A concept I've seen a couple times in images or stories is the idea of pleasure/orgasm transfer, where although one person is pumping away at their genitals, all the pleasure is going to the other person, while they feel nothing or feel a lot less. This idea could be incorporated into rack 2 through an orgasm transfer ring. Say subject A is male, and subject B is female. You could put the input ring on As cock, and the output ring on Bs clit. Start pumping away at A, and as he gets closer B is getting more aroused. When A reaches orgasm however, even if you keep pumping, his incoming pleasure immediately drops to zero. Meanwhile B has a spontaneous orgasm, and whatever movements you are still doing on A, the pleasure is transferred to B. So basically you could have the male hit orgasm but then not actually get to have an orgasm, or even make him have a ruined orgasm, as all pleasure has stopped once he's hit the point of no return. Meanwhile the female is having a wild orgasm, squirting all over the place without any actual contact.

Considering all of the hard work you've been putting into this game i'll understand if these go unnoticed.

Certain actions should have a different means of control , spanking or smacking as well as future and current breathplay actions should be a click and hold instead of circling the mouse like a mad-man. Whether it be RMB or LMB with that action is up to you if possible.

Facesitting is a form of breathplay , some people are wanting flatulence to be in the game but sniffing is pretty similar IMO. The facesitting action would be

1:Sniff

2:Sit (oral more or less)

3:Smother

Plus choking is a pretty common fetish (dunno if it's in the game already or not) 

Hand 'tool'

1:Squeeze

2:Choke

An apology option would also be nice as I suck with my mouse and end up hurting clients on accident ;-;

Annnnnnd there are some freaky bugs in character customization , but i'm sure those have already been reported.

I know someone else suggested it 3 years ago but just want to bring more attention to it. The ability to hear the subjects heart and/or see it on a heart monitor would be a neat thing to have since it is medical related!

Add a rack that is basically the table rack, but it's in a vertical position

describe itself but like a chimical like the gigasol but targetable

To be honest there might already be a way and i'm just too stupid to figure out how.

But at the moment if i tell a subject to for example call me sir there is no way to undo it and make them talk normally again, as far as i know at-least, if there is a way that i am missing please comment how

for stuff like this 

and then the tail tip would be a layer over it for dyed tail tips

Once you've done all research you care for at the moment, the leftover chemicals will be virtually useless. And it's not like you are going to stop working with subjects just because their samples are of no more use to you right now, that's not what this game is for. Now, you could, of course, just sell it into the market and be done with it, turning the surplus into cash the most boring way possible.

Or.

You double the area of one of the test rooms in the direction away from the elevator and install a one-way mirror where the wall used to be.

You set up a lounge on the other side, with dim lighting and hookah and an extensive list drinks, including cocktails with some special ingredients mixed in (leftover samples are still digestible, after all).

On your side you place several racks with subjects, possibly of different species and genders so as to cater to everyone's taste (volunteers or research subjects, since having them pay you for this type of employment would feel wrong, those who are willing to participate so much they are willing to pay for it can just sign up as volunteers).

You decide on working hours of the lounge, set hourly rates for visitors (with drinks possibly made complimentary or setting a quota of number of drinks per hour per person) and either tend to subjects yourself or assign your lab assistants to do it instead, possibly training them individually beforehand in the art of getting the most out of those locked up.

*Training would, of course, include having several sessions with your assistant acting as a test subject, or vice versa, or a mix of the two, or them observing your work with regular test subjects and taking notes; breaking them into complete submission, making them obnoxiously dominant, guiding them through altering person's preferences via chemistry or hands-on interaction, etc. You know, fully introducing them to what this lab is capable of.

For flavour, you may want to turn a couple of sections of the mirror into revolving panels and place portal devices on them, with, for instance, a couple of male horse-morphs connected to the devices, edged by machinery throughout the opening hours, their dicks producing a steady flow of precum. Metal or ceramic trenches can be installed just beneath the panels, extending at a slight incline to individual sofas, so that your visitors can freely help themselves to it. Requests to increase the stimulation to finally let them cum can be either accepted at a fixed price or auctioned off for each subject individually, with the winning bidder deciding on how exactly, if at all, they will be brought to their orgasm at the end of opening hours.

Add some sexy downtempo in the background, decide on dress code for your clients, and don't forget to assure them they can be as frivolous as they please (after all, the fun does not have to be limited to the opposite side of the mirror), and that spontaneous orgies are welcome here. Some aphrodisiac in cocktails may serve as a stimulus for them to do whatever they want to.

This way, you still turn profit from your surplus of collected chemicals, but extract some amusement in the process.

This is an endless pain to code though.

cum storage for both genders to sell or use or for impregnation or  for your character to drink to boost their refractory rate and quality.  

To be able to create mushroom penis for humanoid options or not only for them
