Dan Oniroku onna biyoshi nawa shiku (1981)

The scene opens with a close-up of a slim Asian girl with brown curly hair, getting fucked in a dimly lit room. She’s soon joined by another girl with similar looks, and they start going at each other. A guy in his 40s with a bald head and muscular build joins in, leading to a threesome. The girls take turns sucking his cock and fucking each other, with lots of close-ups of their faces and bodies. The camera work is great, capturing all the action from multiple angles. One of the girls has a surprisingly petite frame, but makes up for it with her enthusiasm.
