Back to the chairs for another game of Orgasm endurance

Tanya carries you back to the same chairs you were just strapped down to, you'd think it is funny how just moments ago you were doing the same for her in the opposite direction, were your mind not being completely clouded by lust, as the **** Tanya tricked you into swallowing takes affect. Tanya lies you down and kisses you on the lips, before the chair straps you in, before she seats herself and giggles as it locks her in place. The chair forces your legs apart and a cock shaped device slides into your soaking pussy, you let out a lusty moan and grip at the chair in pleasure, Tanya also seems to be enjoying the feeling as you hear her let out a moan of pleasure. "OK listen up girls and viewers." You just about hear Harriet say, as the cock shaped device drives itself deeper into both your's and Tanya's folds. "Now part two will see our sexy pair, be brought to orgasm after orgasm, in a sort of endurance run. Now we'll be making them cum as many times as possible in half an hour, at the minute the rules are that the girl who's climaxed the most in this time gets there pussy filled with the vat of super sperm you see above them in that tank, now they are both fertile from round one, and between the **** they had pumped into them, and the potency of the sperm in the tank, they'll be pregnant for sure. The sperm itself has been treated so that they'll all work together to try and ensure impregnation, despite them being from a wide mixture of people. Now The reason I say the current rule is the girl with the most climaxes gets inseminated, is because we added a hell of a twist. You see for each 5 orgasm each girl has we'll role on this special wheel here, which has all sorts of wild cards on them. They could end up reversing the rule, and the girl with the fewest climaxes get inseminated, or maybe hit a wild card where they both get inseminated, they're even an incredibly slim chance that they hit the jackpot, now that one is interesting, as the winner gets to pick what they win, they could pick to have all the effects of round 1 reversed and leave here safe and not knocked up, or they might to win the luxury of a further **** that could let them play a new game, or even the pleasure of personally knocking up the other girl." Harriet finishes explaining, in her every perky and cheery accent, not that you are in a fit state to be annoyed by her chipper personality.

You lie back, just about making out the wheel and the tank of sperm above you, you see tubes slowly lower from the tank into two smaller tanks with your name and Tanya's name projected onto them, then tubes from these tanks begin to lower down to you, and attach to the bottom of the cock shaped devices. Which you feel shift and even expand locking itself deep inside you, making you feel fuller than you have ever felt. You suspect this is so that if and when it floods you with the cum it'll keep it nice and deep so it has nowhere to go but inside your womb. "OK so 30 minutes is on the clock, lets start the game!" Harriet yells out, and the cock shaped device filling you soaking pussy begins to vibrate wildly, sending waves of pleasure coursing through your body, you can't even think straight from the pleasure, and you and Tanya both have your first climax within 10 seconds of the half hour. You think that with the **** in both of your systems that it seems like Tanya might not be able to hold out as well as normal and maybe you might win, you just have to hope the wild cards don't screw you over.
