Search for Whipping Marks on a Black Woman Skin (CLOSED) (CLOSED)

Dear Guys,

i didnt know if someone knows a working Product or can create one. 

I search for Whipping Marks on a Black Woman Skin (mostly Torso and legs). 
I tryed "Sound Punishment" from Renderotica but that looks only good on white
skin. 
If someone could help it would be really nice.

Thanks

change the color to darker brown, nearly black, that will doe
