ago. I release the clothespin from your left nipple, eliciting a scream from your lips as the rush of blood comes back into your abused flesh. I reach down and tickle your wet folds, smiling as your hips jerk forward involuntarily, your muscles clenching for anything to relieve your plight of being teased without satisfaction for so long. Once your breathing becomes ragged, your breasts heaving, your eyes closing as you feel yourself climbing to a climax, I withdraw my hands, leaving you hanging, literally.
I chuckle as I gently tug on your nipple ring. You begin throwing some rather colorful names at me, but I silence them with some duct tape. I place the collar and leash around your neck once more and unchain you from the sliding glass door.
You were lucky this night. No one saw your plight. But you might not be so lucky on other nights. In this neighborhood, no one would help you.
Being the smart college girl that you are, you remember earlier and get down on your hands and knees as I lead you inside again.
It's time to get you prepared for a little work out. I lead you back down two flights of stairs and into the room you woke up in. Directing you over to a machine reminiscent of a bike, I tap your bottom with the leather whip I have in my hands. "Up you go," I command.
