Was sorting through my files and stumbled upon some content kind of relevant to this thread. This camwhore (babyfaceforever aka babyfacecams) started streaming on chaturbate in 2016. She did some more explicit stuff (as you will see in the link) but I think spent most of her time in the public room just teasing and chatting. She must really love the smell and taste of her pussy because whether a teasing stream or a bate stream, she tries to conceal how she gets pussy juice on her fingers by rubbing it (and/or her toy if she is using one) and then brings it either directly, or after a short moment, up to her face and mouth.
She does this to some extent in most if not all of these videos but the best example is the first one I have titled "Sloppy". She is extremely wet and despite the poor resolution, you can often see a trail between her fingers or between her hand/fingers and face after they touch if you look closely. Maybe it was an inside joke with her top simps or she gets off on the secrecy but at one point, she has it all over the palm of both hands and cups her face, then slowly pulls them away to see how much it stuck.
