Madonna ~Kanjuku Body Collection~

Mature women with enormous breasts fill every hallway of this apartment, trailing pheromones and living by the motto "do as you please." The hero can barely function anymore, so he decides enough is enough and plans to move out to finally live like a normal student. Naturally, that's the exact day a new building manager shows up.

The story runs as a kinetic novel, so there's no branching to chase and no choices to second-guess. You read through the escalating temptation as the protagonist's resolve to leave keeps colliding with the women around him, incest and infidelity included, before the situation with the new manager takes over. It's a straight sit-back-and-watch visual novel, played beat to beat rather than steered.
