I get it's a porn game and ppl like this kind of stuff, but these characters are just bigger and even bigger tits like you maxed out there tits. I look at the logs you didn't even spell pregnant right or fertility right. 💀💀💀💀💀💀
The first one is a mortal combat reference.
The second one is perhaps best explained with this youtube video
And obviously I didn't max out the tits... There is also small chunks of breast expansion, so if they were maxed out to start with then they couldn't expand.
You'd get a lot more insight by actually trying it, rather than making snap judgements based on what's visible without actually touching on the content. Something about judging a book by its cover and all that.
You might be pleasantly surprised to find there's more substance than just what you're focusing on. In my experience, there are more than a few games with a theme or focus that's unmistakably on the mature side, but that are relatively deep and well-written. Then again, I'm just a random commenter on the internet; my word's not worth much, so you may as well find out firsthand instead, right?
