Thanks to deadeye_76 for the editions. I'm submitting this story again. I hope the previous mistakes are solved.
This is one of my first stories, it involves twin siblings facing some new experiences. Both are 18 years old. It takes some build up to get to some action. But I consider it's worth the waiting and patience. Read and Enjoy.

It was a hot summer afternoon when something quite unexpected happened and it made my sister and I get closer emotionally and physically.
I woke up in my bed, my body damp in sweat because of the crazy temperature of the season. It was, according to meteorologists, one of the hottest summers registered this decade.
I put on a white T-shirt and black shorts and went downstairs for breakfast. I entered the kitchen and saw my mother preparing some pancakes and my father reading a newspaper sitting at the table.
"Good morning everyone," I said, sitting in a chair in front of my father.
"Good morning sweetheart, how did you sleep?" Mom asked me.
"Terrible! It's getting hotter every day. Can we please buy an air conditioner? I can't stand it anymore," I protested.
"We'll see honey. Let's have breakfast first."
"Hey everyone," my sister Kate said entering the kitchen. My eyes couldn't believe what I was seeing.
"What a hell is wrong with you? That's not an appropriate attire to show in front of your brother and father." Mom yelled.
Kate was wearing just a light blue bra and red panties. I couldn't believe it, but her body was pure perfection. She was skinny, quite tall almost my height, her boobs were quite big, her legs were muscular, she often does spinning at the gym, and her face is beautiful even though her hair was a mess, having recently woken up. She looked pretty no matter what style she had.
"I'm sorry mom, but it's so hot today," she said, noticing my looks on her body, but not seeming to care at all.
"That's no excuse. You can't walk around the house like that. This is not a damn strip club. This is your home. For the love of God have some respect!" Mom yelled at my sister.
My father was out of words just like me. I could almost see how he was checking her out, hiding behind his newspaper. I couldn't blame him. My sister was such a hot chick. Her skin was slightly shiny, showing the sweat produced by the heat. I have to confess; my cock was responding to my sister's body. I've never ever had a hard-on watching my own sister, but she's never wore that kind of clothes in front of me, until this morning.
"You're exaggerating mom. It's just little less clothes than I usually wear. Besides they are covering my intimates, so it's not a big deal."
Fuck, now I was thinking about what was hiding under those garments. How big were her nipples? Was she shaved? How did her pussy....stop! This is your sister. Your twin sister. You shouldn't think of her like that. YOUR SISTER! YOUR SISTER. I repeated myself inside my mind.
"Are you nuts? can't you see the point of being in just your underwear here?" Mom yelled one more time.
"Fine! I'll change, but you'll have to get the air conditioner. I can't bear another damn day in this heat," Kate told my mom in an angry tone.
"We're going right to the mall this afternoon. Now put on more clothes. No excuses this time."
Kate turned around just to show us her butt, those magnificent cheeks with her panties disappearing in her crack. She was gone, but the image of her body remained in my head, tormenting me.
"Are you happy?" Kate said at the kitchen's door. Sher returned wearing a white T-shirt, and sweatpants.
"Don't push me Kate, just sit down!" My mom said still in anger.
My sister sat on the chair by my side got her head close to my ear and whispered. "We're finally getting the air conditioner," she said with a smile on her face.
My sister and I were 18 and going to the same high school and in the same class. Even though we were living in the same house, we didn't have a great connection as brother and sister. We never shared anything, I barely knew anything about her, and she knew little about me. Anyway, we were constantly asking my parents to get air conditioning. My father thought it was a great idea. On the other hand, my mom refused to do it because it was a big cost to get the device, install it, and then pay for the power it would consume.
"Was that really necessary? I mean you in your.... underwear," I asked.
"I know it was too much. But it was the only way mom would agree to get it. I'm sorry if I made you uncomfortable."
"Don't worry. I'm also tired of this heat."
We had breakfast in silence. The atmosphere was tense. My sister's plan had some secondary effects. My mom was very angry about being blackmailed like that from her daughter. My father was immersed in his own thoughts. And I was thinking about my sister's body. I don't know how much time it would take to get over this image.
After breakfast, everyone went about their own business. I was in my room, changing my clothes, when I heard the shower going. I figured it was my sister, since my parents went to visit some relative. The thought of my sister naked showering herself in there had me all crazy. I got close to the bathroom's door and listened to some moans. The door was locked so I pressed my ear to it. I wasn't sure but it sounded like my sister was masturbating in there.
I didn't think about it twice and took my hard-on out of my shorts and boxers and started pumping it. I thought about her body I just saw a few moments ago. I was wondering when my sister became this sexy woman. We grew up together, played together, and she was this cute little girl, driving everyone crazy. And now she was a woman, a woman with needs, a woman ready to experiment new situations. A woman who was masturbating on the other side of this door.
I stroked faster, and when I heard a louder scream from her, I couldn't hold it anymore. I shot my sperm out in the hall, some of it went on the door, and some reached over two feet away from me. I had one intense ejaculation thinking about my sister. How did that happen?

By noon my parents returned home.
"Get ready kids! We're going to have lunch outside and then go to the mall for the air conditioner!" mom yelled from the living room.
I was in my room thinking how messed up was this situation. I felt guilty and ashamed. But I was also tired of this damn heat.
Soon my sister and I went downstairs to meet our parents. We all got into the car, my sister in some yellow floral dress, and me in a white T-shirt and blue shorts. I didn't want to check out my sister, but my eyes went directly on her legs and breasts. It was as if I no longer had control over my actions. We had lunch quite normally in some restaurant, and then headed to the mall.
"Excuse me, where can we get some air conditioners?" Mom asked the security guy.
"It's on the fifth-floor ma'am, you can take the elevator if you want."
"Thank you very much."
We got on the elevator which was big enough to take ten people inside. We got to the fifth floor and were headed to the stores.
"Damn it," my father suddenly cursed, "I left my wallet on the car. Can you go get it Greg?" he asked me.
"I don't know where it is dad," I said.
"I do. Let's go get it Greg!" My sister took me by the hand and we went back to the elevator.
"I could have looked for it by myself you know," I said while we entered the elevator.
"I know but we can take a reward from dad's wallet and he'll never know," my sister told me with a devilish smile.
While we were going down, the elevator suddenly stopped. The lights also shut down and it was slightly hard to see what was going on.
"What happened?" My sister said
"I don't know," I replied. "It must be a blackout or something," I looked on the screen above the door's elevator and we were on the third floor not moving at all.
There was still some sunlight letting me see around the place. We were all alone and the heat was rising every second.
"Can't you open the door?" My sister asked me.
I tried several attempts, but it was useless. The door didn't have anything to hold onto and it was tightly closed.
