We have been swinging now for two years. Being bi as I've always said to Kath means I get the best of both worlds. She has always endulged me and gone along with most things, mmf, mmmf. She has never allowed me to play with another woman and to be honest I'm not really all that bothered. we have a sub Dom relationship, I am the sub. We have talked about gangbangs, bukkake and dogging, and I've always said I would love to see her filled mouth, cunt and ass dripping cum so that I could lick her clean. I love the taste and feel of other mens cum , dripping out of her cunt and ass, and on her skin. The mixture of cum, cunt juice and sweat really gives me a buzz. Kath is 5'8'', size 16, 38c tits, shaved cunt, and she's attractive with shoulder lenght hair, and is curvy. She sucks cock as if her life depends on it and swallows, the only thing she won't do is pain. That said she likes her ass smacked and her hair pulled. We had been out to Frome to meet two bi guys who turned out to be a no show. We had releived some of our sexual tension with a quick but were still as horny as hell. We had wanted agood session as it had been a while since we had last played. She was telling me how horny she felt and that she had wanted to see me spit roasted by the guys. As we were south of Bath and passing through to the M4 I jokingly said, 'Well we're passing Tog Hill and thats a dogging site and there's another place nearby. Are you up for it?' Kath grinned and replied, Will you take two cocks if I am?' I simply said,'No problem, you know I like cock.' As we passsed throgh Bath I had to stop for petrol, Kath said she had a few calls to make and I tanked up and went to pay. When I returned she was all smiles, I took this to mean she was happy with our prospective adventure. We left Bath stopping for a cup of tea. Half an hour later we approached the turn to Tog Hill i asked her if she was still up for it. She said she was so we turned off the road into the car park. I selected a quite spot and waited. There were a several cars dotted about with single guys in them. Doggers come in all shapes, ages and sizes. As we waited I pushed her short skirt up over her holdup stockings, pushed her legs gently apart and began to play with her juicey wet cunt. She laid back into her seat, pushing her hips forward. She moaned as I slid my fingers into her. Her skirt had risen over her hips. My cock was straining hard against my trousers so i got it out ready for her to play with. I pushed her top up revealing her lovely 38c's. Kath's nipples were rock hard. I licked and nipped at her tits, all the time fingering her cunny pushing two, three then four fingers deep into her. As I fingered Kath I pulled her head down on to my cock so that she could give me a BJ. Kath knelt on her seat taking me deep into her mouth. Her kees apart, ass toward her window as I played with her clit and tits. I noticed that two guys had arrived and were standing by her window and a few more were in the shadows. They had a full view of her ass and cunt as her head boobbed up and down on my cock. I told Kath that she was being watched. Her response was to sit back in her seat put her feet up on the dash and spread her legs as wide as possible and begin to finger herself. Her body was on full view, her cunt glistened with cunt juice her tits and nipples hard and her fingers played deep in her. She told me this is what they want so let them see and took her top off. the guys were wanking furiously. She wound her window down and began speaking to them. She told them That we were there for cock and we both loved drinking cum. hands played with here tits, squeezing and tugging her nipples. She told them she was in slut heaven and wanted everything they could give. Kath's Dom nature surfaced and she told them that as her slave I would do as she wished. I was then told to get out of the car and strip off. She told me to do so ten yards to the front of the car so that she could see my embrassment and that she wanted to talk with the boys nearby. It was only as I got out that I realised there were 8 men there and most had their cocks out and were wanking. I undressed slowly, I watched as she stepped out of the car wearing nothing but holdups and heels. The men crowded round her and began to touch her all over. Fingers explored every orifice, hands grouped her tits, she was laughing and talking to them. My slut Mistress was enjoying herself. She pointed to me and told me to go fetch a couple of blankets from the boot. Getting into the role, I said, Yes Mistress' and ran to my task. When I returned she told me to spread them on the grass and kneel down with my mouth open. I did as commanded. She came over to me told me that she was going to have a cum bath but that I was to suck each cock hard before she used it and to clean them after. Also she had a treat in store for me later. Kath told her new friends that she enjoyed watching me gag on cock and that they may use me as they wished. From that moment on cock after cock was forced into my mouth. Kath sat back watching then she told them to come to her and use her as a total slut in any way they wished. A big guy pushed to the front and said suck it slut. He pushed a thick 8 incher into her mouth and began to ride her face, she had a cock in each hand and was wanking them hard. Hands were pawing her body, pulling her legs wide, tugging her nipples. Fingers pushed deep into her as each vied for a chance to grope her. With a gasp the guy fucking her mouth released her hair and shot a thick stream of cum into her mouth and over her face. His cock was replaced by another then a second guy joined him, saying she could take two cocks in her slut mouth. As I watched her tongue flicked over the heads of these new cocks, then she took both and was face fucked. The guy who had first face fucked her came to me pushed his cock into my mouth and telling me to get him hard. The salty taste of his cum was lovely as I licked and sucked his cock and balls. he said I'm going to fuck that dirty slut in every hole, you can lick my cock after I've used her dirty ass. Kath was awash with cum as cock after cock shot over her face hair, neck tits, it dribbled from her mouth down over her chin. I was cleaning their cocks and getting them hard as fast as I could. The big guy took hold of Kath by the hair and calling her a whore dragged her onto her hands and knee's so that I had a side on view of her. Facing me she said to him, 'Fuck me as you want, I'm your slut'. He looked at me and said,'This is how we treat a whore you wimppy excuse for a man'. She was laughing as he pushed his meat into her. He began to fuck her with hard long strokes, I could see his cock glistening with her juice, he was cheered on by the others. He pummeled her cunt I could see the marks his fingers made on her hips has he dug them and his cock into her A cock was shoved into her mouth and she was pushed hard onto it gagging as he drove deep into her. Pulling out he told the others to use her as he had plans for me. Pushing me down onto my hands and knees he told the others to give Kath a clear view but to fuck her in every hole. As I knelt on all fours I did not know what was going to happen, calling another guy over he told him to face fuck me. A few guys had fucked Kath by now and her cunt must have oozed cum, she was thier cum dump,he went to her pushed his fingers into her then came back to me, this'll do for lube, and roughly pushed a cum smeared finger into my ass. 'Hope it stings bitch because by the time we're finshed you'll be gapping like your slut wife'. He pushed his cock into me with no attempt at finesse making me cry out with pain. He told the other guy to hold me tight then with cock filling my throat and ass began to pound his meat into me. The pain as he stretched and filled me was intense. Still he pounded away, riding me hard and fast saying to Kath, 'Is this what you wanted to see slut?'. She replied breathlessly,'Fill him with cum'. As Kath was fucked another slid below her and pushed his cock into her sopping wet cunt, she screamed DP me you bastards I want two cocks in me. Her cunt and ass were constantly filled, she was in slut heaven. All three holes filled and still they wanked over her. The big guy fucked me hard spunked deep into me I felt his hot spurting rush of cum. Pulling out he told the guy using my mouth it was his turn, then said lick your dirty ass juice off me. Taking his helmet into my mouth I licked our combined juice's from him as my ass was raped again. The taste of him, and my ass flavours was a heady wonderful mix, I was in heaven. I lost count of how many cocks I sucked, or how many fucked and used my ass. Warm hot cum dribbled from me, it ran down my legs, it filled my mouth and dribbled down my chin. Kath the slut took cock after cock, it seemed like we had been there hours. My body was scratched and ached but still they used us. Her stockings had cum on them as did her whole body. Dragging Kath round so that I could see her ass and cunt I was amazed at how much spunk dribbled from her. I watched as the big guy pulled her ass cheeks wide exposing her abused ass hole which gapped wide when he opened her. The dirty slut had been well used. He pushed her face down spreading her legs so that I could see her cum filled cunt. I was told to crawl over to her, I did as bid, he pushed my face against her swollen cunt lips ordering me to clean her out. At the same time telling the other to fuck Kaths mouth and my ass. As I licked her rounded ass, taking in the smells and taste of sweat, Kaths cum and their cum, my ass was fucked repeatedly whilst the others wanked over Kath and me covering us in a last shower. It turned out that Kath had been in contact with the big guy on SH and confided all her desires to him both on email and phone calls and that he was a regular at Tog Hill. She had phoned him when I had stopped for petrol and arranged it all. Since then we have been with Bill to a several other car parks that he knows. I am their now their bi sub fuck toy. I am used on a regular basis and do everything they wish and want. I am addicted to cock and rough use and do as I am told. We are happy in our roles. Kath is his slut and I am their slut.
