In the throes of boredom, a curious sister explores her sex toy collection, pulling out a realistic dildo that catches her eye. She locks her door, settling onto her bed, and begins to tease her clit with the toy's textured tip. As she grows wetter, she slides the dildo deeper into her hungry pussy, fucking herself with increasing fervor. Lost in her pleasure, she doesn't notice her brother entering the room until he's standing at her doorway, his eyes wide with surprise and arousal.
