The artwork here is so good, I don't think they have to worry about 'giving us the goods' too early at this point.
I get that they're afraid if they give us sex with the main 4 right off, we'll all be 'done' and stop supporting them but I can easily see this game taking a different, and well received approach, by turning the 4 prefects into our own personal recruitment force.
Have the next update finally give us sex with all 4, then have them become so enamored with Sal that they willingly start recruiting new girls for him. So the following update would have Daphne bringing Nola on board, with the usual build up for her. Hermoine is tasked with getting Ginny to be ok with more than teasing, Luna devises a plan to get Xandria (the younger one) to be mind controlled and out of the way while Susan... you get the idea. We'd start 'from scratch' with the 4 newcomers while slowly building up towards threesomes with them and the specific girl that 'recruited' them etc.
If they keep on this course of doling out teases and little more, I'm afraid it will backfire on them. Susan and Luna specifically are practically begging for it by the end of this last update, so dragging that out any longer just makes the immersion start to vanish. I feel the audience would love an infusion of new models and new corruption possibilities, with the 4 prefects giving ample chances to expand as well. Just a random musing.
