Kathleen was huffing and puffing, red and sweaty. One hand was holding her back, as the other clutched the underside of her huge belly.

It was an unbelievable sight and sure to be the next small-town scandal. Tears were forming at the corners of her eyes as she tried to bear the strain and also gather her composure.

The dress was still sliding, her plump ass starting to protrude from the back. It revealed that she was wearing a dark red thong! But then, the local department stores probably didn’t have her size at this point. A thong was likely the only thing left that could accommodate her wide hips and gigantic ass.

One of Kathleen’s dress straps snapped right off. She clutched the material as her heaving cleavage grew all the more prominent. She looked absolutely mortified, yet panicked and speechless, as the dress strained and more of her flesh became exposed.

The other church-goers were gawking, positively appalled. Jade looked around at them. “Mom had a big lunch,” she said wryly. It was a tasteless joke but Jade seemed to be enjoying herself. “She’s insatiable for food. Well, for a lot of stuff,” Jade added nastily as she patted Kathleen’s massive, heaving belly.

“We actually have to go,” Jack blurted to the increasingly offended congregation members. “It was good, er, seeing you all.”

With that, Jack and Jade took places at Kathleen’s flanks and ushered her off even as the crowd grew around them. She was panting heavily like she was doing lamaze as they ushered her out of the church doors and into the parking lot.

They didn’t even attempt to get Kathleen into the back seat. She wasn’t going to fit. Jade grudgingly let her have the passenger seat, which was adjusted back and lowered so Kathleen could have sufficient space for her belly. Still, it prodded the dashboard at times when there were bumps in the road. Kathleen was moaning while desperately rubbing her swell. It was nearly the size of a beach ball. The scene was uncomfortably lurid. But Jack kept his eyes on the road.

“God, I just bought this dress the other day,” Kathleen moaned. “Nothing else is going to fit me. Mmgghhhh…I’m so hungry.” Her belly rumbled.

Jack made a quick stop at a fast food drive-thru where he ordered two bags full of greasy burgers and handed them over to Kathleen. The older woman immediately got to work, tearing off wrappings, chomping through burgers voraciously with no attempt at her usual etiquette.

Was Jack imagining it, or was that dress getting even tighter? More and more of her skin seemed to be steadily becoming exposed. Jack pulled into the parking garage entrance of the mall. There was a popular maternity store here. “Jade, you want to run in and grab your mother something to wear?” he asked, a bit desperate.

A glance through the rearview mirror revealed his wife glaring back at him from the back seat. They had a silent staring match until Jade finally huffed, “fine.” She had little discretion when it came to her resentment for her mother.

Jack sighed as Jade got out of the car. He drummed his fingers on the steering wheel as he waited. Kathleen was back to squirming and moaning, hands rubbing into whatever she could reach of her swollen abdomen. Jack just tried to keep his eyes forward.

Finally, Jade hopped back into the vehicle, shopping bag in hand. “Got something,” she said as she sipped a soda. “Biggest size. They said it’s stretchy.”

“Great,” said Jack, starting the car. With that, they went home.

The dress certainly was stretchy. It was a bodycon dress, something light, perhaps for the beach. It was long, spandex, and clearly too small, yet somehow Kathleen made do. But then, she didn’t have a wealth of options.

And it was so truly tight, hugging every curve and contour of her body. Interestingly, it was flesh-colored. She almost looked nude. Well she practically was. The material was stretched to near transparency, and Jack could make out the crease of her ass and pink splotches that were her swollen nipples bulging prominently against the material. It was practically obscene.

You started it, Jack reminded himself. If he took issue with Kathleen’s attire, that was entirely his fault. He would have to check for alternatives online. Maybe they could order something roomy; more customized.

“Thanks for taking care of me like this. I just don’t know what’s going on,” Kathleen rambled, still all flustered and breathless, her huge breasts bulging heavily from the deep V-neck. She was perched on the couch, huge belly on her lap, rising and falling, just looking absurdly massive. “Ngghhh, god, this baby is huge,” she griped, words going muffled as she chomped on a forkful of lo mein.

Kathleen swallowed the food, grimaced, then gave a loud belch. She whined and squirmed, cupping the swell. This was just nuts.

“This pregnancy doesn’t feel normal,” Kathleen whined. Another burp. “I should see a doctor.”

“I am a doctor,” Jack reminded her as he opened a kitchen cupboard, wondering when Jade would be home. She had slinked off to her pilates class, leaving him to suffer.

“Ohhhhh…”

Jack spun to see Kathleen arching on the couch, belly swelling, pushing out. She was flushed and sweaty, panting and fanning herself. “Oh god…” she groaned out, shifting her hips. Her belly sunk slightly, tension mitigating, then began to rise again, inflating like dough. “I c-can’t…nrrrgghhhh…Jaccckkkk…”
