"You want your professor to fuck you?" He nuzzled and kissed my neck. "You want this thick cock stretching your tight cunt?"

He slapped my thigh and rubbed it. He fucking wants me.

I stopped rubbing my cunt and brought my fingers to his veiny cock. It was hot, and thick, and--most importantly--ready. I pointed it at my wet slit and slowly guided my professor into me.

He took over, gently easing me back onto the desk as I moaned and helped work his cock into me. He couldn't hold back his own moans, and rubbed my tits as he drank in the view before him. Before I could register his cock inside me, he brought my legs around and up, over his shoulders, and heard him grunt as he guided himself deeper.

"You should have been--grunt--focused during classes." He slowly, tantalizingly drew his cock in, out, in, out, of my wet cunt. "What you get here--grunt--is what you--grunt--focused on. Grunt--We could have been--grunt--we could've talked about--grunt--about the subject material. Grunt--You--grunt--you focused on my cock instead--grunt--like a good little slut."

"Yes--yes, Professor," I moaned.

Grunting, he sped up, grabbing my ass and holding my hips up. His powerful thrusts made my tits rock back and forth, and every few strokes, he'd slap one or the other.

I moaned with every slap, not caring if there was anyone else around to hear what we were doing. My hips bucked and shook with his thrusts, but his massive hands kept me tethered to his thrusting cock.

"Louder," he growled. "I can't fucking hear you." He thrusted even harder, moving his hips in little circles, stretching my cunt even more.

This drove me fucking crazy, and I groaned louder.

"Louder, slut, I want you screaming."

"Yes, Professor!" I cried out, moaning like a pornstar having the time of her life, loud enough for the whole hall to hear. My pussy buzzed with electric ecstasy, and his thrusts rocked my tits up and down.

He growled, slapped my tits again, and slipped out of my cunt, causing me to whimper. Before I knew what was happening, he flipped me onto my chest, brushed my dress out of the way, and smacked my ass.

I giggled and yelped as he did, and I wiggled to present myself to my professor. "Teach me a lesson, Professor," I moaned.

He lifted my ass by the hips and worked his way back into my slit, making me moan into the desk. A part of me ached for someone to walk into the office and see what we were doing. What I had driven my professor to do.

He pulled my hair and held my head to the desk. "Now let's see how this little slut cums on her professor's cock." He started thrusting again, slowly working back to the pace he was fucking me at before.

"Yess--yes--yess, professor," I grunted with every thrust, until I couldn't speak anymore. My arms went limp, trying to reach up for the other edge of the table, as I completely surrendered myself to my professor's pumping cock. I clenched on it as he circled my clit with his thick finger, but his girthy cock is what really pushed me closer and closer to the edge.

"Are you gonna fucking--grunt--fucking pay attention--grunt--in your classes now, slut?"

"Moan" is all I could make out.

He slapped my ass again, hard. "Fucking answer me, whore."

"Y-yes, Pro--grunt--fessor--grunt--"

He growled and gripped my hair, pulling my head back just enough to feel fucking amazing. If I had known my professor knew how to fuck a woman like this, I'd have "cleared the air" a whole hell of a lot sooner.

I trembled and jerked and moaned, my orgasm building and coming fast - it doesn't take much more - I grunt and moan loud, truly lost on his cock. I came and trembled and shook and writhed on his desk.

As my orgasm ended, he slipped his still-hard cock from me. I couldn't see what he was doing, but I heard him moving, and felt his mouth latch onto my cunt. His teeth brushed my clit and his tongue dug into my slit, and he moaned, "So fucking delicious," into my folds.

He suddenly pulled away and slapped my ass again. "On your knees now." He rose and began slowly stroking his wet cock again.

"Yes, Professor," I breathed. I slid down from the desk onto the rough carpet floor and knelt before my professor, my tongue stuck out obediently.

"Push your breasts out," he ordered. His eyes looked intensely at me as he stepped forward, like he was fucking my soul as he stroked his cock. It sent a shiver down my spine, if I'm honest.

He stroked himself faster, and rolled his head back. In the dim light, I saw sweat bunching his salt-and-pepper hair. It was another couple strokes when he groaned louder, pointed his cock at my face, and started shooting thick ropes of warm cum on my face, mouth, even my hair.

I pushed my tits up and out obediently, feeling his cum drip from my chin to my tits, and tasted my professor's cum on my tongue.

"Oh--oh fuck," he panted.

"Professor," I moaned, "may I come back again for another lesson, Professor?"

"You definitely need another lesson," he says with a dreamy smile, wiping the cum from my hair.

"Yes, Professor," I said as I took his still-dripping cock into my mouth, sucking and cleaning his and my cum from it, feeling his veins run along my lips as I bobbed on his cock.

"Good girl," he moaned, his cock shrinking on my tongue.

After I wiped and sucked the last bits of our dirty lesson from my face and chest, I joked, "I should've come to your office hours ages ago, Professor!"

"It's never too late," he reached down and helped me to my feet, "to get a professor's firm guidance."

"Help me tie my dress, Professor?"

He nibbled the back of my neck and gently traced his fingers along my back as he tied the dress again. When he was done, he whipped me around to look deeply into my eyes. After a long, tense, dreamy moment, he leaned down and pressed a warm kiss onto my lips, one that I hungrily returned.

He breathed hard, wrapped his arms around me, and nibbled my lips, before finally pulling away. He wiped away little lines of cum I'd missed and lifted his finger for me to suck. I took his fingers to the knuckle as I sucked his cum from his fingers.

"Thank you for all your help, Professor," I turned to leave.

"Call me, baby," he growled in my ear, slapping my ass.

As I moved towards the door, I saw the door never fully shut earlier. Oh, well.

I stepped out confidently, with a wicked smirk on my face, and noticed other hallways--which were dark when I entered--were bright and illuminated now, as though someone in another office had come in.

It was just a feeling, but I think someone might've heard my little lesson with the professor.

I walked out smugly, and drove home buzzing. I searched through my bag for the syllabus, and prayed the number on it was his cell.

I sent, just in case it wasn't him: Professor, I really enjoyed our lesson today, but I think I need more!

A few moments later, with a little selfie attached: Of course you do, slut. That's what happens when bad girls don't pay attention in class. Teach you a lesson again soon, baby.
