Her oldest brother Brian was smart and kept away from her. Grace was a year younger than Brian their mother and father had split some years back, his mom had become like Grace. Then there was the accident and after hanging on for three days she died. Now her husband and herself were simply split up and had been for some time. They had not bothered to get a divorce. Or a new will. They had made the will years back when they were still together. The will said that in case they were not together any more or either one was killed in an accident that all the money property and assets were to go to the oldest child. that meant Brian. The will was for a half million dollars and different properties and a business. His father came over immediately after hearing that his wife had gotten in an accident and died. He then arrived with a lawyer in tow expecting to walk out with the money. His lawyer looked over the will very carefully several times and turned to my father. Who did you have write this will? he asked my dad. Well he was supposed to be the best. Brian's dad started to get nervous, well he was indeed the best because it does say Brian being the oldest is the only heir to the money, property and all assets including the business. Not you nor Grace just him, Brian dad was upset and left saying never to expect to see him again. Grace on the other end was furious there was all that money and none of it was hers and she had to live off of his "contributions". She started to dream up different always to separate him from all that money. She came up with the perfect plan. She ordered On-Line without him knowing it some pills that were supposed to make a change in his life. These pills were supposed to change him into a certain type of "girl". He was still going to be a man having all the equipment but also being a girl when one looked at him because she was planning to blackmail him into giving her total control of his money and then she would assure him that she would change him back. She was of course Not going to change him back but to simply throw him out in the street penniless. No one would know about the change They would not know that he was not doing it intentionally. Grace got the pills and she went to Brian and told him that she was going to start to take vitamins so that she would look fit and trim and she wanted her big brother Brian to take the vitamins with her they are good for you after all. Brian knew she was immediately up to something for Grace never was polite or caring. She went out with her friends the following day and Brian got up and went to see what was going. Brian went in her room, she for some reason keep the Vitamin pills that she was giving him in her room. He was stunned, Grace was ever forgetting things. This time she Really had fucked up she had forgotten to take the label off the pills and the warnings. Brian knew what she was up to then, he smiled well two can play that game. He changed the vitamins that she was going to give to him for regular vitamins. He went to his computer and after looking at many websites he found what he was looking for vitamins that would change a girl into a man with a dick and all. The day Finally came he had ordered a half dozen bottles this is just the start he smiled. He carefully took the label off and put all the pills in her bottle. In the mean time he went out and got some more real vitamins and placed them in the bottles she had stashed away to give him. She had been giving him two tablets of five hundred milligrams in the morning and evening. She was taking the same amount from her bottle of what she thought were "real vitamins". She started after about six months to feel strange. Grace didn't know why Brian had went and bought a large southern mansion outside of a small village in Mississippi they had about 6 acres and were well of the beaten path and twenty miles from the village. Brian had asked her if she wanted to come live with him. She didn't have a job and she was family and he didn't want to toss her out in the streets. She of course agreed she was feeling very strange but she didn't know what it was. She had stopped arguing and scheming against him but instead she was coming to depend on him for everything. She still ordered the vitamins for Brian. They however did not seem to be working maybe they just needed some time. She however was not only being given the vitamins but he had gotten for her a different type of drug this was in a type of a sweet tea that was to make one more easy to do one's will. He had noticed a subtle change in her that her clothes didn't really fit anymore. She didn't notice the change in herself. She of course did not realize the tea she was drinking all day long and the drugs that she was taking made her not only change but she thought the change was natural. about six months later when she was taking a shower Brian walked in as she was coming out and drying herself off. For some reason she didn't seem to mind it Brian however saw she was growing a dick it was very small but it was a start. Soon he thought very soon he smiled. He started after about another six months going in her room when she was dressing she was growing more and more. She did however stay looking like a girl with a girl's pussy but also with a dick of her own. He walked in on her when she was drying herself off. Hey why don't you clean the house today and fix dinner? Okay Brian. That's great why don't you wear this. Grace looked at it and said sure with out any hesitation. Why don't you wear them with these? Brian handed her a pair of thongs that were very see thru and cut very high. Sure anything for my big brother. She started to go to her room, Ah why don't you just change right here looking at her? Why didn't I think that. After stripping Brian said before you get dressed let's take a good look at you turn around slowly. She obeyed with out one word. Very nice very nice indeed no let me help you to get dressed okay. Brian slid his hand over her dick don't that tickles. But it does feel good doesn't it and Brian kept stroking her dick as it grew harder she moaned a little bit. Why don't you rub it and he placed her hand on her dick and started rubbing it up and down she kept going and starting to go faster. She was moaning and groaning and she then shot off her cum. Oh god that felt good! Brian smiled well let's get you dressed now I have to wash up first. Why? Just lick it clean okay and she started licking her own cum. Now around the house you are Greg. you will do Everything I want you to do you understand? She hung her head ok Brian. You mean Sir don't you? Yes Sir. Now there is a little place I found in another city that has your kind of entertainment. We will be going tonight but first you will need some clothes. They left for a small specialty store. What store is this I don't recognize it? Really you will be going here often Greg. They walked in looking like a couple but Grace had on a regular skirt and blouse. That was going to change there were no other customers as it was about time to close the owner seeing only the two customers told her help to go home that she would handle them. The owner went over and locked the door. Brian smiled as the owner came to them. Well what would you be interested in today? Brian spoke up. Well Greg and myself are going to a party tonight and she I mean he needs the right clothes. Mary the owner looked at Brian well maybe we should look at what we need Greg started to the dressing room. No I have a place in the back that is more private. We followed her and she stopped in an area that had spot lights. Greg be a good little girl and show her what she has to work with. Greg/Grace slowly stripped Mary smiled. Brian watched Mary and her expressions. Grace had a hard on, well we can not measure anything with it being hard like that as Brian looked at Mary and gave her a wink. She moved to Grace. Hey what are you doing Grace asked. Take it easy you will like it Brian said mean while Mary had pulled her dress then panties off she made her lay down on a couch they had there. Mary had started to slowly suck her dick. As she did this she got more and more horny and finished getting him off she rolled him over got him hard again. Now Grace you will fuck Me! Grace was stunned she was on her back and this woman was on top of her! She dropped herself onto Grace's dick and started a slow steady fuck then picking up speed she was finally slamming herself onto her with no regard and then she tightened and let out a whimper and held herself buried on Grace's cock. Mary pulled herself off of Grace and was just lying there. Mary looked at Brian I think we have the right clothes for her. They went out and after a little time they came back their arms full of clothes. Here Mary said put this on first, she handed her what looked like a garter belt. It goes like this Mary strapped it on her and Greg saw it had a huge dick. Oh god! She then brought out a pink garter belt and sheer stockings. Put these on, she hesitated, Now Brian said sternly yes Sir sorry Sir. She put the garter belt and hose on lets see no I don't think so what about you Mary? No I think we will have to go to the others. Let's try this Brian said as he held up the black one. The perfect choice they pulled out an even shorter black leather micro mini skirt and a black garter belt and fish net hose. She started to try it on and found that it didn't even cover the top of her hose I did however show part of her ultra sheer panties and the outline of her bulge she then had to put on a see through blouse that was cut so very low so you could see everything and no bra. Now we have to see which will look best on you. She held up a mini skirt of sorts. This was the shortest she had ever seen. Try it on let's see what it looks like. Grace pulled it on it was so very tight she could barely get in it. Let's take a look in the mirror. Oh god! It barely covered her panties let alone her garter belt. Brian don't you think I could wear something that wasn't so short? You don't want to disappoint me do you? No I would never do that, she said quickly. Good let's put on your make up so you look real nice for me. Grace had long jet black hair so her outfit was a perfect match. Well Mary and I decided that as you were already dressed as my slut that she will put your makeup to match that of a slut okay baby? Of course anything for you! I have one more thing for her it will be perfect. She brought out a dog collar she went in front of Grace, Now when you wear this you will be your brothers slut you will do everything he wants. Mary looked at Grace is that clear? Yes I will do anything that he would request. Okay let's put this on then, She went and put on the dog collar on her it had spikes on it. Okay Grace when you are wearing this you will be Greg right? Yes anything to please him. Very good now who are you? Greg that is what my Brian wants. Now pull your skirt up I said jack off and at the same time suck my dick. She didn't even hesitate but pulled up her skirt brought her dick out and started jacking off and sucking my dick at the same time that's it Greg take me deeper I put my hands on the back of her head and started forcing her up and down she had her hand going harder and faster jack hammering herself off. I finally shot my wad deep in her mouth and held it there she was gagging so much she tried to bring herself out I held her there until she swallowed every drop. She changed into her new outfit at the store and they left she was wearing the blouse that showed everything and a super short micro mini skirt that had to be custom made and wearing four inch high heels. She was dressed and looked every inch the total slut. She had hold of Mike's arm and they slowly went to his car letting all see her. When they got in the car Mike had already dressed for the night out and he leaned over and kissed her. Let's go to dinner babe. He took her to an expensive restaurant and the customers were staring at her. They had finished their meal when the manager came over. Miss I don't mean to tell you your business but will you please refrain from bringing your customers here in the future. He took a deep breath this is a public family restaurant and I'm afraid the customers are more than a little shocked at the way you are dressed. So please if I may escort you out, he pulled out her chair and looked at me. Sure I'll get the tip but you'll work that off. The manager was shocked as I said it loud enough for some of his customers to hear it and I dropped a twenty on the table. The manager led her quietly but firmly out. The manager stopped me and whispered try to convince her not to bring her clients her again. I'm sorry to do this to you, you have been in impeccable taste and your welcome back she however is most definitely not! Grace was at the car, why was he so mean to me I didn't do anything to him. Did I do something wrong? No Greg you didn't he was probably mad that he didn't get the chance to have you suck his cock. Should I go back in and show him I am sorry? No we have a party to go to remember? Oh yes I love parties! We got in and the club was a good hours drive. I started telling Grace about the vitamins that she had been making me take and she hung her head low. Grace they weren't really vitamins were they? No Brian I'm sorry but I was so mad that you got all of the money and I thought I was going to blackmail you into giving me the money but they didn't work. Oh yes Grace they did work because I switched them out with real vitamins the one's that you have been taking are Not vitamins as such but what they do is that they change a person from a female into a male, sort of! What do you mean Brian you mean that I have a dick? Of course you do how else did you fuck Mary? Oh my God Brian why? Well at first I was going to change my pills to regular vitamins and we would both be taking regular vitamins. I got to thinking however when you were a good year ago you were a mean scheming bitch only looking after yourself so I decided to make a lesson ought of you. The vitamins have changed you and given you a dick however you still have a pussy. But that was the vitamins, the tea you have been drinking is addictive and wears away at ones will power and in the end makes them a slave to a person who is there Master and that Master is me. Do you understand Slut Grace or shall we say Greg! Oh Brian how could I ever been this mean to you to make you mad at me? Let me tell you slut tonight you will be as you always have been a total slut and when I tell you to do something you will do it do you understand? Yes Master. We pulled in and went to the door and there were two security guards who were patting everyone down looking for weapons. They looked at me and her and I gave them a slow wink. Ah miss you'll have to step over here so we can frisk you, do it I said. Yes Master she said quietly. The guard looked at me and smiled. He began frisking her his hands slowly rubbing her entire body. Then he came to her skirt and he started to run his hand under it and found her pussy and slipped a finger in and he moved his hand and felt her rock hard cock! He stopped immediately lady you're going to enjoy tonight as he smiled she straightened up and he caressed her ass. Nice equipment he has there he said smiling at me. Actually I spoke up he is not a he but a she! The guard was stunned you mean she was born with a dick? Oh goodness no she has been taking a special type of vitamins for over a year and she now has a nice fat cock that works in every way. How did you know all this? Did she tell you? No actually she is or was my sister and I came into money that she thought she should have and tried to do the opposite to me. And I decided a little payback was in store. You mean she is your sister? Not anymore she is just a slave now to do as I please with. Do you want to take a break and find out how good she is? He George I have to take a break been on my feet to much. Sure go ahead Grace you follow him and do whatever he wants. Yes Master and he led her to the bathroom. That night Grace perform for all the men women and the "others" like her. She took on all comers she must have been fucked in the pussy and ass at least a dozen times and sucked more dicks and licked more pussies than I even counted. She fucked all six women there and two she males. She couldn't make it home so I took her to a sleazy motel and put her in a separate room for the night. Outside were several teenagers as I went outside they told me how lucky I was to have a sweet piece of ass like her. I told the three of them about her unique equipment. They burst out laughing and told each other "I'd like to see that". I handed them the key room 124 boys have fun and she likes it rough so don't bother making each other wait just all of you rape her believe me she'll like it. They smiled and headed for the room. I waited a couple of minutes and went to the door and I heard them in there grabbing Grace get that cute dick and pussy naked or we'll rip your clothes off and lock you outside naked and abused! I heard her stripping off her clothes and then how they were throwing her down and taking it to her. I left and went to another hotel for the night, I got up late and had breakfast and went back to the room. Grace was there tied to the bed completely naked with dried cum all over her. Did you enjoy yourself last night dear? I'm hungry do you want something from room service? I'll bet you could do with some I'll just order it and they'll bring it to us. I picked up the phone and asked for some breakfast and a young boy brought our food. I didn't bother untying her. He walked in with the cart and saw her, he was shocked! I looked at him don't worry she won't bite she licks real good but never bites. I took him by the hand and brought him to Grace. This is my homemade slut she does everything and does it without question. Isn't that right Grace, Yes Master. Tell this boy to let you suck his cock. Please climb on top of me and let me suck that beautiful young man meat. She didn't have to say it twice. He was on her with his dick in her mouth so fast. He shot his load in her so quick. Get him hard again slut! And I released her from her bonds. She was sucking him till he was good and hard, alright get on top of that boy and fuck his brains out and do it Now! The boy got his brains fucked out of him she was his first for until then he was cherry but no longer. He walked out with a good tip and well satisfied dick. We heard another knock and I went to the door. There was a women of about forty there and she said. I heard from a friend at the club she goes to that there was a new girl with "special" equipment and I was wondering if she had left town yet. Well not yet but she does like parties are you having one she saw Grace standing naked behind me with cum dripping down her leg. Oh yes definitely. I opened the door and she went to Grace and grabbed her. They tell me you're a slut I like sluts. I looked at them, you to seem to want to introduce each other. This my dear is my Slut Slave Grace but I like to call her Gregg. I turned and left. That night we went and stayed at the women house. I don't remember her name or the dozen or so other women that dropped by for a little but Grace did me proud by taking any and all anyway they wanted it. We started going to the club at least once a week but we stopped by Mary's shop every other day and she was beginning to become like family. We started having "home parties" for a select few and Grace was having the time of her life I kept feeding her the "vitamins" and she kept drinking her tea. She was growing larger and falling into complete and utter submission. The End.
