The classroom door clicked shut behind us, and I knew right then I had her. Emma was twenty-two, failing calculus, and desperate enough to stay late for "extra tutoring." She stood there in her tight skirt and low-cut top, pretending she didn't notice how my eyes dragged over her tits. "Mr. Harlan, I really need to pass this," she said, voice shaky. I didn't answer with words. I grabbed her by the hair and shoved her face down on the desk.
"Spread your legs, slut," I growled. She hesitated, so I yanked her skirt up and ripped her panties aside. Her pussy was already wet, the little traitor. I slapped her ass hard enough to leave a red handprint. "You came here to get fucked, didn't you? Forced into this because you're too dumb to study." Emma whimpered but pushed her hips back, offering that tight cunt. I unzipped and slammed my thick cock straight into her in one thrust. She cried out, but I didn't stop. I fucked her raw and deep, balls slapping against her clit with every stroke.
Her walls clenched around me like she was trying to milk every inch. "Fuck, you're tight," I grunted, pounding harder. Papers scattered off the desk as I used her body like a toy. Emma moaned louder, pushing back to meet my thrusts. "Please… harder, tutor." That word made me laugh. I reached around and rubbed her swollen clit in rough circles. "You don't get to beg. I'm the one forcing this lesson." I pulled out, flipped her onto her back, and shoved my cock into her mouth. She gagged but sucked greedily, spit dripping down her chin onto her exposed tits.
I face-fucked her until tears ran down her cheeks, then pulled back and bent her over again. This time I aimed lower, pressing the head of my cock against her asshole. "No," she gasped, but her body betrayed hershe was dripping down her thighs. I forced my way in slowly at first, then buried myself balls-deep in her ass. Emma screamed and came instantly, her pussy squirting onto the floor.

I didn't let up. I railed her ass with long, punishing strokes, calling her every filthy name while she shook through another orgasm.
When I was close, I yanked out and painted her face and tits with thick ropes of cum. She licked her lips, eyes glassy. "Same time tomorrow?" she whispered. I zipped up and tossed her a tissue. "Don't be late, or next time I'll bring a friend." She left with my load drying on her skin, and I knew the real tutoring had just begun. Every session after that got dirtierher on her knees under the desk during "office hours," bent over the hood of my car in the parking lot, or tied to the chair with my belt while I spanked her raw and fucked both holes until she couldn't walk straight. She passed the class, but she kept coming back for the forced lessons she secretly craved.
