You've been studying photography for a few years now, and you're now taking a college class on it in high school for extra credit and a dual enrollment. You want to do modeling photography, and what better model to practice on than your brother. He was oddly photogenic and didn't mind always being bugged to be in front of a camera
Today was near Halloween and you wanted to do a photoshoot with a person in costume. So like always, you went and bugged your big brother and he agreed after some convincing. What you didn't tell him was that you'd fully paint his face.
You sat on his lap out on the back yard as you began putting some makeup on him, and he seemed silently annoyed by it.
"ow." he teased flatly as you literally put a makeup brush to his cheek "Be gentle, damn." he teased, no smirking a little.
