Clothes I'd like to see:

• Latex (Black/White, or customizable)
• Scientist outfit with "ports" (holes for body parts, that being Anus, Vagina, penis, and breast.)
• Strapon (Color customizable via penis color in advanced)
• Gags (for those more fettish people, placed on the head)
• Blindfold (Blinds whoever you choose, maybe have the other subjects do the job for you?)
• Condom (Placed on one of the penis slots, condom inflates rather than the subject)
• Vagina-dom (Works like the condom, but collects fluid from squirting
• Teleporter Sender (Allows you to place your/subjects penis into it. Used like a dildo. If you care enough, you can let them suck them self.)
• Crotchless pants/panties (hole for the crotch, exposing the penis and/or vagina.

To have another player or subject to help you forcing a subject to certain positions, like prying their mouths open or inmobilizing them on the floor 

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.

both genitals or even multiple penises on one person, tentacle dicks

for they can fuck theyselves

will there be group interaction?

Like in Dark Souls.

No reason, would just make the game instantly better xD I'm being serious.
