I emphasize teasing because I define teasing as everything beside real sex like your stage 1/2/3 whatever Sophia do besides real sex is for teasing audience purpose..And the developer end the update whenever he add those part whether it's stage 1/2/3...and for these stages he waste so many renders on dialogue, creating mood and in the scene from different angles with options whether to stop or to keep getting filthy..that ends up to nothing....it end up Sophia saying no no no in the end.....So I am just saying that if he has not planned to include the real sex, until then he can focus on the main story part rather wasting render on teasing and he can cover other parts of the story too, like if he is not willing to show Sophia/Ellie full sex then he could have covered morning and noon story in the single update..but again as I said he will waste his time on developing renders for stage 1/2/3 level of sex part for half of the time. Offcourse I mean add those stages of sex but he don't need to add it in a long way as he did kept doing it ..he can just show the stage where did Sophia has reached now with few sexual scenes and move on with the story.First of all, I don't understand why you emphasize 'teasing'.
(I literally have trouble interpreting this, and this is not to fault you.)
What I can say is that regarding 'sex' in steps 1 2 3 4, sex does not only refer to Sophia. (Others too, of course)
As mentioned earlier, there are of course routes such as Sophia/Ellie and Sophia/Dylan, but it is very likely that Sophia's, Ellie's, and Dylan's are separated.
Like Andre/Jennifer sex.
So, even if the step changes, it is still too early to be sure that this developer will change the way he has done it so far.
I did not place Ellie's sex and Sophia's sex on the same line, and as I mentioned Ellie's sex and Sophia's lesbian (no sex, but sexual), there is a possibility that they are mixed somewhere between stages 3 and 4.
And I think there is a possibility that it will continue that way for some time to come.
I think 'this developer needs to condense the story', as you want(and me), but I've yet to see anything to suggest that the '2 years per PD' development period has changed or will change.
