My kinky, nasty, sinful, girlfriend Carolyn loved to masturbate or have sex and fantasize about my innocent step-sister, Ashley.
Ashley was about 18-19 at the time and was a country girl living in a very small town in the south. She was very innocent and a preacher's daughter at a rural, country, Baptist church. She played the piano at the small church on Sundays.
One afternoon Carolyn and I were out in the country partying and having a good time. Carolyn was a very wicked woman and loved to fantasize about doing nasty, sinful things.
We were driving around and passed the church and saw Ashley's car parked alone there.
Carolyn was bi and loved to talk about Ashley's fair skin, her freckles, big nice tits and innocence. She also liked to talk about seducing her and watching me fuck her.
We parked and quietly made our way into the back of the church past the Sunday school rooms. When we got to the men's bathroom, Carolyn opened the door and took me inside. She went into one of the stalls. None of the stalls had doors. They were completely open and anyone walking in could see whatever was going on. This was an old church and an old bathroom. Carolyn wasn't wearing any panties and pulled her dress up and lifted up all of the toilet seats and sat down on the dirty, piss-stained toilet. She was a little high already and horny. She pulled her pussy lips open and started showing me her pussy, asking me if it looked nice and dirty. I said fuck yes.
She started talking about Ashley and playing with her pussy making me very hard. She dared me to go out into the church with her and expose myself to my step-sister. I was so turned on. I asked her to come with me. Ashley was practicing hymns as we walked in. I walked up to the piano and she was happy to see us. She could tell we had been partying and mentioned it. She continued playing as I walked up to her and I pulled down my shorts and held my cock next to her right arm that was playing the piano. She stopped and looked at it with both shock, surprise and amazement. She was the stereotypical, dumb, blond cheerleader but I knew she had a part of her that questioned the wild side. She had just never had a chance to give it a try. She also looked up to me as I was about 8-10 years older than she was.
