I apologized for cock flash to mother in law MIL.
So I have flashed the the MIL several times now. She clearly knows it was not an accident but she talks to me normally. When I apologized I said I was sorry if I wasn't "covered up" when I came into her room a couple of weeks ago. (The act of apologizing was a big turn on btw). She said I was being silly and there was no need to apologize. Anyway following this conversation I won't be wondering into her room again with my cock and balls dangling out of my underwear (well I don't think I will).
Having said that I do intend to make the most of the any opportunities if she leaves her bedroom door open. Surely this is fair game? If she lies in bed looking out of bedroom door when the bathroom is across from her room (aka the spare room) then she might expect to see more than expected?
