It has been a few weeks since you remade the world, and after the initial shock, you found life on the human ranch was actually pretty fun, relatively speaking of course. Sure there were some boring parts, but overall it wasn't too bad. You still haven't yet found where the Chronivac was being kept, but at the moment, you didn't need it. Mark, and his cock were more than enough to keep you good and happy for a while. Any repulsion you had felt before towards being a human mare, had almost completely vanished. Only rarely did you ever think about it, and often that was only when you simply had nothing to do.
After being impregnated by Mark, the both of you were moved into a double wide pregnancy stall. Easily the largest kind of stall in the barn. At 5 times the size of your single stall you started with, you and mark had plenty of room to mess around in. Since you were pregnant, sex was out of the picture as your pussy was sealed up tight. However the outside, and your breasts were still pleasurable enough to cause you to orgasm. Mark had gotten great at licking your pussy while you learned that with the right angle, you could fit his entire cock down your throat.
Sucking his cock had become a daily event for you. At first it was intimidating. But after a few attempts, you had gotten use to the feeling and now were even looking forward to it every day. On occasion you would even playfully give his balls a suck too. Especially right after he was taken out for a run.
Sarah had also began exercising you , albeit not nearly as intense as all the other mares, due to your pregnancy. You didn't know how being riden would work, given how Sarah was a horse and all, but she did it, and surprisingly, you managed to carry her weight with ease. Running was fun. However as the days went by, it grew less and less enjoyable. This was entirely due to the rapid swelling of your boobs. As a soon to be mother, your breasts had begun to produce breast milk, which made them becone a bit heavier and gradually larger and larger. Now they were large enough to where running would painfully smack them against your fore legs. Luckily yesterday was the end of your running as the beginnings of your pregnancy buldge had started.
Mother of 1 girl and 3 boys. That would be your future in just under 3 months, and then every 3 months from now on. Unless you were given a break that is. Your age group also had 2 other breeders join you. Clover, a ironically named red haired girl with 4 breasts. Due to her red hair, her body actually looked like it had a pink tinge to it. The other girl Kelly. She was a brunette who interestingly had a couple patches of snow white hair here and there, with a rather large one where her tail was, making her tail white in contrast with her brown hair. Like everyone else in the barn who became breeders, she too had 4 breasts. Kelly had Dave for a mate like you had Mark. Clover had a harem though, and it was not quite known who had impregnated her. But with some of the ranches top stallions always fucking her, no one was too worried that the offspring would be anything but great.
You were apparently the only one who knew what a blowjob was of the 3 of you. And had gladly instructed Clover and Kelly on how to perform one. Clover was pregnant like you were, so she was glad to learn. Kelly was half listening at the time because one of her harem had mounted her half way through and stolen away her focus. She later figured the rest of it out though by watching you and Kelly.
Currently, you once again had Marks shaft down your throat, when Sarah walked in. Needless to say, she was quite surprised to see you like that. She had figured that only horses knew how to do that and awkwardly walked over to your stall. "Come on Lady, you can er, finish doing that some other time. I need to get your progress checked. Wait! You too Kelly? Seriously, where did you both learn how to do this? You are seriously wasting all of their semen! We sell that you know!" Sarah tried to pull you off of Mark's cock, but you were not about to leave your man unsatisfied. "Uuughhhhh, fine. Just... finish him off quickly, ok. You have 5 minutes."
Like you even needed that long. By now you could blow Mark for over an hour, keeping him on the edge, or make him cum in 30 seconds if you wished for just a quicky. But hey, 5 minutes. You would be sure to use every second of the 300 she had given you.
Sarah walked back in the moment Mark came down your throat, causing semen to spill out your mouth as it overflowed. You also peed a mix of piss and cum, as your own orgasm had filled your pussy, and caused the pressure to surpass your limit. It was kind of fun forcing yourself to pee with an orgasm. It certainly felt much better than how it normally did. Maybe you would get to a point where you had to cum to pee, or you would cum simply by peeing? Either way the thought was exciting.
You slipped Mark's cock out of your mouth and licked up all of the globs leftover on your face and body. You were even tempted to get the ones on the floor too, but you were not that depraved yet, maybe someday though. You walk over to Sarah and go to lick her face, obviously causing her to move away. You had expected that, so you didnt mind. The two of you have a very close bond, and normally she would let you lick her face any tine you wanted, taking it as a loving kiss from a pet to their owner, but she was not about to let your cum soaked mouth lick her. You laughed at her reaction, as you had no intention of actually touching her, not that she would have ever understood that though. She carefully harnessed you, and lead your drooling self out towards the on-site veterinary clinic.
When you both entered, you were amazed to find that the Chronivac was sitting there in one of the empty holding stalls. The one you specifically were being lead into even. "So this is where you have been hiding" you thought. It seemed that no one else could see it too. You placed a hoof on the large pad, and the screen flickered on with the message "Welcome back, Lady!" appearing for a few seconds before fading, revealing your profile.
You had a curious thought, and made 2 quick changes before activating it. The first, was you making mares able to be fucked all throughout their pregnancy, as you missed having Mark's cock inside of you. The second was that you made exclusivly Sarah able to speak to and understand humans as long as you were nearby and/or allowed her to. You wanted to talk with her, as you considered her a close friend, even though she technically was your owner. Mark had even commented on how unusually close the two of you were. Most mares simply obeyed their owners, but you sometimes would joke and tease Sarah playfully, which often had either left her quite happy or unexpectedly disgusted like earlier, which she would then laugh at.
You could speak with her now, but decided to wait until you were back at your stall to reveal the big surprise.
