A few years ago , there use to be some remote public toilets in the Malvern hills area which I loved to frequent on a Sunday afternoon for a bit of fun. Usually I would get dressed up only to find at best a quick handjob at the urinal and the blokes hardly noticed the fact that I had lingerie under my jogging bottoms. However on one occasion I was feeling really horny. It was a Sunday afternoon in November and not much was happening at home, so I made my excuses to my wife about needing to go out for a couple of hours and headed out to the car . Once off the drive and into the country I reached into the glove compartment to check my lingerie was there - it was. The thought of putting on white satin panties, white lace top hold ups and my black slip was making me so hard and wet. I was desperate to the point of almost shaking with anticipation of displaying myself in the toilets for men. I regular use another toilet in Malvern to get dressed in my lingerie , as it means I can hit the ground running once I get to the more secluded seedy toilets I like to play in. I parked up outside my changing room toilets and walked in with my carrier bag of undies. No one was in , so I quickly made for the cubicle and started to change. Just as I was finished dressing , I heard. The outside door open - some one was coming into the toilets. It was starting to get dusk outside and the lights inside the toilets were not very bright. I heard the door open for a second time and thought the person must have left having done their business . I pulled on my jogging bottoms over my stockings and put my shirt on over my satin slip -provocatively my black slip was quite evident under my white shirt but I guessed it didn't matter as it was getting dark outside and no one would notice. Still buttoning up my shirt I open the cubicle door to see an old bloke in his 70s stood at the urinal with a young girl of about 20 stood behind him with her arms around him clearly wanking him off into the urinal - they hadn't noticed me so I stopped buttoning up my shirt and stood watching them . Quietly I moved over toward s the girl who had her back towards me. I then sternly said" what are you doing !" They both turnaround and looked very shocked . The old man had his cock hanging out with a semi errection whilst the girl bowed her head in shame. I asked again what they were doing and the girl started to protest her innocence. Claiming the old man made her do this for him " I could inform the police of this" I shouted at them , " what do you think they would do to you both ??" The old man begged me not to do that whilst the girl started to cry feeling a little nasty at upsetting them both, I said " perhaps we could deal with this in a different way that would stop the police getting involved " both of them seems receptive to an alternative. " how about you finish what you were doing to him" I said to the girl," and I will watch ". She wasn't sure but eventually she realised she had no option- the old man didn't protest at the suggestion. " Go on then, continue to wank him as you were before I caught you both" With this she reached his now limp cock and started to wank his shaft . "no,no !" I said after a few minutes of her wanking his still limp cock " you are going to have to do more than that to get him hard" I said . "Get on your knees infront of him and suck it" she looked shocked but realised I was in no mood to compromise what she must do, if I wasn't to inform the police of her antics. With that the old man turned away from the urinal and she went down on her knees and started to take his cock into her mouth. She protested a little, but I grabbed her head and pushed it down so she took his entire length. By now his cock was getting hard. As she continued to suck him I was found myself starting to slip my hand inside my shirt and feel my hard nipples through the black satin slip - the old man noticed this and smiled at me " are you a crossdressers he said ?" "Shut up and enjoy having your cock sucked"I responded . He smiled again and said "crossdressers really turn me on, I use to love coming to these toilets and picking up a younger sub crossdresser and playing with them" " but I'm not sub " I snapped at him . " really ?" he said , "show me what you are wearing!" I started to undress , doing exactly as he demanded , taking off my shirt and then slipping down my jogging bottoms to reveal my lingerie . "Nice " he said as he reached over to me and pinched my already hard nipples through my slip. This had the desired effect of making me totally sub to him. "He recognised this and said " now who's in control ?" I didn't answer, so he pulled on my nipples harder and repeated the question" well slut, who is in control now !" My only response I could say was " you master" . How the tables had turned In a few minutes .. .... With this he pushed me to my knees next to the girl and said "now you will both suck my old cock!" The girl withdrew her mouth from his shaft and offered me his cock , which I slipped into my mouth. His cock was salty and had a faint odour of piss . Whilst I continued to suck his cock , the girl wanked it into my mouth whilst her other hand started to explore my satin clad body. She appeared to be protesting no more, but actually enjoying it. Before long her roaming hands were stroking the front of my panties with my cock straining against the soft shiny material . I could feel drops of pre cum filtering through the lace trim of the panties at the front . She leaned over to me and whispered in my ear that she found crossdressing of blokes very sexy. The old man pulled my head away from his cock and said " Jane ( the young girl) and I are not complete strangers you know , we come here often for kinky fun- we saw you park up and come into the toilets. We knew from you carrying the bag and the time you took to come out that you were probably getting dressed in lingerie. That's why I said to Jane that I would go in first and then she would follow once we knew there was no one else other than you in here" So they both had this planned all along ........ Jane then spoke up" should we take this crossdressing sissy to your flat around the corner and have a bit more kinky fun with him ?" The old man nodded, "I think we should Jane , I am feeling very turned on now " They stood me up, and told me to get dressed and then lead me out of the toilets into the darkness outside. I followed them around the corner to a front door. The old man unlocked the door and pushed me in. Him and Jane followed. To be continued ( mail me if you are interested in what happened next)
