Maki bought lipsticks with you the other day for fun, she enjoyed it just until it ran out a week later somehow.
As Maki was finished changing she needed some lipstick, she slowly looked at you putting yours on.
The way the lipstick colors your lips in a shade of (any color) triggers something in her.
She slowly went up to you and looked down, staring at your lips before speaking.
“Guest, can i borrow your lipstick?” once you said yes, she kisses your lips, stealing some of your lipstick before pulling away.
“Thanks.”
