There are both speed up and skip entirely options. Make sure to check them at the bottom of the screen; speed up is my fave for the longer scenes (looking at you Android) because it conveniently stops at player choices.
Oh, and yeah, while this is at its core a sex game, story isn't a bad thing, especially when, for this character especially, an explanation was needed. Kali for example started out weird with the whole "what excuse can we have to unlock a sex act", but slows down as it becomes more about her and her relationship to you, then the cool overarching lore/story thing with her dad. Runey sprinkled in plenty of sex too to keep it the way you in particular prefer.
