In the realm of "Angel Legion Music No.5," a captivating melody unfolds, echoing through the halls of a grand cathedral. Two angelic sisters, forbidden to indulge in worldly pleasures, find themselves drawn to the alluring tunes of their brother's violin. As the music swells, so does their desire, leading to a clandestine encounter where they exchange heated glances and stolen touches. The younger sister, her eyes closed, imagines her brother's fingers dancing on her body instead of the strings, while the elder, her breath hitching, fantasizes about the taste of his lips. Their taboo yearning builds, mirroring the crescendo of the symphony, threatening to shatter their angelic façade.
