Mom joined Brad on the bed and gave him a blowjob. Brad let out a moan and ran his hand through mom’s short, mousy blonde hair. His other hand rubbing mom’s bushy vagina.
After a short while, mom raised her head, leaving a loud ‘pop’.
“I want your cum inside my pussy!” mom purred to Brad, tapping his chest.
I had never heard mom sound so dirty! It was almost as dirty as her cheating on dad with her own son.
Mom propped herself up onto the headboard, her arms outstretched. Brad shoved his penis inside her and sawed in and out. The strict, frigid mother who had raised me, was enjoying her own son’s penis. Her eyes rolled up and her mouth widened. She was in ecstasy!
Brad was close to climaxing.
“Ready, mom?” Brad breathed.
“Yess! Do it, sweetheart!” she screamed!
Brad came inside mom, both making loud noises which echoed throughout the room.
I ejaculated as well, a few moments after Brad.
Brad’s penis slowly left mom’s vagina, leaving a trail of white semen. He used his still-hard penis to push the semen back inside.
“Brad… Wow!” mom exclaimed.
“Just giving my girlfriend what she’s been missing for twenty-nine years,” Brad said, in a snide remark about dad.
Mom gave a, “Whew!” while wiping the sweat off her forehead.
They got into a cuddling position, mom’s leg leaning over Brad and brushing against his penis, Brad stroking her backside.
“You know, I think we’d make some gorgeous kids!” mom said with a huge smile, stroking his chiselled hairy chest.
It only occurred to me just now: could mom still get pregnant at her age?
“Course they would be, mom. They’d have a stud for a father!” Brad said.
Mom let out another purr of delight, then kissed him again.
They eventually looked over at me.
“Sam! We’d almost forgotten you were here!” she said.
“How’s that for ‘sex education’ bro?” Brad asked.
I was speechless.
They laughed together at my response and kissed for a short time longer. They whispered something I couldn’t hear, and they got up.
“We’re going to take a shower now,” mom said. “Afterwards we’ll cook up a nice meal.”
They walked out of the room, mother and son, arms around each other as lovers.
My heart was beating rapidly. I had literally just witnessed my mom and brother have incest sex in the flesh. Incest sex in mom and dad’s marital bed.
‘Dad,’ I thought. He was none the wiser.
I felt dizzy. I mean, how many guys get to experience something like this? I shakily got up and walked to my bedroom. I heard the sound of laughter from the bathroom.
It was late evening, and I heard my mom call me down for dinner. It only just occurred to me that I had been sitting upright on my bed in the dark, for over an hour. My mind was still swimming. I pulled myself together and joined my mom and brother at the dinner table.
Mom was wearing a revealing camisole, my brother wearing a vest which highlighted his muscles, as well as dad’s Rolex watch. That was dad’s anniversary gift from mom!
‘How dare he?’ I thought.
I almost called him out for it, but for whatever the reason I didn’t speak up.
