Step-Daddy gets Daughter and Her Slutty Friend

After her mother died, my step-daughter and I were the only ones left to take care of her mother's estate. We did it all: we sold the house, we got rid of the car, we even took care of the money. I know she was sad and I wanted to make her feel better. So I told her I would take her shopping for anything she wanted. She asked for some clothes and shoes, but then she asked if she could buy some lingerie. I told her she was a grown woman and she could buy whatever she wanted. When we got to the store, she asked if I would help her pick out something sexy. We found a few things that she liked and when we went to the register, the cashier said that it was on sale for 20% off. She looked at me and smiled. I think she knew what I was thinking.
