Yuuuuuuuuup.
This whole series of bunk updates with lots of flashbacks to other people fucking has been a bit underwhelming for those of us not into watching other people have sex: I had to smile a bit at the Patreon plugs for scenes I had absolutely no interest in. Cis certainly fell down several rungs on my list with this one.
Ah well, there's always Fatima and bullying Cole.
It actually makes total sense... these bunk conversations have the purpose to deepen the connection with the main cast (which are also the five love interests), so it's mostly background stories and past events, when Jimmi was totally innocent and naive. What did you expect, that they were having an orgy in the bunk beds?
In addition, in the case of Cis, there's the whole incest stuff that will anyway take some time due to how Jimmi's brain is wired (which is something that actually I appreciate of this whole first phase: the main character doesn't start from a blank slate, so some things are easier to obtain -straight sex- and others -like gay or incest- need a bit more time).
I wouldn't have expected any actual sex scene with Cis, as I didn't expect it in the Sam update (the Cole update is a wholly different beast)
In any case, I don't see any problem if a bunch of sex scenes do not involve the main character, for once. It's still sex...
