I keep coming back to this one animation, not because it's good exactly, but because the robot design is so stupid it circles back to being fascinating. It's got these mechanical tentacles, right, and they move with this jerky stop motion quality that reminds me of old Flash animations from Newgrounds. The blue haired girl just kind of... accepts her fate. No struggle, no setup. One frame she's there, next frame there's a robot appendage working its way into places that would require some serious prep work in real life.
The sound design is what gets me. There's this wet squelching that loops every three seconds, and it doesn't sync up with anything happening on screen. I had the tab open while scrolling Twitter and forgot about it, then heard what sounded like someone stirring mac and cheese coming from my speakers. My neighbor definitely heard it through the wall. The robot makes no noise at all, which is somehow worse. Silent metal tentacles doing unspeakable things while the girl's voice actress delivers lines like she's reading a grocery list.
The anal scene comes out of nowhere. One moment it's standard hentai fare, the next this robot has decided to multitask with zero warning. No warmup, no lube, just cold mechanical efficiency. The cumshot at the end sprays in this perfect geometric pattern that defies physics. Like a sprinkler system designed by someone who's only seen sex through a kaleidoscope. I've watched it four times now trying to figure out if the animator was being ironic or if this is genuinely someone's magnum opus. The seed lands on her face and just sits there, glistening wrong. You'll know what I mean when you see it.
