hire characters for accompaniment when interacting with the test subject, allowing an automation of two functions, example: the employee massages the subject's breasts while we perform cunnilungius or creating substances with research points automatically

You can make some small crests using fins, but making frills (like for a ceratopsian) with what we currently have is very difficult. It would be nice to have a frill or two to work with and some actual crests to make our own dinosaurs or exotic dragons with.

Placeable cameras[regular and concealed].

If a subject is nude while it knows it is being observed by a camera, it can gain pleasure via the exhibitionist fetish.

VR-glasses are a wearable item that show the subject wearing them the view from a camera, allowing it to gain pleasure via the voyeurism fetish[especially if the camera in question is a concealed one]. Which camera's feed the subject sees is determined by the player.

If a subject is wearing VR-glasses, it cannot see its local environment(duh).

If the player wears VR-glasses, move the view to whatever camera's feed is shown.

[the cameras' views don't have to be rendered unless the player is looking through them, in which case the player's 1st/3rd person view does not have to be rendered (especially since rendering multiple views in realtime is performance-heavy, and might be nearly impossible to implement depending on the underlying game engine)]

Optional 1: "streaming" a camera feed to earn a little bit of money on the side

[perhaps in the form of minor goals(that might not be what the subject likes)]

Optional 2: camera contact-lenses

A wearable that records/streams the point of view of the wearer. Counts as concealed to any subject that couldn't see them being put on.

A rack upgrade that automatically keeps chemicals in the subject's body at the desired[user-controllable] level.

If there is not enough of a certain chemical in the subject's body, it will automatically inject more, provided the user has the required chemical.

This is especially useful for chemicals that wear off over time.

If a chemical and it's nul-form have effects that cancel each other out, allow the user to set a minimum and maximum level:

If the subject is below minimum level inject the chemical, if it is above maximum inject the nul-chemical, do nothing if the subject is in between.

To me personally Ma'am isn't as sexy as Mistress , the male preference get's Master so why not \,._./

Can you add some monster girls to game like nekomata (Cat Girls) and others, this's totally counts as furry but not fully zoophilia which is liked by a big fan base and it will be really awesome if you at least 1 monster girl specie to your cool game.

I would be good to have the option of painting the subject's claws/nails of any color and maybe some patterns

Feed test subjects to make their bellies grow. 

Once you've got a couple of coolers, a full tank of Specimen takes like, 8 minutes to process, and you can't be doing research during that time. I'm also not sure how it interacts with when you're actively "experimenting" on somebody.

That 8 minute gap in gameplay is kind of a bummer, and spoils the pacing. Just some way to upgrade the processing time would be great.
