Yeah, I don't think anal will be next, but soon over all. God's poophole loophole. There are songs about it! XDI definitely see anal coming close to possible, just not at the moment. There's always the possibility of her justifying anal as not being sex or something along those lines given a bit more time. The oracle is definitely helping push her in a good direction, at least good for anyone looking to get with her. It still seems like a less than immediate change, but I could even see a justification later that sex became a religious practice. The expansion part I definitely see in the short term, though how it will expand I cannot even begin to predict. It could be more daring exhibitionism or it could be something totally new, like you said, fingering or oral, possibly in either direction, oral done to her or to the MC. I don't think oral would have any real religious consequences no matter who does it and who gets it nor do I think anything else besides full blown vaginal would, it may just be a matter of adjustment in her, which would take time in universe, but not nearly as much as it would to get her to fall completely.
The time thing, yeah, my current playthrough, which is brand new since the remade intro, is only about a day, maybe a bit more real time, I would have to look at the stats. I'm slacking, I know, I've just been more than a little busy with real life, which has not been kind to me since November 2021. I've had to rely on saves supplied here to see actual new content just to keep myself up to date and no go into discussions on this thread blind. In universe, if I remember any time references correctly, it hasn't even been a year.
The exhibitionism event chain started by the player fingering her in the restroom there, so making a repeatable version of that, or giving us the option to to go her room to do it. Either way.
She goes down on us any time we want, so I assume we can talk her into returning the favor now. The main issue was that before the exhibitionism events, she had never had an orgasm, now that we have broken that barrier, the floodgates have started to burst.
Vaginal will clearly be one of the last things for her.
Sorry to hear it. Hope things improve for you soon.
I am roughly 2.6years in, if I had more free time, I would have passed 3 years already.
