(This is a custom clip. DM me if you would like me to make one for you!!) The following is a gender transformation story, male to female. -Outline "You are a scientist who has been working on a new range of supplements using cow hormones to help people. The pov signed up to be a test subject for the "bull" supplement, which is designed to increase testosterone and build muscle. You give the pov the pill, and wait a minute to make sure there is no adverse reaction. Fairly quickly, you notice that something doesn't seem quite right as the pov becomes flush and their pants begin to bulge. This type of reaction has never occurred, panicking you take their pants off to reveal a full blown erection. Shockingly the growth doesn't seem to stop. You figure perhaps the pov just needs have some release, giving the pov a handjob, blowjob, tease, etc (however you would like to handle this section is totally up to you). It doesn't take long for the pov to climax, and it seems like things are finally settling down for a moment. Perhaps you get some of the cum onto you, or you come into contact with it while you are collecting a sample for further study, unaware that this cum essentially was the pov's bodys way of removing any masculine hormones, (maybe these hormones will transfer over to your body causing some changes). You then notice that the pov's cock seems to keep shrinking, well below what would be normal. Worried, you check the supplement bottle to find that you did not give them the "bull," supplement, but rather, the "heifer," supplement. The "heifer," supplement was an extra strength product that was being designed to help woman achieve their body goals without diet, exercise, or surgery. You had never tested this supplement before, let alone on a man, so there is no telling what might happen. You then begin to notice the new changes taking place to the pov's body as they begin to shift part by part from a man to a woman. You describe each change as it occurs, shocked by just how quick and significant the changes are. Feel free to go crazy with whatever changes you would like. (Please feel free to think of this a simply an outline, and to change things however you would like. I am always happy to let creators have as much fun with these prompts as they can) -Ending I will leave the ending up to your choice, as it is always fun to be surprised. Just a couple of thoughts, perhaps the pov has other side effects due to the supplement, is the pov becoming a hu-cow? Does the supplement effect their mind in anyway? Does coming into contact with the patients sperm cause any side effect to the doctor, does it make her more dominant or change her body in any way?
