Mom made me a Dom

My parents were married for almost 20 years before i came along. This meant they had nephews that were anywhere from 17 to 19 years old.
My father worked out of town during the week and my cousins would come to visit, often.
I remember when i was around 4 or 5 years old, playing in the living room, sitting on the floor watching tv. As usual, one of her nephews (my cousin) was there.
I heard a loud thud and turned to see he had my mother pressed, face first against the wall, she was looking at me, i was terrified. I heard her say "not now, he's still awake". I remember he pulled her blouse up, exposing mom's huge tits, ( she had a beautiful set of tits). I noticed he was squeezing one of them very hard while still holding her firmly on the wall.
I looked at my mom for some kind of "what do we do?" because i was frightened, i expected to see fear in her eyes. But what i saw, i did not know the look on her face until i was much older. It wasn't fear i was seeing in her eyes, it was lust. My mother was a sub.
Mom was turned on by being manhandled and controlled.
When i finally got older and was figuring life things out, i realized that i wanted that power, to be able to make a woman wet between her legs just by being aggressive. I never witnessed any more encounters of her doing such naughty things, but just knew that her nephews came to vist, alot when Dad was away.
