She stayed after class like always, the last one in the room, locking the door behind the others without being told. Professor Hale didn't look up from his desk at first. He just said, "On your knees, pet. Now."
Emma dropped fast, skirt riding up her thighs as she crawled the short distance.
She unbuckled his belt with eager fingers, freed his thick cock, and took it straight into her mouth. No teasing. She sucked hard, gagging when he grabbed her hair and pushed deeper. Spit ran down her chin while he fucked her face in short, rough thrusts.
"Look at you," he growled. "Class pet acting like a cheap whore the second the door's locked. You been wet all lecture thinking about this cock?"
She moaned around him, nodding as best she could. Her hand slipped under her skirt, rubbing her soaked pussy through thin panties. He noticed and yanked her up by the hair.
"Hands on the desk. Ass out."
Emma bent over, cheek pressed to the cool wood. He flipped her skirt up, ripped the panties aside, and drove two fingers straight into her cunt. She was dripping, and the wet sounds filled the empty classroom as he pumped her hard.
"Fuck, you're always ready," he muttered. He pulled his fingers out, slapped her ass once, then lined up his cock and shoved in deep. One thrust buried him to the balls. Emma cried out, gripping the edge of the desk.
He didn't give her time to adjust. He fucked her fast and dirty, hips slapping against her ass, one hand pinning her lower back while the other reached around to rub her clit in tight circles. "This pussy belongs to me during office hours. Say it."
"Yours," she gasped. "My cunt's yours, Professor."
He pulled out, spun her around, and lifted her onto the desk. Legs spread wide, he slammed back in. Papers scattered to the floor. He leaned over her, biting her neck while he pounded. Her tits bounced with every thrust; he yanked her shirt open and sucked a nipple hard.
Emma came first, legs shaking, pussy clenching around him. He kept going, using her through it, then pulled out and shoved her to her knees again. She opened her mouth obediently as he stroked his cock and painted her tongue and lips with thick ropes of cum. She swallowed what she could and licked the rest from his shaft.
After, he wiped her mouth with his thumb and fed it to her. "Good girl. Same time tomorrow. And don't wear panties next time."
She stood on shaky legs, straightened her clothes, and left with his taste still on her tongue, already counting the hours until the next lesson.
