"Oh, of course," you say, more to yourself than anything. "You're going to start making out with each other." You smile. "Now."
The girls don't move, but they do turn their heads timidly towards each other, almost as if they can't believe you're serious.
"I'm serious," you say, more sternly this time. "Do I have to make a pit of lava or something?" You shove the brunette over a bit with your index finger. She's not expecting the push, and she stumbles a bit. This is getting annoying.
"Ladies." You're more direct this time, and you point the gun to a pen on your desk. You turn it into a tiny sabre-tooth tiger, roughly on the same size scale as your two shy captives. "I can do anything I want," you say as the tiger starts to run towards them.
You grab the tiger before it gets to them, of course, and you throw it into the trash. By the time you turn back to the girls, they're already making timid kisses on each other's lips. "Good," you say. "Really get into it. Make me think you enjoy it."
They look at you and comply. You're tempted to let them go for it, but you need to make a few things clear. You separate them again with your index finger. "When I say something to either of you, I want an answer. Is that clear?"
They both look downwards. "Y-yes," you hear the tall brunette, Kelly, saying.
She looks up at you, just as your middle finger and thumb come towards her in a circle. You consider flicking her hard, but she hasn't really earned a punishment yet. You flick the air above her, and both she and Cathy noticeably flinch. "You know my name," you say. "Try again, both of you."
They both understand. "Yes, Master," they both say, albeit quietly. That'll have to do for now. "All right then," you say, a bit more cheerfully. "Now kiss. And do it right this time."
They embrace each other and start making out again. After a few moments, you'd almost be fooled into believing it. They're acting like they want to be all over each other, with their hands all over each other's bodies and their tongues in each other's mouths. You're loving it. It's like a porn tailored exactly to your interests, right here in front of you. And if you want to change anything, all you have to do is make it happen.
