The theme in these two series feels really similar: they are both dark, hedonistic stories about people who gradually become unable to hold back their sexual desire. Thus, if you're more interested in the theme than the plot itself, you might really like the other title. The main difference is that Warau Kyuuketsuki is extremely violent and graphic, while Takato Yamamoto keeps his one-shot pretty subtle and very aesthetic.
