There used to be a huge series of videos, probably from early 2000's, with really attractive women on sybian machines, and at the end right when they're cumming, a guy would come up and cum in their mouth. I'm confused because I can't find anything anywhere aside from a few random studios that occasionally do that sort of thing. To be clear, it's not bondage vibes at all, it's just women enjoying themselves and getting cummed on.
