Monday afternoon

It all started on a Monday afternoon, I had just returned home from school and I went upstairs to change into my work clothes and begin my yard work. Mother always made sure I did the yard and she was extremely picky about how it looked. As I got to the top of the stairs I heard a strange sound, almost like moaning. I took another step and was in front of the door to my sister Judy’s room. The moaning was coming from her room alright. I stepped up and looked inside. My jaw damn near hit the floor. There was my sister on her back on the bed with her legs spread wide and a HUGE black dildo working in and out of her pussy. I caught my breath and stood there, unable to move. She worked this black monster in and out of her sopping wet pussy at a torrid pace. She began to shiver and exploded into a very violent orgasm, with her juices literally running down her legs. She slowly returned to earth and opened her eyes only to see me standing there with the largest erection of my life, holy fuck was I excited. I figured I was a dead man, but instead she pulled the big black cock from her pussy and licked it clean all the while staring at me. Then she started smiling and said “It’s about time, I’ve been waiting for you for a while. Come here, we need to talk”.
I couldn’t speak anyway so I just stumbled into her room and over to the bed and stood there looking at Judy. She is 18 years old and extremely hot. She is five foot six tall with long black hair almost to her waist. Green eyes that almost glow and a perfect complexion. 34D tits and a 23 inch waist. I know these measurements now after having measured her after this happened. Her ass is by far her best asset. It’s perfectly shaped like all the TV infomercials and butt lift videos. 37 inches of man pleasing pussy and ass. Perfectly groomed with no hair, only a small landing strip above her oversized clit. Her navel is pierced and has a long ornament that hangs from a chain and really turns me on.
“I’ve been thinking of this for a while now” she said, “And I decided today that I was going to see what would happen and what you thought.
