In a homemade video, a brother and sister, both virgins, find themselves alone together. Boredom turns to tension as they eye each other's bodies, their innocence slowly slipping away. The brother, unable to resist, orders his sister to touch herself. She hesitates, then tentatively runs her fingers over her pussy, gasping at the sensation. Encouraged, she spreads her legs wider, allowing her brother a better view. He strokes his cock, watching her intently, until they both reach their climax, leaving them breathless and questioning their newfound desires.
