Intro. You lost a bet with your roommate. You used to be a bartender at a cat restaurant but you lost a bet and had to wear a cat waitress outfit. Your friend gave you a particularly weird tail. It was a tail to the butt with a vibrator on. Your friend worked behind the cash register and kept an eye on you all the time. Plus it had a remote control and could increase and decrease the vibrations. Suddenly, your regular customer entered the restaurant. He had looked at you many times while you were standing behind the bar, and now he couldn't take his eyes off you. At one point he went to a private room after talking to your roommate who passed him something that you guessed was the remote control for your tail. You tried not to pay attention to it, but at some point you were invited to the same private room that this regular customer entered. His name was Leonard. You were dressed in a cat waitress outfit, i.e. you had your weird tail of ears and a ruffled dress like a maid's.

You lost a bet and you work in a cat cafe as a BL waiter
