It was supposed to be a simple hunt for the chaos emeralds for Tail’s experiment. 

The young fox wanted them to see if he could make a way for anyone who wasn’t Sonic to create their own super forms. He even considered the idea of being able to use chaos power without the emeralds in hand at all. 

With that, everyone went around looking for the emeralds. Using a spare locator that he had created for the hunt, Amy came upon a part of Mobius that she hadn’t seen before. The deep woods seemed to stretch far and deep. With her hammer ready, she wasn’t worried about seeing and fighting any nasty monsters that would get in her way. But the more she walked around, the more she noticed something about the dark forest. 

She never came across anything.

No bugs. No birds. The few wild flowers that she did see were these beautiful dark roses that caught her eyes. She couldn’t help herself as she’d taken a couple of them for herself, hoping to incorporate them into some dresses she has back home. The further she went down, Amy also noticed that the clearing she walked down seemed to grow wider. She noticed more of the same black rose bushes lining the way and it was here she readied her trusty hammer. 

	“This place is way too creepy…” she said to herself. 

She couldn’t knock off the feeling that she was being watched. She’d faced all sorts of monsters and egg robots in her time but this place was just… Off. Off like she could tell it wasn’t just a person looking at her. The opening path felt too perfect to her simply wandering around. Like the forest was driving her to go deeper in. 

After some time, Amy finally came across the first building she’s seen since entering this place. 

It was a large ancient looking castle. Purple ladened bricks, a bunch of spires that looked imposing and a large series of stairs  leading up to the open double doors. 

Hugging her hammer nice and right, Amy walked up the stairs. Stepping on the first stone caused her fur to raise on end and she knew that something wasn’t right. She took a deep breath and walked in, knowing that the herald was likely inside the decrepit castle. As she walked through the front door, she was surprised to see that the inside did indeed have light. Mostly from holes in the walls and ceilings. It smelled somewhat wet, like it had rained only a few hours ago. As she walked through, the smell of rain grew more intense, along with the odd fragrance that the black roses gave off. It wasn't unpleasant at all, in fact it made her somewhat more comfortable. Almost reassuring.

As Amy walked through, observing the layout of the castle was once something beautiful. Any furniture that caught her eye had long since been ruined from exposure to the outside. She wondered just what kind of place this was in its heyday. The flooring was purple. Fallen chandelures now on the ground or hanging loose on the ceiling. Many faded candelabras decorating various rooms and hallways. 

The deeper she went down, the more she wondered if anyone was really here. She wouldn’t admit it but it felt as if someone was guiding her forward. She pushed the thought away and simply focused on trying to find the emerald and get out of here as soon as possible. 

At the end of a long hallway, Amy traveled to what she assumed to be a way to the backyard. Her guess turned out to be right and the pink hedgehog came across a large graveyard. Headstones decorated the land with many paths and walkways that seemed to disappear into the forest surrounding the castle. As she walked down the stone walkway, she looked back at the castle. The still present sun seemed to make it seem so much more intimidating as it peeked from behind it. 

	“Come on, quit being scared!” She shook her head to clear her mind. She took a deep breath and kept going forward, Hammer on her shoulder and ready to swing down. “Find the emerald, grab it and get out! The sooner this is done, the better!”

As if listening to her demands, fate decided to listen to her request. Amy soon came across a large coffin sitting in a large open space, surrounded by the many headstones for decoration. Sitting on top of it is a large blue chaos emerald sitting perfectly on top of it. She beamed and skipped over to the coffin and eagerly snatched the Emerald without a second thought.

	“Oh thank goodness I found you! I don’t need to be around this creepy place anymore! I can just leave and never come back here!”

If only Amy looked back at the coffin and she could have saved herself.

The coffin laid the emerald as bait. 

It silently sat up, opening its door up and from the darkness within, shadowy arms shot out to grab the hedgehog. The air whooshing behind her caught her attention and before she knew what was going on, Amy let out a dark scream as the hands grabbed her body, causing her to drop her hammer in surprise. Before she could make any more sound, the limbs pulled her into their coffin home, embracing her in the darkness as the doors shut tight with a loud slam. The casket tumbled and shook, showing Amy’s struggles, but just as soon as the attack happened, the coffin went still. 

The surrounding headstones being the only audience to what just happened, the entire scenery seemed to go deaf. The casket soon fell back onto the ground. In the same spot that it was in before the attack. As if it had never moved.

Moments later, it opened up.

From within the darkness, out stepped a newly transformed Amy Rose.

Instead of her normal pink skirt and dress, Amy was now wearing a much more gothic outfit. Long, tattered and flowing, the white dress almost looked like it had seen better days but the withered look complimented the ghostly style of the clothes. As did the subtle spider web pattern on her purple top that faded into the dress below. Her new clothing flowed with a grace as beautiful as her own as she levitated out of the darkness.

Amy’s attire wasn’t just the dress. She also has dark purple shoes, and the many roses that she’d picked up had taken their spots at her new purple cuffs and one sitting on her slightly paled pink fur. Right next to her ear. There was now dark eyeshadow on her closed eyes. Black lipstick and dark blush makeup now covered her beautiful face, and it all seemed so eerily natural. So natural, that it almost felt like as if she had been born with it.

Amy’s lips curled into a smile, showing off new sharpened teeth. She opened her eyes to reveal a pair of dark red piercing eyes. Any trace of innocence and worry that was once inside them seemed to be were long gone. Filled with both a dark lust and a predatory hunger. Both of which were so intertwined, that they were one and the same.

She looked down at her new form. Admiring her new look and enjoying the feeling of the powerful dark energy that now coursed through her changed body. She was an entirely new woman now.

Amy’s smile grew wide as she touched the ground for the first time since her transformation. She wordlessly walked towards where she came from in the castle, grabbing the emerald that had fallen to the ground in all the chaos. She began to hum to herself a tune that had a haunting melody to it, a new song that she had learned, as she made her way back from where she came. It was time to hunt. Time to find herself a playmate…

Rouge flew towards the large castle in the dead of night. She knew that Amy was sent off here and when she didn’t come to their girls' night out she was a little concerned. The thief wouldn’t admit it but she was feeling more than a bit worried for the girl's safety. The emerald was just a bonus in this case. 

As she approached the castle, she couldn’t shake the feeling of someone watching her every move. Her experience in breaking and entering gave her a sense for this sort of thing. It tickled the hairs on her head and made her weary. As much as she didn't want to go, she steeled herself and walked inside. 

Rouge’s instincts told her to watch out but by then it was too late.

From the shadows of the defunct castle, Amy came up behind her friend. Her hands wrapped around the bat's waist with one arm and another close to her chest. 

	“A-Amy!” Rouge turned to see her friend in the darkened castle, barely able to see her in the partial moonlight. Startled, she tried to hide that she was frightened from the sudden, intimate contact with feigned confidence. “You sure know how to scare a girl, don’t you?”

As the light of the moon poured in, Rouge’s heart raced as she took note of the newly transformed Amy’s red eyes. 

	“Rouge…” Amy spoke, her voice coming out smooth as velvet in the bat’s sensitive ears. “You know how I was always chasing after Sonic?” 

	“Y-yeah?” Rouge felt a sort of relief at hearing the pink girl talk about her favorite topic.

	“All of those times that I said that I love him… I was lying. Lying to everyone, including myself. The truth is, I don't even like boys…” 

Rouge felt Amy’s hand slide up and under her chest plate, the thin fabric underneath doing nothing to protect her from the hedgehog's cold hands. The sensation made her give out a yelp that she wished she could have hidden. The sound made Amy giggle as she continued to explore Rouge’s gorgeous, curvy body. 

	“It’s been hard holding it back for so long. How I truly felt. Being surrounded by so many beautiful women. Baring everything around me. Not able to say or do anything… Latching onto Sonic as my safety net…” 

Amy brought her tongue out, horrifying Rouge as she saw how much longer it was than normal. With no effort, the appendage reached to the other side of her cheek, giving it a quick playful lick that sent shivers down her wings. 

	“Hey, no one would judge you if you’re in-”

	“Yes they would.” Amy quickly cut Rouge off. She grabbed a big handful of her heavy chest and squeezed possessively. Feeling a chill run up her spine, Rouge tried to get away from the rough, lustful groping. It was arousing, sensual, but also felt uncomfortable. Like prey being eyed by a hungry predator. “But I don’t feel that fear anymore. That judgment is gone from my soul. As for my body…”

Amy turned Rouge to look at her. Her ruby eyes captured the bat's sights, keeping her in place as she turned to face the newly vampiric Amy Rose. Amy closed the distance between them, locking her lips with Rouge. Trapped in her own body, Rouge could do nothing as the inside of her mouth was invaded by Amy’s freakishly long tongue, wrestling vigorously with her own tongue as Amy moaned in delight at the Bat’s flavor. Her hands weren’t done playing with the bat's sexy body. Rouge could feel the hedgehog's every groping, sliding finger and every sensation of her affection across the bat's body. Unrestrained, unhesitant and invasive. Consent was clearly not mandatory. It wasn't even considered.

When Amy was done, she stared at Rouge with an unsatisfied look in her eyes. Hunger. She wanted more. She needed more.

Rouge watched the vampire's new black claws move in one sweeping motion, easily slicing through the girls' clothing down the middle. Like a kid on Christmas morning, Amy’s eyes glistened as she marveled at Rouge. She eagerly reached out, wanting to play with her body in its bare state. Instead, she held back and simply laughed as she curled her finger in a motion making Rouge follow her in flight as they moved deeper into the castle. 

As they flew, Rouge found her voice but otherwise couldn’t do anything else.

	“What have you done to Amy?” She asked, her voice left without a thread of her usual playful attitude. 

	“I'm still here, my cute little thief, and I'm better than ever. Free to be my true self.” Amy answered with a sinister, yet sultry tone to her voice. She didn’t turn to look or stop flying as they made it to the bedroom. As they landed, Amy reached and pulled Rouge inside, a delighted smile on her face as the older bat landed on top of her of their new cushy bed. 

Compared to the rest of the castle, it was seemingly untouched by time. Candles, fresh, clean bed sheets. Not a hint of dust or any piece of debris. 

Amy’s heart swam in delight as she finally got to satisfy her desires. Her mouth played with Rouge’s body, tasting the sweet honey that dropped from between the bat's legs. She couldn’t say no. She couldn’t deny herself anything other than the sweet moans befitting a cute bat. As she moved from between Rouge’s legs, Amy resided to launch another kiss. 

However, her attention moved to her slender, tan neck. The sweet smell of perfume, bodywash and other floral scents made her ache in ways she never felt. Amy’s fangs seemed to emerge on their own, growing just big enough to finally peer out from her mouth. Rouge’s blood ran cold as ice. She realized what was about to happen, and there was nothing that she could do to stop it.

The fangs penetrated the bat's neck, and she let out a cry that sounded equal parts pained and orgasmic. It stung, briefly, but it also felt so good. Like as if Rouge had instantly become a masochist in that moment. A feeling of fulfillment flowed through her body as Amy fed on her blood. The hedgehog girl felt more alive than she ever had before in just those few moments together with Rouge. As she enjoyed the sweet red liquid life, her hands never stopped molesting her playmate's body. Sliding her finger between her lips, sliding in and out, pumping in and out and loving the flavors that never seemed to end.

Again and again, Amy didn’t give Rouge a moment to rest. The bat could feel the corruption of vampirism spread throughout her body like ice-water in her veins. Changing both her body and mind. Rouge could feel her teeth lengthen and sharpen. Her fair, tan skin turned pale. Claws sprouting and growing from her fingers. Her eyes turned a dark, blood red, and started to glow. By the time Rouge realized what was happening to her, she welcomed it. She felt the darkness fully consume her soul. The hunger for blood growing within. Rouge screamed in ecstasy as she suddenly had a messy, squirting orgasm. Punctuating the completion of her transformation into a vampire. She was Amy's now. Body and soul. Her eternal minion, ready, willing and eager to serve. Rouge smiles back at her mistress as the two of them embraced each other in a passionate kiss.

	“Welcome to my new kingdom, Rouge…”
