Shallow Grave (1987)

Alright, so this starts with four chicks—blonde, brunette, redhead, all slim, all in their 20s—standing by a red car on some country road, touching each other like they’re about to fuck. No dicks yet, just a lot of grabbing and whispering. Then the scene cuts to this jacked dude with short brown hair going at it doggy style with one of them in a bamboo forest. The angle’s low, right behind him, so you see everything—his ass flexing, her back arching. Later, there’s this petite Asian girl in a kitchen, looking all surprised, but she doesn’t do much yet. The best part? The doggy in the bamboo—super tight shots, and you can tell she’s really into it, moaning like crazy. No fluff, just straight-up fucking.
