I've never really looked for anal vore porn specifically, other than browsing this place now and then. Might even fit here because it's 3D and western (I guess), but I somewhat randomly found an anal vore video by a dude named Eskoz a while ago that literally ticked almost all the boxes for me, and was like finding a huge golden treasure. Can't really share my excitement about it with my friends or something, so forgive me for doing it here.
While the character models don't really do it for me (the faces anyway), the video itself is spot on for me.
F/F, girl regrets shrinking down (using some smartwatch) when the big girl starts hovering her ass over her and "swallows" her into her asshole before fucking herself with a dildo. Inside, the shrunken girl taps the smartwatch a few more times to beg the big one to let her out, who just giggles at the notification on her smartphone-ish device and keeps going. When the big girl cums, she laughs at the buzzing phone thing again before dozing off into sleep, slapping the phone off the bed and breaking it, leaving the tiny girl trapped helpless in her ass.
It's basically 95% of how I would commission a video, it's insane how much it appeals to me.
Again, sorry for putting it out here, just had to get off my chest how fucking much I love that video.
