All pages are home-safe right now unless otherwise stated, but I don't recommend looking at the REST of these websites unless you're prepared for what you might find.
Pretty Girl Games
Pr0n Girl Games (But no nudity unless stated)
BL (Yaoi) Games (But no nudity unless stated)
And other stuff from Moonphase...
Stuff I found out myself:
NEW BL ANIME (OAV)! By the same company that brought you Sensitive Pornograph, this is based on a manga by Yamada Yugi-sensei called 'Saigo no DOOR wo Shimero! Act. 1' ("Close The Final Door! Act. 1"). I have very little idea what it's about, but if it's as good as SP, it'll be hysterically funny. Actually, the short summary makes it sound stupid, overblown and cute. AWESOME. Unlike SP, however, the seiyuu are not in disguise. They are Suzumura Ken'ichi-san, Morikawa Toshiyuki-san, Toochika Kouichi-san and Takimoto Fujiko-san. Released 23rd March.
