Porn star scene: black slave white master ... can&

Starts off with white guy on a horse with a black chick having a rope tied around her wristo stumbling along.
they end up in a cabin where he keeps her tied up.
he fucks her and it's awesome.
after he cums she manages to grab the letter and kills him.
then she stands above him and his cum is pushed out of her and onto his face
the end.
this is a legit scene, not amateur
thanks
