We are sexually who we are based on our earliest experiences. I was a skinny but muscular kid with virtually no tits when an older guy started to pay attention to me. His name was Rusty. He'd play ball with me or go for walks, innocent stuff. Gradually he would expose himself by not wearing underwear or diving in the pool and "losing" his shorts. I was scared but fascinated.
He started to touch me in little ways the smack on the butt became a fondle. I wanted it to stop and I didn't, it was scarey but good. It was sexual molestation but I kept coming back for more, so he got braver. He'd grab a tit as we wrestled in the pool eventually "accidentally" moving my suit to expose me. I was mortified and really turned on too.
He asked if I liked that and I admitted I did but not when people I knew could see me. He asked if it was ok if he did it only when it was strangers around and I said I'd try it. The first time- he took me for a ride in his new car. As soon as we got on the highway he pulled my tube top down and told me just sit back and enjoy the ride, and I did! I was totally turned on by this as truckers honked and guys stared.
We kept this up for a while. A few weeks later we went to a park, he always liked to go for a walk and hang his dick out till somebody saw him. This time as we got out of the car he pulled me to him kissing me and he unsnapped and unzipped my shorts. He said just walk around like that. I protested that they'd fall - he smiled. They fell to halfway down my ass immediately showing my panties. We walked around for an hour with his dick hard and long poking through his fly and my pants falling off.
