Car park wank

Just got home from the most exhilarating experience that I have has for quite a while, I had been out for a drive and stopped at his quiet car park near the river. The car park looked onto the river and there was probably 5 other cars parked there. I was desperate to pee but there was no public toilets about so in desperation I decided to go at the back of my car. Checking no one was about I unzipped my pants and took out my semi hard cock, 6 1/2 inches of warm cock, and proceeded to piss on my rear wheel. Shaking off the remaining drops I got the real urge to start wanking. Again checking the cars around I inched my pants down, far enough to allow my balls to hang free. As if taking the cue my cock started getting stiff. I stood looking around as my pants fell to the floor. I was so focused on my wank I failed to notice a figure standing on the bank behind me. " you should do that in private mate!" He said. Startled I stopped mid wank and bent over to try and recover my modesty. " nice arse you got there" he s****ered. I continued to pull up my pants in embarrassment. "Don't cover up on my account, I like a nice cock and you have a nice cock." He said staring at my butt. By now he was only feet away and he appeared to be about 17-18 years old and very fit looking. "Please keep going " he said. Nervously I pulled my pants down and took a hold of my limp cock and started to slowly pull it, I was starting to get turned on as this young guy started to touch his own cock through his jeans. " you mind if I join you?" I nodded in reply as he pulled his rock hard cock from his pants. Mine was midget in comparison and I kept my eyes glued to it as we both started a slow wank. He reached across and touched my balls this made me jump he giggled and bent down "you want me to suck it?" without answering he pushed his mouth over my cock and gobbled me off. Pulling it out every so often to lick the head and suck in my balls he kept wanking getting faster he said he would cum if I will, never a man to refuse a cum I nodded and he withdrew my cock from his mouth and stood next to me and his wanking pace got faster and faster. Within seconds he said he was cumming and shot his white sauce all over my belly, cock and pants this got me on the verge of cumming. I told him I was cumming and he bent down as I shot my muck all over his face. He licked the cum from my cock, pulled up his pants and started walking off. As I started to dress myself I noticed a man in a car further along the car park standing next to his car with his cock in his hand, he had obviously seen everything. I quickly sorted myself out got in my car and left the park, as I was driving away there was the young man walking along with my cum still on his face, he waved as I passed. Looking forward to more visits to the river.
