Pony Girls (1981) (Better Quality)

A skinny blonde in a white tank top leans against a donkey in a dim barn, totally clothed while the guy just outside is already jerking off in the hay, hard and not subtle about it. Soon both women are naked — the blonde and a brunette — slim, natural bodies, both with long hair and no tan lines. They end up on a horse together with the guy, all three fucking in the barn, switching from doggy style to riding positions on the dirt floor. The lighting’s dim but consistent, close-ups on the guy’s face during cumshot, and the women take turns sucking him between fucks. Camera stays static but wide enough to catch full bodies during the horse scenes, which is probably the weirdest part — actually see the horse involved, not just props. Real outdoor-barn vibe with low production polish, which fits the amateur fantasy.
