Steven Universe - Happy Birthday, Steven

Pearl, Amethyst, and Garnet did not actually know what sex was so they went by what they heard. The first 15 minutes is them tossing Amethysts head around, the 20 minutes of the tossing corn into a hole they dug into the ground, the it end with them getting mud facial treatments at the beach city Salon and Spa. They found it very relaxing.
