Brianna, a naive teen, is caught off guard when her brother walks in on her nude, masturbating. Instead of anger, she sees his desire, his cock straining against his jeans. She bites her lip, feeling a new kind of power. She doesn't stop, her fingers moving faster, her breath coming in short gasps. He watches, entranced, his hand moving to his crotch. She sees this, feels a surge of excitement. She's never felt so alive, so desired. She wants more, wants him to touch her, to fuck her. But she's not ready to voice her desires, not yet. She keeps touching herself, her eyes locked with his, a silent promise of what's to come.
