Did Your Mom Tease You?

I think many Mom's knowingly and unknowingly tease their sons, maybe just to educate them on what a female body looks like, or knowing that their sons are curious give them a bit of a show. I'm sure my Mom knew that I was trying to get some peeks and once she was in the bath with the door slightly ajar, she slumped down in the bath so her pelvis moved out of the water exposing her bush, she stayed there for some time, slapping the face towel on her pussy and pulling it towards her. It was so exciting for me to watch - I don't know how she didn't hear me, or know that I was there. or did she?

Please respond with your story, I think it's quite common.
