As the smoke from their shared joint swirls around them, the siblings find themselves in a world where inhibitions are but a fleeting memory. The brother's hands, rough and eager, explore his sister's body, tracing the curves he's never dared to acknowledge before. She moans, her head tilting back, exposing the long, elegant line of her neck. He leans in, his lips finding the pulse point, his tongue flicking out to taste the saltiness of her skin. Her hands grip his hair, pulling him closer, as she grinds against him, her hips moving in a rhythm as old as time. The haze of their lust intensifies, their bodies moving in sync, chasing the high they both crave.
