Crawl to safety

I looked up and realised that the Devon was walking towards the window. I panicked but knew I couldn't make any noise and I had to stay out of vision. Still trembling with the after shock of my sissygasm. I mustered all the strength I had left and aimed to crawl and get underneath the window it was my best shot.

I heard some whispers but nothing else I'm sure they didn't catch me.

"Well maybe your son woke up and knocked something in his room?"

"Yes maybe, I'll check on him soon but I need to finish you off don't I."

I then decided to risk it I wanted to catch one last look at my mum's lover who had given her and myself a great night, I peeped so it was just my head looking over whilst I was still lying down. Devon stood above my mum who was on her knees in front of him, he was still hard and the well used rubber was all stretched out and hanging down from his cock was again a large tip full of the cum. Mum pulled the rubber off with one hand and flung it into the bin.

"You can clean my cock off properly now." He said moving towards my mothers head.

"Yes master" Mum moaned.

That's when I first really saw this black guys cock. It was uncut and huge. Large veins ran down the shaft. The head of the thing was just peeking out of the cum covered foreskin and was so black it looked purple. It looked a lot bigger now that it was not covered by that rubber. The head of his cock was massive, a large drop of cum hung at the end of his tip. He pushed his cum covered cock up to my moms lips. She looked at it for a second and then quickly sucked the dick into her mouth. Big veins, foreskin and all disappeared into her lips. I lay there watching as she worked over this large black cock on her knees. He pulled his clean cock from her mouth with a pop.

"Dam, look at the time, I better get home from work, my wife will have dinner ready now." He said grabbing his clothes up and pulling up his shorts and getting into his pants.

"We wouldn't want your wife to know you've been deep in a white women for the last few months, now do we?." Mom said with a grin.

He smiled back as he opened the door to leave.

"Hell no, and don't worry, I'll be quite so that your boy will never know that anyone had been here at all."

They kissed again, as my mum stayed on her knees, when he left my mum simply got up and rolled onto her bed. She laid there with her legs open and I could see that her cunt was stretched wide open.

"See you at work tomorrow babe." He said as he left.

A part of me wished they could be together they clearly have something based on that interactions and incredible sex I just watched.

I went to sleep thinking that he wouldn't be a bad step-father.
