I have an old pair of comfy pajama bottoms that I would wear in the morning around the house if someone was staying with us. The button on the fly fell off and it stretch out a bit over time. The result being that I accidently flashed several family members and friends my cock. My wife asked me to quit wearing them, in fact I had thought that she got rid of them.

Turned out to not be the case. My wife's recently divorced sister came to visit. That evening I left them to visit, going to bed to read. After a few drinks, they had gotten a bit loud with their talk and laughter. I caught bits and pieces of my wife talking about my cock. She seemed to be teasing her sister, there is a bit of conflict between them, thus was not going to turn into any sort of swing opportunity.

The next morning as we got up thinking about breakfast, my wife handed me the previously banned pants. I made breakfast for them, telling them to just relax and talk. Sister in-law was seated in good chair to watch me cook. I made sure that my cock was exposed from various angles for her as she stared.

After breakfast, I took their plates. My wife made a small gasp bringing to attention that they could see my cock. I apologized stating that I would change. Sister in-law quickly assured us that she did not mind. In response my wife pulled my cock completely out for her to view. She stroked it a bit and sucked it until I stood at full staff. Then we went into the bedroom and fucked with my wife being extra loud for her sister to hear.
