Isolated in her room, a curious teen explores her body's new sensations. She tentatively touches herself, gasping as pleasure courses through her. Her brother, hearing her soft moans, enters without knocking, catching her in the act. Embarrassed, she covers up, but curiosity piqued, he watches as she continues, now bolder. She spreads her legs, rubbing her clit, her wetness glistening. He can't help but stroke his growing erection. Caught in their shared taboo, they decide to explore together, fingers and tongues intertwining, their bodies pressed close in a dance of discovery.
