You shake your head again. Your rubbery mane flowing around you. You've been at this for hours now. Who knows what will happen if you spend too much time mulling this over? You might get stuck like this forever just by casting the spell too late. Even if there isn't a technical deadline for your body those thoughts of just surrendering to the lighthearted pull to simply love your new body are getting more frequent.
The spell, thankfully, doesn't require special herbs or reagents you have to go looking for. You stand up and turn your body away from the mirror and concentrate. Your hands make the required gestures and thankfully your new mouth and tongue can make the arcane chants required to effect the spell. You repeat the gestures and the chants over and over, trying not to lose heart. Just as things start feeling dim, you feel a numbness come over your body. The rubbery body you find yourself in begins to feel slightly loose. The odd feeling of being entirely made of...whatever this thing is...begins to give way to the pumping of a heart. You begin breathing deeply and can tell that, unlike before, breathing is necessary rather than simply a habit you hadn't gotten over. You concentrate harder, driving away the silly thoughts and jokes that you're certain are a product of the suit's desperate need to keep you...to be you.
You realize as you feel the rubber mask beginning to pull away from your face, that you're finally winning. The second skin is beginning to pull away down your neck, over your shoulders and down your back. The rubbery hands no longer belong to you. You have to remind yourself to stay focused when the feeling travels past your gut and over your pelvis, returning the feeling of having genitalia. As the suit pulls away from your legs and down to your toes you smile. The flap that covered the suit's zipper has returned and you quickly pull it down, pushing the mask away from your face and off your shoulders. You're free.
You shake your head, loving the feeling of the the yellowish brown fur of your natural mane flow around you slightly. You turn back to the mirror and smile as you run your paw-like hands over your furry chest. You even give your maleness a slight rub, though it doesn't emerge from it's sheath. You chuff happily. Glad to be a natural anthropomorphic...lion...again?
The though seems slightly strange for a moment. Almost as though this body isn't quite right. But it's a silly thought that you immediately dismiss. The very idea that you were a human must be the suit's last attempt to trick you. After all, you think to yourself as you stretch a body much larger and more powerful than the average human even if I was a puny human once, this body is a vast improvement.
You feel a strange warmth come over you as you sit back down. You reflect on how it's a shame there aren't any anthropomorphic lionesses around. You look at the books on magic you were just reading.
"Yet," you say aloud with a smile. The thought is very...intriguing.
