Sienna woke up to sunlight, streaming through floor-to-ceiling windows and the smell of coffee. For a disoriented moment, she forgot where she was. Then she felt the expensive sheets against her naked skin, saw Luca's penthouse around her, and remembered everything.
"Oh god." she sighed.
She had slept with Luca Marchetti. Multiple times. The second round was slower and more intense. The third had been in his shower at 2 AM, her back against the tiles while he'd made her come so hard that she saw stars.
"You're awake." Luca appeared in the doorway wearing nothing but low-slung pajama pants, holding two mugs of coffee. His hair was messy, and there were scratch marks on his chest from her nails.
He looked fucking edible.
"I should go," she said, even as her body protested the idea.
"Or you could drink this coffee and let me make you breakfast." He sat on the edge of the bed, handed her a mug. "I make excellent eggs."
"Hmhm, realty" she teased
"But Luca you know—"
"I know–I know." He tucked a strand of hair behind her ear. "This complicates things. But I don't regret it. Do you?"
"No," she admitted. "But I should."
"Why?"
She wanted to say, *Because I came here to destroy you. Because you're the enemy. Because I'm falling for you and that terrifies me.*
"Because mixing business and pleasure never ends well," she said instead.
"Then let's keep them separate. At the office, we're professional. But here—" His hand slid beneath the sheet, fingers tracing her inner thigh. "—here, you're mine."
Heat pooled between her legs. "That's not keeping them separate."
"No, but it's the best I can offer." His fingers moved higher, teasing. "Unless you want to stop this completely?"
"I—" Her breath hitched as he found her clit. "That's not fair."
"I never claimed to fight fair, *tesoro*." He pushed the sheet aside, eyes darkening as he took in her naked body in daylight. "God, you're gorgeous." he said, kissing all over her.
He set both coffee mugs aside and moved between her thighs. "Let me taste you properly. Like I promised."
Before she could respond, his mouth was on her, tongue sliding through her folds. Sienna's back arched off the bed, hands fisting in his hair.
Luca ate her like a man starving, alternating between long, slow licks and focused attention on her clit. When he pushed two fingers inside her, curling them just right, she came with a cry that probably woke his neighbors.
He didn't stop. Kept working her through pleasure until she was trembling, pushing at his head weakly.
"Too much," she gasped.
"One more," he said against her thigh. "Give me one more, baby."
His mouth returned to her clit, fingers pumping steadily, and impossibly, she felt another orgasm building. This one was different—deeper, more intense. When it hit, she sobbed his name, thighs clamping around his head.
Luca finally pulled back, looking incredibly satisfied with himself.
"Beautiful," he murmured. "You're so fucking beautiful when you cum."
She was still catching her breath when he crawled up her body, kissing her deeply. She could taste herself on his tongue.
"Your turn," she said, reaching for him.
But he caught her wrist, pinned it above her head. "Later. Right now, I want to fuck you while you're still sensitive. I want to still feel you clenching around me."
He was already reaching for a condom. Moments later, he was pushing inside her, and the stretch was almost too much on her oversensitive flesh.
"Luca," she whimpered.
"I know, baby. I know." He started moving, slow and deep. "You can take it. You can take all of me."
And she could. Her body adjusted, pleasure replacing the edge of discomfort. Soon she was moving with him, hips rising to meet his thrusts.
This was different from last night. Slower. More intimate. Luca's forehead pressed against hers, their breath mingling with locked eyes.
"You're ruining me," he said roughly. "I can't stop thinking about you. Can't focus on anything else."
"Good," she managed. "Because you're ruining me too."
He smiled and kissed her deeply as they moved together, building toward something that felt bigger than just physical release. When Sienna came this time, it was with Luca's name on her lips and his eyes locked on hers. He followed seconds later, groaning into her neck.
After lying tangled together, Luca's fingers traced patterns on her skin.
"Stay the weekend," he said.
"Oh please, what if we can't control it anymore—" she whined.
"I know it's crazy. I know we should slow down. But I don't want to." He propped himself up on one elbow, looking down at her. "Stay. Let me have you for two days where we don't think about work or complications. Just us."
"Okay," she heard herself say. "Fine, I'll stay."

The weekend passed in a blur of sex and conversation and moments of startling intimacy. Luca cooked for her—he hadn't been lying about the eggs. They watched old Italian films. He taught her a few words in Italian, laughing when she butchered the pronunciation.
They also fucked. A lot.
On the couch while a movie played in the background, Sienna rode him while he whispered filthy things in Italian. In the kitchen, she bent over the counter while he took her from behind. In bed, slow and sweet in the early morning light.
Sunday night, lying naked in his bed, Sienna's phone buzzed. A text from Marco: *Meeting tomorrow. Have information about Luca's vulnerabilities. A big opportunity is coming.*
Reality crashed back in.
"What is it?" Luca asked, noticing her tension.
She could lie. She should have lied, but something in his eyes made her tell the truth.
"Marco wants to meet. Says he has information about your vulnerabilities."
Luca went very still. "And you're going to meet with him?"
"That's my job. Remember?" She sat up, suddenly aware of how naked and vulnerable she was. "You hired me to find your thief. Marco hired me to spy on you. I'm playing both sides."
"I know." His hand slid up her spine. "I'm just reminding myself that when you betray me—because I know you will eventually—it's just….going to hurt like hell."
"Luca—"
"Don't." He pulled her back against his chest. "Don't make promises you can't keep. We both knew what this was."
But did they? Because somewhere between the first kiss and this moment, it had become something more than just physical. Something that scared Sienna more than any of Marco's threats.
"I should go home," she said quietly. "Get ready for tomorrow."
"Or you could stay one more night. Face tomorrow when it comes."
She turned in his arms, studied his face in the dim light. "Why are you doing this? You know I'm going to hurt you."
"Maybe I like the pain." He kissed her softly. "Or maybe I'm hoping you'll choose differently when the time comes."
"And if I don't?"
"Then at least I'll have had this, had you. Even if it was temporary."
Sienna kissed him, trying to pour everything she couldn't say into it. They made love again, slow and desperate, like they were trying to memorize each other.
Tomorrow she'd meet with Marco. Tomorrow she'd have to choose sides. Tomorrow everything will get more complicated.
But tonight, she let herself pretend that loving Luca Marchetti wasn't going to destroy them both.

Monday morning arrived too soon. Sienna dressed in Luca's bathroom, trying not to think about how domestic this felt. How right.
"I'll drive you to the office," Luca said, appearing behind her in the mirror. He was already in a suit, all business except for the way his hands settled on her hips.
"People will talk if we arrive together."
"Let them." He kissed her neck. "But you're right. Professional at the office. I'll have Marco pick you up."
The name hung between them like a threat.
"I can take the bu-–"
"It's fine, Sienna.
Do your job. I'll do mine." But his grip tightened slightly. "Just... be careful with him. I don't trust Marco."
"I know."
At the office, they maintained perfect professionalism. Sienna worked in her office, analyzing financial records. Luca was in meetings all morning. To anyone watching, they were just employers and employees.
But when their eyes met across the conference room during the afternoon briefing, the heat was unmistakable.
That night, Marco took her to dinner at an expensive restaurant.
"You're getting close to Luca," Marco said over wine. "I can tell."
"I'm doing my job."
"Good. Because I need you to do something for me." He slid a small device across the table. "Plant this in his office. It's a listening device. I need to know his plans."
Sienna stared at the bug. This was it. The moment where she had to choose.
"When?" she asked.
"Tomorrow. Can you do it?"
She thought about Luca's hands on her skin. His confession that she was ruining him. The way he looked at her like she was everything.
"Yes," she lied. "I can do it."
That night, she texted Luca: *We need to talk. Tomorrow. Your office.*
His response was immediate: *I'll be waiting.*
Sienna stared at the listening device on her nightstand and wondered if she was making the right choice.
Or if she was about to ruin everything for a man she was supposed to hate.
