Professor Elena Vargas sat in her empty classroom grading papers when Jamal walked in and shut the door. The tall Black student dropped a flash drive on her desk without a word. Elena clicked it open and felt her stomach drop. There she was on screen, legs spread in her office chair, fingering her shaved pussy while moaning another man's name. The hidden camera had caught everything from the angle of the bookshelf.
"You failed me on purpose, Mrs. Vargas," Jamal said, his voice low and steady. "I got the real test answers from your computer last week. You want this video to stay between us, you do what I say."
Elena swallowed hard. "Jamal, this is insane. I'm married. You're a student."
He unzipped his jeans and pulled out his thick black cock, already half-hard and heavy. "Strip. Now. Or I send this to your husband and the dean."
Her hands shook as she unbuttoned her blouse. She slipped out of her bra, letting her full tits bounce free. Jamal stroked himself while he watched. "Faster, teacher. I want to see that married white pussy."
Elena pushed her skirt and panties down. She stood naked in front of him, nipples tight, pussy already slick from the mix of fear and unwanted heat. Jamal stepped close and grabbed one breast, squeezing hard. "On your knees."
She dropped. His cock was massive, veined and dark, the head glistening. Elena opened her mouth and he shoved in deep, stretching her lips. He fucked her face without mercy, one hand gripping her hair, balls slapping her chin. Spit ran down her neck onto her tits.
"Look at you, sucking Black student dick like a whore," he growled. "Deeper."
Elena gagged but took more, tears in her eyes. Jamal pulled out and bent her over the desk. He slapped her ass hard, then lined up and drove his cock into her tight pussy in one thrust. Elena cried out. He was so much bigger than her husband. He pounded her relentlessly, the desk creaking, her tits mashed against papers.
"You come on this Black dick or the video goes out," he ordered. His fingers found her clit and rubbed fast. Elena's body betrayed her. She came hard, pussy clenching around him, juices dripping down her thighs. Jamal kept fucking through her orgasm until he pulled out and painted her ass and lower back with thick ropes of cum.
He made her lick him clean. Then he told her the rules: every Tuesday after class she belonged to him. If she refused, the video spread.
The next week he took her in the faculty bathroom. Elena bent over the sink while Jamal fucked her from behind, one hand over her mouth to muffle her moans. He made her watch in the mirror as his black cock disappeared into her stretched white pussy. "Say you love Black dick," he demanded.
"I love it," she gasped, coming again.
He started pushing further. One night he showed up at her house when her husband was out of town. Elena let him in wearing only a robe. Jamal bent her over the kitchen counter and fucked her ass for the first time, stretching her tight hole while she bit her arm to stay quiet. Cum leaked out of her for hours after.
Weeks passed. Elena stopped fighting. She started wearing shorter skirts to class, no panties, knowing he'd notice. After one lecture he followed her to her car and fucked her in the backseat, windows fogged, her riding him reverse so he could watch her ass bounce on his thick shaft.
The blackmail never ended, but the sex became something darker and hotter. Jamal would text her instructions: "Wear the plug to class. Send proof." Elena obeyed, sending photos of her plugged ass under her pencil skirt. He rewarded her by eating her pussy until she screamed, then fucking her senseless.
One afternoon he brought a friend. Elena took two Black cocks at once, one in her mouth and one in her pussy, spit-roasted on her own living room floor. Cum filled her from both ends. She swallowed what she could and let the rest drip down her chin while Jamal filmed a new video, this one willing.
By semester's end Elena was his. She failed him on paper but passed him in private, on her knees or bent over whatever surface he chose. The original video stayed hidden, replaced by dozens of new ones she helped create. Every time he called her "teacher" while stretching her holes, she came harder than she ever had before.
Jamal graduated. Elena still met him once a week at a cheap motel off campus. She arrived already wet, stripped fast, and begged for his Black cock like the blackmail had never stopped. It hadn't. It had simply become the thing that kept her coming back for more.
