Shin * Anus of Gratitude

Ah, the poor doctor...

Ah, and here is another chapter in the anal man series! I'm always happy to see more.
Also, must be an interesting experience when she sucks on your finger and the first thing you see is memories of sticking your fingers into another man's ass...Yeah, honestly I'm not sure how one would properly react when a girl wants to have sex with you, but she's actually the anus of your patient and you've...stuck your hand in it(her) multiple times in the past...
"A man and an anus can't be together"? No...Probably not, but hey, at least you gave him a goodbye kiss, right?
Except to the doctor, he basically kissed the anal man's anus, so...

Ill never look at my asshole the same way again...

So, ... MC's anus breaks away from his body, takes the form of a cute girl, seeks out the doctor who has come to MC's aid "in that regard", many times in the past, and offers itself (or perhaps that should be herself) to doctor-san in gratitude sand "in that way".

*crickets chirping*

Figuratively speaking, and strictly IMHO, it could all be summed up like this:

Artist's twisted and deluded Imagination: "Omae Wa Mou Shindeiru."
My logical & reasoning thought processes: "NANI?!?!?!"

..............................

Most people know what happens next at that point, so I'll just leave this right here on my way out.

Still a better love story than Twilight...

anus in the title and then it's ecchi? oh well

Almost thought the non-h tag was going to drop for a bit.

Came here to see how Shirizaki's anus long-standing story developed, stayed here for the feels. A proctologist and his main patient's anus: always so close, but all the while destined to be apart.

Real men fuck anuses. DOUBLE MEANING

Bro, is it gay if your homies anus turned into a beautiful woman and ask to lay with you? I'm far too confused at this point
