Blackness. A dull throbbing pain in the back of your head slowly becomes more pronounced. Your eyes begin to open, squinting against a blinding white light above you. Your vision begins to clear, and you find yourself looking at a rotting ceiling, with bright lights blazing right into your eyes. Scrambled fragments of the previous night begin to float to the surface of your mind. You realize with horror that you can't move your limbs, your neck twisting as you panic and sending a searing pain through your body.
"Ow! Watch it, asshole." a scratchy voice hisses from your left, "I can feel that too."
"Wakey wakey." says a familiar voice. A woman's voice. The one from last night, you begin to remember. And that's when you really start to panic, but try as you might, you can't seem to get your limbs to move at all, only managing to twitch and kick with your right arm and leg.
"Ahh! Can't this loser sit still?!" the scratchy voice complains, sounding strangely close to you, practically in your ear.
"What... what's going on?" you manage to gasp. "Why can't I move my body?"
"You mean MY body, you freeloading fuck!" the nasty voice replies.
"Mandy! Such language!" says the other voice, the one you recognize as Dr. Stein. "You do realize that this kind of behavior is exactly why I had to install your new friend in the first place."
The other voice simply blows a raspberry as Dr. Stein steps into view. Your vision is still blurry, but you can tell that she's holding a large mirror.
"The operation was a great success, now why don't you take a good look at yourselves. Or... your self? I'm not sure. You'll figure it out."
The voice beside you grumbles as Dr. Stein holds up the mirror for you to see. Even though your vision is still blurry, you can immediately tell that something is wrong.
The first thing you notice is that the figure in the mirror clearly belongs to a woman, dressed in a provocative and wholly inappropriate nurses uniform with a ridiculously short skirt, the kind sold as sexy Halloween costumes. The fabric is stretched thin over the woman's hips and sizable breasts. But the most alarming sight takes place just above those breasts, where you see not one, but two heads looking back at you. On the left is the head of a young woman with a neat black bob cut and a medical eyepatch over one eye. Her expression is fixed in a sneer of disgust. On the right is your own teenage male head, with its short and scruffy hair, wearing an expression of horror. Dark red surgical scars and stitches mark where the two heads have been attached to the unnaturally pale body.
The head directly to your left breaks the shocked silence, "Wait, seriously? A teenage boy? I have to share my body with a fucking perv?"
"Now Mandy, I'm sure your new friend is no pervert." Dr. Stein interjects.
"He's a fucking teenage boy, they're all pervs! He probably can't wait to get his hands on my tits! I mean MY hands on my tits!" Mandy shrieks.
This is all too much for you. You can't even process what you're seeing, but you notice that you've been clenching and unclenching your right fist. And with some effort, you manage to raise it and give an experimental wave, with your absurd reflection mimicking you exactly.
"Hey, cut it out asshole, this is my body, and I'M in control!" Mandy growls.
The numbness from the anesthetic is beginning to wear off now, and you realize that you're starting to feel the sensations of your new shared body from below the neck. The feeling of your new plump ass against the stiff hospital bed and the unfamiliar weight on your chest.
"Mandy's always been our least co-operative nurse." Dr. Stein says, shaking her head sadly as Mandy sticks out her tongue, "So I came up with a brilliant idea to teach her to get along with others."
"Fuck this, I'll never get along with this perverted asshole." Mandy growls, "I'm not going along with this bullshit."
"Now, Mandy." Dr. Stein says sternly, placing her hands on her hips, "You realize that we've tried everything to get you to be a good nurse, and this is the last straw. If you don't learn to get along with your new friend, we're going to have to call this experiment a failure, and you'll become one of our patients."
This threat causes Mandy to go quiet.
"Okay, you two." Says Dr, Stein, suddenly cheerful, "I'll let you rest for now, then I'll introduce the newbie to your room and your duties as a nurse." She heads towards the door that leads out into the hallway, pausing to dim the lights. "Feel free to talk and get to know each other, after all, you'll be together forever."
And with that, she leaves.
