The dungeon air was damp and cold.

Airi adjusted her staff, her long braid shifting over her shoulder. Her dark skin caught the glow as she stared at the massive shape blocking the corridor ahead.

It was a monster made of cake.

Its body was layered sponge and frosting, but its face was wrong—too wide, too sharp, a mouth lined with jagged teeth that opened like a furnace.

Neko tilted her head slightly, cat ears twitching. Her black dress and twin pigtails shifted as she stepped forward.

Airi frowned. “That thing looks strong. Don’t let your guard down or it’ll take your life.”

Neko glanced at it and sniffed the air.

“…It smells kind of tasty.”

Airi shot her a look. “Neko, don’t say careless things like that.”

A glowing beam formed in its mouth.

Airi blinked once—she wasn’t paying attention.

“Neko—watch out!”

Neko reacted instantly, shoving Airi aside.

The beam struck her directly in the mouth.

“Ah—!”

Warm pressure spread through her body as if something had been poured inside her stomach.

“…What is this feeling?”

Her belly began to expand rapidly, pushing outward like dough being filled from within.

Airi froze. “Neko?!”

Within seconds, Neko’s belly swelled into a large, heavy sphere—her body shifting out of proportion as the cake accumulated.

Then the change stabilized.

She was already close to 600 pounds, her lower body rooted to the ground, dress stretched tightly across her expanded frame.

Airi stepped forward, shocked. “Are you joking?! Her body…”

Neko looked down, breathing unevenly. “I didn’t… expect this…”

Airi’s expression hardened. “Her body became that bloated in an instant… just from protecting me.”

Airi’s eyes narrowed. “How dare you do that to my partner!”

The monster fired again.

“Airi! Behind you!” Neko shouted.

Too late.

The beam struck Airi mid-motion.

“Ah—!”

Her body reacted exactly the same.

Warm pressure flooded her belly as her form began expanding rapidly. Her clothes strained immediately as her frame widened, matching Neko’s scale within seconds.

600 pounds.

Then slightly beyond.

Airi staggered, grabbing her staff to stay upright. One hand pressed against her thigh, the other against her growing belly.

“…T-this is bad,” she muttered, breath tightening as the beam continued. “It’s pouring into my belly… it’s not stopping.”

Neko, still stabilized in her massive form, shifted unsteadily and pressed a hand against Airi’s belly just to keep balance.

Both were now being affected at once—the beam feeding them continuously, transferring cake mass into their bodies like forced digestion.

Airi grit her teeth. “If I become any heavier than this, I won’t be able to—”

The monster lunged forward again.

Neko moved first.

She opened her mouth and bit into it.

Airi froze. “…Huh?”

The monster screamed.

Neko grabbed it, pulling chunks of cake directly into her mouth, chewing with growing urgency.

“What are you doing?!” Airi shouted.

Neko swallowed and grabbed another piece. “No… I think it’s edible!”

Airi stared in disbelief. “You’re…eating it?”

The monster thrashed as Neko continued consuming it, her body growing heavier with every bite.

2000 pounds.

Her clothes finally gave way under the pressure, but she didn’t stop. She simply kept eating, hands digging into the monster’s body, pulling it apart like it was food meant for her.

Airi stood frozen, still swollen and struggling to balance her own transformed weight.

Neko continued.

3000 pounds.

The monster shrieked again, now reduced in size.

Airi looked between them. “Neko… stop before—”

She finished it.

The last piece—a small screaming crumb—was swallowed.

Neko collapsed forward into a massive, motionless form.

Over 5000 pounds.

A giant, resting shape of pure fullness and exhaustion.

Airi slowly lowered herself beside her, still heavy, still unstable.

“…You really ate all of it,” Airi said quietly.

Neko’s spoke.

“Yeah…”

“My whole body feels big and heavy… I can’t move at all.”

Airi looked at her.

“But… my belly is full. And I’m happy I got to eat cake.” Said Neko.
