Adoptive Sister

My name is Gustavo, I'm 24 years old, single and currently I live with my parents.

My mother's dream was always to have a girl, but because of uterine cancer she couldn't have children anymore.

I was 17 years old when my parents introduced me to Mia, my adopted sister, and she was only 11 at the time.

Her hair was brown, and her eyes were the color of honey, she was innocent and harmless.

Because of a scholarship at a university, I had to go to study in another city, so I only lived with her for a few months before going, and unfortunately the distance prevented me from creating an affective bond with her.

At the end of my course, I had to return to my parents' house, because I wanted to find a job in my area in the place where I always lived, what I didn't expect was to be received by a young woman made, with a sculptural body, pert ass, medium breasts, full lips and extremely beautiful and sensual.

She wore a pair of short jean shorts that showed off her thick legs, and a white blouse without a bra that left her nipples showing.

- Sorry, I think I was wrong at home, I said trying not to show how much this girl had disconcerted me.

Mia: Have you been away for so long that you've forgotten where you live? he asked mockingly.

I was speechless trying to assimilate that this was the same girl my mother had introduced me to as a foster sister just before I left for another city.

- Are you Mia? How could you have been so...I thought of the word "hot", but I would never call her that, considering she was my sister...so big?

Mia: Welcome little brother, come in. I walked in with my bags, and squinted at her ass.

- What the hell are you doing dude? I mentally scolded myself.

Mia: Our parents are working, they only come back at night, but they told me you were coming. Are you hungry?

- Oh yes of course. I had no idea what she asked me, I just nodded and stared at her curves, her back to me as she walked towards the kitchen.

I sat on the living room couch trying to catch the breath I had lost the moment I saw her.

Soon after, she came back carrying a cup of coffee and cake, and as she bent over to put everything on the coffee table, it was impossible not to look at her cleavage, where I could clearly see her pointy breasts.

Mia: Okay Gustavo, eat, I'll keep you company while you eat, he said sitting on the couch facing me. I cleared my throat a little and tried to make a conversation.

- So Mia, you don't have social media? Our parents never sent me pictures of you, nor did I find you on social media, I didn't know you had grown so much, you also never came to visit me when they came to see me.

Because?

Mia: What a lot of questions. It really was a lot of questions, but it was my way of not getting excited in front of her.

Mia: I have social media, but all of you are blocked, and our parents didn't show you pictures of me because I never let them, and I didn't visit you because I didn't want to.

Gustavo: Blocked? But why? I asked intrigued.

Mia: Because I don't like anyone looking into my life Gustavo, that's all.

- And why didn't you want our parents to show me pictures of you or wanted to visit me?

Mia: Because if you really wanted to see me, you would have come here on your vacation or holidays instead of making me go there.

- You are always like that?

Mia: Like how?

Gustavo: Inflexible and authoritarian? She gave a small smile out of the corner of her mouth.

Mia: You'll still have time to get to know me Gustavo.

- So you're not like that? Is this just a hasty analysis on my part?

Mia: You've done a good analysis, but what I'm trying to say is that you've only seen a third of what I am, in a while your list is going to get huge.

- Fuck! What is she trying to tell me with this? What a daring girl, I thought.

Mia: Finished? He said pointing to the coffee table.

Liked: Yes, I'm done, thank you. She got up and once more bent over to take the cup and plate from the table.

- Don't be a fool Gustavo, control yourself, I said mentally to myself.

Mia: Well, I'll leave these things in the kitchen and then I'll go to my room, Mom has already left your room ready, it's your house, she said turning her back on me. Mia was a complete stranger to me, not even in my wildest dreams did I imagine that little girl would turn into such a temptation.

I got up, grabbed my bags and walked to my room at the end of the hall, but when I passed one of the rooms, I noticed that the door was open, I looked and saw Mia taking off her shorts and then she took off her blouse, and her tits were the most beautiful tits I've ever seen in my entire life, and her panties were thong, and for a few seconds I found myself pushing her panties away and getting into that attractive little ass.

- What the hell!! I need to get out of here, I muttered under my breath, walking as quickly as possible to my room. The clothes were choking me, I urgently needed air, and my dick was so hard, it was hurting from the tight pants. I unbuttoned my pants, pulled my dick out and started jerking off, thinking about Mia's ass, and it wasn't long before I spilled all my cum, smearing my clothes. - That can't happen, she's my sister! How clueless I am! I said trying to balance my breathing.

I had barely arrived, and I was already sensing that I was in big trouble.
