Kikuchi Eri: kyonyû-zeme (1988)

Kikuchi Eri is blindfolded and pinned down on a bed, her large breasts bouncing as some guy pounds her from above. She’s slim with short black hair, totally exposed and taking it deep in close-up shots that don’t cut away. Another guy steps in for a blowjob — she’s sucking him while still tied up, her mouth full and eyes covered. After that, they switch to missionary with a different dude, both of them grinding slow and hard, sweat showing on their faces. The lighting stays dim throughout, all focused on the bed, no awkward cuts or skits. Camera stays tight the whole time, zero filler — just raw, direct sex with minimal setup.
