A brother and sister, bound by blood and circumstance, find themselves in a dance of desire. He's older, stronger, his body a map of muscles and raw power. She's younger, softer, her curves ripe and ready. They've lived together, grown up together, but never like this. Never with this hunger gnawing at them, this need clawing at their insides. As they stand there, inches apart, the room filled with the sound of their ragged breaths, they both know they're teetering on the edge of something dangerous, something forbidden, something they can't resist.
