One night I decided to have some fun with S, I wanted to give her a real test, to see just how she'd react, it went better than expected, she'd just bought a new black catsuit, a lycra one, and some more black boots, they were known in the 80's as 'pixie' boots and most girls owned a pair at one point or another. We went to this little country pub, not far from a well known lancashire dogging location, she was wearing the boots, the catsuit and a pair of panties, no bra, as was becoming the norm by now. We went into this little pub and sat in a quiet little alcove, apart from a few locals on the other side, the pub was empty. I got S on the lager as I knew it made her need to piss and just for good measure gave her a couple of brandy and coke's, they'd liven her up. She'd had several drinks and mentioned about needing the loo, I pointed out where it was, then played my wind up, I told her to be careful as I'd heard there was a hidden camera in there. it was at this point that she realised that the only way to use the toilet was to almost remove the suit completely, not something she fancied if there was a camera watching. I bought her several more drinks and her bladder was visibly swollen, to add to the fun I popped off several times to the gents toilet, it was begining to get to her, finally she said if we didn't leave soon she was going to do it in her pants, I reached under the table and felt her crotch, it was damp, this meant only one thing, she was leaking. We had one more drink, just to pile on the pressure and then left, she made it to the car without wetting herself but only just, she couldn't hold it all the way home so we parked up at this dogging site, it was deserted, luckily for her. She got out of the car and realised there was no cover, she was in trouble, I had told her that she mustn't wee in the new catsuit, but she didn't want to strip naked in the middle of the car park, it was then that I offered her a possible solution. In the back of the car was a pair of black leggings, I kept them there for her in case of an emergency I suggested that she take off the suit and put on the leggings, I'd allow her to wet them, so it was either that, or get naked, she chose the leggings. She managed with some difficulty to get out of the suit and into the leggings in the back of the car, all the while she was trying not to wet herself. She puts on the leggings and her boots and then realises she has no top, not even a bra, but by now it's too late, she jumps from the car and loses it completely, she's pissing hard into her panties and leggings and it's running into her boots, all the while she's stood there with her tits out for anyone passing to see. I hear a car approaching but S can't move, she's still pissing in her pants, I switched on the car headlights and what a sight it was, a slim sexy blonde, stood topless in the middle of a car park pissing in her pants, I think the driver of the other car got a good look before driving off. She got back in the car and we drove all the way home with her sitting in the front seat topless, some people got a real eyeful that night.
