Pure Taboo - Scarlet Skies [1080p]

Troy (Max Fills) and his stepsister Rachel (Scarlet Skies) are being scolded by their stepmom Cathleen (Serene Siren), because they're always fighting and have now been suspended from school because of it. Cathleen grounds them as punishment.
Cathleen warns them that if they try to leave the house, she'll know about it since the front entrance security camera has a direct feed to her cell phone. Cathleen also demands that they use this time to learn to get along with each other. With that, Cathleen leaves for work...
Troy and Rachel realize that if they work together, they can get back at Cathleen by using her own rules against her. They'll 'get along' alright - but in a way that Cathleen HATES. Troy and Rachel start brainstorming ideas to 'get along' with each other that they hope will make Cathleen angry, but they quickly discard the ideas as not being good enough. They then realize that they can use the security camera to their advantage.
They try to come up with something to do in front of the camera that will infuriate Cathleen, and decide that the most twisted way to 'get along' is by having sex with each other. Eventually, Cathleen checks the camera feed from work, and is shocked and livid to see the stepsiblings fucking.
