The company says it shot Brady just as she turned 18, edited the sets and uploaded the content, which went live within 15 hours.
"I'm amazed at all the attention I'm getting," Brady said. "Well, all the attention my boobs are getting. I couldn't wait till I was 18 so Laura could shoot me and get my amazing pics and videos out on the Internet."
Candygirlcash said it specializes in finding young girls with big breasts and great personalities.
"In this day and age cookie cutter sites aren't converting," said Laura Jenkins, owner of CandyGirlCash.com.
"You need a gorgeous girl with a really strong character to cut it. And that's what we have with Tegan. She's natural, British, beautiful and feisty. Surfers will love her."
