This has gotta be Fluffer's magnum opus lol She goes absolutely all out in this! The video just gets more and more extreme as she adds/switches up dildos and culminates in her fucking this massive blue dildo reverse cowgirl and she very nearly is capable of taking it all in. You can see her tight pussy grab on as much as possible when she pulls herself up off it. She ends the video showing her poor, abused pussy and giving her monster dildo a sweet kiss.
Bravo, Fluffer, Bravo!
