My mother's brother

I'm Miranda, 15 years old. I live with my mom. Yesterday, we went to my girlfriend's place and her boyfriend's in town. We had been planning this for a long time, so I was excited to be with my friends. Surprisingly, my mom readily agreed, because I always fight with her when I want to leave the house. There was no deadline, just to have a good time. Parks, the city, the mall, movies. But by 6:30 PM, I had already said goodbye to my friends because I was afraid my mom would scold me later, saying "where the hell have you been all this time?"

Key in the door, I open it. Loud moan, breathing. I laughed to myself, because I knew why she sent me away so easily. There's a man at our house. I tried to sneak into the living room to check on the idiot who needs my mom. I was shocked by the sight, the man was my mother's brother who was grabbing my mother's breasts with a red head while riding her.

- Ohh fuck, Anna, Anna get off me!
-What, what the, ohh shit! Miranda, how did you get here? Oh God, don't be angry! Listen to me!!
-What the fuck are you doing? Mom, what the fuck!?
-Look at me, look at me, let me explain, please!
- Well, don't explain anything, you're fucking your own brother? What the fuck, why!!??

Apart from the two of us, only William, my mother's brother, was calm and regarded the whole thing as noise. He took a bottle of mineral water from the fridge while looking at me without hiding his erect cock.

- Yes, we used to fuck, this isn't the first time.
-William, no, don't talk, not now!
- Why not? She already knows everything anyway. Listen Miranda, you can't understand this, you don't have to, but accept that we're doing this, okay?
- Do you seriously expect me to turn a blind eye to this? This is fucking sick!
- Then why is your forehead and neck sweating so much? Why didn't you shout right away? You've been watching us here for how long? Answer me!
-I just didn't know what kind of man was here....
- I believe it, but you wouldn't have spoken if we hadn't noticed. Are you a virgin, right?
- Well, I'm not a virgin.
- Then why are you staring at my dick? I need it, right?
-William!! She's my daughter!
-Anna, shut up! I know, but if she needs dick, I'll give it to her.
- Do you want to fuck Miranda?
-This is an opportunity, what do you think Miranda?

I was ashamed, but there was truth in his words.

- Yes, I would.
-No, you can't!!
- Then why the fuck not?
-Miranda, I'm telling you!!!
-No, you're not saying anything! Who knows how long you've been fucking your brother and forbidding me to do it too?!

I got naked, without shame. William watched with excited eyes while clapping.

-Beautiful, I have to say, beautiful, I didn't know you had such "gifts".
- He's only 15, you can't do this to him!
-Why, weren't you so much the first time? Miranda darling, come closer!

In front of my mother's eyes, I knelt down in front of William and started sucking his cock. Out of revenge while the pleasure drove me. My uncle's cock was getting thicker, it could barely fit in my mouth. I was in tears from the effort, it had never been this big in my mouth. I could barely breathe, as William kept pushing his huge cock up to my throat. My mother's eyes widened in shock, she didn't even know what a cock-sucking guy I was.
I pushed my panties down and spread my legs. The cock stretched me as if a spear had gone into me. William leaned over me while sucking my breasts. Mother's are bigger, but I have nothing to be ashamed of. I could handle the thrusts better and better. Oh, and for the first time in my ass, there was a cock in my ass. For a long time I thought a handsome guy would take my virginity from behind, but instead it was Uncle William. I bounced in his lap like I was some kind of toy. I screamed so loudly that I choked at the end. Warm white semen mixed with my orgasm, which was like when you're drunk. I pulled myself up onto one of the chairs, the cum still seeping out of me.
My mom held her head; her forehead and nose were red. Her eyes darted back and forth at me and down to the floor.
After a few minutes of rest, she spoke in a soft voice.

- Go take a bath and go to bed!

I obeyed, I didn't have to say anything, because I knew I had won.
The next day, my mother's brother left, probably right after he fucked me. One thing is for sure, my mother will have to share Uncle William's cock if she wants me to keep it to herself.
