I woke up that morning feeling a little bit worse for wear, god how much had I had to drink the night before? As I began to piece together the events of the previous evening I remembered something, oh no, somebody tell me I didn't really agree to what I seem to remember agreeing to, or did I, a quick read of the text message on my phone confirmed my worst fears, I must have been really pissed last night! It had all started a couple of years earlier, a group of us in the pub, lads in their early 20's, had formed a sort of club, we drank together, socialised together and fought together, just like any other group of young lads, but we had one difference, we also had a habit of dares and bets, it worked like this, someone would suggest something, or it may have been something that had come up in general conversation and then someone would be dared to do it, and there was usually a small side bet involved, a bit like some of the groups you read about at posh private schools. Sometimes the acts were spur of the moment, an attractive girl would walk in and someone would say something like, " I bet Paul can't get a kiss off that girl", Paul would take the challenge and it would usually be followed up with something like, " a fiver says you don't do it", if Paul got the kiss, then the challenger paid him a fiver, if Paul didn't then he paid the fiver to the other bloke. Sometimes the challenges were more planned, like daring someone to say place a cone on the head of the statue in town, that usually took a couple of days, lots of silly stuff really. Anyway at the time I was working at a riding stables, maintenance work, I liked it there was no hassle and the girls were quite attractive, well there's worse things to look at at work.several of the lads were quite envious of my job, granted they were on more money than me but it was the women, I mean, what bloke doesn't like to look at a firm little bottom in tight jodhpurs! One of the guys had been going on about these women for a few days now on and off, he'd heard stories about how they were always horny and usually good in bed, had I ever had any experience of any? I told him I'd been out with a few horseriders in my time, and yes, they could be quite sexual at times, some were downright kinky too. Well this particular night we were having a fairly heavy session and once again he brought up the subject of horseriders, "how do they go on about toilets when they're on a long ride?" he asked, I explained that most of them would just tie up the horse to a convenient tree and pee behind a bush, if they were on a road or something similar, they'd just have to hold it. "cor, I'd love to see one of them not manage it, imagine her wetting her tight jodhpurs, now that would be a sight" he went on, sounding rather excited by the prospect, at this point I mentioned that I'd seen it once or twice, well the aftermath, a girl would come back to the stables and her jodhpurs would be wet, and only her jodhpurs, a little odd considering it was a dry day, I also told him about a girl I had dated who actually had a fetish for doing it in her jodhpurs. It was at some point during this conversation that he'd said he bet I couldn't get pictures of a girl doing it in her jodhpurs, maybe it was all the beer, or maybe it was because I wanted to prove something to this guy, that I accepted the challenge, as to why the bet had ended up at a hundred quid, well god only knows, all I knew was I now had 2 weeks to either get the pictures, or fork out a hundred quid, how the hell did I get into this? I was sat in my little cabin at the stables pondering the problem when in walked Martini, that wasn't her real name although it was what most of the girls called her, she'd a reputation for being a bit of a good time girl and a few years earlier there had been a drink that was popular called Martini, it's advertising slogan had been 'any time any place anywhere' , one of the girls who had been at the stables at this time had said it reminded her of the other girl, and ever since then she'd been known as Martini! She needed a small repair done in her stable and I wandered back with her to carry it out, we chatted as I worked and she made some comment about me seeming a little rough that day, I ended up telling her about the heavy night before, and about the bet, getting as I put it, a girl to go to the toilet in her jodhpurs, well it sounded better than saying I had to get pictures of a girl pissing herself! She looked at me in silence for a few moments, "ok, so you get to win your bet, but what does she get out of it, after all, you could hardly expect her to do it for nothing could you?" she asked, she had a fair point, not as far as I could see that it was going to happen, it was all academic really, I was going to lose the bet. "well, I suppose I could buy her some jodhpurs, that way she'd not be doing it in her own" I replied, "oh, and what happens to them afterwards?" she asked "well, she could keep them, I suppose they'd be ok after a good wash" I replied, begining to wonder where this was going. She looked down at her long shapely legs encased as they were in a pair of well worn black jodhpurs and long rubber riding boots, "ok I'll do it, I'm a size 10, just tell me when you're ready, oh and make them blue" she smiled wandering off across the yard. I went home that night and made a few enquiries and a few days later, for around twenty quid I was the owner of a pair of pale blue jodhpurs, size 10. I went to work and told Martini that they had arrived and they were in the back of my car, at lunch she came over to look at them, she said she was happy enough and told me to bring my camera with me on Saturday and everyone else would be at a show, "oh and bring something to drink, it always puts me in a good mood" she giggled as she went back to her stable. Saturday came and I went to the stables around mid morning, sure enough it was deserted, except for her that is, she'd fed her horse and cleaned the stable, we had until mid afternoon to 'do the deed' as she put it. I handed her the bottle, a bottle of cheap white wine, not a particularly good one, but it was 15%, that should put her in a receptive mood, "got the jodhpurs?" she asked, opening the wine and taking a good mouthfull, I nodded and went to the car to get them. Once I returned she told me to come into the stable and close the bottom half of the door, that way if anyone did arrive unexpected they wouldn't see what was going on. She stood up and pulled off her grubby looking riding boots, then without hesitation she took off her jodhpurs, she wasn't the least bit embarrased about doing this in front of me and I was begining to believe the story behind her nickname. "you don't mind if I keep these on do you?" she asked, pointing to the white skin tight cycling shorts that came down to her mid thigh, and did little to hide what was beneath. I shook my head, "not at all, feel free", she pulled on the new jodhpurs, and smiled, they were much tighter than her old ones and made her look even sexier, "mmm, very nice" she said, stepping back into her boots. For around the next half hour or so we sat on the straw and chatted, "I'll be ready soon, I've been saving this since yesterday" she giggled, squirming slightly, "and by the way I feel I can't hold it much longer". Shortly afterwards she finished the wine and got to her feet, she looked outside, it was still deserted, "get your camera, I can't wait much longer" she giggled. I took out my video camera, an old 8mm, we didn't have camera's on phones back then, "ready?" she asked, stepping back into a corner, I nodded my head, pointed the camera, and hit record, "just don't show my face, ok" she said, parting her legs slightly, I just nodded and kept the camera firmly pointed at her lower body, it wasn't her face I was interested in. "here goes" she giggled, I watched as a dark patch appeared on her crotch, slowly two streams began to run down her thighs and into her dirty rubber boots, finally it stopped, "and now for the money shot" she said, turning her back towards me, I continued to film the dark stains on her inner thighs, " here we go" she giggled, "get ready", I was a little puzzled as to what was going to happen, she'd already wet her pants, the deal as I thought it, was complete. She stiffened slightly and then it happened, suddenly the back of the jodhpurs began to tent outwards quite noticeably, she made a couple of soft grunting sounds and a bulge began to appear, and quite a substantial one, finally after a couple of minutes it stopped, "there, will that do you?" she asked, gently patting the bulge with her right hand, I nodded, yes perfect, she turned and smiled, "won't be a minute and then you can give me a lift home" she picked up her old jodhpurs and headed off across the yard in the direction of the toilet, she returned a short while later dressed back in her old jodhpurs, I've bagged the new ones and my shorts just need burying in the muck heap, we don't want anyone finding them do we? she said, smiling, she headed out of the door, the plastic bag containing the wet jodhpurs in her hand, "come on, lets do this and then we can go" she told me, heading towards the muck heap. She handed me the bag and told me to hold it,then she took a spade and stepped into the slimy liquid that oozed from the back of the muck heap, she poked about in the thick ooze creating a hole and dropped her once white shorts into it before covering them with the slimy black filth, "good, nobody will find thm for a while, and when they do they won't know who they belong to" she giggled, she walked over to the tap and hosed the slimy black ooze from off her boots, finally we walked back to my car, got in and I drove out of the yard, "that was lucky wasn't it?" I said as we pulled out of the yard, " what was?" she replied, looking a little puzzled, "well, you keeping your shorts on, it would have made a real mess of those jodhpurs when you had the accident otherwise", she thought for a moment, " what little accident, it was what we agreed wasn't it?" she replied, now looking totally confused, " well to be honest I was only expecting you to wet yourself" I answered, "so you didn't want me to shit my pants then" she asked, bursting into laughter, "I thought that was what you meant when you said you had to get pictures of a girl going to the toilet in her jodhpurs" We both cracked up laughing, "still at least you'll win the bet and you can't tell me you didn't enjoy it" she went on, then added, anyway, you got what you wanted, and more plus I had a laugh and got some new jodhpurs into the bargain" I pulled up outside her house, "true very true, but each time I see you wearing them I'll be imagining that bulge in the back across your sexy little arse" I told her, she smiled, "and I'll know what to do next time I need some new jodhpurs" she giggled, it was a bargain. I watched her sexy little arse as she walked up her drive, she never did get to earn another pair as I moved to another job not long after, still I won the bet, got my money and learned never to make such an expensive bet in the future, I'd stick to fivers and tenners from then on!
