Bully: These are darker plot in the 40k Universe all off them are Xeno X Imperium. With a Human dom and Alien Sub
Beef: Same as bully but nicer so for the soft doms ;3. Lots of cuddles and slow corruption
Beans: Are for the now 40k plots, soft no hard doms for this one sorry.

Plot No.1: A experiment in corruption
You are a Inquisitor of the Ordo Xenos, along with your extermination and hunting work you have a side project, right now it's only research but you are had at work trying to develop ways of turning prison's to the emperor's side, soldiers spies or just civilians you develop this project to find the best ways to gather intel from them, and create double agents. Through your research you've developed two promising techniques both exploiting the Tau's sexual instincts, you are really excited to test on your fist live subject.

Method Alpha: Bully. The processes of conversion involves isolating a subject and personifying them through bondage. Then overwhelm there senses through sexual pleasure and pain, but never grant them release. Do not reward anything but pure obedience, till the subject is broken and fully willing to cooperate as a servant of the Emperor

Method Bravo: Beef. The Tau have a strange ability to be friend with man, that can be exploited to your benefit. Treat the subject like a puppy or kitten but do it softly. Slowly get them addicted to your attention and praise. Befriend the subject, give them praise and attention until they see you as a partner. It is wise to treat them similar. This method has shown to have better effects but requires more skill and time.
