My wife; Rose and I lead a rather ordinary life. Not much out of the normal, work, dinner, TV, and the occasional social activity. We have been married for seven years now and have two kids. Our sex life is a true reflection of our every day life, normal. We have a small circle of friends, most of them have kids the same ages as ours. We meet with them often for picnics or other activities that revolve around the kids. There is one particular family that we are really close to; Eddy and Samara. On many occasions they would come over for dinner, and rather than drive back (particularly if they were drinking) they would just sleep in the spare bedroom. Some months ago, I started to notice how sexy Samara was, particularly in her nightgown.

During one summer night, when they were sleeping over, she wore a short, silk nightgown. This certainly helped highlight her curvy body. After all, she had firm breasts, extremely small waist and an ass you die to get into. The way she swayed her hips when she walked around the house that night gave me a hard on almost impossible to conceal. At that stage of our relationship, I never even considered doing anything but look and enjoy the view. Sometimes I would jokingly pinch or pat her bottom and then spend the whole night thinking about it, so firm and perfectly rounded.

One night, my wife and I managed to put the girls to bed early, and we decided to have a quite romantic dinner at home. We ordered some food from the nearby restaurant and asked for it to be delivered, meanwhile chilling a bottle of white wine. We went through dinner and the wine relatively quickly. My wife had more than her distribute of the wine. We cuddled next to each other on the couch to watch TV. A few minutes later, Rose’s hand was inside my shorts, fondling my already hard cock. We decided at that point to go into the bedroom and close the door, in case one of the girls woke up. On the way to the bedroom, I stopped by the bathroom and picked up the bottle of massage oil from the cabinet. When I got to the bedroom, Rose was lying on the bed face down, completely naked with her legs spread. I quickly undressed and sat next to her. I opened the bottle of oil and poured some on her back. I slowly gave her a back rub venturing down with every stroke towards her ass. I then poured some more oil on the top of her ass crack and spread it all over her cheeks and on her asshole. Every time my fingers touched her asshole, I would sense her breathing in heavily in anticipation. We had never had anal sex in all the years of marriage we had, so the idea was really exciting to me. My cock was hard as steel thinking of the possibility of fucking my wife’s ass for the first time.

I slowly inserted one finger in her ass and started to move it in and out. I then added a second finger to it, and could sense that it was a bit uncomfortable for her. I was too excited to even consider stopping, so I just kept my two-finger assault in her ass. After a few seconds she relaxed a bit and I could freely move my fingers in and out of her ass. At that point, we both knew what was coming next. I pulled my fingers out of her asshole, moved my hips closer as I kneeled between her legs. I reached under her hips and gently raised her into doggy position. I grabbed my cock in my hand and very slowly guided the head into her asshole.

My wife cried out softly with pain but it was too late to try anything as the head of my cock was well past the sphincter muscle of her asshole. I held my cock steadily there for a few seconds before I proceeded to shove it the rest of the way in. when it was completely buried in her ass, I left it there for a while, enjoying the warmth and tightness surrounding my cock. I then started to slowly pull it out until only the head remained inside. In no time at all, I was fucking in and out of her ass like a mad man. She was responding by pushing back to meet my strokes. I could feel her getting closer to orgasm, so I waited until she was cumming before I let myself go, flooding her intestines with my sperm. We layed there for a while before getting up to wash and go to sleep. Lying in bed afterwards, I could not help but imagine what it would be like if it was Samara’s ass that I was fucking. I fell asleep with a smile on my face.

The following day something happened that changed the entire nature of our relationship with each other and with Eddy and Samara.

My daughters and theirs were all invited to a birthday party for the son of a mutual friend. Both my wife and Samara decided to drop the kids at the party and come back to our house to spend the afternoon until the party was finished. Eddy and I agreed to meet them there after work that day so we could spend the evening together.

I had spent most of the morning thinking about my wife and what we had done the night before. I could not concentrate on my work at all, so halfway through the afternoon, I decided to call it a day and head home. When I got there I noticed that the living room curtains were drawn shut. This was unusual, because we only shut the curtains at night. I did not make anything of it. When I tried to open the door, I was surprised to discover that it was locked. I used my key to get in, making as little noise as efficient to understand what was going on. As soon as I walked into the living room, I saw something that mesmerised me on the spot.
