The girl that made this video says she's the sister of the horny couple. Her story is that the three were alone at their granny's house where they usually like to spend the Summer. Her sister hours before this, found out that the guy she was dating was cheating on her with a friend, and being a proud dumb bitch (her own words) couldn't accept the idea of being dumped just before she decided she wanted to dump the guy first. She needed some revenge sex quickly so she could swallow it better and the closest victim was their submissive brother, who she likes to use and abuse every time she needs.
