Using saline to increase size of genitals and other body parts.

You have a subject sitting in a suspended box, and their junk is peeking out through a hole in the bottom. Do whatever you want to them, and based on what you see happen to just this little bit, make guesses about their: species, kinks, sexual stats, etc. The more accurate you are, the better the reward!

and the legs/butt proportions are strange, the butts always look flat, and the legs look too skinny

Give the player manual control of the height of the rack chairs/tables/stocks instead of relaying on the IK.

A tank full of Aphrodisiac gas connected to a mask that fits the subjects. The gas constantly delivers the gas into the subject, making them extra horny

And the dialogue.

IRL, dogs have a bone inside their dicks.

A bendy penis thus looks REALLY painful to those who like anatomical accuracy.

Basically for people who don't like Diapers but still wear something close to it without being a baby but more tribal

Maybe there is a place inside or outside of Rack Laboratories that you like and would want to take a picture of, or there is a hot coworker or test subject or taking a picture that you want (since you are a stalker, either that or you like having specific character references or you like looking at something or someone). First-person POV will be really helpful in this kind of thing, especially when you are screwing someone and want to take a picture of their "looking pleasured" face or "O" face just before or when they climax, or when they have sultry bedroom eyes when you go in and snapping a picture of them before any interaction.

If you are in a relationship with someone, if they are walking with you around somewhere or they are on a rack in Rack Laboratories (as a date), you could take a picture of them. If Fek decides to go ahead with this kind of thing, you could take a photo when you go on a date, eat out somewhere, go to a strip club or a sex toy store together, or have sex on a bed in your house/apartment or office.

I do not think that making a camera mechanism would be too difficult or long to make, but Fek would have to figure out whether or not this would be beneficial for the gameplay.

You can take pictures of yourself during customization, or when you're just standing somewhere or along with someone. Plus people can take pictures of any visual glitches in the game and show them to Fek so he can take a look at it before another update comes around. Also you can ask someone to smile for the camera before you take a photo of them, including coworkers, test subjects, or other NPCs.

Or would 3rd-person screenshots in the game would be a better idea?
