Part 2
Nicole felt Rachel quickly untie her from the chair. In moments, she was free of her bonds, save for her gag and the hood. Rachel made no move to remove the hood. She didn't want Nicole to see what she had prepared…yet.
"March!" Rachel ordered, leading her captive a short ways to one of the small, downstairs bathrooms. "You won't have a chance later, so whatever business you've got, take care of it now." Rachel told Nicole, opening the door.
Nicole pulled the sack-hood off while she paid call to nature. She made sure to put it back on before opening the door and stepping back out. Nicole was as eager as Rachel was for this game, whatever she'd come up with, and Nicole didn't want to end up spoiling the surprise by seeing what her friend had prepared to early.  
All other business concluded, Rachel took Nicole back to the kitchen and pulled the hood off of her friends head. Right away, Nicole's eyes were drawn to the kitchen table, or rather, what Rachel had laid out on the table.  
She gasped. Laid out on the table was a variety of bondage devices. Nicole saw two pairs of leather handcuffs connected by a long chain; between them, what looked like a rubber ball gag, and a high leather collar. Where had Rachel gotten all of this?     
While Nicole was looking over the table, Rachel came behind her and untied the scarf cleave gagging her. She handed Nicole a glass of water. Nicole gulped the water down. Her mouth was dry after being gagged. Rachel took the glass from Nicole and put it on the table, out of the way. She picked up the ball gag.
"Where on earth did you get that!?!" Nicole exclaimed.
"Oh, it's my older sister's. She's got all sorts of neat stuff lying around if you know where to look." Rachel winked mischievously. "I just 'borrowed' them for our little game today. Good thing she's not here right now. What she doesn't know won't hurt her…"
Rachel must have seen the look on Nicole's face, because she quickly added, "Don't worry. I washed off the gag first. Now open up…" She stepped around behind Nicole and held the gag up, ready to use.
Nicole opened her mouth and let Rachel gag her. Instantly, the taste of rubber filled Nicole's mouth. Rachel slipped the ball between Nicole's teeth, and tightened the straps behind Nicole's head. She locked it on with a small padlock.
The ball gag was different from the various cloth or tape gags Nicole had experienced during her games with Rachel and her own self-bondage forays. Unlike a cloth-gag, it didn't immediately suck all the moisture from her mouth, if anything, quite the opposite as the ball quickly became wet as Nicole tried to breath around it, and drool began to form around the corners of her mouth.
Meanwhile, Rachel picked up the first pair of leather cuffs, slipping them around Nicole's wrists in front of her and locking them on with two more small padlocks. Nicole tested the chain out; the short chain made it difficult, but she could still use her hands.
The second pair of cuffs went around Nicole's bare ankles. Again, they were secured with small padlocks. Nicole shuffled around a little. The chain prevented her from raising her hands above chest height, while the cuffs on her feet meant she could only take short steps.
The last item was a high leather collar that went around Nicole's neck. Nicole felt a tingle as the collar was buckled snugly around her throat, not tight enough to be uncomfortable, but enough that she wouldn't forget it was there. A last padlock went through the ring on the front, locking it around her throat.
"Now allow me to explain the rules of the game…" Rachel said, "As you can see, all of your bonds are locked with a padlock. Each one has a different key. Six padlocks, six keys. Simple enough?"
Rachel held up a stopwatch. "These keys are hidden around the house. You'll have, oh, the next three hours to find them. You do, I'm yours for the rest of the evening, whatever you want to do with, or too, me, goes."
Nicole brightened up at the thought of having her friend at her mercy. Almost immediately, she began plotting what to do to Rachel.
"But," Rachel said, interrupting Nicole's happy plotting, "You need to find all six, and unlock all of the locks before the timer runs out. If you've even got one left on when you run out of time, then you're my slave for the evening and you get to do all my chores." She grinned evilly.
Nicole rolled her eyes. Rachel fondly imagined herself as some sort of slave, crushed under the unfair burden of chores her parent's reveled in pilling on her.
In some of their previous games, Nicole had already ended up owned by Rachel a couple times, having to do her chores. The submissive she was, Nicole found the prospect of bondage-housework to be more exciting then dreadful.
"Well, any last questions before we begin?" Rachel asked.
"Mmmppphhh!"
"Oh…right. Guess not." Rachel said with a chuckle. "Then the game starts…Now!"
For a couple seconds, Nicole shuffled around the room, uncertain of how to proceed. The keys were hidden around the house, but where? That was a lot of ground to cover, and she doubted Rachel would make things easy for her by leaving them in easy to find places.
Rachel interrupted her thoughts. "Hey, wake up Nicole! Clock's ticking!"
Without anywhere better to start, Nicole began looking around the kitchen. She opened up a couple cabinets and knelt to look around amongst the cans and boxes filling them.
"Oh, word of advice," Rachel said offhandedly, "I didn't hide any of the keys here. That'd be too easy."
"She might be lying," Nicole thought to herself, skeptically. Rachel had no reason to help her, and plenty of reasons to want to keep Nicole from finding a key, if there was one hidden here.
Then again, Rachel might have known telling Nicole there wasn't a key in the kitchen would be the easiest way to convince her there was one there, and make her waste her time searching for a key that wasn't there.
Nicole shrugged and struggled to her chained feet. No use wasting time arguing herslef over it. She could always come back later, and even if there was one key here, there were at least five keys she knew where hidden somewhere else. Best things to do would be to move on.
As she hobbled to the door, Nicole quickly realized Rachel's plan, such as it was. With her feet locked in the leather cuffs, her movement was slowed to a crawl. At this rate, she could spend half her time just walking from one side of the house to the other.
"And where do you want to be the keys to those cuffs are hidden?" Nicole thought to herself. Still, nothing to do but play the game as best she could and hope for the best.
The next room over from the kitchen was the living room. Nicole slowly hobbled her way to the center of the room. Rachel followed, giggling at Nicole's struggles. There, Nicole got her first break. Almost immediately, she noticed one of the cushions on the couch had been disturbed and not set back right.
Sure enough, when Nicole moved the cushion, a small silver key glinted in the light. Nicole picked it up and held it up triumphantly for Rachel to see.
"That was an easy one, so you won't feel too bad when you lose." Rachel said. "You'll never find the others on your own."
Nicole ignored her, busily trying the key out on different padlocks, searching for the one it went with. Not the cuffs on her ankles, Nicole wasn't surprised. There was no way Rachel would give up her best advantage this early in the game. Not her arms either.
Nicole reached around awkwardly to try the padlock on her gag; she had to bend over to get the padlock within range of her chained hands. To her surprise, the key slipped in easily and turned. With some relief, Nicole unbuckled the gag and slipped it off, wiping away the drool that had begun to form around the corners of her mouth. She worked her jaw; they'd gone sore from the large gag.
"That's one." Nicole said, handing the gag, lock and key to Rachel.
"Very good, just five more to go" Rachel said. "I'll hang on to this. You'll be wearing it again soon enough when you're my slave for the evening." She grinned. "The games just begun…"
