My girlfriend and I have been together for over 7 years and her younger sister Charlotte was 10 when we first started going out.

She's now 16 turning 17 soon, and I've started to look at her different. Charlotte has a beautiful face and has really started to become a woman.

She's very petite and has a great little ass. I've found myself looking at her ass recently and imagining what I'd do to it.

I recently went round her parents house where she lives. I went upstairs to the toilet which is next to charlottes room. I crept in and saw that she wasn't in there.

I walked over to the draws and pulled one open. Charlotte had a selection of thongs and knickers.

I pulled out a couple of thongs and quickly took them to the toilet. I sat there and wrapped charlottes thongs around my dick. I wanked while smelling the thongs. I imagined getting my hands on charlottes perfect little ass, and licking her tight little ass hole.

All I can think about now is Charlotte wearing those thongs. Maybe I will have to go round one day and fuck her.
