So many years ago still in the first flush of our marriage, me in my mid thirties her in her mid twenties were pretty wild. We partied hard and were edgy - we'd go out for dinner with groups of friends and fuck in the toilets sometimes quite loudly, it was a debauched time, the wine flowed and our large circle of friends all got on, we were high on life. It was late one particular evening, we were in a minicab homeward bound after a great party. My wife, lets call her Amy, always wore provocative clothing, really shorts skirts and minimal tops, not slutty or particularly sexy just not much material! Amy was sitting in the middle of the back seat and I started rubbing her tanned lithe bare thigh not particularly sexually at first but then my fingers got serious and went further until I could feel the edge of her panties - I worked my way round under the material and started stroking her pussy. Amy started to respond moving with the rhythm of the fingering - now, rather obviously her skirt had risen up and she'd spread her legs a little wider to assist my efforts. I looked up and the cabbie had no eyes on the road - he'd adjusted his rear view and was watching intently. Amy also had registered his interest and was playing to the gallery, she pulled her panties completely to the side exposing her inflamed pussy and then moved up, freed her tits from her skimpy top and was pinching one of her nipples for us both. At this point in a horse voice, rather than have him kill us all through lack of concentration I said 'find somewhere to park'. We end up in a deserted Country Park public car park. The driver finds a corner behind a wooden hut and parks up. Amy now has no pant un and is topless - my hand has disappeared into pussy which is sopping wet with her juices. Our Cabbie has his cock out in the front seat and is stroking himself off and cooing like a pigeon. At this point Amy pulls my hand from her pussy and puts it into the cabbies mouth - he proceeds to suck my fingers off which Amy finds amusing... whilst she releases my rock stiff cock and starts to wank me off, she turns and pull the Cabbie forward and I watch her whisper something in his ear next he exits the car, opens the rear door, pulls Amy along the rear seat towards him and starts to fuck her from behind - using her rucked up miniskirt to rock her onto his cock. She looks at me smiles and starts to deep throat me by way of compensation for taking this stranger's cock. With a moaning crescendo like a pornographic three Tenors I shoot my load into her mouth, Cabbieman cums in Amy's pussy, she's been having orgasms for the last half an hour...and is screaming at him to ' fuck me you bastard fuck me', we all collapse spent. Searching for clothes discarded in lust were on our way again a spent silence in the cab whilst we digest what just happened. It's late, the sitter is on serious overtime, I hug Amy all the way home until we arrive on our drive, he smiles at us and says 'It's all good - I've been paid'....
