Chapter 2

　　Professor Kelvin's eyes were almost black with lust now. He gripped my hair tighter and pulled me off his cock with a wet sound. His chest heaved as he stood up, towering over me.

　　"Stand up," he ordered, voice gravelly and commanding. "Turn around and bend over the desk. Hands flat on the wood."

　　A thrill shot through me. I rose on shaky legs, turned, and leaned forward over the large oak desk, pushing papers aside. I arched my back deeply, pushing my ass out toward him, skirt riding all the way up to my waist. My bare pussy was completely exposed — swollen, slick, and dripping with need.

　　He stepped behind me, one large hand smoothing over my ass cheek before delivering a sharp smack that made me gasp. The sting bloomed into heat.

　　"So fucking wet," he muttered, almost to himself. His fingers traced through my folds, spreading my juices. "You came here with no panties, dripping for your professor like a desperate whore. How long have you been fantasizing about this?"

　　"Since the first lecture," I admitted breathlessly as two thick fingers circled my clit, then pushed inside me. The stretch felt incredible. He curled them expertly, hitting that sensitive spot that made my knees buckle. "Every time you talked about taboo… I imagined you doing this to me."

　　He pumped his fingers faster, the obscene wet sounds filling the office. My juices coated his hand, dripping down my inner thighs. I moaned loudly, no longer trying to stay quiet.

　　"Quiet," he warned, but his actions contradicted the words — he added a third finger, stretching me wider, fucking me with them relentlessly while his thumb rubbed my clit in firm circles.

　　Pleasure built fast and vicious. My walls clenched greedily around his fingers. "Professor… I'm so close already…"

　　"Not yet." He withdrew his hand suddenly, leaving me empty and aching. I whimpered in protest.

　　Then I felt the blunt, hot head of his cock press against my entrance. He rubbed it up and down my slit, coating himself in my wetness, teasing me mercilessly.

　　"Beg for it," he demanded.

　　"Please," I gasped, pushing back against him. "Please fuck me, Professor. I need your cock inside me. Use me. Teach me how good the forbidden feels."

　　With a low growl, he gripped my hips and slammed into me in one powerful thrust. The sudden fullness made me cry out — he was thick, stretching my pussy to its limit, hitting deep. The burn mixed perfectly with pleasure.

　　He didn't start slow. He fucked me hard and deep from the very first stroke, the desk creaking loudly beneath us. Papers flew to the floor. The sound of skin slapping skin echoed obscenely. My breasts pressed against the wood, nipples hard and sensitive through my blouse.

　　"Fuck, you're so tight," he groaned, pounding into me. One hand reached around to rub my clit again while the other tangled in my hair, pulling my head back slightly. "Taking your professor's cock so well. Such a perfect little slut for me."

　　Every thrust sent waves of ecstasy through me. I could feel every vein, every inch of him dragging along my inner walls. My moans grew louder, unrestrained. The risk of someone hearing only heightened everything.

　　He changed the angle, hitting that perfect spot inside me over and over. My orgasm built like a tidal wave.

　　"I'm gonna come—" I warned, voice breaking.

　　"Come on my cock," he commanded, fucking me even harder. "Milk me like the dirty student you are."

　　The orgasm exploded through me. My pussy spasmed violently around his thick shaft, juices gushing as intense pleasure ripped through every nerve. I cried out, body shaking, vision blurring.

　　Professor Kelvin groaned deeply, burying himself to the hilt as he came hard, flooding me with hot, thick ropes of cum. I felt every pulse, every spurt filling me up.

　　We stayed locked together for long moments, panting, his cock still twitching inside my fluttering walls. Cum began to leak out around him, dripping down my thighs.

　　He finally pulled out slowly, watching with dark satisfaction as more of his seed trickled from my well-fucked pussy.

　　"Next time," he said, voice still rough as he zipped himself up, "you'll stay after my afternoon lecture. No panties. And we'll continue this lesson properly."

　　I straightened up on shaky legs, pulling my skirt down, feeling his cum continue to leak out of me. The mess only made me smile wickedly.

　　"Yes, Professor. I can't wait for the next class."

　　But deep down, I already knew one lesson wouldn't be enough.
