Basic Obedience and a medical

You and Tanya spend most of the half an hour with Tanya huddling around the old style furnace and getting properly dry and warm, with a little bit of exploration of the stables area to work out how to start the furnace up and how to sort out your water. Soon just as you were starting to feel as close to relaxed as you could in your current situation, Carla returns, sporting a small nurses hat ontop of her head, as well as a large apron infront of her catsuit.

"Alright, I hope you made the most of your break, because they will be few and far between." Carla says with a sinister smile as you look at Tanya and quickly walk over to Carla, before she snaps at you for not responding quickly enough. "Right, now we have some simple lessons to start you two off with, as I don't imagine you'll be capable of much yet. You both will also be undergoing a medical examination to make sure you're both fit enough for purpose." Carla says in a cold tone as her eyes narrow on you both.

"Mistress, what happens if we're not healthy enough for mistress's training?" You ask after a little hesitation, wondering if you even wanted to hear the answer.

"Why my dear, what normally happens to live stock not healthy enough to do anything?" Carla responds with a wicked grin, as you shudder and what she could even mean by that, before settling on not ever finding out.

"Now follow me I've got my equipment in the next room over, and don't dawdle." Carla snaps as she quickly turns and strides off towards the next room of the stable. You quickly follow her in and see a large metal cart, complete with various looking instruments and implements, most of which you hope are merely for intimidation value.

"Stand here and here." Carla says quickly pointing to two spots either just behinds her as she faces the cart and browses over some of the implements before settling on two. "Alright first things first, time to take temperatures." Carla says as she turns to face you with two thermometers. You open your mouth, and Tanya does the same before Carla lets out a wicked laugh. "Silly Thing, I need a better reading that that, bend over." Carla says with a michevious tone as she takes both thermometers placing them ontop of the cart, and then pulling on some large blue latex gloves.

You look over to Tanya with a look of nervousness as you sigh and resign yourself to your fate, bending over and presenting your rear to Carla who starts to hum as she takes one of the thermometers and presses it against your asshole, as you can't help but clench up in response. "Hmmmm looks like I'll need some lube." Carla says idly as she uses one to begin rubbing your pussy, before placing down the thermometer and wheeling the cart closer and using her now free hands to start rubbing Tanya's pussy too. "You two are very lucky that Mistress is in a giving mood, what do you say?." Carla say as you can't help but enjoy the feeling of her fingers as the tease you pussy.

"Thank you for your kindness Mistress." You and Tanya say in almost unison.

"Good, what you'll find out is that if you both behave and do exactly what I ask you to, that I can be quite a fair and generous Mistress." Carla says as you risk a sideways glance at Tanya with an expression on your face of sheer disbelief.

Carla continue to masturbate you both for a few more minutes, as you gets your worked up quite well, much better than you'd of imagined given the crazy situation. You figured you might even climax at this rate as that familiar warm pressure begins to build into a roaring fire, but then as soon as she started Carla suddenly stops much to both yours and Tanya's disapointment. "That should be sufficient." Carla says with a cold tone as she reaches back and fetches the two thermometers, and slides the cold hardended glass rods into your pussy, getting them coated in the same juices now running down your naked legs.

You wondered if maybe you might be able to climax from the sensation of being penetrated by the thing rods, but before you could think anymore on it, the thermometer is removed from your pussy, and then being presses against your asshole, this time slipping in slowly as you try your best not to clench up on the anal invasion.

Once the thermometer is lodger halfway inside your ass, and likewise for Tanya Carla leaves them in. "Alright I'll leave those there for now, just try not to suck those thermometers in too deep otherwise they could get stuck inside of you." Carla says in a cold tone as you try your best not control your muscles. "Oh and don't drop them otherwise you'll be punished." Carla continues as you try your best keep the thermometer in your ass in place.

Carla walks around to the front of you and takes your head in her hand and examines you, like a mechanic looking over a car. Next to pinches your nipples roughly and runs her hands over your hips. "Hmmmmm yes, I think you'll do." Carla says aloud before doing the same to Tanya. "Looks like I might have some half decent livestock, lets just hope you can follow my training." Carla says as she walks behind Tanya and pulls the thermometer from has ass. "Looks about right." Carla mutters to herself before walking towards your head. "Open." She says in a cold tone as you look up at her and spy the thermometer that was up until recently inside Tanya's ass.

You hesitate for a moment unsure if you can bring yourself to have Carla shove the thermometer into your mouth, before you try your best not to think about it, and slowly **** your mouth open wide. Carla smiles as she slips the thermometer into your mouth, as you try and ignore the taste in your mouth. Carla then slips the thermometer from your ass and puts it into Tanya's mouth as Carla laughs to herself.

Carla leaves you in your position for a minute or two ocasionally running a hand over your bodies or probing your with one of the various pointy metal implements before finally taking the thermometers out of your mouths.

"Well I'm not qualified by any stretch of the imagination, but you look like you're both healthy enough, but just to be safe take these now, and I'll provide you with more each day." Carla says as puts a red pill into your mouth and stands and waits for you to swallow, and you don't take a chance and make the effort to swallow the pill dry.

The rest of the day has you and Tanya sweeping the stables and generally cleaning the barn inch to inch. The work is hard and you feel yourself getting tired out quickly, but with Carla on hand to crack and actual whip she found you pushed yourself as hard as you could until finally you reached the end of a long first day.

"Well I guess you did a passable job for now, you should of found where your food is kept, so go feed yourselves and rest up as it's another early start tomorrow." Carla says with a smile. "Oh and don' try and give each other any relief, you'll need all your energy for tomorrow and I don't want you wasting it on pleasuring each other." Carla continues as she looks at you both, before finally turning and leaving you.

You and Tanya just about sort out another batch of fairly unappetizing porridge in the trough and eat as much as you can stomach, before cleaning it out and calling it a night, the both of your far too tired to do much else.
