You sound convincing enough. Take off your panties.
Keep your thighs pressed together while you take them off, I don't want your clitty springing free just yet.
Once you have your panties off, get down on your knees again.
If your clitty bounded out before now, take a ruler and slap it until it is as soft as it gets.
If you've maintained control, you can spread your legs for me when I show you my breasts.
