Manspreading, bulging while sitting.

A n experience I had with a friend. And his dad! I was riding in a oversized truck with my friend and his dad. By here was no third seat so his dad just put a lawn chair inside for me to sit in and placed it just about a foot behind them in the middle of the two of them. My friends dad was driving. It was a long trip so I was just relaxing and subconsciously had my legs spread open talking to the two of them. All the sudden my friends dad turned around and grabbed my crotch cock balls and all. I didn't relize until he grabbed my cock that I had a raging hard on. Née must have seen the outline of of cock and couldn't resist I don't know but it surprised the hell out of me. His dad just laughed real big like it was nothing. I didn't know what to think. I just laughed with him. Couriouswhat do you guys make of what he did? He could see I was very well endowed through m pants!
