The sister, a "puta safada," reveals her body inch by inch, her brother's eyes widening with each new expanse of skin. She's a vision of sin, her body ripe and ready, her eyes filled with a hunger that can't be satisfied. She strokes his hardness, feeling it pulse in her hand, knowing that they're playing a dangerous game, but unable to stop. Their lust is a wildfire, consuming them both.
