Her Cycle
"What do you mean by acting weird? Are you going to have trouble controlling your forms?" I asked, thinking about the first time we had spared, and she had become a red werewolf that stood on two legs. There was also the last time we had been together when Penny had taken a more wolf-like form and let me ride her.
"Huh? You don't know what this is?" Daphne asked as she came over and patted Penny's head, making her face go red and then press into my chest.
I frowned and thought about it, but I really didn't know much about Dogfolk. Unlike Catfolk, they are not a common race, and they were not really suited to Catfolk, so other than with Goldenia... Wait! Even though I knew she was Dogfolk, I had always considered her form to be more fox-like, but she did get horny spurts... but was that what this was? Was this Penny going in heat?
