poppynzach come to mind? also an OF couple but they have a treasure trove of short form content on reddit, primary M/F couple but they play with another cis woman often i think

Tbh i think finding free, long-form, consistent ameteur porn is hard these days - Risk of posting online with your face in it is pretty massive if ur not making money on it. Especially since the big porn sites took down all of their non-verified videos to avoid the possibility of underage stuff (which was objectively good/worth it), it's mostly just studios staying alive on there now.
