Young Girls Do (1984)

One of the brunettes has wild curly hair and a slim frame, pushing the blonde down to her knees in the office scene. They end up in a classroom with books and a chalkboard, both completely naked, eating each other out for real — long tongue work, fingers deep. The camera stays close during oral, no fake motions, you see the lips and fingers working. Later it shifts to a dim bedroom where one brunette gives a blowjob while the other watches, then joins in. Doggy style happens fast — one girl on all fours, getting pounded hard from behind. The lighting’s natural in the day scenes, artificial and moody at night, keeps it raw and direct.
