In the dimly lit room, the teen girl sits on her bed, her laptop open in front of her. She's watching a video of another girl masturbating, her eyes wide with curiosity and a budding desire. She tentatively touches herself, mirroring the girl on the screen. Her body responds, her nipples hardening, her pussy throbbing. She's clumsy at first, but soon finds a rhythm that makes her gasp. She's so lost in her newfound pleasure that she doesn't hear her mother enter the room. Her mother watches, her expression unreadable, before she steps forward, her voice low, "Let me help you, darling."
