I got listening to my sister and her friend talking. I wondered what it was all about.
So Claire my sister, had her real hot friend Amanda round. They were talking about making out with their boyfriends and it was all pretty gross. Amanda said something about what she did with her boyfriend makes her 'cream her panties' Clair said that she often does that and 'it gets real wet down there.' Now I knew they were talking about sex and all, and I guess it got me hot. Later that night I couldn't sleep and went to the bathroom. When I got there I found Claire's used panties on the floor. I picked them up and found the stains in them. I smelt them and they smelled pretty darn good. Then I wondered what it would be like to have a wet crotch like girls have so I put them on. Instantly I was hard as a rock. Claire's little cotton panties were kinda under my cock but I could feel her wetness between my legs and it felt so horny.
I walked back to my bedroom wearing them. I reached behind me to shut the door and put my hand right on Claire's tummy. She had followed me. There was a moments total silence then she sat on the bed and put her hand on my knee and asked me really gently how it felt. I don't know what happened to me, but I drew my knees up and said to her 'Claire my pussy feels so wet' She put her hands on my knees and gently pushed my legs apart. She stroked the panties against me and said 'Oh you poor thing. You need a good seeing to, you naughty girl!' All the time she stroked my wetness.
Then I felt her hand on my cock and she started to jack me but she said 'Hmmm. Your clit is hard too isn't it?' She jacked me slowly almost painfully. Then she said 'You need my finger in your pussy you slut.' She pulled the material to one side and pushed her finger into my ass. I came so hard it shot over my head and hit the wall!
After I came down, Claire hugged me and said we should be 'girls together.' This led to some interesting experimentation. I love being her girlfriend. Sometimes she lets me finish her off. She calls me Jenny. One time she actually licked me through 'her' panties. Part of me thought it was so kinky, my own sister licking her own pussy juice. Lately, she has been making me use her friends used panties whenever possible. God I feel so horny!
