Finish

Undeterred, your sister slips off her shorts and panties, and stands there in her birthday suit with her arms akimbo.

"What's the matter, a little embarrassed?" she mocks you, collects her stuff, and leaves the room.

After you clean up and find the courage to go downstairs, you find your sister in the living room reading a magazine, still nude.

"Oh, you can get dressed now..."

"I can? Good to know I have your permission, your majesty!"

You blush furiously as you sit on a chair near her place on the couch and turn the TV on.

The news turns on, and you try to focus but you really can't.

"Don't you feel cold?" You ask your bare sister.

"What's the matter, am I not embarrassed enough of a nude female for you? Do I undermine your assumptions about clothing and status?"

Stung by this, you sheepishly nod.

"I see; should I guess that your 'ENF' fetish is just your projection of your own bodily insecurities onto more attractive members of your preferred sex?"

You nod again.

"You really want me to get dressed again, don't you?"

You nod once more.

"Well, that's it. I might get dressed, but only after you get down on your knees and beg me, and promise that you'll never take nudity for granted again, or consider it embarrassing or degrading."

You do all of that, and your sister smirks. Time will tell what she'll do with this.
