Hanna was aways the top student of her classes, that didn't went so well for me being her little brother. After her amazing performance on every subject our parents had high expectations on me as well, the kind of expectations I couldn't quite deliver. That situation made us more distant, I stopped talking to her so much and we got into two different worlds.
That lasted for a while, but since last week she is acting different, way more nice to me and less stuck up. I don't know what happened to her but it's being nice do far. "Hey bro, what do we have for breakfast?" She says passing trough me and taking a look on the table, full of energy as she was lately. "It's not ready yet, take a seat." I said lending a chair for her.
"I'm going to buy some groceries, the breakfast is almost ready so keep an eye on the fire." Our mother said before leaving us alone since dad was already at work. "You hear the old hag, pay attention to the fire." She said like she was mocking mom, what was really odd coming from her. "Got it, I can do it if you wanna save some extra minutes to study for your test." I said trying to help sis since she had that important test tomorrow. "Like I care about that shit, I just told that to them so I could find a way to stay locked on my room. I have better things to do them studying." She said lowering her pants to expose her big ass, that caught me off guard leaving me speechless for a moment.
"What is wrong with you? Cover yourself sis." I said pretending I didn't liked it, she was never like that so I wondered why she was teasing me so much. "You know where to find me."~ She said leaving the kitchen and getting inside her room, after that I turned the fire off but didn't cared about eating cause my hunger disappeared, all I could think about was discovering what is going on with my sister.
I was so curious but yet so afraid of the truth, she was not like her usual self and even that being a nice things at first it turned out a bit weird right now. I knocked at the door and opened it slowly, a voice came from the inside. "I don't bite, come in bro." Her voice said sweet and inviting. I did as she said and went inside, a view I would never forget filling my eyes. I saw her wearing only panties, her ass pointed at me while I could see her fingers playing with her own pussy. With her other hand she was holding her phone watching porn, moaning softly as she enjoyed that. "You know, I had a lot of fun lately, but since yesterday I was curious about how it would feel doing it with you." Her fingers went faster, her thumb now wenting inside her asshole.
I was here to question her, but instead I was completely taken by that beautiful sight. My cock was asking to be released so it could get in there, but I felt like it was wrong and tried to fight that feeling. She stopped for a moment, like she just came. After that she let out of her phone and turned around, her breasts swaying gently as her eyes looked trough me. "Don't be so shy, it's just us in here. Let me guide you so we can have a lot of fun hun." She said getting closer, her arms wrapping around me as she gave me a kiss, I could feel her breasts pressing against my chest then he grabbed my hands and made me grab her ass. "You like that, don't you?" She whispered in my ear, the bulge on my pants rubbing against her.
"Hey kids! Have you eaten yet?" I hear a voice from the kitchen, my mom was calling us. When I turned around I feel sis pushing me out of the room. "Maybe next time, I will be waiting for you."~ Then she closed the door locking herself in there. My heart was rushing, I was looking for answers but was only left with more questions. I would think about that the whole day, and pay another visit to her room at night...
