We're at a legit turning point. Some time before the end of the month the next update is scheduled to release for patreon supporters. In that update we'll see Violet, the mom, move up to the precipice of cheating and possibly getting fucked in the following update, Yui get moved a little bit towards sex, and Marin having sex for the first time. It seems like the most recent update might be starting a domino effect with the most important side woman finally having sex if the progress reports are accurate. Based on the description of future events I wouldn't be surprised if the Marin scene we've been promised and seen WIP samples of happens, then Violet in the following update, and Yui in the one after that.
