What it says on the tin.

The game is incredibly fun, but it would be nice to have the option to pursue a more permanent relationship with an NPC you like, especially a coworker. During one of my playthroughs, the dock worker was a really hot bear. His randomized look just happened to turn out the best looking combos.

It would be nice to flirt with characters and either get them into the rack room or even an apartment?

A bed or couch option would be nice as well, to give a bit more variety to encounters.

Helping subjects achieve certain feats with your equipment. As in, produce some amount of semen, or shoot some distance, or endure some minutes of post-orgasm rubbing. Encourages experimenting with the equipment you've got to maximize whatever measurement they're going for. Could be open-ended improvement.

Can we add a height measure thing in the showers? like a ruler on the wall in feet on one side and meters on the other, just to know how tall we actually are.

when you play the clients are random and not what you are searching for, normally 1 client from the 6 on 2 to 3 times searching for clients is what you are REALLY searching for. we need an option for making our test subjets and in a future case to use them as staff members of the lab.

Currently the camera seems rather limited (behind the character). That can make it difficult/impossible to get the preferred view.

Also it would be better to be able to adjust the view by holding the right mouse button and moving the mouse (compare to Yiffalicious). Makes it easier to change the view with only one hand.

Being able to do multiple actions at the same time, for example kissing

and touching yourself while riding someone would be a great idea. Being
able to automate one action and manually focus on others would be an awesome feature that would give the game a lot more variety.

i suggest make sort of massage table (with a hole) for client to rub them and etc. for this get more money or do experement on subject without noticing behind there back/

So, I'm a huge oral (mostly rimming fanatic) and I think the anus area should be polished up. Right now it's just a pink "dot". Pretty boring. I think you should be able to like, maybe customize the tightness/loosness of it, as well as the color.  So if you want to select a dragon with a green anus, and it's loose, why not? And I don't mean it in a gross way. Some anuses are tighter and some are looser. If you're into rimming, you know it's hot when you see that particular area go with the motions of the tongue 😎
