My mother's uncle babysat me the summer I was 11yo. He was recently out of prison. We spent many days wrestling in our underwear - with increasing amounts of intimate positioning. Oddly he kept telling me never to let men touch my private parts - as a course of daily casual discussion. One morning - I was laying on edge of bed w legs on ground watching morning kids show - uncle approached me - pulled my pajama bottoms underneath my cheeks. Now I regret being a good boy and resisting - he put an arm on my back and significant weight to stop my squirming. Then I felt something caress my ass crack up and down. I remember hearing a slight slobber - he had traced my ass with his fingers and tasted them. He tried to fully lay on me but I got loose and he never tried anything again.
