Just scare her

Carmen is near tears as she pleas with you using her eyes, and you laugh, knowing that she's sufficiently scared and while she's willing to suffer your cock, it appears she can't stomach the thought of the janitor joining in.

"Absolute obedience?" you ask her. Carmen nods her head furiously, **** back her tears.

Without her noticing, you activate your mind control ring and turn to the janitor. "You can leave now. Forget you saw anything and don't tell anyone, ever. And close the door behind you," you say. The janitor nods his acknowledge and leaves, and by the time you deactivate your magic ring and turn back to Carmen, it looks like you've just been really assertive. Judging from her relief, she hasn't noticed that your instruction to the janitor had been received too easily.

Once the door closes, Carmen's body relaxes and you feel her thighs parting, although she keeps her hands over her pussy. You don't mind since she's also touching your cock. However, you have other plans now, and you pull out of her, letting your long, hard cock plop out of Carmen's pussy with much slickness. Carmen is breathing regularly again as she watches you stand, and she takes your hand when you offer it to her, helping her to her feet. Then, you pull her over to you as you spin around and sit down, taking her place on the couch. Holding the base of your cock and looking up at Carmen, you give it a few shakes.

"Absolute obedience," you repeat the 2 words from before, and Carmen gulps visibly as she starts to straddle you. No more words from you are needed as she adjusts her body onto you and grips your cock as she sinks onto it slowly until she's all the way down. As she starts to rise up, you put a hand on her waist and stop her. She looks at you curiously.

"Hold on. No rush. Let's talk first," you say with a grin.
