Sensei ga Okiniiri
Complete | nanase kai | 2000 released
What I expected from the cover: Threesome! What I got: no threesomes :( .. RAPE D: ... Bloody - maybe I do like my rapist after all! :( .. Apparently it's from a collection of one-shots - but this is the only one translated.. I honestly doubt the rest of the volume would be that good based on what I just had to read.
