   Summary

   Nine months had passed since the day Rui had decided to lay his eggs inside Tsukasa, who was now whimpering and crying in pain as he leaned into Rui’s touch, the young human unsure of how long its been since the first contraction had hit him.

   Tsukasa goes into labour nine months after his beautiful mermaid lover ended up breeding and impregnating him with his eggs after going into a rut. Tsukasa is sure that he can lay all the eggs with Rui by his side, so what could possibly go wrong?
