NTR was planned from the beginning, as was trap, gender bender, futa and all that weird fetish shit. The frequency of which they appear depending on the patreon polls I threw up. The general thought was include a bunch of shit for the variety, but in hindsight, I prob ended up stretching myself a bit thin with it all. Originally it was just gonna be a one-off scene, prob should have stuck with that.
But what can you do? The NTR is too popular with the patreons currently to cut it, so that's not happening, besides, cutting a story arc would just annoy me anyway. As for it seeming out of place, it only seems that way now because I've barely gotten into it, this NTR route is slightly less typical than what you'd usually see, or at least from what I've seen(which isn't a lot I'll admit), it'll take a little while to get to that point though. Unless of course you just generally don't like NTR, in which case it will prob always look out of place to you.
