I am so hard and turned on with my young son watching me that I pull my shorts aside and expose the fullness of my throbbing penis. For some reason this turns me on even more. I half moan that 'Daddy is just making himself feel good' as he perches at the bottom of my yard recliner. Three things happen: my breath gets shorter, the edge of my shorts rides up my thigh uncovering the head of my penis, and my young innocent eight-year-old son becomes curious as to what I am doing and why I am breathing so hard. I rub my hand against the smooth fabric covering my burgeoning cock. The sun warms my blood and gives me that familiar itch between my legs. It is a hot august day and my eight-year-old son is splashing in the swimming pool as I doze off sunbathing in my running shorts, my chest and face exposed to the sun's rays to improve my tan.
