Rewarded For Being A Good Son To Them Which Was Unexpected

As I was growing up I started to fantasized about my mother, especially in my teens and puberty age. I started to masturbate myself picturing my nude mother doing me instead of dad and their swinging friends. I used to spy on them and little did I know they knew I was spying on them. I finally asked my mom why won't she give me sexual attention. She said I was underage and didn't want any trouble with the law. It was tough enough keeping her sexual swinging desires a secret from the public, maybe when I'm older and my cock matured we can fool around.
When I turned eighteen we went to the beach. My mom's tit cleavage looked so hot and her pubic hairs poked out of her bikini bottoms. We checked out the tourist trap area. Back at our motel room there was two beds. One for them and one for me. While mom was showering, dad told me I was going to be rewarded for keeping the wife swapping activity in our household a secret. I never expected sex play in this trip, just the trip it self.
Mom stepped out of bathroom with just a towel wrapped around her. Dad walked away from the bed, stood behind her, removing the towel exposing her naked body. He said, " I want to see her please please you as a thank-you for being a good son. " Mom went down on her knees , pulled my trunks down and guided my cock in her mouth giving me a blow job. Dad undressed with his cock hanging in front of us. Mom grabbed his dick yanking on it , getting it hard. Dad held mom's head into me while tugging his dick. " Our boy is a man now! " said my dad. "Let him fuck you as I watch! "
Mom spread herself on my bed with legs open and playing with her clit. Dad told me to eat her because that's what she wants. She started moaning and taking dad's cock in her mouth. I wanted to give mom the load that wanted to come out. I grabbed, squeezed her breasts as she guided my shaft in her, filling that c**t with my sperm. She showed dad the sperm that was leaking out as she held her lips open for him.
