Yes, I am into the macro fetishes. But I really like the idea and unfortunately I don't see it around too often. Basically... you fuck and after you come, you grow. I know it could be really hard to get it implemented but I believe there are a lot of people out there that would really enjoy this.

I'm suggesting this for the more science type people like me. I was thinking for species like reptiles, birds, or any other species that would have a cloaca, have the editing option to remove the balls of males and make the penis internal until arousal.

Boob swing and jiggle needs to be enhanced.  A big boobed character mounted in the stock rack should have her tits swinging all over the place when being fucked.

For added decoration and for a practical purpose:

Some NPCs give you a limited tutorial on what to do in the lab. However, for further and more detailed instructions, the player can go to a small library (or in your office or an employees' lounge instead) to read up on instructions on the game. Plus you can read about how research is done, the 6 elements used for research, and a catalog of how much of an element is normally found in each species, such as horses, bovines, and deer having much more equimine than canines and felines, but have less felinium or caninium than canines and felines. Birds, dragons, and gryphons should have much more avium and scalium than mammals, but have less of the other 4 elements in comparison.

Or planting your face and moving around in the subject's boobs or chest.

The ability to alter the various currently existing fluff on your fur as well as to add hair styles would be fun.

Even it sounds a bit odd, I am missing a vital part of science aspect, collecting data about the subject and not only the chemical components.

I'd enjoy a function that creates a data sheet that saves data on subjects you have worked with.

Next to a nice view of the subject it could contain useful info as:

- Number of sessions and orgasms

- How sensitive the body parts are

- Response and component output to specific kind off interactions (maybe a simple circle or bar chart)

- Information how you changed the body of a subject with permanent effects 

- How satisfied a customer was with the treatment in the last session

With that kind of info it will become a lot easier to favorite subjets when they are paying for you service or when you want to harvest a specific component.

As there is allready a ingame-model for desktop-pc, implementing a function like that would make it a useable tool.

Also information that was learned in the tutorial could be saved there, so you can look it up when you need to. I have to admit I have troubles to remember the meaning of the symbols on the subject selection screen, or what all the graphs on the display mean. 

My options request is mostly with mouse/rat in mind, knowing mice/rats are popular creatures of science and are probably going to get Character Created a lot. I'll go on to suggest maybe even EXPANDED rodent/marsupial genitalia selections to include less well-known and more unique shapes instead of the usual feline/canine/horse/reptile/human. Echidna penis with its four heads, sugar gliders with its bifurcated penis and cloaca, etc.
