Watching from the Closet

Hi Im Adam 19, I live with my dad Frank 48, my mom Jennifer 47, and my sister Allison 21. Our house is a older one. It seemed like it was a one room home and then a new room built on every so often. So the layout was odd, my parents room was downstairs on the opposite side of the house and the closet between my sisters room and mine is a shared closet. So one long closet that has a doorway on either end into our rooms. In theory we were supposed to share and have it 50/50, ya sure, it ended up being 75/25 hers. But it did give me easy access to spy on her over the years. I could just slip into my end and hide behind her clothes to peep.
I've seen her and many of her friends naked over the years. A few times her and a boyfriend going at it. This exploded after her 21st birthday, now I would never call her a slut. But in two months since hitting 21 she has had at least 6 different guys over having drunk sex. Great for me of course, because holy fuck it was like having a live porn show going on for my viewing pleasure. Bad because I didn't like the idea of my sister having a line that started on the left for her lovers.
One day I asked her what was up with all the different guys?
She replied, "mind your fucking business."
I shot back with "Ok then, enjoy" and I walked off. Her life really and it's not like she was using drugs, just some drinking and sex. Not like its something I wouldn't want to do sahabet güvenilirmi so, her life.
She started to dial it back some after that though. About that time my dads company got bought out and he made a nice little bit of cash as he had some stock. My folks started to take some trips and go out to parties more. One weekend they took my sister to one of the parties, all three came home pretty wreaked, mom looking worse for wear. I was in the kitchen and helped her to bed as my dad and sis sat on the couch laughing about something I didn't know what. I wished them a good night and went to my room and jumped on my X-Box.
About 2 hours later I took my headphones off for a min and I heard my sister moaning loudly in her room. I figured she must be playing with herself, I figured may as well watch the show. As I entered the closet I heard more and it sounded like she was with someone. I couldn't imagine who she had over, since I know she wasn't in the condition to go out and get someone.
When I got into my spot to watch, I looked and saw her naked on her bed with a guy's head between her legs. I figured she must have made a booty call. As I stood, watched and stroked while she was getting eaten out. Then I almost yelled "WTF" when the guy moved up to kiss her.
It was dad. HOLY SHIT! I could tell they were both still drunk. My sister said to him "oh daddy, if I knew you were that sahabet yeni giriş good I would have done this years ago."
My dad laughed and rolled to the side, he reached over and grabbed Allison by the hair while saying "if I knew you would say yes I would have, now get those lips down there" as he pushed her head toward his cock.
I watched my sister lift my dads cock and just inhale it My dad's head fell back and just kept saying "yes yes yes" over and over and my sister just bobbed her head on him. At this point i'm staring in awe, but then I start stroking again wishing it was my cock she was sucking.
After about 10 min Allison lifted her head and looked at my father while pumping his cock in her fist. "Daddy I have to have this inside me" saying as she was climbing on top of him. I held my breath as I watched his cock sink into my sister. I almost came as she did it, once he was completely inside her she just sat there looking into his eyes. After a few moments she started to ride him, she moaned "daddy, I love this cock. This is not a one time thing, i have to keep getting this."
He just growled at her "oh baby, this is daddy's pussy now, I'm going to fuck it whenever I want" As he pulled her down into a kiss.
That pushed me over the edge, I turned and came into the shirt I brought with me. I could not believe how fucking hot this was, if someone had told me I'd be watching sahabet giriş my dad and sister fuck, I would have thought they were insane.
I looked back when I heard my sister squeak, I saw my dad roll with her. He reached down and grabbed her legs pin them to her chest and tried to drive her thru the bed. Allison started to lose it, moaning so loudly she must have forgot I was even home. Shit I started to worry she would somehow wake our mother up. My dad cried out he was going to cum, Allison started to just repeat "Please" over and over. He collapsed on top of her and was just doing small thrusts into her. They started kissing hot and heavy, after a few minutes he rolled off.
After a couple minutes he sat up and looked at her "oh honey, you were incredible. I can't believe we did this" he looked worried.
"Daddy I love you, I always will. We both wanted this" She got up quickly and kissed him. "You did nothing wrong, I'm an adult I can make my own choices". I was starting to realize she wasn't quite as drunk as I thought. She continued "I wanted this to happen. And I want it to keep happening." She was just looking at our father.
Finally he sighed "honey, I want it to happen again to, we just have to be careful".
That's when my sister turned slightly and looked at the closet, "We will be daddy, no one will know what we're doing." "Now go take a shower and go to bed, we have a lot to talk about tomorrow" she said with a smile. My dad kissed her one more time then told her good night and left her room. I stood as still as a tree, hoping she would fall asleep soon so i could sneak back to my room.
When my sister said those damning words "Enjoy the show?"
