I know of several who did and wonder how common it is to continue or even increase sex with other men after a woman gets engaged until they are actually married. This can be confession time for one time while engaged too.
I have been hit on by several about to be married women. My guess it’s just like guys, a last fling.
A friend of mine, Anna, got married something over 20 years ago, just after she finished college. She had never had sex with anyone other than her fiance. About a month or so before her marriage, she began worrying that she would never have an opportunity to experience another man. She worked part time for her parents who owned a furniture store in their small city. She was attracted to one of the guys who worked there, and decided to have a quick fling with him just to see what it was like. One evening after the store was closed, she seduced him in the freight elevator at the store. She stopped the elevator on the ground floor just after the doors closed, knowing it wouldn't be used anymore that day. She then had her way with him. Anna liked it and began to have sex with him on a regular basis. In fact she was fucking him more than she was fucking her fiance. It has been several years since she told me the story, and I don't remember if she was in love with him, but I think she was. I do remember that he was in love with her and tried to talk her out of getting married. On the night before her wedding, and after the festivities were over, he came to her apartment and spent the night. They had sex that night and again the next morning, even though it was her wedding day. She had planned to not wear panties under her wedding dress. The dress had a built in bra, so that wouldn't be needed either. She was second guessing her decision to not wear panties as her new boyfriend was a heavy cummer, and she didn't want to be standing at the altar and have his jism leaking down her thighs. She decided to postpone the decision about the panties until the last minute. In Anna's community, the standard practice is for the bride to take her street clothes off in the dressing room at the church and then the maid of honor and the bridesmaids help her into her wedding dress. Just before Anna stripped naked, she went into the restroom for one last cum check. She said it wasn't dry, but it wasn't too messy either, so she decided to stick to her original plan and not wear the panties. Anna said it felt wickedly delicious to be standing at the altar, knowing she was naked under her wedding dress and that another man's cum was in her belly. When she told me this story, she giggled when she said, "I can't believe I gave my husband sloppy seconds on our wedding night." I don't know that Anna and her friend got back together again after her wedding day, but, not surprisingly, she has had other affairs over the course of her marriage. Those stories are for the telling at another time. In closing this particular story, she said, "How naive it was of me to think that my husband would be the last man I would have sex with."
I knew a girl who said she'd fucked another guy while engaged. A colleague in the back of his car. She had had several others since, one offs or longer affairs but is still happily married...
