Work Text:
The community pool was technically closed – had been for the last hour. But Valentina had a key, courtesy of her summer job as a lifeguard. She'd come back after her shift for some solo swimming, enjoying the rare luxury of having the entire pool to herself.
Or so she'd thought.
She surfaced from an underwater lap to find someone else in the pool. Not just someone – him.
Theo fucking Martinez.
He was in the shallow end, water barely reaching his waist, arms spread along the pool's edge. Even in the dim lighting from the underwater pool lights, she could see his infuriating smirk.
"Breaking and entering, Martinez?" Valentina called out, treading water.
"I could ask you the same thing, Torres. Although I'm guessing you have a key." He pushed off from the wall, moving toward her with lazy, confident strokes.
"I work here. What's your excuse?"
"Couldn't sleep. Figured a swim might help." He stopped a few feet away, close enough that she could see the water droplets sliding down his chest. "Didn't expect company."
"Unwelcome company," Valentina corrected, though she didn't move away.
They'd been rivals since freshman year of college – competing for the same internship, the same scholarships, the same positions in student government. Everything was a competition between them, every interaction charged with barely concealed hostility.
And lately, something else.
"You could leave," Theo suggested, moving fractionally closer.
"Why should I? I was here first."
"Technically, the pool is closed. We're both trespassing."
"I have permission."
"Prove it."
Valentina's eyes narrowed. "What's your game, Martinez?"
"No game." But his eyes said otherwise as they traveled down what he could see of her body through the water – her red one-piece suit that she wore for lifeguarding, functional but fitted. "Just enjoying the water."
"Race you," Valentina said suddenly, the words out before she'd fully thought them through.
Theo's eyebrow raised. "What?"
"You heard me. One lap. Freestyle. Unless you're afraid you'll lose."
His smirk widened. "What are the stakes?"
"If I win, you leave. If you win..." She hesitated.
"If I win, I stay. And you stop pretending you hate me."
The words hung in the air between them, heavy with implication.
"I'm not pretending," Valentina said, but her voice lacked conviction.
"Liar." Theo moved closer, close enough now that she could feel the water displacement from his movement. "I've seen how you look at me when you think I'm not watching."
"You're delusional."
"Prove it. Race me."
They moved to the deep end, positioning themselves at the wall. The pool was Olympic-length, so one lap meant there and back.
"On three," Valentina said. "One. Two. Three."
They pushed off simultaneously, their competitive natures taking over. Valentina was a strong swimmer – years of lessons and regular practice. But Theo was on the university swim team, and he pulled ahead quickly.
She pushed harder, her arms cutting through the water, her legs kicking furiously. They touched the far wall within a second of each other, turned, and powered back.
Theo touched first. Barely.
Valentina surfaced, breathing hard, and found him already there, waiting. He wasn't even winded.
"You cheated," she accused, though she knew he hadn't.
"I won fair and square. Which means..." He moved closer, backing her against the pool wall. "You stop pretending."
"Pretending what?"
"That you don't want this."
His hands came to rest on either side of her on the pool's edge, caging her in. The water made their bodies buoyant, bringing them closer with each small movement.
"This is insane," Valentina breathed, but she didn't push him away.
"Probably. But I'm tired of fighting it. Aren't you?"
She was. God, she was so tired of pretending every argument, every sharp word, wasn't just cover for what she really wanted.
"If we do this," she said quietly, "it doesn't change anything. We're still rivals."
"Obviously." His face was inches from hers now. "I still plan to destroy you in the internship competition."
"Over my dead body."
"God, you're hot when you're competitive."
Then his mouth was on hers, and thinking became impossible.
The kiss was aggressive from the start – teeth and tongue, biting and claiming. Years of tension exploding in a single moment. Valentina's arms wrapped around his neck, her legs automatically wrapping around his waist.
Theo groaned into her mouth, his hands gripping her hips, pulling her tighter against him. She could feel his erection pressing against her through their swimsuits, hard and insistent.
"We can't," she gasped when they broke for air. "Not here. Someone could—"
"The pool is closed. Security doesn't patrol for another hour." His mouth moved to her neck, biting and sucking. "And the underwater lights make it hard to see details from outside."
His hand slid up her torso, finding her breast through the suit's material. Her nipple was already hard, visible through the fabric, and he rubbed his thumb over it deliberately.
"Fuck," Valentina moaned, her head falling back against the pool's edge.
"Tell me to stop," Theo challenged, his other hand sliding down between their bodies. "Tell me you don't want this."
"I hate you," she said instead, but her hips rolled against him.
"I know." His fingers found the edge of her swimsuit bottom, slipping underneath. "The feeling's mutual."
His fingers slid through her folds, finding her slick even in the water. "So wet for me," he murmured against her ear. "Is this what you think about when we argue? How it would feel if I touched you?"
"Shut up," Valentina gasped, but she couldn't deny it – couldn't deny that every heated debate had ended with her alone in her room, hand between her legs, imagining exactly this.
Theo circled her clit with practiced ease, and her hips bucked against his hand. The water made the friction different – softer, stranger – but no less effective.
"We should go somewhere private," she managed, even as her body betrayed her by pressing closer.
"Where's the fun in that?" He slid two fingers inside her, and her moan echoed across the empty pool. "I like you like this. Desperate. At my mercy."
"I'm not—" But her protest died as he curved his fingers, finding that spot inside her that made her see stars.
His other hand pulled down the top of her swimsuit, freeing her breasts. The air was cool on her wet skin, making her nipples tighten further. He lowered his head, taking one into his mouth.
"Oh God," Valentina whimpered, one hand fisting in his hair. "Someone could see."
"Then you better stay quiet."
His fingers moved faster, his thumb finding her clit while his mouth worked her breast. The combination of sensations was overwhelming – the water, his mouth, his fingers, the ever-present risk of discovery.
"Theo," she gasped, her thighs starting to shake around his waist. "I'm going to—"
"Not yet." He pulled his hand away, and she made a sound of frustration that made him laugh. "My turn first."
He lifted her slightly, positioning her on the pool's edge so she was sitting on the concrete, legs dangling in the water. Before she could process what he was doing, he'd pulled her swimsuit bottom to the side and buried his face between her thighs.
"Fuck!" The word came out louder than intended, echoing across the pool area. She clapped a hand over her mouth, eyes darting around for any sign of security or late-night swimmers.
But Theo was merciless, his tongue working her clit with the same competitive precision he brought to everything else. His hands gripped her thighs, spreading them wider, keeping her exactly where he wanted her.
The concrete was hard and rough against her ass, the night air cool on her exposed skin, but all she could focus on was his mouth. He alternated between broad strokes of his tongue and focused attention on her clit, occasionally dipping down to thrust his tongue inside her.
"You taste incredible," he groaned against her, the vibration making her hips buck.
Her hand tangled in his wet hair, holding him against her. She should stop this – should push him away and leave before they got caught. But she couldn't. She was too far gone, too desperate for release.
He added two fingers while his tongue continued its assault, and the dual stimulation was too much. Her orgasm built rapidly, tension coiling in her belly.
"Theo, I'm—" She couldn't finish the sentence, couldn't warn him before it crashed over her.
She came with a strangled cry, her thighs clamping around his head, her whole body shaking. He worked her through it, his fingers and tongue not stopping until she pushed weakly at his head.
"Too much," she gasped.
He pulled back, his face glistening with her arousal, looking impossibly smug. "Still hate me?"
"More than ever," she managed, though the words lacked heat.
"Good." He pulled her back into the water, spinning her around so her back was to his chest, her hands braced against the pool's edge. "Because I'm not done with you yet."
She felt him adjust their positions, felt the hard length of him pressing against her entrance through their suits. "We don't have—"
"Front pocket of my swim trunks. Left side."
She reached back, finding the small waterproof pouch with condoms inside. "You came prepared."
"Hoped for the best, planned for everything." He took one from her, and she heard the wrapper tearing. "Now push that suit aside for me."
Valentina hesitated for only a second before complying, pulling the fabric aside. She felt him position himself, the head of his cock pressing against her entrance.
"Last chance to back out," he murmured against her ear.
"Fuck you, Martinez."
"That's the idea, Torres."
He pushed inside slowly, and they both groaned. The water made the entry different – stranger friction, different sensations – but he filled her completely.
"So fucking tight," he groaned, giving her a moment to adjust before starting to move.
His thrusts were controlled at first, measured, but quickly became more desperate. One hand gripped her hip while the other reached around to find her clit, rubbing circles that matched his rhythm.
The pool water sloshed with their movements, small waves hitting the edge and splashing back. Anyone who walked by would definitely know what was happening, but Valentina couldn't bring herself to care anymore.
"Harder," she demanded, pushing back against him.
"So demanding." But he complied, his hips snapping forward with more force.
The sound of their bodies meeting, the slosh of water, their combined breathing and moans – it filled the enclosed pool area. Valentina braced herself better against the wall, taking him deeper with each thrust.
"I've imagined this," Theo admitted roughly, his voice strained. "Every time you argued with me in class. Every debate. Every fucking time you rolled your eyes at me. I imagined shutting you up exactly like this."
"That's—oh God—that's incredibly arrogant," Valentina gasped.
"And you've imagined it too. Don't lie."
She couldn't. It was too accurate. Every heated argument had ended with her aroused and frustrated in equal measure.
His fingers on her clit became more insistent, his thrusts harder and deeper. She could feel another orgasm building, faster and more intense than the first.
"Come on my cock," Theo commanded. "I want to feel you fall apart."
The words pushed her over the edge. Her second orgasm was somehow more intense than the first, her walls clenching around him rhythmically, her arms nearly giving out from the intensity.
Theo groaned, his rhythm faltering. "Fuck, Valentina, I'm—"
He thrust deep one final time and came, his entire body tensing against her back, her name falling from his lips like a prayer and a curse combined.
They stayed locked together for a long moment, both breathing hard, neither quite ready to move. Finally, Theo withdrew carefully and dealt with the condom.
Valentina adjusted her swimsuit, suddenly hyper-aware of what they'd just done. In public. At her workplace.
"That was—" she started.
"Insane?" Theo supplied.
"I was going to say 'a massive mistake.'"
"Liar." But his voice was gentler now. He turned her to face him, his hands cupping her face. "We can pretend this never happened, if that's what you want."
Did she want that? Part of her screamed yes – this complicated everything. But a larger part couldn't regret it.
"We're still competing for that internship," she said instead.
"Obviously."
"And I'm still going to beat you."
"You can try."
They stared at each other for a moment, then both started laughing – quiet, slightly hysterical laughter that acknowledged the absurdity of their situation.
"We should get out of here before security actually does show up," Valentina said finally.
"Probably wise."
They swam to the shallow end and climbed out, grabbing their towels from where they'd left them. As they dried off, the tension between them had shifted – still present, but different now. Charged with possibility rather than just conflict.
"Same time tomorrow?" Theo asked as they walked toward the exit.
Valentina paused, key in hand. "You're impossible."
"That's not a no."
It wasn't. And they both knew it.
"Don't be late, Martinez."
His answering smile was brilliant. "Wouldn't dream of it, Torres."
