I really do love this series, but I can't help but feel that every chapter essentially retcons the last. Chapter 4 sees them fused together and changing a woman into a futa with their breast milk, then chapter five has them split into two entities that share sensations, and then this chapter has them as two separate individuals again, but permanently as futas. Aside from the end of chapter 3 and the beginning of this one, I feel you could stitch the comic together and eliminate the whole part where they fused entirely.
