The Billionaire’s Forbidden Obsession

Moonlight

Sebastian couldn't sleep.

It wasn't unusual, exactly, his mind rarely quieted enough for something as simple as rest, but tonight felt different, restless in a way that had nothing to do with mergers or boardrooms or the countdown to his mother's return. He'd tried the usual tricks. A drink he barely touched. A financial report he read three times without absorbing a single figure. Lying flat on his back in the dark, counting the hours until an alarm he didn't need would tell him it was acceptable to be awake.

None of it worked. His mind kept circling back to a kitchen counter and a woman who'd looked at him like his money meant nothing at all, which was, infuriatingly, the exact reason he couldn't stop thinking about her.

He gave up around midnight, pulled on a shirt he didn't bother buttoning, and went looking for the one thing that sometimes worked when nothing else did: the quiet of the rooftop pool, the city glittering below like it had somewhere better to be than watching him fail at being fine.

He didn't expect company.

He saw her before she saw him, a shape cutting through the water, unhurried, sure, moonlight scattering silver across the surface every time she moved. For a moment he simply stood in the doorway, frozen by something he didn't have a name for, watching the water slide off her shoulders as she surfaced, hair slicked back, throat tipped toward the sky like she was drinking in the night itself.

He should have said something. Should have announced himself, cleared his throat, done anything to keep this from becoming what it was already becoming.

He didn't move.

She swam the length of the pool once, twice, movements clean and unbothered, entirely unaware she had an audience, and God help him, he couldn't look away. The moonlight didn't just touch her, it seemed to choose her, tracing every line of her like it had been waiting all night for the chance. Water beaded on skin that looked carved rather than merely human, the curve of her shoulder, the arch of her back as she turned, the long stretch of her legs kicking lazily beneath the surface.

He'd seen beautiful women before. He'd built an entire life around being surrounded by them, curated and photographed and perfectly lit. None of them had ever looked like this, unposed, unaware, entirely herself, and somehow more devastating for it than anything he'd ever paid a stylist to produce.

She reached the shallow end and stood, water sluicing down her body as she pushed both hands back through her hair, and Sebastian forgot, briefly and completely, how to breathe.

Beyond sexy didn't begin to cover it. It felt like an insult to whatever this actually was, something closer to being struck, or drowning himself, standing perfectly dry on solid ground.

He must have made some sound, some shift of weight against the doorframe, because her head turned sharply toward him, eyes going wide in the dark.

"Sebastian." His name, not sir, not some careful distance she usually kept between them, just his name, startled out of her before she could stop it. She crossed her arms instinctively, though the water still covered most of her, chin lifting like she was daring him to comment. "I didn't realize anyone else was awake."

"Neither did I." His voice came out rougher than he intended. He couldn't seem to make himself look away, and he'd stopped, somewhere in the last thirty seconds, trying very hard to pretend he wasn't staring. "The pool's usually empty this late."

"I like it empty." A beat, then, quieter: "I like it when nobody's watching."

"I noticed." He hadn't meant to say it like that, low, almost rough, an admission dressed up as an observation. Something shifted in her expression, wariness and awareness tangled together, like she'd heard exactly what he hadn't said out loud.

For a long moment neither of them tried to fill the silence with anything safer. He was aware, distantly, that he should say something about the impropriety of it, the late hour, the fact that his girlfriend was almost certainly asleep somewhere across the city while he stood here memorizing the shape of another woman's collarbone. He was aware of all of it, and none of it moved him an inch closer to the door.

Neither of them moved for a long moment. The water lapped gently against the tiles. Somewhere below, the city hummed on, indifferent to the fact that Sebastian Cross, a man who did not lose his composure, who had built an empire on never once being caught off guard, currently couldn't remember a single reason he should look away from her.

"How long have you been standing there?" she asked, and there was something careful in the question now, like she was doing the same math he was, counting back through everything he might have seen.

"Long enough." He wasn't sure why he told her the truth. He rarely did, with anyone, about anything that mattered. "Not long enough to explain myself, apparently, since I'm still here."

"You could leave." She said it evenly, but she didn't move to cover herself further, didn't retreat toward the shallow end where the water might hide more of her. If anything, she straightened, chin lifting, meeting his stare with one of her own like she refused to be the only person in the moment who felt exposed.

"I could," he agreed. He still didn't leave.

"You're staring again."

"I'm aware."

A ghost of a smile crossed her face despite everything. "At least you're honest about it this time."

"You should go back to bed," she said finally, though she didn't sound entirely convinced of it herself.

"Probably." He didn't move.

"Sebastian."

"I know." And still, he stayed exactly where he was, watching moonlight turn her into something he had absolutely no business wanting as badly as he suddenly did, cataloguing the details he knew he shouldn't be cataloguing, the curve of her mouth, the water still clinging to her collarbone, the stubborn, unimpressed tilt of her chin even now, even soaking wet and caught somewhere she probably assumed she'd been alone.

This is a mistake, he told himself, the same warning he'd been repeating for weeks now, worn thin from overuse and doing absolutely nothing to move his feet.

"Goodnight, sir," she said pointedly, sliding back into deeper water, putting distance between them with visible effort.

He almost laughed. Almost told her that title had stopped meaning anything useful between them weeks ago, somewhere between ironed egos and midnight kitchens and now this, moonlight and water and a want so sharp it felt like something breaking open in his chest.

"Goodnight, Selena," he said instead, and made himself walk away before he did something he couldn't undo.

He didn't sleep that night either. But for entirely different reasons than before.

He lay in the dark long after, staring at a ceiling he couldn't see, replaying the exact moment she'd said his name instead of the title she usually hid behind. He'd built his entire adult life on control, on never wanting something badly enough to let it show on his face where a boardroom or a camera or his own mother might catch it. He'd been good at it. Great, even. It was possibly the only thing he'd ever been better at than his father.

And yet here he was, an hour past midnight, unsettled in a way he had no polite word for, thinking about the exact shade of moonlight on wet skin like a man half his age with none of his discipline.

He thought about Delphine, briefly, guiltily, and felt nothing shift in his chest at all. He thought about the will, about the merger, about every reason this particular want was not only inconvenient but actively dangerous, and felt those thoughts slide off him like water off the woman he couldn't stop picturing.

He thought about the way she'd lifted her chin at him instead of shrinking, and understood, with a kind of resigned clarity, that this wasn't going to go away simply because it should.

Sebastian Cross did not chase things. He acquired them, when he wanted them badly enough, cleanly and efficiently, the way he did everything else.

He had no idea, lying there in the dark, how he was supposed to acquire a woman who didn't want anything he could offer her, and wanted, with a low and unfamiliar ache, to find out exactly what it would take.

He must have slept eventually, because he woke to grey morning light and a phone full of messages he hadn't answered, his body heavy with the particular exhaustion of a night spent fighting himself rather than resting. He showered longer than usual, as if enough hot water might scrub the previous night into something he could file away and forget.

It didn't work. Nothing about her seemed inclined to be filed away and forgotten.

He found her in the kitchen by eight, exactly where he knew she'd be, and hated how much of his morning routine had quietly rearranged itself around the certainty of that fact. She glanced up as he entered, and something passed between them, quick and unspoken, an acknowledgment neither of them was ready to name out loud.

"Sir," she said, and there was the faintest edge of amusement in it now, like she knew exactly how strange the word sounded between them after last night.

"Selena." He said her name deliberately, watching for the flicker it caused, the same one he was fairly certain crossed his own face whenever she used his.

Neither of them mentioned the pool. There was nothing to mention, technically. Nothing had happened beyond two people standing too close to something they both knew better than to touch.

But he noticed, as he took his coffee from her hands that morning, that his fingers lingered half a second longer against hers than strictly necessary, and that she didn't pull away as quickly as she might have a week ago either.

It wasn't much. It was, he suspected, going to be everything.

He left for the office that morning more distracted than he'd been in years, and found himself, somewhere around his second meeting, smiling at nothing in particular, for no reason he was willing to explain to anyone who might ask.
