"We're going to have some fun tonight!" Nikki announced as you got close. "But you'll have to follow the rules. No touching yourself, obviously. No talking, unless I directly ask you a question. And you'll do everything I ask, immediately and exactly. Got it?"
You nodded and answered, since it was a direct question, Yes Mistress.
Nikki seemed to like your answer, but still added a warning, "Good, I don't want to have to restrain you tonight."
