Setup: This is a scene when Marin was in college and overhears some dirty talk when she’s working late at the university.Holy. Shit. Marin pressed her lips together. Obviously two other people thought they were alone, too. Had students snuck into the building to get it on? Or maybe it was one of the professors. Oh, God, please don’t let it be a professor. She should turn around right now and go back to Professor Roberts’s office. Last thing she needed was to see one of her teachers in some compromising position. She would die of mortification.

But instead of backing up, she found herself tilting her head to isolate where the voice was coming from, and her feet moved forward a few steps.

“Yeah, you like that. I know. I bet you’re wet for me right now just thinking about how it would feel. Maybe I should check. Keep your hands against the wall.”

A hot shiver zipped through Marin, making every part of her hyperaware. .

“I’m so hard for you. Can you feel how much I want you?” That voice was like velvet against Marin’s skin. She closed her eyes, imagining the picture the stranger was painting—some hot guy behind her, pinning her to the wall, his erection rubbing against her. She’d never been in that situation, but her body sure knew how to react to the idea. Her hand drifted up to her neck and pressed against her throat, her pulse beating like hummingbird wings beneath her fingertips.

She waited with held breath to hear the woman’s response, but no voice answered the man’s question. Can you feel how much I want you? he’d asked. And hell if Marin wasn’t dying to know. She strained to hear.

“I tug your panties off and trail my hand up your thighs until I can feel your hot, slick . . .”

Marin braced her other hand against the wall and leaned so far forward that one more inch would’ve sent her toppling over. Your hot . . .

“Goddammit. Motherf**ker.”

The curse snapped Marin out of the spell she’d fallen into, and she straightened instantly, her face hot and her heartbeat pounding in places it shouldn’t be. There was a groaning squeak of an office chair and another slew of colorful swearing.

Whoever had been saying the dirty things had changed his tone of voice and now sounded ten kinds of annoyed. A wadded-up ball of paper came flying out of an open doorway a few yards down. She followed the arc and watched the paper land on the floor. Only then did she notice there were three others like it already littering the hallway.

Lamplight shifted on the pale linoleum as if the person inside the office was moving around, and Marin flattened herself against the wall, trying to make herself one with it. Please don’t come out. Please don’t come out. The silent prayer whispered through her as she counted the doors between her and the mystery voice, mentally labeling each one. When she realized it was one of the offices they let the Ph.D. students use and not a professor’s, she let out a breath.

Either way, she had no intention of alerting her hall mate that he wasn’t alone. But at least she could stop worrying she’d gotten all fevered over one of her professors. Now she just had to figure out how to get past the damn door without letting him see her. She’d gotten used to skipping meals to save money since starting college a few months ago. But she wasn’t going to make it through the next two hours of data entry and sleep monitoring if she didn’t get some caffeine. No wonder none of the upperclassmen had wanted to fill in during break.

Marin’s gaze slid over to the stairwell. If she stayed on the other side of the hall in the shadows, she could probably sneak by unnoticed. She moved to the right side wall and crept forward on quiet feet. But as soon as she got within a few steps of the shaft of light coming from the occupied room, a large shadow blotted it into darkness.

She’d been so focused on that beam of light that it took her a moment to register what had happened. She froze and her gaze hopped upward, landing on the guy who filled the doorway. No, not just any guy, a very familiar guy. Tall and lean and effortlessly disheveled. Everything inside her went on alert. Oh, God, not him.

He had his hand braced on the doorjamb, and his expression was as surprised as hers probably was. “What the hell?”

“I—” She could already feel her face heating and her throat closing—some bizarre, instant response she seemed to have to this man. She’d spent way too many hours in the back of her Intro to Human Sexuality class memorizing each little detail of Donovan West. Well, his profile, really. And his walk. And the way his shoulders filled out his T-shirts. As a teaching assistant, he usually only stopped in at the beginning of class to bring Professor Paxton papers or something. But each time he walked in now, it was like some bat signal for her body to go haywire.

It’d started with the day he’d had to take over the lecture when Professor Paxton was sick. He’d talked about arousal and the physical mechanics of that process. It was technical. He’d been wearing a T-shirt that read Sometimes I Feel Like a Total Freud. It shouldn’t have been sexy. But Lord, it’d been one of the hottest experiences of her life. He’d talked with his hands a lot and had obviously been a little nervous to be in front of the class. But at the same time, he’d been so confident in the information, had answered questions with all this enthusiasm. Marin hadn’t heard a word in the rest of her classes that day for all the fantasizing she’d been doing.

But now she was staring. And blushing. And generally looking like an idiot. Yay.

She turned fully toward him and cleared her throat, trying to form some kind of non-weird response. But when her gaze quickly traveled over him again, all semblance of language left her. Oh, shit. She tried to drag her focus back to his face and cement it there. His very handsome face—a shadow of stubble, bright blue eyes, hair that fell a little too long around the ears. Lips that she’d thought way too much about. All good. All great.

But despite the nice view, she couldn’t ignore the thing in the bottom edge of her vision, the thing that had caught her attention on that quick once-over. The hard outline in his jeans screamed at her to stare—to analyze, to burn the picture into her brain. The need to look warred with embarrassment. The latter finally won and her cheeks flared even hotter. She adjusted her glasses. “Uh, yeah, hi. Sorry. I thought I was alone in the building. Didn’t mean to interrupt . . . whatever.”

He stared at her for a second, his brows knitting. “Interrupt?”

Goddammit, her gaze flicked there again. The view was like a siren song she couldn’t ignore. Massive erection, dead ahead! She glanced away. But not quick enough for him not to notice.

“Ah, shit.” He stepped behind the doorway and hid his bottom half. “Sorry. It’s uh . . . not what it looks like.”

She snorted, an involuntary, nervous, half-choking noise that seemed to echo in the cavernous hallway. Really smooth. She tried to force some kind of wit past the awkwardness that was overtaking her. “Ohh-kay. If you say so.”

He laughed, this deep chuckle that seemed to come straight out of his chest and fill the space between them with warmth. Lord, even his laugh was sexy. So not fair.

“Well, okay, it is that. But why it’s there is just an occupational hazard.”

His laugh and easy tone settled her some. Or maybe it was the fact that he was obviously feeling awkward, too. “Occupational hazard? Must be more interesting than the sleep lab.”

He jabbed a thumb toward the office. “It is. Sexuality department. I’m working on my dissertation under Professor Paxton.”

She could tell he didn’t recognize her from class. Not surprising since she sat in the back of the large stadium-style room and tried to be as invisible as possible. Plus, she was wearing her glasses tonight. “I’m with Professor Roberts. I’m monitoring the sleep study tonight.”

“Oh, right on. I didn’t realize he’d taken on another grad student. I’m Donovan, by the way.”

I know.

“Mari.” The nickname rolled off her lips. No one called her that anymore. But she knew he probably graded her papers, and the name Marin wasn’t all that common. She forced a small smile, not correcting him that she was about as far from a grad student as she could get. She wanted to be one. Would be one day if she could figure out how to afford it. She’d managed to test out of two semesters of classes, but high IQ or not, that dream was still a long way off—a point of light at the end of a very long, twisting tunnel.

Marin shifted on her feet. “I was heading to get a Coke so that I don’t fall asleep from doing data entry and watching people snore. You need anything?”

“A Coke?” He glanced down the hall. “Don’t waste a buck fifty on the vending machine. I’ve got a mini-fridge in here. You can come in and grab whatever you want.”

Are you an option? I’d like to grab you. The errant thought made her bite her lips together so none of those words would accidentally slip out. She had no idea where this side of herself was coming from. Not that she’d really know what to do after she grabbed Donovan anyway. This was a twentysomething-year-old man, not one of the few boys she’d awkwardly made out with in high school. This was a guy who’d know how to do all those things she’d only read about in books.

“No, that’s okay, I mean . . .” She shifted her gaze away, willing her face not to go red again.

He caught her meaning and laughed. “Oh, right. Sorry. Yes, you should probably avoid strange men with erections who invite you inside for a drink. Good safety plan, Mari.” He lifted his hands and stepped back fully into the doorway, the pronounced outline in his pants gone. “But I promise, you’re all good now. You just caught me at an . . . unfortunate moment. And now I’m going to bribe you with free soda so that you don’t tell the other grads in the department about what you saw. I keep these late hours and work through holidays to avoid that kind of torture.”

He gave her a tilted smile that made something flutter in her chest. She should probably head straight back to the office she was supposed to be working in. He was older. Kind of her teacher. If he found out she was one of Pax’s students, he’d probably freak out that she’d seen him like this. But the chance to spend a few minutes with him was too tempting to pass up.

“Okay.”
