Bedtime Eyes (1987)

The whole vibe is dark and moody, with dim lighting that makes everything feel intimate. Two Asian girls, both slim with long black hair, take turns with a guy. He wears a mask the whole time, which is kind of weird but adds to the vibe. One of the girls spends a lot of time on her back, letting him fuck her missionary while the other watches or joins in. The camera gets close during the oral parts, and you can see the eye contact. There’s some standing action too, with one girl leaning against the kitchen counter while he fucks her from behind. The masks and moody lighting make it feel different from typical threesomes.
