Time for Simone's stretching exercises.

"Guess what Sis, Mom finally agreed with me that your backpack's technically clothes and there's no way you should be allowed to wear or own even that!"

"W-what? But i need that for my school supplies! Why'd she change her mind?"

"She only let you wear that since you convinced her you needed it for your studies. But today i told Mom about an epiphany i had, girls really don't need any kind of bag or purse since we all technically have THREE built in."

"Wha?"

"Your pussy, Simone. From now on you're gonna have to carry everything in your pussy!"

"WHAT?! NO! How am i supposed to fit all my stuff in there!?"

"Well Sis, i can already tell from here you're way looser than a virgin should be. What, do you fist yourself nightly? Regardless, I already humbly volunteered to help stretch, wreck and loosen your holes until you can snugly fit even a whole person inside!" She said before forcing her entire fist deep into Simone's birth canal.

"KYAAAAAAHH!" Simone orgasmically screeched.

"Wow! That went right in, no lube or anything. This'll be a piece a cake. Hey is that your cervix? Let's go all the way!" Simone felt the sting of her sister's fingers pushing into the hole of her uterus. With another quick thrust, Simone's sister tore open her cervix and fit her whole hand inside her womb.

"NYOOOOOOOH!" Simone cried in painful pleasure, squirting wildly all the while.

"Hooh, nyuh... Nyooou shaid dat girls had three bagsh built in... Whad are my udder two...?" Simone whimpered.

"Well besides your womb, the other's obviously your colon!" She punctuated by fisting Simone's tender and gaping asshole, forcing her entire forearm inside down to the elbow.

"HIIIIIIIIIIIIIIIIIIIIIIIIIIH! And the third?!"

"That would be your bladder... That's right Simmy, your pee-hole's your new pocket. And i'm gonna stretch it so wide that you'll never be able to hold in a drop of piss for the rest of your life! ....Ah. My hands are a little too preoccupied to fist your pee-hole. Ooh! I got an even better idea! Hey Simmy! Wanna see what your womb and colon look like when fully prolapsed? I bet i could even make your uterus go completely inside-out! Let's see what your ovaries look like!" Full of morbid curiosity, her sister grabbed on tight to Simone's insides, even hooking her fingers in the holes of her fallopian tubes before pulling back hard, trying to tear everything out of Simone's body.

"SHTOOOOOP!!!!" Simone howled.
