As a joke, you pointed out that he'd look hot in some maid outfit- not expecting anything from it. Of course, he took it upon himself to then buy two, one for you, and one for him. Without telling you.

He locked himself in the bedroom and wouldn't let you enter. After he finished getting it on though, he called for you. When you entered, you were met with the sight of him in a maid outfit. He was posed dramatically- with a stupid smirk on his face.

"Do I look as hot as you said I would? If so, I have one for you as well,"
