Selina stopped for a moment, not sure what to expect. The first thing she noticed was the smell. Oh god, the smell. It could best be described as a putrid combination of sweat, methane, rotting food, and human waste. It was overpowering, and it hung in the air like a thick fog. Selina gagged, instantly regretting her decision, and tried to open the door. To her surprise, it had locked after closing, and a reinforced steel bolt and hinges implied that it was meant to stay that way. Refusing to accept her fate, Selina rattled the knob, which (unsurprisingly) not budge a bit. She kicked it as hard as she could, only to feel a blinding jolt of pain shoot up her leg. If her ankle wasn't sprained before, it was now. After a moment for it to sink in, Selina finally accepted the fact that she was stuck in here.
Turning around, she noticed some minor details, such as the fact that the floor was knee-deep in some foul brown murk (whose contents she did not wish to learn), the massive amount of what seemed to be mold spores saturating the room, and a revolting noise that sounded like a clogged garbage disposal on a pig farm. Cautiously, Selina lowered herself into the foul stew and waded through the hazy air, following the noise. She inched closer and closer, grimacing at the feeling of the sludge around her seeping in through seams in her outfit. Selina eventually noticed a vague outline ahead of her; she initially ran, but winced and remembered her sprained ankle, finally resorting to a slow jog.
From a distance, Selina saw what seemed to be a giant mound of rotting food and excrement; as she edged closer, Selina realized that it was a massive sleeping woman. Her skin was almost entirely covered in a thick coating of decaying food, sweat, and skin oil, all anchored by a thick web of body hair. A gargantuan gut, its front stacked with half a dozen rolls as thick as Selina herself, stuck forward by eight feet and was almost as tall. Two pillow-sized breasts with nipples large beyond all reason hung ponderously at its sides. Thick piles of love handles forced her tree-trunk arms to be almost perpendicular to her torso. Circling around, Selina gaped in awe at the two massive balls of lard that constituted the woman's rear. They were constantly vibrating from the rumbling of a swollen sphincter the size of Selina's head, pumping nigh-endless amounts of feces and methane into a large, clear pipe rammed deep inside. Only the faintest outline of cow-sized calves and thunder thighs could be seen in the brown murk. Atop the mountain of adipose lay a face concealed by a pile of decaying food, thick cheeks, and a dozen chins that wobbled profusely with every snore. Her mouth was mindlessly occupied by a large hose hanging from the ceiling, dispensing a sludge that certainly did not look edible. A rat's nest of tangled, greasy black hair ran several feet long down her back and vanished deep inside her canyon-like ass crack.
Selina was so shocked she could barely speak. "...D-Diana?"
The massive blob snapped out of her sleep, stopped her absentminded suckling, and held her fart in long enough to glance through the fumes. "Selinah? Is thayat yewURRP hun?" she replied with an incredibly unusual thick Southern drawl. "Oh mah gawd, it's the Fayat BRAAPCayat herseylf! But ye're so thin, hun! Did yew fahll fer PRRRFT oneah them diet scayams, ya poor thang?" She certainly sounded very sweet and almost motherly with both her accent and her concern for Selina. Diana pressed a button on a small remove controller in her hand, prompting a video screen to extend down from the ceiling. "And it sayahs here that yer hormones 'n' skeleton 'r' all fucked up. MaybePRRBSPLT yew should get a dose of thayat treatment. Ye'll be bUUHP back to yer old self in no time!"
Selina pondered whether or not to go along for a moment. On one hand, it could be her only method of getting out and finding out what happened at this point, but on the other, she could end up like Diana...
