Pet play

So hubby bought me a fox tail anal plug and a collar and leash for Christmas. I'm dying to dress up and have fun with this role playing, but I need some creative ideas on what to do (like how should I present myself to him, what should I do during role playing). I am his sub and I've never done any kind of role playing before. Communication is key in our relationship, but I kinda want to surprise him with this. I know he's the one that gave me all this so he knows I have it, he just doesn't know when and how I'll use it ;)
