Chang fa gu niang (1975)

A curvy brunette MILF in white lingerie sits on a couch, setting the tone for a slow build. Two younger brunettes—one slim, one curvy—join the action, and things get playful before turning intense. The guy watches for a bit, then steps in, taking turns with each of them. The MILF takes control, riding him while the younger girls kiss and tease each other. It’s all about variety here—missionary, doggy style, and some great close-ups of oral action. The moody lighting and creative camera angles make it visually interesting.
