Back in college days we set up 4 refrigerator boxes worth of cardboard into a sort of duct taped wall with 3" cut outs. There were blanket dividers, so no one knew who was inside. Anyone could enter either side of the divider to poke his dick through or a tit through or press a pussy against the hole. Or...anyone could be on the other side to play with whatever was available. It was very popular, but I was there (not in a stall) when the wall fell down. We just put it back up and went on.

We charged a $1 entrance fee--mainly to keep out school officials who wouldn't dare pay. The money was used for duct tape and pizza and beer.

I've wanked off many a time on a BR train but no TT sure what a BR stall is though.

Trains running from Southend to Fenchurch Street used to have no corridors and single compartments. I spent a couple of years commuting to London and catching a train in after the morning rush hour.

The journey took about 40 minutes non-stop so if I got a compartment on my own - I usually did- then I'd be stark bollock naked a minute after the train left and I would have plenty of time for a wank. Out would come my freshly purchased jazz mag (Escort and Fiesta were my first choices but Razzle would do) and it was down to business......

Going past Upminster I knew I had about 10 minutes tops - If I hadn't already cum - and I'd usually spunk over the seats. It gave me an added thrill to think that later that day a sexy city secretary/PA/salesgirl would be sitting on my spunk...

Those were the days...
