A Latina sucking a BBC (huge or otherwise) doesn’t really narrow it down much. As for the roses, I’m going to let you into a secret: you can skip ahead in porn videos to the bit where the actors begin to get really friendly - you don’t need to sit thru all of the bad acting and unoriginal dialogue unless you’re a masochist (or a student of independent cinema). So I’m unlikely to notice any roses.
Could it have been from any of the Blacked series or Blacks on Blondes (if she’d bleached her hair)?
