A visiting professor can’t help sampling the local student body.

Last year I worked as a visiting professor at a foreign university. As part of my position, I was assigned my own student research assistant. It should go without saying that having sex with one’s assistant was a definite no-no.

But Katrina was my Kryptonite. She had sharp, perfectly sculpted cheekbones, sparkling blue eyes, and bubble-gum pink lips that curved into a perfect Cupid’s bow that begged to be kissed. She was gorgeous — lithe and delicate with curves in all the right places.

As hard as I tried to keep my thoughts about Katrina innocent and pure, sex seemed inevitable. Every conversation featured a subtle undercurrent of flirtation. It was a dangerous tightrope we both seemed determined to walk.

Our first hookup was in my office. We were going over a survey that had to be conducted for a quarterly report about my research project’s progress. Really tedious stuff that kept us holed up in the room for hours.

When I finally glanced at the clock, I was shocked to see that five hours had passed since we’d first sat down. We were both in desperate need of a break. My shoulders were stiff with tension. I stood and rolled my head from side to side to ease the ache.

Katrina tutted behind me. “Moving your head will not soothe sore muscles,” she scolded. She gestured to my chair. “Sit.”

I settled in the seat again, and her cool, deft fingertips immediately settled on either side of my neck. She circled over the knots in my muscles, applying the perfect amount of pressure. I groaned when she hit a particularly sore spot, grateful for her efforts.

As the tension left my neck, Katrina’s hands began to wander south. She skimmed along my torso, pausing to fan her fingers over my pecs before continuing her descent to my crotch. The moment her fingers landed on the zipper of my pants, we were at the point of no return. She didn’t fumble one bit. Nope, those agile fingertips easily slid down my zipper and popped the button at my waistband.

Katrina slipped her hands beneath my pants, and I lifted my hips slightly to aid her efforts as she pushed my slacks and boxers down to my knees. She knelt at my feet, angling that sweet face of hers so she could look up into my eyes.

“I’ve wanted this for a long time,” she whispered.

As she yanked my pants and underwear down farther, I toed off my loafers and then kicked away my clothing.

Sitting there in a rumpled, button-down shirt, I was speechless as one of Katrina’s hands slipped between my legs to cup my balls while the other embraced my erection. Her reverent touch promised endless pleasure, and I was eager to forget about rules and propriety in favor of just feeling.

“I gripped her head as she parted her full lips and enveloped my dick.”

As her silken tongue slid along the underside of my dick, I released a strangled breath from between my clenched teeth. The sensation was the sweetest torture, like a sizzling shock to the groin — jarring and approaching painful, yet my body responded with a yearning hunger for more.

Pre-come glistened at the tip of my cock, and Katrina flicked her tongue across the head to collect that bead of moisture. She purred her approval, and then swiped her tongue over my dick again. Every lick sent a jolt of pleasure  to my balls.

I groaned and gripped the sides of her head as she parted her full lips and enveloped my dick. Logic and lust were at war in my brain. I wanted to hold her head and just pump my cock into her, taking that pretty little mouth for all it was worth. At the same time her angelic face appeared so fragile, so delicate; I hesitated to unleash the full force of my desire.

I should have known she was anything but fragile. As Katrina continued to suck my dick, her little mews of amusement vibrated against my flesh, ratcheting up my arousal to previously unrealized heights. Every ounce of blood in my body rushed straight to my erection. Her mouth was working magic on me as my needs grew more acute.

Suddenly, Katrina changed her rhythm. After a few strokes, I realized she was sucking in time to the pulse of my dick. The thought that she could feel the strength of my desire right against her tongue nearly sent me over the edge right there. Only the selfish need to remain in her mouth for as long as possible held me back.

Then her fingertips tickled beneath my balls, and all illusions of self-control went out the window. The sensations were not unlike having a live wire plugged into my body. Every nerve seemed to sizzle as electric shocks of excruciating pleasure rocked me.

Even as my hips bucked wildly, Katrina continued to lick and suck, and when hot come surged from my dick, her lips clamped around me tighter. She continued to bob her head rhythmically as she swallowed my cream.

Afterward, she delicately dabbed her fingertips against her lips to remove any excess droplets of come. As if for extra insurance, she slid her tongue along them, too, emitting soft sounds of satisfaction before rising to her feet and walking behind me.

Katrina’s hands smoothed over my shoulders, pausing to rub out another knot. “There, nice and relaxed,” she purred. “Now we can get back to work.”

For someone who had just sucked me off like a porn star, Katrina was amazingly calm and collected. I turned to stare at her for a moment, dumbfounded as I desperately tried to find something smart and sophisticated to say. But my mind was blank — so much for being a loquacious scholar.

Though words failed me, I was overwhelmed by the desire to taste her pussy. Still, something inside me encouraged me to hold back. I regained my control, and we got back to work. Still, in the back of my mind, I began to contemplate what my next move would be in this dangerous game we were playing.

The following evening we had to attend a fundraising dinner for the university. We both had important roles to play. She was the beguiling young scholar whose job was to charm benefactors into donating to the scholarship fund, and I was to dazzle donors with my research.

You’d think that with such an important task at hand my libido would take a backseat. But there was no way. Now that I knew what Katrina’s mouth felt like on my dick, I was desperate for more.

By some stroke of fate, Katrina and I wound up seated at the same table. A stodgy European man who oozed old money sat to my left and Katrina’s delectable ass was parked to my right.

I did my best to engage the wealthy guests at our table, but all I could think about was what kind of panties Katrina wore beneath her tight dress — if any. The white, nearly see-through garment definitely didn’t allow for bold colors, and when I scoped her ass earlier there were no pantylines in sight. That left two possibilities: a pale, delicate thong or nothing at all.

My mouth watered as I considered both possibilities. Thongs always make a woman look sexy. They conjure up all sorts of kinky images in my mind. I could push the tiny triangle of material to the side, moving it just enough to take a taste of her slit. Or I could snap the thin elastic waistband with my teeth, allowing the silky scrap of fabric between her legs to fall, leaving nothing in my way. Of course, if she was going commando, I could dive right in.

“Her mouth was working magic on me as my needs grew more acute.”

Before I could consider what I was doing, my hand slid from my side to Katrina’s thigh. My fingers crept higher and higher, and I stroked the silky-smooth skin of her thighs, loving the deep red blush that bloomed on her cheeks. Her breaths had grown more shallow, each little burst of air making her breasts bounce.

The stodgy European said something to me. I turned to face him, easily answering his question while my fingers continued to work their magic beneath Katrina’s dress.

The tips of my fingers brushed against her wet slit, and I got the answer to my question: Katrina was going commando. The only thing standing between me and that deliciously damp pussy was a table full of boring benefactors.

Katrina was trying to conduct a conversation with the woman seated to her right, but she was clearly struggling to keep her composure. Mostly, Katrina seemed to nod in agreement to whatever the woman said, tricking her neighbor into believing that she’d found a kindred spirit at the world’s dullest academic dinner.

A part of me started to feel guilty for getting her so worked up in front of such influential people. I briefly considered stopping my actions, but then she slid a little lower in her seat to impale herself on my fingers. Once her wet heat closed around my digits, there was no turning back.

I twisted my wrist as much as the protective cover of the table linens would allow, knowing we needed to avoid detection. Then I crooked my fingers and pumped in and out of her. The walls of her pussy rippled around my fingers, and tension gripped me, beckoning me deeper.

Katrina’s rosy-red blush spread from her cheeks down to her neck and chest. She was such a pretty picture, causing my libido to roar with impatience.

My dick strained against my slacks. Finger-fucking her under the table wasn’t enough anymore. My body hummed with a wild, nagging need to get more than just my fingers inside her.

Suddenly, the lights dimmed and a hush fell over the room. The university’s president had taken the stage, and from what the rest of the staff had told me earlier, this signaled the beginning of a long-winded presentation that would occupy at least the next hour.

It was exactly the interruption I needed. I slid my fingers from Katrina’s crotch and squeezed her thigh to grab her attention. She angled her head toward me slightly, turning just enough to catch my nonverbal cue.

I discreetly nodded my head toward the door that led to the hall, trying to impart that I wanted us to meet outside. I quietly rose from my seat and headed out, fighting the urge to look over my shoulder to see if Katrina was following me.

Seconds after I’d crossed the threshold, a hand tapped at my shoulder. I whirled around to find Katrina, smiling.

I already knew exactly where I wanted to take her. Just above the banquet hall was the school’s humanities library. The study halls remained open 24 hours, but they seldom hosted any students that late in the evening.

I curled my fingers around Katrina’s wrist and tugged her toward the elevator bank. Fortunately, we didn’t have to wait long for the elevator to arrive. Unfortunately, it was full of underclassmen chattering about the project they intended to work on in   the library.

Our unwelcome company meant I was forced to keep my hands to myself. I was smart enough to realize that a professor pawing a student wouldn’t go unnoticed. So instead, I raked my eyes over every inch of Katrina’s deliciously curvy body. Her breasts were perfection; the perky globes sat high on her chest, threatening to burst from the low-cut neckline of her dress at any moment. I wanted to fuck those breasts, to slide my dick between them until the tip smacked against her chin. Her ass was another thing of beauty. Full, round cheeks stretched the material of her dress to its limits.

A loud ding reminded me of where we were. The elevators opened, and I allowed the group of students to head out before us, taking advantage of their turned backs to grab a handful of Katrina’s ass.

When we entered the library, I was relieved to see the group had already ambled off to a private study room. Other than those guys, the library appeared to be completely empty. There wasn’t even a librarian stationed at the desk. Perfect.

I pulled Katrina away from the study rooms. We wove through the aisles until we reached the very back of the library. This is where all of the cubbies for independent study were located.

Desks lined the entire back wall. Every single one had a tall partition on either side, a design that was meant to block other students from view.

I curled my fingers around Katrina’s waist and lifted her onto one of the desks. My hands ran along her thighs, coaxing them open. The slight opening of Katrina’s legs gave me my first real look at her snatch. She was obviously wet. The tiny sliver of deep pink that was visible was glistening with her arousal. But that little peek at her pussy wasn’t anywhere near enough to satisfy me.

My fingers gripped Katrina’s knees and shoved them apart until they smacked against the desk’s partitions. Now I could see what I was after. The plump lips of Katrina’s labia parted to reveal her bright pink center. I ducked between her legs and took a long, languid lick from her asshole to her clit. She tasted divine, like sin, sweets and sex all rolled into one decadent package.

“I withdrew my length slowly then drove into her with all my might.”

The sweet floral scent of her perfume mingled with her musk, flooding my senses. The more I licked, the wetter her cunt became. And the wetter she got, the more I wanted to lick. It was a vicious cycle with no end in sight.

But licking the slick slit between her legs didn’t satisfying me for long. I needed more. Torn between wanting to fuck her pussy and wanting to continue to lick her, I finally split the difference and plunged my tongue into her hot,  wet center.

The action earned me a low, throaty groan from Katrina. Keeping my mouth planted firmly on her pussy, I snaked my hand up her body to her face, pressing a finger against those pouty little lips. I hoped the gentle gesture would be enough to remind her that we had to keep quiet.

She got the hint, but her quiet whimpers turned me on even more.   Her pussy seemed to ripple over my tongue, and her ever flowing juices soaked my face. The time had come to fuck her senseless.

I pulled away from Katrina, making her whine with disapproval.

“Don’t worry,” I whispered. “I’ll take care of you.”

My dick jumped, eager to get out of my pants and into Katrina. I broke from her to pull a condom from my pocket. After the previous day’s activities, I had been sure to shove several in my pocket before leaving my apartment.

Truthfully, I was so worked up I’m surprised I didn’t explode from simply rolling the rubber onto my dick. Once I was finally sheathed, I teased her wet entrance with my cockhead, swirling it around the juices pooling there until she clutched me impatiently and yanked my body tighter to hers. 

When I finally plunged inside her cunt, I nearly lost consciousness. She was so tight. Her walls closed around my cock with a vise-like grip that instantly blurred the line between pain and pleasure. I slowly advanced until my pelvis was flush against hers.

Taking a fortifying breath, I stood still for a moment. Once her pussy muscles relaxed around me, I withdrew my length slowly then drove into her with all my might. The action slammed the desk on which she sat against the wall, making a loud rattling noise.

I hooked Katrina’s leg over my hip and pulled her closer against me. Her ass balanced precariously at the desk’s edge. I cupped an ass cheek and hauled her up against me. Then I used that leverage to piston into her like a wild man.

The new rhythm and increased speed already had my balls growing tight. It clearly affected Katrina as well. She whimpered into my neck, sucking at my flesh in an attempt to quiet her moans. I could relate; I was barely containing my own feral growls.

When Katrina’s whimpers turned to loud, throaty groans, I sealed my lips over hers to swallow the sounds. As much as I enjoyed the enthusiastic noises my efforts had caused, it would be bad for both of us if the sounds of our sex echoed through the otherwise silent library.

Katrina’s body began to shake under the force of her pleasure. Her thighs clamped tight around my hips — almost as tight as the walls of her pussy were gripping my dick.

Biting back a groan, I pulled out   until only the tip of my dick remained inside her clutching cunt. After another deep breath, I slammed into her again. The violent thrust triggered her unrelenting orgasm.

Katrina’s muscles rolled, rippled and twitched around me. Her honey rushed out of her in a steady stream, providing the extra lubrication I needed to drive myself dangerously close to the edge.

And oh how close I was. One, two, three more feverish thrusts, and I was gone, hurdling into the inviting abyss. Come jetted from my body into hers. I pumped into her relentlessly, not pausing until every last drop of semen left my body.

Right as I finished blowing my load into Katrina, I heard footsteps outside the study room. We looked at each other and froze for a second, and then we straightened our clothes and ran out through the back door into a deserted hallway.

We made it out of the library and back to the banquet hall without incident. Crazy sexual energy still sizzled between us. Continuing our affair for the rest of my time at the university was a total no-brainer. She was worth the risk.
