The Portuguese siblings, their accents thick and heavy, explore the taboo of self-pleasure together. The boy, his voice cracking as he speaks, guides his sister through the act, their eyes locked, breaths ragged. The girl, her cheeks flushed, tentatively touches herself, her body responding to the new sensations. As they continue, their movements become more confident, their moans filling the room. They don't touch each other, but the air between them crackles with tension, their bodies yearning for a release they don't yet understand.
