Nono and Momoka, two friends with a shared love for music, find themselves in an unexpected situation. As they sing together, the atmosphere becomes charged with sexual tension. Their voices harmonize, but their bodies have other ideas. Unintentionally, their hands wander, touching each other's curves, feeling the heat that's been building. It's Nono's first time, and Momoka, experienced but gentle, guides her through their passionate encounter. The room fills with their soft moans and the rhythm of their bodies moving in sync.
