Why not?

Because she is still following my first rule not to speak, I can tell she is enjoying the way this is going. I remove my finger from her bum and grab another piece of ice. Starting in the middle of her back I slowly trace her spine with the tip of the ice. It is like opposites attracting the way the cold ice seems drawn to her tight hot bottom. She tenses up as I slide the ice down her crack, but relaxes again quickly.

"Hey, you're not..." she blurts when the tip of the ice gets close to her tiny hole. She catches herself, but it is too late. She has broken the first rule.

"Well I may not have, but now that you've broken a rule, I have ****." I peer around, and the pout on her face is so contrived I know she is still pleased with what I am doing. I rub the ice in slow circles getting closer and closer to her asshole. The mixture of oil and water makes the ice extremely slippery.

When I reach the center of her hole I begin to push it in at the same speed as the creeping ice age itself. She inhales sharply, but manages to keep from tensing up. Finally, after what seems like forever, the piece of ice is all the way in. I take my finger off the tip, and the ice stays put. But when she rocks her hips slightly left to right the ice suddenly shoots all the way across the room, hitting the wall on the other side! Her knees buckle in laughter, and I have to catch myself on the counter to keep from falling on the floor in laughter.

We both regain our composure, and I grab another piece of ice. Standing behind her, I loop a finger of my left hand under her thong. Holding the ice in my right hand, I quickly push it in and snap her thong back into place all in one movement. I don't know if it is the shock of the cold again or the almost electric 'snap' of her thong in her crack--probably both--but she stands bolt upright spinning to face me. Her eyes are wide and her full lips are tightly puckered, and she does not make a sound.
