Sarah and I excused ourselves to change into our swim suits and soon I emerged with trunks looser than Clydesdale and Sarah in her new one piece black...suit with white stripes across the bosom. Avril had got us two beers and we chatted nonchalantly as we sipped the booze. As usual Jim was grafting at his chartered accountants, job though it eventually emerged he,d been having a torrid affair with Avrils, sister Carla for months. I suspected Sarah and Avril had been doing a bit if lesbian fun,. As I approached our bedroom,I could hear the unmistakeable sounds of my wife moaning,and also the sound of flesh slapping flesh,my heart was going like a jackhammer as I peered through the not fully closed door. What I saw was so erotic,she was riding someone,i couldnt see his face,but I could clearly see a very large cock goin in and out of her pussy she would lift slowly up then all the way down again so you couldnt see all of it,but when she was at the top of her ascent there were a good 8. She looked at Frank and winked and wanted him to rest- and as she left she asked me to keep Frank ready for round 2. Frank grinned and so did I but I immediately looked at his glistening cock and knew that it and he needed attention. I reached and found his wet cock and stroked and then went down and took his semi erect cock in my mouth and I could feel it pulse and grow in my mouth ....I loved tasting Dana on his cock and Frank gently grabbed my head and held me there to service his great. Then I smiled and said "Can't wait." "Wait, I need to check your ID" Why does it matter?" I asked. "Because we have to confirm it's you and that you're over 18. Without that, this doesn't happen." What, now you care? Fine. Here."He looked at my ID for a minute and then said, "We have a nice space for you" and pointed down the hall. I walked past all four guys, strutting my stuff. As I walked I tried to figure out who each was. I saw a young k** and thought for sure he was the tiny one. He was.
