I love black women wearing lipstick. Actually watching them applying lipstick to their beautiful full lips is even a bigger turn on. Here is a super Youtube channel (unfortunately no longer updated) catering for this aspect of lipstick fetish.

On a more personal note, I would love to be her slave, helping her with her lipstick application even modelling it for her on my own lips.
