A/N: Sorry I died for a bit.
The beginning of Flora's last term had given her hope, but she would have to find a way to prevent the rumor of her sleeping with Severus from spreading. She already earned some strange looks when walking down the corridors to her classes, it wouldn't be difficult for anyone to sell that story to Rita Skeeter.
Flora told her friends about the rumors she heard while they were on the way to the class they all shared together, N.E.W.T. Charms. She lied, saying it wasn't true. They gave her several ideas until Charles, of course, gave the most efficient, yet illegal idea.
"Secreseguri being poured into the water supply would end your problem."
"Not only is that illegal, but it takes two months to brew!" Flora said.
"How do you think my father got to be the Minister's personal potion master if he didn't know how to quicken a potion's brewing time?" Charles asked.
"If we got caught, I'd be sent to bloody Azkaban!" Flora said. "How are we going to get the ingredients anyways?"
"You're the one who has detention with Snape every night until the day you die, I'm sure you could come up with something." Lisa said.
"Do you think I have a death wish?" Flora asked.
"Would you rather be known as Laura Gregor II, or have Snape pissed at you for the rest of the year?" Tanner asked.
"Fine, I'll go to the library and find a book that has the potion." Flora said.
"Can't. It's in the restricted section." Charles said.
"Well, unlike you, Charles-Who-Almost-Got-Us-Caught-When-We-Went-To-Hogsmede-At-Midnight-Last-New-Years, I can maintain a disillusionment charm." Flora said.
"Ouch, no need to be a git." Charles said. "You'll also need potions ingredients, and for some reason, Professor Snape can see through even the best disillusionment charms. Oliver Wood got detention for a month after getting caught trying to get Felix Filicis from Snape's storeroom. So you're going to have to be good."
"I'm sure I can do it. I'll need the instructions of how to quicken the process to be within a day." Flora said.
"Done. You could probably actually find the very same brew quickener in Snape's storeroom. The stuff is worth a fortune, not even my dad uses it on every extensive potion. Pour a little water or something in it to replace the quickener and pray Snape won't realize until you're long gone from Hogwarts."
"Alright. Thank you. I will need some help putting different parts of the potion in different areas of the castle. Are you guys up to that?" Flora asked.
"Of course." Natasha said. "Since when have any of us, well, except you, have been opposed to breaking half the school rules and a few laws?"
"Thank you for your bravery and inability to care about rules." Flora said.
Later in detention, Flora had seduced her way into Severus Snape letting her tie him to the bed. She didn't use any old rope, she used a rope specifically designed to hold down large magical beasts, courtesy of Professor Hagrid being asleep and Flora being able to steal the rope.
So when she went from the dungeons to the first floor to get the ingredients she needed, Severus wouldn't have much of a chance of getting loose.
"I'll be right back." She said with a smirk before licking the head of Severus' cock and leaving the potions master nude and vulnerable.
She went as quickly as she could. She was able to get into her professor's personal storeroom by some form of luck and she opened her bag and looked down the copied ingredients list of the potion she needed.
She hurriedly found everything everything she needed except for the quickener. She scrambled, even trying to magically summon it a few times, to no avail.
"Looking for this, Miss Winterstead?" A frightfully familiar voice said from behind her. Flora gasped and veered to see her professor out of his bonds, fully dressed, and holding the quickener in his hand.
"Fuck." Flora muttered. "You're not going to hear me out on this one, are you?"
"I know you were planning on brewing Secresurgi. An appropriate response to keep the completely true rumor circling around Hogwarts from ending up on the front page, but had you not learned that the quickener in my hand has been sabotaged, you would have wasted risk and time."
"Sabotaged?" Flora asked. "How?"
"Charles Weston is not a fool. He knows he can sell this story and he will be believed. If he didn't help you find a potion, you would have had reasonable suspicion that he sold the story." Severus said. "I heard him talking about it with another Gryffindor. The boy has had a very low opinion of you of since you were unable to accept his Yule Ball invitation."
"What? But Charles has been my friend even before we started Hogwarts." Flora said. "It can't be true, he wouldn't do this to me." Flora scoffed. But she knew he definitely could have. He had treated her strangely after Yule Ball, he didn't write to her the summer before her seventh year, he wouldn't talk to her at any events. "Alright, fine, he would."
"I do find it insulting you came to your friends about the rumor before coming to me." Severus said. "Do you think I wouldn't have allowed you to quiet the rumors of our affair?"
"I don't know. I was just scared. I didn't know how you would react." Flora admitted.
"I will have the potion ready and administered a better way than the plumbing by tomorrow morning. I think you need to realize that I tend to have better ways of resolving conflicts than your little ministry friends." Severus said.
Flora was ashamed, she lowered her head a little, not looking Severus in the eye, her stomach low in her gut and she had the strangest sensation of death being seemingly more inviting than this moment.
Severus shut and locked the storeroom door and backed Flora up against the ladder. Flora adjusted so she sat on one of the steps. Flora spread her legs moaned when Severus kissed her hard, almost forcefully.
"You left me in anticipation. Were you planning to leave me like that for the whole night, or are you actually well mannered?" Severus asked before reaching up her skirt and pulling down her knickers. "Stealing from my storeroom and leaving me naked and bound? You'll be lucky if you can walk properly tomorrow." Severus said while undoing his trousers, pulling out his hard cock, and sliding it between Flora's legs.
Flora grimaced at how hard he fucked her, but it felt so damn good. She mewled repeatedly, she felt so delectably used. This wasn't gentle in the slightest, he was fucking her harder than a Knockturn Alley whore. Tears welled in her eyes, there was the smallest amount of blood between her legs.
Severus came quick. He left her needy and unsatisfied when it came to her own pleasure. But there was something she always found satisfying about Severus filling her pussy, flooding it so full of cum it overflowed and leaked out.
God damn what would have she done without him? He had saved her ass too many times, he satisfied her so much, and he was wonderful in a bizarre, untraditional way.
