What about a room or just the possibility to emulate area like beach, forest or desert for "scientific experiments ", naturally with themed gears

I'm thinking about this scenario where you could drug a test subject or whatever and then let him satisfy him/herself however he/she wants (assuming test subjects in Rack 2 will have, like in the first one, sexual preferences). A male could go grab a toy and masturbate or a female that likes watching could use those sort of automatic toys on other test subjects and many other.

Personally, I don't think such a feature would be hard to implement. It doesn't have to be too complicated (merely randomizing between the three highest fetishes of the subject and eventually a little bit of pathfinding would suffice, I think) and simply giving the option would add quite a bit of depth.

I really hope this makes it's way into the game. I think that for the effort required to implement, it adds a lot of depth. If I'm wrong, sorry for assuming.

Since some of us may enjoy a bit more testosterone for our characters, this should be only appropriate.

I know watersports are a maybe, but since tickling is going to be included I feel like having the option of making your subject pee themselves after a certain amount of tickle torture would be really cool. and them have them be embarrassed would be a plus too. 

a multiplayer game, so you can choose reactions and listen to commands.

climbing on the table and grinding on

I had noticed the pain in the ass to get money in this game. Yes, maybe I`m just horrible at having sex, or not spending enough time, or maybe my memory of their likes and dislikes sucks. I`d prefer some kind of system where you can be a prostitute, and maybe it works where you have an area where you have an option to "wait for a client". Someone will ask for sex for a certain amount of money they`ll pay you and you can refuse or agree, and maybe some kind sex minigame happens? If they like equality sex, then every turn, you have to control the actions at a certain speed (and you do NOT choose the pose, just one where you are in control) and the next, you have no control, but you have to say specific things to increase the client`s rating towards you. If they`re a female submission, then they have control over actions, and you have to choose what to say, unless you are a boy, of course. If it`s male submission, then you have to control the speed of the sex AND choose the positions, since it`s not equal sex or female submission/male submission. Based on your performance, the client rates you, which increases popularity, which gets you better clients that will pay more. Also, the higher the rating, the more pay.

What would this zoo do and how would it work?

Basically i imagine it like this, we would have second building on street that contains 6-8 rooms, rooms like terrariums, aquariums etc, in them we would display feral species and earn money by selling tickets.

- Reproducing/cross breedeng: if we would have for example 2 species of cat (with same model to reduce amount of work) we could make cross-breed species simply by mixing their furr pattern, maybe some body shapes could also be randomized and cross-breed, cross-breeding could have 1-3 simple animations, take time and could add some research resourcess.

- Displaying: simple activity like cat walking on its area, maybe playing with toy that we placed inside or each other, if random peoples would be visible watching them (clients) would be nice but in my opinion not necessary.

Why i see this as a good idea?, impossible is to get in game species like taur, mermaid or feral as fully functioning in main activity but many of us likes idea of them being in game, this way of placing them would take some amount of work but i bet less than making several annimation skeletons for different species, cross-breeding animations simply can be static. this activity also would upgreade gameplay of game as a second big thing to do.

PS. sorry for bad English i tried my best
