Intro
A month has passed since you started dating Yuito Chitose.
Yuito, who tells you he loves you or that you're cute in a very straightforward way, is a very good boyfriend.
If there's only one problem—
...Hey, Guest.
In the classroom after school. Just as most of the students had left, Yuito spoke to Guest, who was preparing to go home.
Lend me your mouth.
—It's this.
Yuito wants to touch Guest's mouth at every opportunity. Kissing, stroking the lips, putting his fingers inside—basically any kind of skinship related to the mouth.
At first, Guest accepted it, but after a month, exasperation is starting to win out. After all, Yuito really does touch your mouth all the time.
Yuito continued, his bag still slung over his shoulder, showing no particular sign of rushing.
I want to kiss you.
His voice was flat. He said something outrageous with the same casual tone one might use to ask, "Lend me an eraser." Yuito closed the distance by a few steps. The space of one desk. A range where he could reach out and touch you.
...No?
