The Next Day...

The next morning, Rikki lay asleep in her bed. The soft light of the sun peeking through her window shades, bathing her body in dazzling golden light.

Slowly, Rikki began to stir, her head pulsating with the remnants of last night's festivities. Her mouth was parched, practically a desert. As her surroundings came into focus, she recalled the laughter, the drinks, and the party. But there was something else, a lingering taste on her tongue that was both familiar and unsettling.

Oblivious to the knowledge that what she was tasting was the remnants of Tara’s juices, Rikki simply chose to ignore the odd taste in her mouth.

Glancing at the clock, she noted it was past noon. She reached for the water bottle Tara had considerately left, the cool liquid quenching her thirst.

Her body felt light, almost weightless. At the same time, a dull ache between her legs made itself known.

Rikki stirred in her bed, her body still buzzing from the night before. The cool sheets against her skin felt like clouds, begging Rikki to sink deeper into them. She tried to recall the events of the previous night, her memories slowly resurfacing.

She remembered the laughter, the drinks, the party. The game of spin the bottle and the ensuing kisses. She remembered Tara's lips on hers, the taste of her sister's tongue, and the way her body had responded to her touch. The arousal, the heat between her legs, the quivering pleasure.

But Rikki also felt the shame. The shame of her actions with her sister. The shame of forcing her sister to kiss her. The shame of embarrassing Tara for a quick laugh.

To Rikki, Tara was the innocent, shy little sister. And Rikki’s actions the night before were not kind in Rikki’s sober mind. She felt a pang of guilt as she recalled the previous night's events. The taste of Tara's lips still lingered on her own, the memory of her sister's body pressed against hers still vivid in her mind.

Rikki shook her head, trying to clear her thoughts. She couldn't believe she had acted so recklessly. She had always taken pride in being a good sister, a role model for Tara. But last night, she had crossed a line.

Rikki was sure Tara understood. Rikki was belligerently drunk last night after all. But still, Rikki should try to make it up to Tara.

With a sigh, Rikki swung her feet off her bed and stood up. A brief spell of lightheartedness came and went as Rikki balanced herself. Her stomach turned, a consequence of the immense amount of **** she’d consumed the night before.

Rikki staggered towards her bathroom, indifferent to her nudity. The chill of the tiles underfoot sent a shiver up her spine as she navigated her way to the toilet. Her bladder was in dire need of relief, and she sighed in satisfaction as she relieved herself.

Seated there, she noticed an unusual stickiness on her thighs. Running her fingers along her inner thigh, she discovered traces of dried femcum. "Must have been a wild dream," she mused, attributing it to her high libido and the ****'s influence.

Unsteadily, she rose to her feet, catching her reflection in the bathroom mirror. Her short blonde hair was in disarray, standing in various directions. Her athletic physique bore the marks of her unruly night - a few minor bruises from stumbling into furniture while ****. Her ample breasts swayed as she moved, and she noticed her nipples were unusually sensitive this morning.

The persistent ache between her legs made her wonder if she'd masturbated before falling asleep. It wouldn't be out of character for her, given her typically high sex drive. She felt the familiar stirrings of arousal building again - her body's natural morning response.

Stepping into the shower, she turned on the water, letting it cascade over her tanned skin. The warm water helped clear her head slightly, though the hangover still lingered. As she began to wash herself, her hands brushed against her unshaved pubic area, sending a jolt of pleasure through her body.

"Damn," she whispered, realizing how aroused she was becoming. Her body was extra sensitive this morning, every touch seeming to ignite her nerve endings. She tried to focus on just cleaning herself, but her hands kept straying back to her erogenous zones.

“Oh fucking hell,” Rikki sighed, resigned to her bodies needs.

Lazily, Rikki began to massage her pussy. The slick juices of her arousal gushing out like a fountain.

Her fingers danced in well-rehearsed motions, teasing her engorged clit as the warm shower continued to pour over her toned body. Rikki leaned against the cool tiles, widening her stance as she yielded to her body's insistent demands. Her free hand reached up to knead one of her ample breasts, tweaking and twisting the sensitive nipple.

"Fuck," she murmured, her fingers gaining momentum. The mix of her hangover and heightened sensitivity made every touch feel electrifying. The smell of her arousal rising in the steamy air to Rikki’s nose. Nasty though it was, Rikki liked the smell of herself. It was comforting.

She inserted two fingers into herself, gasping at her own tenderness. The ache within her cunt intensified as she began to thrust her fingers in and out, her thumb still swirling around her clit. Her other hand persisted in massaging her breast, gripping the flesh firmly.

The steam from the shower filled the bathroom as Rikki's movements grew more frantic. Her legs quivered as she neared her peak, her fingers moving faster and harder. She could feel her walls beginning to tighten around her fingers.

"Oh god, oh god," she panted, her head thrown back against the shower wall. Her body was ablaze, every nerve ending crying out for release. She added a third finger, stretching herself further, the slight burn only enhancing her pleasure.

The familiar tension built in her lower abdomen, her muscles tensing as she neared her climax. Her fingers moved frenziedly now, her breathing coming in short, sharp gasps. The water continued to cascade over her body as she worked herself closer and closer to the edge.

With a final, sharp cry, Rikki's orgasm washed over her. Her body convulsed violently, her womanhood clenching rhythmically around her fingers as waves of pleasure coursed through her. Jets of her squirt sprayed the shower floor and walls like a sprinkler.

As Rikki's climax ebbed away, her legs quivered beneath her. She braced herself against the shower wall, her chest rising and falling with each breath. Her fingers remained buried deep within her, her inner walls still contracting with residual spasms. The warm water continued to cascade over her sensitive skin as she gradually withdrew her fingers.

"Damn," she murmured, observing her juices mingle with the shower water and spiral down the drain. Her body felt both sated and somehow still craving more. The pounding headache from her hangover had temporarily subsided, replaced by the pleasant hum of post-orgasmic euphoria.

She glanced down at her body, noticing her nipples were still erect and sensitive. The water droplets trickling down her breasts made her shiver. Her unshaved pubic area was flattened by water and her own wetness, and she could still feel the faint pulse between her legs.

Rikki reached for the soap, squeezing a generous amount onto her loofah. She began to scrub herself thoroughly, paying particular attention to her inner thighs where remnants of her fluids clung to her skin. The scent of her arousal lingered in the steamy air, mingling with the fresh fragrance of her soap.

As she washed, her mind drifted back to the previous night. The memory of Tara's kiss floated unbidden into her thoughts, causing an unexpected flutter in her stomach. She quickly dismissed the thought, attributing it to the lingering effects of **** and her post-orgasmic bliss.

"Pull yourself together, Rikki," she chided herself, focusing on rinsing the soap from her body. Her muscles still felt loose and relaxed from her climax, but her head was starting to throb again as the hangover reasserted itself.

She tilted her face up into the shower spray, letting the warm water run over her features. The last amounts of soap being washed away. Clean and deeply satisfied, Rikki turned the shower off.

Emerging from the shower, Rikki grabbed her towel, her wet feet leaving dark prints on the bathroom mat. The cool air met her damp skin, causing a wave of goosebumps to ripple across her flesh. Her nipples hardened in response to the sudden temperature change, prompting her to swiftly wrap the large towel around her body.

Water droplets from her short blonde hair trickled down her shoulders as she stood before the slightly fogged mirror. She wiped away the condensation with her hand, revealing her flushed reflection. Her blue eyes still held the lingering traces of arousal, her cheeks rosy from the hot water and her recent activities.

She felt another wave of desire building between her legs, causing her to groan in frustration. "Not again," she muttered, tightening her thighs together. Her libido had been increasingly hard to control lately, and she wondered if a doctor's visit was in order.

Running her fingers through her wet hair, she noticed the bathroom door wasn't fully closed. A sliver of the hallway was visible through the gap, and for a moment, she thought she saw a shadow move. "Hello?" she called out, but there was no response.

Dismissing her paranoia, Rikki adjusted her towel and grabbed a smaller one to dry her hair. As she rubbed her head vigorously, water droplets scattered around the bathroom. Her body was still humming with residual pleasure, making even the soft terry cloth feel sensual against her skin.

With her body tightly wrapped in towels, Rikki makes her way back to her bedroom to get dressed for the day.

Entering her bedroom, Rikki detected an unusual heaviness in the atmosphere, as if the air was infused with an unseen ****. Her damp feet marked the hardwood floor as she navigated towards her dresser. The morning sunlight seeped through her curtains, bathing her room in a gentle radiance.

She halted, detecting a faint rustle from somewhere within the house. "Tara?" she queried, but was met with only silence. Brushing it aside, she let her towel pool at her feet, baring her toned physique to the cool air. Her skin tingled with goosebumps, and she felt her nipples harden once more in response.

Her hands roamed over her body, unable to ignore the heightened sensitivity. Her fingers traced the contours of her breasts, and she suppressed a groan, resisting the urge to indulge herself again. "Concentrate," she murmured, attempting to disregard the insistent pulsing between her legs.

She opened her dresser drawer, seeking out fresh undergarments. As she leaned down, droplets from her hair trailed down her back, causing a shiver.

Rikki, very well practiced at ignoring her bodies incessant arousal, dresses herself. Dawning a clean, basic white T-shirt overtop a black sports bra. A clean, gray pair of panties her choice of underwear. Finally, a simple pair of grey sweatpants to finish her relaxed outfit.

Securing her damp hair with a band, Rikki observed her reflection in the mirror. Despite her casual attire, the curves of her body were still pronounced beneath the fabric. Her white t-shirt, slightly adhering to her damp skin, revealed the silhouette of her sports bra.

She perched on the edge of her bed, her body still humming with lingering desire. The gentle friction of her sweatpants against her sensitive skin was palpable as she adjusted her position. Her heightened libido was becoming increasingly challenging to manage, prompting a deep sigh.

Raking her fingers through her tied-back hair, she noticed her pillow was slightly askew. She leaned over to straighten it and detected an unfamiliar scent. Frowning, she leaned closer, but couldn't identify it. Perhaps it was time to do laundry.

Rising to her feet, a wave of dizziness from her hangover washed over her. "I desperately need coffee," she murmured, bracing herself against the bedpost. The room swayed slightly, and she took a deep breath to steady herself.

As she approached her bedroom door, she heard movement in the hallway once more. This time, she was certain it wasn't a figment of her imagination. "Tara?" she called out, her voice echoing in the silence.

A moment passes before Rikki hears a response, “Yeah?” Tara’s voice calling out from the other end of the hallway towards the kitchen.

"Are you brewing coffee?" Rikki inquired, her voice still rough from the previous evening's activities. She leaned against the doorframe, fighting off another bout of dizziness.

"Yes... Would you like some?" Tara's voice wafted back, punctuated by the soft clinking of mugs.

Rikki navigated down the hallway, her hand gliding along the wall for balance. The wooden floor felt cool under her feet, and the enticing aroma of fresh coffee grew stronger with each step.

Upon entering the kitchen, she found Tara huddled over the coffee maker, her long black hair veiling her face. Rikki noticed her sister's hands quivering slightly as she portioned out the coffee grounds.

"Is everything alright?" Rikki asked, settling into one of the kitchen chairs. "You seem a bit unsteady this morning." She observed as Tara's shoulders stiffened at the inquiry.

"I'm fine," Tara muttered, maintaining her back turned position. "Just... exhausted from last night." She occupied herself with the coffee preparation, her actions deliberately controlled.

Rikki shrugged at Tara’s words, “God my head hurts. How much did I drink last night?” Rikki groaned, leaning over the table.

"A lot," Tara murmured, her gaze fixed on the coffee maker. "You had quite a few shots during the game." Her voice wavered as she recalled the previous night's events, particularly the impulsive kiss they had shared.

The coffee maker gurgled and hissed, releasing a rich aroma into the kitchen. Tara's hands trembled as she retrieved two mugs from the cabinet. She could sense Rikki's presence behind her, causing her heart to race. The memory of her actions while Rikki slept was still vivid in her mind, filling her with a mix of guilt and arousal.

"Did I do anything embarrassing?" Rikki asked, massaging her temples. She shifted in her chair, the fabric of her sweatpants creating a subtle friction that reminded her of her lingering arousal. Her sports bra felt constricting against her sensitive breasts, and she resisted the urge to adjust it.

Tara's breath hitched. "No... nothing really," she lied, pouring the steaming coffee into the mugs. "Just the usual party antics." She added cream to Rikki's coffee, knowing her sister preferred it that way.

Rikki accepted the mug with a grateful smile, her fingers brushing against Tara's as she took it. “Thanks, you’re the best.”

Tara's heart fluttered at the brief contact, her mind flashing back to the intimate moments she had shared with her sleeping sister just hours ago. She watched as Rikki took a long sip of coffee, her eyes following the movement of her sister's throat as she swallowed.

"Mmm, this is exactly what I needed," Rikki murmured, closing her eyes in appreciation. She shifted in her chair again, trying to find a comfortable position that wouldn't aggravate her heightened sensitivity.

Tara settled into the chair across from Rikki, her own coffee untouched. She couldn't tear her eyes away from her sister's damp hair, remembering how it had felt between her fingers last night. The way droplets of water now trailed down Rikki's neck made her mouth go dry.

"I think I'm going to need another shower later," Rikki commented, running her fingers through her damp hair. "I still feel gross from last night." She adjusted her white t-shirt, which had begun to cling to her skin where it was still slightly wet from her shower.

The movement caused her breasts to shift beneath her sports bra, and Tara had to **** herself to look away. She took a sip of her coffee, using the mug to hide her flushed face. The taste was bitter in her mouth, but she welcomed the distraction.

"You know," Rikki continued, oblivious to her sister's internal struggle, "I had the strangest dream last night. Can't remember much of it, but..." She trailed off, her brow furrowing in concentration. "It felt so real."

Tara's hand trembled, causing her coffee to slosh dangerously close to the rim of her mug. "Oh?" she managed to squeak out, her heart hammering in her chest. "What kind of dream?"

“The good kind,” Rikki chuckled, insinuating a naughty dream. “Think it was something to do with Joanna? Can’t remember the details very well.”

Tara's heart plummeted at the mention of Joanna. She tightened her grip on the coffee mug, her knuckles blanching. The thought of Rikki dreaming about Joanna instead of recalling the actual events stirred a bitter pang of jealousy in her.

Rikki squirmed in her seat once more, crossing and uncrossing her legs. The movement drew Tara's attention to the way the gray sweatpants clung to her sister's toned thighs. "I'm still so sensitive," Rikki murmured, seemingly to herself.

"Perhaps you should rest a bit longer," Tara proposed, her voice barely audible. She watched as a droplet of water trickled from Rikki's damp hair onto her white t-shirt, creating a small damp spot that made the fabric slightly sheer.

"No, I need to stay awake," Rikki replied, taking another long sip of her coffee. "I got plans later." She reached up to adjust her sports bra again, the movement causing her breasts to jiggle slightly beneath her shirt.

Tara couldn't help but stare, recalling how those breasts had felt in her hands just hours ago. She quickly averted her gaze when Rikki glanced her way, hoping her sister hadn't noticed her lingering stare.

"Are you alright, Tara? You seem a bit off," Rikki inquired, her voice filled with genuine concern. She leaned forward, placing her hand on the table near Tara's.

The proximity made Tara's breath hitch. "I'm fine," she managed to say, "just tired from last night." She could smell Rikki's body wash, the fresh scent transporting her back to her actions while her sister slept.

Rikki ran her fingers through her hair again, unintentionally flexing her arm muscles. The movement evolving into a stretch, one that **** the fabric of her shirt to strain against her large chest.

Tara's gaze lingered on the outline of Rikki's breasts beneath her damp shirt, the memory of their softness still vivid in her mind. She shifted in her seat, attempting to quell the growing warmth within her.

"I could use another cup of coffee," Rikki declared, rising from her chair. Her sweatpants hugged her hips, accentuating her curves as she moved towards the coffee maker. Tara's eyes followed her sister's graceful stride, captivated by the way the morning light danced in her damp hair.

"Care for a refill?" Rikki asked, glancing back with a smile. Tara shook her head, clutching her mug tightly as she watched Rikki reach for the coffee pot. Her shirt rode up slightly, revealing a sliver of skin at her waist.

Rikki groaned softly as she stretched to grab the sugar from the top shelf, her muscles flexing beneath her damp shirt. "I'm so sore today," she murmured, rolling her shoulders. "I must've slept funny."

Tara felt a pang of guilt, knowing the true cause of Rikki's discomfort. She took a sip of her cold coffee, the bitterness a stark contrast to the sweet tension in the room.

"It's strange," Rikki continued, stirring her fresh coffee. "I woke up completely naked. I never sleep without clothes." She chuckled, shaking her head. "I guess I was really drunk last night."

Tara's spoon clattered against her mug. "Maybe you got hot in the night," she suggested, her voice barely audible. She watched as Rikki leaned against the counter, her hand absentmindedly rubbing her thigh.

"Yeah, maybe," Rikki nods, “Or maybe I got horny.”

Tara’s face turns pink at Rikki’s words, and Rikki laughs at Tara’s expression. “God girl! Lighten up!” Rikki laughs, “we’re both adults, we can joke about that stuff sometimes.” Tara fidgets in her seat, her gaze following Rikki as she takes another sip of her coffee. The sight of her sister's lips on the mug triggers a vivid memory of those same lips against her fingers.

"It's completely normal," Rikki continues, unaware of Tara's discomfort. "Everyone has needs, right?" She stretches, revealing a strip of skin above her waistband.

Tara's mouth goes dry, her eyes drawn to a water droplet tracing down Rikki's neck. "Y-yes," she stammers, her hands shaking as she puts down her mug.

"Actually," Rikki says, rolling her shoulders, "I'm feeling a bit... you know." She checks the time. "I might need another shower." She runs her fingers through her damp hair, causing her shirt to strain against her chest.

The casual remark sends a shock through Tara. She knows exactly what Rikki means - her sister's high sex drive is no secret. Tara watches as Rikki shifts again, crossing and uncrossing her legs.

"Sorry if that's too much information," Rikki chuckles, taking another sip of coffee. "But hey, that's what sisters are for, right? Being honest with each other?" She winks at Tara, oblivious to the impact of her words.

Tara nods silently, her mind filled with images of her actions towards Rikki while she slept. The guilt mixes with arousal as she watches her sister squirm, clearly affected by her heightened libido.

“At least, I should do something about it before I meet with Joanna later.” Rikki mentions.

Tara’s stomach churns, jealousy rising through her lust and shame. “What’s the deal between you two? Dating or what?”

Rikki chuckles, shaking her head. "No, nothing like that. Joanna and I are just friends who sometimes... well, you know." She trails off, shifting in her seat again. "Sometimes things happen when we drink."

The casual admission makes Tara's chest tighten. She watches as Rikki stretches again, her shirt riding up to reveal more of her toned stomach. The sight sends a fresh wave of desire through her body.

"Speaking of which," Rikki continues, running her fingers through her damp hair, "I really need that shower." She stands up, adjusting her sports bra through her shirt. "I'm so worked up right now, I can barely think straight."

Tara's breath catches as she watches Rikki move. Her sister's sweatpants cling to her curves, and Tara can't help but remember how those curves felt under her hands just hours ago.

"You know what's weird though?" Rikki says, pausing at the kitchen doorway. "I keep tasting something... familiar." She licks her lips unconsciously, making Tara's heart skip a beat. "Like, from last night or this morning, I'm not sure."

Tara nearly chokes on her coffee, knowing exactly what that taste is. She sets down her mug with trembling hands, trying to keep her voice steady. "Maybe it's just the **** from last night?"

"Maybe," Rikki muses, leaning against the doorframe. She shifts her weight from one foot to the other, the movement causing her breasts to bounce slightly under her shirt. "But it's different. Almost like..." She pauses, brow furrowing in concentration.

Tara holds her breath, terrified that Rikki might somehow remember what happened. But her sister just shakes her head, giving up on the thought.

“I don’t know,” Rikki sighs. “Anyway, what about you? What are you doing today?”

Tara gulps, relief filling her lungs with air. “Oh, nothing. Probably watch a couple live streams and maybe play some Fortnite.”

Rikki chuckles, “God you’re such a nerd. I love it.” Tara's heart skips a beat as Rikki speaks, her emotions a jumbled mix of desire and guilt. She watches her sister squirm, the arousal evident in her movements.

"I really need to deal with this," Rikki says, her fingers playing with her damp hair. Her cheeks are flushed, her body language screaming of her heightened libido.

Tara nods, her own body responding to Rikki's state. She can't help but notice the way Rikki's white t-shirt stretches across her chest as she adjusts her sports bra.

Rikki chuckles, seemingly oblivious to Tara's intense gaze. "Sometimes I wonder if this runs in the family," she muses, her hand tracing a path down her stomach.

Tara's mind races with memories of the previous night. "I... I wouldn't know," she manages to stammer out, her voice barely audible.

Rikki stretches, her sweatpants slipping low on her hips. "Sorry, I'm probably making you uncomfortable," she apologizes, giving Tara a small smile.

"No, it's... it's fine," Tara replies, her eyes drawn to the strip of skin between Rikki's shirt and sweatpants. She can see the outline of Rikki's gray underwear peeking above the waistband.

Rikki shifts her weight, pressing her thighs together. "God, I really need to..." she trails off, biting her lower lip. "I'll be quick, I promise. Then maybe we can hang out before I meet Joanna?"

Tara's jealousy surges at the mention of Joanna, but she forces herself to nod. “Yeah. Sure thing. You just,” Tara pauses as she looks at Rikki’s crotch, “take care of…that.”

Rikki nods, her cheeks flushed. "I won't be long," she promises, her fingers fidgeting with the hem of her shirt.

Tara watches as her sister leaves the room, her heart pounding in her chest. She can't help but feel a mix of guilt and desire, her mind filled with images of the previous night.

She takes a deep breath, trying to steady her nerves. She knows she needs to focus on something else, to distract herself from these inappropriate thoughts.

Tara glances at her laptop, the screen still open to the live stream she was watching earlier. She tries her hardest to watch the stream and not think naughty things about Rikki. But Tara’s lust is too strong.

With a sigh, Tara gets up from the table and creeps along toward Rikki’s bathroom. The sounds of running water and Rikki’s muffled moans emanating from behind the door.

Tara's heart races as she presses her ear to the door. She hesitates, her conscience battling with her desire. The guilt of her actions the previous night still weighs heavily on her, but her attraction to Rikki is undeniable.

She leans against the door, her breath hitching as she hears her sister's soft gasps. The thought of Rikki in the shower, her body slick with water, sends a shiver down Tara's spine. She knows she should leave, but her feet remain rooted to the spot.

Rikki's moans grow louder, the sound sending a wave of heat through Tara's body. She can't help but imagine Rikki's hands roaming over her wet skin, her fingers slipping between her thighs. The image is so vivid, Tara can almost feel the water droplets on her own skin.

Tara's hand hovers over the doorknob, her heart pounding in her chest. She knows she shouldn't, but the temptation is too strong. She turns the knob slowly, the sound of the shower masking the soft click.

The steam hits Tara as she opens the door, the scent of Rikki's body wash filling her nostrils. She can see Rikki's silhouette through the shower curtain, her body moving rhythmically. Tara's breath catches in her throat as she watches, her own body responding to the sight.

Rikki's moans grow louder, her movements more frantic. Tara can't tear her eyes away, her own desire growing with each passing second. She knows she should leave, but her body refuses to move.

As Tara observes Rikki, her gaze turns downward to the pile of Rikki’s clothes on the floor. A pair of grey panties a top the clothes pile.

With a trembling hand, Tara reaches out and picks the underwear up off the floor, careful to not make her presence known.

The fabric is still warm from Rikki's body, and Tara can't help but bring it to her face, inhaling deeply. The scent of Rikki's arousal is intoxicating, and Tara feels a surge of desire that she can't ignore.

She closes her eyes, imagining herself in the shower with Rikki, their bodies pressed together as they explore each other's curves. The thought is so intense that Tara can't help but touch herself, her fingers slipping beneath her own clothes as she imagines Rikki's hands on her body.

But as she loses herself in the fantasy, Tara can't shake the feeling that she's crossing a line. She knows that what she's doing is wrong, that she should leave and give Rikki her privacy. But the desire is too strong, and Tara can't bring herself to leave.

Tara’s fingers greet the slick skin of her pussy as she inhales Rikki’s scent. Her palm rubbing her clit as her fingers dig inside her. Rikki’s moans from behind the shower curtain accentuate Tara’s actions as her body hums with pleasure and lust.

“Oh fuck, Tyler you’re so big.” Rikki murmurs.

Tara suppresses a moan as her climax draws near. With a deep, shuddering breath, Tara presses her fingers more deeply into her wetness, her other hand clutching the fabric of Rikki's underwear. The sound of Rikki's pleasure, the thought of Tyler, sends a pang of jealousy through Tara, but it only intensifies her own arousal.

In the shower, Rikki's moans crescendo as she imagines Tyler's touch, her body tingling with the sensation of her own fingers working in tight, frantic, rhythmic movements. She leans against the shower's tiled back, her legs trembling, the water's heat doing almost as much to stave off the morning's lingering hangover as the orgasm that's quickly becoming unescapably close.

Tara's breath becomes a stuttering whisper of Rikki's name as she feels the first wave of her orgasm begin to crest. Her eyes flit between the shower curtain and the underwear in her hand, the scent of Rikki's arousal still clinging to the fabric. She can't help but imagine that it's Rikki's hand touching her, Rikki's breath on her skin, Rikki's lips whispering how much she needs this.

Together, the sisters both cum. Rikki, oblivious to Tara’s presence, cries out loud as she squirts furiously. Her orgasm making her body convulse and her knees buckle.

Meanwhile, Tara’s orgasm is silent. Her eyes rolling back in her head as she bucks her hips. The scent of Rikki’s underwear ingraining itself in Tara’s mind.

She leans against the bathroom door, her body still quivering from the aftermath of her climax. The echoes of Rikki's pleasure continue to fill the room, unaware of her sister's presence.

As the tremors in her legs begin to subside, Rikki takes a deep breath, steadying herself against the shower's tiled wall. The water continues to cascade down her body, the heat slowly bringing her down from the peak of her orgasm. She closes her eyes, relishing the feeling of release, the tension in her body gradually dissipating.

Tara, still basking in the afterglow of her own release, takes a moment to compose herself. She looks down at the underwear in her hand, the fabric still moist from her touch. With a twinge of guilt, she carefully folds the underwear and replaces it on top of Rikki's clothes, ensuring not to leave any signs of her presence.

With a soft sigh, Tara turns to leave, her heart pounding in her chest. But as she reaches for the doorknob, she hears the water in the shower begin to soften, a signal that Rikki is about to finish.

Tara's eyes widen in panic. She quickly and as quietly as possible, scrambles to the door. She slips out of the bathroom, pressing her back against the hallway's wall.

Tara's heart races as she hears the bathroom door open behind her. She quickly tiptoes away, her heart pounding in her chest. She rushes back to her room, her mind a whirl of thoughts and feelings. She closes the door behind her, her breaths coming in quick, shuddering gasps. She leans against the door, her body still trembling from the adrenaline.

In the bathroom, Rikki steps out of the shower, a towel in her hand. She dries herself off, her mind still hazy from the aftermath of her orgasm.

She quickly dries herself off and redresses in her outfit. She shakes her head at herself in the mirror as she admonishes herself for two showers in under an hour. “But, a girl has needs” she whispers to herself.

Finally, her arousal subsides. With a deep breath and a smile, Rikki exits the bathroom and heads off towards Tara’s room.

Inside, Tara tries her best to look casual. Her shame adding to her flushed face that shows the aftermath of her own climax. A knock at her door startles her.

"Come in," Tara calls out, her voice still trembling as she hastily straightens her attire and attempts to steady her breath.

Rikki enters, her damp hair leaving small droplets on her blouse. "Hey, I'm off to meet Joanna shortly. Just checking if you need anything before I leave?"

Tara's gaze involuntarily follows the contours of Rikki's figure beneath her clothes, her sister's scent still lingering on her fingers. She quickly hides her hands under her thighs. "N-no, I'm fine. Thanks though."

"Are you certain? You seem a bit flushed," Rikki says, moving closer. She reaches out to check Tara's forehead, causing Tara to flinch slightly. "Are you feeling alright?"

Rikki's nearness accelerates Tara's heartbeat once more. She can detect the fresh shower gel on her sister's skin, blended with the distinct scent that is purely Rikki. "Just... just a bit warm," she stammers.

"Perhaps you should open a window," Rikki suggests, moving to do so. As she stretches up, her blouse rides up slightly, revealing a strip of tanned skin that leaves Tara's mouth dry.

Tara watches as Rikki adjusts the window, her muscles flexing with the movement. She feels a fresh wave of desire and guilt surge through her, recalling her actions in the bathroom.

"That should help," Rikki says, turning back to Tara. She runs her fingers through her damp hair, sending more droplets onto her blouse. A thoughtful look crosses her face as she looks at Tara, “Hey. Are we cool?”

“What?” Tara asks nervously, “why wouldn’t we be?”

“Just, last night,” Rikki says.

Tara’s eyes widen in horror. “Oh my god. Rikki I’m so sorry. I didn’t think you were aware. I’m so sorry I never should’ve…”

“Woah, woah, woah!” Rikki holds her hands up in a passive gesture, “Calm down. It’s totally okay.”

Tara baulks at Rikki, “It… it is?”

Rikki smiles, “Of course it is. Fuck Tara, I’m so sorry I made you feel so awkward. I never should’ve kissed you last night. It was too much. I know you don’t drink like I do.”

Tara couldn’t believe her ears, once more relief washed over her. Her thoughts ring out, ‘Oh god, she was talking about the kiss at spin the bottle. She has no clue about what I did as she slept!’

“Oh, yeah no,” Tara sighs, “We’re cool. Totally.”

Rikki grins, her fingers combing through her damp locks. “I was worried I’d made things awkward between us.”
