Take her bra and 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. Although public nudity is still uncomfortable you realize she's been starting to get used to being entirely naked in your presence anyway, which would spoil the fun. You wax philosophically, how surreptitiously removing individual items serves as a reminder; you can get anywhere you want, run your hands all over her whereever you wish, and nothing can stop you. The first articles of clothing are a stepping stone, building the anticipation and excitement that at any moment there might be more clothes missing, until skin is exposed that shouldn't be..

You settle on going for all her underwear. 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, that her breasts aren't held quite right underneath her shirt, while her crotch grinds directly against the inside of her pants, or would you like to rub her nose in your omnipotence and show them off to her?
