You see that she is just waiting for you, staring at you until you can do nothing else but agree and go inside.
You find that it is strangely like she is ordering you inside, commanding you. But it's odd that you feel that way, as she didn't say anything you remember as an order. Somehow she just took it as a given that you would do what she wanted.
You are embarrassed to find your cock stiffening painfully in your underwear. You wish you could find a moment to adjust it in private.
