I walked into Mr. Harlan's classroom after the final bell, knowing exactly why he kept me late. The guy was built like a linebacker, thick arms straining his button-down, and he'd been eye-fucking me all semester. I was eighteen, legal, and tired of pretending I didn't want his cock.
"Close the door," he said, voice low and rough. I did. He locked it.
"Strip," he ordered.
I yanked off my shirt and shoved my jeans down. My dick was already hard, slapping against my stomach. Harlan didn't waste time. He grabbed me by the hair and pushed me to my knees.

"Suck it."
I unzipped him and pulled out his thick cock. It was heavy, veined, already leaking. I opened my mouth and took him deep, gagging when he thrust forward. He fucked my throat like he owned it, spit dripping down my chin. "That's it, take every inch, you filthy little slut."
He pulled out and spun me around, bending me over his desk. Papers scattered. My ass was up, hole exposed. He spit on it and shoved two fingers in without warning. I grunted, pushing back. "More."
Harlan added a third finger, stretching me open fast and rough. Then he lined up his cock and slammed in balls-deep. I cried out, the burn mixing with pure heat. He didn't ease up. He pounded me hard, desk legs scraping the floor with every thrust. Skin slapped skin. His balls smacked my ass.
"Fuck, your hole's tight," he growled, gripping my hips hard enough to bruise. He reached around and jerked my cock in time with his thrusts. Pre-cum smeared his hand. I moaned loud, not caring who might hear.
He flipped me onto my back on the desk, legs over his shoulders, and drove back in. His cock hit my prostate every time. Sweat ran down his chest. I grabbed my own dick and stroked while he railed me. "Gonna fill you up," he warned.
"Do it," I begged. "Cum in me."
Harlan slammed in one last time and unloaded, hot pulses flooding my ass. The feeling pushed me over. I shot ropes across my stomach and chest, groaning like an animal.
He pulled out slow, watching his cum leak from my hole. Then he dragged me to the floor and made me lick his cock clean. I swallowed every drop.
After, he tossed me my clothes. "Same time tomorrow," he said. "Don't be late."
I walked out sore, leaking, and already hard again for the next round.
