Impetus

Severus x Lily

Every time he looked at her, he was overcome with fruitless desire.

He wanted her. Always had and always will. He didn't care who stood in his way because in the end, he would have her.

Severus watched her carefully; she was completely unaware of his stares. Her back was turned to him, her eyes, he imagined, were rapidly reading the words of her textbook while her gracefully formed the words that she read. She looked heavenly and irresistibly; it was during this time that he wished he could see her face. His imagination ran wild with the idea of her biting her lip, and what his could do to ease the pain from that bite. Her eyebrows would be drawn together in annoyance as she tried to comprehend the words of their Potion's textbook.

A smirk swept across his face as he approached her.

He just had to cajole her.

"Having trouble again, Evans?"

Lily gasped, turned and glared at him. "Severus!"

The Slytherin chuckled and held up his hands in defense. "Hey, now. No need to get territorial. I'm here to make sure you understand the material. We do have our test next week, you know."

"No everyone understands it the first time, Snape."

"Oh, no. It only takes you a couple of tries."

She glared at him as he snickered.

"I'm joking, Lils. Relax."

"Git."

"Back to derogatory names, again?"

"Evil git," she giggled, scooting over to allow him to sit. "I thought you were going to see Slughorn." Lily tilted her head and rested it on his shoulder.

He exhaled sharply. "Slughorn, it seems, has gotten his appointments mixed up. I had to make a new one."

"Pity," she chirped sweetly," I sincerely thought I could get some studying down before you came."

"You could use all the help you can get." His eyes roamed over her notes.

"Severus!" she exclaimed with a slight ring of amusement. "I think all your talent is going to your head."

"Or, maybe I'm just better than you, Evans."

"Take that back!"

"No, I don't think I will." He grinned. Teasing her was such a thrill and was only kindled by the flame in her eyes.

Lily continued to hound him. "Take it back!"

Severus pulled her against him and whispered a daring 'no' into the curve of her ear.

Make me.

It was a dare.

She thought she was quick, but Severus' reflexes worked in mysterious ways. Before she had time to register it, he flipped her onto her back. Lily let out a terrified yelp that was only magnified by Severus' hovering figure.

"Lost all that Gryffindor courage, yeah?" he inquired in amusement. He adored her and the bravery associated with her house.

Lily huffed underneath him. "I still have it, you know."

"Where is it, then?"

"Severus, please."

"Using your big girl words, Evans?"

"You're acting like a child…" she mumbled as she wiggled around.

He chuckled, tugged her hair behind her ear and leaned in.

"Give up?"

"Never!"

"I'm enjoying the view, so tell me when you're ready to surrender."

"I already have," as she said the word, Lily's hand came to rest on his chest as her lips sought his.

Severus growled at her near submission; he didn't think his Lioness would submit so soon.

She's cunning, he thought as her lips moved urgently against his. They grabbed at each other; his hands combed through her hair as her fingers splayed themselves across his chest.

"What would Potter say?" he asked, capturing her bottom lip with his teeth. "Seeing you like this?"

"I wouldn't care." She moaned when his lips travelled south. "Only you can see me like this, Sev."

For Severus, it was more than enough motivation to claim her.

"Are you sure, Lily?" he asked, nervously. "Surely, someone-"

Lily stopped him before he could finish.

In shock, he opened his mouth and Lily slipped her small, pink tongue into his mouth. She drew light circles around the roof before sliding elegantly against his tongue. Shuttering slightly, she withdrew from him.

"I don't want anyone else," she confessed as she planted one last, innocent kiss upon his lips. "I want you."

Severus halted her wandering fingers and touches. "You don't know what you want."

"Yes, I do." She was insistent and pleading. "I don't want anyone else, Severus. I want you and only you. Why can't you accept that?"

"I never thought you'd reciprocate my feelings."

"Severus…" She slipped her arms around his neck. "How long?"

"Pardon?"

"How long have you known?"

"How long I've known I loved my best friend?"

Lily nodded. "Yes."

Severus gulped as she played with his hair. "Years, Lily. "he told her. "I've known for years."

"Me too," she smiled. "I love you. Ever since the day we met."

"May Salazar wake me from this dream." he breathed, his grip on her tightening.

"I assure you, this is real." She pecked him softly on the cheek.

"I should hope so, my Flame." He smirked, descended down upon her. A burst of magic enveloped them. Lily moaned into his mouth and he took the opportunity to claim her. "Mine."

She nodded, grinding herself against him.

"Always."

Even a promise like that was more than enough motivation.
