Dr. Marcus Reed leaned back in his leather chair, his dark skin gleaming under the low office light. At 42, he was all thick muscle and quiet command, his button-down stretched tight across his broad chest. Alex, 23 and struggling in Marcus's advanced lit seminar, had come for "extra help" after class. The door clicked shut behind him.
"You know why you're here," Marcus said, voice low and rough. He stood up, towering over the desk. "You've been staring at my dick all semester. Time to do something about it."
Alex swallowed hard but didn't argue. Marcus grabbed him by the shirt and yanked him close. Their mouths crashed together, tongues shoving deep. Marcus's hands went straight to Alex's ass, squeezing hard through his jeans before yanking them down. Alex's cock sprang out, already leaking.
"On your knees," Marcus ordered. Alex dropped fast. Marcus unzipped, pulling out a thick, veined black cock, heavy and half-hard. "Suck it. Show me how bad you want that A."
Alex opened wide and took the head in, tongue swirling around the fat tip. Marcus grunted and pushed deeper, feeding inch after inch until Alex gagged. "That's it. Choke on it." He gripped Alex's hair and started thrusting, fucking his mouth in steady strokes. Spit ran down Alex's chin. Marcus's balls slapped against his jaw with every push.
After a few minutes Marcus pulled out, cock shiny with spit. "Stand up. Bend over the desk."
Alex bent forward, ass up. Marcus kicked his legs apart and spat on his hole. Two thick fingers pushed in without warning, stretching him open. Alex moaned into the wood.
Marcus worked them in and out, scissoring, then added a third. "Tight little hole. Gonna wreck it."
He lined up his cock and shoved in. Alex cried out as the thick head popped past the ring. Marcus didn't wait. He drove the rest of the way in one hard thrust, balls deep. Alex's ass clenched around the fat shaft. Marcus started pounding, hips slapping loud against Alex's cheeks.
"Fuck, yeah. Take that dick," Marcus growled. He grabbed Alex's hips and hammered harder, the desk creaking under them. Each thrust bottomed out, Marcus's heavy cock stretching him wide. Pre-cum and spit slicked everything. Marcus reached under and stroked Alex's cock in time with his thrusts.
Alex was moaning nonstop, pushing back to meet every slam. Marcus leaned over him, chest pressed to his back, and bit his shoulder. "You like getting fucked by your professor? Say it."
"Yes, fuck, I love it," Alex gasped.
Marcus pulled out, flipped Alex onto his back on the desk, and shoved back in. He hooked Alex's legs over his shoulders and drilled down, cock punching deep. Sweat dripped from Marcus's body onto Alex's. The room filled with the wet sound of skin on skin and Alex's desperate whimpers.
Marcus's rhythm got rougher, balls tightening. "Gonna fill you up." He slammed in one last time and came hard, hot cum flooding Alex's ass in thick pulses. He kept thrusting through it, pushing the load deeper.
Alex came right after, shooting across his own stomach while Marcus's cock stayed buried inside him. They stayed locked together, breathing hard, Marcus's cum already starting to leak out around his softening shaft.
Marcus pulled out slow, watching the mess drip. "Office hours every Tuesday," he said, tucking his cock away. "Don't be late."
