Eroman - Kami To Pen To Sex To!!
This is seriously so good! Also i love the author. So at first i didnt read the talks cause: 1- I was tired 2- My english skills were horrible.(didnt understood most of it) At that time i totally thought the first chapter was about the artist and his friend (that was a special being) that needed to be drawed up by author-san.( Cause he looked totally badly drawn). This made sense to me since i thought the artist was drawing his anus on the first chapter. Now i took my time to read it seriously and realised that i like the story not only the sex scenes. Man, the trap really annoyed me this time, though i ship him with the editor-san (ussan) cause they are hardcore. I'll always remember this manga by the scene with the Pen on first chapter and the seme's sweet potato Dick.
