Amazing Dr. Jekyll (1975)

Redheaded girl with a slim frame and zebra-print top takes on two guys in a tight indoor setup. One guy has a mustache and a muscular build, the other’s leaner with curly brown hair — both are white and in their 20s. She starts with a blowjob on the curly-haired guy while the other jerks off nearby, close enough you see every detail of her lips stretching. They switch off, both deep-throating her in turns before she gets on her back for double penetration — one in her pussy, one still fucking her face. Camera stays tight during oral, especially on the cumshot close-ups when both guys blast cum on her chest and mouth. Her ring is visible the whole time, left hand flexing as she guides one dick with her hand while sucking the other.
