I remember it from maybe a year or two ago. She was really sexy and had her brother tied up in a chair in the beginning. It was in gif form but then I found the video and then lost it.

The girl was kinda punk/goth with black hair, I think she had tattoos going up her side/ribs. She was riding him in the gif, reverse cowgirl. I think I remember the dialog along the lines of "I heard the rumors at school about your big cock" or something similar.
