First time true story:
I was 17 and returned to Miami after Navy boot camp, no sex or even a jack in 12 weeks, too many other guys around. I walked to the corner 7-11 to buy a penthouse mag. (you know why) On the way a guy on a Vespa motor scooter pulled up along side me at the curb. A nice looking guy, I recognized as the younger brother of a old class mate of mine. He asked if I needed a ride, (I was in uniform) and I told him sure, and I got on the back of his seat on the scooter. I was pressed against his butt on the back seat of the scooter and we rode around for about 30 minutes. He said he had to piss, and when we were in the rooming house district and he stopped in an alley and asked me if I had to go, I said yes, and we walked up the back stairs into a darkly lit bathroom with one toilet and sink. We both pulled out our cocks to piss, but we stood in the darkness unable to go. He brok the silence, and said his cock was too hard for him to piss, I said mine too. Then, without a word he then knelt accross the toilet, put his hands over my cock and sucked my hard 7" cock into his mouth. The warm sensation of his sucking mouth on my cock was almost too much, and in seconds I unloaded a wad of cum that shot spurts out for a full minute. He swallowed every drop of cum I shot, and then stroked my cock slowly with the tip still in his hot mouth. I leaned back against the sink and held on as he finished sucking every drop out of the head of my cock.
We then took the piss we came for and returned to the scooter, he dropped me off at the 7-11 and drove off into the night.
