As a potential investor, you take a tour of a facility and learn about Billy Bob's transformation into cowgirl Billie Boob as a cure for lactose intolerance.

Rule 1: you belong to mistress, you are her cowgirl… go ahead say it, “I am Mistress Dyvia’s Cowgirl”


Rule 2: if you have any kind of prosthetic breasts, keep them close, but don't put them on… until I tell you to.  If you don't have any, that's okay. We can pretend.


Rule 3: pour yourself a glass of milk, if you don't have any, any beverage will do, if you're lactose intolerant, don't pour yourself a glass of milk. Whenever you are commanded to take a sip of your drink, you will say aloud, “I can't believe how good that is.”


Rule 4: If you see any instructions between asterisk, you will follow them to the best of your ability. 


Rule 5: you will not come until you are told to. When you are told to, you will… if you are in long-term Chastity for a reason outside of the story, don't… instead, when you are commanded to come, you will write, ‘ I am so fucking desperate to cum, please someone save me.’ 10 times… you may not copy and paste. 


Enjoy.



Mistress Dyvia presents:

Intolerance

By: Mistress Dyvia



Well hello there. I'm sorry you're not going to be allowed to take your cell phone into the facility, but don't worry, when you leave the guards will return it to you.  I'm glad you could make it, I know you've been looking for a good opportunity to invest in something that has long-term financial gains. Let me start by offering you this…


Pick up your glass of milk


I know it looks just like a regular glass of milk. But it is not. It has been produced by one of our products, no no… it's not a chemical creation. Take a sip. 


Take a small sip of the milk.


See? It is really good, it's very high quality, it tastes very similar to the kind of milk you get from a grocery store, only there's a little something more to it… something almost sweeter but not exactly. It's hard not to take another sip, isn't it? 


Take another small sip of milk.


Anyway, I need you to take a walk with me. I want to show you something. 


If you can't really walk around, tap your feet slowly pretending like you're walking. If you're by yourself at home, reading this on a cell phone or tablet, I want you to walk in small circles as if we're walking side by side to somewhere


While we are walking, let me tell you about a man named William Robert Smith. His friends called him Billy Bob, he hated that because it made him sound like a redneck, and he was a professional architect.  About 5 years ago, he ended up coming down with a medical condition he couldn't quite understand.  It seemed multiple times a week he would have violent stomach episodes, cramps, nausea, diarrhea… sometimes it would leave him bedridden for hours with massive dehydration and or headaches. It seemed just as he was recovering from it, he would come down with the same symptoms again… severe symptoms. 


As one can imagine he went to the doctor, they took some blood and ran tests… as you probably already figured out, they discovered he was lactose intolerant.  Now this was a man who liked his lactose-based products. He drank a whole glass of milk with every meal like he had since he was a child…


Take another sip of milk


Yes, it is good, and sorry I just put that idea in your head… anyway, where was I? 


Oh, yes… on top of that, almost every meal had something cheesy, if he was eating broccoli there was cheese on it. Pizza was his favorite food, cheeseburgers were his favorite lunch. Pasta had parmesan and he certainly preferred an alfredo sauce rather than a tomato sauce. He loved his ice cream for dessert. You get the idea, this wasn't just life-changing, this was soul crushing for a man like this. 


But, there were pills you could take… Take a pill before the meal, eat it, and he would be fine. Except it wasn't a permanent solution, it seemed that the more he took these pills, the less effective they were. Within a year, The pills were completely ineffective, and he had to cut all lactose out of his diet, or he would be sick and miserable for hours. 


Rub your nipples with three soft circular motions with your free hand… that's three times each


Are you okay? Your nipples are bothering you? Don't worry about that… let's keep walking…


So there were companies working on some treatments for lactose intolerance, they were looking for trials. Billy Bob volunteered for them with the help of his doctor, but he was ultimately rejected.


As you know, we have been working on research involving milk ourselves. We've put a lot of money into helping women provide breast milk. We've been providing alternatives to milk such as almond milk, coconut milk, soy milk etc… and of course we've created some amazing breakthroughs with lactose intolerance medications… of course those medications need human trials. 


Billy Bob was on a list of rejects for certain companies. We used some data brokers to get a list of people like him, and we reached out. He was very interested. He came down to one of our satellite offices and we discussed what we wanted to do, and if he came he would have to stay at the facility, you would have to sign an NDA, and it would be monitored closely daily. 


He agreed.  


The day he showed up, he was handed a little purple pill, and he swallowed it… an hour later he was sitting in front of a tall glass of milk, and he would drink it in just a couple of gulps…


Take another sip of your milk.


Yes it is very good, and again, I'm sorry if I triggered you by telling you about that part in the story… sometimes it's hard not to drink that milk. 


So…. Getting back to the story, 6 hours passed, and Billy Bob did not show any signs of any kind of problems whatsoever. It was like he had been years earlier: he could eat and drink all the lactose products he wanted with no regrets. 


For lunch that day he had that cheeseburger he had missed for so long, And it wasn't just any cheeseburger, It was a double cheeseburger, with two squares of cheese melted into the burger, with sprinkles of bacon bits, parmesan, asiago, with a little layer of lettuce and tomato… and he was in heaven. For dinner that night he had a personal Pizza with extra cheese and the crust was filled with mozzarella. He even got to eat two entire and massive bowls of ice cream… 


I know… I know… are you fucking kidding me? Am I trying to turn him into a fat lactose-filled guy that's going to be stuck on his couch for the rest of eternity?  No, no, nothing like that… he just got to have a nice day where he could make up for years of not being able to eat all that stuff… in truth, I think we were just as surprised as he was that he was able to eat all that. And he went to bed that night with a smile plastered on his face…


Unfortunately, he awoke with a scream. Somehow overnight, his body had changed while he was sleeping, his waist had shrunk down, a lot of his features became softer, feminine… and then the most obvious change of all were the two ginormous breasts on his chest. 


Of course we were all freaking out cuz he was the first person to take this medication. Nothing like this had ever taken place in any of the animal trials… none of this should have happened in any of the simulations… and yet here he was, less than 24 hours after taking these pills, sitting there looking like a woman, with giant breasts. Of course, we also learned pretty quickly that his genitals… her genitals… had doubled in size as well. 


As you can imagine, everyone is freaking out. Billy Bob was freaking out, she didn't want to be a woman. Legal was freaking out because they were afraid they were going to have one massive lawsuit on their hands. The scientists were freaking out because they weren't expecting this and didn't know how to fix it. 


But this was a science issue and some things popped up over the next several hours. The first thing was that once each breast reached a size double that of her head, they started dripping milk…


Have another sip of milk.


Yes it is very good milk, I completely agree with you, but moving on… They quickly found out something very interesting, her breasts would go down to a simple B cup once she had been milked of approximately 10 gallons, yes they wouldn't stop producing milk until she had been milked of 10 gallons, and then she would produce no more milk unless she drank something with lactose. 


So of course we thought we had the perfect solution, don't let her eat anything with lactose and see if she went back to normal… problem happened: apparently the pill we gave her, not only cured her lactose intolerance, but actually gave her a chemical reliance on lactose… She had a seizure. So unfortunately, we had to make sure she was having at least a little bit of lactose, though luckily it didn't seem to matter how much she took, as long as she had at least a little within 6 hours of being milked… just a few enzymes could trigger the entire process over again…


As the days passed, we kept testing and we found some very interesting results… The larger her breasts got, the more passive she became. 


In fact, we found that if we properly stimulated her little nipples, the more we played with her breasts, the more her mind became open to suggestion.  


Rub your nipples like you did before, this time keep doing it until you've read the next two paragraphs


And we found that she would do just about anything. As I said, she was passive when her breasts got to a certain size, but that would be simple things  like ‘come with us’’ and she would follow. But there was still some sense of self in there… ‘want to have sex with somebody?’ If she didn't want to, or she wasn't attracted to, she would recoil… she would ask not to, she would find it hard to raise her voice… but if we started rubbing those titties, and remind her that she really did like that other person, then she would agree… She would even seem eager…


You don't mind me referring to her breasts as titties anymore do you? I mean breasts are what regular women have. She had titties and they were always nice and large and filled with milk.  


Say out loud, “I prefer titties."


I'm glad we can agree on that. Titties is such a more appropriate thing to say for a cowgirl like that. Yes, we decided to call her a cowgirl cuz of the size of her titties. And the way we were milking them of course. 


In the lab we had created a stall for her. Nice soft ground that way when she was on her hands and knees, she wouldn't have any discomfort. And then they would insert a gag in her mouth with a phallic milking agent to provide plenty of lactose into her mouth. And then they would start pumping her breasts… they actually started collecting some of her semen as well, it turns out when you spend hours being milked it made her extremely horny and she just made a mess everywhere.


Here we are, my office… let me hold the door open for you, why don't you have a seat. 


Stop tapping your feet or walking, and sit down.


Let me show you a picture of Billy Boob.. oh I forgot to tell you about that, we stopped calling her Billy Bob, she's now Billie Boob.


As I was saying, we were milking her from both her tits and her big cowgirl cock… that's a BCC not to be confused with the BBC… though some of our cowgirls since got to have both, just not all…


Billy Boob was an excellent initial study. We did a lot of tests on the fluids we took from her.  And she enjoyed it. She was on her hands and knees nearly 12 hours a day, she slept 8 hours a day… and she was her normal self for about 2 hours a day… With two hours that seemed to fluctuate from day to day… 


But the real breakthrough is what we learned from her chemicals. The milk she produced was surprisingly lactose free, we're able to bottle it up, and with a little bit of testing, we have been very confident that we can get this onto the shelves of every grocery store in the country.  Her semen awkwardly had some interesting anti-wrinkle compounds in it, were able to break it down, and produce some face creams that were great for hydration, and like I said, removing wrinkles…


But the strange thing we found, if you mixed her chemicals together, a ratio of about 10 particles of milk to one semen, it created something new… whoever drank that milk, would start developing the same symptoms that Billy Boob did.  Just a simple big and tall glass of milk which tasted so refreshing… Seemed so innocent… 


Finish your glass of milk


… Would result in a person whose chest started becoming very sensitive…


Start rubbing your titties, don't stop until your next instruction


And then we would have another cowgirl. Another girl to milk, another girl for the facility to be milked… another source of revenue for us. Sure, we could give people with lactose intolerance the pill, but we could give anyone the one to 10 ratio of milk from one of our cowgirls, to make more cowgirls.


And see that your nipples are sensitive today… can't quite seem to stop can you? … Sorry my cell phone's buzzing, I'll have to take this, we can finish conversation in a fewnminute…


If you have those breast forms, now is the time to put them on. Whether you do or not  put your hands between your knees like you were trying to stop yourself from playing with them.


Sorry about that, important call… oh I see, look at that, your titties are already growing.  They already look big enough to make you compliant. 


Let me see your hands, here feel this as I take your hand and pull them up to your own titties…


Imagine my hands guiding yours, roll your eyes into the back of your head as you squeeze them once. Let out a soft moan. Keep caressing them


You might remember the part where I said that Billy Boob was very suggestible when her big titties were being stimulated… let me just show you how so…. Repeat after me…


Repeat the next 10 sentences after mistress


You want to be a cowgirl. 


You love your titties. 


You want to be milked. 


You love the idea of being on your hands and knees with your big titties hanging from your chest. 


Makes you so horny to be Mistress’ play thing.


You are a dumb little fuck toy. 


You want to produce 20 gallons of milk a day 


You want to make more cowgirls. 


You will never argue with Mistress, she is always right. 


Being a submissive cowgirl is a dream come true. 


See?  That wasn't so hard, just doing what you're told and mistress will stimulate your big, fat titties. And even as you say it, I bet you noticed that everything you have said, wasn't even wrong. It was very true, and very right.


Now, as I was saying when we first met, I have an investment opportunity for you… we're looking for people with lots of money, and if you have at least a million dollars, I can make sure you get milked once a day, we can even come to your home and do it for you… And we can provide a pill that you can take daily, so you can get back to your normal life… for 18 hours at a time… get milked just like you are right now… and back to normal.


However, if you don't have that money, I'm afraid you're going to have to stay here at the facility… So what do you want to do? 


Now if you feel that you are a super rich investor, and you haven't done so already… you should join my Flames tier… if you feel that you are not a super rich investor, it's time to get on your hands and knees on your bed, take your blankets and scoop them up so they're touching your titties and your crotch, and then start moving back and forth like you or the cowgirl looking for a little extra stimulation or do both, and tell me that you want both


Well, I guess we have your answer. What a good little cowgirl you are. But I'll let you in on a little secret, regardless of which you picked, you were doing exactly as I needed you and your titties to do. But since you have been such a good cowgirl…  It's time for the reward.**You will cum now.**


The End. 


I hope you enjoyed that, It actually ended up being a lot different than I originally planned for this story.  I hope you are entertained, and I hoped you were able to follow as many rules as you could and enjoy it. Also would just like to say, you don’t have to join ther flames tier, but you know: Shameless self promotion.  Had to put it in there.  :)  Be sure to leave a comment and/or Email, you can review the story, you can give some thoughts, or just announce to the world how much you wish you were a cowgirl like this!  


Till next time.I love you all, and thank you for taking the time to read. Xoxoxo!
