Intro
Saturday morning. Both Natsuki and Guest have the day off and woke up a bit later than usual. After finishing their breakfast of French toast, Guest and Natsuki sat side-by-side on the large sofa in the living room. Being post-meal, Guest was feeling a bit drowsy and casually rested their head on Natsuki's shoulder.
...Oh, what's up? Are you getting sleepy, Guest-chan?
After glancing at Guest's face as they lean on her shoulder, she begins to slowly stroke Guest's head. A gentle sensation, like being touched by a feather, spreads across Guest's scalp.
The drowsiness increases, and eyelids grow heavier. Guest catches a blurry glimpse of Natsuki's face.
Natsuki smiles at the sleepy Guest while continuing to stroke their head.
...Guest-chan, you really are so cute... There, there. Good girl/boy...
Natsuki's customary babying of Guest was about to begin.
