The pool was almost silent, save for the soft hum of the filters. Tucked away beneath the City of London, this place was a hidden oasis; a brutalist cavern of polished concrete and sharp spotlights, arguably one of the last places where well-heeled city types could find a moment to call their own. Nate liked it for that very reason, especially for its anonymity. No office gossip, no idle chatter. Here, he could slip in and out without having to talk.

Nate was sick of talking. The last six months had been filled with it; negotiations with his ex-wife, endless meetings with lawyers, and worst of all, his family prying into the details of his divorce. He was over it. Swimming had become his escape from the world above; it grounded him, and pleasantly, he was now in the best shape of his life. But tonight, something was different.

Someone was watching him.

She sat at the far edge of the pool, her legs lazily kicking through the water. Younger than him by at least a decade, her skin, dark and smooth, gleamed under the spotlights; her black swimsuit clinging to her curves like a second skin. Nate paused, chest-deep in water, his eyes drawn to her, unable to look away. He didn’t know her; he hadn’t seen her before; and in a place as private as this, new faces stood out.

She knew he was watching; her body language made that clear. She shifted slightly, leaning back on her hands, arching her spine just enough to draw his attention to the shape of her body. She flicked her eyes towards him, braids hanging loose, her gaze piercing, assessing him, testing him.

Nate felt a shift inside him, a tightening in his chest.

Since his divorce, he’d been with a few women, but those encounters had been predictable, almost transactional; women in their forties, like him, seeking companionship through dinners and safe, polite sex. But this moment felt different. He suddenly felt his pulse quicken under the gaze of this stranger.

Nate dove beneath the surface, using the water to cool his thoughts. When he surfaced on the far side of the pool, he found her gaze still locked on him. She hadn’t looked away; she hadn’t moved.

There was no mistaking it now. Whoever she was, her gaze was an invitation meant for him.

Nate made the first move, wading slowly towards her, the water gently foaming in his wake. She didn’t flinch as he approached, her gaze remaining steady, as though this was all part of some unspoken plan. He stopped at the edge of the pool, standing just before her, regarding the milky light that danced across her figure.

“You’ve been watching me,” she said softly, her voice laced with the hint of an accent.

Nate felt a surge of adrenaline but kept his expression neutral. “I could say the same about you.”

Her lips curved. “Maybe.”

He didn’t smile back. Instead, his mouth softened into a smirk. There was something about this place, the anonymity of it all, that emboldened him. Without thinking, Nate moved beneath the water, brushing against her ankle, testing the moment. To his surprise, she didn’t pull away. Instead, she cocked her head slightly, her gaze never leaving his, as if to see how far he would go.

Nate’s hand slid higher, tracing the length of her calf, the sheen of her skin pricking the tips of his fingers. Her breath hitched, almost imperceptibly, but he caught it; she wanted this. His fingers moved further, skimming up her thigh, feeling the warmth of her body through the cool water.

“What’s your name?” Nate asked, his voice rougher than intended.

“Katerina,” she said, then paused, a smile playing on her lips. “But you can call me Kat.”

Nate’s hand moved higher still, his fingers grazing the edge of her swimsuit. “I’m Nate,” he offered, his hand tracing her leg. “And what can I do for you?”

Her eyes glinted, as she clicked her teeth softly. “You make me... curious.” She let her words hang between them.

Nate reached out, boldly brushing his fingers along her jawline, pulling her closer. His breath warm against her ear. “And what exactly are you curious about, Kat?”

He glanced around. The pool was empty now; it had been for some time. They were alone.

Kat tilted her head, bringing her lips close to his ear, her voice barely audible. “How far you’ll go. Right here. Right now.”

Kat took the lead, her long fingers curling around Nate’s arm as she slipped into the water. Her hand slid lower, brushing against his thigh, her fingers tracing the outline of his cock. Nate felt his breath catch in his throat.

Words felt unnecessary now. Nate’s hand instinctively slid around the back of her neck, his fingers tightening just enough for her to feel his control. Kat’s lips parted, but she didn’t pull away. Instead, Nate felt her surrender to his touch, her body softening, giving in.

Nate drew her deeper into the water, locking her gaze, searching for any hesitation. None came. Beneath the surface, his hands began to explore her body, parting her thighs as she pressed herself closer, her breath hot against his neck. Slowly Kat dropped her head against his shoulder, her body yielding to his control, her hips shifting to meet his hand.

“More,” Kat whispered, her voice hushed with need.

Nate obliged, parting the fabric of her swimsuit, slowly curving his fingers inside her, savouring the way her body tensed with pleasure. Kat moaned softly, her lips brushing against his neck as he stretched her open. Her breathing grew heavy; hands gripping his shoulders as she urged him on, her body pressing closer, as if to swallow his hand.

Nate’s cock throbbed against her thigh; the tension between them almost unbearable. He never wanted anyone more. He needed to be inside her; to fuck her; to taste her; but he was far from ready. He wanted to savour this moment, to draw it out; to watch her fall apart under his touch.

“Is this what you wanted?” Nate asked, his voice low, his breath hot against her ear.

Kat let out a low moan, her fingers digging into his shoulders as her hips rocked against his hand. “Yes,” she gasped, her lips now inches from his, her breath begging as his fingers filled her cunt. “Please.”

Nate’s grip tightened on the back of her neck as he quickened his pace, his hand moving faster, harder, her soft gasps rising to moans as she pressed her breasts against his chest, legs wrapping around his waist. He could feel her body tensing, her breathing erratic, her grip tightening as she teetered on the edge.

With a final thrust of his fingers, Kat shattered, her body convulsing as she came, her moans echoing softly in the vaulted pool. Nate held her, his hand still buried inside her as she trembled, her body clinging to his, her lips pressed against his neck.

As her climax subsided, Nate felt his control slipping. He’d never been the type to lose himself in the moment, but here, with her hips rocking gently against his hand everything felt different.

With one smooth movement, Nate pushed her against the edge of the pool, pressing her back against the cold tiles as he positioned himself between her legs. Kat’s breath came in shallow, quick bursts, her eyes now dark with anticipation.

Nate paused, the realisation of what they were about to do gripping his chest. He had never experienced this before; this reckless desire, this need to consume a stranger so utterly and totally. It made him feel alive in a way he hadn’t felt in years.

“Are you sure?” he asked, his voice quieter now, harder.

Kat’s hand slid up his chest, resting over his heart as she leaned forward, her lips grazing his neck. “Fuck me,” she whispered.

Nate’s hands slid down her sides, gripping her hips firmly. Without a word, he lifted her slightly, turning her in the water so that she faced the edge of the pool. Kat let out a soft gasp as her breasts pressed against the side, her back dropping into a low arch as he positioned her in front of him. She braced herself with her hands, the cool tiles slick against her palms.

She turned her head slightly, looking back at him, eyes wet with anticipation. “What are you waiting for?”

That was all it took.

With a low growl, Nate positioned himself behind her, his hands gripping her hips hard, pulling her back against him. He didn’t hesitate. He pushed his thick cock into her, filling her completely with one hard thrust. Kat moaned, her body jerking forward from the force of his thrust; her fingers gripping the edge of the pool tighter as he began to move, setting a rough, punishing pace.

Each thrust was harder than the last; feral; raw; the sound of their flesh echoing against the concrete walls. Nate’s hands slid up her back, his fingers tracing her spine, feeling her muscles tense and contract beneath his touch. He leaned forward, his breath hot against her ear as he slammed into her, his cock splitting her wider with every thrust.

“You like this?” he growled, his voice low and rough, barely more than a breath.

“Yes,” Kat gasped, her voice trembling. “Don’t stop.”

He didn’t plan to. Nate pulled her hips back harder, his fingers digging into her skin as he took her harder, faster, each movement shaping her body into a low submission. Kat’s body responded, her back arching, pushing herself further against him, moaning louder with each thrust.

Her moans turned into desperate, breathless cries as she approached the edge again, her entire body trembling as she fought to hold on. Nate could feel it, the way her body clenched around him, tightening with every thrust, the way her breath came in short, ragged gasps.

“Come for me,” he growled into her ear, his teeth grazing the soft skin of her neck. “I want to feel you come.”

Her fingers curled against the edge of the pool, her knuckles turning white as she lost control. With a sharp, shuddering cry, Kat’s body exploded into another orgasm, her legs shaking, her body convulsing as she came hard, her muscles contracting around him, pulling him deeper. Her moans filled the space, echoing off the walls, her voice raw, unrestrained.

But Nate didn’t stop. Even as her body quaked with pleasure, he kept going, thrusting harder, deeper, his own release building as he watched her fall apart beneath him. He was close, the tension coiling tight in his gut, his cock throbbing as her body squeezed him, urging him towards the edge.

Kat’s moans became soft, breathy whimpers, her body trembling as she gasped for breath, her fingers slipping against the wet tiles as she tried to steady herself. Nate was relentless, his hands gripping her hips tighter as he pounded into her, chasing his own release.

It hit him suddenly, like a wave crashing over him, unstoppable. With a low, guttural moan, Nate thrust deep inside her one last time, his body going rigid as he came, unloading into her, the pleasure ripping through him like fire. His hands clenched around her hips as his release pulsed through him, filling her completely.

For a long while, they stayed like that; pressed against each other, the water lapping gently around them. Nate could feel her breath against his neck, her body trembling slightly as her orgasm faded. His heart was pounding in his chest, his muscles aching, but he didn’t want to move.

Finally, Kat slowly loosened her grip around his waist, her legs sliding down his sides. She leaned back against the edge of the pool, her head resting against the tiles, her chest rising and falling with the effort of catching her breath.

Nate pulled back slightly, his hands still on her hips, his body still pulsing with the afterglow of what they’d just shared. He looked down at her, watching the way her lips resolved into a satisfied smile, her eyes half-lidded, her dark skin glistening.

“Well,” she murmured, her voice soft but teasing, “that answered my curiosity.”

Nate let out a low laugh, his hand brushing a damp braid away from her face. “I think,” he replied, his voice quiet, “this night isn’t over yet.”

Kat raised an eyebrow, her smile widening as she reached to run her fingers along his jaw. “Is that a promise?” she asked, her eyes darkening.

Nate smirked, leaning down to touch his lips against her ear. “It’s a guarantee.”
