Fatal Fix (1980)

One of the girls has short brown hair and a tight, petite frame — she’s the first to start going down on the long-haired brunette sitting across from her. The van’s dim interior gives it that casual, backpacker feel, with blankets and pillows scattered around. The blonde just watches at first, jerking off while rubbing her own clit, then switches places to eat the first girl out. The camera stays wide for most of it, no cuts to extreme close-ups, so you see the full bodies moving together. There’s a lot of natural moaning, no fake sounds, and the lighting from a small overhead lamp keeps everything visible but soft. They switch positions halfway — one girl gets flipped onto her back and spread open wide while the other dives back in, tongue working in deep circles.
