Cream Lemon

A collection of short stories, ranging from soap opera (the Ami series) to fantasy (Rall series) to horror (Cream Lemon Dark) to parody (Pop Chaser). It does deal with a lot of heavy perversions ranging from S&M, male rape (by a bunch of females, that is), bondage, torture, yuri (lesbian love) and incest.
