At the moment, PL has adopted a more frequent but smaller update schedule. I believe this is primarily based on input from his patreons. Due to a change in his employment situation, maybe we'll see bigger updates for awhile? Fact is though, he is essentially working alone on this (he has a translator and an editor to help with the script) and he has some health issues. This adds up to a pretty significant bottleneck in production speed.
As for Maria, yeah... I'm not usually into Mommy-play, but I might make an exception for her.

Unfortunately, I'm a little scared about what happens when she finds out about Katie... She seems pretty open-minded and kinky, but is she THAT open-minded and kinky?
