The siblings, their faces flushed with desire, explore each other's bodies, their fingers tracing sensitive skin, their mouths tasting, their teeth nipping. The sister's moans fill the room as her brother's fingers expertly stroke her clit, her pussy clenching around them. She returns the favor, her hand wrapping around his cock, her thumb swirling around the head, spreading pre-cum. They switch places, the brother now on top, his cock sliding into her with ease. He pounds into her, their bodies slapping together, their cries of pleasure echoing. They climax together, their bodies tensing, their eyes locked, their taboo lovemaking complete.
