If you really want it, I can send it to you directly, or you can find it by googling "spider blowjob creepy" or something like that. (I specifically say "googling" because I was unsuccessful in finding it on DDG. I didn't try other search engines.)
I don't know what the gif's origin is, but it was semi frequently posted on Reddit. To shamefully continue referencing Reddit, this probably wouldn't be your proudest fap. (I originally said "I can assure you" but then again ... You did request the gif and I don't know you.)
edit: Improved my originally very cavalier approach to grammar. Did not change the message of the post.
::: spoiler spoiler edit 2: Apparently the appeal of this was more widespread than I thought. I didn't want to post it publicly because I don't know how all of the clients handle image previews and didn't want to force the image on anyone; also I couldn't validate the quality or security of the website I found when searching it, but if you really want to see a spider blowing a guy, here it is. :::
Not sure "neat" is the word I'd use. Its existence doesn't upset me, but I wouldn't mind if it didn't exist.
Neat in the macabre sense. Because while it's disturbing for sure, it's interesting someone put that much effort into production effort of such a thing.
