Chapter Text
Abby is at home, playing computer games when she hears her sister come back. She and Zoe are both in their late teens, medium height and curvy with dark hair and pale skin. Despite nearly identical looks, they differ in temperament. Abby is the quiet, geekish one of the two, whereas Zoe is more interested in sports and boys.
"Hey sis, how was your date?"
"Oh marvelous. He even let me eat him." Zoe pats her lumpy exposed belly for emphasis. It is lumpy person sized, still wriggling frantically even though the rounding out of its shape suggests its occupant has already softened, slowly but surely on his way to becoming a formless blob of thick, rick nutrient goo.
"Mmm, you look so tasty like this, sis. Can I eat you?"
"Sure." Zoe strips off her top, exposing pale, round, firm breasts.
Abby leans down to them, licking one of the sizable mounds before engulfing the dark pink, succulent nipple in her mouth.
"Mmm, tasty. You always have such delicious meat."
"You always say the sweetest things. Hurry up and swallow me already."
Abby doesn't hesitate. She stretches her mouth wide, engulfing her sister's dark-haired head and slim pale shoulders. A couple of gulps drag Zoe's luscious full breasts into the mouth of her sister, who licks and savours them before moving on to the stretched, soft, wiggiling belly. The large, taut orb is tasted thoroughly, then squeezed inch by inch into the predator's powerful throat, and Zoe feels herself getting wet from having her tummy played with like that. She feels Abby's hands stripping off her pants and panties, then a finger sliding over her pussy, then inside it. A gush of wetness rewards soon rewards its ministrations. By now Abby has engulfed her tasty sister's ample vore gut almost entirely, the sizable orb stretching her own neck into a person-sized bulge. She gulps again, bringing her sisters toned pale ass and sopping pussy into her mouth, and proceeds to give them both an ample licking. The orgasmic taste of her sister's ample juices spills across her tongue, encouraging her to lick both deeper and harder. As Zoe climaxes, she screams inside her sister's throat and thrashes against its tight grip. This prompts a powerful peristaltic contraction from the muscles, which squeeze the girl and press her towards the stomach. The bulge in Abby's neck moves towards her stomach, stretching it from flat to larger than person-sized in seconds and Zoe's shapely kicking legs vanish between Abby's red lips like a pair of noodles, Zoe's pink-nailed toes still curled from orgasm. As Zoe slides into Abby's belly, she is dumped headfirst into a large puddle of stomach acid and warm coke. The walls, wrinkled and slimy, squeeze her nubile form into a foetal position as she wriggles and tries to sit up. Finally, she manages it, curling up in the slimy, fleshy sack with her legs pressed to the sides of her gut and her arms by her sides, covered up to her neck on the soda-and-enzyme mixture.
"Fair warning sis", she hears Abby call out from above. "I'm pretty hungry, so I should digest you rather fast."
Zoe is left alone in the dark, listening to the gurgle and growl of her sister's intestine and digesting her meal even as her own flesh tingles and softens from Abby's stomach acids.
