A tank top and skirt, but no underwear.

You start in the nude, but decide against reaching for neither a bra nor panties. A gentle red comes to your face as you grow excited at what you're actually about to do. But you do continue, and you pull out a yellow tank top and slip it on. It must have been quite some time since you wore this particular garment. It fits incredibly tight on your body, really showing off every curve of your physique, especially your bust.

Next, you pull up a short pink skirt. It seems to hold more firmly than the one you wore the day before, which might be for the best. This is your first time trying something so naughty. You still don't want it to be too embarrassing.

Though, it does get to you. Through the tight shirt, you feel your nipples grow excited from the promise of the day. Could you really do this? It could be humiliating, but for some reason, it makes you tingle at the thought. You'll be commando, and everyone around you will have no idea...

You put on a pair of flats and step out of your bedroom. There, your sister greets you, eating cereal in the kitchen. She looks to you as if waiting for you to explain the night before. You tell her you don't want to talk about it.

"Aw. Come on! The story behind how you lost all of your clothes has to be amazing. Or did you just feel like streaking your way home? I wish I was there... It sounds like it was hilarious."

It might have brought you an embarrassing amount of arousal, but it certainly wasn't hilarious. As your sister continues to laugh, you grab a small snack, eat it quickly, and start to depart. Even the thought of explaining it all to your sister makes you shudder. You'd never hear the end of it. Though, that might happen anyway.
