In high school the most 'popular' girl in my class was dating a black guy. She was the generic blond barbie girl who played sports and had a fat ass. I didn't actually care about race and stuff at all, other than funny racist pictures I saw on 4chan. Her black boyfriend was ugly (even by black standards) and not very intelligent.
Since she was popular and all she was sometimes the topic of discussion in my friend group. One time we were discussing the popular girl and there was also a girl hanging out with us who I had a crush on. My crush very adamantly defended the popular girl's boyfriend, saying he was confident, funny, athletic and black. She seriously mentioned him being 'black' as a positive quality. Hearing this made me really hard and when I got home I for the first time intentionally sought out interracial porn and got hooked on it. Through this I also discovered cuckolding and BNWO stuff.
The popular girl is dating a white guy now and my crush came out as a lesbian, so me still being really into this stuff is like a weird artifact of their high school past.
