The housewife gets REALLY pregnant (overdue chubby woman with twins) in Chapter 2, so that's fairly big. I don't want to spoil Chapter 3, but Megan is in Chapter 3 as a creamerie and gets really really pregnant. The other creameries get larger in Chapter 3 too.
I'm looking forward to that! I'm almost done with Chapter 2 and enjoyed how massive her breasts got in the second daydream and, with 5 chapters total, I'm hoping our housewife goes through a second, much larger pregnancy.
I'm working on a new project now, and will finish it either later this month or in January. Either Chapter 3 or the Neon Dreams update will be next, I'll probably let the Patrons decide.
