Teacher Wife on the DL

So for the last two years, I’ve been having an after school affair with one of the coaches. My husband complains because I’m always home late from work but if you only knew what I was doing at work. I want to tell him but I also don’t wanna stop with the coach because it feels so good to have another man take me that way. So I guess I will just keep being the good wife at home and the dirty teacher for the basketball coach on my desk. Does anyone have any suggestions or comments on the way that I should handle this DM’s are always open
