Revealing my secret

My wife and I have been married a number of years. The past several years, we have decided to open our marriage to other partners. It was my idea. I told her I wanted to see her with other men. She thought about it and due to my work schedule she thought it wasn’t a bad idea because there have been several times that she was horny but couldn’t do anything about it because i wasn’t home. I told her I had no problem with her sleeping with other men so long as I could watch and sometimes be apart of the sex. She said that she wouldn’t want to watch me with another woman but she wouldn’t be mad if I slept with someone else.

So for the past few years, she has had a boyfriend. Well 3 boyfriends in 4 years. Her latest boyfriend she’s been with for over a year. I’ve asked and she’s said that they have sex usually twice a week but sometimes as much as 5 times a week. I’ve watched and jacked off to them fucking countless times and we’ve had three ways several times.

My wife has met my girlfriend but hasn’t see us have sex because she said in the beginning she didn’t want to. Cassie and I have been together for 3 years now. We work together. I wasn’t specifically looking when I met her but it’s just happened. The thing is…Cassie is a trans woman. You wouldn’t know it until you saw below the belt. She has had a lot of surgeries but she is gorgeous and my wife has said so.

Then about 4 months ago, my wife asked me when the last time I had sex with Cassie was. I told her it had been just the day before. She said, “She’s gorgeous. You aren’t gonna leave me for her are you?” I said, “You have something she doesn’t, dear.” She said, “Our love?” I said, “Of course, but that’s not what I meant.” She said, “Then what?” I said, “Cassie has a dick. She’s trans.” She said, “OMG are you serious? You need to have her over immediately.” I said, “Why?” She said, “Cause I want her. You need to share.”
