I was traveling back from my job yesterday on the coast of Oregon and stopped off at the adult arcade in town. When I entered I saw this good-looking guy about my age and I smiled at him and then went to the back where the booths were. In this arcade half the booths have large holes in them to view your neighbor or enjoy each other's company however you like. Just after I put my money in the machine the door next to my mine was opened and my friend from out front sat down. We both slid down our pants and were rubbing our cocks through our underwear. I was extremely hard already and released my 7' cock from my briefs and added some lube to the head of my cock. Next door my friend had out his smaller but hard cock and was matching me stoke for stroke. I motioned for him through the hole to come next door and join me.
Thirty seconds later both of us had each other's cocks in our slick hands and were having a great time beating each other off. Then what surprised us both was somebody else entered next door and sat down. The biggest, blackest cock came through the hole that had to 9' and we both smiled. My friend was now stoking this huge cock with his left hand and my hard cock with his right. I took my free hand and held his big black balls in my hand and massaged them. This had to be the hottest masturbation session I had ever had.
We beat each other off for about five minutes till I couldn't stand it anymore and I blasted my load all over this big, black cock that looked so awesome sticking though the hole in the wall. My white load looked so hot dripping off his thick, long cock. My friend was beating faster now with my added load for lube on this cock. Just as I looked down, this huge cock let loose with a load that sprayed my friend's chest-he must have shot six huge ropes all over the place. Our booth smelled like sperm big time.
