Jenny the Pokemon (Archive Link)
This author often writes their stories from commissions, which is the case here as well. There are two chapters, where the first is split into two parts. It’s about officer Jenny from Pokémon and how her new position in a new police department involves some intriguing entrance ceremony, where she has to dress up as her Pokémon and act like it for some time. Turns out she enjoys that more than anticipated, and she goes on to her own adventures with the costume she has been given. The entire work involves a lot of pet play, buy for me, especially the first chapter, has some very interesting and fun elements.
It turns out, that one of the Pokémon the MC has, is a Zoroark, which has the ability to shape-shift. What ensues is her dressing up as a different Pokémon and Zoroark transforming into her and taking her place. For me, this is a phenomenal concept and I which the author went much further with it. Sadly, the second chapter doesn’t include much of that scenario, but all in all, it’s a wonderful read and I hope there are more stories that play around with this concept of having someone or something else take your place (consent or not).
