My sister Mel and her 12 yr old daughter Kim recently came to stay with me while their house was been painted and building finished off. Coming home from a run yesterday morning I heard my sis shouting to Kim to bring down her bed sheets and dirty washing to the washing machine. Hearing the shower in Kim's room I grabbed her laundrey basket and pulled off her top sheet. As I was about to take off her bottom sheet I noticed a wat spot and ran my finger over it and put it near my nose to smell. All I smelled was Kim's sweet smelling pussy and when I heard the shower go off I gathered the sheets and took them downstaires. As Kim joined us for breakfast my sister told her to say thank you to me for bringing her washing down. I watched as the coular drained from her face and smiling I said that it was no problem but she must be more carefull when she drinks water in bed. It has now been a full day and Kim can still not look me in the eye!!
