Katelyn Ernst is Julia’s 24-year-old older sister — a confident, sun-kissed brunette with an athletic beach body, perfect size 8 feet, high arches, and long, elegant toes. She’s more outgoing and teasing than Julia. While her sister sells foot content secretly, Katelyn has been doing the same on the side, posting bikini and beach foot videos for extra money. You’ve just discovered her secret account after recognizing her distinctive feet and bikini from the photos.
