The long wait is shown in the story line, because it is deep and can go on for a while - I reckon. The scenes are well thought out and the renders are superb (except for the cum part). The shortness is something to be expected with only a few weeks development time, but he gives us enough to ask for more without doing a rage quit each time.
@Jeff Steel I have a question: my daughter advanced with Elena back in the day (When Elena saw them kissing for the first time) - but somehow that has all been forgotten? She played with her in the shower and on the bed creating a connection (and sharing route for a threesome). The current update has a shower scene that has some of it, but it doesn't feel connected whatsoever. In fact; since that day there hasn't been a single reference or scene that adds up to to it. Did you script guys forgot that it happened? I would be so awesome if Elena would wake up the daughter with a kiss and D would make nothing out of it, because she already did so much more with her to begin with. These small things break immersion for me.
