The Babysitter's Secret

This became our rhythm for the first ten minutes or so. I would pull her towards me, letting my rod slide slowly into her, then I would push her away, letting it slide slowly out. I could feel the tight muscles inside Jenny's bowels loosening, which was a good thing. I couldn't begin to really fuck her until I knew she was in no danger of any serious damage.

Jenny's body movement gave me the indicator I needed that it was time to proceed faster. As I pushed, she pulled herself. As I pulled, she pushed herself. Soon, she was pulling faster than I was pushing, and pushing faster than I was pulling. Effectively, she was fucking my dick with her ass, rather than the other way around. I began increasing my pace to match her. My dick was soon moving in and out effortlessly, although it was still deliciously tight in there.

As the minutes floated by, our tempo increased to a steady, rapid pace. In and out, in and out, I pushed my cock in and pulled it out. Soon, my conscious will no longer mattered, and my body was acting of its own accord. Jenny's body too seemed to be acting without instruction.

Our perfect love-making continued for an unknown amount of time. My thighs slapped against her ass and my balls bounced against hers with each successive thrust until the room was full of the smacking sounds of our frenzied passion and the air began to stink of sweat and other smells which might have been unpleasant at other times, but not at all right now. I was at last truly slamming my cock into her ass as I had been aching to do from the beginning.

I looked up and down Jenny's body. Her babydoll had bunched around her chest so I could see the smooth, white skin of her back. I leaned forward and kissed the back of her neck without breaking my stride, so to speak. Jenny turned her head and tried to kiss me, but couldn't quite reach. I knew what had to be done.

I slowed my pace until we had both stopped, then reluctantly withdrew my cock from her asshole with a sucking noise. I took Jenny by the thighs and flipped her over on to her back with one movement. She bounced on the mattress and giggled childishly.
