Jeannette walked down the stairs to Simon's lab in the basement, the now familiar feeling of the belt sealed around her waist though she lacked the plugs today. The day before Simon had gone down and begun to work on an experiment, the details of which he hadn't shared with either of his brothers 'though I have a pretty good idea.' Jeanette thought to herself.

Before last Friday whenever she and Simon had been intimate, they had made sure to not to risk her getting pregnant. That night's series of events, however, had left them both so clouded with lust that neither of them had thought to take such a precaution until the day after.

After a thorough cleaning, more for a psychological benefit than a physical one, and several tests, Jeanette was reasonably confident that she was not going to end up pregnant. 'Yet anyway' she thought with a smile. Still, she couldn't deny how amazing the feeling had been and it seemed Simon had agreed.

As she opened the door to his lab, Jeannette saw Simon sealing a bottle of a sweet-smelling opaque orange liquid. "What's that Simon?" She asked.

Jumping slightly at the unexpected noise, Simon turned to Jeannette. "Hey Jeanette, I didn't see you there." He said when he noticed her. "I'm just working on an experiment, if it works it will provide a superior method of contraception with no major long-term side effects." He explained, slightly shaking the container.

"Really?" Jeanette questioned. "There's no way even you developed something like that in a week." She doubted.

"No, but I didn't have to. It is based on an old formula created by a could of doctors in the seventies." Simon conceded. "It's called the Plote-DeVise formula. It works by essentially turning the entirety of the seminal tract in males and fallopian tubes in females toxic to both sperm and egg cells." He explained turning back to look at the cages of lab mice on the wall. "It was dropped because the amount of chemical needed to coat the linings in most creatures, including humans, is enough to poison them. However, chipmunks metabolize the chemical quickly enough that it poses little risk to them in doses effective enough work for its contraceptive effects." Simon continued. Turning back to Jeanette he began to walk towards the stairs saying. "This is the latest version of the formula, it needs to chill before it can be used but the side effects should be at least halved."

"Side effects?" Jeanette said as she followed him up the stairs. "What kind of side effects?"

"Increased hormone and pheromone production. The metabolizing process of the toxin releases them at an increased rate, effectively increasing libido and arousal." Simon answered as he turned towards the kitchen. "That's why I had the mice in separate cages, otherwise they just don't stop." Reaching the fridge, Simon put the container on the bottom shelf, next to a gallon of milk and an over half-empty bottle of orange juice. "I hope Theodore and Eleanor get back home before the storm hits," Simon said absentmindedly. "They went grocery shopping for this weekend, right?" He asked turning back to Jeanette.

"I think so," Jeanette replied. Looking down a coy smile appeared on her face. "One last question about the formula Simon, Is it airborne or is that just from me?"

Simon, having seen her eyes and smile, grinned. "Little of column A, little of Column B. Either way you're going to take care of it now aren't you?" He asked while unzipping his pants. "After all, Alvin and Brittany are at your house right now."

"Well it that case…" Jeanette said as she dropped to her knees in front of him. "I better get to work."

Running her tongue from the base of Simon's cock to the tip, Jeanette wrapped her lips around his head. Grabbing the top of her head, Simon began to unconsciously rub his hand through her hair. "Good girl Jeanette… ohhh, I haven't had any relief all day. You're going to fix that for me huh?" Simon moaned as Jeanette swirled her tongue around his head.

As Simon was lost in the pleasures of Jeanette's tongue a crack of thunder seemed to almost shake the house. "Wow, they really better get home soon or else they will be in a downpour," Simon said. Jeanette however, was occupied and couldn't respond.

Brittany moaned as her fingers danced along her clit, teasing herself slowly towards an orgasm. But she wasn't just trying to cum this time, she was putting on a show. Alvin stood at the foot of her bed, recording her with his phone. Brittany knew that he would probably use it on lonely nights but she had the suspicion Alvin wanted it for more abstract reasons. He simply wanted videos of her doing he said because just having those videos made him feel strong. And Brittany was too happy to oblige.

"Alvinnnn…" She moaned writhing on the bed, edging closer and closer and closer. "Alvin this feels so good." Brittany was lost in a fog of pleasure and failed to notice Alvin walking closer and closer to her until he was right above her legs.

It would be an awkward place to give her oral, but Alvin had a different idea anyway. Leaning over he held his breath, as Brittany's own quickened. Finally, her ministrations exposed her clit fully to the air and in that exact moment, Alvin blew a quick breath on it, as though he was blowing out a candle.

Brittany's body, already on the brink and hypersensitive, exploded in pleasure. "Alvinnnnnnnn!" She screamed in orgasmic bliss, her whole-body convulsing. At the same moment, a crack of thunder shook the windows and caused Alvin to jump in surprise.

"Damn, I knew I was good but I didn't realize I was that good!" He said after a moment.

"Oh… shut up, Alvin… I did most of the work." Britany retorted out of breath. A few drops of rain fell on her from her open window.

"Maybe, but I bet it wouldn't have been so thunderous without my help," Alvin said in response. "Anyway, as much fun as I've had here, I'm going to go back to my house and clean up my room. You can pay me back tonight when you're there with me."

After groaning at Alvin's pun Brittany waved a hand at Alvin and asked, "Can you shut my window before you go?"

After doing as she asked, Alvin quickly walked around the girl's house making sure all the doors and windows were shut. The storm they were going to get that night was supposed to be pretty bad and last all weekend so the girls were staying over at their house, Simon had rigged several backup power sources and a couple of downloaded movies meant they would have a fun little sleep in.

After spending several minutes securing their house, Alvin left and ran home. The rain was already coming down hard. Rushing inside Alvin quickly removed his shoes and walked to the kitchen to make himself something to eat.

Checking the fridge he saw the nearly empty bottle of orange juice, drinking the entire bottle he felt momentarily guilty before noticing the second bottle. 'Ah, that must be a new bottle' He thought, throwing the old bottle of orange juice in the garbage. 'I wonder if Theodore will get an extra on accident then?' He wondered Idly as he walked upstairs to his room.

Eleanor let out an involuntary moan as one of Theodore's fingers curled inside her hitting her G-Spot. Luckily a loud rumble of thunder echoed nearly at the same time so the only person who heard her was Theodore himself.

"Quiet now Ellie," He whispered in her ear, "Or do you want them to catch us?" He said, uncurling his finger. Catching herself this time, Eleanor squirmed in Theodore's touch. Ever since last Friday he had been so much more physical with her. He barely kept his hands off her when they were alone, and even in public, he could be brazen.

As he was proving now. They were at the store buying some last minute groceries for the weekend before the hit, they had grabbed most of their list but as Eleanor was looking for one of their last items Theodore had slipped his hand between her legs, teasing her. Hidden on one side by a stocking cart and on the other by a wall they were fairly well hidden, but far from unreachable.

"We… ah… we should probably get going Theo." Eleanor managed to stumble out as Theodore fingered her. "We can finish this t-tonight if w-we wait too much longer… ohhhh… we might get caught in the worst of the storm, and we still haven't gotten orange juice or... Ohhh!" She yelped as Theodore found a particularly sensitive spot.

"You're right Eleanor," Theodore said reluctantly withdrawing his hand from between her legs. "Wouldn't want you getting wet, would we?" He asked wistfully.

Hearing the serious tone in his voice Eleanor couldn't suppress a giggle. "It's a bit late for that Theodore, thanks to you." Theodore looked at her confused for a moment before he realized what she meant as a blush spread over his face. 'He's so cute when he does that' Eleanor thought lovingly. 'He hasn't changed at all since last week, I almost thought he might. I feel like I have.' Struck by a sudden thought Eleanor grinned. Turning her head to make sure there was no one else nearby Eleanor spoke up. "But you know, there's no point in wearing wet clothes," She said seductively.

Theodore's jaw dropped as Eleanor Squatted and removed her panties. Walking pass Theodore she hid them in the pocket of his hoody. On an Impulse she winked at him and began to walk towards the registers with their groceries, her hips swaying just enough to show her now lacking attire.

Eleanor saw Theodore walk out of the store as she was paying. Walking out her yelp was cut off as she turned the corner and Theodore kissed her. Holding her for nearly a minute his hands wandered to her now bare rear and Eleanor shivered as the cool wind from the storm blew on her bare skin.

Finally breaking off the kiss, Theodore growled in her ear, "You are going to pay for that tonight."

"I can't wait," Eleanor whispered back.

Later that night, all six chipmunks were sitting in the Seville living room about to watch a movie. The power had gone out on the street a few minutes earlier but Simon's backup power supplied them with just enough energy to keep the lights on and keep appliances working. Everything was fine until the computer fried.

"What do you mean you lost it?" Brittany demanded hands placed on her hips standing right behind Simon. "You said you downloaded the movies this morning?"

"I did, and I put them on this flash drive," Simon replied still fiddling with the computer near the TV. "But apparently the one time I don't safely eject it, it lost all the data. And the internet is out so I can't even redownload the movie. "

"See Si, this is why you just take it out every time. Then it gets used to it and doesn't break when you need it." Alvin spoke as though he was offering wise advice.

"That is definitely not how it works Alvin," Jeanette responded from the couch. Shifting slightly to get in a more comfortable position with the belt hidden around her waist.

"Can you fix it, Simon?" Theodore asked, his attention split between the conversation going on in the living room, and Eleanor making them fruit smoothies in the kitchen. Her lack of underwear was apparent through the tight pajama pants she was wearing.

"If I could access the internet and reset it from the backup in the cloud sure. But with the storm, the cable is out and so is our internet." Simon replied standing up.

"Well that's great, what do we do now?" Brittany asked.

"Play a board game?" Suggested Jeanette

"I don't think we have all the pieces to any of our board games," Theodore said as Eleanor entered the room.

"Here's your smoothies everyone," she said carrying a cookie sheet as a makeshift platter with six large glasses of a yellow-orange liquid. You guys didn't have enough oranges, so I cheated a little and used orange juice." She explained as she passed them out.

"I'm sure its great Eleanor, when's the last time you made something bad?" Simon asked as he took a glass.

Taking a deep drink, Alvin burped and grinned. "Taste fine to me." He said after he was finished, earning a disapproving glance from Brittany.

As everyone took a glass and began to drink, the conversation once again turned to entertainment for the night.

"So no movie, no cable, no board games, is there anything we can do for fun tonight?" Brittany asked as she looked around as though hoping entertainment would appear from the air. She wiggled slightly on the floor, a slight heat building in her core. 'Am I imagining it or is it starting to smell really good in here?' she wondered sipping from her glass of Eleanor's smoothie.

"What, do I not count?" Alvin asked with mock indignation. Taking another drink from his glass as he did so. "These are seriously good Eleanor." He said as he finished the glass.

Slightly startled by Alvin's compliment Eleanor began to thank him when she was interrupted by Brittany. "Well Alvin, I was thinking of something all of us could do. Plus it would help if it was something that takes longer than two minutes." She retorted. Causing Jeanette to choke on her drink as she started to laugh.

Raising one eyebrow up Alvin looked at Brittany before glancing at Simon, who was helping Jeanette to clean up, and then back at Brittany 'Do you really want to play this game Brit?' He wondered.

Brittany saw his looked and interpreted it correctly, her cheeks reddening before she looked down. 'Well that was strange' Eleanor thought as she noticed the exchange. Shifting slightly to find a position that wasn't so awkward, she was far more turned on by not wearing any panties in front of everyone than she thought she would be. Picking up her now nearly empty glass the drank the rest of the smoothie and began to refill it.

"Anyway…" Simon said after Jeanette had finished her coughing fit. "We will just have to hope the internet comes back on and find something to d… and activity to do until then." Shifting his pants slightly to hide his growing erection, 'Jeanette smelled so good…' he thought.

"Well that doesn't leave many options," Jeanette said from next to him wriggling her hips slightly. Something about having Simon on top of her with everyone else in the room was making her squirm, the unforgiving belt, however, did not offer any comfort. "How about a trivia game?" she offered.

"What, and let you and Simon have all the fun? Pass." Alvin answered quickly. He couldn't deny that something was turning him on but he had no clue what. "How about truth or dare instead? Here…" Picking up the TV remote Alvin spun it on the table until it stopped with the power button pointing directly at Eleanor. "You get to ask first Eleanor, unless someone else has an idea?"

Theodore, on his third glass of Eleanor's smoothie, grinned as he thought of a way to get back at her for the grocery store earlier. "I think that sounds like fun Alvin." He said as he walked towards the table.

"Uhh, okay," Eleanor said, looking she decided to satisfy her curiosity from last week. "Simon, Truth or dare?" she asked.

"Truth" Simon replied,

"What was the present you brought over to our house for Jeanette last Friday? Eleanor asked.

Simon and Jeanette's faces both went red almost immediately. Simon reached for his barely touched glass and took a drink to buy himself time to answer, 'Why did that have to be the first question?' He thought. Thinking quickly, he almost had a satisfactory answer when he heard Jeanette answer next to him.

"He built me a… he built me a chastity belt." Jeanette said her face flushed red, though whether that was embarrassment or arousal she couldn't tell. Setting her now empty drink glass down she tried to sit up straight as she poured herself another, feeling a familiar wetness begin to form between her legs.

Alvin raised an eyebrow at the statement, he had figured Jeanette probably liked something crazy just like everyone, but he hadn't suspected that or that Simon would be into it.

Brittany's eyes blinked back and forth between Jeanette and Simon. A part of her idly wondered if Jeanette was wearing the belt right now and if Simon could build a second one. She felt a heat between her legs as she tried to cross them. Sipping from her now second glass of smoothie to cover it up, but that almost seemed to make it worse.

Theodore's eyes went wide as he heard Jeanette answer the question, he couldn't help but think what it would be like to have control over when Jeanette could cum or even just touch herself. Theodore began to wonder what it would be like to sleep with Jeanette.

Eleanor, to her credit, was embarrassed about asking her question. She had thought it had been something cheesy or corny, not something so private. "Uhh, sorry Simon." She said lamely as an apology.

"It's not your fault, you didn't know," Simon said after a moment's hesitation. Deciding just to play along with the game he turned to Brittany and asked, "Truth or dare?"

"After that kind of a question started us off, I don't know which is safer." Brittany joked. "truth," she said after wiggling for a moment.

Simon wracked his brain trying to figure out an appropriate challenge for Brittany to perform, each one raunchier than the last. Suddenly Brittany's glass fell over soaking her pants. She quickly took them off, not noticing the small stain appearing between her legs. Unbidden, images from last Friday popped in his head and he found he had his question. "How would you describe Alvin in bed?"

Brittany looked at Simon surprised, she hadn't expected him to escalate the questions. Still, she was bound to answer it and it's not like she could say anything bad. "Well for one what I said earlier was completely lie, he can actually last for two and a half minutes." She began eliciting a laugh. "But seriously, he's amazing he has a kind of natural confidence that makes you want to do what he asks you to and… its really almost indescribable." She finished lamely

Sitting down on the floor cross-legged, Brittany looked around noticing Eleanor's eyes were staring at Alvin in curiosity. Finally, her eyes settled on Jeanette. Unable to contain her curiosity she asked "Jeanette, truth or dare?"

Jeanette could see the gleam in Brittany's eyes and knew what her dare or question would be. Still, the idea made her squirm. After giving Simon a side-eyed look, she answered, "Dare I guess".

Brittany's face broke out in a broad grin as she gave Jeanette her dare. "Show us all every feature of your chastity belt on the belt itself."

"Hold on second." Simon interrupted, setting down his barely touched drink "That's a very personal thing to ask her to do and I get that we're trying to have fun but…"

"It's okay Simon," Jeanette said cutting Simon off. "I… I want to show them." Simon looked back at her and saw that not all, and possibly not most of the blood in her face was from embarrassment.

"If you're sure Jeanette." He said reluctantly sitting back dawn and sipping his drink.

Jeanette drank down her entire second glass before she finally wriggled out of her pants to show off her belt. Her audience watched in faces ranging from curiosity in Brittany to clearly visible arousal in Theodore. Sitting back down, Jeanette saw how much attention Theodore was paying to her and quickly asked him "Truth or dare Theo?"

Deciding to get it done with quickly because he had a plan, Theodore finished his fourth glass of smoothie before answering "Truth."

"Uhhh, when was the first time you had sex with Ellie?" Jeanette asked, a cloud of lust beginning to cloud her thoughts.

Simon looked at Jeanette in amazement, that wasn't the kind of question he had expected from her at all. 'What is going on with her, is she really getting that aroused just from showing off her belt?' he wondered.

Theodore had expected to answer right away, but even in his lust filled state he knew that this question didn't just affect him. Glancing sideways at Eleanor she gave him a little nod. Taking that as approval, Theodore answered: "Last Friday, I was too nervous to try anything before that." He said simply. "Eleanor, truth or dare?" He asked quickly turning to his girlfriend who was just finishing her own third glass of smoothie.

Taken a bit by surprise, Eleanor's eyes narrowed she mentally weighed likely questions against the likely dares before finally answering "Dare."

Grinning broadly, Theodore stepped backward and slightly off to the side so that he was facing everyone. Looking back up at Eleanor he said: "It doesn't seem fair that both your sisters are out of their pants so I dare you, to walk up to me and take your pants off and then grab your ankles for ten seconds." He ordered, letting a bit of the controlling voice he sometimes used during sex slip out.

This dare caused everyone in the room to gasp if Jeanette's question was startling Theodore's was a complete surprise. Eleanor began to blush furiously as she walked up to Theodore. Finally, with agonizing slowness she began to slide her tight leggings down her legs, exposing her shapely rear to the four munks behind her. When she had gotten home, she had taken a quick shower but decided to leave the underwear off as a way of teasing Theodore. She wasn't quite sure if she regretted that now or not.

When her pants were all the way off, she bent over and grabbed her ankles giving everyone behind her a completely unobstructed view of her now glistening slit. After seeing this, The perfect idea popped into Alvin's scheming mind. Reaching a count of ten at last she turned to go sit back on the couch. When she did so she felt Theodore kiss her cheek before sitting down next to her.

"Well, that was a pleasant view," Alvin said, breaking the silence. "And I think I'm the only one who hasn't been asked yet."

"Fine Alvin, truth or dare?" Eleanor asked hastily already having a plan to get back at Alvin for starting the game in the first place.

"Dare," Alvin said confidently.

"Strip all the way naked," Eleanor demanded smugly, thinking that Alvin would embarrass himself trying to weasel his way out of it.

Instead, Alvin just stood and shrugged his shoulders, asking, "Am I making this a show or do just want to see me naked?"

"Just strip Alvin," Eleanor said, desperate not to be the only one naked.

Sensing her discomfort Alvin chuckled and slowly began to strip, over exaggerating everything except taking off his underwear, which he did quickly. Afterward, he stood proud, even all five of the people in front of them stared at a fully erect cock.

Rotating his hips from side to side he finally got to ask his own question. "Theodore, assuming Eleanor was okay with it and so was Simon, would you sleep with Jeanette?" He asked, not bothering asking truth or dare.

"I…Uhh…. What kind of question is that? Theodore asked in shock.

"A serious one, would you?" Alvin insisted.

"I.. well… yeah, I guess. But ONLY if Simon and Eleanor were both aware and okay with it." Theodore stressed, looking between his brother and his girlfriend uncertainly.

"Thanks, Theodore, for the record, I would too," Jeanette said. With a sheepish grin, mirroring Theodore's uncertain look as she glanced at Simon and Eleanor.

Hearing this, Alvin's face broke out in a triumphant grin. "So it's settled then, we are all trading partners tonight?"

AN: Well that was fun to write as always feedback is appreciated.
