Karen and the Formula

By Muscle Admirer

I guess in life it really is who you know. My mother works for twin labs research and development and that is how it all started.

My name is Karen and I am 18 years old I currently live at home with my mother Tara and little sister Nikki who is 15. My mother is short an petite and so am I and my sister I stand 4’10 and weigh about 90 pounds (actually 89 but who cares). My mother is 5’ tall and weighs about 100 pounds. My sister Nikki is about an inch shorter than I am and weighs about the same as me. The only advantage is that I have a great face and personality. Physically I have always been pretty weak and pretty flat-chested. Actually my mother said I looked like Olive Oyle with Stephanie Seymore’s face. I always wanted a better body. I really envy female athletes and bodybuilders but my metabolism is so fast when ever I tried to put on a few pounds it always disappeared. Even with the products my mother used to bring home from twinlabs, they never helped.

One weekend I had nothing better to do so I went to work with my mother because I like hanging out with her and seeing what she did at work. While she was filling out her afternoon paper work I decided to go wandering around the complex. That’s when I found my salvation. I was going down a corridor in the new development area of the building when I saw a secure closet that was used for the storage of newly developed products was unlocked. The red light on the security panel was on but the door had not closed all the way. So, I walked in to see what they kept in there. Inside were rows and rows of different boxes with different labels on them and on the end of each row was a clipboard with an index. Going thru the list I saw the newest line of protein drinks and weight gainers then on the last part of the list was the untested section one thing caught my eye it read SUPER WEIGHT AND MUSSLE MASS FUEL FOR WOMEN I figured it was just what I needed so I figured I would take a couple of packets to test them out. On the box it said the product would not be tested for another year. So I took 24 packets and one of the instruction manuals.

Later that evening when I got home I read the instruction manuals and discovered I had taken enough for 2 years each packet was good for a month. Reading on I also discovered each packet contained 30 capsules, I was to take one capsule each day. I was also to let my body tell me what to eat and if I was hungry I should eat. The formula sped up the persons metabolism and allowed greater food consumption while it processed the nutrients from foods better causing the person to retain muscle mass. So I decided there was no time like the present. I took the capsule dissolved it in milk and drank it. Before I went to bed I weighed myself and took some measurements and put them in a book so I could keep track of my progress as the instructions recommended. Needless to say I could not wait for some improvements my exact height was 4’10" my weight was 87 pounds my chest was 30" waist 18" and hips 24". The next thing to measure were my limbs fully flexed. My biceps were 8" my thighs were 15" and my calves were 9". After this I felt pretty wimpy so I went to bed and hoped that this stuff worked.

The next morning I woke up very hungry so I went down stairs and had some breakfast but instead of the usual toast I had 2 scrambled eggs ,6 strips of bacon and 2 pieces of toast. This was the biggest breakfast I had had in a long time. My mother was up and she commented about my breakfast and I told her I was trying to put on some weight again for my boyfriend Jim. I also told her I was going to jog over to Jim’s house to workout with him.

Jim is my boyfriend we have been going out for about a year. I knew him since High school we were in band together, he was a senior when I was a freshman. He’s now 22 and is just about to finish college. I met him at a party of a mutual friend and he asked me out. His parents died about 2 months before we met and left him a huge inheritance, a couple of million dollars from what he tells me. I like Jim a lot I think he’s funny smart and has a really cute butt. I think another reason I like him is because physically we are similar. He is about 5’6" and weighs about 135 pounds. He tries to work out and put on muscle but he just doesn’t have the time or will power. In fact recently he has gotten a little pudgy around the middle. He also has a thing for strong women, I can tell by the way he looks at the muscle magazines and he is always trying to get me to work out with him and he is always feeling my biceps and commenting that he would like me with a little more muscle. I also know he would like me to have a little bit bigger breasts. How I know this is that recently just after I had turned 18 we had sex for the first time and when he saw me nude I could tell by his face that he was disappointed although he would never say anything to me which is another reason I love him.

I had run over his house before it is about 3 miles from my house. About half way there I had to stop because of stomach cramps and walk the rest of the way. When I arrived I knocked on the door and then let myself in. Jim was still sleeping, after all it was Sunday morning. He heard me coming, and yelled that he would be down in a minute and asked if I would cook him breakfast. Which sounded like a good idea to me because I was starting to get hungry again. When he came down stairs and saw me in my cute little shorts and T-shirt he came walking over grabbed me and said "you look really sexy in that outfit. I take it you’re here to work out."

"Yep, do you want to work out with me?"

"Sure, just let me eat and then I’ll go change and we can work out."

While he was eating I had another piece of toast and a glass of juice.

When we worked out I didn’t notice anything special as far as weather I was stronger or not. Afterwards he challenged me to an arm wrestling match with the condition that the winner got to do anything they wanted to the loser. I agreed hoping that he would want to have sex when he won, which he did. I told him that I was starting a new workout regimen and that he would not be winning at arm wrestling much longer unless he also started to work out too, to which he laughed and said he would never have to worry about a shrimp like me.

"That hurt." I said. Which it did.

He apologized and then made up by making very passionate love to me after he beat me at arm wrestling.

When I got home later that afternoon I found myself hungry again and I could hardly wait for supper. I had to have something to eat so I snacked on some protein bars that my mom had lying around. That night at dinner I had seconds for the first time since I was a kid.

That night I eagerly measured and weighed my self only to find no change what so ever I was kind of disappointed but then realized that it would take a while for me to see any results. So, just like last night I mixed myself a drink and then went to bed.

The next morning I found myself waking up very hungry again so I ate another big breakfast and went to work. I have a job at guess what, a health food store (go figure?) courtesy of my mother. At work I found myself hungry all day long. I ended up eating a whole bag of potato chips during the course of the day. That evening when I got home I found myself overflowing with energy so I figured I would use the gym in our cellar as opposed to running over to Jim’s again to workout. I worked out pretty hard even for me and after I felt great.

This went on for a month. During the month I found that I was indeed slowly putting on weight, about a pound every 3or 4 days. At the end of the month I found myself about 10 pounds heavier and an inch taller. Jim did notice too he said that I was finally starting to fill out in the right areas. Meaning of course that my chest was a little bigger, although I could hardly notice. Looking in the book I did notice some of my measurements had changed, not much but they had changed. I had added 1/2" to my biceps and almost an inch to my chest and thighs. I was very excited, especially about the inch I had added to my height. I thought this was great and hopefully I would see more.

Over the next month I put on another 10 pounds and another inch in height I was now up to 5’1 and my weight was up to 109 pounds. I could also see a small peak forming in my biceps and I had gone from and A cup to B cup in bra sizes.

Jim was very excited also he had noticed that I had grown in height and weight and was providing only positive reinforcement. He told me to keep doing what ever I was doing because I looked fantastic and it seemed to be helping with our sexual relationship, not that it needed much help in the beginning. I had noticed the that I was becoming strong too. The weights I was using on the home gym were heavier and I was able to use them for longer periods of time.

The next time I worked out with Jim was a lot of fun too.

It had been about 3 months since I had started using the formula and I was about 5’3 and 120 pounds. Three inches shorter and about 30 pounds lighter than Jim. He had put on about 15 pounds since I had started my regimen and none of it was muscle. We had begun to work out when he noticed that I was using the same weights that he was.

"What’s this?" he said.

"What do you mean, honey?" I said knowing what he meant.

"Have you gotten a lot stronger or what?" Jim said.

"Well" I said "for the last three months I have been working out almost every day and you have hardly lifted anything besides a potato chip. Of course I am going to get stronger while you won’t."

"How strong are you going to get." He asked.

"I don’t know. Do you mind that I’m getting stronger?" I asked shyly.

"No." He said "In fact I’ve always fantasized about strong women and I’ve even though of you growing stronger."

"I know, I’ve seen the way you look at fit women and now I will be one of the women you fantasize about."

"I love you." he said as he gave me a big hug and kissed me.

"Do you want to arm wrestle me now?" I whispered in his ear playfully.

"Sure, lets do it."

"Standard bet? Winner gets to have the loser do what ever they want." I asked suggestively.

"Sure." He said as a grin slid across his face.

When we put our arms on the table his eyes stared at my arm noticing the considerable peak that had developed over the last three months compared to what it used to look like.

"I think it’s almost as big as your arm is." I said.

"Yea. It looks it." He replied.

When we started wrestling I was not sure who would win, it seemed pretty even. After a few minutes he eventually pinned my arm, but not without considerable strain. He was sweating a lot, like he had just run a few miles.

"Wow that was really exciting. I wasn’t sure I was going to win there for a while. I am really turned on right now." He said.

"I can tell." I said as I looked suggestively towards the bulge in his gym shorts.

"Well let’s not waste all this energy. I want you to do a strip tease and show off your new body to me." He said.

"My pleasure." I said, feeling as aroused a Jim was.

I started by dancing around him while he was sitting on the workout bench flexing my biceps. After a second he said "Wait here a second I have an idea." And he ran upstairs and came back after a few seconds carrying a sewing tape measure the kind used by tailors to measure people for suits. "I want to find out how big you are." He said as his eyes looked me over with excitement.

"Make a muscle." He said. "Ten inches, that’s pretty good for a girl your height."

Jim proceeded to let me measure his biceps. "Eleven inches, looks like I’m gaining fast Jimbo. You better start working out or prepare to have a girl friend that’s stronger and bigger than you." I said playfully flexing my biceps in he face. To which he started kissing my biceps and then moved on to other areas.

The next two months I didn’t see Jim at all. We talked on the phone a lot but he wasn’t able to spend any time with me because of all the final papers and exams he had to get ready and he told me he couldn’t have me around because I was too much of a distraction.

Jim called me and told me he wanted me to come over for another workout the weekend after he finished his final exams. I couldn’t wait for him to see the changes I had gone through. I showed up that Saturday morning and knocked on his door and waited for him to answer. When he opened the door I wished I had brought a camera because his expression was great his jaw just about hit the floor. When I stepped inside he hugged and kissed me saying that he couldn’t believe it was me and that I had changed so much and become so beautiful it was unbelievable. I was now into the 5th month of treatments and I had grown to a height of 5’6" and weighed about 142 pounds of mostly muscle. I was now a 36c bra size and filled out my workout shorts and T-shirt to the max. Jim had to sit down he was so shocked.

"You are one of the most beautiful women I have ever seen in my life." He said obviously meaning it.

"And your one cute pudgy guy. Come on lets go work out I can’t wait to show you what I can do."

When we went down to work out I could tell that he was a little excited by the way he was looking at me and in the way he was not saying much. I really wanted to find out how much I had grown in comparison to the last time we worked out together.

I started first with 40 pound arm curls.

"Don’t you want to warm up first?" he said "You don’t want to work out with your maximum right away, right? You should really do a warm up first so you don’t hurt your self."

"This is my warm up weight. I told you I have gotten a lot stronger since the last time we worked out together." I told him as I finished off my first set of 14 reps. "Your turn." I said as I stepped out of the way.

He looked a little worried as he started his arm curls and he did not change the setting on the machine. I knew he was probably doing this so he would not look too bad. As he reached his 10th repetition he paused visibly tired and pumped off one more and then half way in to the second he let the weight drop. "Whew, I am really out of shape. I used to be able to do that much weight. I didn’t realize 3 months off could have such an effect on me. And you, you cranked these off like they were nothing."

We continued the work out with Jim reducing the weights he used by about 50% of what he did the last time we had worked out together. At the end he seemed a little depressed.

"Don’t feel bad honey." I said consolingly. "I’ve been working out a lot lately"

"I know, it’s not that. It’s just that I hadn’t realized that I had let myself slip so much and compared to you I feel like a wimp." He said. "You look so beautiful and strong now I’m just afraid that I’ll loose you because I’m in such bad shape."

"Not at all honey, I don’t mind that you’ve let yourself slip a little you can get it back if you want to. I kind of like the fact that the tables have changed." I said with my best seductive voice. "Do you want to arm wrestle, the usual bet?" I said as I sat down at the arm wrestling table we had setup in the basement, it was actually just an old card table.

"Sssure." He said as he sat down across from me and we locked hands. "Start when ever you want." I said.

I could tell even before we started that Jim would loose. I could see that he had lost a little muscle mass as well as gained some weigh over the last three months. His arm was now visibly thinner than mine and when we had grasped hands I noticed that nothing happened to his biceps when he clenched his fist. Where as my arm had a visible bulge in the biceps even when my arm was relaxed. When he started I could see and feel the pressure he was exerting. He was really giving it his all. I could feel his arm pressing against mine but I knew that he didn’t have a chance. I let him bring my arm down a couple of inches and then stopped his progress. After about 10 seconds of Jim straining against my arm I started pushing his arm back and I kept pushing until I had pinned his arm to the table.

"I won, I won." I said excitedly as I jumped up and down and hugged and kissed Jim.

"And what does my beauty queen want me to do for her?" Jim said as he flourished a bow.

"I want to compare our measurements again." I said grinning broadly.

We started with height. I measured 5’6 1/2" and Jim measured exactly 5’6".

"Hey I’m taller than you now, how do you like that? I’ll have to start calling you shorty." I said with enthusiasm as I patted him on the top of his head.

Jim gulped as he looked at me with wide eyes.

Next we moved onto biceps mine measured 13" to which Jim was very impressed. I could tell by the way he seemed mesmerized by my biceps and the way his hand was shaking. His arm on the other hand had shrunk from 11" to 10". I could tell that Jim was very turned on by what he saw.

"Don’t worry honey." I said. "I still love you even though now I’m bigger and stronger than you."

"I know you do, that’s why my hands are shaking. I’m just really excited about all this." He said.

"How is all this happening? How tall.. errr...big will you get?" Jim said tentatively.

I told him about the untested formula I was taking. I also had some other things to tell him about. After I had started growing so much my mother had found out that I had taken the experimental formula and stopped me for a while until she had some time to research exactly what I was taking. After about a week she told me that it was ok and that the formula was made using mostly natural ingredients and that it was most likely harmless. I think it was because she also wanted to start taking it.

A month or so after she started taking it she took a research sabbatical from twin labs and started producing some of the stuff in our basement and now had herself and my younger sister on the stuff. That was three months ago.

"So I guess it’s kind of up to me as to how big I want to get." I told him.

"Your mother and Nikki are going to start getting like you too?" he said with an astonished look on his face.

"They already are and you can already see some changes. Not so much in my mother, because she is older I think, but you can really see them in Nikki." I told him. "She is almost five feet tall and a little over a hundred pounds. She and my mother have been working out with me for the last three months, Nikki a lot more than my mother. All we bought her for her 16th birthday last week was clothing, because she has out grown all her old clothes."

"Wow." Jim said. "I can’t believe all this is happening."

"Neither can I. Isn’t it great?" I said as I closed the distance between us and put my arms around Jim and kissed him passionately.

Sex that morning was the best ever. Jim worshipped my new body and I could tell he was anxious to see how I was going to develop.

Over the next month I grew an inch and a half in height making me two inches taller than Jim. I kept growing in strength too. I did get Jim to start a work out regimen. He stuck to it too. Now that he was through with his finals he and I were able to spend a lot more time together. I worked out as much as I could with him and also with my sister Nikki, which some times made as much as 8 to 10 times per week. But my body just seemed to take it all in stride and adapted. I was eating so much I could not believe it my self. I put on a good 20 pounds of muscle during that month. Jim on the other hand had lost some of the weight he had gained. He now weighed in at about 145 pounds while I on the other hand now weighed 162 pounds had 15" biceps a 38D chest and stood and even 5’8" tall. This growth seemed to fuel our sex life which was great since now I could not seem to get enough sex with Jim. I loved the fact that I was now visibly bigger and stronger than him and he liked it too.

The next weekend he was out mountain biking and he fell and broke his wrist and ankle. The wrist injury was not all that bad but the injury to his ankle was very severe he had surgery and it had to stay in a cast for about 6 months. After spending a week in the hospital because he developed an infection after the surgery. The doctor said that during the first 10 weeks he would need to have a full time nurse. Even though he had the money I insisted that I be his nurse and with my obvious advantage over him he was not in any condition to refuse. There was only one problem. Two weeks into his injury my mother and I would have to leave him for about 4 weeks to attend my cousins wedding in Montana, it was a very big deal because she was marring a very rich guy out there and she needed us to help plan and coordinate the wedding. My mother and I had decided that it should be ok if Nikki did the nursing for the 4 weeks. Little did I know what a fiasco this would be. Here is Jim’s account of the three weeks with "Little Nikki".
