I had just got home from my date with Brad, the house was dark but not silent. Mom and Dave were in bed and I could hear Mom moaning, they were fucking again. It's not unusual to hear Mom, I often lie in bed masturbating as I listen to her.
What I often wondered was if Mom was faking or if she was really having an orgasm.
As I headed to my room I noticed their bedroom door wasn't closed properly. I stopped at the door pushing it open a fraction further, curiosity had the better of me, I wanted to see if she was really having an orgasm.
There was just enough light coming in through the bedroom window to allow me to see what was going on.
Dave was my step father, he married my Mom about 4 years ago. Dad had run off with his secretary 4 years earlier, it took time and a lot of encouragement to get Mom dating again. After several unsuccessful dates she meet Dave, he's 5 years younger than Mom but they hit it of straight away. They dated for 6 months, got engaged and were married all within a year of first meeting and have been madly fucking each other ever since.
To be honest I do feel like a third wheel at times but Mom wants me to stay.
She knows that I would struggle to afford the rent and other expenses if I moved out and our relationship got even closer after Dad ran off. More like sisters than mother, daughter and at times I was the only thing that kept her going.
She was more than happy if I lived at home forever.
Dave was lying on the bed, Mom straddled him, her body moving up and down on his cock. Her head was leant back looking towards the ceiling, her long hair hanging down her back. Dave's arms were stretched out, his hands holding Moms tits as they bounced with her movement.
Mom was moaning loudly as she bounced on his cock, "Fuck I'm going to come," I heard her say as she she let out a even louder moan.
"Let me taste you," Dave said.
Mom lifted herself off Dave's cock, she moved her body placing a knee either side of Dave's head.
I was staring at Dave's cock, it was impressive sight, sticking up, big and hard. It looked bigger than Brad's.
My attention was drawn away from Dave's cock by Mom moaning again.
She was grinding herself against Dave's face, her arms outstretched, pressing against the wall.
Dave had one hand pinching her nipple, the other was squeezing her ass.
"I comin Baby, Momma's going to come all over your face," Mom said.
I was a little shocked to her Mom refer to Dave as Baby and herself as Momma. But she wasn't the only one about to come, my hand has been between my legs since I first peeked in and I could feel my own orgasm building.
A shriek from Mom and her body shaking signalled an orgasm surely she's not faking while she's riding his face.
Mom climbed off Dave's face, she laid beside him, kissing him.
Dave rolled her over onto her stomach then pulled her ass upwards until she was on her knees, her head resting on the mattress.
He was behind her rubbing her pussy with one hand, stroking his cock with the other.
His cock looked impressive, so big and hard as he stroked it, I wished it was me that was about to receive it.
"Fuck me Baby, feed Momma your big cock," Mom said.
Dave moved in tightly behind Mom, she moaned as Dave pushed his cock inside her.
I was biting my lip, my pussy dribbling as I watched Dave fuck Mom. I'm not as loud as Mom but I knew I was about to come and I wouldn't be silent.
I rushed to my room and laid down on my bed. I frenziedly fingered myself, my eyes closed, listening to Mom moans as Dave's cock pounded her pussy, imagining it was my pussy he was fucking.
I moaned myself, my body shaking with an orgasm just as I heard Mom shout, "Fuck Yes."
I laid in bed panting, normally Mom isn't that loud, maybe her and Dave are a bit wilder when I'm out.
"God I wish Brad could give me an orgasm like that," I thought.
Next morning there was a knock on my door and Mom came in.
"Morning Sweetheart, brought you a coffee," Mom said.
"Thanks Mom," I said.
"Did you have a good time last night, Brad is such a nice boy?" Mom asked.
"It was alright, I guess," I said.
