Sierra was devastated when she found out her boyfriend had been cheating on her throughout their entire relationship. Stepbro heard her whimpering from the other side of the room, and decided to cheer her up. What better way than with a raging hard cock and a built up load of semen to the face? Sierra couldn't be happier. The next day, stepbro thought him and sis were extra close now. He just went on over and started groping her. Sierra didn't know how to feel about it and wanted him to stop. The only way he would go away was with a BJ. Sierra gets down and dirty and begins to suck, but halfway through she stopped herself. It just didn't feel right. Or so she thought... Later that night just the presence of having her stepbro around made Sierra so hot that she couldn't wait to mount him. When it came down to the final cumshot, both brother and sister finally realized what they truly enjoy, and that's each other!
