Chapter One:

Potions Group

'Double Potions with the Gryffindors,' Severina thought walking down to the dungeons. She had nearly all but one of Gryffindors boy's in her year made her life a living hell. Serafina walked into class ignoring the comments from Black, Potter, and Black's girlfriend as she sat between Narcissa Black and Athalia Tripe.

"You okay," Narcissa mumbled into her ear.

"I'm fine," Severina said quickly pulling out her potions book and began making notes on the Potion Slughorn had written on the board.

"Had a good Christmas?" Athalia smiled, "We barely heard from you and Regulus."

"Oh, lost track of time," Severina mumbled.

"Regulus said you barely left the room," Narcissa said looking over her.

"Would you want to be around your Aunt being a filthy half-breed that is rotting her son's mind," sneered Severina quoting Walburga Black's words before glancing back to see Sirius smirking at her. If she told Lia and Cissa how she really spent her Christmas they'd have her commented.

She was in Sirius's old room at #12 Grimmauld Place. The room was decorated with Gryffindor colors and banners and posters of bikini-clad Muggle women and muggle motorbikes. It made her sick, but apparently this was the reject room.

Severina sighed and shifted restlessly on the covers of the old bed. The whole room smelt like Sirius and Gods did he smell good. Her idiotic crush on the boy revealing itself, she had no idea why she was crushing on the bane of her existence.

She felt pathetic laying on his bed, nearly naked, and smelling his pillow. She looked over and noticed the window open.

She reached under the pillow at her head, pulling her wand out discretely, ready to pounce if necessary. Choosing the element of surprise, she bolted upright, bringing her wand from behind her head and sweeping the room with deadly precision.

"Don't shoot," came the lazy, almost amused drawl from the window sill.

Severina directed her wand there, never letting her hand waver even as her mind shut down and she glared.

"What are you doing here mutt," Serafina hissed.

Sirius chuckled taking off his leather jacket, "The last I checked this was my room."

"They call it the reject room now. It's where your mother puts people that don't fit in her old so perfect pureblood life," Severina sneered.

"Mother doesn't like you?" Sirius asked staring down at her with an intensity that was almost piercing.

"What are you looking at," glared Severina.

"You have a nice body under all those school robes," he said with blatant honesty.

"What do you want," said Severina suddenly.

A glint came into Sirius' eyes. "You know what."

She bit her lip until it almost bled looking up at him. That small, lazy smirk crept up his face once again, seeing the willingness in her eyes. Then his eye slid down to a cluster of scars before looking back at her face.

"I'm sorry."

That hit Snape hard. Sorry? Sirius Black, sorry?

Black now gazed off into the darkness, ignoring Severina' slightly gaped mouth and widened eyes. He stuffed his hands in his pockets and cocked his head back at Serafina. She could see this wasn't a joke so she crawled over to him.

"I never thought I'd hear you say," Severina said looking into his eyes. Without thinking, she leaned towards him and pressed her lips on his.

There was a stunned expression on his face. "Why did you do that?" he asked her.

~*~*~*~SMUT SCENE AHEAD ~*~*~*~

"Because you wanted me to," Severina said biting her lip. Sirius pushed her back on bed and deepened the kiss, his wet lips claiming her slightly soft ones with a fiery passion. Severina knew she should put a stop to this, that she was reacting from pure shock and he was taking advantage of her semi-naked state - but she merely wrapped her arms around his neck and pulled him to her.

"You drive me mad," Sirius murmured kissing each scar and bruise made by the Whomping Willow all those months ago. He clutched her hips peeling off Severina's black laced underwear.

Severina braces her hands on his shoulders, closing her eyes in anticipation. His lips caress her hip bones and then he places an open mouthed kiss directly at her core.

"Oh Gods, Black," Snape moaned loudly.

"Say my name," Sirius smirked before slowly his tongue glides inside and finds her clit.

"Gods, Sirius! Please, don't stop."

She moans when he regards her pleas and sucks that sensitive bundle of nerves into his mouth. Hearing her moan sends more blood rushing to his swollen cock. Severina trembles from the way his tongue twist and turns inside her. Sirius smirked to send her over the edge he pinches her clit between his forefinger and thumb then twists.

"Sirius," she moaned as her whole body gives out when the orgasm hits her. He continues to lap at her juices letting her ride out her climax. When he was done he crawled next to her watching her stead herself.

She turned her head to glare at him and threaten him, but before she could he caught her lips in a searing kiss.

"I want you," Sirius whisper into her ear.

Severina moaned loudly as she started to rip of the remaining of Sirius's clothes. "You always get what you want don't you?"

"Yes, I do," Sirius smirked kissing her once again sliding his tongue inside her mouth to slide against hers tasting her. Lungs burning from lack of oxygen Sirius moved his mouth from Severina's and lays kisses along her jaw. As he does this the hand that was in her hair moves down and unhooks her bra.

Sirius threw her down on the bed greedily drink in her naked form as he pulled off his jeans. Severina's eyes widen staring at his swollen member. Sirius smirked as he crawled back onto the bed and went for her lips again.

"Do you want me?" Sirius whispered in her ear.

Severina nodded, biting her lip.

"Then tell me what you want me to do," Sirius said huskily as he caress her breast.

"Take me, fuck me, do whatever you want just make me yours." Severina whimpered not believing the words that were coming out her. She spread her legs as Sirius hovered above her. Severina placed kisses up his neck as her entered her. But suddenly I felt a surge of unbearable pain and bit down on Sirius's neck so hard that she could taste the blood now gushing into her mouth.

Sirius hissed looking down, "Hey, did I hurt you?"

"No," She said breathlessly pulling away from his neck. "I've just never done this before."

There was a look of astonishment on his face. He gently wiped the blood off her mouth as he slowly slid out of her. His thrusts were slowly and gently trying to make it as pains as possible. The pain faded replaced with pleasure.

"You feel so good," Sirius moaned into her ear.

"Oh gods, deeper more," Severina plead.

Sirius thrust deeper into her, their hands and mouths roam everywhere they can reach. Her nails dig into the flesh of his back creating red marks while his hands grip hard at her hips and bottom leaving bruises. The room fills with the sound of flesh slapping against flesh.

Severina's moans turn into half said words as her second orgasm of the day. Both teens reached their climax together.

~*~*~*~ END OF SMUT~*~*~*~

Their bodies were still hot and sweaty as he pulled out of her. He lay down next to her and looked down between her legs. There was a patch of blood on the sheet. He didn't say anything just pulled her closer to him.

She lost her virginity to him and when she woke up he was gone, yet he came back every night for more. If it weren't for the cum and blood all over the sheets she would have believed it was just a dream.

Her head snapped as Professor Slughorn waddled into the classroom, his bulging stomach a couple of inches ahead of him.

"Today I will be assigning groups to make very complicated potions. Felix Felicis can anyone here tell me what that is?"

Lily's hand shot in the air.

"Miss Evans"

"It's liquid luck. It makes you lucky!"

"Correct, 10 points to Gryffindor. Can anyone tell me it's characteristics?"

Again Lily's hand shot in the air.

"Miss Evans"

"It is said to look like molten gold."

"Correct, another 10 points to Gryffindor. Now can anyone tell me it's Side effects."

The class was silence not even Evan. Severina felt Narcissa elbow her so she raised her hand.

"Miss Snape"

"Overuse can cause giddiness and reckless behavior. It's extremely toxic in large quantities. It's highly disastrous to brew incorrectly."

"Correct, 10 points to Slytherin. Now you will be working in groups,"

Severina sighed, she knew Professor Slughorn would put her with some of the dumbest students in the class and she would end up doing all the work.

"Severina Snape, Lily Evans, Remus Lupin, James Potter and Sirius Black," Slughorn said lastly.

"WHAT! Professor that is a horrible idea," Severina protested. "Me with Black and Potter! We'd kill each other!"

"Miss Snape you have worked with both Mr. Lupin and Ms. Evans in the pass and it since to have helped there grades," Professor Slughorn said in stern tone.

"At least you have Lupin and Evan who are intelligent. We're stuck with the Neanderthals and the rat," Narcissa sighed looking over a Mulciber and Avery than at Pettigrew.

"Let's just get this over with," Severina sighed walking over to the table where the Gryffindors sat.

The talking between the four Gryffindors stopped almost immediately. Severina ignored all there gaze pulling a black and green hair ribbon out of her bag and tied her hair back to keep it out of her face. She looked up to see Sirius with a small smile on his face.

"So, are you going to stare or are we going to get to work," Severina glared.

"Well let's grab a cauldron," James suggested.

"Wrong, you cannot simply grab a cauldron and start brewing such delicate potion," Severina explained with an annoyed tone.

"You speak like you've brewed this potion before," Sirius spoke.

Snape's jaw click, "I'm extraordinarily talented at potions. I have made thing that not even seventh years are making. A Pewter Cauldron it will add an extra few days of brewing but it will give the best results."

"Um, that sound good," Lily smiled meekly.

Before she could say anything an origami swan flew in front of her. She gently unfolded it to see Narcissa neat handwriting;

IS THAT A HICKEY!?

Severina could feel her face go red and her hand instantly shot up to side of her neck Sirius had assaulted the night before. She had to she had gotten rid of them all.

"Bastard," She mumbled under her breath before wiping around to glare at Narcissa and Athalia. She let out a long breath before turn back to the group. Sirius was looking at her with that smug look.

Sorry if Severina isn't like Severus. She wasn't just based of Snape so was base off Severus Snape (Mostly), Jade West from victorious, and Violet Baudelaire from a series of unfortunate events.

Again I'm sorry for any grammar mistakes…

I've been on a genderbender kick. This is my first smut ever! I hope it was horrible. I may keep writing this so stay tuned and Review
