Magic Fingers (1975)

The scene opens with two slim white girls going at it on a bed in a dimly lit bedroom — one blonde, one brunette, both with long hair and no clothes. The blonde is on her knees, mouth wide open, taking the brunette’s tongue deep during a nasty makeout. She switches gears fast, moving down to eat her out with her face buried in her pussy, lots of wet sounds, fingers spreading, close-up shots showing every swipe. Then the guy shows up — white, early 20s, lean but muscular — and they bring him into the fold. He starts kissing the brunette while the blonde gives him a solid blowjob, head bobbing fast, cheeks sucking in, one hand jerking the base. They end up in a three-way tangle: the brunette riding the guy while the blonde leans in to lick her tits, then both girls go down on him at the same time, swapping off, one deepthroating while the other works his balls. Camera stays tight on the action, mostly close-ups, but there’s a wide shot near the end that shows the full layout — messy hair, tangled limbs, colored bedspread rumpled under them.
