That night, Sienna barely slept. Every time she closed her eyes, she felt Luca's mouth on hers, his hand on her neck, the promise in his voice, *I'm going to fuck you.*
She arrived at Marchetti Tower at 8 AM, determined to be professional. To remember why she was here.
That lasted exactly for three hours.
"My office. Now." Luca's voice came through her phone at eleven.
When she walked in, he was standing by the windows, jacket off, sleeves rolled up. The sight of his forearms so strong, veined, dusted with dark hair which shouldn't have been erotic. But it was.
"Close the door," he said without turning around.
She did. The click of the lock sounded loud in the quiet office.
"We need to talk about last night," he said.
"Okay."
He finally turned to face her, and the heat in his eyes nearly buckled her knees.
"I don't mix business with pleasure," he said. "It's a rule I've never broken."
"Then why did you kiss me?"
"Because you make me want to break every fucking rule I have." He crossed to her in three strides. "Tell me you don't feel this. Tell me I'm imagining it."
"You're not imagining it, I feel it too." Sienna said calmly.
"Then we have a problem." His hand came up, fingers tracing her jawline. "Because I want you, Sienna. I want you so badly I'm losing focus. And in my world, losing focus gets people killed."
"So what do we do?"
"We have two options." His thumb brushed her bottom lip. "Option one: we stay professional. Pretend last night didn't happen. You do your job, I do mine."
"And option two?"
"Option two…" He leaned in, lips barely brushing her ear. "we get this out of our system, just at once. Then we go back to being professional."
Her laugh was shaky. "You think one time will be enough?"
"No. But I'm trying to be logical here."
"Since when is anything between us logical?"
"Fair point." He pulled back enough to look at her. "So what's it going to be?"
She should choose option one, to walk away, maintain boundaries and remember her mission.
"Option two," she whispered.
The last thread of Luca's control snapped.
He kissed her hard, backing her against the door, one hand fisting in her hair while the other gripped her hip. Sienna moaned into his mouth, arching against him, so desperate for more contact.
"Tell me to stop," he growled against her lips.
"Don't you dare stop..."
His hands found the zipper of her skirt, dragging it down. The fabric pooled at her feet. He lifted her easily as she wrapped her legs around his waist, feeling the hard length of him pressing against her through his pants.
"Fuck, you feel good," he muttered, carrying her to his desk. He set her down, swept everything aside with one arm.
Papers scattered, his laptop hit the floor but neither of them cared.
Luca's mouth was on her throat, sucking hard enough to mark. His hands pushed her blouse up, and found the lace of her bra.
"This is nice," he said, tracing the edge. "But it's in my way."
He unhooked it with practiced ease, pushed both blouse and bra up until her breasts were exposed. For a moment, he just looked at her, eyes dark with pleasurable hunger.
"Bellissima," he murmured. Then his mouth was on her, tongue circling one nipple while his fingers worked the other.
Sienna's head fell back, fingers tangling in his hair. Every nerve ending was on fire. When his teeth grazed her sensitive flesh, she gasped his name.
"That's it," he encouraged. "But I can't hear you."
His hand slid between her thighs, fingers finding her through the thin silk of her panties. She was already soaked, and they both knew it.
"So wet for me," he said, voice rough. "How long have you been like this?"
"Since last night, Since you kissed me."
"Good." He pushed her panties aside, fingers sliding through her folds. "Because it's been hard since the moment you walked into my office three weeks ago."
He pushed two fingers inside her, and Sienna cried out at the intrusion. It had been so long, and he was so thick, stretching her.
"Too much?" he asked, stilling.
"Not enough," she gasped. "More please Luca, more…."
He added a third finger, his thumb found her clit within seconds, he worked her with overwhelming precision. His other hand was still on her breast, pinching and rolling her nipple. The dual sensation was just… something else.
"Look at me," he commanded.
She forced her eyes open, met his gaze. The intensity there—the hunger, the possessiveness—pushed her closer to the edge.
"That's it," he murmured. "I want to watch you come, want to see what you look like when you fall apart." he smiled.
His fingers curled inside her, hitting that perfect spot, and Sienna shattered. The orgasm crashed through her, so intense she saw stars. Luca swallowed her cries with his mouth, fingers working her through every wave.
When she finally came down, trembling and breathless, he slowly withdrew his fingers. Maintained eye contact as he brought them to his mouth, tasting her.
"Delizioso," he said. "I'm going to taste you properly next time. Spend hours between your thighs until you're begging me to stop." he said promisingly.
"Next time?" she managed. "I thought this was only one time."
"I lied." He kissed her again, softer this time. "I want you in my bed, Sienna. I want to hear you scream my name. Want to fuck you until neither of us can walk straight."
She should say no, she has to..right?
She should remember this was her enemy, the man she came to destroy.
Instead, she reached for his belt.
"Then take me to bed," she said.
His answering smile was pure sin. "My place or yours?"
"Yours. I want to see where the devil sleeps."
"Careful, *tesoro*. You might not wanna leave."
He helped her straighten her clothes, though his hands lingered possessively. When they were both presentable—barely, he grabbed his jacket.
"Marco can handle things this afternoon," he said. "I'm taking the rest of the day off."
"You never take time off?"
"I will do it for you."
The drive to his penthouse took twenty minutes. Twenty minutes of Luca's hand on her thigh, inching higher, while she tried not to squirm. By the time they reached his building, she was ready to combust.
The elevator ride to the top floor was torture. Luca crowded her against the wall, kissing her breathless, one hand up her skirt.
"I can't wait," he muttered against her mouth. "I need to be inside you."
"Then hurry."
The doors opened directly into his penthouse. Sienna had a vague impression of modern luxury before Luca was backing her toward the bedroom, shedding his jacket, loosening his tie.
She reached his bedroom, a massive bed, floor-to-ceiling windows overlooking the city… "wow" her jaws dropped.
She turned, "How do you want me?" she asked.
His eyes went molten. "Every way possible. But for now–" He advanced on her slowly, "on your back, legs spread. I want to see everything when I fuck you."
Heat flooded through her at his words. She pulled her blouse over her head, unhooked her bra, let them fall. Stepped out of her skirt. Until she was standing in just her heels and ruined panties.
Luca's gaze raked over her like a physical touch. "Leave the heels on."
He stripped efficiently, and Sienna's breath caught. His body was even better than she'd imagined—all lean muscle and golden skin, with scars that told stories she wanted to learn.
And his cock—thick and hard as perfect.
He rolled on a condom with practiced ease, then prowled toward her like a predator.
"Last chance to change your mind," he said.
"Shut up and fuck me, Marchetti." she commanded.
He pushed her onto the bed, spread her thighs, and in one smooth thrust, buried himself inside her.
They both groaned. Sienna at the fullness, the stretch, the perfection of it. Luca at the tight, wet heat surrounding him.
"Dio," he breathed. "You feel incredible."
"Move," she demanded. "Please, Luca, move."
He did, pulling almost all the way out before slamming back in. Set a punishing pace that had her gasping, nails raking down his back.
"Is this what you wanted?" he growled. "Me fucking you?"
"Yes! God, yes!" Sienna screamed.
He shifted the angle, hitting deeper as Sienna cried out. Her second orgasm was building fast, coiling tight in her belly.
"Touch yourself," he ordered. "Make yourself cum on my cock."
She obeyed, fingers finding her clit, circling desperately. The combination of his thrusts and her own touch pushed her over the edge. She came with a scream, clenching around him.
Luca cursed in Italian, thrusts becoming erratic. Then he was coming too, spilling inside her with a groan that sounded like her name.
After, they lay tangled together, sweaty and satisfied. Luca's hand traced lazy patterns on her skin.
"So much for one time," she laughed.
"So much for one time," he agreed. "Stay tonight."
"Luca—"
"Stay. Let me cook you dinner ...have you in bed, then tomorrow we can go back to being complicated. But tonight, just–stay, please"
She should say no. Should have left before this gets more tangled.
"Okay," she whispered instead. "I'll stay."
And as he pulled her closer, Sienna wondered if she was making the biggest mistake of her life.
Or the best decision.
