Yumi and Mai, both fresh-faced and innocent, find themselves in a whirlwind of new experiences at their prestigious university. One evening, as they study together, they stumble upon a curious, discreet package from their roommate. Inside, they find two egg-shaped devices, smooth and sleek, with a mysterious, powerful hum. With a mischievous glint in their eyes, they decide to test the toys, their hearts pounding with anticipation. They slip the eggs inside their panties, their eyes widening as the intense, vibrating pleasure takes them by surprise. They gasp and moan, their bodies squirming as they experience their first, quick, and oh-so-satisfying orgasms with their newfound friends.
