The lab stuff is already decent as is with the oral opportunities, but hear me out. A milking table. Maybe two versions.

Version 1 is for rimming. And more or less a chair instead of a table. Subject is sitting down, and their junk (balls, penis and ass) is exposed and ready to get "experimented" on. But with a tongue, lol. Maybe with the player just casually sitting back with their arms crossed?

Version 2 is for blowjobs and ballsack stuff. Subject is lying face down, with the sack/penis floating about. Again, ready to be "experimented" on. While maybe the player is on their knees, with the ability to masturbate as well?

there should be pauses in the dialogue with the subject, that is, as if time stopped, so that the robot can explain without being interrupted by the subject

it would be cool if you could make any music play while interacting with subjects or just relaxing

Exactly what it says on the tin. The ability to relocate a subject from one rack to another within a single session would be a nice and simple quality of life improvement.

A menu that can be pulled up to quickly teleport to important areas or access important features to allow a simpler experience. This menu would only be unlocked after completing the tutorial (or in free play) and would include access to the shower, client selection, and research screens, along with whatever else is needed, and have buttons to teleport to each client. This menu would likely be the default screen when pressing Esc.

Fek, I think you should consider about start adding new species to the game. Maybe one new species per update isn't much additional work?

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.
