She does, but you don't have any idea what for now.

Carla had been in an exceptionally good mood since you and Tanya were fucked at the demonstration for various guests, investors and possible clients, and had been treating you both incredibly well, with her lessons barely involving anything humiliating or degrading. In fact much to your surprise, she's been allowing you and Tanya to sleep in the farm house, and in the same bed as Tanya.

You slowly drift off after a very nice meal with Carla, including a very rich and delicious desert, you feel Tanya's warms arm wrapped around as her heavy naked boobs press into your back. It was almost normal for the first time in a long time, and if you had the energy for it you'd be enjoying Tanya's body more, but the heavy meal was making you both drowsy, and there was always the morning for it as you both drift off to a deep and peaceful sleep.

A few minutes later the door to your room slowly creaks open, the sound punctuation the rhythmic breathing of both you and Tanya, as the place light leaks leaks into the room illuminating the foot of the bed, as a soft footed person slowly creeps in through the gap, the creaking of the wooden floor boards not disturbing either of you or Tanya.

"They're dead to the world Mistress." Claire says with a light giggle as the chain around her collar rattles lightly with her movement.

"Very nice work my pet." Carla says in a sultry tone as steps in behind Claire, as Claire turns to face her and giggles as Carla strokes her face. "Now be a dear and set up the equipment to get these two ready for Madam Alison's visit tomorrow." Carla says as she kisses Claire on the cheek, before squeezing her ass cheeks through her Latex skirt.

"Right away mistress." Claire says before slinking away and out the door her chain rattling with each step as she leaves, leaving you and Tanya alone with Carla as she watches you both sleep, before turning and bringing in a metal tray and placing on set of draws by the bed.

"Mmmmm my sleeping beauties, so peaceful, if only either of you knew what tomorrow holds." Carla says in a devious tone as she giggles lightly to herself as she slowly peels backs the covers of the bed, and reveals your entwined naked bodies. Carla smile as she takes out a digital thermometer and moves over between your legs. She pauses for a moment as pokes you to see if you react, but all you do is murmur still deep in your slumber, as Carla does the same to Tanya.

"Yup those sleeping **** really work fast, guess I don't have to worry about disturbing either of you." Carla says to herself as she moves your legs apart and using one hand to part your moist pussy lips, she inserts the digital thermometer into your velvet channel, until she reaches your core, as she awaits the results. She gives it a good number of seconds before slipping the thermometer free and noting the temperature, and also the slick coating from your pussy on it. "Mmmmmm unless I'm mistaken, you're ovulating, now lets see about the other one and see if my calculations were correct for both of you." Carla says with a giggle as she wipes down the thermometer and then takes a reading from Tanya.

A large grin covers Carla's face as she realizes that you are both are at the peak of your fertility cycle, just in time for tomorrow. Carla wonders for a moment just how many studs Alison would bring with her, and begins to feel herself getting incredibly horny.

"Mmmmm no chance either of you are finishing tomorrow without a bun in those ovens, but seems such a waste to not use these." Carla says to herself as she picks up one of a pair of syringes filled with a pale red liquid.

Carla walks over to you with syringe in hand and rolls you onto your side resting one hand on your soft round ass, as she brings the syringe up to the skin. She hesitates for a moment wondering if she should do this. On the one hand you were both getting knocked up tomorrow, but then again you curious to see if the injection would work or not. She wrestled with the morality of her action for a few seconds.

"Come on Carla just inject them, sure it's an untested formuala which will give a healthy boost to fertility, whats the worst that could happen to them." Carla says aloud to herself. "I mean yes they're both already pumped up with fertility ****, and it's already almost a sure thing, do they need this too?" She continues as she wrestles with her internal monologue, before a metaphorical devil voices a single opinion. "They fucked with Emma." Carla says solemnly as she stabs the syringe into your ass, and depressed the plunger, as the liquid drains into you, and gets to work putting your fertile body into overdrive, before taking the second syringe and doing the same to Tanya.

Carla looks at you both with a wicked grin as she pulls the covers back over you and Tanya. "Sweet dream my mare's because tomorrow some stallions will set you on the path to motherhood." Carla says with a giggle as she takes the tray away and slips out of the room, to go see how Claire was doing with the other preperations, while you and Tanya continued to sleep peacefully, completely unaware of what was in store for you tomorrow.
