Kanata, your sister, comes to bother you at 3am while you're making mac 'n cheese. She's only dressed in an oversized teeshirt and some panties you can see peeking out from underneath the hem. Baby-blue polka-dots on white. Adorable for your little sister.

She wants some of your mac, you refuse. You made the shit, it's your shit. She leans over the counter next to you; she's trying to swat at the bowl and yoink it away while you're trying to mix in the stupid cheese powder. She's shorter than you and not particularly taller than the countertop. She's leaning over it so much her shirt's ridden up, you can see her entire cute, little ass and her kiddy panties. You could bounce a quarter off of the spring in those cheeks - best not to stare though.

She gets a hand on the bowl while you're gazing at her butt cheeks. You return the favor with a meaty handful of the back of her panties as you've done before many-a-time. You haul them up her ass, easily lifting her, like 80-pound frame off the floor by her coarse, childhood panties. You've seen this pair before. Her bare toes, unpainted, skritch the wood flooring as she dangles.

Her underwear is tearing already and she's let go of the bowl to reach back and stop you from shredding her favorite panties. It won't matter - this pair is already coming apart in your hand, a big tear drops her back to her feet as the elastic separates from worn-down cotton. Kanata's puffy angel pussy is all squished up and bulging out of the crotch seam dragged halfway up it, womanly lips spilling out from a pair of underwear meant for someone half her age.

...fuck, you needed to pound your sister one of these days. The flimsy pair of panties rips off into your palm as her entire weight snaps them, your other hand reclaiming your mac 'n cheese while she stumbles backwards. Thieving bratty hands go to her womanhood to inspect the damage while you try not to get hard at the fact she's utterly bare beneath that black shirt. Perky little angel butt and softer skin between her legs to the parts you, as her brother, had seen before but were never meant to find this hot.

"Fuck you, those were my favorite pair" she grouches, pulling up her shirt without a care in the world that you could see her naked, hairless anatomy in all its glory. She looks down, running a finger between her lilac thighs to make sure she isn't bleeding. She's not- the pair you just wedgied her with came apart way too soon for that.

"I'll get you," Kanata drops her shirt, hiding her navel and womanhood from you before slinking off back to her room, awkward gait and very clearly bare-assed with how her shirt clung to her butt as she did.

Meanwhile for you, you now had your entire bowl of 3am snack, a pair of your sister's dirty, old panties ripped clean up her ass and pussy and off, and a boner you were sorely ashamed off. You inspect the garment, coarse from a hundred washes and who knows how many years of wear. Unsurprisingly, the center that once rested over your sister's puffy pussy had a few stains. Nothing abhorrently disgusting, just to be expected with how long they'd been worn.

You felt a bad decision come to your head as she grabbed a spoon for your food and prepared to eat. You needed to trash this pair of panties before your parents got suspicious at why Kanata's underwear was ripped off and you had them, but...

You held them up to your nose, the parts stained guiding you to where her lady parts would have been. You took a deep inhale. At the same time, you clumsily shoved a spoonful of macaroni into your mouth. This was fucking stupid, but it was 3am, so you cut yourself some slack.

You had heard about how smell was 70% or something of taste and as the cheese of your mac 'n cheese melted on your tongue...

You shuddered.
