A boyish, lively, and mischievous girl named Rio-chan. Once her remote vibrator makes her pussy hot, whether it's the emergency stairs or a family restaurant, she's "desiring..." at the age of 20. After enduring her moans for so long, she's taken to a love hotel where she experiences a spectacular gushing climax, screaming in ecstasy during a seeded 4P! The room was left in a complete mess afterwards.
