I love the setting. A couple of ideas:
Due to the imbalance of males and females, all girls (15 and older) are required by law to give birth to at least two boys by the time they become 25. They are required to prove on a monthly basis, that they tried to get pregnant by having sex at least 15 times a month. So they need at least 15 CFs (confirmed fucks) in their "fuck book". This means every time they found a guy to have sex with them, they need the guy to confirm that by signing their fuck book. The guys can also rate the girls for their sexual qualities.
Should a girl fail to provide the 15 confirmed fucks for two months in a row she becomes an execution candidate. Meaning she can be legally killed by any guy at any time.
Imagine a world in which each girl between 15 and 25 is desperate to find guys who would fuck them, so just that they would reach their monthly quota....
Girls who fail to give birth to at least two boys are also publicly executed on their 25th birthday.
Those rules really helped keeping the female population over 25 in check. Also it helps the more attractive girls to stay alive, since the uglies never reach their fuck quota. As a result we're living in a world with mostly attractive girls under the age of the 25, which are constantly desperate to find the next cock in their pussy.
It didn't take long, until men figured out what desperate girls would be willing to do, for a "confirmed fuck". So instead of just having sex with them, they took advantage of the girls' desperation by forcing them into really fucked up torture sex. So imagine going into a snuff bar where a bunch of hot 15year-olds in slutty dresses hit on you, because they are already 5 fucks behind this month and desperately need a couple of confirmed fucks in their fuck book. While you watch the live execution show of a beautiful 14-year-old on the stage, who gets machine fucked by a hydraulic fucking machine that thrusts the spiked dildo deeper and deeper into her tight teen cunt, you let 4 of the 15-year-old take turns riding on your hard cock. While one the girls rides your penis, the other three have to masturbate the muzzle of a revolver, that has 2 bullets in the 6 bullet drum. If the girls want a chance of your cum inside their pussies they have to masturbate themselves to a genuine orgasm and pull the trigger... The first girl is lucky... as she cums and pulls the trigger with trembling fingers, it only clicks.... She swaps with the girl who just rode your cock.... the lucky girl will get her chance to make you cum inside her, while the other girl will have to play Russian Pussy Roulette, if she wants another chance. Only seconds later one of the other 2 teen girls moans to an intense orgasm and pulls the trigger. BAM! You can see her sexy belly rise from the hot gas that shoots through her womb. The bullet ripps through her body, exits through her back and hits an innocent 16-year-old waitress who was just giving a blow job to a another customer. 1 down, 3 to go. While you enjoy fucking the pretty girl on your lap, the fourth teen girl spontaneously climaxes as she sees her friend dying in front of her. Being in some state of shock she can't manage to pull the trigger within the time. According to the rules she will be executed later on stage to entertain the other guests of the snuff bar. Meanwhile the 14-year-old on stage finally died from the spiked dildo that fucked her as deep as her lungs. She is being replaced by two blond teen girls who enter the stage and will now compete in a masturbation contest with explosive dildos. While you watch the two beauties desperately thrusting the deadly dildos in their sweet little teen pussies you feel your orgasm coming closer.
"If you want my sperm better finish now", you tell the remaining girl, competing for your cum... Only seconds later she closes her eyes and climaxes extremely hard... her trembling finger reaches for the trigger... you can feel your orgasm building up.... BAM! There goes another pretty teen girl, having herself shot through her teen pussy. As if this wasn't enough to make you cum, one of the pretty blond girls on stages finally manages to reach a genuine orgasm... Now the other girl has only 5 seconds to climax as well, or her dildo will explode. The audience of the snuff bar chants the countdown 5...4...3...2....1... boom! The explosion isn't strong enough to kill her instantly... instead her vagina explodes in a fountain of blood.... The sight of the exploding girl seems to have triggered a gigantic orgasm with the teen girl riding your cock. You can feel her tight pussy spasming around your hard cock... You could easily just cum as well... shooting your load inside her climaxing vagina. But since you're a real sadist you just push her violently off your lap... she falls backwards and slams her head against the table.... what a rude way to interrupt and ruin her orgasm. Then you point your hard cock at her face and shoot your large load all over her cute face. She looks at you in disbelieve...
"Well thanks for making me cum, bitch... but since I didn't iseminate your pussy I can't possibly have made you pregnant. Sorry, no confirmed fuck for you!", you laugh into her cum soaked face.
Then she reacts in the most humiliating way, by grabbing the sperm with her hands and rubbing it inside her teen pussy. Watching her desperately stuffing the cum between her wet pussy lips and begging you for the confirmed fuck signature is the most degrading thing you have ever seen....
Another wonderful evening at the snuff bar is about to end... before you go home you force a 17 year old cute waitress to masturbate with a bottle of champaign and crush the bottle inside her vagina right as she cums... with millions of small glass pieces insider her pussy, you force her to take a larger piece and cut off her swollen clit for you. Even though she complies under tears of pain, you decide to kill her anyway. Than you grab your coat and head home, where a bunch of disposable teen whores are waiting for you...
What do you think? Is that a nice way to make use of this "perfect" world? What would you have done in the snuff bar? I'd love to read your ideas and give me some feed back!
