Chapter Text
"You're up, Oosawa!" the PE teacher called out, snapping Aya out of her daze. She had been staring at the soccer ball, her thoughts wandering to the latest Foo Fighters song. A yawn slipped out, and she glanced over at Mitsuki, who was already jogging onto the field.
Mitsuki's legs, clad in black sports shorts, moved with a grace that seemed almost out of place on the well-trodden grass. Aya couldn't help but admire the way her muscles flexed with each stride, a silent pattern of power and agility. Her pink-ish eyes followed Mitsuki's figure as she passed, taking in the way her athletic body glided through the air as she kicked the ball. There was something mesmerizing about her girlfriend's lithe frame, something that made Aya's heart race in a way that had nothing to do with the exertion of the game.
As the match progressed, the girls' breaths grew heavier, their cheeks flushed with exertion. A sudden gust of wind played with the hem of Mitsuki's shirt, lifting it just enough to reveal the edge of her sports bra. Aya's eyes widened, and she felt a blush creep up her neck, a jolt of something electric shooting through her. The sight of Mitsuki's skinny, yet toned stomach and the hint of her back muscles was unexpected.
When the bell finally rang, signaling the end of class, Aya couldn't help but sneak glances at Mitsuki as they all trudged towards the locker room. She had never seen her like this before, not in their stolen moments at home or in the privacy of their secret dates. The sports bra, the sweat, the way her hair stuck to her forehead - it was all so... different. And hot.
In the locker room, the air was thick with the scent of perspiration and the clatter of metal lockers. Aya fumbled with her combination, her mind racing with thoughts of Mitsuki's barely concealed physique. She could feel her own heart thumping in her chest as she watched her girlfriend, who was a few lockers down, casually wiping the sweat from her face with a towel. The sight of Mitsuki's toned arms, the play of muscles under her loose school shirt, was driving Aya crazy. How did she not notice it earlier?
Mitsuki, seemingly oblivious to Aya's intense gaze, took off her glasses and started to wipe them down with the corner of her shirt. The simple act sent Aya's thoughts spiraling into a whirlwind of uncharted territory. Only now she started to think and look at Mitsuki this way, when they started dating she was simply too shy for it, but now... Seeing her like this, sweating, stripped down to the bare essentials was something else.
Mitsuki looked over, catching Aya's eye. "Hey, you okay?" she asked, a hint of concern in her voice. "You're looking a bit... flustered."
Aya managed a nervous laugh, her cheeks burning. "Yeah, I'm fine. Just tired from the game." She didn't dare tell Mitsuki the real reason for her flustered state. Instead, she focused on the task at hand, changing out of her PE clothes and into her school uniform. The fabric of her shirt felt sticky against her skin, and she couldn't wait to get home and take a shower.
"So, about that study session today," Mitsuki began, her voice low and casual. "Is it still on?"
"Yeah," Aya replied, her voice a bit too high-pitched. "It's still on."
Mitsuki nodded, a small smile playing on her lips as she slung her bag over her shoulder. "Good," she said, taking a step closer to Aya. Before Aya could react, Mitsuki leaned in and gave her a quick hug, her body still warm from the game. "See you at 6, then," she murmured, the scent of her sweat and the faint aroma of hery shampoo enveloping Aya. Then she was gone, leaving Aya standing there, her heart hammering in her chest.
The moment the locker room door closed behind Mitsuki, Aya let out a shaky breath she didn't realize she was holding. The feeling of Mitsuki's arms around her lingered, and she found herself replaying the moment in her mind. It was so unlike their usual interactions in school, where they had to be careful not to give away their secret. A mix of excitement and anxiety bubbled up within her as she thought about what the evening might bring.
Once home, Aya peeled off her sweaty clothes and stepped into the shower. The hot water cascading down her body did little to wash away the images of Mitsuki's athletic form. Instead, they grew more vivid, each droplet seeming to trace the lines of muscles she hadn't noticed before. She felt a strange mix of emotions, part shyness and part desire, as she soaped herself up. The water turned cold, and she realized she had been lost in thought for far too long.
Drying off, she stared at her reflection in the mirror. Her eyes searched for something, but she couldn't quite put her finger on it. She slipped in clean clothes and laid down on her bed, the plush comforter enveloping her like a warm embrace. Her thoughts kept drifting back to Mitsuki, her mind racing with the unexplored facets of her girlfriend's body.
Guilt nibbled at the edges of her consciousness. They hadn't talked about this, hadn't taken their relationship to that level. But the desire was there, pulsing through her veins like a secret heartbeat. Aya took a deep breath and locked her bedroom door, the click echoing in the quiet of her thoughts. She needed this, needed to understand what was happening to her.
Her hand slid under her shirt, tracing the curves of her stomach, feeling the warmth of her skin. Aya's eyes fluttered closed, and she imagined it was Mitsuki's hand exploring her, learning her body as intimately as she knew her own. Her breath hitched as she touched the bare skin of her hip, the sensation shooting through her like a spark. The guilt was still there, a whisper at the back of her mind, but it was quickly drowned out by the insistent beat of her pulse.
Her fingers found the edge of her panties, and she hesitated for a moment, her mind racing with the possibility of going further. But she couldn't shake the feeling that it wasn't right, that she was betraying their unspoken agreement. They had kissed, held hands, and cuddled, but the thought of taking it to the next level while Mitsuki wasn't even in the room made Aya's stomach churn with guilt.
The desire was undeniable, though. She pushed the fabric aside and let her fingertips graze her most sensitive spot. The touch was tentative at first, a gentle exploration that mirrored the way she had seen Mitsuki handle her guitar strings. A soft gasp escaped her lips, and she bit down on the pillow to muffle the sound. Her imagination painted vivid images of Mitsuki's strong hands, her confident touch, and the way she had looked at Aya during their most intimate moments.
Suddenly, the sound of a knock at the door pierced the silence. Aya's eyes shot open, and she froze, her hand still trapped between her legs. Panic set in as she realized she had been so lost in thought that she hadn't even heard Mitsuki arrive. She quickly adjusted her clothes, her heart racing as she called out, "Coming!"
Her legs felt wobbly as she stumbled to the door, her skin still flushed and damp with sweat. She took a deep breath, trying to compose herself before turning the knob.
Mitsuki was standing in the hallway, her school bag slung over one shoulder and her eyes looking a bit surprised. "Hey, I hope I'm not too early," she said, a hint of a smirk playing on her lips.
But when Aya opened the door, the smirk faded into a look of concern. Aya's face was flushed, and her eyes had a glazed-over look that Mitsuki hadn't seen before. "Aya, are you okay?" she asked, stepping closer. "You look...different."
Mitsuki's gaze searched Aya's eyes, and she reached out to touch her forehead. "You don't feel warm," she said, her brow furrowing. "But you look...flustered."
Her hand lingered on Aya's face, and the warmth of her touch sent another jolt through Aya's body. She swallowed hard, trying to push down the rising tide of guilt and desire. "I'm fine," she repeated, her voice a little more firm this time. "Let's just get started on the studying."
Mitsuki's eyes searched Aya's for a moment longer before she nodded, dropping her hand. "Alright," she said, her tone still gentle. "But if you need anything, you know I'm here."
They settled into Aya's room, books and notes spread out on the floor. The atmosphere was charged, the air thick with unspoken tension. Every time their fingers brushed against each other while reaching for a textbook or a pen, Aya felt a spark of electricity. She tried to focus on the homework, but her mind kept drifting back to the locker room, to the way Mitsuki had looked in her sports bra and shorts.
The room grew warmer, despite the cool evening outside. Aya found herself fidgeting, her eyes straying from her textbook to Mitsuki's profile. The way the light from the desk lamp painted shadows on her sharp cheekbones and highlighted the mole beneath her eye was incredibly distracting. Just as Aya was about to suggest taking a break, she heard the sound of her mom's heels clicking down the hallway.
"Girls, I'm taking Aki and Amu to the cinema," she called out, popping her head into Aya's room.
"Okay, Mom. Have fun" Aya responded, her voice a tad too eager. A moment later, the door slammed shut, and the sound of their mother's heels retreated down the hallway.
The silence that followed was filled with a sudden, palpable tension. Aya's mom's departure was like a dam breaking, and the rush of relief washed over both of them. Without missing a beat, Mitsuki pushed aside their schoolbooks and closed the distance between them, her hand reaching for Aya's. "You know, we don't have to study if you don't want to," she murmured, her voice worried.
Aya's cheeks grew even redder as she took Mitsuki's hand, her heart racing. "No, I'm fine," she assured her, trying to ignore the way her palms were sweating. "I was just... thinking about you."
Mitsuki's eyes searched hers, the concern etched deep. "What about me?" she questioned, her thumb stroking the back of Aya's hand in a soothing rhythm. The words hung in the air between them, and Mitsuki's expression grew soft, her eyes searching Aya's face for any sign of fever or illness. But all she found was a look of adoration that made her heart stumble.
"Aya," she said gently, "you're acting really strange. Did something happen at school today?"
Aya felt a knot tighten in her stomach. She hadn't meant to make Mitsuki worry, but she couldn't shake the overwhelming feelings that had been swirling around her all day. She took a deep breath and leaned in, her eyes locked on Mitsuki's. "It's just... I was looking at you during PE today," she whispered, her voice trembling slightly. "You were so... Hot."
Mitsuki's eyebrows shot up in surprise, a blush spreading across her cheeks. "Me?" she questioned, her voice barely above a murmur. "Why?"
Aya's heart was racing, but she knew she had to tell the truth. "You looked so... powerful," she admitted, her voice barely a whisper. "I couldn't stop thinking about it."
Mitsuki's blush deepened, and she looked away, a hint of a smile playing on her lips. "I've never heard anyone say something like that about me before," she said, her voice tinged with amusement. "But I'm flattered."
The air between them grew heavy with a tension that was both new and exhilarating. Mitsuki's smile grew wider, her eyes sparkling with curiosity. "What exactly were you thinking?" she prodded, her voice low and teasing.
Aya's heart felt like it was going to burst out of her chest. She took a deep breath and leaned closer, her voice barely audible. "I was thinking about how much I want to... touch you," she confessed, her cheeks burning with embarrassment. "How much I want to see and touch all of you. How much I want you to do the same to me."
Mitsuki's smile faltered, and she searched Aya's eyes, looking for any sign of insincerity. But all she found was a raw, unbridled desire that mirrored her own. She leaned in, her breath warm against Aya's cheek. "Then touch me," she whispered, taking Aya's hand in her own.
Aya's eyes went wide with shock, her face red, but she didn't pull away.
Mitsuki took a deep breath and leaned in closer, her own hand sliding beneath the fabric of her shirt. She placed Aya's trembling hand on her stomach, the warmth of her skin a stark contrast to Aya's cool palm. She felt Aya's pulse quicken, and a smug satisfaction settled in her chest. This was it. They were crossing the line they had so carefully drawn in the sand of their relationship.
Her hand moved upward, guiding Aya's to trace the curve of her ribs, then the soft swell of her chest. Aya felt like she was going to die from embarrassment, but she didn't pull away. Instead, she swallowed hard and allowed Mitsuki to show her the way.
Mitsuki's skin was hot and damp, and Aya's hand felt clammy in comparison. She was acutely aware of every inch of Mitsuki's body, every breath she took. Her heart was hammering in her chest, and she could feel the blood rushing to her cheeks. But she didn't stop, didn't dare to look away from Mitsuki's eyes, which had gone dark with desire.
Their eyes locked as Aya's hand reached the edge of Mitsuki's sports bra. She paused for a moment, unsure of what to do next. But Mitsuki's hand was firm, urging her on. With a shaky breath, Aya's fingertips grazed the soft fabric, feeling the heat of Mitsuki's skin through it. She could feel her girlfriend's heart pounding against her palm, a rhythm that matched her own.
Guitarist's eyes fluttered closed, and she leaned into the touch, her breath hitching. A soft whimper escaped her lips, and Aya felt her own body respond, her heart racing even faster. She couldn't believe this was happening, that she was touching Mitsuki like this. It was like a dream come true, but at the same time, it was terrifying.
Her hand moved on its own accord, tracing the contours of Mitsuki's body, exploring the dips and curves that she had only ever seen in passing glances. The feeling of Mitsuki's skin against hers was intoxicating, and Aya found herself leaning in, her breath mingling with Mitsuki's as she moved closer.
Their faces were inches apart now, and Aya could feel the heat radiating from Mitsuki's body. She was lost in the moment, lost in the sensation of finally being allowed to touch the person she had fantasized about for so long.
With a sudden burst of courage, Aya pushed Mitsuki down onto her bed, straddling her with a gentle force. Mitsuki's eyes widened in surprise, but she didn't resist, her hands coming up to cup Aya's face as Aya leaned in to kiss her. The kiss was soft at first, tentative, as if they were both still unsure of what was happening. But as Aya's hands began to wander over Mitsuki's body on her own, the passion grew.
Her fingers traced the line of Mitsuki's collarbone, feeling the rapid pulse beneath her fingertips. Aya's kiss grew bolder, more insistent, as if she was trying to devour her. Mitsuki's hands slid up Aya's back, gripping the fabric of her shirt as she pulled her closer, their kiss deepening.
Mitsuki's hands began to explore, too, moving under Aya's shirt, feeling the softness of her skin, the gentle curve of her waist. Aya gasped into the kiss as Mitsuki's thumbs brushed against the bare skin of her back, sending a shiver down her spine. The world outside their bubble faded away as their bodies moved in silent harmony, each touch a new discovery.
Aya's heart was racing, her mind a whirlwind of thoughts and sensations. She had never felt like this before, never knew that a simple touch could set her alight like this. She felt like she was drowning in Mitsuki's embrace, but it was a feeling she never wanted to escape from. The room was filled with the sound of their heavy breathing and the rustling of fabric as they explored each other's bodies.
Their bodies pressed together, the fabric of their clothes the only barrier left between them. Aya felt the muscles in Mitsuki's stomach tense as she touched her, and she was filled with a newfound sense of power. She had never felt like this before, never knew that she could make someone else feel so much with just her touch.
Mitsuki broke the kiss, panting, her eyes searching Aya's for any sign of doubt. "Can I take your shirt off?" she managed to ask, her voice hoarse with desire. Aya's eyes widened for a moment, then she nodded, a hint of a smile playing on her lips.
With a swift movement, Aya pulled her shirt over her head, revealing her bare chest. Mitsuki's eyes went wide, her face red, as she had to bite back a gasp. Aya wasn't wearing a bra. The sight of her pale, soft skin was like a punch to the gut, sending waves of desire crashing through Mitsuki's body.
Before Aya could react, Mitsuki's hands were on her waist, pushing her down onto the bed. The force was gentle but firm, leaving no room for argument. Aya's eyes grew even wider as she felt the weight of Mitsuki's body pressing her into the mattress, her hands pinning her wrists to the side. "Mitsuki?" she breathed, a mix of shock and excitement in her voice.
Mitsuki leaned in, her breath hot against Aya's neck. Aya felt a shiver run down her spine as Mitsuki's lips trailed kisses along her collarbone, her teeth grazing the sensitive skin. Her eyes fell closed, and she arched her back, offering herself up to the dark-haired girl's exploration.
The pink-haired beauty's hands found the hem of Mitsuki's shirt, her fingertips tracing the soft fabric. Mitsuki's eyes fluttered shut, a quiet whimper escaping her as Aya's nails scraped lightly against her stomach. She felt the cool air kiss her bare skin as Aya tugged the shirt up and over her head, revealing the plain white sports bra that had been hidden beneath. A soft click echoed through the room as Mitsuki deftly unclasped the bra, letting it fall away.
Their bodies were a tapestry of goosebumps and soft sighs as they felt each other's bare skin for the first time. Dark-haired girl's breath was hot on her girlfriend's neck as she kissed and licked her way down, her touch feather-light and reverent. Aya's eyes rolled back, her body arching, as Mitsuki's mouth found her hardened nipples. Each flick of her tongue sent a jolt of pleasure through Aya's core, and she couldn't help but let out a soft moan.
Mitsuki smirked against her skin, the sound of Aya's pleasure spurring her on. She took her time, savoring the taste and feel of her, her own body responding to the sweet sounds Aya was making. Her own breath grew ragged as she felt Aya's body tighten beneath her, the anticipation of what was to come building like a crescendo in her chest.
Aya's hands fisted in Mitsuki's dark hair, her back arching off the bed as guitarist's mouth continued to explore her body. The sensations were overwhelming, each touch sending a wave of pleasure crashing through her. She had never felt so exposed, so vulnerable, and yet it was the most amazing feeling in the world.
Mitsuki's hands slid down Aya's body, tracing the curve of her waist and the swell of her hips. She pulled down the skirt that had been riding up, revealing the lacy underwear that matched the color of Aya's eyes. The sight was almost too much to handle, and Mitsuki had to pause for a moment to catch her breath.
"Mitsuki..." Aya whispered, her voice trembling with need. "Please..."
"Are you sure?" Mitsuki murmured, her eyes meeting Aya's, searching for any hint of hesitation. Aya's nod was firm, her eyes pleading. With trembling hands, Mitsuki hooked her thumbs into the waistband of Aya's underwear, pulling it down slowly. Aya's legs fell apart, revealing herself completely to her girlfriend's gaze.
Mitsuki took in the sight of Aya, her cheeks flaming red. The sight of Aya's bare skin was like nothing she had ever seen before. She felt a rush of desire so intense it was almost painful. With a gentle touch, she traced the line of Aya's inner thigh, feeling the softness of her skin and the warmth that radiated from her core. Aya's body quivered beneath her, her breath coming in short gasps.
"Mitsuki," Aya whispered again, her voice barely above a moan. "I want you."
The words were all the encouragement Mitsuki needed. She leaned in, her mouth finding Aya's sensitive skin, her tongue tracing patterns that made her hips buck up. Her legs wrapped around Mitsuki's back, her fingers harshly tugging at black hair as the pleasure grew.
Mitsuki groaned against Aya's body, the grip on her hair sending a thrill down her spine. She never broke eye contact, the fire in Aya's gaze fueling her desire. Her hands moved upward, feeling the softness of Aya's stomach, the faint tremble of her ribs as she took a deep, shuddering breath. Her fingers found their way to pink-haired girl's breasts, tweaking the nipples in sync with the rhythm of her tongue.
Aya's eyes grew hazy with pleasure, her hips rocking in time with Mitsuki's ministrations. The sensation was like nothing she had ever felt before, the intimacy of the moment only heightening the intensity. The pressure building inside her was unbearable, a coil tightening with each flick of Mitsuki's tongue.
Mitsuki's thumbs stroked Aya's nipples, her own arousal growing with each gasp and whimper she pulled from her girlfriend's lips. The sound of Aya's breath hitching and her body tightening was like a siren's song, calling her deeper into the storm of passion. She felt Aya's legs tighten around her, her body arching as she reached the precipice.
With a final, fevered lick, Aya's eyes snapped shut, and she let out a cry that echoed through the room. Her body spasmed, a wave of pleasure crashing over her as she came, her nails digging into Mitsuki's back, leaving red marks. The guitarist felt her own body respond, her need growing with every tremor that passed through Aya's body.
As the aftershocks of Aya's climax subsided, Mitsuki quickly leaned in and hugged her, pulling her close. Her arms wrapped around Aya's back, her chin resting of top of her head. The sound of Aya's ragged breath and small whimpers a symphony to her ears. This was the aftercare they both needed, the gentle touch and closeness that followed the storm of passion.
Mitsuki felt Aya's body relax into her embrace, the tension leaving her muscles as she melted into the warmth of her girlfriend's arms. She kissed the top of Aya's head, her heart swelling with love and tenderness. They lay there, entwined on the bed, the only sounds in the room their mingled breaths and the faint thud of their hearts.
Aya's chest heaved as she tried to catch her breath, her cheeks flushed and eyes filled with a mix of embarrassment and satisfaction. She couldn't believe they had just crossed that line, but she also couldn't deny the feeling of closeness that now wrapped around them like a warm blanket. She lifted her head to look at Mitsuki, her eyes searching for any sign of regret or discomfort.
But what she saw was only pure love and desire reflected back at her, the same emotions that were currently coursing through her own veins. A soft smile tugged at Mitsuki's lips as she realized that Aya felt the same way.
The aftermath of their passionate encounter was a gentle symphony of tender whispers and soft kisses. Mitsuki's hands roamed over Aya's body, caressing her with a gentle touch that was in stark contrast to the passionate fervor of moments ago. Aya's cheeks were flushed, her eyes half-lidded and sparkling with a contentment she had never felt before.
They lay there, their hearts beating in sync, sharing the same rhythm that had just pounded through their bodies. Each touch was a silent promise, a vow to never let go, to explore this newfound intimacy and all the wonders it had to offer. They were no longer just high school sweethearts; they were something more profound, a secret shared between two souls.
