At around 11.30 most nights I often walk the dog through a local park across a cemetary, skirt the town centre and then back home along a canal path. Its quiet and normally I dont bump into many people along the way except on a Friday and Saturday night when the park becomes a bit of a low profile dogging area as lots of couples use it as a short cut home after a night out in the town. I've had a few encounters in the park, lots of watching, a few handjobs a couple of blowjobs and a shag from some nice tottie usually at it with their partners. One Monday night towards the end of last summer, I had a chance encounter that I will never forget, my wife was in bed watching tv and I shouted up to her that I was going to take the dog out and wouldnt be long, she murmered something about her being asleep when I came back, typical I thought as I left. As I entered the park my dog dragged me down the side of a toilet block which I usually try to avoid because years ago it was used as a meeting place for gays after dark, but I had never seen anything like that going on, the place that I was interested in was further in past the tennis courts around the gardens, pavillion and bandstand thats where all the action took place. As I stood there in the darkness next to the toilets waiting for my dog to finish peeing I heard the sound of high heels entering the park, I sank back into the shadows not wanting to startle the lady, but my dog barked at her and dragged me out of the shadows, she nearly jumped out of her skin, I appologised she hesitated but came over and made a big fuss over my dog,'i need a ciggy after that' she said as she put one to her mouth, I lit her up she took a few long drags and offered me one, I dont usually but took one, we got chatting and introduced ourselves, she was called Tina, we had a good laugh together about how we had just met and she was convinced I was gay lurking here so late, I promised her I wasnt and in my gayest voice I offered to walk her across the park and proceeded to 'mince' down the path, we giggled, flirted and fixed gazes on each other in the dim light she looked quite attractive I'd say she was about thirty, she had short dark hair cut in a bob style, dark eyes pale skin and great red painted lips, she wore a black jacket over a white blouse, a short tartan skirt revealed her gorgeous legs. She was very petite and even with the heels she was a lot shorter than me, she accepted my offer and grabbed my hand, I told her i needed to pee, and dashed into the toilet there wasnt much light in there just a dim light in the entrance and the distant street lights through the frosted glass, as my eyes adjusted I found the stall and started to pee, a strange hand grabbed my knob and sprayed it up the wall everywhere except into the toilet, I turned round and it was Tina she giggled and told me she had always wanted to do that, as I turned we grabbed each other and started snogging, our hands all over each other the chemistry between us was amazing and my cock grew at the thought of her. As we kissed, she wanked my growing cock, I undid her top and felt her small tits through her bra, she knelt and took my cock in her mouth I felt the tip hit the back of her throat her tongue licking the underside while her hands cupped and played with my balls. She was really good and within minutes, I told her to stop as I was going to cum, she carried on relentless, and I unloaded my balls down the back of her throat in four or five big squirts, she swallowed the lot. We kissed a little while we dressed, she went over to the sinks tidied her hair redid her lipstick, I came up behind her put my hands round her waist, one hand grabbing her tit the other pulling her short tartan skirt over her gorgeous firm bottom revealing stocking clad legs, and a little black thong, as my hand moved over the smooth skin of her bum I pulled the thong aside, got down and kissed her bum as she lent over, my tongue found her bum crack in the darkness the tip of my tongue entered her hole, she pulled her cheeks apart for me to get access. Just then we heard voices in the entrance, I jumped up and she pushed me back into the stall pulled the door over and told me to be quiet, I didnt know what the hell was going on but I guessed she knew at least one of the men and she seemed pretty pleased to see him, for all I knew it could have been her husband or boyfriend so I kept quiet and just watched throught the gap, one of the men introduced her to the other saying 'this is Tina my little cum whore, what are you?' she replied quietly 'a cum whore' he said 'a toilet slut aren't you?' she replied obediently 'yes, a toilet slut', he said 'your going to suck his cock aren't you?' again she replied 'yes'. There backs were to me and Tina was behind them facing me but through the gap in the door I saw her kneel down in front of them and she took turns sucking them both off, my cock was growing watching this and I couldnt resist undoing my trousers and slowly wanking myself, one of the men picked her up, bent her over the sinks pulled up her skirt and started to fuck her from behind they both took turns, they were quite rough with her but I heard her say 'harder fuck me harder' while she was being fucked the other took her head down to his cock and she sucked him. The man fucking her must have cum he slapped her arse as he pulled out and said 'fuck shes hot' the other got behind her and soon grunted as he filled her with his load, they both zipped up and left. I crept out of the stall when I was sure they had gone, she was still bent over the sinks with her skirt pulled up and her thong dragged to one side she was breathing heavy, my hand stroked her smooth bum, 'please fuck me' she whispered 'make me cum'. I pressed my cock against her bum and her hand came from below and guided me inside her, she was really tight but the cum inside her helped me slip in easily I fucked her hard, I reached underneath and played with her small tits while I screwed her, I was bursting to cum and my hand went down inside the flimsy fabric of her thong to rub her clit but I got a big shock all I could feel was a small hard dick and a pair of shrivelled up balls, I felt sick I was shagging a bloke up the arse, I had to pretend I knew already I was so embarressed so I wanked 'her' cock as my balls unloaded inside 'her' arse and pulled out pretty quick. She turned around and told me to kneel and open my mouth, hesitantly I did so I closed my eyes as she fed her cock into my mouth it tasted bitter and salty but my lips wrapped around it and my tongue flicked over the end, she jerked as she slid it in my mouth amd a small amount of semen dribbled from the end onto my tongue. I dont know why but I found myself kissing her again and she just said 'thanks' I asked her if we could meet again, she smiled and gave me her mobile number we got dressed and I walked her across the park we hardly spoke a word on the way, at the far side she gave me a peck on the cheek and said 'call me' we both went our seperate ways.
