Context:
To start of, my girlfriend is not actually racist. She come's from a bit of a racist background, and her family is a little bit racist. Again, not the overtly racist kind. They try to be friends with black people and are externally semi-accepting, but they would never let their daughter date a black person. They probably definitely believe certain stereotypes and don't like black people a much as they do white people.

A little bit of this rubbed off on my girlfriend, since that is the only environment she has ever known. She has always been biased toward dating white men, and has never really swiped right on a black guy on Tinder. But, she's still a horny little freak and cannot deny her attraction when she sees tall, muscular black men in public. A few days ago, she saw a really attractive black man while she was out shopping, and she told me about it later. She was worried about making me upset.
We have a dom/sub relationship, and I have been opening her up sexually and developing her kinks over time. She loves making progress in this regard. I saw this as the perfect opportunity to do just that.

My girlfriend:

She's a pale Slavic girl with blue eyes and light brown hair. The perkiest set of almost C-cup breasts, a tight pussy that gets sloppy wet all the time, and a tiny waist that should not transition into her unreal butt. Her figure is incredible, and she's got a cute, innocent looking face to go with it. I promise I'm not exaggerating.

The Story:

So, later that night, I wrote her a little piece of erotica from her POV. Here it is:
Where do I begin? Yesterday. Yes. Let me tell you happened yesterday. Currently my boyfriend, and I are living apart... and while it is not the best, it is going well. I am his *cough* I mean daddy's submissive, so I do as he says. Well, I do my best. I am still being trained, so sometimes I fuck up... sometimes I have bad thoughts about other men... I wish I didn't. That's what happened yesterday. I had a bad thought. There was this tall and very attractive black manager at the clothing store I visited. I was very good in my interactions with him... but my mind did wander.

So, obviously I told daddy. I told daddy everything, because I am a good and honest sub. I thought he was going to be mad at me, but he did something very very surprising... and that is what this story is about. This story is about how daddy rewarded me to teach me that it's okay to have passing thoughts as long as my actions are perfectly good and respectful. Here's what happened the next day.I had to go back to the same store again to return a white t-shirt I had bought, except, this time I went alone.
Lo and behold, I ended up having to interact with the same tall, dark and handsome manager. He looked really good in his uniform! As per daddy's instructions I had to look extra pretty today, so I did! I wore my yoga pants that always gave me a wedgie and made my ass jiggle, and I wore a tight little croppie with no bra. So when I walked into the store, I immediately noticed him staring at me from behind the counter. I blushed and couldn't maintain eye contact with him."Back again so soon?" he said in his deep, masculine voice. My heart started beating fast immediately, because I was excited... I was excited to do exactly what daddy asked me to do. I gave him my cutest smile and pipped "Yes, sir :) I need to return this!" He smiled and helped me with the return process, occasionally eyeing me and making innocent small talk that felt just a tad bit flirtatious. I walked away and immediately found a semi-modest, but still sexy skirt to try on.

This was it. I took a deep breath and walked toward the fitting rooms... same as last time there was no one there. This was the perfect chance. I waved at the manager and said "Sir, is it alright if I go in and try this?" He said "No." with a serious face. I was caught off guard and my face dropped, and then he just burst out laughing. "Of course you can, cutie. Come on, the doors are locked today, but I'll unlock one for you." I playfully hit him and said "You're so mean!" and giggled. He led me to the door and unlocked it... and my heart started pounding. It was now or never. I stepped into the room and turned to the manager with the most innocent look I could. "S-sir" I stammered. "Could you please help me try this on?" I immediately looked to the ground. Fuck. I cannot believe I said that. Fuck. Why did daddy make me do this. The manager looked completely unfazed, but with a slight smile and said "Sure, it's our job to help our customers.".

"Turn around." My face was bright red, my heart was pounding and my pussy was throbbing. I was about to butt ass naked in front of another man... and this was daddy's reward for me. I had no idea what was about to happen.I turn around, and as I did I hear the door lock behind me. Suddenly, I felt the manager's strong black hands wrap around me as he pulled me into him, pressing my body against his. His right hand immediately covered my mouth and his left hand buried into my crotch, practically grabbing my pussy and pushing my ass back into his crotch. Fuck, I felt an incredible rush of adrenaline. He was so tall and big that I could not move. I felt small. I felt helpless. I could smell his musky sent as he leaned forward and growled into my ear... his lips grazing it... "Is this what you wanted little snow bunny? You're not the first white girl I have undressed in this dressing room... but you might just be the prettiest." I melted and almost moaned into his hand that was still covering my mouth as I felt his cock grow rock hard against my ass cheeks.

Fuck. I could tell that it was going to be big. His hand moved down from my mouth and wrapped around my throat, while his other hand slipped inside my yoga pants and my panties in one swift motion as he started playing with my pussy. I was almost embarrassed by how wet I already was. His cock was throbbing against my ass and the whole situation was just too much. Too fucking much. And then I thought about how this was daddy rewarding me and it just made me more desperate to be a good girl. "Fuck, I want your cock... I want your cock inside me right now."He let go of me and calmly said "Take off your pants and bend over." . I did as instructed while I heard his pants drop to the floor. I was so curious to turn around and look at his cock, but before I got the chance, he pounced.He grabbed my hips and pushed me down onto my knees, and he positioned himself behind me.
My pussy was aching with anticipation as I felt his thick black cock pressing against my dripping pussy.

"White girls are such pretty little sluts." I could see him in the mirror. His big muscular body. His glistening black skin. His smirk as he looked me in the eyes. Oh fuck. Right as we locked eyes, he shoves his entire length in me. He mercilessly pressed his balls against my body as my pussy engulfed his entire cock. I moaned like a whore as I watched this stranger lustfully take my body from behind. I loved it. I loved it so much. I squirmed under him. I screamed as he fucked me deep and hard. He grabbed my hair and pulled me back, arching my back and turning me into an even bigger whore.Fuck. I was being used. This was my punishment. This was my punishment for finding this man attractive and I was so fucking happy to be punished. Anything for my daddy… wait no. “Passing thoughts are okay… this is your reward for acting good.” That’s right. I was good. This is my reward. The thought of being rewarded like this drove me crazy.

"FUCK ME! FUCK ME HARDER!". I knew there was no one in the store, so I felt no shame. I wanted him to cum in my pussy. I wanted it all. I wanted him to fill me up. He pulled out of me and quickly flipped me over, my back was now on the floor. Then, he grabbed my legs and lifted them over his shoulder. Oh my god. I felt drunk with horniness as he shoved his black cock inside me. Wow. His cock felt even better, because of the way it curved down. Suddenly, he leaned over me and started choking me with both his hands as... he... he started thrusting... Oh fuck.

His powerful body tensed up and he started fucking me so hard that I swear I could feel every inch of his thick dick plunging deep into my pussy. I could not move and I could not look away as this powerful black man violently pounded my pussy. My mind wandered to what my racist father would think if he saw me right now. Not only was I already the property of a mixed brown man, but now I was being used like a whore by this black man. Imagining his anger strangely turned me on even more. I started moving my hips and squeezing my pussy around his big black cock out of spite. And this pushed him over the edge. He slammed his massive cock deep inside me and held me still as he started shooting his load deep inside me. I could feel his cum filling my womb as he continued to pump his sperm into me until he finally collapsed on top of me.

The Aftermath:

I gave her instructions to read the story, and then masturbate herself to as many orgasms as she wanted. She was only allowed to fantasize about black cock, and I linked a few interracial porn videos for her to use as well.

She found it insanely hot. She came 4 times thinking only about black cock sliding inside her beautiful pale body. She told me that her brain protested, and that it was not easy, but she was eventually so horny that all she could think about was black men. It gets better.

The next night, she went out of her way to ask me for permission to masturbate. I said sure, but only if she fantasized about black cock. She came 4 times again, but this time she imagined herself being fucked by a black man on her racist parents bed. She said she has never felt so turned on by the idea of black men before. Hahahaha, new kink unlocked. It'll be fun to swing with another interracial couple, just to fuck every last little bit of "racism" out of her. DM's open . ;)

This was a real story, but ladies/couples, if you're interested in some customized erotica, let me know. Curious to see if anybody is interested.
