Brand of Shame (1968)

The desert heat sets the tone for this outdoor fuck session. Two brunette girls, one in a white shirt and hat, the other in a black vest, take turns riding and sucking a muscular guy with short brown hair. The wide-open setting gives you a clear view of everything — the horses and cacti in the background make it feel wild and dirty. The girls are slim and look like they’re in their 20s, while the guy’s got that rugged vibe going on. Doggy style against the fence is a highlight, with both girls getting pounded hard. The guy finishes by jerking off all over them, leaving them marked and satisfied in the dirt.
