The girls study the different types of anatomy and sexual relations. Girls get horny and fuck each other's pussies with vibrators, getting their own vaginal juices tested. Then they finger-fuck their pussies intensely until they experience intense orgasms. Two other girls enjoy it intensely. One of them is made of slime, and immobilizes the other girl, fucking her orifices making her moan with pleasure
