Sucking Siblings: A Forbidden Bond

A mysterious voice echoes in their minds, 'Suck, sister. Worship your brother's cock.' They comply, their bodies moving in sync. The younger brother, usually shy, finds his hips bucking forward, his cock sliding in and out of his sister's mouth. She takes him deep, her throat convulsing around him. He grunts, his fingers tangling in her hair, pulling her closer, fucking her mouth with abandon. She moans around his cock, her pussy throbbing with need, her own pleasure mounting as she's used for her brother's gratification.
