    Anybody else notice that the doors in the last story looked like they were covered in Dragon scales? Maybe the top in the last story is actually a Dragon in human guise, I mean all through out the manga there were stories about animals turning into humans and the name of the ring had the word Dragon in it.

    I realy love the bride of the red dragon, i would have loved if there was a continuation to the story; but i guess that way it keeps a certain mystery.

    Some are okay but most are a hit and miss. They were either too short or the story was rushed so it was less sexy. The tutor and train ones were had the better plots and flow.

    If I were to rename each chapter in this story, they would be:
    Chapter 1: Cry-baby sensei and scary loser
    Chapter 2: Loser nerd and his shota
    Chapter 3: Two losers fap on a train
    Chapter 4: The thirst is real
    Chapter 5: Desperate loser screws his dog
    Chapter 6: Wasted loser screws his cat
    Chapter 7: Desperate loser cheats on his fiancee and suddenly goes full homo while in China

      "Two losers fap on a train."
      This is the most accurate yet hilarious description I've read in my life.
