Fatal Games (1984)

One of the girls has short dark hair and a petite frame, the other’s got long wet hair clinging to her back as they kiss in the shower. They’re both slim, pale, and totally into each other — she’s eating her out with her face buried deep, tongue working hard under the spray. Later, the guy shows up — early 30s, dark hair, decent build — and they bring him into the mix at a dimly lit bar before ending up in a gym. The final scene’s chaotic: six people on a gym mat, one girl straddling the guy while another leans in for a blowjob. Camera stays wide for most of it, no close-ups of faces but plenty of action shots. You see one brunette riding him hard from the side while the other jerks him off and kisses her. Not much plot, just straight group sex with real bodies and messy energy.
