We decided to put an ad in a national "mens mag"for guys who were interested in watching an attractive couple fuck in their home.A few days after the ad appeared the fon went ballistic,but we were especially keen in an older man watching us and chose a guy called Ken who was 57 and seemed genuine and kind,with his own home.Gaynor had bought some foxy new undie for the event,a silk red basque no cups,50s seamed nylons,and proper stillettos,a skimpy string,worn under a long dress,how I never shagged her on the way there I dont know as it was a good hours drive When we got to Kens we were pleasantly surprised,nice bloke and detached house so she could squeel as loud as she liked.The arrangement was for him to watch us and wank while we did it,no touching,no fucking. Ken got us a glass of bubbly each,and I put a music tape on so Gaynor could give us both a show before she was fucked.She started by strutting around us wiggling her arse in our faces and turning to unbutton the front of her dress,pulled it to either side of her titties,and bending to put them close to our faces,teased her nipples until they stuck out like raspberries.She turned and pulled the hem of her dress up to show her seams all the way up above the tops before letting the dress fall to reveal the "ensemble"-Ken gaped at her fantastic tight arse framed between stocking tops and basque,and when she bent we could see her full cunt lips through the nylon G-string.She was still swaying and bumping to the music and put one foot on the arm of his chair gyrating her cunt,as he stroked his cock, then turned bent and slid them down to give him a full view of her. I was down to my boxers by now with an aching hardon,and Ken begged us to get on with the action.I layed her on her back on the floor and went straight for a 69 dipping my dick in her mouth,while I tried to suck at her clit,but couldnt get deep enuff,so we rolled over with her on my face wanking and sucking each other while Ken observed us from every angle and encouraging her to be a dirty slut,and asking her how she liked teasing his cock. mine was dying for cunt so I slid her off my face and onto me almost in one motion,and she was face to face with Kens cock almost in her mouth.she was fucking me,teasing her tits and pussy,moaning louder and louder,and then,bang,a massive cum shot through her and she started to fuck like a train.She turned round and squatted over my dick so Ken could get a great view of entry,then kissed my cock several times with her cuntlips before impaling herself- another orgasm ripped thru her.Ken was beside himself with dirty comments about her arse, cunt, and tits;when against the rules he shot a full load over her butt,she yelled and I fired both balls full of cum up her.Ken wanted to see,so she raised herself of me to let it run out onto me which he loved.We relaxed with a glass,and a movie of her,before a little more action-but thats for later.
