Tenderness poured from him, engulfing her in a bright glow of hope and satisfaction. Right now, his approval was the only thing that mattered. He’d given her so much in their short time together, opened the doors of her soul to delights she’d never imagined she’d enjoy or thirst to repeat.

“I want to please you,” she whispered.

“You do, sweetheart.” Smiling against the curve of her neck, he trailed light kisses next to the thin band encircling her throat.

Emboldened by his show of affection, she persisted. “Not the experiment, Doctor. You’ve already given me so much insight into my desires. Let me repay you.”

As though stung, Kurt jerked away from her.

“Damn it, Becca. For all your pliancy, you still don’t understand, do you? There’s no debt between us. I wanted this as much as you.” His clipped tone bounced around the bright lab. The rapid fluctuation of his moods threw her off balance.

“I know the experiment is important to you.” Surprised by his sudden withdrawal, she considered keeping quiet but she wanted him to appreciate her perspective. She goaded him, true, but the new Becca refused to demur. He’d seared away the careful distance that would have stopped her before. This is what he’d get.

Tired of half-truths and innuendo, she had to understand once and for all if his fondness extended beyond their professional relationship. Passion had muddied the water earlier making her perception murky. She refused to live with uncertainty any longer.

“That’s not what I meant, though. I want to do something for
you
. The man, not the doctor. What do you want from me, Kurt?”

“Becca, stop.” He covered her mouth with his palm as though to prevent her from tripping him over the edge of reason. “You don’t understand what you’re asking.”

She thought he was the one who didn’t understand. Frustrated, she cursed her lack of experience. She knew what she felt for him but she couldn’t decode the mixed signals he broadcast. He got angry when she implied he fucked her for the sake of the experiment but stopped her from expressing her budding attachment. What other options were there?

Her determination wavered. What if she made a fool of herself?

The scent of his skin made her weak so she obeyed his order for silence. However, she continued her relentless assault on his control. Going with instinct, she bestowed a soft kiss on his palm as if she were a subject paying allegiance to a king. The gesture mitigated some of the unintentional damage she’d done to their easy mood. He withdrew his hand to trace her lips with his finger, eyes softening again.

Regaining some of her composure, she whispered, “Then show me. Make me understand.”

As she waited for him to proceed, she couldn’t help but taste him. She closed her lips around his finger then sucked on it, moaning when his pupils dilated. The grey depths of his eyes looked like a sky reflecting a coming storm. Her pussy responded to his show of desire. Longing blossomed inside her.

How could she possibly want him again so soon?

“You need a demonstration of how we affect each other.” The pensive statement made it seem he spoke to himself. “First, the easy part. I’ll confirm your body responds more to my touch than to other stimuli.”

Rebecca groaned. She didn’t need Kurt to validate his skills as a lover. She’d already admitted he brought her more pleasure than she’d ever dreamed possible. She wondered about the effect she had on his mind and heart but the evident determination in his stance made it clear he wouldn’t be swayed from whatever course he’d set for them.

After tugging his lab coat over his bare muscles, he displayed the readings from their session the day before on the monitor in front of her.

“Look, Becca.” He pointed to the line on the top half of the screen then assumed his lecture tone as though he had to stay detached in order to make it through this lesson undistracted. That he relied on the crutch gave her hope. “This is the baseline average of your response from initial touch to orgasm during our trials yesterday.”

Even her newfound boldness couldn’t prevent her face from heating as she recalled coming again and again while he observed her. Rebecca whimpered.

In a dangerous mood, Kurt narrowed his eyes, almost daring her to object. Unsure of what had displeased him, she concentrated on staying still and relaxed in the grip of the restraints although her earlier sense of security had dissipated somewhat. Unqualified surrender would be so much easier if his feelings were clear to her.

“Now, the results from today’s session are being added to the graph.” His grin turned sinful as the readings spread out in a line trending blatantly above the baseline.

“Compare the level of your arousal from beginning to end. Today’s sample is higher at every single data point.” A groan reached her ears as he performed a quick review of the results. They must have confirmed his experience because Kurt nodded to himself. Then he pointed out a marked difference. “Here, just before and during orgasm in this afternoon’s session, the line spikes off the charts. The subject’s vaginal muscles squeezed the sheath tool with enough pressure to compress it to the absolute minimum thickness.”

She gulped, squashing a plea for a repeat performance of his thick cock tunneling through the muscles that had clenched around it. Instead, Rebecca waited for him to continue, to see where he took this line of reasoning.

How could he keep it physical and ignore any hint of emotion?

“You’ve completed many successful experiments as my assistant. You’re an outstanding researcher.

Although there aren’t enough records for a complete scientific study, this is enough to form a theory.” He paused, and then asked in his most patient voice, the one he reserved for slow students, “What does this tell you, Becca?”

She resisted putting herself in a one-down position by admitting her desire for more if he wouldn’t do the same. Reluctant to divulge her imprudent infatuation with the doctor—though it was plain as day to her, Dr.

Foster and, soon, the rest of their colleagues on the review board—she drew on her professionalism and reserve.

She avoided the obvious answer to his question with tact.

“There are a number of theories one could generate based on the given data set.”

Afraid Kurt would recognize her cool logic for a convenient mask to cower behind, she maintained a straight face. Either he believed her or he couldn’t resist playing along simply to make her admit the truth. Why would he do this? Why make their relationship more awkward if he didn’t return her affection?

“True. Tell me a few,” he commanded. Crossing the room to the whiteboard, he uncapped a dry erase marker and prepared to take notes. This familiar routine called to mind many previous brainstorming sessions despite the fact she’d never been naked and tied open for his perusal during one before.

Rebecca dissected the question as she would in any other case, hoping to gain some distance from the intensity of the situation. “The baseline involved manual stimulation by the subject whereas, during the trial, an outside source aroused the subject.”

“What else?” he pushed.

“The object inserted in the subject’s vagina was larger during the trial than in the baseline creation phase, which could have been the cause of the subject’s enhanced response.”

Her mind screamed for her to stop talking. She made the situation worse with every syllable she uttered but the researcher in her couldn’t help but uncover the flaws inherent in his comparison. Besides, she didn’t want to admit either to herself or Dr. Foster that she would never obtain sexual fulfillment this complete in all her life once the experiment finished and Kurt reverted to being her boss…no, partner. Not her lover.

“Any other discrepancies, Becca?” Kurt’s arched eyebrow dared her to come up with more reasons to deny their connection. After all, he intended to prove her wrong.

“You’re so hot.” The thought slipped out before she could translate it into scientific language.

At least he didn’t laugh in her face. Although, judging by his lips clamped together and his shaking shoulders, it required monumental effort on his part not to. She scrambled to recover.

“W-What I mean is, the inserted device during the baseline creation had a much cooler average temperature than the one used during the trial this afternoon.” The memory of his heated flesh scalding her chest, between her thighs and inside her pussy made Rebecca shiver as though she might freeze without his searing touch. The band across her abdomen seemed to constrict when her hips shifted at the memory of Dr. Foster fucking her.

Kurt jotted down the last of her ridiculous assertions with hasty strokes before adding his own theory in bold, printed letters.

“The subject responded more intensely due to her underlying attraction to her partner.”

Snapping the lid on the marker, he deposited it in the tray before spinning to face her. In the small space, he crossed to her side in two steps.

“And I’ll prove it to you.”

When Rebecca opened her mouth to ask how Kurt intended to confirm his theory, he silenced her with a brutal kiss. This time she thrust inside the inviting warmth of his mouth, parrying jabs of his tongue with her own. Dazed by the rush of pleasure, she didn’t realize he’d started to retreat until their lips separated with a smack.

As though he could read her mind, he said, “You’ll see.”

He rummaged through the cabinet behind her, hunting for God knew what. She drummed her fingers on the table. Not a very patient person, curiosity got the better of her. “What are you looking for?”

“One of my more recent inventions. I hadn’t intended to use it yet but this is a perfect opportunity for a test run.”

She strained against the bonds to lift her head but couldn’t see what contraption he’d retrieved no matter how she squirmed and struggled against the straps. After removing another component from the closet, he crossed to the sink then tinkered with something on the countertop. As he worked, he spoke in his seductive, midnight tone.

“So, we have as possible alternate theories that the inserted device in today’s session was bigger, hotter and remotely operated as compared with the method used in the baseline creation session, correct?”

When she didn’t respond, Kurt pivoted. His dark eyes bored into her, daring her to defy him.

“Yes, Doctor.”

“Then this should help disprove your suggestions.” He offered a deflated sphere, constructed of his flesh-colored material with a slender tube protruding from the back, for her inspection.

“What…what is it?” Her stomach did summersaults at the thought of yet another of his devious implements.

“I don’t have a name for it yet. Maybe you can suggest one after you try it out.” His dimples reappeared.

The straps sank into her flesh as she squirmed beneath them. Judging by the sight of his cock rising higher with every heartbeat, Rebecca deduced he’d relish debunking her hypotheses.

“God, baby. Look at you.” Kurt’s eyes raked down her body, kindling an inferno of need.

Her nipples hardened beneath his appraising stare, her mouth fell open and she began to rock against the clasp of the restraints. She surrendered to the passion flooding her.

“You enjoy being my subject, don’t you?”

Her eyelids fluttered closed as she tried to bring herself to refute his claim. It was no use. “Yes, Doctor.”

“Good girl.” Kurt patted her hip as he circled the table to stand between her legs. “I bet if I push my finger into your pussy right now you’ll be soaking wet. Should we test out that idea, too?” Without waiting for an answer, he slid one digit inside her. “You’re still so snug. Even after taking my dick less than an hour ago.”

Her moan reverberated off the white linoleum floor and the stainless steel cabinets, which amplified the animalistic sound. Kurt removed his finger from her grip. As she watched, he tasted the remnants of their desire.

Slipping his finger in his sexy mouth, he ingested the mix without glancing away from her, not even to blink.

What would the mingled flavors be like?

“I love the way you taste, Becca,” he murmured as she strained beneath him on the table, desperate to get closer. “Soon I’ll have you again but, for now, we have work to do.”

Rebecca had lost track of their intent. Struggling to focus, she grasped for a shred of self-control. He returned her to the task at hand with a light slap on the inside of her thigh. The resulting sting didn’t really hurt but it got her attention. Instead of shrieking or protesting, another moan escaped her when the spark of arousal ran up her leg.

Kurt began a narrative documenting his actions. He dictated each step of his procedure as he had on the more mundane experiments she’d assisted him with over the years. The familiarity of the situation contrasted with the building tension she braced herself to contain.

“First, I’ve rolled the device into a thin cylinder of material. I’ll take the moisture seeping from your slit to lubricate it.” Hearing him speak such blatant, unprofessional and arousing words aimed at her was surreal. His dirty-talk inflamed her already rioting senses but his speech couldn’t compare to the initial brush of his fingers against her moist, swollen flesh.

“Mmmmm.”

Kurt doused the end of the device in the copious secretions coating her pussy. The rolled up material would be smaller than his erect staff but the anticipation, while it hovered a hairsbreadth from entering her, drove her wild. As though he understood, and couldn’t resist toying with her, he paused.

“I’ve prepared the device and will now begin the insertion.” Kurt aligned the blunt tip of his creation with her channel. He embedded it in her pussy with a single long stroke.
