I was sitting behind my desk after class when she shut the door and locked it. Maya, twenty-two, my star student in the senior seminar, stood there in a tight skirt that hugged her thick black ass and a low-cut top showing off those heavy tits. She walked straight up, eyes locked on my crotch like she already knew what was under there.
"Professor, I've been thinking about that giant white cock of yours all semester," she said, voice low and filthy. "I want it. Now."
I didn't waste time with questions. I stood up, unzipped, and hauled out my thick, veiny white dick. It was already half-hard and growing fast, nine inches of pale meat with a fat pink head. Maya's eyes widened and she licked her lips.
"Fuck, it's even bigger than I imagined," she muttered, dropping to her knees right there on the classroom floor. Her dark hands wrapped around the shaft, contrasting hard against my skin. She stroked me slow at first, then faster, spitting on the head and working the saliva down. "I need this white cock stretching my black pussy."
She opened wide and swallowed the head, tongue swirling around it like she was starving. I groaned and grabbed her braids, feeding more of my dick into her hot mouth. She gagged when it hit the back of her throat but didn't pull off. Instead she pushed forward, taking nearly half of it, drool running down her chin onto her tits. I fucked her face in short thrusts, watching my pale shaft disappear between those full black lips.
"Take it deeper, slut," I growled. She moaned around my cock and did, choking and slurping until her nose almost touched my stomach. Her throat squeezed tight. I pulled out, strings of spit connecting her mouth to my glistening dick, then slapped it across her cheeks.
Maya stood, hiked her skirt up, and bent over my desk. No panties. Her pussy was shaved smooth, dark lips already glistening wet. "Fuck me with that giant white cock," she begged, spreading her ass cheeks. "I want it balls-deep."
I lined up and shoved in. She was tight as hell, gripping every inch as I sank my thick white meat into her. Maya cried out, pushing back until her ass smacked against my hips. I bottomed out, my heavy balls resting against her clit. Then I started pounding. Hard, fast strokes that made her desk creak. Her pussy squelched around me, creamy white juices coating my shaft every time I pulled back.
"Goddamn, your black cunt feels so good on my white cock," I grunted, slapping her ass hard enough to leave red handprints. She pushed back, meeting every thrust. "Bigger than any black dick I've had," she panted. "Stretch me out, professor. Ruin this pussy."
I flipped her onto her back on the desk, hooked her legs over my shoulders, and drove back in. Her tits bounced with every slam. I leaned down and sucked one dark nipple into my mouth while my cock hammered her. Maya clawed at my back, moaning loud enough that someone might hear through the door.

I didn't care. I just kept drilling her, my giant white dick splitting her open again and again.
She came first, pussy clenching and pulsing around me, squirting a little around my shaft. I didn't stop. I flipped her again, bent her over once more, and fucked her through it until my balls tightened. "Gonna fill that black pussy with white cum," I warned. She pushed back hard. "Do it. Breed me with that giant cock."
I buried myself to the hilt and unloaded, thick ropes of cum pumping deep inside her. Pulse after pulse until it leaked out around my dick and down her thighs. I stayed inside her, grinding slow, letting every drop drain into that tight hole.
Maya looked back at me, eyes glassy and satisfied. "Same time tomorrow?" she asked, already squeezing my softening cock with her pussy.
I grinned and pulled out, watching my cum drip from her. "Bring that mouth ready. We're just getting started."
