A Scent of Heather (1980) (Better Quality)

Starts with a tense outdoor shot of some dude in a military cap—feels like a setup for something darker, but then it jumps to the real action. Two girls: one’s a stacked MILF with dark wavy hair and curves for days, the other’s a petite blonde with small tits but a tight little body. The blonde straddles a lean guy with messy brown hair, grinding on him while he plays with her tits. Then the MILF gets her turn—some older suit kneels between her legs and goes to town on her pussy while she’s perched on a desk. Doggy style follows, with the blonde on all fours getting pounded from behind. The camera gets right in there, so you see everything. Last shot’s the blonde getting her pussy licked while she lies back on the bed. Lighting’s dim but clear enough to see all the details.
