Amidst the discordant notes of a rehearsal gone awry, Aoba and Ai find harmony in their shared lust. Ai's fingers, meant for the piano, now trace Aoba's chest, her touch igniting a fire that consumes them both. Aoba, his guitar now a mere prop, lifts Ai onto it, her skirt riding up to reveal her wet, eager slit. He grinds against her, the hard length of him rubbing against her clit, their moans syncopating with the erratic rhythm of their lovemaking, a symphony of their unbridled desire.
