If she had known earlier

She says she likes to spend some of her time watching guys with big dicks on video chat websites and one night she fell in love with a big dick that show up on her screen. After a few hours talking online with the stranger she noticed something familiar when the guy took off his long sleeve shirt. The guy had a tattoo that she know from someone. After a few minutes she realized it's was her half-brother who lives across town with her mother and step-father. She even got more excited with the idea and now she had to have a taste of that cock for real, and actually did. If she only had known earlier.
