You watched in sudden dread as Catty kicked off her sandle and began stretching you out, sort of like a balloon, causing you a bit more pain, as you watched her wiggle her toes
"A stocking human!"
You were forced down to meet, face to face, with Catty's foot. You felt the claws of her foot poke and prod at you a bit as she does so
"Um, Catty?," Bratty asked, looking down at the display in slight confusion, "How exactly are you going to get them on your foot, there?"
"Oh, uh...easy!" Catty said, it seemed she wasn't sure until just that second. That's when you felt her reach her fingers into both sides of your mouth. Oh no.
To your surprise, Catty stretched your mouth as wide as it could go, and soon, you were being pulled up over her foot, ankle and, eventually, up her entire leg, just like a proper stocking. You wanted to scream as loud as possible here, but you were completely silenced. Through your mouth, down your throat, into your stomach. Heck, you're whole body was molding an accommodating for Catty's foot. By the time she was finished, you no longer looked human as much as just a stretched out, fleshy stocking, that went up to just under Catty's knee
"OMG, it's just as cute as I thought it'd be" Catty laughed, "Super comfortable too"
While Catty was certainly enjoying herself, you definitely begged to differ. You were stretched out very painfully far. Being so stretched out. You were able to barely make out the surroundings at around Catty's leg height, but even that was difficult. You had the taste of her fur in her mouth and the feeling of her foot and her claws jabbing against your insides. You could still miraculously breath, but you were unsure if that was a net positive when you had to deal with everything else at the moment.
"Yeah, it's cute but...it's only one sock." Bratty pointed out, "I think you'd need another human to balance it out"
"Uuuuh, you're right!" Catty groaned, "Who knows if we'll be lucky enough to get our hands on another human before that dumb royal guard does!"
You were worried at the prospect of another human ending up down here and getting the fate of being Catty's other sock
"Still, for now, I wanna test this new sock out"
You thought the worst part was over, but you were soon felt Catty's legs start to move. Every part of this wasn't fun in the slightest. You were already extremely tight against Catty's furry leg, but the movement made it worse. You almost felt motion sick as she kept moving you back and forth, every step putting a lot of pressure and weight onto your body. It almost felt like she was stepping, no, stomping, right on your stomach! You didn't know how much you could take, or how much worse it could get
"Where's that stupid kid, already?!"
That voice...it was familiar. You looked through your peripheral and you managed to find Flowey. He was still clearly looking for you. He didn't seem to notice you, however. Likewise, Catty didn't seem to notice him...
"When I get my hands on you, you're not gonna see the light of day from-Aackk!"
A fact that was made very clear when she stepped on him, borderline flattening him, even with the larger rear end he acquired.
Despite being in a debatably worse situation, seeing that happen to Flowey was slightly amusing to you, but then it set in, whether or not he'd have seen you after you just collided with him thanks to Catty's foot
