Nemesis Chapter 3

Still tired and hungover, following her late-night antics playing 'Ring of Fire' the evening before, Mia vowed to spend her entire Saturday afternoon recuperating, by watching TV, curled up on the sofa. Returning home from Lavender's, Mia threw on a white tank top and a short, navy, pleated skirt. They didn't really go together, but she wasn't out to impress anyone, so she didn't really care. The eighteen-year-old was half tempted to loll on the couch in just her underwear, but she half expected to fall asleep and was worried that her sister Rosie might invite her new boyfriend, Mike, home. Her fears were unfounded however as her older sister soon returned home from work, all alone, at seven in the early evening.

Standing at five-foot-six, the twenty-year-old Rosie boasted shimmering, shoulder length, light blonde hair. Still beaming following the previous evening's incredibly successful first date, Rosie made straight for the living room to pour her heart out to Mia. But, finding her younger sister asleep and snoring on the couch, the nurse tiptoed into the kitchen and filled up four buckets of cold water. Hiding three of them behind the back of the sofa, the blonde promptly emptied the fourth over her beguiling younger sister's head as a joke. Screaming, Mia, in shock at the sudden deluge, almost fell off the couch.

"Rosie!" the brunette groggily screeched, as water dripped down her fringe and slithered inside her sheer white top. Laughing, Rosie remarked, "After last night, I didn't want to be the only one to miss out. I can't believe that you let them gunge you. I'm gutted I wasn't there, I really am." Smiling, Mia pouted before blowing a raspberry. In retaliation, Rosie emptied the second bucket all over the teenager's front. Shrieking, Mia felt the water disappear down over her breasts, which were now highly visible beneath her evidently translucent white tank top. Catching sight of her sister's erect nipples, Rosie continued, "Naked too! Lavender proudly boasted about how they surprised you in the shower. Mia, you've always been so shy and reserved, I never thought you had it in you, but I like it!"

Delighted for her sister, Rosie lightly punched Mia in the arm. Continuing, the blonde added, "I really hope that this helps you turn over a new leaf and encourages you to go out more. I hate to see you sat at home, all alone, watching Tv on a Saturday night. You should be out there, having fun. But, please tell me, Lavender didn't take advantage of you, did she? She can be quite forceful and unforgiving some times." Shaking her head, Mia replied, "Oh no, I was happy to get involved, even though, I didn't know just exactly what Lavender had in store. But then again, there weren't any boys present, it was just four gorgeous girls having fun. Plus, I kind of deserved it, what with forgetting her birthday, didn't I?" "You sure did!" Rosie cackled, before upturning the third bucket over the bonny teen, as she tentatively sat back up.

Shrieking once more, Mia began to complain, before Rosie patted the empty bucket down over her forehead, shutting her instantly up. Ignoring her sister's muffled protestations, Rosie cautiously explained, "I'm not sure I could have been gunged like that. I'd have run a mile the first chance that I had. Lavender is my best friend, she's always been a bit of a tomboy, always been unafraid of getting messy, but even I didn't know, until recently, that she was into gunge. I hope its not a sexual thing, otherwise I'll have to have stern words with her, for tricking my sweet, darling sister into stripping off." Removing the bucket from her head, Mia was then surprised by her sister opening up the front of her tank top. Her hands slippery, the brunette was unable to fight back. Thus, Rosie easily emptied the final bucket over her sister's breasts as she sat helplessly on the couch, utterly soaked.

Shivering, Mia felt the water seep down inside her knickers before dripping down onto the cushions, where she sat. "Mum's not going to be pleased", Mia fretted, as the water continued to slather down over her breasts and backside. Sensing that her sister was drenched, Rosie suggested, "How about I bring you a fresh change of clothes? You're completely soaked." Bashful, Mia initially refused, but Rosie forcefully lifted her sister's tank top over her head, exposing her quivering breasts and flat, toned stomach. "Much better", Rosie joked.

Instinctively, holding the nearest cushion tightly in front of her chest, Mia felt the wet fabric rub uncomfortably against her skin. Conquering her nerves, Mia threw the cushion aside and stood back up. "Now who's trying to trick me into stripping off", the brunette joked, before pulling her sodden skirt down her legs. Wearing nothing but her white knickers, the stunning teenager giggled, as she handed her sister her clothes. "Since you're going upstairs, could you fetch me a nightie? Knickers too, these are soaked", she remarked. Pausing for a moment, to wait to see if Mia took off her panties, Rosie reached forward, only for her sister to slap her palm away. Embarrassed, the blonde suggested, "I'll also get you a towel, but, in the meantime, if you don't mind, could you start cleaning up?"

Submissively following her older sister's instructions, just like she had always done whilst growing up, Mia stripped the soaking spread from the settee. As Rosie disappeared upstairs, Mia then returned the four empty buckets to the kitchen. Wearing next to nothing, the teenager felt at ease and liberated, under no pressure to look perfect or disappoint anyone. Humming to herself as she cleaned, she wished that she could walk around the house naked like this more often. But that could never happen, not with her father around most of the time. Her parents were both on a business trip and wouldn't be back until tomorrow. So, Mia vowed to make the most of her new-found freedom, especially since it was starting to go dark outside.

Drawing the blinds to the kitchen, Mia began to eye up the four buckets. Knowing Rosie, she would take ages getting changed. She would have enough time to fill up the buckets and wait for her to come back down. After pelting her with water earlier, it was only fair that Mia return the favour, wasn't it? Turning on the radio to hide the side of running water, Mia filled up the buckets and waited at the foot of the stairs for Rosie to meet up comeuppance.

Wringing her sodden locks, Mia reflected that though she liked her light brown hair, growing up, she'd always wondered what it would be like to be blonde. Maybe, like Rosie, she could be the centre of attention, was that too much to ask, just the once? She'd often considered dyeing her hair when she was younger but had never had the nerve. She feared that she'd fail to measure up to her sister, who everyone would accuse her of trying to copy the look from. Though of course, she'd tried going blonde yesterday, when Rosie poured a bowl of custard all over her. Jessica may teasingly disagree, but Mia didn't think that that particular shade of blonde suited her at all. Furthermore, Mia had been the centre of attention then too, but not in the way that she'd always dreamt of.

Rosie, meanwhile, changed into her light blue, night slacks. Being older and more experienced, Rosie was far more at ease with her body. She oozed sexiness without even trying, both intentionally and not. Swiftly rummaging around her sister's bedroom, she picked out her lilac nightie and yellow knickers, before eventually finding a light green towel.

Holding her breath, Mia heard the first few footsteps of her sister began to descend down the stairs. Grabbing hold of the first bucket, Mia waited for the moment to launch her attack. "Thud, thud, thud", thumped her sister, as she continued to climb back down. Mia counted the steps, 'ten, eleven, twelve', she would soon be back down. The house had eighteen steps, two more and Rosie would be in range of her throw. But then, nothing. Rosie's thud had suddenly stopped. Five painful seconds passed as Mia waited for Rosie to finish climbing back down. But growing impatient, the teenager couldn't wait to discover what was holding her sister up. So, foolishly, Mia moved around to the foot of the stairs to have a look.

Instantly, Rosie threw a bucket of water of her own over the beautiful brunette, who screamed as she became utterly drenched once more. Shrieking, she launched the bucket in her grasp at her sister, who responded by shielding herself behind the green towel. Still completely dry, Rosie threw the damp towel over her sister's head and ran down to the foot of the stairs. Picking up Mia's second bucket, she threw it over the topless girl, just as she had groggily shaken off the towel. Realising that it was now her sister who was armed, Mia picked up the lilac nightie that Rosie had dropped on the stairs and launched it at the blonde. Narrowly missing, the nightwear instead landed in the third bucket, which Rosie thus dropped. Almost slipping over on the wet floor, Rosie picked up the final bucket and emptied it directly over her sister's head, before slapping the blinded, topless girl on the bottom and laughing.

Lifting the bucket off her head, Mia realised that the nightie and the towel were both now soaked. By some miracle however, the yellow panties had escaped the water fight. Shivering, Mia began to slide her sodden white panties down her legs, leaving herself completely in the buff. Basking in her victory, Rosie glanced down at her naked sister and marvelled at what she saw. Lavender was right, somehow, overnight, shy, retiring Mia had suddenly become smoking hot. Why weren't the guys fighting over her, she was the perfect catch? She would have to school her sister in men, for recently she seemed utterly disinterested in them all. Glancing down at Mia's breasts, she had to admit, that they were, however, disappointingly small. Perhaps, all guys cared about was a girl's chest, for she had a figure to die for. Nevertheless, though Mia lacked curves, she barely had an ounce of fat on her at all.

Feeling mischievous, Rosie darted passed her sister and picked up the panties, just as Mia reached out to put them back on. "Hey, give them here!" Mia retorted, annoyed. Waving them above the shorter girl, Rosie teased, "I shall, but not before I give you a thrashing, naughty girl!" Confused, Mia froze, before replying, "You serious? Rosie, what the hell?" "Yeah, you tried to pour water over me and now you must be punished", Rosie hollered back. Smiling, Rosie sat down on the stairs and pointed for Mia to lay across her lap. But then, completely unexpectedly, Mia did exactly just that.

Rosie had been joking of course, she thought her sister knew that. But now, Rosie felt the ticklish bristling of Mia's bush brush up against her thigh. Mia was her sister, this was way beyond being wrong. Perplexed, Rosie almost chickened out at the last second and began to order her sister to get back up. But then, she thought, Mia was her annoying, pesky, infuriating only sibling, how many of her friends would love to teach their younger sisters a lesson just like that? After another moment's pause, Rosie then heard her sister begin to laugh. "Who's the prude now Rosie? Are you too chicken to give me a slap?" Mia asked.

Brushing her breasts against her sister's knee, the naked brunette continued, "You know what, I've always, secretly, wanted to be spanked. Go on, admit it, you've always wanted to smack me, I can see it in your eyes. Go on, don't be shy." Shrugging her shoulders, Rosie raised her right hand and slapped it sharply against Mia's backside. Feeling her sister wiggle as she was slapped, Rosie goaded, "Come on, hold still, you've still got another nineteen slaps to withstand!" Smiling, she then spanked her sister a second time.

Giggling as her sister spanked her, Mia asked, "Rosie, have you ever been slimed?" "Oh no, Lavender's often tried to get me interested, but I've always made my excuses and claimed to have other plans", Rosie replied. Continuing to slap her sister, Rosie added, "Every now and then I've wondered what it would be like to have a bowl of custard tipped over me, but I've always, without fail, backed out. Every time Lavender asks me, I hear a caustic voice, in the back of my head, telling me that boys wouldn't like me if they saw me covered in gunk and smelling absolutely vile. Silly really, I've never been the greatest feminist, now have I?" "Well, maybe it's time you took the plunge", Mia replied, as she continued to get spanked.

Continuing, Mia explained, "Look, I need some help if I'm going to get my own back at Lavender, but there would be strictly no boys involved, of course, I absolutely draw the line at that." Slapping Mia's left cheek, Rosie remarked, "No boys involved? I certainly agree with you about that. I would love to see Mike's expression though if he knew what I was doing to you right now! But hey, a lack of guys wouldn't be a problem for you now would it? For I heard that you got a bit intimate with Jessica last night."

Caught off guard, Mia blushed and sighed. Pausing between slaps, Rosie remarked, "Hmm, I thought it was odd that you weren't showing any interest in guys. Correct me if I'm wrong, but there's been something brewing between you two now for a while. But Mia, please don't hate me when I say, I don't think Jessica means anything by it. She's still leaves the very desperate impression that she's utterly obsessed with hunky men and their rippling biceps. I mean, your chest is cute and lovely but you don't have a six pack Mia, do you now?" Rosie then gently pinched her sister's bottom before awaiting her sister's reply. "Oh Rosie, I think I love Jess, I can't help it, I know she likes guys. But honestly, it's all so confusing, for she was the one who instigated everything last night", Mia confided. "Well, if she shacks up with you, then maybe, just maybe, she will stop flirting with Mike. Jess has been all over him recently and he doesn't even have that much of a six pack!" Rosie joked, before giving her sister one final slap.

Ruffling her sister's hair, Rosie then gently pushed Mia off her lap. Rubbing her stinging, sore bottom, Mia then eagerly slipped on the yellow panties as Rosie had promised. Staring at her sister, Mia wondered whether she might just catch her off guard. "I'm going to have a glass of milk Rosie; would you like one?" "Yeah, sure, thanks", came her sister's rather nae reply. But then, watching her sister, dressed in nothing but her panties, saunter off to the kitchen, Rosie realised that Mia might just be hatching a dastardly plan. "But I'll come with you, I want to hear more about what happened last night", Rosie added.

Grumbling at being rumbled, Mia continued to the fridge regardless. Reaching inside, she found that the milk carton was trapped behind two watermelons, so she urgently searched for something else with which to attack. Trying to distract Rosie with compliments, the unclad brunette effused, "You know sis, you look stunning tonight, even in your slacks." Pausing for effect, Mia then added, "It would almost be a shame to destroy you in a food fight."

Startled, a sense of panic and foresight swept over the stunning blonde. Defensively, she squeaked, "Oh no, you're not getting me messy tonight Mia, I'm too tired and I have work tomorrow morning, perhaps some other time." But the plucky teenager wasn't taking no for an answer. Feeling a sudden shot of adrenaline, Mia picked up a can of whipped cream, resting on the bottom shelf. Twisting around, Mia took a large stride towards Rosie, cornering and trapping her between the breakfast table and the pot and pan rack. Realising that her situation was growing increasingly desperate, Rosie squirmed and placidly awaited her well-deserved comeuppance. Mia laughed at her big sister and took aim at her gorgeous cheeks and fired.

"Pfft", went the can of whipped cream, "pfft, pfft, pfft." There was nothing left in the can. Why would anyone put an empty can back into the fridge? It must have been her Dad. Mia shook the can and tried to squirt it a fifth time, but still nothing happened. Delighted, Rosie took the opportunity to squeeze past her sister and dove into the fridge. With Mia momentarily distracted, the blonde carefully weighed up her options. Smirking, Rosie purred, "Oh, Mia." Galled, the unfortunate light brunette turned around. Immediately, Rosie smashed a huge lemon meringue pie into her dainty, angelic face. Mia stood motionless in shock, as meringue slithered down her heaving chest and cream clogged up her eyes. Just like this morning, during breakfast at Lavender's, her attempt at revenge had spectacularly backfired.

Tauntingly, Rosie continued, "Sis, if you're going to squirt me with cream, always check that you have ammunition before firing. You should select your weapons better. For instance, this jug of cream would have made me far messier, as you're about to find out." Gleefully, Rosie grabbed the jug and poured it over her sister's already messy head. Poor, poor Mia; the cream and pie continued to dribbled down over her cleavage and soil her fresh, clean panties, she was a truly ridiculous sight.

Seeing the funny side, Mia stuck out her tongue and blew a raspberry. Inspired, Rosie picked up the nearby, almost completely full, can of raspberry sauce and began to squirt it over her sister's resplendent, yet gooey head. Feeling desperate, Mia looked around the kitchen for something with which to retaliate. But Rosie still blocked her access to the fridge and with her mum away for the past week, the cupboard was almost bare. Sensing her victory, Rosie unscrewed the lid off the raspberry sauce and dumped the entire remainder of the contents over Mia's face.

Thinking her assault finished, Mia began to wipe the cream and lemon curd from her eyes. But then, she heard the distinct sound of running water and glanced around to find Rosie filling up a bucket of water one final time. Taking flight, Mia darted out into the downstairs hall. Her sodden knickers slipping down, the crack of her backside became exposed as she ran. Following closely after her, just as she was about to launch the bucket, Rosie was startled to hear the familiar sound of the front door becoming unlocked. Pushing the front door open, in stepped their parents, returning home, a day early, from their business call. Glancing upwards, poor Mia, naked except for her yellow panties, stared straight into the eyes of her Mum and Dad. At the exact same moment, Rosie, unable to pull out in time, emptied the final bucket of ice cold water all over the unlucky, unclad lass.
