We sat silently for a few moments, not sure what to do next, when Tracy broke the silence, “Can I join you?”“What!?” I said, my eyes wide with... surprise.“Would you mind if I joined you?” she repeated.My mind started racing. Was I dreaming, did my sister just ask if she could join my wife and me for sex! This was just too amazing to be real, surely not. My dick, which had lost its erection at the unexpected sight of my sister, was now rock hard again. I glanced over at Zoe, but she said nothing,. "Okay, well Johnny is waiting for me on the dance floor. Want to come?" With that, the duo moved through the crowded hallway into what was usually the dining room of the house. They both froze as they reached the doorway.As if it was no big deal, there was John, dancing with another girl, grinding up against her ass as he did so. "Oh! Thanks for the drink baby!" he called out as he noticed the two enter the room. He walked up to them to accept the booze-filled cup."Are you fucking kidding me?!". The whole bar crowded closer and closer around us and I was surrounded by the surprisingly-heady smell of alcohol and sweat, which only heightened the atmosphere. Still, I was nervous, shaking all over as I lay there, a taut and expectant sacrifice. Some sort of participation was clearly very soon going to be expected of me and I didn’t know how far it would go, how I would react. During his show he had stayed close to me all along, a touch here and there as he was doing his work. Now he. It was one of those glances that shift way immediately, only to come right back again. By then she realized that she had been caught looking. Instantly, I wondered if Id caught her looking, or if she had just reeled me in with her incredible eyes. It didn't really matter. There was nothing left to do but pursue the eyes and whatever was behind them.My place at the bar was a regular one. I was regular too. The routine was always the same; cabernet, very rare steak, baked potato, and my favorite.
