Jealous

There seemed to be a feeling of jealousy he was feeling right now. Katsuki then sniffed like a cat. He snorted and searched for a scent from Shouki's body.

 "Katsuki, why are you here? I'm not in a rut, so I'm not releasing my sexual pheromones." Shouki joked while holding the tail that appeared suddenly on Katsuki's body.

 Katsuki reflexively showed his fangs, as a natural instinct Werewolf who felt danger he immediately showed his fangs and claws. Even though Shouki was just gently squeezing Katsuki's tail.

 "Shhhh grrrr." Katsuki growled softly, he was annoyed because Shouki suddenly squeezed his tail, it made Katsuki's sex hormones rise. "D-don't do that, it hurts."

 Katsuki's nipples hardened and popped out from behind Katsuki's case, immediately Shouki, who was furious with Katsuki, pinched the nipple tightly. Katsuki groaned and immediately went limp in Shouki's arms.
