Since some people seem to have gotten that impression, I’d like to answer that:
No, don’t worry. I had planned to do Futashy as a bonus from the very beginning, so I thought I’ll just start the bonus series off with her. And since I don’t know any other futa characters and I’m no fan of stallions, the rest will be purely female, as usual.
I’m still open for creative and interesting suggestions, by the way!
