Princess of Darkness (1988)

Eliza Grant is on her knees, wearing nothing but black thigh-highs, sucking one dude while Hunny straddles his face beside her. You see a lot of mouth action — Eliza takes the dick deep, gagging slightly, then pulls off with a string of spit connecting her lips to the shaft. Hunny’s fully into it too, grinding her wet pussy against the guy’s mouth while playing with her own nipples. The lighting’s dim but the camera stays close during the oral, then pulls back for a wide shot when Eliza and Hunny start making out and going down on each other. One scene shows Hunny’s long nails digging into Eliza’s ass as she eats her out from behind, both of them moaning loud. The guy just lies there soaked in saliva, hard again, waiting his turn.
