I have some very good advice that works very well, I have used them myself so I can vouch for them.
First: make sure she has a good time and enjoy herself. Second: plenty of alcohol.
Two very simple rules that has helped black men score with white girls and women since the prohobition in the 1920s (and long before that I might add)
If you can, talk to some black alpha male and set things up beforehand, that helps too (yes, personal experience about that too).
If you do the above, Im pretty sure your mom will be on her back, legs spread and a massive black cock fucking in and out of her.
this is a good son, and it does work to talk to a black alpha man before hand, it worked on my sister
