only exams and instructions

I arrived accompanied by Brooke for the scheduled appointment with Dr Merk, who quickly attended to us.

"Welcome sir. Gloria told me about your situation. It's rare that I see a man seeking the treatment. Usually, not even women come to see me because it is a standard treatment that hardly requires any adjustments, and those who come to see me are only due to insecurities related to side effects." Dr Merk said

"Gloria explained to me that the treatment is very unlikely to work in men. What do you think are the chances of it working on me?" I asked her

"I can't say for sure, because there are really few men who have even tried it and much less who have had results, but I speculate that it's less than a 1 percent chance of something happening." Dr Merk said

"How will I know if the treatment is working?" I asked

"In the first few days you won't be able to tell, so I'll ask you to take new tests weekly. The first signs are very subtle and only detailed examinations with appropriate equipment will be able to tell if something is really happening." Dr Merk said

"Is there anything that can be done to increase the chances of the treatment working for him?" Brooke asked

"Maybe so, but so far it's just a theory that I haven't been able to test. I think that if an extra ingredient is added to the shake it can not only increase the chances of it working, but also potentiate its effect so that the changes happen up to twice as fast as expected. And in your husband's case, he has the advantage of having not only a large stock of this ingredient, but the source of it right next to him." Dr Merk said

Brooke and I thought it might have something to do with her work, something that could be acquired through her company's services.

"What would this ingredient be? I will negotiate with Gloria to buy from the company." Brooke said

"It will not be necessary to talk to her or buy anything. The extra ingredient that must be mixed into the chake is cum from a woman who has had or is having the treatment, the fresher the better." Dr Merk said

"So what if you need to mix some of my cum into his shake? This I can do with great pleasure." Brooke said and looked at me with a smile, which I returned. Just the idea of ​​her own being part of the treatment clearly excited her and I could see the bulge growing in her pants as she got indisputably hard.

"Now let's move on to the exam part. I need to collect data about you, about your physical condition and health, as well as measurements." Dr Merk said. She then took samples of my blood, saliva, hair and other materials from my body, then took measurements of my body. Lastly, she also asked me to cum in a vial for her, as she needed to know exactly how much cum I produced per ejaculation, as the increased amount would be a sign that the treatment might be working.

I asked where for a place reserved for it, but the Dr said I would have to do it right there. I was embarrassed about it, but Brooke encouraged me by saying that she would be with me on this. I was embarrassed at the thought of jerking off in front of the doc, but Brooke asked if she could masturbate with me, getting permission, and said it would be easier if we did mutual masturbation so I could forget for a bit about the fact of being watched.

I took off my lower clothes and Brooke did the same with hers, then I stroked her cock while she did the same with mine to get me hard. With my erection firm, Dr. Merk asked us to stop for a while, so she took the measurements of my erect cock. I noticed she was put off when she measured my 7 inches cock, so just for the record, she measured Brooke's erection, which was now 10 inches.

"Ten inches? It's really big, of course, just looking at it you can see that I don't even compare to Gloria." Brooke said

"Not even close. Your hard cock is even smaller than Gloria's is flaccid. Her dick is 12 inches when soft and grows to 18 when hard." Dr Merk said

"Who knows, maybe mine catches up with hers one day?" Brooke said

"I don't think so. I believe that yours will not grow much more, it should gain one more, two inches at the most." Dr Merk said

"That's a shame." Brooke said and we went back to our mutual masturbation

While we were masturbating, I heard a zipper unzip and saw that Dr. Merk had unzipped her pants and pulled her own hard cock out of her pants. I wasn't all that surprised she had one, since she prescribing the treatment, so she probably had been through the same. What really surprised me was the size of her dick, because as far as I knew at the time, only my wife's dick was growing while the others were already at their final size. I expected that they would all have dicks at least the current size of Brooke's, but Dr. Merk's, even at its final size, was a little smaller than mine, it should be 6 inches long by my estimation.

"You can laugh, my dick is really small. You'd expect that I, one of the creators of the treatment, would have a pretty big dick, but instead all I got was this little thing right here. Okay, that wasn't the intention to make women grow dicks, but since it happened I could have at least grown a bigger dick." Dr Merk said

I thought it was better not to say anything, I just looked at Brooke and she looked back at me, apparently we were thinking the same thing. We continued to stroke each other's cocks as if we hadn't seen a thing.

When I announced that I was close to coming, Brooke grabbed the vial that had been left next to us with her free hand and pointed my cock into it, collecting my cum. I then walked around stoping behind my wife and started stroking her cock with both hands.

"Honey, stop for a while." Brooke said to me and then and turned to the doctor "Dr Merk, do you have a bigger bottle for me to cum in? Guess you don't want me to use your floor, do you?"

"Don't worry about it, the cleaning lady is ready to clean as soon as you're done." Dr Merk said without stopping jerking off

As she ordered, I continued to caress my wife's cock, who unimpeded let the orgasm flow and her cum gushed. In the meantime Dr Merk also came. Her amount of cum was slightly more than mine, but it was still nothing compared to Brooke's.

Once we were done, Brooke and I changed into our clothes and got the final instructions.

"Okay, now I'm going to give you the prescription for the treatment. You will need to take shake three times a day and the dose should be doubled as you are a man, as the change to be caused is more radical that is necessary, and if you want to test my theory on your own Brooke could find a way to come first and mix some of her cum into the content. As for normal food, you can eat whatever you want without restrictions, if you can. The shake should keep you fed and provide enough nutrients that you don't need it, and you may not have room in your stomach for food anyway." Dr Merk said

"And how long will the treatment last?" I asked

"If it works, it will be up to three weeks in a row without registering changes, which will mean that the process is complete. To see if it's working, we'll redo your tests every week, but if nothing has happened in two months, we'll stop, because it will mean that for you it's the same as drinking water." Dr Merk said

We said goodbye and scheduled a new appointment for the same time the following week.
