The most incredible night of my life happened just last week. I awoke to noises coming from the hallway. It sounded as if someone was in pain. So I jumped out of bed and slowly opened my door an crept down the hallway. The sound sounded as if it was coming from my parents bedroom. "That seemed strange?" I began to ask myself. The noise was getting louder and it differentiated from what I heard through the muffled sounds from my bedroom. The noise I was hearing now sounded more of pleasure than pain.
I never once, even slightly remembered a time when my parents were having sex. For all I knew there sex life was kinda stale. But from the sounds emitting from their bedroom it appeared that it was defiantly not stale.
I put my ear close to the door to listen in closely.
My dad with a hoarse voice I heard say to my mother, "Suck my big cock, oh god yes, suck all my cum out of it"
I couldn't believe it. Through all my years I never once heard my dad cuss or even my mom for that matter.
"Fuck me now you big boy." My mom said, "Stick your big cock in me and fuck me silly."
I couldn't think at that moment. Here I was outside my parents bedroom listening to them have sex and I was getting a hard on. Was I sick for this. I don't really know. All I know is that I was really turned on and wanted to find out more.
So I slowly took hold of the door handle and slightly opened the door. I looked in and again it all hit me like a ton of bricks. There was my mom on her back spread eagle and my dad like a jackhammer between her legs. My dad was giving it to her hard and fast. My mom looked to be in another world by the look on her face.
"I'm going to cum again," I heard my mom say. "Give it to me hard and make me cum again and again," she said in between gasp.
My mom moans and moans loud as a huge orgasm hits her. "Oh my god, fuck me baby, yes, oh yes," my mom said in total ecstasy.
My hard on by now was hurting me. I couldn't believe how turned on I was by watching my parents have sex. I just had to have some relief.
So I pulled my cock out and started stroking it to my parents having sex. I was getting into and about to cum when something happened.
My sister walks out of her room which is right across our parents and lets out a gasp. I hear and while still stroking turn to see what the noise was and I start shooting my cum all over my very own older sister. It goes all over the front of her long t-shirt. But to my surprise she didn't say nothing just looked at me with a devilish grin and took her finger scooped up some of my cum and sucked it off her finger, before walking to the bathroom.
I just stood there stunned. I couldn't say a word. Was my sis mad at me. Surely not by her actions. "Why?" I asked to myself, "Why did Mary do what she did?"
Maybe I'll never know but I am tempted to find out sometime. So with that I put my cock back in my underwear and strolled on back to my room where I laid in my bed and thought bout everything that just happened.
I laid there for around maybe a half hour before I hear a knock on my door. I ask "Who is it?"
"It's your big sis, now open up or I'm just gonna walk in now."
"Ok, ok; come in," I said nervously.
Mary opens the door in just her bra and panties. I couldn't believe how sexy she looked with her nice shapely ass and nice small but firm breast. So with a grin and a twinkle in her big brown eyes, that were slightly covered by her wavy blond hair. She slowly struts ever so sexy and sits on the edge of my bed.
"I'm sorry," I began to say before Mary cuts me off; "It's ok, I know I was surely turned on by listening to my mom and dad go at ."
