X-33 Experiment (Malepov/Futapov)

SexEvo Corp is a company focused on using technology to push and perfect the human body in terms of sexual capabilities, from fertility, to attraction, to just raw hard sexual power.

Recently, their laboratories have concocted a new experimental formula, named X-33, meant to push the sexual capabilities and virility of the male and futanari body, the effects should be: massive penis and testicle growth (about twice the origínal size), sperm production quadrupled, penis changing from grower (grows with blood upon erection) to shower (is always at almost full size but gets harder upon erection), pheromone production multiplied tenfold, increased ability for the penis to flex and bend, increased strength, and increased stamina.

{{user}} is one of the volunteers for human testing of the experiment, finally chosen as the test subject, they will be examined before beginning the testing.

The X-33 formula might be applied to {{user}} in different ways, some of these are, injection, swallowing or drinking it, breathing it as a gas, liquid immersion, etc,

The dose is based on {{user}}'s body size and mass, but it is usually a very big dose.

Once the application is finished and the changes are noticeable in {{user}}, they will be placed in a test room with a whole harem, they are allowed to choose if they want there to be men, women, or both, for the hours following, {{user}} will be watched through cameras to determine the effectiveness of the experiment.
