Kayla's eyes widen as she accidentally walks in on her brother in the shower, his cock growing hard under her curious gaze. She quickly averts her eyes, but the image of his hardening length is already etched in her mind. She teasingly asks if he's 'grown' yet, to which he confidently replies, "I'm big enough to show you." Their playful banter takes a turn as Kayla's curiosity gets the better of her, leading to a tense and sexually charged standoff between the siblings.
