What is the best toy for anal sex?

Been looking for a toy that simulates rimming, or at least the movement of a tongue inside, but haven’t found much – either toys or reviews. These 3 seem to be the most promising, which ones do you recommend? (Or any others I missed)

[Bums and Roses Rimming Rose](PS: I know about the B-vibe butt plug, but I’m looking for something more external. Thanks in advance for your help!
