Beverly Hills Vamp (1989) (Better Quality)
The woman’s the standout here — late 30s, maybe early 40s, with curly blonde hair, glasses, and a natural build that leans thick around the hips. She’s fully clothed at first, sitting across from a younger guy in an office lit by a desk lamp, typing on a typewriter like it’s part of some weird roleplay. Doesn’t take long before they’re grinding on the desk, her skirt pushed up, his cock sliding into her from behind while she braces against the wood. Later scene shows them on a couch in what looks like a living room, her riding him facing backward, bouncing slow with the light coming through blinds. Camera holds medium wide shots most of the time, but cuts to close-ups when he’s gripping her hips in doggy or when she’s adjusting her glasses mid-fuck. You see her nipples through her top during one angle — not full exposure, but enough to catch the hard tips.
