Strip-tease for Uncle

It was Friday night and I was on my phone with Bruna, my stepfather's niece:
- Mila! Can I come over tomorrow so you can help me blog?
— Yes, you can! “I answered” — But it comes after three that I will work in the shop until two!
And after two more minutes of talking, it was agreed that she would come the next day.
Bruna and I are not friends, we're not the kind of people who call each other or hang out, our conversations happen only when there's a family reunion. At the last meeting here at home, she asked me for some information on how to blog, and during this week, she called me twice, and I thought it was weird that her sudden interest in computer science didn't match her profile.
The next day I woke up badly, I felt a bad cramp, I went to work at my mother's store and tried as hard as I could, because Saturday there was a lot of movement, but soon my mother realized that I was in the way more than helping, she dismissed me when it was almost 11:00, gave me money for the taxi and sent me home. There was still time for me to get better, otherwise I would call Bruna and ask her to come another day.
When I got home, I was surprised not to hear the sound on playing those cheesy songs that my stepfather loves, I thought he'd left, but when he realized a women's jacket that wasn't mine or my mother's, thrown over the couch in the living room, he lit my warning signal. I went to the ends of my feet not to be noticed, silent as a cat I went up the stairs and heard a female voice coming from my mother's room, when I came close to the door, I recognized Bruna's voice, from the little I heard of the conversation, it was clear that some dirty thing was going there. I decided not to interrupt that bitch. I was gonna watch more. I walked out the next room, jumped to the balcony, with one eye on the window corner I watched through the grate.
Bruna had just taken off her skirt by just wearing bras and panties, seemed to make a strip-tease or an amateur erotic scene, she loosened her bra and making charm, smiled while holding him still covering her breasts.
I still had no vision of André (my stepfather), because I didn't want to risk being exposed too much and being seen, but I could hear him.
I saw flash lights and I didn't believe that he was photographing her naked, she didn't even care and kept showing off, took a few dance steps, loosened her bra on the floor, squeezed her breasts massaged and then offered them provocatively, went down her hands smoothing her body and twirling down her panties maliciously to her feet. The flashes continued. I thought, “How stupid they are, they are producing proof of their dirty things.”
After she took her panties off, she smiled pretty dirty offering it to him and threw it towards the bed. What a bitch! How come I didn't realize before there was a climate between them?
The bitch looked more like a big girl, like the skeletal models of the catwalk, but I confess I thought it was cool that skinny white body, contrasted with her dark, long hair. Your breasts are kids, your little butt, but round, long, thin legs that leave a space between your thighs displaying the slant of your racy-hair pussy.
She went towards the bed and left my point of view.
I snuck over to the other side of the window to be able to watch them in bed, and I sat there and watched and put my iPod on.
Bruna was on her knees next to the bed, caressing the penis of my bastard stepfather who was already naked sitting on the bed, that FDP, should be finding himself the badass, fucking mother, daughter and her niece in the spare time. I refocused on that moment, left revenge for later.
The little bitch clinging to the limb lowered her head and walked with her tongue down to the top and returned walking with her tongue on that limb to cuff him then swallowing and sucking. Even if I didn't participate, I could feel how good that penis was. My stepfather kept pouting the head of the bitch who sucked him all over. Besides being jealous, I was very horny, despite the anger that consumed me for playing the innocent and letting them use me so that she could infiltrate here at home while my mother and I were away. Now I understand her interest in computer science.
The guy was still sucking when he grabbed her by the arms and laid her down with his back on the bed and went over her kissing her, rubbing herself and almost crushing that fragile body. André went down with his mouth and stopped for longer in his small breasts, the bitch with her eyes closed, corresponded and gave herself up showing they were already very close. I practically felt that wild tongue in my pussies, I took my hand to my pussy, it wasn't hard for me to start touching my pussy through the spans of my slack shorts and over my panties, which was already wet.
The sadist now subjected her to his whims of male, he caught her brutally and turned her face on four, slapped her on the ass and put her mouth and fingers on her pussy and ass, the little bitch groaned and squirmed all over like a reptile, snatched her ass and supported her face on the pillow. I shuddered in desire, I knew it was the moment when he would penetrate her with his limb and even relaxed spreading my legs imagining that I was the one privileged... Kneeled down behind her, and began to insert her penis into the pussy that should be dripping so wet, he was not anything tender, took a rough shot pulling out cries of pain from her prey, shorty also moaned together, knew that she just as I should be loving to feel that limb extending her sex, she groaned like a wounded bitch with her face stuck in her pillow.
And the weather warmed up on the porch, when I noticed it, I had my two fingers stuck in my pussy, I couldn't hold it anymore and I let go of a yummy moan that I covered my mouth with my hand.
He didn't take long to get it out of her, who was still on four and submissive... What a slut, she snatched her ass more by offering him ass that without wasting time she had fun with her tongue in that ass and at the same time lubricate it. Then he fixed his penis and pushed into the ass of the skinny woman crying and moaned a lot, sure as a pleasure, because she was shaking her ass like funk dogs. Ahaa how I wanted to feel that pain and that whole limb inside me... I smothered one more moaning and shuddered at my orgasm that wet all my hand and my panties that was just far to the side. I'd float around with my eyes closed, come and hear the girl's screams and groans. When I heard André's cries, I realized he also reached the climax...
After he was satisfied, he pulled it out of her, saw that open hole puking sperm, he cleaned her with his shirt not to wet the sheet, she got up and ran to the bathroom that stands there in the room.
I'm still jealous. I walked away from the balcony carefully before I was seen. I was very angry and, facing them both at that moment was not prudent, her sudden interest in blogs and computer was just a pretext for my home without raising suspicion. I think they've been having sex a lot longer, maybe at her parents' house, because André always goes there.
But I still make a profit. The video I made one day will be useful.
Shortly after I called the phone of the pyrigette, and although it was already much better after some orgasms (laughs), I said I was feeling a lot of cramps, took medication and was going home early to rest. I asked her to come the other day, the bitch pretending she wasn't in my house, and working all her falsehood said,
— I hope you'll be okay soon! - I'll go another day then!
I went to the house of a roommate who lives nearby. I'd give Bruna a break. When I went home, an hour later, neither one of them was there. It was better this way, because I don't know what my reaction would be, or I would slap André or spread my legs at him – I was still climbing the walls (haha) – But this one's gonna have change. Let them wait for me.
Kisses, friends, till next time!
