Studying is easy (single chapter story)

July 15, 2020 (Comodoro Rivadavia, Argentina)

Adelita is a 18 years old girl who has a problem: her farts.
Since she was a baby, her farts were extremely stinky, and she could clear a room soon.
She has a 12 years old brother named Francisco, which whom she often fights.
Her brother is very possessive and vendicative, he never lends her sister anything, and if her sister says something he doesn't like, he will steal something from her room. Adelita makes extremely stinky farts and when she farts, she makes all the room unbreathable. She never used this power against the brother, but now, this is too much, she will use it!
Adelita's farts are very stinky, she farts 30 times a day and they make the room smell like 5 rotten eggs every time she farts, so she often uses a deodorizer. But this time, this time he's gonna pay! And this is the right moment to do so, because...

Adelita was playing with her mobile phone, when Francisco entered her room, asking her to lend him Tekken 8. Adelita usually lends him every game, but this time she asked:

<<Can you lend me your dog peluche? I want to hug it!>>, smiling.
<<No! It's mine!>>, said Francisco.
<<And why are you asking me to lend you Tekken 8?>>, she asked.
<<Because Dr. Bosconovitch is playable, and he lays on the ground like he did in Tekken 3! It will be fun!>>, he said.
<<Just lend me your dog toy!>>, said Adelita.
<<NO! It's mine!>>, said Francisco.
<<Then Tekken 8 is mine as well!>>, said Adelita.
<<No way!>>, said Francisco, wetting her hair with bottle water.
<<Stop!>>, said Adelita, but Francisco was hitting her.
<<I have to fart!>>, said Adelita, and Franscisco ran away very quickly.

But Tekken 8 disappeared from her room.

"This time he'll get in trouble!", thought Adelita.

The next days passed, and the same things repeated, until August 3, 2020, which was the first day of school after the winter break.

<<Did you still get a 3 (it's a fail, in Argentina you have to get at least a 6)?>>, asked her mom.
<<No!>>, said Francisco.
<<But the site told me that! It's the tenth time this year! You promised you would study after the winter break! Don't use the PlayStation 4!>>, said her mom.
<<Please mom, let him use his PS4, I'll help him to study!>>, said Adelita.
<<What?>>, said Francisco.
<<Yes, I'll help you to study!>>, said Adelita.
<<Uhm... thank you...>>, said Francisco, embarassed.
<<Alright! He can use the PS4 after he studies! Check him, Adelita!>>, said her mom.
<<Don't worry mom!>>, said Adelita.

Lunch is ready, and Adelita ate beans. She had an idea to make him study well, but it's going to be revealed later, not to spoil this story. You can of course suppose what it's about.

<<With this beans, you're going to fart a lot!>>, said Francisco, to annoy her.
<<Don't worry, I know what I'm doing, I'll explain you later!>>, said Adelita.

<<Let's watch some TV! I'll study later, I promise!>>, said Francisco.

They watched the TV, there was a program about astronomy, which was the subject wherein Francisco got a 3.

<<Please, change the channel!>>, said Francisco.
<<No, we're going to watch this!>>, said Adelita.
<<Why? We'll study about it later!>>, said Francisco.
<<Yes, but you have to understand the thing wherein you got a 3! And that's basically: the seasons. You don't know what a season is!>>, said Adelita.
<<Of course I know what it is! It's summer or winter!>>, said Francisco.
<<And what causes it?>>, said Adelita.
<<I don't know. What?>>, said Francisco.
<<Earth has an axial tilt of 23 degrees, therefore we in the Southern Hemisphere experience winter from June 21 to September 23, as the Earth is tilted, we get different amounts of sunlight. June 21 is the winter solstice, where the day lenght is the least, and December 21 is the summer solstice, where the day lenght is the longest. It's not difficult!>>, said Adelita.
<<If you say so!>>, said Francisco.
<<Later we're going to study it!>>, said Adelita.

They watched the TV and chatted, it was going to be a cute evening. Adelita explained carefully the seasons, solstices and equinoxes to Francisco, but he didn't care. He didn't want to study, but he had to because otherwise he couldn't play with the PlayStation 4. Adelita knew a way to make him study, and he was going to be a very good student. Education in Argentina is one of the best in the world, but Francisco didn't want to study because he thought it was uninteresting. He didn't even know what temperature there was in Comodoro Rivadavia in winter and summer and the lenght of the day. He simply didn't care. He didn't know that Mars had seasons, too! He doesn't want to know much, he just wants to play videogames and stay with his friends. But studying is important, too! He didn't even know what Titan (the moon) was. He's never heard about that. He thinks that the only existing moon is Earth's, and that Venus is colder than Mercury because she's farther from the Sun. He didn't know anything about astronomy. He's never heard about the word "exoplanet".

<<Let's go!>>, said Adelita.
<<Alright...>>, said Francisco.
<<What causes seasons?>>, asked Adelita.
<<I... I don't know!>>, said Francisco.
<<Let's do this! I will make you use the PlayStation 4, but you should study, and we should do a thing, will you accept?>>, asked Adelita.
<<Anything>>, said Francisco.
<<Ok, sit on the pillow, so you'll be comfortable!>>, said Adelita.
<<What are you going to do with those ropes?>>, asked Francisco.

Adelita tied her brother to the front legs of the chair, and his head was on the chair.
He couldn't move his head. Adelita sat on the chair. She put her butt in her brother's nose.

<<No! No! What are you doing?>>, said Francisco, fearful.
<<I'm asking you questions, if you don't reply or reply wrong, I'll fart!>>, said Adelita.
<<Please no! You're mistreating a kid!>>, said Francisco.
<<If you don't want to use the PlayStation!>>, said Adelita.
<<I want!>>, said Francisco.

Here starts the study of terror. From now on, there will be questions to Francisco, and if he doesn't reply...

<<If you don't reply, I'll make your nose melt! Ahah!>>, said Adelita, knowing her farts were extremely stinky by normal standards.

"She's goin to kill me!", thought Francisco.

<<First question. What causes seasons?>>, asked Adelita.

Francisco didn't reply, trying to earn some time.

<<30 seconds!>>, said Adelita.

His end was near. 20 seconds left and he doesn't know the answer.

"I pray you, my God, let me enter the sacred realm of heaven, I don't want to go to hell", he thought.

10 seconds left, and he knew he was going to perish under her sister's butt.

Adelita didn't even warn, and she farted.

PFFFFFFFFFFFFFFFFFF!!!!!!!!!!!!!!!!!

A 3 second long SBD escaped Adelita's rear end. The air was so hot, Francisco thought his nose was actually melting. It smelt like 10 rotten eggs.

Francisco was convulsing under her sister's fart, it was so stinky that it smelt like brimstone hell. His body would have shaked if he wasn't tied up to the chair. He has trouble breathing, everytime he breathes he wants to cry, so he makes short breaths. He surely doesn't want to breathe that thing deeply.

<<The answer is: the axial tilt of Earth causes seasons!>>, replied Adelita.
<<I'll rephrase the question: what causes seasons on Earth?>>, asked Adelita.
<<The axial tilt of Earth!>>, replied Francisco.

It was good! Francisco didn't have to breathe her sister's fart now, it still stunk from the previous fart, but this was a good thing. Her sister provides answers everytime he's wrong, so he's going to learn very quickly.

<<Second question, what's the average high temperature in Comodoro Rivadavia in January?>>, asked Adelita.

<<20!>>, random replied Francisco.
<<Wrong! It's 25 °C!>> (25 °C is 78 °F)

PFFFFFFFFF!!!!!!!!!

Adelita released a fart that smelt like 25 rotten eggs, like the degrees of Comodoro Rivadavia in January. The fart was inhumanly stinky.

<<NOOO!!! NOOO!!! PLEASEEE!!! LET ME GOOO!!! I DON'T CARE ABOUT THE PLAYSTATION!!!>>, said Francisco.

<<Nope, you WILL study!>>, said Adelita.

Two long tears wiped Francisco's face, as he retched everytime he breathed.

<<Please, you're killing me!>>, said Francisco.
<<Reply correctly, then!>>, said Adelita, <<First question: what causes Earth's seasons?>>
<<Axial Tilt>>, replied Francisco, coughing from the smell of the previous fart.
<<What is the average high temperature in Comodoro Rivadavia in January?>>
<<25 °C>>
<<Comodoro Rivadavia gets more than 400 mm (15.7 inches) of precipitation a year, true or false?>>, asked Adelita.
<<True!>>
<<No! False!>>

PSSSSSSSSSFFFFFFFFFSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!!!!!!!

A 5 second fart was released, and it smelt like 15 rotten eggs, like the wrong inches of precipitation of Comodoro Rivadavia.

<<I give up, please let me go!>>, said Francisco.

<<No! I'll stop only when you get 5 correct answers!>>, said Adelita.

<<What causes Earth's seasons?>>.

[...]

<<Comodoro Rivadavia gets more than 2500 hours of sunshine per year, true of false?>>, asked Adelita.

<<This is true!>>, said Francisco.

<<NO! FALSE!>>, said Adelita, farting a new fart.

PFFFFFF!!!!!!

This fart was very dense, it was small but smelt like 25 rotten eggs.

Francisco was about to faint, his vision was not that great.

<<Let's do it all again! What causes Earth's seasons?>>, asked Adelita.

[...]

<<What's the coldest place on Earth?>>, asked Adelita.
<<The North Pole!>>, said Francisco.
<<NO! Vostok Station!>>, said Adelita.

Adelita made a fart that stunk like 55 rotten eggs, that is perfectly unbreathable. Francisco fainted.

He woke up 40 minutes later, with his nose still in her sister's butt.

<<What causes Earth's seasons?>>
<<Axial Tilt>>
<<What is the average high temperature in Comodoro Rivadavia in January?>>
<<25 °C>>
<<Comodoro Rivadavia gets more than 400 mm of precipitation a year, true of false?>>
<<False>>
<<Comodoro Rivadavia gets more than 2500 hours of sunshine a year, true of false?>>
<<False>>
<<What is the coldest place on Earth?>>
<<Vostok Station>>

<<YAYYY!!!>>, said Adelita, untying him.
<<You did it!>>, she said, hugging him.

The next day, he redid the test and had a 9.

<<I'm so happy for you, bro!!!>>, said Adelita.

Studying is not that difficult, but it's sure stinky.
