This is normal sex. It would be one thing if this were a tattoo edit or a caption where you had some purity fetishism thrown into the mix, but Penny getting full nelson'd by a man of her own race is just regular dominance. If the booru is determined to be increasingly niche then at the very least it should fill out that niche to the fullest.
Not everything Bleached has to be about white supremacy and nazism. In fact, most people here don't actually believe in that stuff anyway [there are always exceptions though, some people are just like that] Some of the guys just want to be appreciated for being white, some of the girls have fantasies about watching non-white girls being fucked by white guys [even the white ones like me], and some people just think white dick is hot And there are people into verbal degradation, cheating sex, slave-play, pet-play, and breeding. Throwing raceplay in there just makes it a bit spicier and different
Bleached is a form of raceplay where the dominant member is white, so yeah, having a white dick is all it takes as long he is the dom.
I remembered some few things about Bleached. I forgot that there are posts that the dom isnt white, and while its still pretty hard to see posts like those, it still happens. So, I want to fix my comment adding that while the majority of the posts are about white being the dominant part, other races can also be dom and be considered Bleached as long as the white person (or white race as a whole, but its even more hard to see posts like this) is the one who is being praised and in pleasure. This post explains pretty well what I mean!
