Surprising I sat quietly. Contrite. My husband Bill stalked back and forth in front of me. Seething. He had every right to be angry. I don't know whether it was the red welts across my ass or my cum splattered breasts that angered him more. I couldn't imagine him anymore angry than he was right now. Earlier today I was baking for Bill's birthday. He loves chocolate chip cookies. I was surprised to discover that I was out of sugar, so I headed next door to Beth and Mike's. In the year, Beth and I have become fast friends - we talked about everything - and we have that kind of "open door" policy that good friends and neighbors often have. In the year they've lived her, Beth and I have become fast friends. We talk about everything, including sex. Especially sex. I thought I had a fairly complete understanding of Beth and Mike's sex life. I didn't. I crossed into their backyard and walked right to their kitchen door. I didn't knock, I simply opened the door and walked right on in. That's when I saw them. There they were, bent over the kitchen table. Mike was bent over the table, his ankles tied to the table legs. Beth was behind him. She was fucking him hard, really hard. Was the loud slap-slap-slap of her hips on his butt louder because of the leather harness she wore? A huge strap-on dildo, looking more like the business end of a baseball disappeared into his ass again and again and again. The strangest thought entered my mind, I wondered how long it would take Mike's asshole to return to normal after Beth was done fucking him. I should have left right then - they wouldn't have noticed. Even if they did notice - a quick "excuse me" and hasty retreat would have been better than what I did. I did nothing. I stood there and watched. Okay, I didn't exactly do just nothing: I touched myself to the rhythm of Beth's slap-slap-slap. Beth grabbed Mike by his hair and pulled him upright. He cried out and for the first time I looked at his cock. It was hard and seemed about the same size as Bill's. Moments later I watched his cum shot out onto the table. It was only when Beth disengaged from his ass with a loud pop that I made my presence known. I gasped in fascination at the way Mike's rectum remained open after Beth's withdrawal. Then I came, my knees buckling beneath me, and sliding to the floor. I returned home - clothes in hand, cum splattered breasts, and whip marks across my ass. If only I had returned a few minutes earlier. Bill was waiting for me. I should have been crying. I should have been begging for forgiveness. I should have been able to express some form or manner of coherent reason and explanation - some plea for understanding. Except I couldn't understand what had happened. "I can't explain it," I said to Bill. "Don't you move until I get back!" Bill warned. He stormed out of the house. At least I finally had some quiet time to think. I sat down and tried to understand what had happened. I've always had a very imaginative fantasy sex life. But my fantasies had always been just that. But today, I had nothing that could explain today. I could still see Beth walking toward me, that dildo pointing right at me. I was unable to resist, let alone run home. She took my hand and led me to the table Mike was tied to. Just like that I was tied by my ankles to the table legs and bent forward towards Mike. It was only when my breasts made contact with the sticky, cool cum on the table top that I realized I was naked. To say I was shocked when I felt Beth's tongue pierce my cunt would be an understatement. No less surprising was Mike pushing his cock into my mouth. I struggled against that until Beth started whipping my ass - with what I didn't know. Then I felt the dildo. Pressure first, then yielding, pain giving way to discomfort, then fullness - emptiness - fullness - emptiness - so fucking full. It went on forever. It took my mind off Mike's cock. My orgasm wasn't that big a surprise - there is a certain inevitable result that occurs with that much rhythmic, stimulation - that it was followed by more orgasms, each stronger then the one preceding was mind-boggling. I barely noticed Mike taking hold of my hair and lifting my mouth from his cock. Even as his hot cum spattered my breasts. Then it was over and I was just standing there, outside their kitchen door, clothes in hand. Now, sitting quietly, I replayed the scene a dozen times. The sound of the back door closing woke me from my reverie. I stared, dumbstruck, as Bill entered and walked very slowly past me, clothes in hand. He was stark naked. His cock hung red, limp and clearly spent. Instinctively I knew that he had fucked Beth - fucked her long and hard. I wasn't angry with him. He didn't say a single word as he passed. I turned, as much from curiosity as expectation. "Bill?" The red glow of his butt, the gingerliness of his gait, the drip of semen from the small of his back explained it all. "Bill?" I was still sitting where he had left me. More confused now then anything else. "Can I join you in the shower? Please?" He nodded. The hot water felt good and I actually enjoyed watching the remnants of semen disappear down the drain. Dried and dressed we returned slowly to some semblance of normalcy. Bill said nothing about what had happened to him and asked nothing further of my own experiences. Dinner was pleasant enough until Bill asked what I'd made for dessert. I remembered the chocolate chip cookies - and my quest for sugar. I stammered out an apology that entailed pointing in the general direction of Beth and Mike's place. Bill seemed to nod in understanding and we both sat silently for a moment. Bill broke the silence. "Mike said that he and Beth are hosting a party at a hotel downtown and they want us there..." Bill seemed preoccupied as he spoke. "They've invited us to a party?" "Not exactly." Bill looked toward Beth and Mike's. He paused again. "They want us to be the door prizes." My husband turned back to me and gazed deeply into my eyes. He smiled. "I said - We'd be happy to attend." I peed the chair I was sitting in.
