Vampires

  The moon shone full as Ben approached an old mansion. There have been reports it was haunted and he--dared by his friends--was going to prove himself by staying the night. The front door opened slowly with a loud creak before he was even close to touching it and he entered. The old gas lamps suddenly turned on as the door slammed shut behind him. In the light, his features were a little clearer to see. He had short dirty blonde hair and hazel eyes and wore a plain white tee, a pair of blue jeans and green and red sneakers.
  As he walked through the corridors, looking for a good place to sleep, he started hearing faint sounds, more particularly the sound of a woman giggling. He came across what appeared to be the master bedroom, where the giggling was the loudest. He approached the large bed and the giggling stopped.
  "My my, a new playmate is here~" a seductive voice said from behind him.
  "Whaa?!?" Ben turned around and saw a woman. She was the same height as him with shoulder-length jet black hair, bright red eyes, a large bust and she wore a dark red Victorian-style dress. She stepped toward him and placed her hand on his cheek.
  "Do not be afraid. My name is Skye." She smiled as she saw his height slowly shrink down exactly one inch from 5'3 and his hair brightened to white. He closed his eyes as his face unnoticably shifted to look more feminine and his hair started to grow longer. His eyes were now violet when he opened them again. Her hand moved down and she pressed her long red nails onto his neck which also became smaller and his Adam's Apple disappeared. His hair was now just past his shoulders, which had become smaller and his arms and hands slimmed down and his fingers became longer with the nails extending as they became covered in black polish. His spine then arched forward as the rest of his frame compacted, which didn't go unnoticed.
  "Wuh-what's going on!?" He looked at her, his eyes now red, and was surprised at his now-higher voice.
  "Relax. It will be over soon." He felt a sharp pressure at his waist and a tingling in his chest and wrapped his arms around his stomach. It was then that he saw his nipples pop out and two mounds ballooned out from behind them. As this was happening, fat was moving toward his hips and ass and almost split his pants apart. His hair had stopped growing at the small of his back as his legs changed to match his arms and his feet became small and dainty, almost able to slip out of his shoes easily.
  "Wuh-why are you doing this!?" he shouted as he felt an intense pressure on his groin, making him collapse.
  "Because I'm lonely..."
  The pain intensified as his testicles were slurped up inside him, effectively becoming a brand new vagina, turning Ben into a woman and changing into a more intense wave of pleasure. The remaining part, her penis, was shrinking and retracting until it too changed into her clitoris.
  She tried to get on her feet, but quickly lost her balance and fell on the bed. "I-I'm a girl now...?" She looked down at herself and saw that her clothes woo were changing. First they became black and pink and she saw her pant legs fuse together and become a different fabric before puffing out into a frilled skirt. Her shoes changed into three-inch stiletto heels and her shirt became frilled to match the skirt. A bow then appeared in her hair.
  "You look beautiful."
  "Th-thank you..." She blushed. "Why'd you turn me into a girl, though?"
  "Because I was lonely. There aren't any other vampires for me to love."
  "V-vampire??"
  She nodded. "It's what I am. And now so are you."
  "I am??"
  "Yes." She kissed her. "We are the same. And now, we can keep each other company. Perhaps make a new playmate out of any others that enter."
  "New playmates?" She smiled, getting used to the idea. "Sounds like a lot of fun!"
  "Hehe, I know!" She kissed her again. "But for now, we're fine."

  A few of Ben's friends came to the mansion to look for him. And, of course, they never left...
