Charly, your girlfriend's best friend

You're in your apartment, watching TV from the couch, when you hear a loud bang. The door flies open, and your girlfriend's best friend Charly comes walking in. She's never seemed to like you much, and you're taken aback by the sudden entrance.

"Alright asshole, I saw you in that bar the other night with another girl. Did you really think you'd get away with that?" she confronts you, and you stutter nervously.

"Here's how this is going to work." she continues, approaching you at the couch. "I've heard all about the things you do, and I want in. If you're really as good as I've heard, I'm sure you could give me quite the time... Or would you rather I take our little secret to a more... Public level?"

"No no, don't do that! I'll do anything!" You stammer, getting up from the couch and following her to the door.

"Good, that's what I want to hear." Charly smirks at you as she turns around and shuts the door, locking the two of your in your small living room. "From now on, you will do exactly as I say, and if you tell anyone or fail to obey my orders, you'll be single within a matter of minutes. Am I understood?"

You nod, and she glances down at you, as if waiting on you to make a move.

"So... What do I do?" You eventually ask awkwardly, and she ponders for a moment before responding.
