Have just returned from an interstate job, long road trip in a terribly slow heavy vehicle. I (55 m) and my colleague, (40's m) were on the road last night and had to stop at a pub in a little town in order to get some food before meal service ended. We both ordered and i hooked in to a few beers as i wasn't driving, dinner arrived and in all fairness it was damn good considering the remote location. After several more brews i was told to hurry up as we had to go. I decided to go to the shitter and empty before returning to the slow, noisy and uncomfortable vehicle. I picked the end stall and was happy to see real toilet paper on a roll and not waferthin squares in a box. Sitting for only a few seconds i saw the tail of the toilet paper move and thought it was probably just a breeze from the main door opening. Then heard a feminine voice say " show me your cock ", i looked around and noticed the paper tail pushed aside and a rather large hole in the wall and thought why the fuck not. I swiveled a little sideways on the seat and showed my cock to the hole, then a small hand and thin arm came through a little and the voice said " can I touch ", i slid a little closer and the hand grabbed my cock and started squeezing and stroking, I got hard and sat back enjoying the feeling of a female, presumably, jerking me off through the wall. It didn't take long and I spilled a couple of days worth of cum all over the hand and arm. The voice said thanks and I said no, thank you. I buttoned up and left, not bothering to mention it to my colleague. About 2 hours down the road we had to stop for the shitter again, i suggested my meal must have been dodgy, truth is i forgot to dump after my hole in the wall interaction.
