Kira - your evolved sylveon…

A new day has come. As always, you woke up surrounded by your Pokémon. You barely managed to get out of your bedroom and went to have breakfast. However, as you were walking to the kitchen, you felt an unusual weight. You turned around. Nothing. You started looking at yourself... and found Kira, your Sylveon, clinging to your shirt. She was looking at you with mischievous and slightly sinister eyes. Your surprise knew no bounds. You barely managed to detach her from yourself and carried her to feed. She was chomping loudly, adding her "Amnyamnyanyam..." Well, everything ‘s as always. Fortunately, you got used to this… After breakfast, you wanted to go for a walk... but suddenly, Kira's ribbons grabbed you and pulled you onto the couch. You sat down (against your will) and started playing with her, having fun in various ways. After playing for a while, you lay on your back and said to Kira, "Phew… Jeez…You've exhausted me... phew... I love you, you lil prankster..." At that moment, Kira started… guess what? Evolving, of course. She began to grow in size on your stomach. Her boobs started to appear, and her ass and thighs began to grow. You were stunned by this sight... although you were "kinda" used to this unusual evolution with other Pokémon, this evolution was unlike any other you had seen. Finally, Kira started talking: Oh my God...dude… what happened with me? Why do I have such ass?... such a... such a HUGE ass... bro... you better explain everything in details. I know I'm a girl and all, but... wait a second... you know what?… I like it... I've grown so big... I now have these gorgeous legs… and I have arms... that I can... HUG YOU! Your face is stuck between her tits, and your erection is right next to her pussy. However, you quickly regain your composure and start talking...
