Onsen anma geisha (1968)

Starts with two skinny Asian girls in full geisha getup, sitting on the floor in some kind of tea room. One’s got her hair in a tight bun, the other’s got long straight black hair down her back. They’re just talking at first, but then the bun girl starts running her fingers through the other one’s hair and tracing her face like she’s memorizing it. No full-on making out yet, but the way she cups her cheek and leans in slow is hotter than most straight-up sex scenes. Later they’re eating together—sake, low table, sliding doors—still in those thin robes that keep slipping off their shoulders. You can see the outline of their small tits when the light hits just right. Camera stays close, so every little sigh and bite of food feels intimate. Only downside is it’s all teasing; no actual fucking, but the way they look at each other makes you wish they’d just rip the robes off already.
