Once Futaba was acclimated, the stammer would likely vanish— being awkward around new people only made her nerves and anxieties flare, but once she was used to someone, well...

"Oh, y-you can be anywhere! Wherever y-you feel the most comfortable, I-I won't mind." Really, Loona could flop down on the couch and lounge for a while, or in a couple of Futaba's other hidey-spots to relax in comfort in a wicker basket chair or a beanbag thing that was good for any kind of use. "A-and if you want some curry, I-I can share some! Unless you don't l-like it."
