The Tube bus came to a smooth, quiet stop in front of the entrance to the apartment complex. After a few seconds' delay to set the brakes, a ramp lowered and the side of the bus opened upward, supported by a slightly squeaky hydraulic arm on each end. On an ordinary Tube bus, a smaller door or hatch would have sufficed to let the passengers disembark. The larger opening was needed, not only for the cargo being transported, but also for one particular passenger.

Slowly, a round form was rolled down the loading ramp. The smooth, goosebump-covered texture of her skin was covered intermittently by stripes of red silicone, each about twenty centimeters wide. One encircled her waist like a girdle; another reached from front to back, covering her lower meridian and keeping her more or less decent. The two other straps went over what used to be her shoulders, covering her nipples like a judiciously placed pair of suspenders.

Apart from preserving Sandra's modesty, the rubber straps also helped Jeri keep a grip on her as they exited the Tube bus. Anywhere else, Sandra would have been mortified to be seen outdoors with so much of her inflated body visible. But one of the benefits of this place was that she wasn't the only one stuck in a bloated state.

Behind the two women, another round shape came slowly down the ramp - this one made of injection-molded cellulose. The two-meter diameter globe was being carefully rolled by Caiden, a friend of Jeri's who now worked at the hospital. When Sandra's spot on the waiting list came up sooner than expected, they decided to go in for her biannual checkup a few months early. After all, there was no need to call for a bariatric bus an extra time, purely for the sake of maintaining a strict schedule. Caiden had been on shift when they arrived, and had offered to help with the move in exchange for dinner.

"Good morning!"

The cheerful, melodious voice was unfamiliar. Jeri peered around her girlfriend's side to find a short, curly-haired woman in a maternity dress smiling at her. "Uh, hi! Good morning."

The short woman gave a brief wave before resting her hands on her large, spherical belly. "Sorry, didn't mean to startle. Name's Caroline. I guess you're my new neighbors?"

"Oh, yeah!" Jeri smiled back, rolling her partner forward so she could see. "I'm Jeri, this is Sandra. Babe, this is Caroline."

Sandra wiggled her fingers in her best approximation of a wave. "Nice to meet you. Forgive my not shaking hands."

"That's quite all right," she chuckled. "What's that your friend's pushing?"

Caiden pulled the globe to a stop on the soft pavement. "It's a Taärgus—you know, the storage unit. Got another one we need to unload."

"Oh! Do you need some help?"

"No," Jeri replied reflexively. "It's pretty heavy, you probably shouldn't strain yourself in your... condition..."

Caroline's laugh was like the staccato clack-clack of an old mechanical keyboard. "I'm not pregnant." She slapped her tummy twice, making a noise like a rubber kickball. "Tumeotoxin syndrome, type B. I'm guessing you're type A, Sandra?"

"Y...yeah." Strangers inquiring after her medical history usually rubbed Sandra the wrong way, but at least this ask came from someone in a similar boat as her.

"C'mon, I'll give you a hand." Caroline trotted up the loading ramp, then started rolling the second Taärgus out, one hand firmly gripping a recessed handle. "What unit are y'all in?"

Jedi glanced at her tablet. "Building 12, Apt 104."

"Oh, cool! That's one of the newer buildings, I think. Just went up last year." She was on firmer footing as she returned to the soft pavement, but she had to walk almost sideways to avoid bumping the spherical crate with her belly.

The three mobile humans rolled the spheres up to the arched double-doors of the conapt, where Jeri sighed and fanned herself. "I think me and Caiden can take it from here. Thank you so much for your help, Caroline."

"Oh, it's no trouble at all! Hey, I've got a casserole in the oven. Do y'all eat dairy?"

Caiden nodded quickly. "Sure!"

Caroline beamed. "Super! I know you've probably got a lot of unpacking to do, so I'll just drop some off in a half-hour or so." She waved to Sandra, whose head was sideways in her present position. "Nice meeting you all!"

Jeri and Caiden waved back; the latter's hand was still half-raised when Caroline finally waddled out of sight. Jeri smirked, and Caiden flushed slightly.

"...What?"

* * * *

Two hours later, one of the Taärgus units was fully unpacked, and several large pieces of casserole had been eaten—mostly by Jeri and Caiden, as Sandra had only a few bites before settling in for a nap. Jeri hugged her friend and said goodbye, then went into the narrow living room. Sandra was resting, nude, on the only piece of furniture already included with the conapt: a circular cushion about four feet in diameter, its center recessed like a shallow bowl.

"Hey, babe?" Jeri patted her girlfriend's side—gently, so as not to set off uncomfortable echoes within her body.

The ballooned woman's eyelids twitched, then cracked open groggily.

"Sorry, but you asked me to wake you after lunch."

"Yeah... yeah, I did." She yawned, wiggling her fingers. "I'm gonna try out the shower. You wanna do anything after?"

Jeri nodded, resisting the instinct to bite her lip. "If you're still up for it, yeah."

With a wink, Sandra stretched her hand toward the rope running along the wall like a banister. Her grip secured, she pushed off to the wall on the other side, her puffy fingers closing around that rope as well. While Jeri stood to one side, Sandra began to pull herself along the room, scooting on her belly like a Baikal seal. Undignified though it may have looked to the outside observer, it was better than having someone else roll her around everywhere.

After what felt like half an hour of pulling her entire body weight using only her hands and wrists, she reached the bathroom and bounced awkwardly into the oversized shower. An array of large buttons covered in vinyl were mounted on the far wall; with a press of the first button, the frosted shower door slid shut on well-greased rollers. Another button press turned on the overhead sprayer, the hot water pouring out at deliberately low pressure; another did the same for the sprayer in the bottom corner.

Following a few minutes to confirm the water was warm enough, Sandra pressed another button and the sprayers began to move back and forth—the top one moving left as the bottom one moved right, and vice versa. Another press, and the water was joined by a spray of all-purpose liquid: shampoo, conditioner, and soap in one easy application. The water soon rinsed the suds away, leaving her hair dripping.

Finally, she shut the sprayers off; as they returned to their middle positions, she turned on the overhead blow-dry fan. Rivulets of water ran down her sides, most evaporating from the heat before they reached the drain; and soon she was mostly dry.

The whole process took just under half an hour—longer than she liked to spend in the shower before getting stuck like this, but quicker than having Jeri give her a sponge bath with moist towelettes. Sandra pushed the button that slid the shower door open again, and began scooting down the hallway—this time toward the bedroom.

"Hey, cutie." Reclining sideways on the large mattress was Jeri, clad in matching bralette and panties, in that electric blue that complimented her fiery hair so perfectly.

Sandra bit her lip. "God, you look good." She wiggled her hands again. "Wanna carry me to the bed?"

Jeri chuckled and stood up, her hips swaying as she slowly walked over. Her fingertips searched Sandra's distended middle for the spots where her hips used to be, gently squeezing there as she rolled her across the room to the mattress. Pushing her so their heads were level, Jeri leaned in for a passionate kiss, drawing a surprised moan from her girlfriend. The kiss seemed to blot out the world around them, and when Sandra tipped her head forward to nibble at Jeri's lip, the smaller woman felt desire bloom in her like an explosion of rose petals.

Reluctantly, Jeri pulled away, resting her hand on Sandra's body as she took a shaky breath. "I'd really like another taste of you... but lower."

"So long as I get to return the favor." The inflated girl licked her lips. "Just..."

"Hmm? What is it, babe?"

Now it was Sandra's turn for an unsteady breath. "I kinda want it to be... normal? Like old times." Her gaze moved downward, where she could only see to the horizon of her spherical form. "As if I wasn't stuck like this."

Jeri's expression softened. She felt tears welling up, but blinked them back in favor of a slightly forced-feeling smirk. "So you just wanna be the hottest piece of ass I've ever taken home? I think I can manage that."

The kisses resumed, a series of quick pecks that slowly moved lower—from Sandra's mouth to her chin, to the patch of freckles that marked what used to be her cleavage. Lower still, to her upper belly; to her navel, stretched almost flat by the pressure within her. Jeri used to tease Sandra about inserting an air hose into it like a valve, which had always made Sandra whimper and squirm.

Tempted as she was, though, Jeri didn't linger; another brief lick, and she began to dip her head lower still. The short hairs of Sandra's pleasure trail, carefully cut with an electric safety trimmer,
