In the cramped practice room, Yui, Mio, Ritsu, and Mikako start their rehearsal, but the sexual tension between them is palpable. As they play their instruments, their bodies sway and grind, their breathy moans barely disguised as musical notes. Azusa joins them, her innocent eyes hiding a fiery curiosity. The girls strip down to their underwear, their bodies glistening with sweat as they pleasure themselves, their fingers dancing over their wet pussies in time with the music. The room fills with the scent of sex and the sound of their fingers sliding in and out of their tight holes. As they reach their climax, they collapse onto the floor, their bodies spent and satisfied.
