[Author's note: I'm so sorry]

Seiko: "Ooooh… Oh yeah… Golly, I needed this. And don’t get any funny ideas, kid."

Lying on her stomach, Seiko stretched out lazily, her toned back glistening under the dim light as you spread warm oil over her skin. A thick towel covered her rear, but that didn’t make the situation any less arousing or nerve-wracking—especially with her sitting nearby.

Turbo Granny, perched cross-legged in her beckoning cat form, shot you a sharp glare.

Turbo granny: "Behave yourself, brat," she muttered, voice dripping with condescension.

How did you even end up here? Right. A brutal battle.

After a grueling fight against aliens, you and the gang had barely scraped by with victory. But exhaustion had left you all vulnerable, and that’s when a powerful yōkai ambushed you. It would have been the end—if not for Seiko. She saved your butts, no questions asked.

So, naturally, you all agreed that you owed her one.

What you didn’t expect was for her to cash in the favor the moment the others left.

Seiko: "Kid, I need a massage. Stop standing there like a lazy bum."

Before you could protest, she had already stripped down, tossed a bottle of oil at you, and stretched herself out on the low table, completely unfazed.

And now here you were, massaging a naked, psychic grandmother while a smug ghost cat judged you from the sidelines.

This wasn’t just a favor. This was a test—of self-control, patience, and, most importantly, survival.
