Why, if you are willing to serve me I won't say now. Generally however, it's more so of a dominant thing in the general term however. Some folks may want to willingly serve straightforward and I am generally okay with that so long as they don't really do anything that can kill the mood, others want to act 'unwilling' or actually and I mean truly undergo some form of hypnotic conditioning. In the end, all forms require consent and without it there would really be no mutual joy in the act. TLDR; it more so extends from the fact that one of my primary kinks is BDSM and I have a thing for master/slave or owner/pet things
