The Red Queen Kills Seven Times (1972)

So there’s this artsy setup with big windows and easels everywhere, right? Two chicks—a slim blonde and a brunette with wavy hair—start messing around, touching each other, getting undressed slow. The guy with slicked-back dark hair and tats on his arm joins in, and they’re all over each other on some draped fabric. The blonde’s got freckles, which is a nice touch, and the brunette’s got this look like she’s really into it. They don’t rush—lots of kissing, hands everywhere, before he finally bends one of them over a table. Doggy style with the natural light hitting just right, so you see everything. The camera’s not shaky, and the angles are solid, especially when the blonde’s riding him later. No crazy positions, but it’s got this chill, classy vibe that makes it stand out.
