Tisícrocná vcela (1983)

One of the girls has long black hair and a tiny frame, almost doll-like, but with heavy natural tits that bounce hard when she rides her partner. They start with missionary, slow and grinding, her palms pressed flat on the other girl’s chest like she’s pinning her down emotionally. Switch to spooning after that, both of them slick and quiet, focused — you can hear the wet sounds clear. Camera stays tight, mostly close-ups on faces and pussies, no wide shots to ruin the mood. They’re not faking — the one on bottom actually arches and shudders when she comes. After, they switch to doggy, the top girl pulling hair and slapping her ass hard enough to leave marks. No talking, just breathing and the occasional moan. It’s raw, no music, just the two of them working through it like they’ve done this before.
