A French Maid Outfit

You reach into the bag and pull out a French Maid Outfit.

"You've got to be kidding?" You say, outraged. "You really expect me to wear this?"
"If you want release, yes." Natalie replies, matter-of-factly. You dig a little deeper in the bag and pull out a pair of white stockings and a pair of black high-heeled pumps.
"All of it?" You ask.
"Everything that's in the bag." Replies Sara.
"This is the cruellest thing you've ever done. Is this really necessary?" You ask, a note of pleading in your voice.
"Probably not, but it's fun for us." Replies Jiun. You can see that when you put on the outfit, your caged dick would poke out under the skirt, for all to see. You can't believe you're actually entertaining this as an idea. The girls have always been flirty with you, and teased you, but they've never made you do something this outright humiliating. I suppose technically they're not making you do it.
As if you needed a reminder of what was at stake, right then, your phone buzzed. It was a notification from Tinder. You start to think of all the ways you could enjoy yourself this weekend, free from your chastity cage. Without a word, you drop the outfit back into the bag, and quickly shuffle off to your room.
"Oh My God. He's actually doing it." Joy cackles. "He's actually going to wear it. He must be so **** and horny." You are, but you can't let an insult like that stand. These girls might control your dick, but they don't control your life. You give each one the finger, flipping them off in turn, before sidling into your room.

It takes a while to put on the outfit. It's very tight, probably a few sizes too small. You would never admit this to the girls, but you kind of like the way the material feels on your skin, it's soft and smooth. You emerge from your room, your pumps clacking on the hardwood floor. The girls see you and stifle a giggle, but don't comment.
"Just in time, the first guests are about to arrive." Jiun says.
You catch a glimpse of yourself in the reflection of the sliding glass door, and wonder, not for the first time, how did it come to this? How did you wind up here? Honestly, at any point, you probably could have overpowered the girls and taken your key back and unlocked yourself, but the truth is, you didn't want to. Deep down, you like the power they have over you. You like it.
You like it, and you can never admit it.
