In the bustling halls of Houkago Tea Time, Yui, Ritsu, Mio, and Tsumugi find solace in their shared love for music. But when the lights dim and the rehearsal room empties, they discover a different kind of rhythm. With instruments cast aside, these anime schoolgirls pick up a new beat, their bodies moving in sync as they explore each other's curves. Nylon-clad legs entwine, uniform skirts hike up, revealing glimpses of innocent flesh. They're not just playing music anymore; they're playing with desire.
