I will be skipping the train scene and the one where Arthur is talking to Harry. Since you guys know all about that from watching the movie or reading the book.

It was raining when Harry and his friends got off the train; meeting them was a boat ride and a magical carriage that rode down to the castle.

The carriage stopped by the castle, letting everyone get off and into the castle as soon as possible before getting soaked.

Harry and his friends went straight to the great hall. Since all their stuff has already been brought up by magic. They made it to their table where they greeted everyone else from their house. He looked over at the tall table, seeing Snape sitting in a different spot this time.

Suddenly a choir emerged in his sight, blocking him from seeing. The choir singing were his classmates, each carrying a giant frog. That's when Harry realized while looking around the side of the staff table, that there was more staff this year. 'I guess Snape had to move to another spot?' The choir ended and parted ways. Harry was able to see his dark teacher again, 'Can't believe I am dating him,' he smiled to himself. He saw him clap at the choir for a bit.

"Welcome, welcome to another year at Hogwarts. Now I would like to say a few words before we all become too befuddled by our excellent feast. First, I'm pleased to welcome Professor R.J Lupin, who's kindly consented to fill the post of Defense of The Dark Arts teacher. Good luck professor!"

Everyone was clapping at this. Well, except for some of the Slytherins of course. Harry noticed Snape applauded only two times, he also didn't seem pleased with Professor Lupin. 'I will see if I can get his attention.' Snape looked over at green. Harry mouthed the words, "You don't seem pleased?" He eyed Lupin then him. To signal what he is trying to ask. The potion master slowly nodded. The young wizard told his friends he was going to the bathroom.

"Potter? Potter?" Harry looked over Malfoy, "is it true you fainted? You actually fainted?" He was about to start laughing. Harry did not know how he found out.

"Just forget it," Hermione suggested, at least for the time being.

Harry agreed; besides, he has another important task to do, looking over the staff table. Going out the great hall doors, he quickly went upstairs to get his invisibility cloak out.

Harry put a silent charm on the staff door, so it didn't squeak when going in. Putting on his cloak, he went inside. Hagrid was standing up and people were clapping, 'Guess something good happened to him?' He sneaked past him while he was up. "On a more disquieting note, at the request of the Ministry of Magic, Hogwarts will until further notice, play host to the dementors of Azkaban."

He was able to sneak past Dumbledore's throne. Making his way to Snape, lightly tabbing him. The potion master got startled but didn't show it. Harry chimed another spell, to be able to talk to only him without others hearing, "Hey, don't worry nobody can hear me now when I am talking to you." His teacher nodded.

"Until such a time as Sirius Black is captured. The dementors will be stationed at every entrance to the grounds."

The young wizard went over to Snape's ear, "What's going on with guy next you?'

His teacher eyed Professor Lupin before whispering, "He used to be a friend of your fathers and did stuff to me," it was too loud with Albus talking for Lupin not to hear. Or anyone else for that matter.

"Ah, I get it now; why are you sitting with him then?"

"He sat next to me to begin with. I was here first."

"Whilst I've been assured their presence will not disrupt our day-to-day activities...a word of caution. Dementors are vicious creatures..."

"One attacked me on the train," he whispered to his teacher. Looking over at his table he noticed his friends were wondering about what he was doing in the bathroom by now.

"They will not distinguish between the one they hunt and the one who gets in their way."

"See you later," Harry whispers back, giving a small pat on his shoulder before leaving. This time sneaking over to front of the tall tables. Going back down and sitting with friends again, taking off his cloak, while his friends were distracted.

"Therefore, I must warn each and every one of you to give them no reason to harm you. It is not in the nature of a dementor to be forgiving. But, you know, happiness can be found, even in the darkest times...if one only remembers to turn on the light."

Harry waited for Snape after the feast was over. "Want to come upstairs with me?" when his teacher got close, handing him his cloak. He followed his student while putting it on. Making him completely invisible. "Was a good gift, huh?" Harry smiled over at him. His friends met up with him outside the great hall. Walking up, they heard someone singing. Getting closer, it was the fat lady in the painting.

"Fortuna Major," Seamus said, annoyed with the singing. Turning to the others. Snape was annoyed with her as well. "Here listen—she won't let me in.

"Fortuna Major," Harry tries again for his friend.

"No, no, no, wait. Wait. Watch this," she said back, holding a wine glass. Harry sideways glanced at Snape. "Ah, ah, ah." Then she suddenly screams in high notes. Making everyone hold their ears. The potion master silenced her with a spell. Undoing it when she stopped. She smashed it against a pillar. She gasps, "Amazing! Just with my voice."

"Fortuna Major," Harry tried again, really annoyed now.

"Yes, alright. Go in," she finally opened the door.

"Thank you. I can't believe she is still doing that," he said to Seamus. While his hand was near Snape.

"I know after three years," Seamus agreed. They both harmonized with, "She can't even sing. Exactly. Unbelievable."

Dean is grossed out by a ghost getting past him, "Oh god." Hermione agreed that was awful.

Harry stayed behind, holding his teacher's hand under the cloak while going upstairs. They made it to the boy's room. Harry sat on the windowpane, getting Snape to sit down beside him on the right side, while others weren't looking. Putting one hand over to his form.

Ron brought some magic jellybeans from his twin brothers, who made them for him. Setting them on top of a trunk. Harry handed Seamus a green one, "Oh, green. That's a monkey." Seamus imitates a monkey, but sort of fails at it, "What is that?"

"You call that a monkey?" Harry laughed.

"Do not give him one again," Ron said jokingly. "Hey, Neville, try an elephant." Neville does an authentic trumpeting of an elephant.

"Ron, catch!" Seamus throws one at him. Ron chews it, swallows and starts roaring like a lion.

"I think we have a winner," Harry said, smiling at his best friend. While rubbing Snape's lower back. He picked a different color, the black one.

"Oh, don't try one of them!" Ron warned, but it was too late as Harry chewed it. "Oh, no!" They started laughing as steam came out of his ears. "Look at his face!"

Snape looked out of the window at the Dementors.

After everyone went to bed. Harry stayed awake with his professor. Taking part of his cloak off for him, "Probably easier to breathe this way," he said in a whisper. Closing his curtains around them. Also, this way Harry could kiss him. "Won't your house be wondering where you are?"

"Not really, they would think I am either in my office or chambers. It is a bit crowded here though." Also, he wants to take off his day clothes and shoes.

They agreed to go down to his chamber instead. This time with Harry under the cloak when they made it to the dungeon. Snape said the password to get into his chamber. Right when they went inside, his student went over to the sofa, sitting down.

"Wait here, while I go get changed."

Harry nodded, feeling the heat from the fire as he waited. A few minutes later, his teacher came back out, wearing his night clothes and blue robe. Harry smiled over, taking his hand, "Come this way," he guided him to his lap. Feeling his teacher's weight when he sat on his knees, it wasn't as bad as the teen thought. The Gryffindor pulled his head down to his level, to kiss him. This time licking Snape's cold lips. Harry breathed hot air on them, grabbing his cold hands to do the same. "Must be depressing to live down here?"

"Prefer being here, rather than in my family's mansion," Harry nodded, "even though they are both not on this planet anymore, I still don't care for it much."

"Because of past memories?" He nodded, "I can understand that professor." Harry went in for another kiss, licking for entrance. Snape opened his mouth in surprise, which gave his student access to roam every inch of his mouth. "I will go to the library tomorrow and find books on this sort of stuff." Snape nodded in reply, "I want to take control of this after all." His teacher was ok with that. "A while back you told me you are ashamed of your body. Is there something I should know about?" His teacher gaped at the question, not wanting to answer, feeling tension growing, "It is ok professor, just tell me?"

"Got major scars, and other disgusting things, my body isn't much to look at."

"Is that why you have your dress shirt buttoned up to your neck?" Snape nodded, looking away; sadness hid behind his eyes, "awes Snape, you are beautiful in my eyes," He looked over at his student, "sorry if that came out weird, but I just wanted you to know how I see you." Harry starts unbuttoning his shirt, "Don't worry...I am still going slow with you. I just want to see some of your skin." He could see one scar near his neck, "will it be ok for me to ask how you got these? You can ask about mine too."

"To you I will be an open book, Potter, but first I need to teach you that spell."

Harry nodded, "Give me detention with you and teach me?" he touched the line on his neck, "This one was very close to your Adam's apple." Snape nodded. His student went down to kiss it. "So, Lupin was my father's friend, huh?" he raised an eyebrow at why Harry is bringing this up, at a time like this, "I am in his class tomorrow, I am wondering if I should be nice or not to him?" He thought of that, "Now that I think about it, he did save my life today from the dementor."

"You were attacked on the train, right?" He nodded, "I heard about the fainting part."

"I heard someone screaming while being unconscious, a woman," Harry thought about this, "I think it was my mother, you know? That night when she got killed."

Snape gapped at that, looking away. His student kissed him on his forehead, "I want to forget everything that reminds me of your mother. I give you permission to keep anything I have from her."

The teen was shocked at this, 'It took three years to get this far.' "Snape...ok I will help you. When should we start?"

His teacher looked at the clock, "Perhaps tomorrow, it is getting late. I have classes."

Harry was cool with that, "Shall I tuck you in?" Snape glared over, "I mean it?"

"Think I am a little old for that, Potter," the teen pouted on that, "don't give me that, Potter." He gets off Harry's leg.

"Fine, good night then, professor," he kissed Snape.

It feels nice for the dungeon bat to be held like this, it would also be nice if someone tucked him in for once in his life, been a long time since someone did, even as a child, "Fine, Potter. Do what you like." Harry smirked at that, taking his teacher's hand, leading him to his bedroom.
