We ate dinner and went to the bedroom. I followed them to their room. Dad didn't say anything as he knew that his son was sick.
After entering, Mom told me to lie on the bed. So I nodded and joined Dad.
Mom removed her dress and was standing naked in front of Dad and me. Dad looked at Mom, then me and then looked at Mom again.
"It's your first time being like that in front of him."
"Yeah." She then looked at me and said to Dad teasingly "Look, how your son is ogling your wife's body in front of you."
Dad looked at me and laughed and said "His mind may return to being a child but his hormones didn't."
"Mummy, I want milk."
"Wait beta."
She came and lay down between Dadda and me. Mom pulled me closer and gave me her nipple to suck. I sucked for a while but I didn't sleep.
"Honey I am horny." Mom said to Dad with lust in her eyes.
"But, he is not sleeping."
"Yeah, I know. But I am really horny. Just touch my pussy and you will know."
Dad touched Mom's pussy and saw that it was completely wet.
"We have already done this many times in front of him when he was a child. You even fuck me a few times in front of him two days ago."
"Yeah, ok, let's do it. We have done it many times in front of him when he was a child. Now it's the same."
Dad excitedly got up and moved towards her pussy and touched it. He was also getting hornier seeing his wife's wet pussy.
Suddenly another hand touched it. Dad paused and looked at the owner of the hand. He saw his son still sucking his wife's breast but was also staring at him.
Mom grabbed my hand and moved it and said "You go ahead. He must be trying to copy you." Though she moved it, the hand was still in her abdomen.
Dad laughed and went between Mom's legs. He set his dick and pushed hard.
"Aaahh!"
"What are you doing, Dad? Stop, Mom is hurting."
I was about to get up when Mom pulled me and hugged me tighter. Dad didn't care and he was ready. He knew this might happen. So instead of stopping he increased the speed.
"Aaahh! Ummm! Uhhh!!! Aaahhhh!"
"Stop it." I tried to act like I was about to cry.
Mom lifted my head and said "Your dad is not hurting me, son. He is fucking me."
Dad looked at Mom astonishingly and started to move even harder.
Mom looked at Dad's excitement and said "Yes, your dad is making your mom crazy with his dick. Oh honey, fuck me harder."
"But. You look like you are in pain."
"I am not honey. Mom showed her happiness like this." She then looked at her husband and said "Honey, show our son how happy you can make your wife."
"OK, dear."
Mom then said "Look, Mom is not in pain."
I then stared at the place where they were connected without blinking. Dad got even more excited and started to pound Mom with all his power.
Dad looked at his son as if he were showing off his skill to him. Just then he noticed a bulge in his pants.
Dad was surprised. He looked at Mom and made some eye gestures. Mom also looked at the bulge in my pants. She acted shy but also gave her dad a crazy horny look.
Dad smirked and started to fuck mom harder. Mom's moaning was getting louder.
After 15 minutes dad cummed inside mom and fell on her. But I of course pushed him away acting as if I was angry at him.
Dad shook his head and Mom tried to help Dad by consoling me. Dad was tired so he slept after a few minutes.
After he slept, Mom kissed me and whispered in my ear "I felt very hot when you were looking at us."
I hugged Mom and Mom secretly took out my dick and started to masturbate me. She smiled and looked at Dad from time to time. She didn't make any hard movements.
Just when I was about to cum mom put my dick in her pussy and told me to cum there. So I cummed inside which was already full of dad's cum.
