I'm happy to read your thoughts!
Currently there is a small ammount of visual progression in the lewd screen, the hole gets gaped and you can get creampied until you're full. Also, if you've met the mimic during the wave intervals, let it have it's way with you. You'll get the iron plug, that also has visuals in the lewd info screen.
I'm going to add chastity cages and all of that good stuff at some point, it's definitely gonna happen!
