so I was thinking an thought there would be nice to have a machine that moves the subject. This machine could work by having a pinch grip that you can place You could use it both to move a subject to fuck another subject, moving the dick or move the hole of the subject (pussy, ass or moth). This machine could work by having a piston and on that a pinch grip that you can place on the subject (not hard). You could place it on the back of there head, on there hips both front and back depending on  what you want to move (dick/pussy, moth or ass) . It would also be interesting if you had some more racks to go along side this machines like one where the subject kneeling down one were the subject is just staining straight or a T pose and lastly the X Rack one. Perhaps they could be on wheels or something to move them into place?

Because of a games limited programming there tends to be an overlap for when you have a cool idea for a way to use a "tool" for a purpose it wasn't made for that often can't be used in that game, and I was just hoping that you could make a way to have more "creative" uses for items that not everyone would think of.

In the original Rack I liked how you could change the environment from a Lab, to underwater, to a crowded area, to space, etc. I mean I get this is all about lab environment bondage, but it would be nice to customize the lab a little more with this easy feature.

What this does is it adds these 2D panels that can be put on walls (or set up as their own mini wall if you want to section off parts of a room) These panels can then be changed to show different Scenery and if you map all the panels together you could get a very realistic 3D scene using 2D panels.

Now there are different ways of doing this from putting Looping Animations of random scenery on the Panels to actually designing a 3D Environment and reflecting it on the panels. 

This idea is just a little... spice things up, kinda thing. Lab settings are nice, but it is a game about experimentation. Now something that can be added to go with the 2D Environmental panels are "Skins" for the different equipment to change how they look, do you want equipment that looks like its made from wood, or maybe... tentacles? lol You could even include an antigrav system which works with the cum mechanic, making all the fluids float around (Like in the underwater/space environment in the original Rack)

Now I put this under fetish and Sex toys because it does relate to both. 1 it offers new appearances for sex toys and such in general. 2 Fucking in random places is a fetish that can be simulated with those panels. Antigrav and space theme... be epic lol.

You should be able to pour wax from a candle onto the test subjects.

A sexual characteristic slider that determines how erect you character (if you have a penis, of course) can get. For example: If the slider was all the way to the left, the character would not be able to get it up at all, and so on and so forth.

Though this has been posted before, It's not in the list of fetishes so I thought it should be re-introduced.

for they can fuck theyselves

Something to make the subjects dumb and kinda babble submissively? Maybe drool on themselves, tongue hanging out. Stuff like that?

being able to replace parts with robotic/cybernetic equivalents. Not like dismemberment, which I know has already been denied, but being able to say that my leg is a horse, cat, bird, or cyborg.

I would like I suggest a weight gain serum or injection, or perhaps a good old fashioned force feeding mini game.
