[VERY NSFW] Reisen Tentacle Pit

FINALLY done with this.
I didn't wind up doing as many parts of the sequence as planned, as this was supposed to be done mid December and was running way late.
I plan to do a video version with sound too, but after having to re-export all 6 gifs like 7 times each because of render errors, I kinda want to not look at this for like a week first.
