The Fifth Musketeer (1979)

One of the girls in the tub has big natural tits and she’s the first to get fucked. They’re all slim brunettes with long hair, totally nude, splashing around like it’s a bath party at a 17th-century estate. A young guy with curly brown hair shows up later — no shirt, kind of scrawny — and gets blown by one of the maids right in the doorway. The older gray-haired guy in a garden just watches, doesn’t do anything on camera. Most of the sex happens in the bedroom: one girl rides the young dude facing away, another sucks his dick while he’s lying down, then they switch to doggy style against the bed. Camera sticks close during the blowjobs, especially when he’s jerking off over her face. Background has stone walls and old-timey vibes but no costumes, just modern sex in a faux-historical location.
