I still don't know why I didn't tell my wife I would be home from the business trip 2 hours earlier than expected. It wasn't like I didn't trust her or was trying to catch her out. It just slipped my mind, and I ended up pulling onto our driveway two hours earlier than expected.And it was definitely earlier than she expected because someone else was parked on our drive. She definitely didn't hear me come in because as I came upstairs, there they were, well and truly enjoying each other's bodies. It didn't take me a second look to know there was no way I could compete with him in the size department. So I did the only thing I could, I watched until they were finished, didn't say a word, and then carried on as if nothing had happened. That night after she took a nice long shower, I knelt down in front of her.But that wasn't the worst part! The worst part was that I loved it! I loved catching her with another man, and savoring their combined taste. And if I'm honest I don't think I hid my arousal too well, and deep down, I think she knew that I knew because she soon started taking this to a whole new level.
