For both sexes. This file makes you an anal addict. You need to fill your ass as much as possible. Every time your mind is idle, your thoughts are drawn towards how lovely it would be to fill that ass. The enjoyment you get out of filling it gets bigger and bigger, the bigger the object you can insert. You seem to get a much better satisfaction by having your ass filled than by regular masturbation. Anal stimulation is much more enjoyable, you find. You can trigger yourself into needing it now, or others whom you give the trigger, can trigger you. And while you are filling your ass, you just can't help triggering yourself also. So the more you think about it, the more you also get triggered, and the more compelling it gets! This is identical to the Superfast induction version, it just has a longer induction.
