My wife Sarah had always fancied my older brother Andrew, she had nearly got with him just before we got together. She would always pass comment on his looks and his body, which he kept in excellent shape with a lot of gym work. At first I passed it off as nothing and just took the comments as nothing. Then one night we were in town on a night out and a couple of my mates were drunk and talking to my wife (then girlfriend). As I starting heading over she kissed them both on the lips, not much more than a peck but I was uneasy with the situation. As I arrived closer there was talk of tongues and they hadn't seen me arrive to the table but when they did the conversation swiftly changed.
We left shortly after and I still felt uneasy about what I had seen. However when we arrived back home I brought the subject up and started to feel aroused as she confessed they had asked her to kiss them and then they were trying to get her to make out with them both. I asked her if she was going to and she giggled drunk and asked me if i would wanted her to. I suddenly got so turned on and so did she and she confessed that she would of loved to of kissed them both and more. This then led to her also spilling the beans that she would love to fuck my brother Andrew.
These types of conversations became more frequent and started to focus on my brother. Until one night we were once again out in town and our group was all very drunk and dancing when I noticed my wife was dancing with my brother, obviously nothing overly suspicious but a bit of grinding and a few suspect placed hands I stepped off the dance floor to watch it develop. This continued for a while and I watched on highly aroused. We left soon after and all the way home she talked about it and how she had rubbed her hand on his cock and he was getting aroused and she said she felt what must be a massive cock through his jeans. When we finally got home her panties were already soaked and we had mind blowing sex while she said how horny he'd got her.
