In "Girls learn how to fuck" Mila and Sunny wanna stimulate each other so they're learning English together. They get together every day to study and practice but it can sometimes get a bit boring so they need to shake it off and get back to work. So our sweethearts try something interactive - getting rid of their clothes so they can learn what each part is called but when they get to the pussy, they have the urge to deepen their understanding and see how well they can eat it and finger it until each orgasms.
