“Grandma’s Got Bills to Pay" - Momo and Seiko Edition (Part 1/2) (Patreon)

Late afternoon sun spilled across the tatami in lazy gold bands, warming the living room.

Momo padded through on her way to the kitchen, half-awake and intent on grabbing a drink and disappearing again.

As she passed behind her, Seiko’s head tilted slightly.

“Roof guy called again. Wants another two hundred thousand yen just to patch the latest crack properly. And the plumber says he’ll charge extra if we don’t deal with that pipe before the next rain.”

Momo slowed, then turned with a frown.

“…Okay? So sell some of your weird occult junk. I’m not working at the konbini again.”

Seiko finally looked up over her glasses, the corner of her mouth lifting.

“I’ve got something better. An old acquaintance runs private photosets. Artistic. Pays cash—half upfront, rest on delivery. Enough to cover the roof, the pipe, and maybe even that console you keep staring at.”

Momo blinked. Then blinked again.

“…Photosets. Like… modeling?”

“And I told him I’d bring my granddaughter. Double the pay if it’s a duo. Chemistry sells.”

Momo took one step back on instinct.

“Me? No. Absolutely not. What is it—swimsuits? Lingerie? I’m not—”

Seiko waved a hand, cutting her off with a soft laugh, and patted the tatami beside her like.

“Starts simple. Clothes on. Cute poses.Tasteful. Professional.”

Momo crossed her arms tighter. “This is emotional blackmail.”

“It’s economics,” Seiko replied, perfectly unrepentant. “You want to keep living somewhere rain doesn’t drip into your noodles?”

Momo through gritted teeth: “Fine. But only because I’m sick of mopping. And if anyone from school ever sees these, I’m telling them you’re a perverted ghost who possessed my body.”

Behind her, Seiko leaned back on her hands with a satisfied little smirk.

“That’s my girl.”

The softboxes warmed the brick wall to honey, and the photographer lowered the camera with a satisfied hum.

“That’s a wrap on the bikini set. Perfect chemistry,” he said, thumbs up.

Seiko hoisted Momo onto her hip like she’d won a prize. Flash. Click. Both of them laughing, the whole thing annoyingly photogenic.

Momo slid down, cheeks flushed and hair slightly feral.

“…Okay. That was—ugh—fine. Kinda fun. But we’re done now, right?”

She turned toward their clothes.

“Not quite, sweetheart.”

Momo froze mid-reach. “No.”

“There’s extra cash on the table. Big extra. Roof. Pipes. Your console. And enough left over for snacks that don’t taste like regret.”

Momo narrowed her eyes. “What’s the catch.”

Seiko’s smile went sly. “A second set. The fun one.”

The photographer cleared his throat and slid a clipboard forward like he was presenting sacred scripture.“It’s tasteful. Artistic. Duo poses—intimate but elegant. Nothing crude,” he said quickly.

Momo stared at the clipboard, then at Seiko’s sparkling, unapologetic grin, the promise of real money and the surprisingly enjoyable vibe from the first set finally wearing down her last defenses.

“You’re literally the devil in red glasses. Fine. Let’s do it—but if I start enjoying this too much, I’m blaming you forever.” Seiko’s eyes lit up with pure triumph as she stepped closer, fingers already teasing the ties of her bikini top.

“That’s the spirit. Now let’s make it worth every yen and have a little fun while we’re at it.”

-------

They posed together with growing confidence: backs pressed to the wall, arms linked, laughing as they struck exaggerated pin-up angles.The photographer murmured constant praise—“Gorgeous, natural, keep that energy”—and the shutter clicked in a steady, almost soothing rhythm.

Then the energy dipped. Momo let out a long breath, pushing damp hair off her forehead.“Okay… I’m tapped. That was more than I signed up for. Let’s call it, Grandma. I need a shower".

Seiko’s hand landed gently but firmly on her shoulder, holding her in place. Seiko’s expression was soft, almost fond, but there was a glint in her eyes that Momo knew too well—trouble.

“I made another deal with him while you were changing earlier. One I couldn’t say no to. Triple the original payout—enough to fix the whole damn house top to bottom and still have a fat stack left for both of us. But it comes with a little… bonus round.”

Momo’s eyes widened slowly. She glanced past Seiko - “You… you didn’t.”
