There's this old Doctor Adventures scene with Gianna Michaels. The name of the scene is "Major Cleavage". I always remember this scene because the male Nik (I won't be disrespectful) who used to work on Brazzers for a while back then, he was never my favorite male performer. Gianna let him have it in that scene, at one point she's bent over the table and he's slow stroking it (it's dead quiet at this point) she looks back and says, "what the fuck is this" Lol.
