As soon as she mentioned her desire to try a BBC GB, I made it happen. Took a month to set it up, and she was a bit nervous--we walked into a hotel suite in which 12 naked BBC men, complete strangers, had a naked woman on a bed and were fucking her tag-team (4 at a time)..we sat on a sofa (the deal was 'we were there to watch') for about 20 minutes watching, when one man walked up to my wife (with his erection in her face), took her by the hands to stand her up, then slid her dress over her head (she never wears panties, and I made her leave the bra off to better show her 38I tits). He led her to the bed, pushed her gently down beside the other woman, and put his face between her legs--as another cock was rubbed against her mouth until she opened it, and a cock was placed in each of her hands. 20 minutes from demurely dressed to four strangers making her service their cocks. Then the guys switched and a cock was shoved into her pussy--which was dripping wet--until she orgasmed (about 60 seconds). After 10 minutes and her dozen orgasms, he took a rest and another cock entered my wife's pussy--by then she was sucking eagerly on whatever cock was rubbed against her face and reaching out to rub the cocks waiting their turn on either side of her.
The other woman retired to a second bedroom with a couple of guys, and the evening continued for a couple of hours (with phone calls being made to get fresh 'talent' to show up as she drained each cock on her tits, in her pussy, down her throat.
