As they work on an anatomy assignment, two motivated students, Nataly and Diana, determine that a more "hands-on" approach could help them learn more effectively. There's no better way to gain an understanding of the human urinary system than to really feel it and see the activity up close. Nataly starts things off by putting her nude pussy in Diana's face. Nataly uses precise pressure from her fingertips to launch a jet of pee into her friend's gaping lips. Diana does the same with Nataly, but instead she hovers over her face, her pussy lips agape. She doesn't aim quite as accurately, though, and her shooting geyser of golden pee ends up drenching her classmate's entire upper body. The naughty lovers exchange some hot piss as Nataly launches another expertly timed river. The girls start swapping and spitting the acidic nectar until they realize they actually like the way it tastes. They soon finish the last drop of the nectar. After learning about an intriguing and erotic world that they had only ever heard about, Nataly and Diana are now obsessed with kinky pee.
