The Girls Toy With You

After a few hours sleep, you wake up and perform your morning duties. Pretty soon, the girls emerge from their rooms for breakfast. Sara's eyes are slightly bloodshot, she definitely drank the most last night, and it shows. Jiun looks perfect somehow, with not a hair out of place. The girls are silent all through breakfast, which is unusual, but you don't remark on it, just enjoying your breakfast in your pyjamas, finally free of that wretched maid's outfit.

After breakfast is over and you've done the washing up, the girls call you into the living room. Oddly, they are all standing in a line behind an overturned desk. From left to right: Joy, Jiun, Natalie and Sara.
"What's going on here?" You ask hesitantly.
"Well, we had a little conference and we all agreed that you did a good job last night." Joy said. "Many of our guests remarked on how courteous and obedient you were, a few of them even said they wanted cock-locked servants of their own. So, with all that in mind, we decided that you've earned a release."
Your heart soars. Yes. Finally. After two months of agony, you've done it, you've finally pleased these girls enough to earn a weekend of freedom. Your eyes flick instinctively to the key around Natalie's neck, and you do a double-take, it's not there.
"Ha, he's finally noticed." Jiun giggles.
"Took you long enough," Natalie teases, looking at you. "That's right. I'm not wearing the key around my neck anymore, but don't worry, one of us still has it. You see, we said you've earned a release, but if you think back, we never actually promised you could have one. If you want a release, you'll have to win it." You groan loudly, sick of these beautiful women and their twisted games.
"Oh don't be like that." Sara snaps. "It's very simple. One of us is wearing the key on a chain around our ankle. All you have to do is correctly guess which of us is wearing it, and which leg we're wearing it on. If you guess correctly, we'll unlock you for 48 hours. If you guess wrong, well...I suppose you can try again in a couple of months."
All the girls giggled at that one. You didn't find it funny though. The upturned desk blocked your view of the girls legs', you couldn't see anything below their waists. "So, you've got 30 seconds to guess. Starting...now." Said Natalie.
Your brain went into warp-speed. You weren't going to let these girls deny you the release you'd degraded yourself to earn. As it stood, the odds of you guessing correctly was one-in-eight, 12.5%, not exactly favourable. There had to be some way to narrow the odds. An idea popped into your head, suddenly, a risky idea, but it just might work. Without warning, you stomp down hard on the hardwood floors. The vibrations travel through the floor and you hear a faint tinkling sound from...your left. You can't be sure, but Natalie is counting down. "...7,6,5,4..."
"Jiun." You say quickly. "Jiun is wearing the key on her right ankle."
Natalie stops counting. The girls all look at each other with sly looks on their faces. Slowly they step out from behind the desk. Your heart is racing, but everything else seems to be going in slow-motion. You slowly move your eyes down to look, terrified that you've gotten it wrong. You can't spend another two months in chastity. You just can't. You need release.

Jiun emerges from behind the desk. A chain around her right ankle.

YESSSSS, you've done it. You guessed correctly.
"Well, that was a clever move." Joy said. "I guess we can't fault you. You used your brain."
"You earned a release, and you won our little game." Jiun said. "Come here." You stepped forward as Jiun removed the key from her ankle and inserted it into the lock on your chastity cage." She paused for a second, then said. "Seriously, 48 hours, not a second more. We'll be setting a timer. Your time starts the moment I turn this key. Ready?" You nod. Without any further ado, she abruptly turns the key and slips off your chastity cage. You rush off towards your bedroom, but Natalie has one final warning. "Remember, we still expect you to do all your chores. This release is a privilege, and if your domestic performance suffers, we might have second thoughts about giving you another one."
"I understand." You say, quickly, hurrying out of the room, **** to enjoy every second of your freedom.
