Take her panties

There's no need to strip her all the way naked again, sometimes a bit of minor teasing can be far more arousing than straight-up pornographic levels of nudity. You get the sense she's been starting to get used to being fully naked in your presence anyway, and it'd spoil the fun if she wasn't at least a little bit embarrassed. Going in small steps is different: You wax philosophically, how surreptitiously removing individual items serves as a reminder that you can get anywhere you want, run your hands all over her whereever you wish, and nothing can stop you. The first article of clothing is a stepping stone, building the anticipation and excitement that at any moment there might be more clothes missing, until some part of her body is exposed that shouldn't be..

You settle on going for the panties. But do you do it stealthily and leave her unaware, delaying the moment she realizes something's not quite right until some point in the future, as her crotch grinds directly against the inside of her pants, or would you like to rub her nose in your omnipotence and show it off to her?
