I slept with my friends husband
My friend (who was a teacher of mine) and her husband have an open relationship. She doesn't seem to be as comfortable with it as he is. When she's out of town we regularly sleep in the same bed and occasionally have s**. Regardless of whether or not I have a boyfriend. She has no idea, neither does anyone else. I pretend not to tell her because it might hurt her, really I just like the arrangement we have.
I didn't know they had an open marriage the first time we had s**.
