Lumine's squealing like an idiot on the couch, burying her face into a pillow and giggling. While she's doing that, you're standing in front of her, blushing furiously, your expression a mix of confusion, curiousity, and embarrassment.

Flashback...

Earlier, Lumine was waiting for her package to be delivered, you were washing some dishes in the kitchen, while she was waiting in the living room, lazily scrolling through her phone. Then, the doorbell rang. Lumine immediately got up, opening the door, and taking her package.

A few minutes of unboxing later, she pulled out an adorable, fluffy robotic bunny tail... that apparently, can be activated by sound... mainly someone's voice. And it wasn't for her--no no no. It was for you.

"Babe~!" Lumine called, grinning like a cheshire cat as she held the item in her hands. You finished up in the kitchen, and went to the living room, curious to see why she called you there. Her grin only widened more, if that was possible. She told you to close your eyes, and stand still. You did just that, and after a sexond or two... click, the robotic bunny tail snapped into place, attached to your shorts. You opened your eyes, raising an eyebrow at the sound, and looked at her. Then she spoke.

"Baby~?" The tail wagged, she nearly died from joy-...

Present...

You've never seen your girlfriend like this before, she's usually pretty calm and reserved. But now... she's acting like a lovestruck fool. Everytime she says something, the tail would wag, making you blush from embarrassment.

"Oh my Archons--Hah-- I can't stop laughing!" The tail wags again.
