Lion and the Snake

Chapter One- Visiting the Past

Severus was putting away his things in his dungeon class room, when Albus Dumbledore walked in. "Albus, what do I the pleasure of your visit." Albus sat down next to Severus' desk.

"I have thought long an hard about the teacher of Defense Against the Dark Arts." Severus set up in his chair. "And I think Remus Lupin will do a great job." Severus' jaw draped. "I need you to make him wolfsbane potions this year."

"Yes sir."

"Great. I will let you get back to unpacking." Albus strode from the room.

Remus came onto the train early that day. He wanted to be unseen until the he got to Hogwarts. He settled into one the cars at the end of the train. He put his things away and sat down and soon fell asleep.

Hermione, Ron, and Harry walked down the hallway as the train picked up speed.

"This is the only spot left." Hermione said as they came to the end of the train. They slip inside, they looked at a Remus, not knowing who he was, slumped against the window, asleep.

"Who do you reckon he is?" Ron asked looking over at Remus.

"Professor R.J. Lupin." Hermione responded

Ron looked puzzled. "You know everything. How is it she knows everything?"

Hermione laughed. "It's on his suitcase."

"Is he really asleep?" Harry asked eyeing him wearily.

"He seems to be. Why? What is it, Harry?" Harry close the door.

Later…

"Let me get this straight. Sirius Black escaped from Azkaban to come after you?" Ron's eyes were the size off saucers.

"Yes."

"But they'll catch Black, won't they? I mean... eventually?" Hermione tried to reason.

"Sure. Of course, no one's ever broken out of Azkaban before and he's a raving, murderous lunatic…" Hermione elbowed Ron. Then, the compartment rattled, the lanterns flickers and the train came to a stop. Hermione slid down the seat to look out the window then at her watch.

"Why are we stopping? We can't be there yet…"Hermione asked as she saw her breath. Harry looked worried

"Don't know, maybe we've broken down?"

"Ouch! Ron, that was my foot!" Hermione hit Ron but he is looking out side.

"There's something moving out there. I think...people are coming aboard." The train jerked suddenly. The window froze up. "Bloody hell. What's happening?." Remus eyes open he looked at the kids but closed his eyes until he was needed. A slimy, dark hand griped the half-open compartment door, pushed it aside. The creature that followed the hand was the spiting image of death itself. Lupin opened his eyes, seeing the dementor, he stood and pointed his wand the creature. A bright light came out and made the dementor go away. Remus looked at Harry, the poor boy was unconscious on the seatWith a gasped Harry opened his eyes.

"Harry? Harry, are you all right?" Hermione's troubled face hovered above him. Harry nodded, and sat up. Ron looked pale and nervous, he gave Harry his classes.

"Thanks." Harry put them on. Remus was setting on the others side, he broke of a ragged piece of chocolate off in his hands and held it out for Harry.

"Chocolate. Eat. It'll help."

"What was that…that thing?" Harry took the chocolate.

"A Dementor, one of the guards of Azkaban., it's gone now. It was searching the train for Sirius Black. Now, if you will excuse me, I need to have a word with the driver." He pointed to the chocolate. "Eat, it'll help." He slipped out and went to talk to the driver.

As the students went in their carriages Remus got one to himself. He felt it when he went through the barrier, because he was muggle born. He walked into the Grate hall before the students. It was how he remembered. He walked to the head table and took a seat. Soon the teachers came in. His eyes caught Severus' eyes. Those black eyes filled with love, but the light went out as soon as Severus sat down. Remus tried to keep his mind on dinner but he would steal glances of the Slytherin next to him. During the dinner Severus slipped him a paper. Remus read it as Severus got up:

Meet me in my room after dinner.

Remus tried to eat but he was to jittery. He wanted dinner to be over. As so as it was Remus was out of the room and down in the dungeon. He knocked on Severus door and entered. The potion master was standing In the door way of his room.

"Well if it isn't the devil himself." Severus had a smile on his lips.

"You remembered Severus I thought you had turned on me, and forgotten."

"Forgotten? Who could forget your taste." Remus walked to Severus stood in front of him.

"Should I make the first move?" Remus raised his eye brow, but Severus made it. Taking Remus in his arms and capturing his lips. Remus let Severus' tongue into his mouth.

"Severus you always took my breath away."

"That is nothing." Severus grabbed Remus hand and threw him on the bed. Severus then locked the door. He flicked his wand to where Remus' hands we sealed together.

"I see you are still incharge?"

"Would you have it any other way." Severus flicked his wand and Remus' clothes were gone.

"No." Severus bent and took Remus cock onto his mouth. Remus gasped. "Severus you are very skilled with…" Remus couldn't finish his words because Severus lightly bit at his member, sending pleasure to his very core. Remus bucked his hips to the movement of Severus mouth. Remus felt himself come in Severus mouth. Severus would not let a drop fall form his lip. After he licked Remus clean he removed his clothes and got up next to Remus. He flicked his wand a Remus' hands were set free.

"You took my job." Severus' black eyes were angry.

"Severus you are not going to hurt me, are you." Severus could be mean and torturous when he was mad. The madness fell from Severus eyes. He gently kissed Remus brow.

"No, I can never bring myself to do that to you again. I will not lose you again." Severus pulled out his wand. The lube filled his hand he put it on his member. Then he got on top of Remus and pushed in. Remus grabbed Severus' arms. Severus smiled. "You always begged me to fuck you."

"I will not beg. I am not a dog Severus."

"No, you're my lover." Severus pushed just inside him. Severus bit his lip as he eased in, going slowly, not wanting to hurt Remus, but Remus' body felt so perfect beneath him, and he wanted to drive himself into that tight heat, claiming it as his own. Once he was fully buried within Remus, he took is mouth and put is one of Remus' nipples. Remus moaned and Severus began thrusting deep. Remus moving to meet each thrust, grinding his hips against Severus' as if unable to get him deep enough. Remus closed his eyes, his head tossing on the pillow as he clutched Severus' back and rocked with him, matching him thrust for thrust; his body was relaxed, yielding and open to Severus completely. Severus let go of his nipple and threw his head back, coming in Remus and calling his name as many times as his breath would let him. Then he collapsed at Remus' side.

"I have waited for that for some time." Remus panted, Severus took Remus lips on his. Then he laid back. "I need to go get ready for my class." Severus looked at him.

"Go ahead. But when I call for you, come." Remus smiled then got dress and walked out of the room.
