We had an in the ground pool growing up and a friend of mine was always over swimming in it. We started horse playing on the concrete and my mother was sitting at the picnic table near the pool.
She told us to go over to the grass, and wrestle. We were both shirtless and in barefeet. My mother had on a one piece swim suit her pubic hair was very visible around her crotch.
So we moved to the grass and started to wrestle, I wore a tight square cut swim suit Marty had on gym shorts. We wrestled for maybe 5 minutes maybe more, I finally pinned Marty down in a full body pin.
My mother watched us wrestle seated at the picnic table maybe 15 feet away, she liked watching us wrestle I could see it in her face.
When I stood up I had a full throbbing erection. I walked over to the table where my mother sat and she stared at my hard cock as I stood in front of her.
Later that night when we were alone my mother congratulated me on my win wrestling.
I still get a full throbbing erection thinking about that wrestling match my mother enjoyed watching and showing her my hard cock.
