As soon as the man was done ejaculating, he climbed off my mother, freeing her cum-splattered body for whoever wanted to fuck her next. With mom’s eyes glued shut and her legs spread wide, I realized I was facing a once-in-a-lifetime opportunity to fulfill my darkest fantasy. If I whipped out my cock now, I could slip it into my mother and fuck her while she was blinded. I knew I wouldn’t need long, as I was about to blow my load just thinking of her. I could fuck mom, cum on her and she would never know. I could even cum inside her if I wanted. I might have done it too, if it hadn’t been for one thing.

One glance at my sister was enough to make up my mind. Even though this could be the only opportunity I’d ever get to fuck my mother, I would never even attempt to have sex with another woman without Michelle’s explicit approval.

Before I had a chance to change my mind, another guy got between my mother’s legs and fed his cock into her. Oblivious to my moral hang-ups, mom was being pounded again and was moaning with every thrust of the guy’s cock, racing towards her umpteenth orgasm.

“I love you so much right now” I heard a soft voice in my ear. Looking up, I saw Michelle, smiling proudly. Of course, it wasn’t much of a surprise it was her. What did surprise me was that she appeared to know exactly what was going on in my mind.

“Remember that thing you’ve been asking for?” she whispered.

I nodded.

“Tonight it’s yours” she said and then she turned around again.

I almost came in my pants. I was going to fuck my sister’s ass tonight!

Michelle smiled naughtily at me and gave a wink, wiggling her ass as we both got back to work. Mom was literally dripping with cum. Her face, stomach and breasts were scattered with dozens of slimy streaks. My sister scooped most of it up with her fingers and fed it to mom, then wiped the rest off with a damp cloth to create a blank canvas for the men to unload on.

It was well over four hours later when the last guy announced he was going to cum, pulled his cock out of mom’s pussy and shot his load over her belly. Most guys had cum two or more times and were too tired to go again. The few that still managed to maintain an erection gathered around her and started jacking off. In one sloppy finale, nine guys fired their cum at mom’s face.

Mom was completely drenched, her whole face was glazed and her matted dark hair was stuck to her skin.

“Thank you guys” she said, looking around with blind eyes, “That was awesome”

The guys cheered and with that, the gangbang was over. We all drank a glass of champagne and then the men retreated to the garage to get dressed. Fifteen minutes later then they left, one by one, until it was just mom, Michelle and me.

Mom was tired and sore, but happy and thoroughly satisfied.

“I love you so much” she said, her voice hoarse from all the screaming.

“We love you too mom” Michelle said, embracing her.

Mom beckoned me and although she absolutely reeked of sperm, I joined them in a group hug.

“God. I’m starved” mom said after she released us.

“Me too. At least you’ve had some protein today” Michelle quipped.

“Hey! I’ve been working my ass off here!” Mom laughed and refilled the glasses.

“What shall we order. Chinese?” I asked.

“No, mom’s already had Chinese today. Three of them, I think” Michelle joked.
