Atame! (1989)
The blonde girl, probably in her early twenties, has long hair and a slim build. She’s fucking a brunette girl with short hair, also slim, in a bathroom in front of a mirror, then they move to a kitchen counter. The blonde girl is on her knees giving oral while the brunette stands, then they switch positions. The camera captures a lot of close-ups, especially during the oral scenes. A male, possibly in his fifties with grey hair and a mustache, appears sitting in a living room but doesn’t interact with the girls. The bathroom has a toy tub, adding a playful touch.
