Before I gush about how awesome the animations are, I'll get the disclaimers out of the way. First, they are technically sex animations, so you would still need Sexlab and everything it requires, and once the prey is consumed, they just burst out of the pred's belly as if nothing ever happened once the animation ends. Second, all of the animations are between either a dragon or mammoth as pred, and human prey, there aren't any human pred (or creature prey) animations yet. Lastly, I didn't have any involvement in the creation of anything listed here, this is just a compilation of pertinent information. That's all that I can think of at the moment, now for the good stuff.
Like I said before, the mod adds seven(and the author has plans to add more)very well made vore animations, specifically: four oral vore animations, one anal vore, 1 unbirth, and one that is both AV and UB at the same time(two prey). Six of the seven use a dragon as pred, with the remaining one using a mammoth as pred. All of the animations are sexual in nature except for the mammoth and one of the dragon OV animations (although the dragon will still sport an erection because it is still technically a sex animation). The OV and AV animations were intended to be used by male dragons only, though, so you will have to mess around in the sexlab mcm menu to make it so female dragons can use them (Which is probably a downside, but I'm too lazy to move it up with the others now).
VIDEOS
I should probably also mention that the author of the mod also has a little extra mod you can download which changes the animation of the dragons bite and throw killmove into one where they actually swallow whoever they grabbed. I got it to work fine, although I had some pretty significant clipping during the swallowing that you may or may not experience, and of course the ragdoll will just drop out of the dragons belly when the prey actually dies.
Here's a video of the killmove in action:
RELEVANT LINKS (You will need a Loverslab account to see the pretty pictures and download things, it only takes a few minutes to make one)
Actual download page for the stuff(click the big green download button towards the top):Horny Dragons of Skyrim v0.86 / Drag Anim v0.93
*NOTE* : If you just want the vore stuff, you only need to download "SLAL_HornyDragons_Animations_V0_93.7z" (and "vore_killmove_test.7z" if you want to try that out). I reccomend picking up "HornyDragonsofSkyrimV086.7z" as well, as it lets you choose in the ingame mcm menu what style of dix that dragons have per race. You can even make it so they don't get erections during the sex animations, which may be necessary because I haven't seen any other way to prevent female dragons from getting erections when they are unbirthing people (not that there's anything wrong with that.) In addition to all of that, and it may or may not be required to make the animation pack work, I haven't tried running the animations without it. I would very much appreciate it if someone could test this for me.
