The house is quiet, but not empty. Two figures, entwined in the darkness, their voices low, their breaths ragged. The girl's fingers dance along her brother's length, her touch feather-light yet firm. He responds, his hands kneading her flesh, his thumb brushing against her clit, eliciting a soft gasp. Their voices, a mere murmur, fill the room with a symphony of desire, their words laced with the weight of their shared secret, their bodies moving in a dance as old as time.
