I walked into Professor Hale's office after class like I had every Tuesday, but this time the door clicked shut behind me with a different weight. He was forty-two, built like he still lifted heavy, and he didn't waste time on small talk. "Lock it," he said, voice low. I turned the bolt. He stood up from his desk, loosened his tie, and told me to strip. No hesitation, no romance. I pulled off my shirt, kicked off my shoes, and dropped my jeans and briefs in a pile on the floor. My cock was already half-hard and twitching under his stare.
Hale stepped close, grabbed my dick in one rough hand, and stroked it twice, hard and fast, until it stood straight up. "On your knees," he ordered. I dropped. He unzipped, pulled out a thick, veined cock already leaking at the tip, and fed it straight into my mouth. No warm-up. I opened wide and took the first few inches, tongue flat, sucking hard while he pushed deeper. He tasted clean and salty. Spit ran down my chin as he started fucking my throat in short, steady thrusts. I gagged once and he didn't stop; he just held the back of my head and kept going until my nose pressed against his belt.
After a minute he pulled out, yanked me up by the arm, and bent me over his desk. Papers scattered. He kicked my feet apart, spit on his fingers, and shoved two straight into my ass. No lube, just spit and pressure. I grunted at the burn but pushed back anyway. He worked them in and out, twisting, stretching me open while his other hand pinned my lower back. "Tight little student hole," he muttered. Then he lined up his cock and pushed in.
The stretch was brutal at first. He didn't ease in; he drove forward until his balls pressed against me. I bit my forearm to stay quiet while he started pounding. Each thrust slammed the desk against the wall. His cock dragged over my prostate on every stroke, turning the ache into something hotter. Sweat dripped off his chest onto my back. He reached under me, grabbed my cock, and jerked it in time with his fucking. Precum smeared his fingers and the desk.
He pulled out, flipped me onto my back on the desk, and shoved back in. Now I could see his face, jaw tight, eyes locked on where his cock disappeared into me. He hooked my legs over his shoulders and fucked harder, balls slapping. I reached down and stroked myself while he railed me.

The slap of skin and wet sounds filled the office. When I got close he knocked my hand away and took over, jerking me rough and fast until I shot ropes across my stomach and chest. My ass clamped down on him. He groaned once, buried himself deep, and unloaded. I felt every pulse of his cum flooding inside me.
He stayed buried for a long minute, breathing hard, then pulled out slow. Cum leaked out of me onto the desk. Hale wiped his cock on my thigh, tucked himself away, and told me to clean up and come back next Tuesday. I pulled my clothes on with his load still dripping down my leg. By the time I reached the door my cock was already getting hard again at the thought of the next visit.
