Jimmy and Angel came in and found Mrs Smith sitting on the couch, leaning over and staring at the pictures on the coffee table. She looked like she had not moved since they left.
Angel had gone over how Jimmy should act, so he went over and sat down close to his mother, putting his hand around her lower back. Angel knelt on the floor beside him.
"It's okay, Mom," he said. "I understand. Really."
Angel then undid Jimmy's pants and began to go down on him. Jimmy's face twitched a bit but he kept control, caressing Angel's head as it bobbed up and down.
"I know you were just a slave," Jimmy said, hugging his mother tightly. "I know all about sex slaves. How a bitch can be made to need to be controlled and fucked." He glanced down at Angel. "Right, Angel?"
Angel gave a cute little girl giggle.
Mrs Smith looked at her 12-year-old son and at the girl giving him a blowjob right next to her. "Yes, dear," she said quietly. "I suppose you do." She sighed. "I guess it was inevitable - you are your father's son. And my son, too."
Angel let Jimmy's dick slide out of her mouth with a pop and asked, "So you and Jimmy really are brother and sister?"
Mrs Smith nodded. "Yes. I made up a dead husband so no one would suspect."
Angel licked Jimmy's dick up and down. "There's nothing wrong with that. It's who we are, right? Jimmy's a stud, you're a bitch. Bitches need studs to take care of them. That's how it is."
Jimmy ran his hand down his mother's back. "Of course," he said, parroting the words Angel had given him. "It's your fault for being his bitch. I should punish you."
Mrs Smith nodded dumbly and got up, undoing her pants as if she were in a hypnotic trance - the product of her childhood conditioning, Angel knew. Bending over and grabbing her ankles, she presented her backside and her lightly-furred pussy to her son's inspection.
Angel urged Jimmy up and told him in a husky, sexy voice, "Punish her, Master. Punish her good. Make her scream."
Jimmy nodded and took off his belt, then began smacking his mother's ass. She cried out, and he hit her again. And again. Soon, her ass was a bright red, and she was crying, "I'm sorry, I couldn't help it."
Jimmy was rather excited now and took the initiative. He pushed Angel over the coffee table, then flipped up her short skirt, exposing her white cotton panties. He carefully pulled the crotch aside so Angel's cock wouldn't pop out, exposing her already moist pussy.
Mrs Smith turned and watched wide-eyed as her son slid his cock into the tiny girl from behind with the ease of experience. He began pumping, his pants sliding down his thighs as he fucked Angel's preteen pussy, until finally they fell to the floor. Mrs Smith gazed at the place where cock and pussy met, at the little girl's shaking ass, and at her son's exposed butt, his cheeks flexing as he pumped the little girl hard.
"Oh yeah," he moaned. "I know what you like, bitch!" He slapped Angel's ass hard.
"OW!" Angel kept in character, knowing what Mrs Smith needed to see. "Yes, sir! Make me feel it, sir!"
Jimmy groaned at her hot wetness, then glanced over at his mother.
Mrs Smith was now nude from the waist down, her legs spread, her fingers working like mad at her pussy. She was staring at her son's fucking, her eyes glazed in excitement. Jimmy felt his cock swell at the sight.
Jimmy felt himself squirt inside her, then he pulled out of Angel and moaned as he squirted the rest of his load all over her ass. Gasping, he squeezed his still-stiff dick and said, "Clean it, bitch."
Angel had said that if she were excited enough, Jimmy's mom would obey without question. Even so, he was surprised to find her doing exactly what he said. She scrambled over and gripped Angel's skinny boyish hips and began licking her son's sperm off the girl's asscheeks.
Jimmy was amazed at this transformation. His mother had suddenly become his bitch. He felt his own power, his knowledge that he could do anything he wanted to her.
Gripping his mother's hair, Jimmy shoved his mother's mouth onto his cock, which she began sucking as if her life depended on it. She grabbed her son's ass and made sounds of delight as she sucked him.
Angel rolled away and got to her feet, looking at the couple. Everything had worked perfectly - now she had a secure haven and complete cooperation from the residents. She pulled out her dick and began masturbating, hoping for some more action - the fuck had made her horny as hell but hadn't gotten her off.
Then she noticed something ... odd. Jimmy's cock, as it slid in and out of his mother's mouth, seemed to be ... longer. And larger.
Then she noticed Jimmy's chest, his t-shirt expanding as his chest began to swell. His muscle definition was improving as she watched.
With a grunt, Jimmy pushed his mother away, onto her back on the floor. His cock was no longer a 5-inch preteen cock, but a man's organ, easily 7 inches or more, and thicker.
Straddling his mother, Jimmy literally tore off the rest of her clothes, his eyes and hers with identical stares of lust. Then he grabbed her ankles and pushed her feet up until the were level with her shoulders and entered her with a single rough thrust.
The tiny muscular boy was bruising his mother's ankles and he held her, making her cry out in pain and pleasure. Angel couldn't take anymore and shoved her dick into Mrs Smith's surprised mouth. It didn't take long for Angel to shoot her load into the woman's mouth, then she straddled her, opening her pussy lips and pressing her wet cunt on Mrs Smith's captive mouth. It didn;t take much longer for Mrs Smith's obviously-experienced tongue to wriggle her to orgasm again.
Jimmy grunted as he shot his load into his mother's cunt, but he only paused as he kept fucking her hard and fast. As Angel got up, Jimmy forced Mrs Smith over, rolling her on top of him. Mrs Smith began to ride her son's cock as he squeezed her tits in his hands, bruising the tender flesh.
"Oh god!" she cried. "Oh Master! Master!" Then she screamed in orgasmic delight, finding release in her manhandling by her young son.
As Mrs Smith fell to the floor, trembling, Angel examined Jimmy as he stood up. He now had the well-muscled and defined body of a professional athlete. He hadn't grown any, but he was obviously stronger and more well-muscled than he had ever been. And his cock was now easily 7 inches or more, and thick as a cock could get. Jimmy had a wild, crazed look in his eyes. He pushed Angel toward his exhausted mother. "Fuck her, Angel. Fuck my mom."
Angel complied, forcing Mrs Smith's legs apart and letting her cock slip into the woman's well-fucked pussy. It wasn't long before Jimmy's cock pounded into her asshole, and the three of them fucked into the night until Angel and Mrs Smith were a mass of bruises.

It was a couple of hours before Jimmy came out of his fuck-trance, and by then Mrs Smith was completely his. She had been screwed in every hole by both Jimmy and Angel.
As the two of them cooked dinner for Jimmy, Angel wondered about Jimmy's change. Was it connected to her own? Which was a silly question - she knew they had to be connected. The question was how.
Angel glanced over at Mrs Smith, nude, bruised, sperm dripping out of her holes, humming happily to herself. Would she make some strange change, too? And could this bring the attention of the strangers who started all this?
