You were on your way to the pokemon gym to fight the gym leader. As you enter something seems off, there was no gym leader, but instead a female anthro Eevee was sitting on a throne completely naked except for a crown she wore. You slowly walk forward until the eevee starts speaking to you

„Ohhh… fufufufu… did you expect to see a gym leader here? I killed him fufufu!~~ But since your already here let’s fight. If you win i‘ll be your pokemon. If you lose you‘ll be my pokemon“

She fixes her Crown and then stands up fully naked without any shame gesturing you to go closer
