A/N: I DON'T OWN ANY OF THE CHARACTERS EXCEPT FOR ANNABELLE THE REST BELONG TO THE QUEEN J. K. ROWLING.
ANNA'S P. O. V
It was Christmas night after the Yule ball that Hogwarts was hosting for the Triwizard Tournament.
I went with one of my only friends, George Weasley, and I had a blast.
You see despite being a Slytherin, no one in my house likes me. Why you may ask, well last year Marcus Flint let it slip about my father's condition and they turned on me faster than you can say Merlin.
My father is Remus Lupin, my mother is Lily Potter nee Evans. I have waist length red hair and icy blue eyes.
I was walking with George back to the Slytherin common room. When we got to the corner by the common room we stopped. George pulled out a square black box.
"Happy birthday Anna." He said handing it to me.
I opened it to see a black bracelet with a heart in the middle.

"Thank you George I love it. I had a blast tonight" I said giving him a hug.
"Me too. You looked breathtaking tonight Anna." He said.
I was wearing a black dress with a corset tie on the back.

And long black Stelletos heel boots.

"Thanks you looked very handsome tonight." I said.
George kissed my cheek and said, "thanks goodnight Anna."
"Goodnight George." I said.
Once he left I walked towards the hidden door to say the password.
"Miss. Lupin." I turned to see Professor Snape walking towards me.
"Yes sir?" I asked.
"Did you forget that you still have to do your rounds tonight?" He asked me.
"No sir, I was just going to change, I still have..." I checked my watch to see that it was already midnight, "shit!" I said.
"What was that Miss. Lupin?" He asked.
I looked up at him, "sorry sir, I will start my rounds now." I said.
"Good girl, now get going." He said as he walked by me.
I walked back upstairs to look for Marcus Flint the other Slytherin prefect. I found him waiting for me in front of the Great Hall.
"Sorry Flint, I lost track of time." I said.
"Whatever, I'll take the dungeons to the third floor, you can take the rest." He said and walked away.
I was on the seventh floor next to the tapestry of Barnabas the Barmy when I saw a door that I knew for sure wasn't there before, I opened the door and walked in and after closing the door I turned around to see Angelina Johnson being suspend from the ceiling and Fred Weasley pounding into her.
The room itself was hard to describe.

I turned to go find a professor when a pair of arms went around my waist and a hand covering my mouth.
"Shh. It's not what you're thinking." A voice whispered in my ear.
I turned in the man's arms, the man had red hair that went to his shoulders, he had a broad, good-natured face. Which was weather beaten and tanned, his arms were muscular and one had a large, shiny burn on it.

"Charlie." I said.
"Shit Anna." He said.
"What is this?" I asked.
"Do you know what BDSM is?" He asked.
"No." I said.
"Are you a virgin, Anna?" He asked.
"No. What is BDSM Charlie?" I asked him blushing.
He turned me back around to face Fred and Angelina and said, "well, BDSM, is a variety of erotic practices of Bondage, Discipline, Dominance, Submission, Sadism, and Masochism, BDSM. A dominant is a sexual participant who takes on the role of the superior and often controls the submissive, being a good dominant involves much more then being able to control and gives orders to others. A good dominant will also be able to practice self-control and respect their submissive. Dominants should also be responsible enough to decrease the intensity or stop a scene altogether when a Safeword is spoken."
"What about a submissive?" I asked.
"A submissive is a sexual participant who willingly gives up some or all control to a dominant partner. There are varying degrees of Dom/Sub relationships. Some men and women only play at being submissive during certain times, such as during sex or when in a BDSM club. Others may live as full-time submissive and relinquishing control to their dominants in all aspects of their lives." He said
"Ok.but why is this..." I started but stopped embarrassed.
"Turning you on?" He said.
I nodded blushing.
"It often takes a surprise encounter or unexpected exposure for people to become interested in this lifestyle." (SnowBlindLissaDream is to be credited for this explanation.) He said as his hands started to roam my body.
"What are you doing?" I moaned out.
"Sorry." He said stilling his hands on my stomach.
"I should..." I started to say but was interrupted by Fred grunting and laying his head on Angie's back.
Fred then slipped out and zipped up. He then helped Angie down and untied her. He helped her back into her dress.
When Fred turned to look at Charlie his eyes went wide in shock to see me standing in Charlie's arms.
"Anna what are you doing here?" Fred asked.
"I...um...was doing my rounds when I seen this door and decided to investigate." I said.
"Shit. I forgot to hide the door." Charlie moaned placing his head into my neck.
"Anna, please don't tell anyone." Angie asked.
"I won't tell anyone Angie." I said pulling myself out of Charlie's arms.
"Thank you. Oh happy birthday." She said hugging me.
"You're seventeen now right?" Fred asked grinning hugging me.
"You know I am Freddie." I said laughing as I returned the hug.
"Happy birthday Anna." Charlie said.
"Thanks." I said blushing.
I walked away to give them some privacy. I was pulled out of my thoughts when Fred said, "Well we better get back to the common room. Bye guys."
I found myself alone with Charlie, and for some reason I was extremely nervous.
Charlie chuckled and said, "there's no need to be nervous, I won't do anything unless you want me to."
"I know, but I do have some questions." I said.
"Ok. But let's sit on the bed and I will try to answer them to the best of my abilities." He said as he led me to the bed.
"First, what is this room?" I asked.
"This is the room of requirement. It will become anything you need." He said,
"Ok. How do you know if you are a dominate or a submissive?" I asked.
"When you understood what was happening what turned you on the most, Fred taking control or Angelina relinquishing her control?" He asked.
I sat there thinking back to the scene and said, "Angie relinquishing her control."
"I thought so. Are you in control a lot during the day?" He asked.
"Yeah. I'm a prefect." I said.
"If you want we could do a scene to see if you are a sexual submissive." He said.
I thought about it. I took a deep breath and said, "yes, I would like that."
His brown eyes went dark with lust.
"Ok. Then from now till I tell you so you are to address me as Master or sir. Do you understand?" He said.
"Yes sir." I said.
"Good. You will also follow my every command. Do you understand?" He said.
"Yes sir." I said,
"Good. I am going to ask you some questions. Are you ok with me tying you down?" He asked.
"Yes sir." I said.
"Are you comfortable with penetration?" He asked.
"Yes sir." I said
"Ok. Now get up and take everything off." He demanded.
I got up on shaky knees and reached behind me to untie my dress when I felt his hands grab my hands and untie my dress himself.
"Thank you sir." I said as I slipped out of my dress and laid it on the chair. I took off my thong and laid it on my dress. Then took off my boots and placed them under the chair.
I turned around to see Charlie in just pants.
"Come here and kneel at my feet." He said.
I walked over and insult
Knelt down, where I was sitting on my knees with my hands on my lap.
"Good girl. Another definition, Safeword is used when one participant is uncomfortable and wants the scene to be less intense or stop altogether. For example you can use yellow for slow down and red for stop. Now choose a Safeword." He said
"Could we just use red sir?" I asked.
"Ok. Red it is. Now finish undressing me." He said.
I slowly unzipped his pants and slipped them off along with his boxers, I Wandlessly sent them over by my dress.
"Show me how you give head." He said.
I slowly grabbed him and licked around his head, making him groan in pleasure. I slowly brought him into my mouth bobbing my head up and down going deeper every time.
"Stop. Get on the bed and lay down in the middle." He said.
I did as I was told. He walked to the dresser by the bed and pulled out four long Strands of black rope.
"I'm going to tie you up now pet." He said running a stand of rope across my ribs.
He then grabbed my right arm and lifted it up and over my head and tied it through one of the rings in the wall, he did the same thing to my left arm. Then with his hands traveling down my body he grabbed my ankles and tied then to a pole on each side of the bed.
When he was done he stood back and looked at me spread open for him. He slowly climbed on top of me.
"Can I kiss you pet?" He asked.
"Please sir?" I begged.
He leaned down and placed his lips against mine, he licked my lips looking for permission in which I granted instantly.
His lips traveled down to my neck as his hands were roaming my body.
"You're soaked pet." He said as he knelt down in between my knees and attached his mouth to my clit and started sucking on it, as he pushed his middle finger into me making me scream out in extasey.
When I came he climbed back on top of me and thrusted into me.
"Gods yes Master." I moaned.
He continued pounding into me with every thrust I felt the tightening in my gut. And with a final thrust of his hips the dam released and while I was coming down from my high Charlie released his seed into me.
He collapsed on top of me with his head in the crook of my neck. Once we caught our breath he exited me and untied me.
"Thank you sir." I said as he was rubbing the circulation back into my arms.
"Charlie now love." He said as he walked over to grab his pants and my clothes and boots.
I checked my watch after I slipped on my dress to see that it had stopped working.
"Your watch isn't broken, the room had stopped time." He said retying up my dress.
"Oh, ok. I um need to get back to my common room." I sauce
Said slipping my shoes back on.
"Let me train you to be a submissive?" He asked.
"I'd like that." I said.
"Ok. I will send you a contract to look over and sign." He said giving me a kiss goodnight.
Once I got back to the common room I laid down on the couch and fell asleep as soon as my head hit my pillow
