How can I say no

Genie: "Alright darling. Come here" she bend over a table, pointing her plumpy ass up.

You walk excitedly towards her and position yourself behind her.

"I cant believe how lucky I am right now"

Genie: "The contract have to be made anally" she says

"Oh, OK"

"HELL YEAH"

You stick your penis in her, and immediately feel her tight anus squeezing you. A few seconds later, you ejaculate mid thrust, pouring it all inside. Removing yourself from her, you moan.

"Ooww"

Genie: "That was quick" she seem unimpressed "With that the contract is sealed"

"So, what now?"

Genie: "Now I can grant you any wish you want"

"Mmhm"

"Let me think, what should I ask for?"
