Lust Potion

Not one of these characters belongs to me.

Lily Evans, pale, petite and beautiful, entered the Great Hall that morning feeling as if she hadn’t had a moment’s sleep. Truth be told, she had hardly more than that. The idiot boys in her year had been cheering and screaming about something. She had heard cries of ‘finally’ and other various words beginning with ‘f’ all the way across Gryffindor Tower. The four had evidently been celebrating, however, for what she had no idea.

As the girl forced down a piece of toast the four seated themselves uncomfortably close to her, each looking more exhausted than any of the many students. What had the idiots been up to? She wondered, then decided she simply couldn’t be bothered with it. Whatever it was it wasn’t important to her, however, she thought, it was just as likely to be incredibly dangerous. Maybe if they get themselves hurt they’ll finally realize how stupid they are.

Lily glared at the four teenaged boys. The one nearest to her had a disgusting habit of ruffling his hair every other minute or so, glancing at Lily in what he probably considered stealth.

The four were chatting excitedly, but not loudly enough for her to overhear. She shook her head slightly, wondering why she even bothered to take any notice of the boys.

None of her friends had arrived at breakfast yet. She gazed listlessly at the doors to the Great Hall, hoping that Severus would arrive soon. She hadn’t been able to talk to him since the Hallowe’en feast, three days ago, and she felt like she was being ignored.

Finally, as she picked at the last of her eggs, Severus arrived, and seemed to be heading in her direction. “Sev!” She cried happily, causing the four boys to turn and glare at the approaching friend in disgust. Severus forced himself between Lily and the girl on her right. “I’ve missed you so much.” She said sadly, turning to look him in the eye.

“Terribly sorry,” He replied, though he didn’t seem too upset. “I’ve missed you as well. I’ve just had more work to do lately.” He sighed heavily and rolled his eyes. “Remember Slughorn’s detention on Hallowe’en, right after the feast? He’s given me an essay on how quickly potions turn poison when you don’t stop chatting up the pretty girl to your left. Ten rolls of parchment! That ass.”

“Sev, don’t swear.” Lily said seriously. “He’s your teacher! Besides, he would probably rather be the one chatting up the pretty girl to your left.”

Severus smiled slightly. “But anyway, I just want you to meet me tonight in my dormitory, all the others are going to be out, and I wish to talk to you privately, for once.” He lowered his voice, “Password’s basilisk.”

Lily nodded, and reached for her juice. “Evans, no!” Shouted one of the idiot boys. “ That greasy git slipped something into it!”

“Shut up, Potter, if I were to slip anything poisonous into a drink it would be yours.” Severus really wasn’t trying this early in the morning. “Ignore them, Lily, they’re just trying to cause more trouble.”

Lily nodded again, agreeing with Severus and downing the last of her milk. It tasted a little off, but she hadn’t taken a drink since she finished her toast, and it had since grown very warm.
Lily’s day passed by slowly, but for the few classes she had with her ‘Sev’. For some reason she felt much more excitable than usual. At one point Severus accidentally brushed against her tits, and while he apologized profusely, she could think of nothing more than his fingers squeezing her small tits, and tugging on her hard nipples.

Despite the thickness of her robes and cloak during their join Care of Magical Creatures class, the points of her nipples were visible through her clothes. Her knickers felt constantly damp, and she kept wishing she couldn’t sneak off and get herself off. By the end of the day she wanted to jump on any cock that was willing.

During her very last class of the day, double potions, it took all her mental strength not to through herself to her knees and force Severus’s cock into her mouth. But she remembered her promise to meet him in his dormitory.

These thoughts bothered Lily on another level. Her mind constantly streamed the thought, “he’s your friend” whenever she thought these things.

“All right,” Called Slughorn. “Clear up your things and sit back for the last ten minutes so your potions can simmer. Chat amongst yourselves.” Lily cleared up quickly, then sat beside Severus.

She could hardly control herself anymore. Her knickers were soaked from the days thoughts, and she ached for a touch. She snuggled up again her friend. “Sev?” She asked, placing her hand on his thigh near his cock. He stared at her silently. “Please”

“Stop being an idiot Lily.” He snarled, and pulled away from her. Lily felt shocked, but decided it was for the best. Tonight she could have what she wanted.

Severus grinned as the bell rang, and he dashed out of the classroom to the Great Hall for supper. He sat at his own house table this time, chatting with his friends, avoiding Lily’s eye. He had to pretend he was ashamed of her for now.


The first half of the potion he had given her worked perfectly, it was to build a strong, sexual craving throughout the day, until it’s partner would be fed to the unwitting victim in the evening. And soon as the second touched her lips, it would turn her into a useless fuck toy.

However, unlike other potions she would not only want his dick, she would want any she could get, but Severus accepted that. He knew he could humiliate her, and she deserved it. The little slut was getting closer to the four boys as time went on, he could see it, regardless of how much the whore denied it.

“Look at that Evans whore.” Said a Slytherin boy, laughing heartily. Severus looked up to see Lily sitting across the hall at the Gryffindor table, one of her arms under the table, jerking slightly. Her face was flushed and she seemed to be whimpering.

Severus felt his cock harden as he watched his friend rubbing her cunt under the table. He couldn’t wait until she would be sucking the dicks of boys for supper. He wondered it he could make her eat out her friends as well. He’d have to see how strong the potion was.

If it was as strong as her intended it to be, she would obey him, but her normal emotions would still be there. If he wanted to, he could even have her fuck their fat potions teacher. He probably would.

And the best part of all was that the potion lasted until the very rare and tricky antidote was fed to the drinker. They would never know what had been given to them.

“Isn’t she friends with you, Severus?” Asked the same boy, a seventh year.

“I’d hardly call her a friend,” He laughed coldly. “She just a little slut. The mudblood brought me along with her parents on vacation over the summer. Yeah, I would have said no immediately, but I decided it was better than staying with my muggle father.” The boys around him still looked disgusted. “Oh, I know, I know, but have you seen muggle swimwear? I could almost see the little slut’s twat! And that was before she took the swimsuit off so she wouldn’t get ‘tan lines’!” He boys were now laughing, staring at him enviously. Little did they know his words were less reality and more a dream. Yes he had gone on vacation with Lily’s family, but she had only untied her top, while laying on her stomach. “She asked me to put lotion on her back so the sun wouldn’t burn her.” He paused, smirking. “So I came on her back, and she let me rub it into her ass.”

“She isn’t good for much more than her mouth or cunt, is she?” They laughed, watching the girl getting herself off. Finally she came, just as the pudding was served.

Lily rushed along the dungeon corridor to the Slytherin common room. Just as she was about to mutter the password, she heard someone behind her. “Who’s there?” She demanded.

James Potter appeared from nowhere, surrounded by his friends. Lily had to admit, aside from Sirius, his friends weren’t as awful as him. Remus Lupin always seemed like he was being dragged along with their schemes, and little Peter Pettigrew seemed to follow only because he felt lucky to be in their midst. The ringleaders were still insufferably fools, however. “Why do you trust him, Evans? He put something in your drink. You were masturbating during supper; he probably slipped some sort of fucking potion into your drink. He’s going to rape you.”

The much smaller girl drew herself to her full height and glared at the boys. “I’d much rather suck his cock than yours, Potter! Some of us women have standards, not all of us suck disease ridden jock dick.”

“See what I mean? Since when do you speak like that?” But the girl ignored him, whispered the word basilisk as softly as possibly, and slipped into the common room. The boys didn’t have time to follow.

She strode quickly through the common room, her arms crossed in a way that the Gryffindor crest on her chest wasn’t visible, and ran down the path to the boys dormitories, into the fifth room.

Sure enough, Severus sat alone on his large, four poster bed. “Tea, Lily?” He offered politely.

“Thank you.” She gulped the tea quickly, and suddenly her body felt explosive. “What did you put in this?” She cried, or at least she attempted to. Nothing came out but a soft moan.

“Ah, my sweet little filthy mudblood whore,” Severus said cheerfully. “You’re completely mine now. Well, you will do as I say, at the very least. By the end of tonight your little pussy if going to be so full of cum you won’t be able to stand.

“You see, you can’t help but obey me. From now on, whenever I or anyone else calls you mudblood, or anything else insulting, your little cunt will become soaked, and you’ll instantly need to cum, no matter where you are, slut.”

It was a wicked, dark sort of magic. Her pussy, already soaked, now felt slick and hot. “Please, Sev…” She suddenly begged.

“Good, good, that’s right.” He whispered, as she quickly pulled off her own robes. “Not yet.” He snarled, as she reached back to unhook her bra. “Get on your knees, bitch, I want you to clean my cock with that little mouth of yours.”

Severus stripped quickly, his cock had been straining against his underwear for the last ten minutes, waiting for the girls arrival. It was sure to be pleased.

It was larger than on would have suspected on such a thin boy, but maybe it appeared so because of its thinness. Lily obediently fell to her knees and crawled forward, grabbing his cock tightly in her fist, stroking it gently. She carefully began to lick the head with her small pink tongue. Above her Severus was moaning his delight.

He grabbed the young girls head, forcing his cock into her mouth. She gagged and spluttered, but he took no notice, and fucked her mouth, pulling roughing on her gleaming, red hair. All too soon his cum shot into her stomach, and he pulled away, glaring down at his prey.

She had been rubbing her pussy the whole time, a large damp spot had appeared in her knickers. “Stand up, cunt.” He ordered, and the girl stood, stumbling slightly, her hand still shoved into her knickers. “You want it so much, don’t you.” She nodded.

Severus struck Lily as roughly as he could. “What’s that, bitch?”

Lily shuddered, her mind still wanted to resist this, but her body couldn’t stop itself. She wanted his dick to fill her, she wanted any dick to fill her, she didn’t care if it was attached to the headmaster himself, or even Filch, the hideous caretaker. “Yes…Master Severus. I want you, I want you to fuck me, please, please fuck me, Master Severus,” Lily begged. Severus could feel his cock hardening again.

“Have you sucked dick before tonight, Lily? You have to tell me the truth, or I’ll shove all nine inches of this into your little ass hole, and I won’t remember to lube it.”

Lily quivered, her pussy almost dripping. Even that made her pussy pulse with excitement. This potion was mad! She had to stop, she couldn’t do this. Nononononono. She had known Severus since she was ten! She couldn’t fuck him! She did not just suck his dick while rubbing her clit, she couldn’t have. This was horrible, some sort of nightmare. Why could he not have been nicer and just imperius’d her?

“Mudblood?” Severus demanded. She stood gawking at him, rubbing her pussy and groping one of her tits. She made him so hard, but he couldn’t be gentle. Gentleness weakened the potion. He shoved her to her knees and began stroking his cock as hard and fast as he could, until finally he came on his best friend’s face. She eagerly attempted to lick it from her lips.

“It tastes so good, Master Severus, you make me so wet. Please fuck me.”

“Mudblood, answer my question. Have you ever sucked dick before tonight?”

“No, Master Severus. I haven’t touched a cock before, Master, please fill my pussy up with you dick, and your cum, please fuck me, please, please, please!” The normal Lily had weakened, now her mind was giving in completely to the potion. She wanted his dick. He had been her friend for five amazing years, she couldn’t think of anything hotter than him stealing her virginity.

“Take off your bra.” She obeyed. Her tits were small and soft, with round, hard pink nipples. Severus reached forward and roughly groped one, and began nibbling on its twin’s nipple. Lilly whimpered and moaned. She had never made herself this wet.

“Please fuck me, please!”

Severus forced her onto her back, and pulled off her soaked knickers, gazing at her smooth pussy. “Why did you shave it, if you don’t fuck, whore?” He asked, rubbing her tiny clit.

“I…I…oh…Justine White!” She gasped weakly between moans. Severus stopped, forcing her hands behind her head.

“What about the head girl, Lily?”

“She likes to lick my pussy!” She squealed, hoping her would stick his cock into her soon. “She…she forced me into it first, tied me down and did it…but then I liked it. I came so hard. She promised to do it again, if I got rid of the hairs.”

Severus became harder, if it were possible, at that statement. “You really are a disgusting whore.” But he didn’t fault her. He had almost imagined she had been letting Potter lick it. “Was it like this?”

Severus flicked her tongue over her clit, and Lily cried out.

“No, Sev! Please, more!” She whimpered and he began to suck on the tiny little sphere of flesh, and shoved two fingers into her, trusting in and out of her tight, virgin cunt. She felt like she was melting, like her very core and turned into sweet, sticky, musky liquids.

She screamed as she came into his mouth, her pussy soaked with cum, spit and sweat. “Because of the potion, it won’t hurt Lily.” Severus promised, rubbing his dick against her tired clit. “But the potion doesn’t promise you can’t get pregnant.”

A flood of horror flooded her face. “But I’m still going to cum in here, and so will everyone else I make you fuck. Oh yes, I’ll have many fuck you.” He added, seeing her grow more frightened. “By the time you’ve graduated, your pussy will be so loose that oaf Hagrid could fist you, and you wouldn’t even feel it!”

Even with the potion meddling with her brains and logic, she started to cry. “Please, I want my pussy to stay pretty.” She begged.

“Well, you’re lucky then. This little cunt-“ He placed the tip of his cock to the small, virgin hole,”-will stay tight as long as you want every cock that fucks you.” He shoved his dick in and violently and he could manage, trusting roughly and evenly. “But I can’t promise that that oafs cock won’t fill it.”

Lily sobbed, but her body felt amazing. She couldn’t stay sad, she wanted it, she wanted it all. Hagrid’s dick would do if she could get it. She felt her pussy grow hotter, imagining how huge his cock would be, imagining the huge load of cum filling her twat.

Severus continued fucking her, squeezing her small tits, and licking her nipples. She wouldn’t have cared if she died, though, she supposed it would be awkward, for Severus, at least.

“Ah! Fuck, Master Sev! Cum in me, cum in me, please! Please!” She yelled, loader than she could have imagined. She writhed and moaned, rocking her hips, increasing the friction, begging for more.

When she came she cried out again, loader still, her small, not so virgin pussy tightened around Severus’s cock, and he couldn’t bear it any more. He shot off inside her, grinning broadly.

“What a good whore.” Severus said cheerfully, dripping in sweat. Maybe it was time for a shower. “Now, Lily, Lily, stop being a lazy Mudblood.”

She sat up quickly. “I want you to go to the staff washroom, the one of the Seventh floor. Don’t whimper like that bitch, and no, you may not put your clothes on. Should anyone stop you on the way, let them do what the want to you. Let them lick your pussy, fuck your ass, or cum in any hole. Should a girl stop you, get her off, make her scream like I made you.

“Finally, in the bathroom you are to rub yourself and moan and cry until some poor man comes along for a piss, as soon as he’s done start sucking his dick. Offer your pussy, tits or ass for his dick. GO!”

Lily flushed furiously, and ran through the common room, feeling beyond lucky that no one was there, but she had to admit, even her real mind was loving this. She ran down the long corridors, not even trying to cover her tits, her pussy feeling hot and excited, and not only because of what had just happened.

This is my first fanfic in years so I apologize for the awkwardness that comes from using someone else’s characters. I love Lily/Severus, and it’s partly Canon…except not. I fully recognize that it was one sided in the novels, nor do I think Severus got much more than a friendly kiss from Lily. I don’t believe he would have used her in this way, but I DO believe he’d poison James’s morning pumpkin juice.
