Christmas Holiday. Normally I would hae gone home, but not this year. It was more important that I stay at Hogwarts. And maybe something else might happen as well.

I walked into Professor Snape's office. He was grading papers, and didn't look up at me as I entered and closed the door behind me.

"Finish your potion from yesterday, Miss Granger," he said without taking his eyes or quill away from the paper.

"Yes, sir," I said, putting my bag down and getting to work.

I looked back at him several times, but he never looked at me. Had I done something wrong before?

Finally after an entire hour, he spoke to me.

"Are you going home for Christmas?" he asked.

I turned around to look at him, but he was still focused on his work." Um, no," I said.

"So you will be here the entire break?" he asked, finally raising his eyes to meet mine.

"Yes," I said.

"Good." He paused. "Are you finished with your potion?"

"Um, yes, sir." I set my want down on the table next to the cauldron.

Professor Snape got up from his desk, walked over to me and inspected my potion.

"Excellent work, Miss Granger. Ten points to Gryffindor."

I stood still next to him, waiting for anything.

"Why don't you come with me, Miss Granger. I have something to show you."

He turned around and walked to the back corner of his office. I followed him, and once we reached the wall, a door appeared. He opened it, and we stepped inside. Behind the door was obviously a living space. It was dark and small, but also cozy. There was a small living area with a couch and fireplace, and in the back was a large bed. Professor Snape kept walking toward the bed. Was he finally going to make love to me somewhere other than the cold floor of his office? Once we reached the bed together, he turned back to me.

"Strip," he said, and I obeyed, immediately taking off my entire uniform.

Once I was bare in front of him, he just looked me over for a couple of minutes.

"Professor-"

"-Quiet," he said. "Lie on the bed."

I did as I was told, slowly climbing onto the large bed, lying on my back, my knees together and I hands just below my breasts. He climbed on top of me, and I felt a nervous rush. He didn't touch me, just hovered over me, staring at my body.

Suddenly he grabbed both of my hands and held them over my head with one hand. With his other, he pulled out his wand and bound my wrists together above my head. Then he sat back and spread my legs apart, binding each of my ankles in place. I couldn't move any of my limbs as I was spread wide open for him.

I looked up at him as he took of his robe and shirt and then pulled his hard cock out of his trousers. He started stroking it, just looking at me bound in front of him.

He slowly came closer to me, sitting his knees over my chest and pushed his cock into my mouth. I could barely move my head to suck him. Then he started thrusting into my mouth, grabbing my hair and hitting my back of my throat. I gagged and he pulled out, rubbing the head of his cock over my lips. Then he slowly traced down my body with his cock, circling my nipples and down my abdomen until reaching my pussy and suddenly thrust into me.

I screamed and moaned as immediately he fucked me hard and fast. I wanted to grab onto anything, but I still couldn't move. He grabbed my hips and sunk deep into me. I screamed again as I came and he fucked me through my orgasm.

"OH PROFESSOR! OH, I 'M CUMMING!"

All he did was pound into me harder. My orgasm lasted longer than I thought possible.

When I finally stopped, he kept fucking me.

"Oh, god, Professor…." I moaned softly.

He slowed down, grinding into me, pushing all the way in and pulling all the way out. With one hand he reached forward to squeeze my nipple and with the other he rubbed my clitoris.

He grunted and groaned as I got close to cumming again. He picked up his pace again, still massaging my breasts and clit.

"Oh, Professor! I'm going to cum again!" I moaned, looking up at him.

He dropped down on top of me, pounding into my pussy, and grabbed a handful of my hair. He groaned loudly into my ear as I felt his cum shoot inside me. I screamed as I came again.

After we finished, we lied there panting. Finally, he got up and pulled out of me. I felt his cum leak out of my hole.

Professor Snape stood up and started putting his clothes back on.

"Professor, can I…"

"You're going to stay here for a couple of days, until I'm done with you," he said.

"But,"

"No buts," he said.

It excited me, but also frightened me. What was he going to do? As all these thoughts ran through my head, he turned around and walked back out to his office. I didn't know how long he was going to be, so I closed my eyes and tried to rest.

As I slept, I dreamt of Professor Snape's huge cock inside me. I could almost feel it stretching my holes. Until I suddenly realized I wasn't just imagining it. I opened my eyes to see Professor Snape on top of me. I screamed in surprise as I felt his cock deep inside my arsehole. He reached up and covered my mouth, and started fucking my harder.

His eyes were closed and he was grunting. I moaned into his hand as he gave the hardest thrust I ever felt into me, and then I felt his cum shoot inside me again. I could feel his cock pulse as his load filled my hole.

He took his hand from my mouth, pulled out of me, and fell onto the opposite side of the bed.

Suddenly I woke up again. I looked over to see the Professor Snape gone again, but to my surprise, I was on my side. I moved my stiff arms and legs, sitting up and stretching. I looked around the living space, wondering if there was a lavatory. There was another door. I didn't know where it led, so I tried it out. As I opened to door, to my relief, there was a toilet.

I went back to the bed and saw a glass of water on the table next to where I was. I picked it up and gulped it down in seconds.

I didn't know where Professor Snape was, and I didn't know when he would be back, but I assumed he wanted me to stay here. I didn't want to make him angry, so I put my skirt and blouse back on, and went to sit next to the fireplace. My back was next to the couch, so I pulled out a book and read.

I almost finished my book when I heard the door open. I looked up to see Professor Snape enter. He eyes me on the floor, closed the door behind him, and walked toward me.

"Miss Granger…"

"Yes?" I closed me book, set it on the floor and stood up.

"I trusted your judgement enough to know what you were and were not allowed to do… however… what made you think you were allowed to get clothed?"

"I… I was…"

"Take them off," he ordered.

I immediately did as I was told.

"Get back to the bed."

"Yes, sir."

I walked back to the back and lie back on my back.

"Turn over," he said, taking off his clothes as well.

I turned over, raising my bum in the air a bit for him. Immediately I felt him grab my hands again, placing them over my head and binding them in place. He grabbed my hips and placed my bum exactly where he wanted them before binding my ankles again.

"I think, a bit of punishment is in order for you to learn your lesson this time, Miss Granger."

"Um… sure." I said hesitantly.

Suddenly there was a sharp pain on my bum. I yelped as he struck each cheek four times each.

"Oh, Professor, please…" I started begging him to stop, before he grabbed each cheek, pulling them apart and started licking my hole. I moaned and pushed back against him as he ate both my holes. Then he slipped two fingers in each hole, thrusting them in and out. I moaned into the pillow in front of me as he fingered me with one hand and took turns striking my cheeks with the other.

"Professor, I'm going to cum!" I yelled into the pillow as I got closer. Just before I released, he pulled his fingers out of me. "Mmm, professor, please."

"Not yet." Then I felt something harder and bigger than his cock pushing against my arsehole. "Relax," he groaned and whatever it was popped inside. It was huge.

"Oh, Professor, it hurts…"

"You're being punished, remember?"

I groaned as he pushed it farther into me until I finally felt the hilt of it reach the outside. Then without warning he sunk his cock into my pussy, slowly fucking me and keeping the other object deep inside my arse. I moaned at the intense full feeling as he slowly gained momentum, eventually pounding into my pussy.

"Oh, Professor!" I screamed as I came and he struck my cheeks again. They were so sore it felt both raw and numb.

He fucked me harder as I came, and suddenly he pulled the other object out of my arse, pulled his cock out of my pussy, and plunged his cock into my arse, fucking me harder than ever before. He grunted and gripped my hips as he pounded into me. Finally he leaned forward, reaching around to grab my breasts and he came inside me again.

He pulled out of me, his cum leaking from my hole. He undid my bindings and I dropped to my stomach, panting.

"I have errands to run. Stay here and don't get dressed." He put his clothes back on and left again.

Over the next few days I stayed in his living quarters. I woke up in the middle of the night to him inside me. One morning I only sucked him, and I wasn't allowed to stop until he came. He used all of my holes however and whenever he wanted, and I loved it. It was the most intense week of my life and I don't think I'll ever forget it.
