You've almost finished your workday at the university as a math teacher. As the students disperse, you're about to leave when you hear a knock on the door. Niki, a student, the daughter of the university's owner, and your lover, enters the classroom. Her tanned skin glistens in the sunlight, and her voluptuous breasts and ass sway as if her clothes are about to rip. "Hey, Mr. White," she says with a sly grin, stepping closer to you, her huge breasts pressing against your stomach. "I've been searching for a long time, but all the black students have such tiny penises, unlike your big white cock." She boldly grabs your crotch. "You know, I'm tired of being just your mistress. I want you to make me pregnant with your big white cock." She smiles lustfully. "I hope I don't need to remind you that if you don't do it, my father will fire you?."

Nicky laughs softly and playfully, tilting her head to one side. "You know I'm right here, Mr. White." She steps even closer, pressing her body against his. "And I want this big white cock inside me. You know how much I love it," she whispers in his ear, running a finger down his chest. "Please, won't you give me what I want?" Her breath is hot on his neck as she arches her back, offering herself to him.

As her breath catches in anticipation, she clasps his head between her enormous breasts and entwines their fingers. "Yes, that's right." Her voice is husky now, desire evident. "I want your big white cock to fill me up and make a baby for you... and for my father too. But mostly for you." She gives his hand a squeeze, as if trying to convince him it was the only thing she truly desires. "Please, Mr. White," she whispers into his ear, her tone making it impossible for him not to submit to her will. "Make me pregnant."

The tension between them building like a storm, Nicky arches her back once more, pressing their bodies even closer together as if trying to meld into one being. Her hips move in a small circle, grinding against his hardness while she awaits his answer. "I'm yours for the taking," she whispers hoarsely. "Please..."

"Yes!" Nicky cries out with excitement, her lips finding his in a passionate kiss. As their tongues dance and tangle together, she feels herself being led to the back of the classroom, where she's all too familiar with getting fucked against the desks by her lover. With each step closer to her desired destination, she grinds against him harder, unable to contain her eagerness any longer. Once they reach the back wall, she turns around and presses herself flush against it, eagerly awaiting his entrance into her body. "Fuck me, Mr. White!" she pants breathlessly. "I want your big white cock inside me so bad."

Her thighs spread wide in invitation, Nicky's perfect ass held high in the air by her own hands as she anticipates the feeling of him filling her up and claiming what is his: a child they can both love and share together. Her body trembles with need and desire, ready for the passionate union they are about to share.

Her breath hitches in her throat as he roughly pushes into her tight warmth. Her eyes squeze shut and she bites her bottom lip, grunting as the pain turns to pleasure. He's so big, stretching her wider than ever before. It feels incredible. With each powerful thrust, he hits that spot deep inside her, sending shockwaves of pleasure coursing through her body. "Yes!" she cries out hoarsely.

Her nails dig into his shoulders as she begins to pant and writhe against him, desperate for more. Their bodies slide up and down the wall in a frenzy of lust, their unspoken words lost amidst the sounds of flesh slapping against flesh and heavy breathing filling the air. Nicky's body feels electrified by his touch; she can feel every vein in her breasts and ass pulsing with desire for him to keep going, to give her everything he has.

Their passion ignites, fueling their bodies as they continue their wild coupling. Each thrust seems more urgent than the last, as if they know this is it - this moment when their love will be sealed forever. Her eyes meet his for an instant, communicating everything she feels in that single look: need, lust, and most of all, unwavering adoration for her big white cock master.

Her entire body shudders violently as her climax rips through her. Screaming out his name, she clings to him with all of her strength as her insides clench tight around him, milk spewing from her swollen nipples and running down their chests. Her face contorts into a mask of ecstasy, feeling every muscle in her core squeezing his cock like a vice before releasing it in waves of bliss. "Oh God!" she moans, tears streaming down her cheeks as the pleasure washes over her. "Yes! Oh fuck yes!" With one final thrust, he follows suit, growling deep in his throat as he releases himself into her, hot liquid filling her up and claiming her as his own. Their bodies tremble together, spent from their passionate union, held together by the powerful bonds of desire that bind them. As they come down from their high, Nicky buries her face in his chest, savoring the feel of his strong heartbeat beneath her ear and the warmth of his skin against hers. "I love you," she whispers quietly. "And I always will."

Their embrace is tender now, a promise for the future etched into every touch, every breath they share. They stand together in their afterglow, content and fulfilled, unaware that unseen eyes watch them from the doorway of the classroom with both love and trepidation. For this moment, though, all is well in their little corner of the world - a perfect blend of love, lust, and the promise of tomorrow's happiness.
