I loved smelling all the spunk, and especially seeing it drying on the TV screen. It really got me hot to think about the other guys who were so horny that they blasted huge ropes onto the screen. And then I would get so horny that I would join them in making a mess of the booth. Never apologize if you left a spermy mess in a booth ... it was very much a part of the fun in going in there in the first place!
It's easy now to forget how much money I spent searching the hundreds of channels of random stuff to find the hot shit that would get me off. Very frustrating. But I remember having some great orgasms in the booths.
Very nice to see guys with their cocks out, doing what comes naturally. When you're in one of those booths and the porn is playing and guys around you are moaning and cumming, all you want to do is get your cock out, get it nice and hard, and then spray your hot load everywhere.
