Shi to Ame Wan Nyan - Zen Sekai no Sub ni Totsuzen Kemomimi ga Haeru Ijou Genshou Parallel Hon

A story based on the commercially published work set in a Dom/Sub universe, "Shitsukete Tokashite Abaite Medete".

One morning, Itsumi is thrown into a panic as Sumio had suddenly grown cat ears and a tail.
Meanwhile, a strange phenomenon had also befallen the Sub x Dom couple, Kiyoharu and Kanau, where Kanau grew dog ears and a tail...?

This is a lewd and lovey-dovey story about the two couples, Itsumi x Sumio and Kanau x Kiyoharu!
