"Doryx, wake up!" Doryy's urgent whisper stirs her brother. She's on her knees beside his bed, nightgown bunched up, fingers buried in her pussy and ass. Doryx watches, hardens, and moves to join her. He pushes her onto the bed, spreading her legs. He tongues her clit, slides a finger into her ass, making her squirm. He stands, pushing his cock into her ass. She cries out, gripping the sheets. He pounds her, their bodies slapping together. They switch to cowgirl, Doryy bouncing on his cock. He cum's inside her, she collapses, and they lie there, panting and sweaty, their secret safe in the night.
