In Michael’s book, that put her solidly in the brainiac category, and an odd feeling ghosted up the back of his neck. Damned if he didn’t have a thing for smart girls. There was a reason why his favorite fantasy was Hot for Teacher. “I don’t know what that is.”

“I use statistics and calculus to model economic systems. Do you know how when you buy something online they usually email you with future recommendations? I help them formulate those recommendations. It’s a very fluid and fascinating field right now.” As she spoke, she leaned toward him, and her eyes lit with excitement. Her lips curved like she was telling him a secret. About math things. “Today’s material is completely different from what I used to teach when I was in graduate school.”

That odd feeling simmering up Michael’s spine increased in intensity. She’d somehow gotten prettier during the course of their discussion. Brown eyes and thick lashes, pouty lips, delicate jaw, vulnerable neck. Vivid images of him unfastening the buttons of her shirt flashed in his mind.

But unlike the usual, he didn’t want to do it quickly. He didn’t want to skip straight to the fucking, get out, and go home. This girl was different. It was that spark in her eyes. He wanted to take his time and see if he could make her shine with a different kind of excitement. His cock dug at the fly of his jeans, dragging Michael back to the here and now.

His skin had gone hot and sensitive, and his pulse thrummed with eagerness. He hadn’t been this turned on in forever. And he hadn’t been fantasizing she was someone else. He reminded himself this was business. His personal wants and needs didn’t play into this at all. This assignment was just like any other, and when it was done, he’d move on to the next.

He took a deep breath and said the first thing he could think of. “Were you on the math team in high school?”

She laughed down at her water. “No.”

“Science club? Maybe it was chess club.”

“No, and no.” Her smile was a sad, barely there thing that made him wonder what high school had been like for her. Looking back up at him, she said, “Let me guess, football quarterback.”

“Nope. My dad was a firm believer that sports are stupid.”

Her brow wrinkled with a little frown. “I find that difficult to believe. You’re very . . . athletic-looking.”

“He only encouraged practical things. Like self-defense.” He hated to agree with his dad on anything, but with the family business being what it was, and his helping out with it, the techniques had come in handy when shit kids teased him.

A discovering kind of smile lit her face. “What do you do? MMA? Kung fu? Jeet Kune Do?”

“I’ve done a little of everything. Why do you sound like you actually know what you’re talking about?”

Her gaze dropped back down to her water. “I like martial arts movies and things like that.”

He groaned as suspicion dawned. “Don’t tell me . . . you’re a Korean drama fan?”

She tilted her head as a smile peeked over her lips. “Yes.”

“I do not look like Daniel Henney.”

“No, you look better.”

He settled his hands on the edge of the table as his face heated. Fuck, he was blushing. What the hell kind of escort blushed? His sisters had posters of Henney plastered all over their bedroom walls, had even established a man-beauty scale of one to Henney. They’d agreed among themselves that Michael was a solid eight. He didn’t give a damn where he ranked, but it meant something that this genius girl gave him an eleven.

Their dinner arrived, saving him from having to respond to her compliment. She’d ordered the salmon, so he’d done the same. No way was he going to eat lamb. He snorted to himself. Woolly.

His fish was good, so he ate all of it. He suspected everything was good here. The Clement was one of Palo Alto’s most exclusive hotels with rooms going for more than a thousand dollars a night. Apparently, econometricians made shitloads of money.

As he watched Stella pick at her dinner, however, he noticed that everything about her was understated. Her face was devoid of makeup, her nails were short and unpainted, and her clothes were simple—though they fit her perfectly. They had to be custom made.

When she set her fork down and wiped her mouth, her salmon was only half finished. If they’d known each other better, he would have eaten it for her. His grandma always made him finish his dinner down to the last grain of rice.

“Is that all you’re going to eat?”

“I’m nervous,” she admitted.

“You don’t need to be.” He was a damned good escort, and he’d take care of her. Unlike most of his assignments, he even looked forward to it.

“I know. I can’t help it. Could we just get this over with?”

His eyebrows twitched. He’d never heard someone say something like that in reference to a night with him. Changing her mind-set was going to be fun.

“All right.” He draped his napkin over his empty dinner plate and got to his feet. “Let’s go to your room.”

Chapter 3

After Stella unlocked the door, she stepped into her intimately lit suite, set her purse on the chair by the door, and arranged her high heels against the wall, almost sighing as her bare feet flattened on the carpet.

Michael sent her an amused look, and she stared down at her toes. She’d taken her shoes off on autopilot. It was one of her routines. Was it rude to do that when you had company? Maybe she should put them back on. Her stomach knotted, and her heart raced at rabbit speed.

He took the decision out of her hands by kicking off his own black leather shoes and positioning them next to hers. When he finished, he shrugged out of his suit jacket and tossed it on the chair next to her purse, revealing the simple white T-shirt underneath. It stretched over his chest and upper arms, and his jeans rode low on narrow hips. Stella couldn’t help but stare.

His body was raw sculpted muscle and loose-limbed coordination. He was by far the finest male specimen she’d ever laid eyes on.

And they were going to have sex tonight.

She took a desperate breath and marched into the bathroom, where she braced her hands on the cool granite and stared at her reflection in the mirror. Her eyes were open a fraction too wide, and her face was paper pale, her lips dry. She didn’t think she could go through with this. She shouldn’t have picked such a good-looking escort. What had she been thinking?

Her lips twisted with a grimace. She hadn’t been thinking. After perusing the escort files for hours, sifting through countless faces and descriptions that had blurred together, she’d taken one look at Michael and known he was the one. It’d been his eyes. Dark brown with slashing eyebrows above, they looked intense . . . but kind. All of his five-star reviews had only cemented her decision. Looking like the hottest K-drama star ever didn’t hurt, either. Well, except for now, that was. There was a good chance she might throw up her dinner into the sink.

Through the mirror, she saw him step into the doorway and lean against the jamb. That motion alone was so sexy, she felt her heart trip, stumble, and scramble to continue beating. He walked into the bathroom and stopped behind her, his eyes locked on hers in the mirror. When she wasn’t wearing her heels, he was more than half a foot taller than her. She wasn’t sure if she liked feeling this small.

“Can I take your hair down?” he asked.

She nodded once. Within seconds, the tension on her scalp released, and her hair tumbled free. Her black hairband landed on the countertop before he eased his fingers into her hair, separating the tendrils so they fell to her shoulders and down her back. She vibrated with tension as she waited for him to initiate intimacy and send her body into nervous lockdown. It was going to happen, and then he’d see what he was working with.

A black imperfection on his bicep caught her eye, and she turned around to inspect it closer. She lifted a hand to touch it but stopped before making contact. She never touched people without permission. “What is this?”

His lips curved with a slow, crooked grin, showing off perfect white teeth. “My tattoo.”

Her throat worked on an involuntary swallow, and a wave of heat swept over her. She’d never seen the point of tattoos. Until now. Michael with a tattoo was just about the hottest thing she could imagine.
