I really like the idea of musk and a strong smell coming off of someone. Something like the subject being noticeably sweaty, dirty, or something like that. Maybe it could go along with smegma, since I like that too, and it kinda makes sense to pair with being dirty. 

The idea is very simple, assuming characters have specific fetishes etc. I want to be able to satisfy characters / discomfort characters and see long-term effects on my actions. Like, if I were to give a girl everything she liked, when I come back she might say, "I was wondering when you'd be back." Or if I were to give her utter hell, she might say, "Oh, it's you again." You might have seen a similar idea on a much larger scale, but I figured this might be a good first step.

I would love to see some more belly-centric interactions such as navel insertion/stimulation with toys or tongue, rubbing, patting/slapping, kneading/groping on sufficiently fat or inflated characters, and possibly expelling cum (or other fillings if added) with applied pressure.

I don't know if Fek is going to add this to the game, but I think there should be private offices for the researchers at Rack Laboratories. You can have some drawers that can store clothes and items, as well as (maybe?) customization of the player's office. There can be a desk with a lamp or computer or something, a window that the player can look through, metal filing cabinets, (maybe?) a directory of your coworkers, favorite clients, shopping centers or nightclubs or strip clubs or supplying providers for the lab or some other place, (maybe?) pictures of random things or clients or random sceneries, http://fek.userecho.com/forums/1-general-suggestions-and-ideas/topics/164-beds-preferrably-without-bondage/ maybe a twin-size bed in the office to lay down on or have sex on (or a queen-size bed (I looked up what is a better bed size for sex and a lot of sources said queen) in your apartment if Fek is considering that too, especially if you can invite clients or romantic interests), and perhaps more.

If there are other coworker offices, can you go into them as well? (though you can't customize those areas)

Should there be a water fountain as well? (lol sex can be dangerously dehydrating)

Should there be a lounge area for the employees?

Should there be a storage room for things you made too much of and can store there instead? (or maybe selling is a better option since you made something and getting rid of it would be a waste)

Just some ideas...

Can we please fix the fact that you have to talk to people to make them friendlier? You’d think giving somebody exactly what they want would make them appreciate you a bit more regardless of how many times you’ve paused to compliment their ass.

Right now trying to increase subject’s friendliness goes something like this:

“Oh my god, your ass is so good. Man, this ass of yours is really great. Nothing like any other ass I’ve tapped. Yep, definitely a good ass. Have I mentioned your ass is good?

Good, now will you please shut up?” Or something. Que friendliness drop that will need to be replenished in a similar manner.

The necessity to go to the quip window numerous times before trying to incentivize certain behaviour doesn’t really help the flow of the game. Plus, earning your right to do so exclusively by talking is extremely unnatural on its own. 

Besides, silent protagonists are trusted by virtually everyone in RPGs, so why not here?

As it is right now, a c-cup is the smallest breast size you can have without having a broad and manly chest. Please make it so the breast slider only affects breasts size and nothing else.

Growth/shrink ray

this would be a very important addition because too often its left out on major adult games and is a fetish too (mainly it involves making fem ejaculate add up, staining cloths making all sorts of mess but too some that is attractive to some. (and having it have physics makes it even more important because it usually fallows a set path (like this blob goes there and a splatter here only thing different is the order)))

Coded preferences for small and large genitalia, ability to make and receive demeaning/praising comments based on genital size, ability to compare your relevant genitals with the test subject and vice versa.

Objet we can create with bay manufactural ap. Option to get more client/subjet to enjoy the one on the bondage ap.
