Man, the tail bursting through the ass is such a cool way for it to grow in!

But what about sex after transformation and food intake?
I can' stand for this poor logic in my porn!

They lose their human skin. They still have actual assholes after turning into dragons. Their tails just burst out of their human sphincters.

This one got commissioned by a dude named "Norz" on furaffinity, I believe. The ass-tail (and dicks ripping out of, and replacing, vaginas) is VERY much their thing. They've got like a dozen pretty deece fapfics all depicting the same general process on their userpage, and they're all written in the style used in the comic; check them out if you liked that maybe?

>Goodbye pussy! Hello cock
That's the only detail that spoils it all :/
It would have been so much better (and more practical even from sexual point) to have both
