Y'know like you can drizzle syrup on the subjects body parts or use a hotdog as a dildo and stuff. Kinda weird I guess.

nipple/clit clamps and/or the ability to pinch

Ever wanted to oil massage a body for foreplay? Spank and squeeze a pair of ass cheeks till you leave a hand shaped red mark behind? Or spread those cheeks open and stretch the asshole with your fingers? Nah? Well, hopefully now you do ;)

Also, foot play could use some time in the sun on Rack 2. A lot more weirdo foot folk (like myself) are finding their awakening nowadays, as evidenced by the Pornhub's most searched suggestions. Maybe not as high up there as "BBC Creams My Wife" or "I Fuck My NOTSister(REAL)", but its pretty popular.

Add the option to cumbrush your subject either with your or their cum

A particularly untapped fetish of mine is having ghostly disembodied hands fondling and molesting some helpless individual. I'm thinking maybe have a little wooden totem of sorts that you can fiddle with and summon ghostly hands to molest your target client (or you).

it could work on the possible mechanics of unwilling, unwanted stimulation (ghost rape anyone?) or have passive arousal and pleasure effects from the gentle caressing and fondling that the hands would do. Maybe have a penile varient where a ghostly dick appears and has its way with the subject while the hands freely molest away. It'd have obvious player controls of course, but I'm thinking maybe you could have a pre-set customizable set of actions that the hands would perform, maybe have the player character use the totem on themselves to set up the fondling animations and such in the background while you work with the phallus, etc, or vice versa.

It would be neat side mechanic to have a negative (depending on your perspective) effect from using it too much that makes it backfire and has the ghosts start molesting and stimulating you instead when you next tried to use it, hampering your ability to do things because of the fun stuff the ghosties are doing to you. Lots of phantom molestation making you cream your pants, with potential for humiliation from the awkward faces and sounds you'd be making from the constant stimulation the naughty ghosties would be doing to you, as well as the embarassment of having jizzed in your pants a few times. Best part? No one else sees them except for the person using the totem and the target of the totem.

I know this may be a bit too complicated to implement, but I figured I'd at least put the idea out there and see if it could be a possibility or not. If not ghosts, then maybe something with similar mechanics as I described above, or some of the above mentioned mechanics under their own things

No gore, but if there's an option to modify a subject's body and you alter it sufficiently (e.g. creating a dickgirl/cuntboi/nullo or altering them completely) they remember the gender they were and react variably (e.g. some are happy with their new body and aroused, some are horrified/upset etc etc)

It'd be pretty cool to see a skinny goth otter guy in some metal band shirt, spiked bracelets, and programmer socks getting jacked-off. Or a chubby tiger lady getting buttfucked in a tube-top and platform heels(Neato!).From sports jerseys to bikinis, a little covering can go a long way. A naked body is sexy, but I think sometimes added clothes, revealing or not, can add another pleasant layer to the whole.

Using special table or where you want(maybe on chair)

specifically desperation to pee, subjects trying to cross their legs / not being able to pee bc of an insertion and begging for it to be removed / acting embarrassed / slowly getting more and more panicked
