A taboo fantasy unfolds as a sister, alone in her room, lets her imagination run wild. She envisions her brother, naked and vulnerable, his cock hard and ready for her. She pictures herself taking it in her mouth, feeling the veins pulse against her tongue, tasting the salty pre-cum that beads at the tip. Her hands explore her body, mimicking the touch she wishes was his, as she brings herself to the brink of orgasm, his name a whispered prayer on her lips.
