A slippery twist and a prize for the winner.

Finn took Candy's hand and eagerly tugged her along into the living room. "I'll show you in a second. You set up the mat and I'll go get something for the game." Without waiting for her response, he dashed down the hall and then upstairs, out of Candy's sight.

The blond babysitter didn't know what new rules Finn had in mind, but she thought that he seemed so excited to play that they must be something really fun. She set the open box on the couch and then unfolded the plastic rainbow-dotted sheet, giving it a shake before laying it out in the middle of the carpeted floor. There were still some deep creases in the plastic, so Candy knelt down on the floor and smoothed out the sheet as well as she could.

When Finn came back into the room, he was greeted by the rear view of Candy stretched out across the sheet as she smoothed it out, the perfect ass pushed out again as she spread her hands across the sheet. He paused a moment to admire the view and then quickly stepped over to the Twister mat. "Okay, Candy! Look out!"

"What?" Candy sat up just in time to see the boy aim a small plastic bottle at the sheet before a stream of clear liquid shot out. She watched him swing the bottle back and forth as he made sure to coat every inch of the mat in a shiny glaze. "Finn! What're you putting on the mat? Now it's all wet!" She reached out and ran her fingers across the plastic sheet, finding the sprayed liquid was thicker than water and quite slippery.

"This is one of the twists," Finn said proudly as he tossed the empty bottle to the side. "Normal Twister is kind of boring, so we put this slippery stuff on the mat and it's even harder to keep from falling down, like you're playing on a Slip and Slide!" He put his hand palm down on the sheet and smeared it around to show Candy how slick it was. He'd found the bottle of lubricant in his mother's bedroom dresser after the rest of the family had left and had pocketed it, but this Twister game was going to be a much better use for it than the jerk session he had originally planned for it. "Now, it's all slick and slippery, plus, when you fall down, there's a fun wet SPLAT!"

The busty blond ran her hand across the slippery sheet as well, but nibbled on her lip hesitantly as she looked to Finn. "This isn't going to stain the carpet, is it? I don't want to leave any stains that we can't clean up..."

""Nah, it'll be fine! We play like this all the time and it hasn't left any spots yet!" The boy had no idea if it would leave a mark or not, but he couldn't care less if it did, at the moment. "But we do normally wear clothes we don't mind getting dirty. I'm fine in what I'm wearing," he said as he touched his baggy shirt and left a wet fingerprint. "Do you have some old clothes you can wear for the game?"

Candy looked down to her cute shirt and shorts and then shook her head. "I didn't bring anything like that along, and I don't want to ruin these clothes. Maybe I could run home quick and get some. I only live a few blocks--"

Finn grabbed her hand in his slippery fingers and shook his head emphatically. "No! Don't go! You don't have to do that!" He didn't want to risk the ditzy blond telling her parents that she was about to play Slippery Twister, and he had a much better idea. "You can just take 'em off! I mean, playing in your underwear is just like wearing a swimsuit and you said you swim with the twins all the time, right?"

Candy could tell that Finn seemed really worried about being left home alone again and realized that he was right. She was needing a new bra anyways and if this one got a little dirty, it was no big loss. "Okay, you win. I won't run home," she said as she gave the boy a teasing smile and then grabbed the bottom of her shirt and pulled it up over her head.

Finn's eyes grew wide as saucers as he watched the gorgeous blond pull her shirt off, revealing a white lacy bra that was obviously too small for her based on the way her huge tits were swelling out the top of it. The twin creamy mounds of titflesh jiggled in her bra as she struggled to pull her arms out and Finn felt his cock go completely rigid in his shorts. Still staring, he watched as Candy tossed her shirt to a nearby chair and then she stood to remove her tiny shorts.

"So, was there anything else," Candy asked as she began unbuttoning her shorts, "You know, to make the game more interesting?"

Finn was almost speechless as she began wiggling her hips to slip out of her shorts, the motion making her succulent perky tits wobble even more. He finally managed to stammer out, "Y-yeah. There's a prize, for the winner. The winner gets a favor. They can ask for it whenever they want and you're not allowed to say no."

The blond slid her shorts down her long legs, revealing a pair of pink panties with a cute cartoon kitty on the front of them as she asked, "You can't say no? Does that mean no complaining, either? So, if I win, and and I tell you that bedtime is 7 p.m., you have to go to bed and you can't argue about it?" 'That just gives me and Andy more alone time later,' Candy thought to herself with a sneaky smile.

Finn tried to not be too obvious as he stole glances at her pink panties and wondered about what was hidden underneath. "Yeah, that's right, but you can only use it once, and it can be any time for the rest of the weekend." He couldn't help but gawk as she bent over to pick up her shorts, her tits nearly spilling out of her bra as she did, and then she tossed her shorts over with her discarded shirt. "Does that sound fair to you?"

"Sure! I'm not afraid of a little bet, especially since I'm going to win," Candy said in a joking tease and stuck her tongue out at Finn. "Let's play!"
