You find yourself wanting, almost aching to mount her. A fact that she seems well aware of as she turns her back to you and lifts her tail, sending the scent of her heat to your now much more sensitive nose. You end up approaching her almost involuntarily. It's only as you're awkwardly trying to figure out how to push yourself into her that you're fading human consciousness reminds you of what the woman said. That doing this often results in being trapped as a dog forever. You do consider the word "often" and are close to justifying the attempt on the idea that you'll be the rare exception, but there's still a small, nagging worry that you can't seem to put into words. The more you think of it, you can't put anything into words. Your internal thoughts are reduced to emotions rather than words. Trying to remember the actual words for things is like trying to remember a song that you'd heard in childhood but had forgotten long ago.
A whine comes from the female in front of you, distracting your internal thoughts. She turns around to lick you in the face before turning back around and presenting herself once again. This time you only take a couple of tentative steps towards her before backing away awkwardly on quadrupedal legs that were never meant for backward mobility. She whines again as she looks over her shoulder at you. You quickly turn around and scratch at the door. The woman who put you in looks at you through a window next to the door. Rather than letting you out, she simply smiles and shakes her head. You bark at her, but she still stares, her grin taking on a hint of malice. She intends to keep you in here! You scratch helplessly at the door, powerless to free yourself from the situation.
The bitch behind you, rather than the one that locked you in here, howls behind you. You can't help but detect a hint of sorrow in it. You close your eyes and focus. You try and remember where your hands and arms were. You grasp on to your memories of walking upright on two legs, rather than your natural four-legged stance. It takes some doing, but you find a sense of peace in your mind. This helps you recall your hands, your legs and other human features. As you focus on the memory you feel your skin seeming to become loose. You begin to feel your fingers once again. You curl them away from the paws they're trapped in and your arms pull away from the front paws of the suit. It's working! You feel a human torso form beneath your fur and your neck and head pull inward, allowing the mask to fall away. You feel the cool sensation of air hitting your back as the back of the costume opens up. You quickly shake yourself free from it and stand up on your two human legs. You quickly step away from the costume before it consumes you again. The woman behind the door seems disappointed, but slightly impressed.
"I was so close." You hear a tired female voice behind you. Turning around quickly you find yourself face to face with the nude, slender form of an adult human female. Her skin is well-tanned and dark brown hair hangs in a mob around her face, reaching just to the shoulders. She approaches you, taking your face in her hands as her brown eyes peer searchingly into yours.
"I was so close," she says again "all you had to do was mount me and there would me no going back. We could have lived a life of simple pleasures. A life where no thought is complex, where no hard decisions need to be made. We could just simply be. Why wouldn't you want that?" The words come tumbling out of her so quickly that you're left standing there for a moment, unable to answer.
"Seems he didn't see things the way you did." you hear a voice behind you. The woman who'd trapped you here has come back in, holding two clear plastic bags. One bag contains your clothes and the other, presumably, holds the clothes of the other woman. She hands you your bag and walks over to the other woman.
"Can I try again?" the woman asks.
"Perhaps someday, but not today. Take your clothes and go home, dear." With that the former bitch holds her bag close against her chest. She glares at you.
"This isn't over." she says to you in a quietly ominous way. She hurries out the door leaving you alone with the costume shop's clerk.
"I can go home to I assume." you say to her after a long pause.
"Of course." she says.
"Aren't you afraid I'll tell people about this place. Warn them about what you're doing here?"
"Oh I encourage it, actually. Most people will think you're crazy, of course, but those that do believe you always seem to end up coming here despite the warnings. It's strange how often such warning go unheeded." she says. With that she leaves. You give a long look at the dog costume before quickly putting your clothes back on and leaving the zoo. Sleep comes slowly that. night as you go over the bizarre occurrences of the day.
