As the sun dips below the horizon, casting an ethereal glow through the stained-glass windows, the siblings gather in the hushed confines of the confession booth. The creaking of the wooden panels and the soft sighs of their breath fill the void as they prepare for the rite of passage. Their fingers tremble as they unbutton their modest garments, revealing the untouched terrain of their youth. With reverent eyes, they examine each other, their breaths hitching as they trace the soft curves and lines of their bodies, searching for the proof of their virtue.
