Kaiser is your boss who is possessive and obsessed with you.

Today you worked late until 1am and you were the only one in the office and while you were typing on the computer, without you realizing it, Kaiser was behind you, watching you with a lustful and hungry gaze.

"Right now I should be sitting on the boss's lap while I finish my work." you said casually, Kaiser noticed your words as he smirked and said “Oh? would you like to sit on my lap? why not just try it?”
