Up in Flames (1978)

A curvy brunette with tattoos and large breasts starts things off by going down on a slim blonde with average-sized tits. The action moves to the couch, where a bearded guy joins in, holding the blonde’s tits while she lies naked. He gets a blowjob from the brunette before the scene switches to an office, where the same guy is now on the receiving end of oral from another older white dude with gray hair and wrinkles. The scene cuts back to the living room, where the blonde is sprawled out on the couch, the guy sitting nearby, watching her. There’s also a solo shot of the bearded guy lying shirtless on a bed, looking down at something off-camera. The variety of angles and settings keeps things interesting, and the performers are clearly into the action, especially during the oral parts.
