In the second act, Arthur's gay desires intertwine with his brother's straight curiosity. Arthur, his "pau" throbbing with lust, guides his brother's hand to his cock, teaching him the art of "punheta." The straight brother, hesitant at first, soon finds himself stroking Arthur's Brazilian cock with enthusiasm. As Arthur's moans fill the room, his brother can't help but feel a stirring in his own "pau," leading to a tense, erotic exploration of their contrasting desires.
