Mia sat in the back row of Professor Kanes evening lecture, legs spread just enough under her desk that the cool air hit her bare pussy. Shed skipped panties on purpose. Her short skirt rode up every time she shifted, and she knew he noticed. Kane kept glancing her way, his jaw tight, eyes dropping to her thighs before he forced them back to the board. The classroom emptied fast after class. Mia stayed.
She walked up to his desk as the last student left. I need extra help with the assignment, she said, voice flat and direct. Kane looked her over, then locked the door. No words wasted. He grabbed her by the hips, spun her around, and bent her over the desk. Her skirt flipped up. His hand slapped her ass once, hard.
Spread your legs, he ordered. Mia did. Kane unzipped, pulled out his thick cock, and rubbed the head against her already wet slit. No teasing. He pushed in deep on the first thrust, filling her cunt in one stroke. Mia grunted. He started fucking her right there, desk creaking, his balls slapping her clit with every drive. She reached back and spread her ass cheeks so he could go deeper. Kane grabbed her hair, yanked her head back, and pounded harder.
Fuck, your pussys tight, he growled. He pulled out, spun her to face him, and shoved her to her knees. Mia opened her mouth and took his cock to the back of her throat. Saliva ran down her chin as she sucked him wet and sloppy. Kane fucked her face, holding her head with both hands until she gagged. When he pulled out, strings of spit connected her lips to his shaft.
He lifted her onto the desk, spread her legs wide, and sank back into her cunt. Mia wrapped her ankles around his waist and met every thrust. Her tits bounced under her thin top. Kane yanked it down, sucked a nipple hard, then bit it. She came first, cunt clenching around his cock, juices leaking down his balls. He didnt stop. He kept slamming into her, desk scraping the floor, until he pulled out and shot thick ropes of cum across her stomach and tits.
They didnt speak. Kane wiped his cock on her thigh, zipped up, and unlocked the door. Mia pulled her top back into place, cum still sticky on her skin, and walked out with his load drying under her clothes. She came back the next night. Same desk. Same raw fucking. This time he bent her over the chair and took her ass, stretching her hole with spit and steady pressure until she was full of him again. He came deep inside her, then made her lick him clean before she left.
Every session after that stayed the same: no romance, no slow build, just hard, direct sex wherever he wanted it. Mia showed up wet and ready. Kane used her until they both got off, then sent her home marked with his cum. The arrangement lasted the whole semester. She aced the class. He kept filling her holes.
