So... there's almost no real setup or anything to anything in this game. The neighbor is suddenly just interested in screwing the protagonist because she saw his dick, and it seems the same will go for everyone else. Honestly, that's not a big deal for me but it is pretty jarring.
I was also trying to look for the scene with Heather, but it's either not in the game yet or there's a really convoluted way trying to get it. I was able to see a new scene with the mother lactating by clicking on the dining table during the weekend, so maybe there's just a specific combination needed for that scene.
