Not sure what these sub-genres are called - help is appreciated!

So, I've been into hentai for a looooong time now, as far as I can remember. But it was always the same sort, the same category/genre. A few days ago I looked up some weird and random hentai fetishes and sub-genres to see if there was anything that caught my attention. I managed to find some hentai of one genre I enjoyed quite a lot, problem is I don't know what this genre is called...The genre I was wondering about was "mind control" and machinery. As in, a female is completely stuck on a machine where they are endlessly tormented and abused. It sounds weird, but oh well. Heres two examples: Warning: Disturbing, #2. Things like this, I also find quite nice. Although when I try to look up this kind of hentai, I usually don't end up with much. Was wondering if there was a specific name for this type?Thanks in advance guys. Please don't start questioning my fetishes because I am already really insecure as it is. Just posting this is scary for me. via http://bit.ly/1KdTNuj
