Yes, she's important to you

You decide to help her that means you will comfort her today so...

"I don't wanna go to school today. Do you mind if I hang out with you ?" you tell her.

You see her face light up.

"Yes please stay with me today! I could really enjoy some company right now."

"Okay I will but at one condition. You tell mom you **** me to skip school."

"Haha, you don't even need that anymore. She likes you so much these days she'll let you do anything. You even got to have sex with her."

The surprise of hearing that makes you jump on your bed. In the middle of the action you swallowed your saliva the wrong way. You cough but it remains blocked. after a few dozens of seconds you're still not getting oxygen. Juliette first laughs then starts to understand this is not a joke then strikes your torso with her fist repeatedly to **** air into your lungs.

You're still not breathing.

So that's how you're going to die.

Your dumb ass is going to go down in history for being the first man stupid enough to drown in his own saliva.

Perhaps they'll even give you an award.

As you feel your consciousness fading you see your family at the Darwin Awards. A man lifts up a card and reads "And the winner of this year's edition of the Darwin Awards, for the award of the most random and dumb **** iiiiiiiiis..."

*GASP* air is finally filling your lungs thanks to the last strong punch from your sister. While you're still coughing and recovering from this near **** experience, she's back to laughing euphorically from the situation.

"Oh my god, that's exactly what I needed XD" she laughs so hard tears are dropping on her cheeks.

You're still taken aback by what she just said before. When you're breathing again you ask "You knew about me and mom ?"

She achieves to control her laughter even though the biggest smile is covering her face. She's enjoying seeing you embarrass yourself. "You weren't exactly quiet yesterday night." You're both sitting on the bed. Since she was punching your chest she's now resting her face on it while looking at you. "You were screaming like a beast!" She jumps her ass on the bed, grinds her big kitties on your chest, sticks out her tongue while she smiles, revulsed her eyes and screams in a lewd pornstar voice to mimic the sex you had yesterday night, as a joke," Oh yes, yes, yes. Yes mom, you're so good mom you're such a slut mom! Oh Mom I'm coming I'm coming I'm COMING!"

"STOP EW!"

She continues to tease you "Oh yes John give it to mommy. Cum for mommy. Oh my god John you're sooo gooooood."

"I TOLD YOU TO STOP!"

She stops her lewd acting and goes back to casually laugh at you. Her acting was probably a casual joke too for her but it actually excited you. You tell her "Stop being so casual about it."

"What ? You want me to say **** is a bad bad thing and that you're a bad bad boy who should stop right away ? It's cool dude. Our mom is hot. She's a freaking MILF. I'd kill to have a body like hers when I get old. I understand you'd want to fuck her."

There is an awkward pause for a moment. You're not sure what to do. Your sister is lying on your chest, telling she's ok with **** and just got you hard allegedly involuntarily. Maybe you could..

"I think you look prettier than her." You shyly say with a weak voice. Almost like you didn't want her to hear it.

She cups your face in her soft hand and says "Oh really ?" She's speaking with weak voice too, whispering at you. Your heart is running in expectation of what she's going to do. "It really means a lot to me because... I too think that you're.." Her lips are slowly coming closer to yours "...SIKE!!!!!"

She instantly got back to her nasty prankster sister character. She jumps on your lap and lies you on the bed with your back against the mattress. She immobilises you like she used to when you both fought as kids. "What you wanna do me too ? You fucked your mom and now you want fuck your sister XD ?" She started tickling aggressively you now that she's on top.

"Haha stop it!" That's your weakness. You're completely defenseless against tickles. You should have changed that in your app.

"No way I'm stopping now. I never knew I had an incestuous brother living under the same roof as me. Maybe I shouldn't let my guard down and stop wearing too tight clothes. Who knows what you're going to do to me when you can't handle yourself anymore ?"

"I swear haha I'm not going to fuck you *LAUGHTER* I don't even want to." That was a lie but hopefully she'll believe it.

She stopped tickling you. "Ok I believe you. You just wanted to comfort me I know and I'm grateful for that." She gets out of your bed. "Get out of bed. I know what we're going to do today and I need you to be ready in ten minutes."

"Okay, jeez, I'll get up already."
