The open family

I left my locker key at home again. Luckily, I noticed it just in time and was able to turn back to get it. I opened the apartment door. My room opens from the hallway, so I quickly got the key out and was already putting it in my bag when I noticed strange noises. It was as if I heard a woman's scream from my brother, Peter's room. When I opened it, a sight I didn't expect immediately appeared before me. My brother was fucking my mother in the ass, and she was obscenely encouraging her son:
- FUCK ME BABY! Fuck your mother's insatiable pussy all over the place with that divine cock of yours. AAA!!!

I almost felt nauseous as I saw them moaning, groaning and screaming while they were having a wild time.
-What the fuck are you doing, Jesus!!!! Mom!!!
My brother raised his head in alarm.
- Laura, please let me explain... I... what...
-Peter my little boy, don't worry about it, just pay attention to me!
-Mom, what the fuck are you doing??!- I asked them again.

My mom turned away from my brother's cock and looked at me bored. She was a beautiful woman, I inherited my eyes from her and they said I would have the same build. She was my role model and the model mother in the neighborhood who lives for her children... and now she's riding her son's cock.
Mom really turned towards me, but only so she could look me in the eye when she lowered her asshole onto my brother's cock again. She was riding the cock up and down as if nothing had happened.
-So you, did you forget something at home?
-Oh my God, mom, do you realize what you're doing? You're fucking my brother, your own son!
-And, this isn't the first time we've done this.
-You are sick, fucking sick, I am disgusted by you!
-Calm down Laura, these are natural things, your brother and I just love each other a little more.... Ohhmm...Yes Peter...-she said to my brother as if I were not even there.
-But... but... this is incest!
I don't care, the only important thing is to have a dick in my pussy, and your brother is a perfect lover, unfortunately your father doesn't care about me anymore, it's always work, friends. Here is a young dick and you want more and more of it. You need a dick inside you too!
-But I'm only 14.
-That's more than enough, that's when I started my sexual life too.
-You said earlier that dad was the only man in your life.
My mother laughed out loud.
-Laura my dear, by the time I met your father I had countless dicks inside me. Now this dick that's going inside me has awakened old desires that I've buried. Don't you want to pleasure yourself?
She jumped off my brother before I backed out of the room and grabbed my arm. She caressed me with her hands and breathed on my face. My little skirt, my T-shirt and my bra that held my apple-shaped breasts fell to the floor.
-Mom, I don't....
-But yes, I know that's what you want and we can give it to you, help you fulfill yourself and become a woman.
It was sick. I was disgusted by them and myself, but I couldn't control this inexplicable good feeling in my body, my brain started to shut down and pleasure started to take over in my head. The desire was overwhelming and overrode everything in me. I threw away all my principles and only cared about the tingling sensation of kisses going down my neck.
My brother watched with his big brown eyes and his erect, foamy cock.
-You're so hot Laura.
-Of course she is, she's my daughter. And I hope you're just as much of a slut as I am! Go, it's time to deal with your brother!
I timidly lay down on the bed, spreading my little pussy apart. Since my vibrator had already broken my hymen, the cock penetrated me without hindrance.
-Ahww, so this is what it feels like! How does it feel to be inside me?
-You're fantastically tight Laura, ohh!
Mom grabbed Peter's shoulder.
-Time to show your sister your manhood. Come on son, fuck your sister, fuck the little whore!
I quickly pressed my breasts against his muscular upper body, rubbed them wildly and started moving on him. When we finished making out, a thin layer of saliva still dripped from my mouth. I winced as I felt the increasingly intense waves in my vagina. I felt almost free as I moved more slowly on my brother's cock. I was so grateful to him that I ignored the pain in my pussy and the weakness in my arms and legs.

Mom took some lube from the drawer and smeared it on my asshole so that the rear penetration wouldn't hurt so much. Finally, when she thought I was ready, she turned me so that I could cum inside her and put pillows under my knees so that my bottom would push it up even higher. Looking back, I saw Peter smiling and walking towards me. He must have been so aroused by the sight of my pink, wrinkled little asshole. He stood over me and thrust his cock into me with a beastly growl.
At first it hurt, but then the pain went away and was replaced by an unusual, pleasant feeling of a warm rod sliding in and out of my anus. After a few minutes I was already stimulating my clitoris and pulsing under my brother.
- Ah Peter, this is sooooo good. I love the way you fuck my ass, push it all the way into my stomach, don't be stingy!
- Ohh Laura, I'm coming, I'm coming right now!
I immediately knelt before him and waited for the blessing.
-Enjoy me, cover my face!
As his body tensed, his penis began to twitch in my hand and he covered my face with his hot, thick cum. He shot a good dose. I closed my eyes to keep the white, strange-smelling liquid from getting inside, but I felt it covering almost my entire face. I happily wiped it with my hand and collected it in my mouth. It tasted salty and I found it very delicious, so I decided to suck my brother off and swallow his cum whenever I could.
-This is the face mask! I am so proud of you.
- Sorry mom for getting so upset, this is really great and I always want to do it too!
- It's okay, honey... but draw a number, because this dick is mine in the first row.
-I can handle both of you.

-Oh my god, I'm late for my first class! Peter, don't you have school today? Well, wait, you're supposed to be sick. I understand why you stayed home.
-Have fun, sister, I'll fuck Mom a few more times while you're bored at school.

-Shall we do it today?-I asked, taking off my shoes at the door.
-Not today, for sure, but tomorrow we can continue our little incestuous adventure. Hi, darling, have a nice day!

This is how I became a part of my mother and brother's sex life, which was one of the greatest gifts of my life.
