And by "liquid on camera effects", I mean sperm should start swimming across the screen should the camera pass through a puddle of semen.

And that the sperms should have the head of whom ever ejaculated that puddle.

You've got to set up six genital portals on six subjects, for Reasons (could be anything from another scientist doing long-distance experiments on the subjects to a company party using their junk for dipping sauces; who knows!). Your job is to soothe the subjects on your end so that they remain content and willing during the experiment; you can use dialogue or massages or whatever. Your job gets easier if you can figure out *what* is happening to them, so there's sort of a science-y element to it!

The tour of the lab is all well and good but it gives very little information on how to actually play. The visual ques the game gives when having sex doesn't mean much if you don't understand what any of it means.

Penis above the balls like a kangaroo

the ability to combine the genes of you're self, and one(or more)subject's and implant the embryo in either a female/herm/cu/other's ovum/womb

alternatively, you would have the option to sew, fuse, or other wise, combine two or more subjects into one.

with this feature you can create things like two headed dragoness's, or multi-limbed lioness's ETC

with dna editing, you customize physical attributes such as height, weight, species, sex, facial features, bodily features, sexual features(will his jizz be green and glowing or a dull pink, will she have live births or lay eggs, how many breasts will he/she have, how many testicles, how many ovaries, how many penis's, ETC)and phsycological attributes, like sexual preference, sexual interests, and many more!

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

That first one surely could be very productive! But what about the second? or third? Or tenth? A dribble of prostate fluid after multiple orgasms seems to add some realism! 

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.
