I was 10 on Christmas Eve 1975.
I woke up late at night, unable to sleep, and walked towards the kitchen.
I heard noises from our family den, where our Christmas tree was located, and thought that maybe I'd catch Santa delivering presents for me and my siblings!
When I stepped into the den I saw my Mom, a slim brunette, on all fours completely naked with our next door neighbor Frank kneeling behind her banging away while he held onto her hips.
He was sweating and totally focused on her.
My Mom was 33 at the time and my Dad, a state trooper, had to work an overnight shift that night and she was totally focused on him.
I clearly heard my Mom, as she turned her head to look back at him, say "Fuck me Frank! Fuck me like that!Oh my God!!!" and she let out a series of low moans as he pounded her.
As he neared finishing Frank noticed me and smiled as I stared blankly at him.
He smiled widely and winked at me and I turned and returned to my bedroom.
I've never told anyone.
Frank never mentioned it to me growing up.
My parents are still married.
Maybe it was a one time fling between them.
I don't know and probably never will.
My Dad is 76 & my Mom is 74.
Frank is 72 now.
But every year,at summer barbecues at my parents house, my Mom insists on telling the story of how Frank saved the Christmas of 1975 by coming over and assembling bikes for me and my little brothers while my Dad worked overnight.
She always smiles and looks at him and says "Thank you Frank!" and it annoys me. Everyone smiles and some say what a great guy he was for doing that and even his wife thanks him not knowing what really happened that night.
This year she said it and after she thanked me the old bastard turned and smiled and winked at me just like he'd done that night.
It ruined Christmas for me forever.
