Im sure at some point more would be implemented but currently the game has minimal foot/paw play mechanics/animations, posting this in hopes that more will be added in the future.

I don't see this a lot and this fetish is kind of rare but some of the community who know about cardiophilia and have it, would like to see this implemented into the game most definitely.

Macro/Micro Mini game or something

Or the practice of eating food off of a naked body. 

having a snake as a member option would be pretty fun to make it simple just have it operate like the other members just look like a snake. It could open the way for some other kinky stuff.

the general idea of null bulge, rubbing that bulge without any release, begging for it. maybe with a lock symbol or infinity.

Being able to tickle feet is great but what about other areas like pits, sides, other generally ticklish areas.
