Watching until every last person cleared the lecture hall was painful, the seconds stretching as footsteps echoed away. Until at last they were left alone in heavy silence. Tiana was on pins and needles, her heart hammering wildly in her chest, breath shallow and ragged.

Please don't tell my mom. It's just a fantasy.

She immediately wanted to beg, the plea rising in her throat like bile, but Matt beat her to the punch and spoke first.

His words surprised her. The beginning sounded right. She expected the yelling. The last question, however...

"Explain yourself. What is your fucking problem? Are you trying to get your mother to leave me?" he bellowed, then adjusted the massive anaconda in his pants uncomfortably with a frustrated grunt.

Only then did Tiana look up, her eyes locking on the obvious tent, a wicked spark igniting in her core.

A hard dick meant a horny professor daddy. Right? She licked her lips slowly, a guilt-ridden, sinful resolve settling in her pussy.

In for a penny, in for a pound(ing)... straight from Matt's big, fat dick.

"Is there a possibility of that happening, Professor?" Tiana asked slyly, her voice dripping with seduction as she seamlessly got up from her seat.

Matt gulped as she bent over the lecture hall bench in front of him, her mini skirt hiking up to reveal her bare ass cheeks.

Unlike in the fantasy on the page, Tiana wasn't wearing pants or panties for that matter.

The little whore had on that tiny mini skirt with nothing underneath. Her pussy lips peeked out between her legs, glistening with wetness. Matt knew there would be no panties, because he had been staring at that same naked, pink pussy all month.

All while pretending not to notice her flashing him. Her pussy tormented his dreams, the sight now making his mouth water despite himself.

"Get up, Tiana. Stop it. You've had your fun. Now stop flashing your daddy, I mean professor daddy, I mean me, your professor and mother's husband. Stop showing me your pussy. For fuck's sake wear a damn bra next time you come to class too," Matt growled, his voice thick with strained control, a low groan escaping as he fought the urge to reach out and spank her ass.

No sooner had Matt finished the sentence than he bit into his fist to muffle another deep, guttural moan. Tiana had taken the time to start popping the buttons of her blouse one by one, deliberately slow, revealing her creamy cleavage inch by inch. Matt's dick hardened and throbbed even more, jumping in his pants as her giant knockers bounced free.

Tiana's jugs came complete with stiff pink nipples that begged to be twisted and sucked. The sight sent a jolt straight to his balls.

"I'm going to hell. I'm getting another divorce, aren't I?" he said with a resigned sigh.

His hand went straight to his aching dick, palming it roughly through the fabric, as precum leaked onto and stained his suit pants.

"Fuck, no. Tiana, fucking stop. Anyone could walk in here," Matt begged hoarsely, his breath coming in pants.

He told himself to simply leave, but he couldn't stop drooling over her tits, his eyes glued to the heaving globes. Matt imagined burying his face between them. After that, he was a goner.

"What's the matter, Professor daddy? You had no problem having an affair with my mom and ending her twenty year marriage," Tiana taunted, too turned on to turn back now.

Her pussy clenched with need as she lifted her skirt higher to flash Matt her round, plump ass. She shook it at him teasingly.

Her ass cheeks jiggled enticingly with a soft slap. Then she grabbed her heavy tits and jiggled them at him too, moaning softly as her nipples hardened further in the cool air.

"Your mom and I fell in love. She was unhappy with your dad. Shit happens. I'm sorry we hurt you. Please, God, stop," Matt begged, the composed, distinguished professor retreating as the recently married, former player panicked. "I just want to get to know you. Is that so bad? Come on, put your-Jesus, you have nice tits and fuck, that's a big ass," he admitted breathlessly, allowing himself to peek from between his fingers, his cock throbbing painfully while watching her performance.

"I'd like to get to know you too. So would my pussy. Let's start with you fucking it really, really hard, Professor daddy," Tiana taunted with an innocent pout.

Her hands trembled slightly from the adrenaline and fear as she reached for his belt buckle. Tiana's fingers fumbled, but she was determined to follow through. She brushed the heat of his bulge.

If he shut her down now, she was toast. He'd tell on her, and her mom would hate her forever. If, on the other hand, they got in one quick (not so quick) hard fuck... everybody wins. He would have something on her and she something on him.

"Get the fuck away from my dick. What the fuck are you doing?" Matt cried out, his voice cracking,

He knew perfectly well where this was heading, his hips betraying him by bucking slightly into her touch, but he yelled anyway. Just in case that somehow woke him from this pleasurable nightmare.

Matt knew he was screwed the moment he allowed her to unbuckle his belt and unzip his pants. She freed his thick, veined cock easily. It sprang out heavy and leaking precum, the scent of his musk mixing with her arousal in the air.

"Relax. One little fuck never killed anyone. It's this or I tell my mom you seduced me and fucked me while I was drunk. What's it going to be, Professor daddy?" Tiana asked boldly, one hand on her hip in defiance while the other wrapped around Matt's throbbing dick.

She stroked it firmly while the veins pulsated hotly under her palm, a drop of pre-cum smearing her fingers.

Helen would one hundred percent believe Matt over Tiana and with good reason. Tiana was a slut, her reputation whispered in family circles and her mother knew it. The good professor didn't though, or at least hadn't acknowledged it until now.

"This is so fucked up. Please don't say that to my new wife," Matt begged, his voice wavering as he watched himself justify what was about to happen.

His resolve to resist the young, tight, wet, warm pussy before him and wait on his wife crumbled as Tiana sank down onto her knees.

Tiana's hot breath teased his tip, making it twitch. That was the last straw. Matt was done being toyed with. If they were going to fuck anyway, it would be on his terms. The bitch would get a brutal, dominating fuck that would allow him to reclaim control.

"Get the fuck up," he roared suddenly, grabbing onto Tiana's pigtails and yanking her roughly back to her feet with a sharp tug.

Tiana yelped, surprised that the professor had this side to him. The sting of pain shot straight to her clit.

Tiana opened her mouth to beg for forgiveness and mercy, a whimper escaping her lips, but Matt didn't give her the chance to speak.

He slapped her ass hard repeatedly, the cracks echoing loudly in the hall as her cheeks turned red.

A sharp gasp tore from her throat. No sassy comeback. This gave Matt a sense of achievement and the boost of confidence to shove her face-first down onto the lecture bench before them. Her tits were squished against the cool wood. A muffled moan left Tiana. Too far gone to stop now, Matt jammed his hand between Tiana's legs, fingers roughly parting her slick folds.

"Fucking whore. How much longer am I supposed to resist your teasing, Tiana? Do you know what happens to little girls who beg to fuck? They get their pussies used until it hurts, Tiana," Matt yelled into Tiana's ear, his harsh breath sending shivers down her spine.

He yanked back harder on her pigtails, pulling her head up while rubbing furiously at her wet folds. His fingers, slick with her juices, withdrew from her folds and smacked down on her clit roughly.

"About fucking time," Tiana cooed breathlessly, her back arching as the wet, squelching sounds of his rubbing her clit filled the air. "I was starting to think you weren't looking at me. That I imagined your glances between my legs and at my tits, Professor daddy," she purred, her voice turning into a gasp as he pinched her clit hard.

Fuck waiting for Helen. Fuck losing his marriage because of this whiny, little bitch teasing him all the time while claiming she hated his guts in front of her mom. Matt was done pretending he didn't notice, the pent up frustration boiling over. His dick was fucking that tight pussy. Period. The thought of Helen faded to the back of his mind as lust took over, his cock demanding satisfaction.

"You better not be a fucking virgin. Too much fucking drama," Matt growled low in his throat, fisting his dick and coating it thickly with Tiana's dripping juices.

The slick sound was obscene to his ears as he pressed the fat tip of his dick to her entrance, teasing her hole with shallow prods that made her whine.

Tiana giggled like that was the funniest thing she had ever heard. Her laugh was breathy and taunting as her pussy sucked greedily on the head of his dick.

"Fucking bitch. You want dick? You're getting it today," Matt snapped, his voice dark with rage and desire.

He jammed his dick into her cunt with one brutal thrust, bottoming out inside her with a satisfied groan. Tiana's pussy walls clenched around him like a vice.

She yelped sharply, her whole body quivering and shuddering beneath the force of Matt's big, powerful body slamming into her smaller one.

The bench creaked under the impact. Pain mixed with pleasure to form a delicious burn between their joined bodies.

Then the little bitch started laughing again, breathless and triumphant, and said with a gasp, "Yes, Professor daddy. Give my slutty pussy your big dick. Don't be gentle."

He grabbed onto her ass cheeks roughly, fingers digging in hard enough to leave bruises as he spread them wide, exposing her completely, and snarled, "I fucking won't."

Then he started pounding into the nightmare that was his stepdaughter relentlessly, fucking her hard and rough, his hips slamming forward with punishing force, the air filling with the rhythmic slap of skin on skin, her juices squelching around his cock.

"Professor, daddy, fuck yes," Tiana wailed loudly, her voice echoing off the walls.

Was it fucked up that she liked the fact that she was being railed senseless in a public setting? The risk heightened every thrust.

Her revenge against her mom, on her dad's behalf, was complete. Seducing her mom's new husband into claiming her in the dirtiest way was the ultimate betrayal. Getting plowed by Matt was amazing. His cock stretched her pussy wide, hitting spots that made stars burst behind her eyes.

"Do you even pay attention in my class at all? You're fucking failing," Matt roared, his voice thundering over her cries.

Where the fuck did that come from? That was the least of Matt's problems as sweat dripped down his back.

He was fucking his stepdaughter in a lecture hall, the door unlocked, anyone could walk in and see the depraved way in which her was recking her. Damn it, he was betraying yet another wife for younger pussy. The guilt twisted in his gut like a knife, but bitchy Tiana deserved it for her endless teasing. The harder he slammed into Tiana, the better he felt, each thrust a release of pent-up rage and horniness. He punished her pussy while getting sweet relief for his cock and it was heavenly. The tight heat of her pussy enveloped him perfectly. When last had he fucked someone her age?

"Fucking tight pussy," he ranted over Tiana's moans and outcries, hammering away at her cunt with brutal snaps of his hips.

The scent of their sweat and sex was thick in the air.

"There's no point in studying when I'm getting fucked by my professor. Fuck me harder, Professor daddy. Fuck, that's a big dick. No wonder mom cheated on dad. Damn it, that's so worth it," Tiana cooed, gasping but still smirking smugly as she got railed from behind.

Her body jolted from the impact. Her tits were firmly squished against the cool wood beneath her. The friction rubbed her nipples raw. Matt's balls smacked against her ass with wet thwacks. He was a rough, brutal fuck, but Tiana loved it. Her arousal dripping down her thighs was the proof.

"You really hate me, don't you? Can't we just get along? I fucking love your mom, damn it. Fuck, one whole month without pussy!" Matt yelled, his words echoing off the empty walls of the lecture hall, frustration and lust warring in his chest. "I fucking needed this."

How many times had he come in here and acted like he wasn't horny out of his mind, lecturing while his cock strained to be inside Tiana?

Fuck, he was only human. Thrust. Thrust. Thrust. He had to have that pussy. The need was overwhelming. Damn her cunt for being so tight and warm, and gripping him like it was made for him.

Tiana was no virgin. Her body took the pounding like a perfect slut. Her hips pushing back to meet his with eager slaps. Matt found a small amount of solace in this, as his conscience reared its ugly head.

"Harder. Harder. Harder, damn it. I'm not my prude mom," Tiana screamed, her voice raunchy and demanding. "Use that dick and fuck my slutty pussy silly."

This turned Matt on more, the comparison between the two women fueling the fire in his loins. His brain switched off completely, animal instinct taking over. His dick pummeled in and out of Tiana, the wet sounds all consuming, while he forgot where they were and even that he was married.

All he could think about was slipping both hands onto the whore's throat and fucking her like a ragdoll. Deeper. Harder. He wanted to be buried inside her over and over, using her body for his pleasure. Nothing else mattered but putting the bitch in her place.

"Yes, Yes, Yes, YES. So Good. Just like that. Just like fucking that, daddy," Tiana begged, screaming her throat hoarse, her voice breaking into sobs of ecstasy. "Use me. Punish me, daddy. Doesn't my spoiled, rude pussy deserve it, Professor daddy?"

How much harder did Matt have to plow the bitch before she shut her fucking mouth? The taunts only made him rougher, his hands tightening their hold on her throat.

"Fucking shut up and take it, you spoiled slut. We are going to get along when we get home, aren't we, baby girl?" Matt demanded, as he gave in completely, letting his inner beast go wild screwing her, choking her as he rammed deeper into her.

Hatred fueled their passionate fuck as Tiana chocked on air. They were a mess of sweat drenched bodies, gasps, moans, and cum. Orgasmic bliss was not far off now.

"Cuming. Cuming. Cuming for you, daddy," Tiana whimpered beneath Matt, her voice muffled against the wood.

Only then did his brain turn back on, guilt crashing over him in waves. Her little form writhed and spasmed beneath his, her pussy convulsing wildly. It hit like a ton of bricks. He was married. Fucking his step daughter.

Still, hs dick could not be reasoned with as his balls tightened. The orgasm was too close. His dick wouldn't stop plowing her pussy, the sensation of her tight walls milking his cock too addictive. He was just so horny, the month of deprivation making him a savage, primitive creature.

Stop. Stop. Stop. The voices in his head told him. Instead, his now aching dick fucked harder into his wife's child, chasing his own release.

"That's it, baby. Cum for your Professor daddy. Next time you take one of my classes, you'll fucking pay attention and study. Won't you, you little whore?" he rasped, cum flooding his dick.

He was moments away from filling her cunt with his semen. What the fuck was he thinking? Another class? Matt would rather cut his heart out than get stuck with her in his lectures for another semester.

Fucking pull out. The bitch might not be on birth control, Matt panicked.

Matt clamped a hand over Tiana's mouth as she screamed blue murder, her muffled cries vibrating against his palm. Too late to ask her now. Her cunt was crushing his dick so hard that there was no avoiding it. He was about to cream pie his stepdaughter. The thought was both horrifying and thrilling.

"Are you on birth control?" he choked out anyway, his voice strained as he fought the inevitable.

Tiana, slut that she was, was in fact on the pill, but mischief sparkled in her eyes.

"No," she said with a breathy giggle, her body still shaking against Matt's as she looked back at him over her shoulder. "Give your wife's kid a kid, daddy."

Matt yanked his dick out of Tiana's still cuming cunt, painful as it was (the sudden emptiness making her moan in protest).

"Fuck. Son of a bitch," Matt cursed as his dick ached, but he had to get away.

"Kidding. God, lighten up," Tiana murmured.

He stumbled away from her, his cock throbbing in defiance. Voices could be heard outside the lecture hall, muffled chatter growing louder. Students were gathering for a lecture. They were about to get caught in a very compromising position.

"Fuck," Matt cursed under his breath, then hastily bent down to pick up his pants.

His semi hard dick was still spitting out ropes of cum onto the floor with wet splats.

He knew he was making a mess, the sticky fluid pooling, but his mind wasn't working. It was fogged over with post orgasm bliss.

He panicked, looking on while Tiana clung to the bench. She held on for dear life as she came down from her very lengthy high, her body trembling, soft whimpers escaping.

For just a second, Matt admired his handiwork. His dick made the nineteen year old bitch cum that hard.

"Next time I come to class, we'll fuck in your office after. This is too risky," she announced breathlessly, now convinced she needed more of Matt's fantastic dick, the ache already building again between her legs.

"There won't be a n-n, fuck. Never again. Stay the fuck away from me," Matt demanded, but his aching dick was still cuming for Tiana's pussy, twitching at the thought. "Fucking make it stop," he called down to his dick in frustration. "Get dressed. We have to leave," he said to Tiana, stuffing his dick into his pants once it finally stopped cuming.

The fabric of his pants chafed his sensitive dick, making him wince.

The double doors pushed open with a creak. Matt's heart stopped. He froze in terror. Tiana was unfazed.

"First say you'll keep fucking me," Tiana challenged defiantly, shaking her tits at Matt, the globes bouncing enticingly.

He did love those fucking tits. The way they heaved, pink nipples still hard, called out to the horny teenager in him. He wanted to suck on her nipples, fuck those jugs, cum all over them, maul them, the works.

Fuck. No. If someone caught him like this with a student, his job, his wife, he would lose everything. The thought made his stomach drop. He hastily caved.

"Fine," he hissed under his breath, desperation to save face winning out. "Just fucking pull down your skirt," he said, advancing on her, his heart still pounding mercilessly.

A fresh bead of sweat dripped on his brow as he feared getting caught, the voices growing closer.

He hurriedly helped her get dressed, his hands shaking as he buttoned her blouse over her tits, brushing her nipples accidentally and making her moan softly.

"Please don't tell your mom I fucked you," he pleaded, his voice low and broken.

"Well, you do have an impressive, big dick. I bet it can go for hours. As long as it's pleasing my pussy, I promise to study for all your lectures in the future, professor. Every last one. Mum's the word," Tiana said with a coy wink, zipping her mouth closed with a dramatic gesture.

A twinkle in her eye promised more trouble, but Matt had no time to think about that as students flooded the lecture hall. He grabbed her hand and hurriedly rushed her outside.

Despite intending to renege on the deal, Matt grew restless when Helen could not make it to see him time and again. Not three days later, he buried his dick in his stepdaughter again.

This continued for the next few months, each encounter rougher than the last. They snuck into his office after lectures for quick, brutal fucks that left them both breathless. The new arrangement worked for them both. Somehow Tiana even passed the class.

To Matt, it was a naughty, pleasurable fling that reminded him of his youth. The thrill of fucking a forbidden pussy made him feel alive again. Tiana, on the other hand, soon fancied herself in love. Her heart twisted with possessiveness every time Helen called.

But a deal was a deal. When the semester was over, she went home and played nice with her stepdaddy. She smiled sweetly at family dinners while her pussy ached for his dick. Everything was turning out in Matt's favour.

Matt could barely look Helen in the eye when he and Tiana went home, guilt eating at him. He wined, dined and fucked his wife constantly to make up for the infidelity, pounding into her with desperate vigor. All this special attention he was showering Helen with made Tiana green with envy.

She fisted her sheets as she heard their moans through the walls at night, but she kept the peace, biding her time. She made no move to try and start things up again, her restraint a calculated play. A relieved Matt thought he was in the clear. The fleeting affair was a secret he would take to his grave.

Until the next semester rolled around. Lo and behold, who should he find, front and center in his very first lecture? None other than a braless Tiana, her nipples poking through her shirt teasingly.

"What the fuck are you doing here?" Matt hissed, breaking out into a cold sweat once he reached her, his voice a whisper shout as students filed in around them.

"Keeping my promise. I changed my major to Mathematics this morning. I pre-studied for class and everything. See?" Tiana said with a coy smirk, spreading her legs at the same time she opened her textbook to show Matt her highlights, her bare pussy flashing him under the desk, already wet and ready. "I'm going to study for every last lecture and make you proud, Professor daddy. I hope you keep your word too."

It took Matt a second to recall her wording all those months ago now while he was horny out of his mind.

As long as it's pleasing my pussy, I promise to study for all your lectures in the future.

That was also when she promised not to tell Helen about them fucking. Matt took the hint. The little bitch wanted her cunt railed... for the next four years... by him.

It wasn't a request or suggestion. He could do nothing but comply, lest she opened her mouth and blabbed. Matt hated the little bitch, but his dick sure didn't. It was hardening in his pants in anticipation as he stared at her tits.

"My office after class. With any luck, I'll fuck you to death," he said with a snarl, giving in far too easily, the weak man that he was.
