A Whole Nude World

The main character wakes up the morning after a wild party. They are in their bed trying to clear away the haze when they realize they are butt naked. Not only that, but they look over at their roommate and realize, they are also completely naked. The main character scrambles to the closet for some clothes, but all the clothes are gone. They look into the hallway and there are naked people everywhere. What is going on?

The main character is the only one who has any knowledge of a world in which clothing exists. Everyone else only knows a world of free bodies and free sex.

Alternate reality where clothes don't exist and have never been invented. There are cloth materials, but those are mainly towels and bedsheets. No one needs to remove clothes because they don't wear any. It's not shameful to be naked, and no one thinks it's weird except the main character. Casual sex is commonplace and everywhere you look people are fingering, giving hand jobs, sucking, and fucking. Orgies and group sex is also normal. Some couples are monogamous, but they are the rare ones.

Have fun!
