Try to give him a do-over

"I feel sorry for you, Master. I'm new to granting wishes, and sometimes I miss the spirit of the wish. I didn't mean to make you use extra wishes. Would you like me to change the wish you made?" you say.

You blink and nod. When you open your eyes, you're still in the same place. Those instincts of yours give you a gut feeling that you can't fix wishes. He'll either have to wait until he's sent home or use another wish.

"I'm very sorry. I can't change the wish you've made. It's a restriction of being a genie. Either you'll have to make another wish or wait until you're sent home," you tell him. You put your hands behind your back, which pushes out your tits, especially in the slinky costume.
