Shinayakana kemonotachi (1972)

One of the girls has her dark hair in a tight ponytail, wearing a tennis outfit like she just came off the court — she’s slim with small tits and rides her partner hard on a bed in what looks like a cheap hotel room. The other girl’s got a headscarf on, almost like a bandana, and she’s more passive at first, lying back while getting eaten out with direct tongue action on her clit. The camera gets in real close during the cunnilingus, showing wet lips and fingers sliding in and out during 69. They switch positions halfway — the one in the headscarf starts riding face, grinding slow and grinding deep, her ass bouncing slightly with each dip. No penetration with toys, just hands and mouths, but the chemistry feels raw and unfiltered, like amateur porn with a voyeuristic vibe. The lighting stays dim throughout, mostly practicals and natural light from windows, giving it a low-budget but authentic look.
