The First Nudie Musical (1976) (Better Quality)

This scene kicks off with a white brunette in her 20s, slim and short, sitting in a chair wearing a bow tie and suspenders, looking pretty surprised. Then we cut to a group of four mixed teens, all white, chatting in a hallway. Things get interesting when we see two of them, a brown-haired girl and a blonde with a pink hat, standing in a studio, checking out something. The blonde’s got glasses and a pretty slim build. Later, a non-Caucasian bald dude with tattoos and a mustache appears, but the main action is between the two white girls, who end up nude and holding objects in a bright studio. They get into some solid girl-on-girl action, with great shots of the oral parts.
