Thanks to specnot for the following guide.
Step 1: SKSE
Download the newest version of SKSE (as of this post, it is 1.5.9). Decompress the archive and merge it with your Skyrim folder (usually C:\Program Files (x86)\Steam\steamapps\common\Skyrim). Note: this includes the /data folder included with SKSE-- without it, even if you load SKSE, the keyboard controls will not work.
Step 2: FNIS
Download FNIS 3.0 (assuming you don't already use FNIS and/or don't know how it works). Decompress the "ALWAYS necessary" archive and merge its /data folder to your Skyrim/data folder. For the purposes of Mini Lovers, this is all you need.
Step 3: Mini Lovers
Download Mini Lovers (Mediafire link for ML 0.2.3.7). Decompress it, and merge its /Data folder with your Skyrim/data folder.
If you don't already have an erect-version male body replacer, the ML author suggests Better Males -> Nudes - FavoredSoulMeshes - Erect Version. Just be aware that installing this will make all men have hard-ons when nude.
Step 4: Make the animations work
In Skyrim/data/tools/GenerateFNIS_for_Users, there's a program called "GenerateFNISforUsers.exe". Run this program, and click the big yellow Update FNISBehavior button. Exit the program when finished.
Step 5: Activate the .esp
Use whatever utility you normally use to activate the MiniLovers.esp file (the Skyrim Launcher, NMM, etc). It doesn't seem to matter where it is in the load order so just put it at the bottom.
Step 6: Play Skyrim and try it out!
Launch Skyrim with SKSE. When you load your last save, you should see "Mini Lovers Rape spell added" in the upper left corner of the screen. Assuming you've done everything correctly, you should be all set.
The Mini Lovers rape spell is listed under Destruction magic, and the spell itself has no associated animation. Equip the spell, and stand fairly close to the person you want to use it on-- its range is quite limited-- then activate the spell. When hit, the spell should "grab" that actor and begin the first sex animation.
There are a few keystrokes you need to know to use the animations at this point. They are as follows:
Y: This changes the sex position. As of Mini Lovers 0.2.3.7, there are only five or so that are present. If you go beyond that, you'll just see the actors standing doing nothing. Using shift-Y will go through the positions in reverse order.
G: This switches the giving/getting position of the actors. This is especially helpful if you are playing a girl character and you don't want to peg your target.
H: This changes the "stage" of the animation. There are four stages to each available sex position, so pressing H will move from one to the next. Like with the Y key, pressing shift-H will go through stages in reverse order. When you pass the final stage of the animation, both actors will fall down and you will be free to move around normally again (this is important, because if you don't do this, the other actor will be "stuck" to you when you move around).
Personally, I couldn't get the movement keys to work and the perspective is poor for actually watching the animations (especially if you switch into the "getting" position). Using the Skyrim console, the "tfc" (toggle flying camera) command will let you move the camera around freely to whatever angle you'd like. Even in flying camera mode, all of the keys listed above work. Just remember when you're finished to toggle tfc off again, so you can resume control of your character.
AnimObjects Ero Motion
This link contains the latest version (1.7) of AnimObjects Ero Motion:
How to use:
Download and extract, then inside the new folder, there will be various folders named "Female 1", "Female 2", "Monster", etc. I suggest zipping the folder you wish to use, then putting it in NMM and activating it that way.
You cannot use more than one of these folders at a time. So don't try, you'll just get buggy results.
To activate the animations, simply go ingame, use the spell "FNIS Idle Selection" and select an idle from the "o" list. Now activate the spell "FNIS Player Idles" to play the animation on your character, or "FNIS NPC Idles" to play the animation on targeted NPC.
-Using TFC may cause major camera and clipping issues.
-You may be unable to enter first-person view after using the spell.
As always, keep a backup of your original save, just in case.
Original post (outdated, safe to ignore this):
It contains FNIS animations. Testing them now.
Edit: They work, and they're good.
Pack contains 3 animations, they can't be installed at the same time, as they all replace FNIS idle o-1. I unzipped the pack, then put all three subfolders into their own zip file, which I then loaded into NMM for easy use.
The idles should be cast on the player, not an NPC - had weird results on NPC's. They are cyclic (infinite looping) animations, and while they may be rather basic, the animations are well done. The paizuri one seems to use some sort of BBP, but not what we're used to.
Note that no males are required for this - the idles themselves summon a ghostly man to perform your, uh, actions with.
