Since im racist, the answer to the why is simple: They are niggers. Ergo, they have low impulse control and high libido's, so they take what they want, no matter how young they are or what morality says.
I also get the double-wammy arousal because i view them as real life orks, or like a sentient beast that can impregnate them, so it makes it extra dangerous that they can be ruined forever by birthing black spawn before they even should be dating, let alone getting fucked.

Mostly focus on the seduction angle though, like the black guy uses base cunning, like blackmail or coercion etc to both get them alone ang get in their panties.
