Her younger brother lost his job, his wife left him and he's full of debts. The only place to run away from all the problems is to hide in his sister's flat. He sleeps naked all day, eats, drinks and goes to the toillet. One morning she noticed her brother had huge hard-on while he was sleeping and decided to put her hand under the blanket just to feel it in her hand. That made her really wet. After that moment the tought of sucking his cock didn't left her mind anymore. She started doing it every morning to see if he would wake up, for a week he pretend he was sleeping, then she found out but it was too late, she was already addicted to it and continued doing it every morning.
