Sarah was walking back from chelmsford station thinking how glad she was that it was friday at last, upon getting closer to her house and seeing that the lights were on and thinking, how strange as she dont remember leaving them on when she left for work! Key turns in the lock and opens to find Mark sitting on her sofa dressed in a dark flint grey suit and crisp white shirt, \" What the?\" Says Sarah, \" Hello hunny, just in time\" says Mark, \"time for what?\" Well your bath is run, with bubbles and upstairs on your bed is a new dress and underwear for you! \"why?\" says Sarah, \"I have a surprise for you \" says Mark, now quick before it gets cold. Sarah undresses and slips into her hot bubble bath and then takes the glass of wine from Mark, and asks \"so really, where are we going?\" well says Mark we are off to a big party in ingatestone. \" Great\" says Sarah. Mark sits and watches sarah slip on the hold up stockings, followed by a pretty lacey bra and then her new long black dress with a long split up the back stopping just below her arse! \"so, where are my new knickers to go with all this?\" she asks, Dont worry about those gorgeous, it\'d ruin the lines of that new dress! Mark and Sarah both slip out the house looking good and feeling even better and head of to the party. Pulling up and guy in a dinner suits parks the Mercedes while they head off into the huge statley home, Sarah still wondering what all this strange and unexpected night is all about! They walk into the bustling party full of couples ageing from 30s to 40\'s all with the men dressed smart and the women elegant but sexy! A few couples look round and seeing Sarah looking stunning with her tight black dress stretched across her impresive boobs, smile at her and nod a polite hello. \"Champagne?\" Says Mark, \"yes please\" after a few of those and a couples of hours walking round admiring the beautiful house, the party starts to flow and before long Sarah sees a few people being very touchy feely and over freindly for a posh party and finally the penny drops! \"What is this party all about then Mark?\" \"is it what i think it is?\" Yes says Mark, its a very high leval swingers party, couples only and we had to be approved by photo months ago, and accepted to get an invite, as they only invite good looking sexy couples. \"You ok with this?\" asks Mark, but then by the look on Sarahs face answers him, and the hand rubbing his hardening cock confirms it!
