There’s a site for every fetish, and if your fetish happens to be watching people swallow live goldfish, then check out goldfishswallowing.com. From their site intro:
Our website offers hundreds of videos of beautiful girls and tight men swallowing whole, live goldfish, tetras, bettas, sharks, and other aquatic creatures. Other small items, like diamond rings, wedding bands, sockets, and pretty much anything else that can fit down a throat, can also be seen within our pages. With the largest swallowing archive anywhere on the Internet, you will definitely find what you’re looking for, and we are certain you’re going to love it!
They offer some more info in their FAQ:
Their sample videos all are safe for work (unless, maybe, you work in an aquarium). Which is to say, that although the site may superficially resemble a porn site, that doesn’t seem to be the case — i.e. no nudity. It’s just good-old, wholesome fish swallowing.
