My friend's girlfriend is a horny little thing who flirts with everyone all the time. She has a great little body but no one makes moves on her because she's dating our friend. The other day when she was hanging out and he was not around she asked me to give her a piggy back ride around the block. I said sure why not and scooped her up on my shoulders and we went for the walk. I enjoyed it having her little ass on my shoulders and feeling her crotch against the back of my neck. At first she had stuffed her skirt down between her lags but eventually it worked its way out and I felt the soft silk of her panty covered mound pressing against the back of my neck. I made sure to go for a long walk and enjoyed feeling her pussy rubbing against me as we walked. Then I started feeling a wet sensation on my neck and dripping down my back. I thought I was sweating and said hold on, my neck is sweating bad and she said "No it's not, sorry that's me." Man oh fucking man.
