My wife Carla looks like any ordinary, suburban woman. She's 28, just over 5 feet tall and 115 pounds, wavey light brown short hair, full lips and big dark eyes. After having two children, she has a very nice curvacious body. She has what I would consider an above average sex drive but usually within the boundaries that most women set or have established for them by society. We live in a small, relatively conservative community, but that doesn't usually stop Carla from dressing attractively, sometimes in a very revealing fashion. One day, she called me at work and asked me to come home an hour early because she had a surprise for me. She said she was nervous about it and hoped it was what I wanted. She said to be very quite and to come through the back door of our house and to slowly walk towards the livingroom without saying anything. I followed her instructions in hopes the surprise was what I had hinted for. It was. There on the couch was a guy we both knew and liked, Mike, from a business we deal with often. Mike is about 30 years old, and very well-spoken and well-dressed. He's educated, physically fit and has always had a little twinkle in his eye for my wife. Carla was parading around the living room preparing some finger food and mixed drinks. She was dressed very casually, however, in jeans and a shirt and seemed to be pretending that this was a half-social, half-business meeting. When she finally saw me staring from behind a doorway, she winked at me as to say "Is this OK?" I winked back that it was. I later learned that she didn't want to dress too suggestively just in case I nixed the whole thing. Their conversation was a little tedious as I was anxious for Carla to change the tone and make a move. But after about a half an hour, Carla inched her way closer to Mike on the sofa and the conversation got more personal. At one point, Mike joked about something and momentarily placed his hand on Carla's thigh as people will do at times. When he went to remove it, Carla grabbed his wrist and placed it back on her upper leg and said something about people should touch each other more often. This was it -- the beginning -- and all of a sudden my heart jumped. Less than a minute later they embraced and began kissing. Mike reached under the back of her white shirt, exposing her back to me. He stopped for a second to say he was concerned about me showing up, but Carla reassured him it was OK and reached into his crotch, through his pants then climed onto his lap while still kissing. It was happening so fast. My blood raced and thoughts of interrupting came to mind more than once. Mike now slipped his hands down the back of her jeans. Then he broke from the kiss and unbottoned her pants while Carla removed her shirt. She took off her bra and Mike began immediately nibbling on her tits. A few minutes later, she dropped to the floor and pulled off Mike's pants and underwear to expose a massive cock that I am sure she wasn't expecting. There was Carla, bare-chested, with her jeans dangling around her ankles and panties pulled up her crack by Mike who tugged on the material as she swallowed him whole. All of this occurring within a few minutes of Mike touching her thigh and it was astonishing to watch Carla perform. Mike laid back, continuing to tug on Carla's panties as she rocked back and forth with his cock plunging into her mouth. The panties looked like a thong now. My wife then began reaching back and frantically played with her swollen pussy. She occassionally gagged on Mike's cock but worked it hard. She really looked like she was enjoying the challenge and exhibition of it all. Eventually she stood up and removed her panties. Mike guided her back down to get on all fours on the floor so that he could begin eating her pussy from behind. She was facing me and I could see her every expression as this man worked his mouth into her from the rear. She kept throwing her head back, and sometimes gritted her teeth. A few times we made direct eye contact, but I had to be careful not to be spotted by Mike. Carla dropped to her elbows and perched her ass up high. Mike was still rock hard and asked if she was ready. Carla yelled ,"Go ahead give it to me, just give it to me hard and fast." Mike positioned his cock to enter my wife from the same rear position which was great since I could see that initial expression of pleasure on Carla's face. As he worked his way in, Carla gasped and pounded the floor with her fist. Mike got hold of her hips and pulled her farther onto him. When he plunged all the way into her, Carla let out a scream, then began getting into the rhythm of the act. They screwed in that position for a few minutes, then Mike leaned back and Carla kind of went back with him as she now almost sat straight up on him, still facing me. His hands were all over her tits and I could see how erect her nipples were as he pinched them. I could also see his cock sliding in and out of her from this position as she rubbed her clit. She continued to moan, perhaps more than she has with me, and rode him for a few more minutes. In a few moments he was sliding his cock out of her and as he did so and spreading her ass open wide. He sat there and gazed longingly at the wide open ass, and the juices glistening on her lips and on his prick. Then he began shoving his cock in hard and deep, knowing that she liked that. Carla liked his words too. "Dirty whore! Sleazy bitch! All you want to do is fuck cocks! Right? You just want to lay around all day with your legs spread open and screw." The more he talked dirty to her, the hornier she got. She couldn't hold back the first shattering, splendid orgasm, the first of many she knew she would have before the day was over.... He began to thrust deeper and harder and faster as he humped on her and she pushed back against his pistoning cock. At the same moment, a crescendo of animal pleasure enveloped both of them. He filled her pussy with his cock juice, and covered her ass with his cum and then he was done. Afterwards, Mike left and I was able to come out of hiding. I had this need to physically and emotionally inspect Carla. She had put her panties and shirt back on. But I was so horny that I almost immediately removed them while asking her questions about how it was. At first she was reluctant, but there was no denying that she really liked it. She said she got off on the performance aspect as much as the physical pleasure. I saw her pussy still damp and raw and traces of cum in her hair. As I fingered her, I could tell that she had just had something massive inserted into her. I fucked her on the couch to see how she'd feel on my cock then finished, by coming in her mouth as I rammed my dick down her throat while she threw her head back over the arm of the sofa. She swallowed all of my cum and sucked out the last drops.
