You look down at the anthro gryphon costume you chose. Suddenly realizing you accidentally picked the female version instead of the male one like you meant. You try to find a way to reopen the wall and put it back to no avail. Sighing in defeat you walk over to the mirror and slip on the costume.
Starting with the legs you step inside and find the lion paws too narrow for your feet forcing you to stand on your toes in the costume, pulling the furry legs up your thighs you find it slightly easier to slip on, almost like the costume is shrinking your legs to fit inside it. Once you reach the plump butt you feel a jolt at the back of your spine. Turning around you realize it’s the costume’s lion tail. You experiment a bit and find you can flick it side to side, touching it you feel a sensation run up your spine like you just touched a part of you, that leads you to feel a bit concerned about the next step, you gulp a bit looking down at your manhood pressed against the inner walls of the costume and then take a deep breath and pull up.
You feel a pressure in your crotch like you got kicked in the nuts, then it goes way. You snake a hand to your groin and find a pink slit waiting there covered in tan fur, you were officially now a woman.
You stare at your reflection in the mirror for a bit, getting used to the sense of having nothing between your legs and a tail above your butt. You spread your legs a bit to try and find some trace of your manhood, to no avail you were female inside now.
Resolutely you pull up the rest of the way of the costume, it sticks to your belly melting away your fat and giving you a nice toned midriff with the hint of a six pack poking through your fur.
You slip your hands into the arm holes and shrug it up onto your hand’s somehow fitting into the four fingered talons at the end. Your chest feels heavy as C cup breasts fuse to your skin, hidden by the white feathers.
You look down at the mask and slip it on over your head. Your mouth and nose grow into the beak, your eyes moving towards the eye holes and expanding to fit them.
Finally you reach around your back and pull up on the zipper. Your spine curves back to balance out the wings and the wings fuse to your central nervous system becoming a part of you. You and the costume were now one. You were now a anthro gryphon woman with wide hips, C cup breasts, muscular arms and thighs, and a toned six pack.
Your face was a mix of human and bird like, sort of like a cartoon of a female eagle rather than a full on bird face. You could move your beak and express yourself almost like they were lips, allowing you to smile and frown a bit. Having a beak, wings, breasts would take some getting used to, but eventually you would adjust.
You stayed in the room for a bit examining your body from every angle (and of course groping your new breasts). Getting used to walking with digitigrade legs, only having four fingers, and learning to flap your wings.
Eventually you decided to test out your new wings and went to the door to exit the nexus and enter a new world…
