[MFM] My [M] now wife [F] had her first [MFM] threesome after we met. But she didn’t tell me until years later.

First time posting and fair warning the story got a little bit long.

A little back story on my now wife, Sarah [F], and I [M]. When we met she was only in town for a college internship at the company I was working for. She is about 5’5” 135 pounds with D boobs that she loves to show off. We hit it off and had instant chemistry and became an unofficial item that neither of us expected to last. We spent every night together that work or personal reasons didn’t keep one of us away from the other. This takes place on one such night that I was kept out of town, and that she didn’t tell me about until after we were married.
