Yeah, it was just his guts.
Since J said to Mako that "You shouldn't of had eaten my lower body first, I dont feel as much pleasure here"
You should notice the part when Mako is inserting his hand between J skin and insides. (You know like tearing the skin of a raw chicken) When the were talking after he put J in the bed... He is making a space for his dick.
I have just one question that I have for chapter 1 of this manga. How did he fuck the upper half of his body? Im so confused on how that would work, like would he just stick his dick anywhere and hope for the best or what? Idk why I am so intrigued by that lmao!!
