Based on what the previews have said this update is where Marin gets fucked, Violet gets prepped to get it next time, and Yui moves a bit forward. So my expectation for the next update is for Violet to finally cheat with Yui reaching the point where she'll get fucked in the next update. Seems like a natural progression.
Yar, y'all mind marking the update pics with spoiler tags next time you leak 'em? I purposefully avoid viewing them when Inatari makes the patreon updates so as to be surprised by the artwork for the scenes in the release.
