A/N: Another story I did awhile ago, but never did anything with so I am posting now before I forget. This one has several of its chapters mostly completed, but they need edited. I feel okay posting this knowing how far along this story has already come so I know it won't take much, just whenever I feel like editing the chapters, I will post the next one.

*Also, this chapter and story contains some explicit sexual content. Holding back for this story would leave out too much and lose the meaning. You've been forwarned. And by explicit-I am not giving an anatomy lesson.

Edit: Misspelled two words on accident. It's potpourri and preferential. Anyway, fixed now. I'm surprised I did not catch those earlier.


Love Potion No. 5

Chapter One: Obsession

Sirius Black took a potion from a cabinet. "That looks nice. It's perfect. Knew it would be."

"A love potion? Who's it for?" Peter Pettigrew asked.

"A certain red-head."

"What red-head?"

"The lovely one of our year, Miss Lily Evans."

"I thought James fancied her?"

"It's for James to give, not me, you idiot! She's starting to fall for him anyway. We will help her get there."

"It won't make her love him though, right?" Peter said.

"Don't try and use logic, Wormtail. You suck at it. She already likes him. Just a little bit and she will be all over him."

"Does Prongs know?" Peter asked, a devilish look in his eyes, likely hoping it would be a secret.

"Well, I haven't told him yet. I was going to help them get to where he wants with Lily-in bed. Just a little bit to make her wild for him and him for her."

Peter grinned excitedly. "You mean getting them to have sex?"

"Yes, you dimwit. They like each other. This will get them in the mood. What could go wrong?"

Sirius poured some of the potion into two bottles of butterbeer. "We'll swap them out with the one's Slughorn always gives out with breakfast for his last Slug Club meeting before we part for the holidays. James and Lily will be there. He always picks them to do favours. They will hand it to each other, drink up and go wild."

"Yes, Prongs will love to be with Lily." Peter sneered. "You think he might be mad at us if he finds out?"

"Nah, this is Prongs. He'll thank me. I perfected it once, the amortencia, but no worries, this one will be safe and effective."

"How do you know?"

"Because it's Snivellus's potion."

"Wonder what Snivellus is doing with a love potion?" Peter snickered. "Think he was trying to shag a girl?"

"It was for our assignment, dunderhead." Sirius huffed. "Look, as long as James is the giver of the potion, it does not matter who brewed it so there is no worries about Snivy getting in the way. Slughorn gives preferential treatment to Lily and to Prongs. Snivy is a wannabe Death Eater. Slughorn is not into them." Sirius gathered the bottles. "Come on, it's free period. We have to be fast."

Sirius and Peter snuck into the room where Slughorn held his meetings. "Be my lookout, wormtail." Sirius removed the bottle with Lily's name and the one with James's name. He replaced them with the amortencia laced butterbeers. As Sirius put James's name on his bottle, Peter whistled.

"Someone's coming! Hurry up!"

They got under the cloak and hurried away.

The following morning, Slughorn came in the room and as he sat down, he knocked a few bottles over and name tags off of them. He picked them up and randomly put names back, assuming it did not matter anyway. He only put names so make sure everyone got one. As he put a name on the last bottle that had fallen over, his club members entered.

Peter and Sirius waited outside of the doorway for Slughorn to hand out the beers for his club. James kept looking over at Lily. Sirius nudged Peter to point out that Lily stole James a couple glances back. Sirius hoped James and Lily would soon be infatuated with one another and they would end up in bed. James wanted her. He deserved her. They deserved each other. They were stag and doe. They were perfect for each other and he just wanted to help them get together finally.

"He'll get his time with her soon. She is totally into him." Sirius paused. "Come on, let's go before someone sees us." The two of them hurried away.

"Okay, Ms. Evans, why don't you help hand out my drinks?"

Lily heard her name and got up to help her professor hand out the drinks.

"One more person." Slughorn looked around the room. "How about um, Mr. Snape? Help out with the drinks."

Severus looked up. Great. He thought. He set his book down. "Fine." He got up and went to the front of the room. Lily and Severus ignored each other and took a handful of drinks and began to hand them out.

Lily put the one with James's name in front of him. He smiled at her. She gave him a small smile back and handed a Ravenclaw next to him his drink. Lily moved to the other side and handed some of the Slytherins their bottles.

"I don't want this, the mudblood touched it."

Lily saw Severus look up when the word was mentioned, but he turned away and handed someone a bottle. She ignored the word as well and handed the boys their bottles. She set Severus's bottle on his desk and moved on without glancing at him. Severus handed a Hufflepuff her bottle and as he turned around, James took his foot and nearly tripped Severus.

"Quite clumsy, aren't you, Snivellus." James snapped quietly. "Watch your step. Wouldn't want anyone to slip on the grease you'd leave when you hit the ground."

Severus gave James a murderous glare. "You watch it, Potter. You'll pay one day." He hissed quietly.

Severus turned and set a bottle at Lily's place as a couple people sniggered at his near fall. Lily sat back down and Severus did not see her smile. He guessed Lily must have missed the incident or he was certain she would be laughing too. Severus moved back to his seat beside a girl from Hufflepuff who was talking to another girl in Ravenclaw.

"Bottoms up." Slughorn said and sat back down. Everyone moved around the room to get refreshments.

Lily started to drink her bottle and noticed something odd. It tasted fine, but it smelled different. It smelled like peppermint and morning dew on the grass and the riverbank back home. She felt a little homesick. She smelled a boiling cauldron and some scent she could not put her finger on. Oddly enough, she could smell the Hogwarts Library with its slight potpourri and ink aroma. It smelled like someone familiar, but she could not place a finger on that either.

Severus took his bottle and took a sip and noticed it was odd smelling. It smelled like cinnamon, the dew that came from the morning grass, the riverbank back home and it had a flowery smell to it. There was a strange smell in it he could not explain, but sensing it made him crazy. He could sense the smell of the school's libary as well. The potpourri and ink that comforted him. He sighed. It smelled like Lily. He really was losing it. They were not friends anymore. Any day now she would agree to date James and they would be together. He hoped secretly that when he became a Death Eater, she would see how good it was and how he would protect her and she would see how powerful and strong he could be. He was not just some poor, greasy-haired git who was constantly bullied and studied all the time. He could be strong and manly. He could be better than James. It was all a dream though. He had a snowballs chance in hell of being with her. She would not want him when she had someone has perfect and wonderful as James Potter fancying her? Why would she pick him over someone as rich, handsome, smart, athletic and popular as Potter?

He took another few sips and felt an odd sensation burning through his body. Part of him began to panic. It tasted fine, but maybe it was poisoned? No, that couldn't be it. He would not feel so well if he had and he felt oddly wonderful. His heart began to pound and his body pulsated strangely.

"Everyone off the carriages if you are leaving! Have a good holiday!" Slughorn called out.

Lily suddenly felt odd. Was her drink poisoned? No, that could not be it when she felt so oddly wonderful. She felt her heart pounding in her chest. Her body pulsated bizarrely. What was wrong with her? She looked around the room, desperate to find someone, some person. Her eye caught Severus and her body throbbed with infatuation. She needed him. It was him she loved, she knew it.

Severus felt a powerfully odd feeling. He caught Lily's glaring eyes and though she always made his heart skip a beat, it was ready to burst out of his chest. He tried to calm himself, control himself, but something was off. He had to have her. He had to talk to her. He loved her so deeply. They exited the room and Severus desired to catch her. To his surprise, she was waiting for him in the hallway.

0o0o0o

Lily grabbed Severus by his robes, which startled him, and pulled him into an empty hallway. "I think I'm love with you." Her heart raced so fast she thought it would explode.

"I always loved you, but I am madly so right now. I want to hold you and never let you go, ever."

"Then don't."

She pulled him into a closet and kissed his lips. Hot damn! Severus thought. He had never kissed anyone before and they both giggled in nervousness as they practiced. He just wanted to grab her and never let her go. She felt the same. They had no idea what was going on at all. All they knew was they were in love somehow. After ten minutes, they forced themselves to stop touching and kissing each other.

"I am going to be late." Lily said.

"For what? Are you leaving? Please don't love, I mean, leave, leave me here alone. I need you."

"No. I'm head girl, I must stay here at school. I must leave soon though. I have to go do my round." She kissed him again. "But I dont want to leave. I love you too much."

They gave each other one last, long kiss before prying themselves apart unhappily.

Lily could only think of Severus the rest of the day. She could hardly eat lunch. She doodled on her parchment and wrote out her obsessed love for him.

Severus only thought of Lily and could not concentrate on his book. He felt like he was going to go crazy without her. He needed her and he had no idea why.

"Are you okay?" Avery asked Severus at the same time Remus asked Lily in their common rooms.

"Wonderful." They both replied in their obsessed thoughts of the other.

Lily sighed to herself.

"Are you in love?" Remus asked.

"Yes. I am in love with him. I need him."

"You need him?"

"Yes. I can't stand it."

"Have you lost your mind?"

"Maybe. Love makes you crazy, I guess." She sighed and felt her heart flutter. "I can't do any work. I need to find him. Yes, I must see him." She got up and left the tower, desperate for Severus.

Severus looked at Avery, who was looking at him as if he had lost his marbles. "What's the matter, Snape? You act like you are in love?"

"I think I love her. Yes, I do love her. I need her."

"Please. You don't love her. It's just your hormones. Just go shag her. You'll feel better afterwards. If you can't, just take care of it yourself. I'll lend you my Witch's House magazine if you want."

Severus looked at Avery confused and bit back the lashing words that he thought at the moment. He did not care about Avery. He did love Lily. He loved her to bits. He had to have her, had to love her all he could. He would burst if he did not get to love her more. He left the bowels of the castle to search for Lily.

Finally, that evening before dinner, Severus snagged Lily in the hallway and into an empty classroom, kissing her with fervour. She gave equal fervour back. Severus grabbed her buttocks hard, pulled her close to him and he never wanted to remove his hands from her again. He never knew he could have such bravado. She did not do anything and he in turn found his buttocks being grabbed. Lily felt like she was going mad. Why did she love him so much? She had no idea, but she did and that was all she knew.

Severus and Lily ended up making out until dinner. After dinner, they meet privately in the courtyard and it seemed all hell broke loss between them after one simple kiss on the lips. They lost control, completely infatuated with the other. Severus grabbed her robes at the shoulder blades and she moaned as they kissed. Lily gripped his robes at the back and moved as close to him as she could. She wanted him so bad and she had no clue what suddenly brought that on. She groped him and he moaned and clutched her breasts. Lily moaned and pulled him to her until she was pressed against him. She felt his hands grab her by her haunches through her robes. They were losing all self control and were happy about it.

"Let's go to the tower. The others are all home. We'd be alone."

"Yes, please."

"Race you." Lily said, not losing her playful self even with the haze of the fanatic love that clouded her thoughts. They entered the common room. It was empty. She took him up to the dorm and shut the door.

"I thought you couldn't have boys in your dorm?"

"If I invite them in personally, then yes they can. Boys can't enter the room on their own. Old-fashioned, yes, but honestly, probably safer. I invited you, brought you here so you can be in my dorm."

He pulled her to the wall and they made out. She started to lift his robes. His body throbbed with desire for her. They pulled off each others robes and got into her bed. They were both uneasy as they laid there in their undergarments, but the haze of the infatuation seemed to help them loosen up quickly. They wanted each other too much to let nerves stop them.

Severus pressed his pelvis to her. She moaned with pleasure. Lily had never felt sexual desire so strong until that moment. "Make love to me, Sev. Please, just make love to me."

He moaned as she thrust herself against him, causing his pelvis to pulsate and ache miserably. He never felt a sexual desire like this before and never so intense and never so strong. "I need to love you. Let me make love to you, Lily. Make love to me. Please."

"I will. I will. Just love me back with all you've got." They undressed and she immediately wrapped her leg around him, pressing her pelvis hard against him, desperate for him to stop her desire once and for all. He did not hesitate to get inside her either, the desires he felt so intense he thought he might be going insane.

"Ow." She cried and winced in pain.

"What's wrong?" He asked, looking at her.

"Nothing, it just hurts."

He removed himself with a painful cringe, having barely released any tension. She was bleeding a little. He felt bad now.

"I'm okay. Just give it a minute. It's my first time."

"Mine too." He admitted. He groped her bosom as he tried to control his throbbing pelvis while he waited for her to feel ready to continue. He wanted to complete this and release the building tension in his body.

"Then we'll figure it out together." She sighed and readjusted her position back to him. They took it slower the second time.

They spent the next two hours together, learning what pleased the other and stroking each other in their affection. Even with the obsession, they worked to try and make the other feel loved and worshiped and happy while they made love. Lily felt herself breathing hard and panting a little. She pressed her hands against his shoulders, moaning with satisfaction. Her head felt like a whirlwind, swirling between a crazed obsession for him and a sick to her stomach love that had her over the moon and soaring through the stars of her confused mind, back to the man in front of her. It had to be the strangest feeling she had ever experienced, yet it was an euphoric feeling at the same time. She felt herself pressing harder into him. He pushed his own pelvis hard back into her, making her feel like she was floating. No one else but him mattered right now. She was in an ectasy she never felt before. Never had she been so happy.

"Are you okay?" He asked, still a bit concerned about her since he had made her bleed before.

"Amazing." She said with a satisfied moan. "Keep going. Harder. Hard as you can."

He did and she groaned. "Oh yes, yes, right there. Oh, god, oh, I love you so much." She bucked her own hips into him over and over, desperate to get all she could from him in her own obsession. It was if nothing was enough, that she could not get enough from him and that maybe she was not doing enough to keep him pleased. She had to keep him and for some reason that she could not normally fathom, she felt this would do it. It was not like her. She never would have considered sleeping with some guy as a way to keep them around, but her fixation changed that idea. Outside of the potion, she never would have done it because it was a bad idea more often than not.

He moaned with pleasure as she bucked him. "Um, Lily. Lily. Please don't stop." He held onto her shoulders. "God, I love you. How I love thee. Let me count the ways."

Lily laughed at his teasing. "This way works just fine, Sev. It's enough. I want to love you like this forever."

"Then we can stay like this forever if you want." They rolled over until he was on top of her. Severus drew hard into her, pressing his pelvis down onto hers, wanting all he could get and wanting to please her in his actions. His crazy, obsessed love for her made him feel like he had lost all control and he felt desperate to please her, to keep her with him and felt this would do it and prove he could make her happy. He felt so infatuated with her at that moment he felt he was going insane. He loved her in a way that confused him, that felt off, but yet, he knew he loved her with his true heart, his real soul. He always had. His mind felt like a bewildered whirlwind at the moment. He felt sick to his stomach with love. He felt like he was soaring through the stars with her and no one else mattered anyway, just her. Something about this with her made him feel alive. He never felt this feeling before, never knew how much different he could feel as a result of doing this with Lily.

Lily felt her lower lip tremble because she wished they could be like this forever. She was so happy in this state of mind. Everything was right in the world at this moment. She swallowed back the tears that threatened to fall and the large lump that caught her voice. Instead of voicing her pleasure to him, she burst into tears.

"What's wrong, my beautiful flower?"

"Nothing. This is just so great, I just, I know that, I know that we can't stay like this forever."

"We can stay like this for a long while. We are alone for the break."

Lily laughed and sniffed. She gave him a nod. "Yes, we are fine for now. I just, I don't want this moment to end."

"Me either."

"We'll just have to make it good so it will carry on. The memory of this night. Our first night."

Severus took his hand and ran it through her hair, stroking it lovingly. She smiled as he did this and looked deep into his obsidian coloured eyes and suddenly felt a strange feeling in the pit of her stomach, the feeling of butterflies fluttering around that were suddenly released from a cage. Severus felt it too as he looked deep into her emerald coloured eyes, but part of him always felt that sick, butterfly feeling in the pit of his stomach when he was around her. Lily took her hand and ran it through his black hair. To her surprise, it was smooth and did not make her hand feel greasy at all. Everything about what they were doing felt right. Everything. She let out a contented sigh. For that one strange moment, it was as if the obsession was gone and had been replaced with something else genuine that neither would understand until later. The obsession came right back as soon as they tore their gazes away from each other.

At some point in the middle of the night, they grew tired and laid beside each other on the bed, not wanting to leave the other's side. Neither said much because there was nothing to really say at that time and they were exhausted.

"Night, Lily. I love you." He said, his heart still racing.

"Night, Sev, my love." She said, still feeling a weird obsession for him, yet as she said those last three words, she did not feel such an obsession. It was as if she meant them. At that moment, she certainly meant every word that came out whether it was true or not.

Lily curled up against him, her buttocks at his abdomen. Severus curled up to her and put his arm over her as she wrapped the covers tight around them. Life was beautiful for that brief instant.

0o0o0o

Lily felt the sun in her eyes as she started to wake up and groaned, shielding her eyes. Her head felt like it was in a vice. She tried to remember what happened last night, but at the moment her mind was a blur. She only remembered drinking a butterbeer. There was no way she was hung over. Lily recalled the butterbeer smelling a little off now. It had smelled like, like...She bolted up as the realization hit her.

"Amortencia!" She gasped. "Oh my god! There was love potion in it!"

She felt cold as the covers slid off of her and looked down. She was naked to her shock. Why am I naked? Did I take something with it and lose my mind for a moment? Lily looked over and saw a dark, greasy looking head of hair. Someone was in her bed; some young man was asleep beside her in her bed. She gasped and took a few deep breaths as panic hit her in the gut. It looked like,

"Oh no, no, no, it was not him. Not him. Please don't be Severus." She thought audibly. She leaned over and looked at the young man's face and gasped in dismay. It was indeed Severus. Had he given her a love potion? For some reason she doubted that. He was not the type to be so dishonest and he considered love potion dishonest and stupid. She knew that. He had told her that much and was quite serious. Besides, She and Severus were not even speaking at the moment. Severus interested in her? How absurd! "Of course," she thought, "if he was in bed with me and he did not give me the potion, then that meant, someone had given him the potion too. He wouldn't have come in here otherwise. He hated the other Gryffindors. Why else would he even consider going to bed with a mudblood?"

She panicked. He was sound asleep in her bed, beside her. If she was butt naked, he probably was too. She lifted the sheets and quilt and peeked under them. She saw his bare back and her eyes landed on his buttocks. He was naked too. "Oh shit." He had a nice bottom. "No, stop, don't think about that." This whole situation freaked her out. The idea that they would have-"Oh, dear god, no." No. She had. She had slept with him. They had slept together. They must have. The love potion had caused them to do the most intimate thing possible. The memories of the day before came flooding into her mind, cascading with horror at what she had done. They had made love and they had done it more than once. They had done it for hours.

"Dammit, I had a roll in the hay with Severus for several hours and worst of all, I really liked it." She thought to herself. "No, I didn't just like it, I loved it. It was amazing. We enjoyed it, every minute of it and every inch of the other. I touched him, all over. I let him touch me, everywhere. Oh, dear god, I did it all with him. Dammit! Dammit! Dammit!"

Severus stirred and she covered herself quickly as he began to arouse next to her. Of course, she had no idea why she even bothered to cover herself. She had nothing to hide. "It's not like he hasn't seen me in the buff before" she thought to herself and cringed in surprise at the reality of their situation. How they got the potions, why the potion was in their bottles and why they ended up sleeping together half the evening and night as a result was something she did not understand. What she did know was that they were in deep sludge as a result of this night together. After a night like that, there was no way she could forget it. They had bonded so intimately, she felt a deep attachment to him she certainly did not feel at the same time the day before.

"What have I done?" She asked very quietly to herself.
