my sister started baby sitting for the next door neighbor when she was .I was jealous because she always had extra money .
one evening I decided to pull a trick on her to scar her .I was going to sneak over and knock on the windows .and hide .but when I got close to the window .I heard some real loud squeaking and moaning sounds coming from the room ..I looked in the window and I saw my sister and the next door neighbor's husband on the bed 'he had her legs pushed up close as far as he could get them and he was ramming his big huge cock in her pussy as fast and far as he could .my sister let out a low scream and wrapped her legs around his ass and started bouncing her ass up and down on the bed .
my pussy got wet just watching them fuck .I just couldn't take it any longer I reached up and banged on the window and busted out laughing as loud as I could .
the guy pulled his cock out of my sister and grabbed his pants and pulled them on then he ran out the back door and grabbed me and pulled me in the house .
y this time my sister had her panties on and her skirt pulled back down .she saw me and started to cry .she ask if I was going to tell mom .
I told her no but I want some money .and the next time you decide to fuck I want to join in .
so now my sister and I both fuck the next door neighbor's husband
