Chapter Text
In the brightly lit women's section of the inn's public bath, Suzu sat submerged up to her neck in steaming water, trying desperately not to stare at Shino and Aria as they chatted idly about their day at the beach. Aria's words from earlier echoed in Suzu's mind: "You know there's a mixed bathing section too?"
She had stumbled upon her parents having sex a few times, but it never stirred anything within her except mild annoyance that they didn't close their door properly. Yet now, she felt an odd curiosity stirring within her, unlike anything she'd experienced before — something that made her heart beat faster and her cheeks flush slightly pinker than the bath's heat could account for.
I wonder what mixed bathing is like...
With a casualness that belied the turmoil inside her, Suzu excused herself and slipped out of their bath, leaving Shino and Aria chatting obliviously behind her. The mixed bathing area was separated from theirs by only a flimsy sliding door that creaked softly when it slid open. The air here felt different — heavier with anticipation or perhaps just steam.
The mixed section was larger than the one reserved for females alone. A single couple occupied one corner, hidden mostly but not entirely by the rock formations meant to provide privacy in this otherwise communal space. Their bodies pressed close as they whispered to one another, they were trying so hard to be discreet, yet there was no mistaking what they were doing. Suzu's breath hitched in her throat at the sight. She had never seen anything like it before; not up close anyway. Her cheeks flushed hotter than any bath water could manage.
Suzu's breath hitched as she watched the man reach between his lover's legs, stroking her with a familiarity that sent waves of heat coursing through Suzu herself. She felt an unfamiliar ache in her own core and unconsciously began to rub her thighs together under the water trying to alleviate some unseen pressure building inside.
What am I doing? Her thoughts were racing now, but so was her heart — pounding like thunder against her eardrums as she watched their bodies move together with increasing urgency...
Suddenly, a voice cut through Suzu's haze: "Suzu? What are you—"
She turned sharply only for her breath to hitch as she found Tsuda standing there — he'd clearly come from the direction of the men's side, his eyes wide in surprise, and something else... was that excitement?
Suzu waved him over urgently and grabbed him by the wrist — her small hand barely wrapping halfway around his arm. She pulled him behind the rock, pressing a finger against his lips when he opened his mouth to speak again.
"I-I didn't want them to notice!" Suzu quietly stammered out. But I don't know if that's the whole truth...
She pointed towards where she'd been watching earlier. Tsuda peeked around the edge of their hiding spot just as the couple began moving more explicitly together — too caught up in each other's arms to notice they had an audience now.
Suzu peeked back around their hiding spot, watching as the couple continued their dance of desire under cover of steam. She felt herself growing warmer again — not just from the heat of the bathwater or even embarrassment at being caught spying on others' intimacy.
This feels... good, she realized with a jolt, watching them like this makes me feel all tingly inside.
Her hand moved without conscious thought back down between her legs. She tried to fight it — really did! However, the sight of those two bodies moving together was too much for young Suzu's untrained mind and hormones.
Tsuda noticed what she was doing almost immediately, his breath catching audibly in response as he watched her slender fingers move beneath the water with increasing urgency. He felt himself growing hard at just how innocent yet erotic this scene unfolding before him truly was — a girl masturbating openly while watching another couple intimacy mere feet away.
I should stop her, Tsuda thought, but...
But he didn't want to interrupt whatever it was that had taken hold of Suzu. Instead, his own hand moved downwards until it found its way around himself, stroking slowly as he watched the scene unfold before him like some sort of perverted voyeur.
Suzu's breathing grew ragged now; her eyes locked onto where those two bodies joined together in a dance older than time itself. She could feel something building inside herself — an intense pressure that threatened to consume every fiber of her being if left unchecked...
And then, without warning or preamble whatsoever:
Oh!
Her body convulsed as waves upon waves of pleasure crashed over and through her like some sort of tidal force unleashed from within.
Tsuda watched in awe at the sight before him — Suzu's small frame shaking uncontrollably while she bit down hard on one knuckle to muffle any sounds escaping past those sweet lips. Her eyes were squeezed shut, tears leaking out onto flushed cheeks as her orgasm tore through every nerve ending like wildfire.
It was beautiful; it was obscene... and Tsuda couldn't look away even if he wanted to now that the floodgates had been opened within him too...
He stepped closer behind Suzu — close enough for his cockhead to brush against one rounded cheek. She gasped softly, eyes flying open as she realized what pressed so insistently at her backside.
"Tsuda...?" Her voice was barely above a whisper yet it echoed loudly in the otherwise silent bathhouse around them now that the couple had finished their act and slipped away...
But before he could answer, Suzu reached behind herself — those small fingers wrapping tightly around his shaft. She guided him towards her entrance without hesitation or shame.
She wants this, Tsuda realized with a jolt of surprise mixed heavily with lustful excitement coursing through every vein in his body now too... And so do I.
He pushed forward slowly, feeling Suzu's tightness envelop and squeeze around the head of his cock. She gasped again — louder than before but still quiet enough not to draw unwanted attention from anyone else who might be lurking nearby.
Tsuda began moving within her then; slow thrusts that grew steadily faster as they both found their rhythm together in this dance just like that couple had done earlier tonight...
Suzu felt every inch of him sliding back and forth inside herself, igniting sparks along each nerve ending until she thought surely there must be some sort of fire burning brightly within her core now too. Her fingers clawed at the rock they hid behind while Tsuda's hands gripped tightly onto those slim hips — pulling them backward to meet his thrusts with increasing urgency.
Their bodies slapped together loudly, echoing through their little hideaway like a symphony composed solely for two lovers entwined in passion under cover of darkness and steam...
Suzu felt another orgasm building within her core; this one was even more intense than the first had been. She bit down hard on that same knuckle again as she tried desperately to keep quiet while waves upon waves crashed over and through every fiber of her being once more.
Tsuda could feel it too — how close they both were now... He reached around the front, finding Suzu's clit with ease before rubbing furiously against the sensitive nubbin. That was all it took for them both to tumble headlong into oblivion together...
Oh!
Their cries echoed through their little hideaway as one; a symphony of pleasure sung out loud and clear by two young lovers lost in each other's arms under cover of darkness, steam...and the lingering scent of sex that hung heavy in the air around them now.
Tsuda collapsed against Suzu then — his body spent completely after pouring every last drop into her waiting depths. They stayed like this for several long moments; breaths ragged and hearts pounding wildly as they came down from their shared high together...
Finally, Tsuda pulled out slowly before wrapping an arm protectively around Suzu's shoulders.
"Come on," he whispered softly against one ear lobe, "let's get back to our room. I think we've had enough excitement for tonight."
Suzu nodded silently in agreement — too exhausted and sated even to speak now as they made their way hand-in-hand through the darkened corridors of the inn towards where Shino and Aria awaited them unaware...
