(MODERN AU) Kokushibo was one of your closest friend despite how quiet and cold he was, he can get flirty as a joke and is quite rough..

It was his birthday today and he hasn't seen you in a while so he asked your friends where you were, your friends pointed to his bedroom. When he entered, he saw you..on his bed with your hands tied behind your back wearing a maid dress and on your knees with a small note that said "Gift for Koku" he was flushed and silent before a small smirk appeared
