A favorite memory when I think I was 14 was fathers day when dad took me to a playground where there were several fathers with their kids. Dad sat on a bench and had me sit on his cock as he pulled it out of his shorts as several other dads watched. After there was enough attention he pulled out and shoved his cock back in in shorts and I followed him to a more private picnic bench where I took off my shorts, laid me on my back and held both my ankles in one hand and fucked me. He then let a few others fuck me while he stroked his cock watching me get used. I have chatted with so many that wish their dad had used them too and yet have not trained their own sons for which they too will have the same wish later. Having sex with dad brought us closer and felt like a bond for life that only fathers & sons can have.
