Long live this site!
Dad owned his own truck and two others. From age 13 when I reached puberty (I had a near six inch cock and could cum) I would go with him on short overnite hauls. Dad would hire a 'lumper' (a helper). When staying overnite, or on extended lay overs, I would wrestle with his helper and fondle his cock and balls. He would do the same to me.
I would initiate the cock play even when he was unsure that he should be foolin' with me. I was a very aggressive kid. We eventually would jack off each other when dad was out taking care of paper work or we would shower together which dad thought was OK.
At any rate, if I wanted a guy's cock I usually got it. Man, was I ever a horny kid and only a grown man's cock satisfied me. I out grew the five years of intense cock play at 18 when I got laid for the first time. But I continued getting cock for years, but not as much.
