Alright, somewhat went over the thread, but zoned out on some of the... less interesting stuff to me...
Anyhow as for things I'd like to see:
Being able to "win over" characters that would usually be locked behind the "pure" or "corrupted" states. Basically along the lines of the request for more middle ground options. Not "purifying" or "corrupting" them but rather being able to do stuff with them that usually would require doing either of that but without changing their disposition too much. I don't know how to describe it better.....
On to easier things:
Cum inflations. Because filling your partner(s) with so much cum they look pregnant before it even had the time to fertilize anything is sexy, I think.
MASSIVE cum inflations. Because putting so absurdly much cum into them that they become a giant belly just pushing you down into the bed is also very sexy, in my opinion.
Mixed cocks. Have a horse penis with a dogs knot. Or a tentacle penis with a dog cock + knot as the tip.
Alternatively:
A slime cock that you can turn into whatever type of penis you'd like on the fly.
Multiple cocks. So I can stuff both holes at once. Or different holes on different people. Or all the holes. And fill them all to the brim.
FIT girls/characters. Like, I like the soft girls, too, but there's also something about the way slightly defined muscles move under smooth skin..
Maybe some kind of Gallery mode where you can replay encounters and one time events with other specifics/choices without having to make extra savegames and change everything. "Okay that was nice, but what if I had fucked her ass with a horsepenis instead? What If I had 5 meter long tentacle penises? What if I lost the fight?" You know.. just so you can see more of what the writers labored to make easier.
Maybe I'll think of other things later...
