I wrote this on break between classes. I hope you like it and as always I own nothing of the world of Harry Potter.
Severus and Hermione were standing in his classrooms at Hogwarts screaming at each other. Most of the students were now used to their Charms Mistress and Potion Master screaming at each other. Two girls walked by the room giggling as they slowed down to pick up that day's latest fight. Most of the older teens just rolled their eyes and there was a bet going on in each house how long before they married each other or killed each other.
"Minerva said you need to help me with this project. I don't know why you are fighting me on this." Hermione was pacing some in her teaching robes. It had been nine years since the war had ended in the Order's favor. Severus could be still as frustrating of a man as he was when she was in school. The task was simple, she was playing on a spell that went with a potion it would take back the aging process. A wizard could live over a hundred years, this would insure they wouldn't physical age as fast.
"There are other potion masters you could work with." He was sneering at her. "Someone more qualified to make beauty potions perhaps." He said turning away from her.
"This is the potion I think will work, I want you to look over it and tell me if it will. I will brew it myself if you wish." She handed him the paper she pulled from her robes. She turned and left him standing, holding her paper mumbling under his breath.
Hermione made a point of avoiding Snape for the next few days, that man could drive her insane and sexually over the edge at the time. The first time they had a fight, she was ready to obliterate him. She hadn't been teaching a week when she asked him she could have a headache potion and he went into a twenty minute tirade that she was able to make that potion herself without needing to raid his store. She had thought if she had killed him in that moment, nobody would convict her. At the same time his rants made her desire him; his voice, the way he looked at her and the path his fingers went slowly over the vials of potions when he eventually gave in. She imagined his fingers on her body moving that slowly, caressing each part of her body. She shivered when she left his lab and ran into her room, her fingers were no substitute for the actual thing. Hermione was sure that would never take place, he had no desire for her.
After two years they were still fighting constantly and he was still turning her on. It wasn't as if she waited around for him to see her. She had dated Draco for a few years after the war and when she started working they were on again, off again. He was still trying to find the right witch and Hermione knew she wasn't it. He would still call her if he needed a date for a Ministry function, but they both agreed they were good friends. She tried dating Ron a few times, Harry and Ginny had set her up with a few guys from his line of work as an Auror. Her love life was alive but the bad part was she knew Severus was too. Hermione was sure Minerva was losing it in her late years, she had placed Hermione's rooms next to Severus and for some reason between those rooms they had never heard of insulation. Hermione knew Severus knew what a silencing charm, but for some reason never put them up when he was seeing a witch. Many nights when he was visiting a witch, she would be kept up hearing yelling and groaning. She wished he would find quieter witches.
After three days she headed back to his classroom after classes that day, she wondered if he had looked over the potion she had created. She knocked and waited for him to open the door, she heard him call out, but had no idea what he said. She pushed open the door and walked inside.
"Severus?" Hermione cried out. She waited and sighed, leave it to that man to keep her waiting.
"Hermione." Severus walked out of the back after about five minutes. "Now you just walk into my rooms?"
"I knocked and thought I heard you call me in, I have been standing here for five minutes." Hermione was getting crossed with him.
"You see Hermione, I unlike yourself have things to do after class and cannot wait around for you to appear." He was leaning on his desk leering at her.
Hermione was thinking of ways to kill him at this point. "Have you looked over the potion I created?"
"Yes and I dare say stick with charms."
"My minor was in potions or have you forgotten? That potion will work."
"No, it won't, not with the charm you have created." He moved in closer to her.
"Severus I have been working on this for months, I know it will work." Her voice was raising some.
"As much as I would love to continue in our foreplay, I do have a witch I must prepare for."
Hermione rolled her eyes in frustration. "This isn't foreplay and for the sake of Merlin learn a silencing charm. I am so tired of hearing whoever the witch is this week howl like a banshee."
His eyebrow crocked up. "My dear are you jealous?"
"No, I'm tired of hearing your love life. I make sure my rooms have charms around them not to bother you, I wish you would do the same."
"The witch I am waiting for is not that kind of a witch and while we are on the subject I say nothing when you and my godson are moaning in the hallway. I can hear that in my library, it is distracting while trying to read."
"Draco and I haven't moaned in the hallway in over a year." She wanted to stick her tongue out at him. "What kind of witch is coming?"
"Always so nosy, I can see why you couldn't make it work with Draco and the line of men after him." Hermione's face was redder than Ron hair at this point. "I have a student coming in, she will be doing her apprenticeship under me."
"I see you can let a strange witch do that, but when I was studying you refused."
"You have never asked to be under me or I would have complied years ago." He was standing over her now, she could feel his breath near her face.
"I meant the apprenticeship." She took a small step back.
"I wager you were." He was looking down at her intently. "If you must know the witch that will be working under me has no other place to work."
"Why?"
"Good lord women, are you always this way. I feel for your lovers." He turned around and was heading to his labs. "Come on." She followed him into his labs as he held out her paper to her. "The ingredients are wrong, you cannot add fly wings and dragon's blood in the same potion. I taught this in the second year, I recognize you were preoccupied with being a know-it-all than to listen to me."
"You stated we couldn't because the potion would explode and look it didn't, you were wrong." Hermione pulled out a blue vial from her robes.
"Blasted women, why did you ask me to see over this if you went ahead and created the potion." He threw the paper at her.
"Because, you ass, I need a potion expert to look over it." Her voice was too loud.
"I did and you won't listen. I assure you if you test that on anybody you will cause terrible results." He was screaming at her.
"Then help me make a better potion."
"I am not in the habit of producing beauty products." He sneered down at her.
"I don't know why I thought you would help me with this you are such a bastard." Hermione bent over and plucked up the paper off the floor.
"You will forever be a chit." Severus stormed by her, knocking the potion out of her hand.
"Severus!" Hermione screamed as she tried and catch it before it fell on the ground. Severus turned to hear the glass break and the room to fill up with a blue fog. He took hold of her to move her out of the lab but the blue smoke engulfed them as they both passed out on the floor.
