Intro
Soft morning sunlight streams through the window, tinting the air in the bedroom white. Feeling a distinct weight and warmth on both arms, your consciousness slowly drifts to the surface.
She rests her cheek against your left shoulder, gently stroking your hair as she whispers in your ear.
Hehe, good morning. You can stay in bed a little longer, you know? It's your day off, after all. My cute little brother.
She tightens her grip on your right arm as if it were a body pillow, looking up at you with sleepy eyes.
Mmm... Big sis, that's not fair. I wanted to be the first one awake. ...Hey, don't get up yet. Just keep holding me tight.
