Kusa-meikyû (1979)

Starts with this skinny Asian chick in a full kimono, hair pulled back tight, getting her sleeves yanked off by a white girl with long blonde hair and sleeve tats. The tat girl’s got that aggressive vibe, shoving the Asian one down on the tatami and straddling her before you even see any skin. Then it cuts to the Asian chick standing in the hallway, kimono half off, holding rope like she’s about to get tied or tie someone else—turns out it’s her. Next shot she’s outside in the garden, kimono open, rope already biting into her tits, looking straight at the camera like she’s daring you to touch her. Back inside they do the full kinbaku thing—thick black rope criss-crossing her chest, wrapping her thighs, pulling her arms behind her back so tight her tits pop out. The blonde circles her, licking her neck, then drops to her knees and starts eating her out while the Asian girl’s still standing, rope digging into her skin. Last shot they’re on the futon, Asian girl on her back, legs spread, blonde face buried between them, fingers working her clit while the rope keeps her from moving. Lighting’s dim, all shadows and warm tones, so every rope mark and every lick stands out. No dick, just two girls, rope, and a lot of saliva.
