His mother and sisters around the TV.

Brett walked into his house, accouncing his presence. He heard no reply, but instead heard what sounded like a woman moaning and crying. He walked into the living room where his family, still topless, sat around the TV. It was blasting a porn video that he thought he could have jerked off to at the end of a long hunt for just the right porno. August Ames had a tongue deep in a busty woman's pussy on an operating table while that woman sucked a giant cock. Brett didn't recognize either of the other woman, but he made a mental note to learn her name later.

His family watched the TV, all three of them transfixed by the screen. His mother and Audrey on the couch, Gina in an arm chair next to it. All of them seemed incredibly arroused, breathing heavily, lips parted. Every once in a while one of them would give the same look of longing at one of the other women. His mother especially seemed to enjoy the sight of Audrey's F cups and was massaging her massive tits. He was almost surprised they hadn't given in and really masturbated in front of each other.

He decided on an experiment. How far could he push them before they either masturbated or fucked each other. First, he commanded them not to see him. He sat down in a place where he could see them all clearly.

Gina, with her smaller tits, would likely be the ignored one, so he decided she would be the aggressive one. He had already given Penny a fetish for tits, but he commanded Gina to have an obsession. She would want to stare a tits and lick them and would only want to fuck herself if she could think about them. The bigger the better. Immediately her enraptured fixation on the TV shifted to her mother's giant H cups. She almost drooled as her mouth wattered. Still, she didnt take off her pants.

Next, Brett gave his older sister a feeling of superiority and entitlement. She knew she was better than anyone else, and didn't have anything to prove. That tore it. With no reason to hold back, she slipped down her pants, put her hand to her shaved pussy, and began to rub her clit. The other two didn't seem to care.
