"Siblings' Forbidden Indulgence" -

The siblings' secret trysts become a weekly ritual, each session more intense than the last. They start with soft, lingering touches, but soon graduate to rough, passionate gropes. He becomes a master at making her squirm, his fingers finding her most sensitive spots with ease. She, in turn, learns to take him deep, her throat relaxing to accommodate his size. One evening, their bodies glistening with sweat, they finally succumb to the urge to cross the last boundary. He enters her, and they both cry out, the pleasure-pain of their taboo union overwhelming.
