I looked up with wonder and excitement as she straddled my face, and slowly lowered herself onto me. I shifted my mouth so that it would be right under her open pussy, my tongue now straining for as much as I could get. Then she was on me, slowly more and more weight coming down on my face as I moved my lip and sucked on her to try to give pleasure. I felt her heels slide across my hips, and then dimly heard the clack against my chastity device as she bounced it side to side. Her heel would jab at one of my balls now and then, causing me to grunt beneath her in a way she likes. When I needed more air, I felt her shift her legs closer together, and with true fear felt her stiletto heels pinning my scrotum to the floor. When she shifted her weight so that I could breathe it felt as though she had nailed my sack to the floor. I drew in a full breath, and screamed. I was still screaming when she settled back onto my face. She did this three more times.
Finally, when my scrotum was so numb from her heels that I could keep from screaming when she lifted herself, she shifted forward and I knew I'd be cleaning her asshole as well. I put my tongue out, as wet with saliva as I could get it so that it would slide right inside just as she sat, the way she likes it. The musky taste filled my mouth and seemed to penetrate all through my head as I snaked my tongue in and out of her. My heart was racing, and my cock was being pinched mercilessly by the pins in my chastity device. I felt her heels jabbing at my balls to encourage me, and I heard the sweet song of her moans of pleasure. I knew that this was where I belonged, and I felt true shame at having failed her earlier, and hoped that the punishment would be every bit as terrible as I expected.
