Everything About Fiction You Never Wanted to Know.

Deeper is a three-issue pornographic series written and illustrated by Mazjojo from the now defunct Black Monkey group, published around 2013 to 2015.

The story of the first two issues is about boyfriends Daisure Moriyama and Yoshiro Aoyama, two swimmers with a very active sexual life, but who will be separated as Daisuke will leave to study abroad.

Daisuke just thinks he is afraid of being a bottom, which pushes Yoshiro to prove he isn’t. By the end, he still finds it very uncomfortable and Daisuke admits he prefers to be the bottom.
  • Victim Falls For Rapist: Zigzagged. Coach Tetsuo finds Yuuji masturbating in the bathroom. In a moment of passion, he immediately assaults him while confessing his “love” for him. After finishing the act, he realizes he screwed up and apologizes. The subversion, however, comes is that Yuuji returns the affections as they have sex again not because he fell in love for the coach, but because he is using the coach as a substitute for Daisuke. However, Yuuji’s internal thoughts state he feels bad about the whole thing, and despite the coach giving him the love he wished Daisuke gave him, he still wishes he was with Daisuke. Issue 2 suggest they are in a relationship, but Yuuji looks uncomfortable about it.

Yuuji: "“All this time, I've been looking so faraway, when someone who will treat me special, has always been by my side. I wish it was you, Daisuke - san...”
