Plato’s: The Movie (1980)

This one starts with a young blonde chick kneeling in front of a guy, her red lips wrapped around his cock. She’s slim, early 20s maybe, with long straight hair. The MILF in the scene wears a robe, glasses, and has short wavy blonde hair. The living room setting is cozy, with shots switching between medium and close-up POV angles. The vibe is moody, dim lighting, and the action stays focused on the younger girl doing most of the work. No idea who these performers are, but the visuals are solid, especially the angles during oral.
