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 playfully. "Oh, Mr. White! You really don't know me very well, do you? I thought we were beyond that. Besides, haven't we been sneaking around for long enough? Let's just make this official. My father won't care as long as you keep teaching well and I have your baby." She takes off her shirt, revealing her massive breasts with their enormous areolas and nipples. "Come on, don't tell me you can resist this?"

I smile up at you as you look down at my breasts. "You like? My father is part black too, you know." I wink playfully and take a step closer to you. "So what do you say? Will you give me your big white cock and make me pregnant?"

I grin up at you, delighted by your new nickname. "Daddy," I purr as I wrap my soft hands around your cock through your pants. "You're big and hard for me." With a lustful groan, I pull down your zipper, freeing your erection from its confines. My fingers wrap around the thick shaft of your cock, guiding it towards my wet, eager opening. "Now show me what you can do with that big white cock," I whisper seductively.

I close my eyes and arch my back, moaning softly as you slowly push inside me. The feeling of being filled by your enormous cock is overwhelming, but in the best possible way. "Ohhh Daddy..." I whimper breathlessly. "Don't stop...give it to me hard." My fingers dig into your shoulders as I begin to rock my hips back and forth against you, taking every inch of you deep inside.

Ahhhh! Your forceful thrusts drive me wild with desire! "Yes, Daddy!" I moan, gripping the back of a chair for support as my hips rock in rhythm with yours. The sensation of your thick cock stretching me to my limit is almost unbearable, but I don't want you to stop. "Faster! Harder!" I cry out, arching my back and meeting every thrust with a grind of my own. My breasts bounce violently as I lose control in this passionate coupling.

My breath comes in ragged gasps as waves of pleasure wash over me. I can feel your big white cock throbbing inside me, preparing to release your seed deep within my womb. "Ohhhh God!" I groan, my entire body tensing as an intense orgasm overtakes me.

"I'm... I'm c-coming too!" I manage to choke out before collapsing bonelessly against you. My pussy clenches rhythmically around your softening cock as I feel your hot seed shoot deep into my core, marking our joining for all time.

"Mmmm... yes please, Daddy." I purr seductively, licking my lips. "I want your big white cock to fill me up until you make another baby inside of me." My hands slide down to grip at his ass, urging him closer again as I lean in and plants a soft kiss on his neck.

My nipples are already hard from the sensation of being filled so deeply earlier, and I arch my back once more, presenting myself eagerly to him. "Take me again," I whisper, the words shivering through my body as anticipation for what he will do next courses through me like wildfire.

I part my lips and close my eyes as I bring your heavy balls towards my face. My tongue darts out to tease them before gently lapping at the soft skin. A sharp inhale escapes me as I take one into my mouth, sucking and licking until it's perfectly clean. I repeat the action with the other ball, making sure not to miss a single drop of your musky scent.

When they're both sparkling from my attentions, I look up at you with pleading eyes. "Is that good enough for Daddy?" I ask breathlessly, already yearning for more of your hard cock inside me. My hands reach down to stroke and squeeze at my own breasts, teasing myself as I wait for your permission to continue our heated encounter.

Gasping for air, I try to pull away but your grip on my hair is unrelenting. My world is reduced to the hard length of your cock pressed against my throat and the weight of it as you force me down over and over again. My vision begins to blur from the pain and lack of oxygen, but I can still feel everything so acutely: your hot skin, your stubble scratching at my chin, your powerful thrusts that send shockwaves through my entire body.

As you continue to violate me in this way, my cries muffle into helpless moans and gasps. A flush of shame mixes with desire as I realize how truly out of control I am under your dominance. My fingers dig into the desk beneath me for purchase, my nails curling into the wood as I struggle to endure each relentless thrust.

But deep down, I know that this is what I want. I crave your big white cock and its brutal, merciless possession of me. I belong to you, Daddy, body and soul...and with each passing second, it only gets harder for me not to admit how right that feels.
