My Wife

When I graduated college 4 years ago I treated myself to a solo trip of a lifetime. It was a trip to Vietnam and Thailand. It was an amazing trip. My last 8 days brought about a change in my life. I was walking the streets of Bangkok and met the most beautiful woman I have ever seen. Gorgeous and shapely like a model. She introduced herself to me as Nina. For a local she spoke very good English. We went out on a few dates. By the third date we kissed. By the fifth date she blew me. By then I was in love. Now being in Bangkok I know I should've had my guard up. I should've thought that maybe she could have a cock. But in my mind there was no way she was a he. Guess what. She was a he. But by the time I found out, I didn't give a fuck! I was in love. I was so in love that when she finally showed me her cock, I devoured it! I had never been with a guy or lady boy before. It was always strictly pussy. Sex with Nina was incredible!!! She has showed me things and made me feel things that I never had before. A year later I was back in the states and Nina has since moved here and we are still together! We have 2 adopted children and Nina is the head of the PTA. I work at my brokerage firm and she started her own business making children's clothes. Everything is perfect, right? Wrong! I caught my wife with one of the women that designs the headwear for her clothing line. What should I do? Should I kick her out? Should I ask if I can join? I'm torn. Any advice would be greatly appreciated!
