I was grading papers in my office when she walked in. Jasmine, my top student in the lit seminar, twenty-two years old, tight black body poured into a short skirt and a tank top that barely held her heavy tits. She shut the door behind her and locked it without asking.
"Professor, I can't stop thinking about it," she said, voice low and hungry. "That giant white cock of yours. I saw the outline in your pants last week.

I need it."
I leaned back in my chair. "Jasmine, this is dangerous."
She didn't care. She dropped to her knees right there on the office carpet, unzipped me, and pulled my thick white dick out. It was already half-hard and growing fast. Her dark fingers wrapped around the pale shaft, stroking slow and firm.
"Fuck, it's so big," she whispered. "White dick like this is what I dream about." She licked the head, tasting the precum, then opened wide and took me deep. Her warm mouth stretched around my girth, tongue working the underside while she bobbed her head. Spit ran down my balls as she gagged herself trying to take more.
I grabbed her braids and fucked her face, pushing until her nose pressed against my stomach. She moaned around the shaft, eyes watering but never pulling back. When I pulled out, strings of saliva connected her lips to my cock.
"Get up," I told her. "Bend over the desk."
She did it fast, hiking her skirt up. No panties. Her round black ass was perfect, smooth dark skin begging for my hands. I spread her cheeks and rubbed my giant white cock between them, sliding the head over her wet pussy lips.
"Put it in," she begged. "I want that thick white meat stretching my black cunt."
I slammed in hard. Her tight hole gripped me like a fist, hot and slick. I bottomed out on the first thrust, balls slapping her clit. Jasmine cried out, pushing back to take every inch. I fucked her rough, gripping her hips, watching my pale cock disappear into her dark pussy again and again. The contrast made me throb harder.
She reached back and spread herself wider. "Harder, professor. Wreck this black pussy with your giant white cock."
I pounded her, desk creaking under us. Her juices coated my shaft, dripping down my balls. Every time I pulled out I could see her pink insides gripping me before I drove back in. She came fast, legs shaking, pussy pulsing around my dick, but I didn't stop. I flipped her onto her back on the desk, hooked her legs over my shoulders, and kept driving deep.
Her tits bounced with every thrust. I leaned down and sucked one dark nipple hard while I fucked her. She clawed my back, moaning filthy shit about how she needed white cock every day now, how nothing else would do.
I pulled out and shoved my cock into her mouth again so she could taste her own pussy on it. She sucked greedily, then I bent her over the desk once more, this time spreading her ass and pressing the head against her tight asshole.
"Yes," she hissed. "Fuck my black ass with that giant white cock."
I worked it in slow at first, then faster once she relaxed. Her ass was even tighter, gripping every vein. I reached around and rubbed her clit while I railed her. She came again, screaming into her arm so no one outside would hear.
Finally I couldn't hold back. I pulled out, spun her around, and stroked my cock over her face. Thick ropes of cum shot across her dark skin, painting her cheeks, lips, and tits. She licked what she could reach, swallowing every drop she caught.
Afterward she smiled up at me, cum still on her chin. "Same time tomorrow?"
I knew this was only the start. She wanted my giant white cock, and she was going to get it whenever she asked.
