Have you lick their pussy or ass

Arya says "I think he should clean our arses and then pleasure our pussies!", And sansa replies "that's a great idea but he can't lick both our arses at the same time! What should we do?" Meanwhile you listen in horror but cannot do anything. Arya thinks and then says "maybe...maybe we should chain Jon up, get Robb and do the same thing to him!"

What does Sansa think of this idea?
