The boy, entranced by his own rigid desire, strokes his 'verga' with urgency. Meanwhile, his sister, driven by her 'lechita' lust, can't help but envy his pleasure. As their breathing synchronizes, the line between virtue and vice blurs, and they're left to grapple with the consequences of their forbidden encounter.
