well, in the 1.1 update i've been working on there are a few more impregnation scenes -- one with khru, but only under fairly specific circumstances (start with a dog dick + bring him to astau + fuck him afterward), and another with a new great beast npc -- but i haven't actually coded up the pregnancy progression there yet. i've actually kind of written myself into a corner with impregnation scenes due to how i've said reproduction works, since there needs to be somebody around to provide the eggs and there are only like, three characters in the game that can do that.
How about something like in the start-up, where we add our points to the specific body part we want, we can choose between the dog dick and an ovipositor dick? Though I don't know how you'll go along that.
actually really early on in development i had plans for something like that -- a monster tf for each of the initial body options, including one that was an ovipositor -- but i had to cut all of them except for the dog dick, since each one is a huge amount of extra work. having that dog dick tf was maybe the single most labor-intensive design decision i made for the entire game, since it meant having to write totally different variants for about half the sex scenes in the game, plus entirely different interaction branches sometimes, plus a bunch of NPC dialog about it. doing that over again would mean writing, like, 100k more content easily. it's kind of unfortunate, since originally i had planned for a bunch more dick-tf options, but ultimately the sheer amount of work required made it pretty infeasible to do it
