Adventure of two young women being babysat.

I’m a disabled man in my fifties and pretty much stay watch her two young nieces for the month since she had to go help her mother. I told her I would do it but she needed to provide money for food for them. She gave me six hundred dollars and assured me she would be back by the end of the month. She introduced me to her nieces and left. The two young ladies were attractive and dressed very sexily. Since I had an empty bedroom they would sleep in my back room because I slept out in the living room. Friday night was an experience. It started out with them getting ready for bed. Coming out into the living room wearing very sheer short silk nighties that left nothing to the imagination. They joined me in the bed both climbing over me to watch the television. After about an hour the one next to me reached her hand back and started rubbing my penis. Groaning as my penis hardened they turned to face me. One pushed me onto my back and both stripped off their nighties and my sleep shorts. One straddled my groin and slid down onto my penis. My cock welcomed her warm , wet vagina. The other straddled my face presenting me with her beautiful wet aroused pussy. As one began sliding herself up and down on my hard cock I began eating the others pussy making her moan with pleasure.
