You make Tanya cum first, and You turn the tables on her

You position yourselves across from each other, and slide your legs above and below each others so that you could both easily reach each others pussy without the other one being able to pull away or try and avoid it, you both look at each other and smile as Marcus begins to countdown. Tanya looks over two the two mixtures that had been swapped but thanks to her own early underhanded and risky actions now both contained a mixture of very potent sperm and fake cum, no matter what, either you, or both of you would end up pregnant from tonight's fun and games. Tanya licked her own black lipstick covered lips seductively as she looked back to you, and she imagined the freckled beauty in front of her, as your belly begins to round and swell with a new life, your boobs threatening to pop free of all of your tops and bra's as the swell so heavily with milk. Tanya also wondered about the other mixture, and the consequences of her deceptive move. If she gets pregnant too without risking anything other than tonight then it'll become clear whats happened. she was sure that you would forgive her as you both swell up together, and then you'd have kids together, and she'd have to try and find new and inventive ways to get you to risk your body all over again.

You lick your own lips as you wonder if you'll get lucky, and finally turn the tables on Tanya, dump a load of Marcus's potent baby makers into her unprotected pussy, maybe you'll strike lucky and it'll take, and you'll get to watch your daring kinky lover swell up and then maybe you'll follow suit, but on your own terms, without this crazy fertility **** that's **** you to ovulate, god know how that's going to affect your normal cycle.

"Ok ladies you may start the race now." Marcus announces, as you roll your thumb over the wheel, and start Tanya off with a low setting to warm here up nicley, as you feel the glorious vibrations that travel through your own sensitive lips on a low steady rumble.

"Mmmmmm I think I'm gonna enjoy tipping that cum into you Tanya, turning the tables and watching the wonderful body of yours swell with a new life." You say in a seductive manner as you let out a soft moan, as Tanya rolls the wheel on her wand, the increased power making your pussy dampen quite quickly.

"So sure of yourself princess, I've been playing these games a lot longer than you have." Tanya says as she begins to slowly rotate her wand around your lips, causing you to let out a louder moan, as the vibrations travel around and tease your clit, which has began to peek through it's hood, as you feel a familiar heat slowly building inside of you.

Not to be out done you flick the power wheel back and forth from the highest to the lower setting, as you gently run the wand up and down Tanya's pussy teasing her aching clit with a mixture of low power and high powered passes over her swollen love button. "Good thing I'm a quick learner." You reply as a big moan comes from Tanya telling you that your plan is working.

You both keep up your tactics, slowly changing the power of the vibrations higher and higher, as you both quickly begin to leak juices, as your pussy lips begin to swell and engorge, as they prepare themselves to be as receptive as possible to the vibrations, and the pleasure the bring. Marcus is staring onward at the sexy display in front of him, he can feel life stir back into his cock, as he watches you too compete for the prize of potentially knocking the other up, or unintentionally sealing their own fate. He takes out a large pair of handcuffs, which he will use to bind the losers legs to the bed frame holding their legs above them, giving the sperm the advantage of gravity to help assist the possibly potent mixture. He looks over to the two half full containers wondering who will get lucky, and what the winner would even consider lucky. He watches as both of your legs begin to shake with your bodies, knowing that soon the end was near, and that with a satisfying squelch he'd declare a winner.

By now both of you were locked eye to eye, trying to psyche each other out as you try and bring the other to orgasm first, by now you'd of both normally cum, but due to the stakes you were both holding back, and soon the powerful vibrations, showing no mercy or care for the stakes, would declare a winner. You continue to slide your wand up and down Tanya's swollen clit, lowering it past her slit to gather up a good helping of her own juices to help keep her clit nice and moist as you try and vibrate it to climax. Tanya's own plan was also working it's magic but her hand began to falter, the pattern slowing as her hand shakes, and you knew this was your chance.

You quickly pressed the advantage as you began to quickly run your wand over Tanya's clit as her legs began to shake and her whole body quivered, you own not too far behind, but just as you were certain that this was a trap for you to tired yourself out, you own body reaching its limits, Tanya lets out a loud cry of ecstasy as her pussy convulses and gushes forth a big spray of juices covering your own pussy and the vibrator still working it. You find this too much and cry out also as you shake and fall backwards on the bed and flood the sheets with your own sexy juices.

You finally come too a minute or two later, after your climax subsides, you lie their panting, the thick smell of pussy juice in the air, as Marcus looks down at you with a big smile on his face. He offers out a hand and helps you upright, as you look over to Tanya and she that she has been moved to the end of the bed, on her back with her legs tied above her cuffed to the bed frame. You see a funnel in her pussy, and a wand sitting next to her.

"To the victor the spoils, pour the cup of your choice into the loser, and then bring them to orgasm with that wand, so that their body takes in as much of the mixture as possible." Marcus says with a smile as he passes you the two flasks. "Now if you girls don't mind I'm going to take my leave, before you get me into any more of your crazy schemes." Marcus says with a smile as he quickly dresses himself and heads out of the bedroom. "Good luck." He cries as he closes the front door behind him.

"Hmmmmm now I have to make a tough decision." You say as you walk closer to Tanya carrying the two flasks of cum mixture, unaware of Tanya's deception, but then again you had something up your own sleeve.

"Go ahead pick one, but then I'm pouring one into you, and I reckon I'm luckier than you are." Tanya says with a giggle as she looks up at you and sticks her tongue out at you.

"True, but then again you did try and trick me, and when I'm so **** because of that **** I took too. That wasn't very nice Tanya and I think it's time for me to get a little pay back." You say with an evil grin on your own face.

"Oh and Just what does my sexy soon to be pregnant princess have plan....." Tanya begins before she stops as she realizes what you had planned, but in her current conditions had no means to stop you. You looked down at her and smiled sweetly as you positioned yourself next to the funnel in her pussy, and begin to pour both flasks into her. There is a look of shock on Tanya's face as she gets her pussy filled with the cum mixture.

"Mmmmmm bet you didn't see that one cumming." You tease putting emphasis on the pun as you drain the flasks, and then pick up the wand.

"You.... sneaky.....cheating......completely brilliant princess, Oh god you got me good, and I rigged this round too." Tanya says as she shakes her head and smiles as you put the wand over her still swollen clit, and begin to start her off on a low setting as you sit and watch as the level of white fluid in the funnel begins to drain into Tanya.

"I figured you might of, and who knows if this sticks, you'll get to have your fun impregnating me, but we do this properly, risking it naturally, no crazy injections or bizarre traps, well maybe some sexy bizarre traps, but fair ones, which don't stack the deck in favor of impregnating me." You reply with a smile as you look down lovingly at Tanya as she smiles back at you as she moans from the vibrations being delivered to her clit.

"Mmmmm sounds good to me, and if it doesn't catch, then I look forward to playing fairly with you." Tanya says as you flick the wheel up, and begin to gently run the wand around her clit, teasingly like before, but running circles around the clit, just as Tanya tried on you.

"I look forward to that too, now hold still and take your medicine." You giggle as you watch as Tanya begins to shake and quiver as this time, not holding back she quickly orgasms from the wand, draining the remains of the cum mix in the funnel deep into her womb. You gently lower Tanya down, and climb into bed with her, holding her closely as you both drift off to sleep, wondering if this game had left Tanya with the star prize she was hoping to give to you.
