Fertility Roulette

"Whats this roulette one?" You ask hesitantly as all you have are a list of names. "Wow supreme choice, I can see why your taken with her Tanya she's almost as crazy as you" Harriet giggles. "Wait no, I just wanted to know what it...." You say, before being silenced by Tanya's lips, you're worried about what you accidentally agreed to, but also very happy to have Tanya's lips on yours. You worries immediately evaporate, melt away into Tanya's soothing kiss, as you taste the cherry flavor from her lipstick. "Mmmm good choice princess, were both at risk in this one. Basically we strapped into two chairs with very powerful vibrators strapped under our pussies. A needle with be places into our veins and hooked up to a computer. I'm not 100% on the science as honestly I don't care, but basically the more we cum, the more hormones will be pumped into us through the injection. It's Harriet's special batch so it works fast. A little will make us horny as hell, and enjoy sex more, too much though and it induces ovulation, way too much and we might end up with more than one egg to risk in part two." Tanya coos into your ear, and then giggles as she rubs your naked stomach. "We get to pick another game for part two, but needless to say it'll involve a lot of super potent sperm, either from a machine or maybe even some real cocks. If we do well in round 1 then the risk in part 2 is just a standard risk of pregnancy and we can use the morning after pill, however we fuck up, and not even the pill can save us." Tanya continues, as she start to finger your pussy. Her fingers feel amazing on your slit, as she works them inside you and gets you nice and wet. She pops her fingers out of you and licks them clean. She kisses you again, and you can taste yourself on her lips, which helps get you horny again. Tanya takes you to a set of chair, they look a lot like dentist chairs, but with extra straps. Tanya straps you into your kissing you on the lips, and then leaving to let Harriet strap her in,

You lie back in the chair and start to worry as it begins to move, it tilts you up slightly so you can clearly see Tanya in the chair across from you, she looks across at you and smiles widely. Next Harriet sets up the needs and hooks them into a jar of red roiling liquid, it has smoke coming off it. You really start to panic now, as Harriet pops the needle into vein, and walks over and does the same for Tanya. Finally she hooks up the lines from the needs into the vat of red liquid. She turns the valve and the red liquid flows down into lines and into your arm, you feel a tiny amount flow into you before Harriet turns another valve and starts up the computer. You feel a warm sensation in your pussy as it begins to engorge with blood and start to produce a lot of pussy juice. You look over at Tanya who looks like shes in the same amount of pleasure. You feel the chair slowly part your legs and something move up to your pussy lips. You look over to Tanya to see whats happening to you. The chair parts Tanya's legs and a black vibrator is moved up to her pussy, It nestles in deep as the chair stretches you and Tanya wide. The vibrator is one of those wand types which you've seen a lot of positive reviews about how powerful they are. Your nerves start to work overdrive, as the vibrator hums to life, thankfully on a slow setting, although even this weak it looks like you and Tanya are going to cum a lot. "OK gals, were all good to go here, the vibrator is hooked up to a random program so it'll swap patter every minute. You have ten minutes, to try and hold out as long as possible, you have 15 minutes. Finally I've hooked you up to some nice vitals, that can tell if you've ovulated or not. It'll announce it loudly so it'll be picked up on the video" Harriet announces as she walks over and gives you both a big kiss on your clits, oh shit you forgot this was being filmed.
