It didn't take long for a few glasses of wine to make the atmosphere very convivial between us and for the banter between MG, Richard and Jacqui becom... full of sexual innuendo once Richard had twigged as to what was going on in our lives away from work. There seemed to be much conspirital whispering going on between MG and Richard which, at the time, I gave little attention.During a lull in the after-dinner speeches MG took Jacqui away to the ladies restroom for them to return a short while. She took my cock in her hand and fed the entire length into her soaking wet hole. Then without prompting, reached back to massage my balls while grinding her hips back and forth.”Oh god, I’m close! I’m so close,” she gasped. “Your cock is so hard.”Though she always seemed to enjoy hearing it, my wife had never been one to talk mug during sex. Whether she was faking for my benefit or really into the moment, I couldn’t have cared less. I took her naked ass with both hands and matched her rythym,. Where the four halls intersected above was a large chamber down here. There was a stone pedestals with a crystal dome over the top.I looked around the barren room and looked at Kate and she trembled and gestured, "remove the crystal dome."I moved closer and tried to look through it but there was not enough light. I lifted it and bent to set it down before I stood. I looked at Kate as she swayed and then looked at the huge diamond shaped like a double pyramid. I caught her and pulled her back,. And after you two are done there’s something else you need to do for me but I’ll leave that till later. Shari, I think we should show him how serious we are, go ahead, you know what to do.” On that cue Shari pulled off her top revealing her perky little breasts with big, dark nipples. The shoes went next then she loosened her skirt and dropped it to the floor. Staring straight at me her hands went to her narrow hips and slowly pulled down her lacy white panties which she quickly stepped out of.
