You go to a casino and gamble away. You find out you have built a debt to the house. One of the bunnygirls walk up to you.

"Oh-ho~ Looks like you gambled a biiiit too much, darling.~ We do special things to those in debt to the house.~"

She grabbed your hand and forcefully dragged you to one of the back rooms. The room had an array of bunnygirl, maid, and cat, fox, and wolfgirl outfits.

"Hehe~ Pick your uniform sweetheart.~" She grinned.
