I’m Finding Out More About Her

We have been married for 20+ years and my wife is opening up and talking about her past experiences and there is a new development.
Her and I have talked about what we think about having sex with someone else or even role playing acting like someone else. I always feel like I’m dancing around issue because I am actually turned on when I think about my wife being pleasured by another man. Whether would actually enjoy it, I don’t know. But she always acts like she is not interested in that or that she even thinks about other men sexually. (I’ve told her that it is only natural for at least there to be a fleeting thought about someone else) but she always acts like she does not really think about that.
But in the last 4 or 5 months, I’ve noticed a few things around our house. Lately I have found the vibrator in the shower and I won’t say anything and I will just put it away. I did ask her one time if she was using it in the shower and I told her I thought that it was hot that she did, but she said no, she was only cleaning it. Lol.
But, the most recent development is when I decided to come home for lunch one day. She gets to come home for a couple of hours in the middle of the day for her job so she is home every day between 12 PM and 2 PM. I was going to grab something else for lunch, but at the last minute, I decided to come home.
I came through the garage door and was not really quiet about it but she was very preoccupied. She didn’t hear me. I could hear her in our bedroom and at first I was a little worried that she might be having a panic attack or something because she was breathing so heavy. But as I got closer, I realized that it was the sound she makes when she’s having sex. So I quietly looked around the corner into our bedroom and saw that she was straddling some kind of dildo that she had set up on the floor. She said maybe three or four other dildos on the floor next to her. But she was fucking that dildo like her life depended on it. She was totally naked and looked crazy sexy. Her back was to me so she couldn’t see that I was standing there. I just stood there, looking around the corner watching my naked wife have her way with that dildo. Which really funny about this is that I did not know that she had any dildos. She has several vibrators and I’ve asked her several times if she wants dildos, but she always says that, she doesn’t like the idea of even thinking about somebody else inside of her. Even if it’s just a dildo.
It was hot watching her fuck this dildo but what was the cherry on top was that she started saying a particular name. This is a common name and it could’ve been one of three people. But, one is our older neighbor, which is not a very attractive man, One is our insurance agent, which is a decent sort of guy, but I wouldn’t say he’s attractive. The other guy that has his name is a coworker of mine. That is about 10 years younger than us. He’s married and has three children, but he is in great shape And she does see him sometimes when she comes by my office. She kept yelling the name and telling him that he was fucking her so good. I decided to go back to the car and open the garage door again and call her so that she would not know that I was there.
When she answered the phone, I told her that I was just getting home and that I was in the garage. I told her that I had to check the mail first, and then I was coming inside. This gave her time to clean up and jump in the shower and act as if she was just taking a shower.
I cannot stop thinking about all of that and I have to say that I am extremely turned on.
