Xtreme Series

[Sox]

I'm looking for some hentai titles that are a part of the "Xtreme Series." I know Night Shift Nurses is one of them. Does anyone know of any others?

Blood Royale, City of Sin, Maison Plaisir, Stepsister, Slave Market, Sin Sorority, Xtra Credit, and Chains of Lust.

That's about all I could find.

The "Xtreme Series" is a label/brand applied to certain series released by Central Park Media/Anime 18 (and is not necessarily warranted, according to the Anime on DVD/Mania.com reviews). Checking the Anime 18 studio page on Mania.com, I think that the only title Jatz missed is Nurse Me!
