One of my many fantasies when I was very young was to suck my dad's cock or even my grandpa's cock. My fantasy was stopping at a rest stop and following him into the booth area and going into the booth next to him. Looking in the hole and seeing him stroke his cock. He then gets up and puts the head of his cock in the hole and I can't help myself , I start licking the head and shaft before taking his big head in my mouth. It suck a turn on to be sucking his cock and I keep going trying too take it deeper and deeper. I taste his juices and I feel it pulse and then it spurts thick cum into my mouth and I suck out every drop. I wait a couple minutes after he leaves the booth to leave my booth. As I walk into the sink area my dad is at a sink looking in a mirror at me as he recognizes the person who just sucked his cock and swallowed his cum.
