For many years I used to like using public toilets for wanking. There used to be rather more sexy pictures drawn on the cubicle walls, and often some descriptions of sex acts. One day I was driving in Yorkshire, and stopped at a rather seedy roadside loo. I was already extremely randy, being in my early 20s, and what I saw on the wall made me want to shoot my load at once. I just couldn't wait. I undid my belt and lowered my trousers, then immediately put my hand in my Y-fronts to start masturbating. It was so exciting that I couldn't stop to push my pants down, but just carried on rubbing my large circumcised cock. The resulting feelings were incredible, getting more and more tense, warm and fruity. In next to no time a tremendous pulsation sent a great wad of sperm into my pants. It felt amazing because the end of my cock was pressed hard against my straining pants, so that the fluid could hardly get out, and this gave an incredibly sensitive and overwhelming feeling on the glans. The second spurt was just as wonderful, and there were, as usual with me, five more spurts before it all stopped coming out.
The only snag was that everything felt so sticky and uncomfortable during the rest of my drive to Leeds.
