He gets a bit jealous

John watched the line of men walking up behind his aunt and brutally fucking her, there was so much semen inside her right now that whenever a dick was removed from her ass the pressure caused it to start leaking out down her legs. The next dick would plug up the flow but even so she was still standing in a rather large puddle of it and her legs were coated in it. It was sort of disgusting and a pretty big turn off. John suddenly had an idea to keep all that familial pussy to himself.

Women are regarded by the government as natural sluts therefore all women are, during puberty fitted with an anti-slut chastity belt and collar. The belt is a high tech device that only allows those genetically related to the woman to fuck her pussy or ass. A genetic relative can also expand the number of people allowed to fuck the woman, the relative must be male and a woman is never allowed to expand permissions on her own although if a woman has no male relatives they can petition the government to allow them to be enslaved to a close male friend who then may determine their future sexual partners. The collar prevents the penises of men not on the approved list from entering a woman's mouth of fucking their tits, it also by command of someone on the approved list can cut off their motor functions, induce dyslexia, cut off speech functions, and raise the woman's sexual pleasure by up to 10x. If a woman is found not wearing a collar and belt they are regarded as rogue and are free to be enslaved.

John smiled as he finished the truth and then watched his aunt suddenly on her waist appeared a slick high tech looking belt that covered her ass and pussy the belt was sleek and white and fit perfectly to her body John suddenly remembered that one could barely even feel the belt while fucking a woman. Her pussy and ass were still proudly displayed but John knew there was an invisible **** field in front of her pussy and asshole that would make it so that only the approved cocks could get in and, since his uncle had died three years ago and his grandfather had died ten years ago, John was the only approved cock around.

Her collar in contrast was medieval in its design the cruel look of it got John hard and he grabbed his hovering mother's wrist, **** her to her knees, and without even looking at her rammed his cock into her mouth. The collar was heavy and metal it was clearly uncomfortable to wear and as John surveyed the crowd he recalled this was by design. He reminisced back to his high school days when the collars and belts had been explained to the students.

The teacher explaining had been a woman and her adult son, her only living male relative, had been there to help with the demonstration.

"So in 1978 the "Slut Law" was passed by a unanimous vote from congress. The law declared that women are all by nature sluts who need to be controlled by men in order to keep the public order." She had said making a minor adjustment to her collar that clearly did nothing to help it sit better. "This was in tandem with Gerald Helman inventing the anti-slut chastity belt and collar which were regarded as the key to enforcing the Slut laws. All women are now fitted with one when they reach puberty." She had waved her hand towards the class and the many girls most of whom were also fidgeting with their collars. "The belt is designed so that sex is possible without it's removal as removal of an anti-slut device is a crime. As my son will now demonstrate." Her son then removed his pants and without further ado rammed him dick into her from behind. She continued the lecture as best she could from there. "As, oh god that's good, you can, ahhhh, see if you look, oh yeah, at my son's dick. OH GOD THAT'S GOOD! The **** field i-i-i-i-is, allowing his dick through." She then descended into moans and began moving to give him a better angle. She was indeed right though that around the edges of his dick one could see the faint whitish glow of the **** field. Finally both of them came to orgasm he exited her and after catching her breath she started up her lecture again semen dripping from her still exposed pussy.

"Now the **** field is designed so that urine and other fluids can pass through it but the only solids that can pass through are approved dicks and paper products for cleaning. This was done since Congress reasoned that if women could play with themselves they would do so all the time so something needed to be done to keep us sluts in check." She demonstrated this by attempting to touch her own pussy and the **** field stopped her fingers with it's soft white glow. "The collar has numerous functions but we'll be talking about the most basic ones. As most of you are aware anti-slut collars are designed to fit uncomfortably. The collars are made of a special metal that changes shape to match its user so even extraordinarily fat women are still wearing their original collars. The collars are designed to never fit comfortably and stay tight so that women never forget that they are inferior sluts. The functions of the collar obviously include making sure unapproved dicks cannot enter the mouth or touch the tits of a woman and the "Slut control features" designed to make sure sluts don't get too uppity. The first of these is.." Suddenly she went silent no sound came out of her mouth despite her clear attempts to talk. Her son had pushed a button on a remote he was holding and after about a minute pushed it again. "As you can see my son has demonstrated the first feature a measure to make sure sluts are only heard when men want to hear them." The class stared at Bridgette Jones who no one could remember speaking since she had her collar attached her dad simply did not think she should be allowed to. "For the next function I will need some help I sent a message to your parents this morning so the function should be active for every girl in the class. Mary will you please open your textbook and read section 4 on page 345?" Mary got out her book confused she opened the book to the required page and then opened her mouth to read.

"Um no I can't ma'am the letters don't make sense."

"Can any of the women in the class read this?" They all took out their books and tried to similar results. "The next function of these collars is to remind us how fundamentally stupid women are and can induce dyslexia at any time preventing us from reading the simplest of sentences. The final functions are designed to control the most unruly of sluts. The collar can completely strip motor control as well as increase sexual pleasure to the point where no slut can resist getting some dick." Her son then hit a button and she collapsed immediately like a puppet with its strings cut. He then moved a dial on the remote and fucked her again, while he was fucking her she pissed herself unable to control it everyone in class could see her cum at least three times. Finally as he was about to finish he let her regain her motor control so she could scream for her final, powerful orgasm. She stood up weak kneed and panting explaining how there were multiple types of collars and that some allow much more control and are placed on criminals or rogue women.

John was brought back to the present as he came again into his mother's mouth. He looked up at his aunt and fingered the remote in his pocket. He could make this speech pretty humiliating if he wanted to or he could go back to some more old memories.
