Hermione had been in the lab for hours, attempting a complicated experiment in which she might be able to triple the size of a Wolfsbane batch without it losing any integrity. Doubling it was certainly difficult enough, but she was able to manage it eventually. The next step was clear, she needed to triple it. She knew she wasn't supposed to be in here, but she simply couldn't resist. She had a shitty week and she was unreasonably stressed out. She needed to get her mind off of everything and brewing usually helped. Besides, if she could accomplish this, something her mentor had not, she would finally be able to step outside of his shadow. She ran the numbers dozens of times, she knew she had it figured out.
She was to the left of the cauldron, cleaning up the workspace while the potion simmered for the required 23 minutes. She had been so focused on the cauldron to her right that she hadn’t heard him come back through the floo. She had not heard him come down the stairs nor enter the room. She had been so focused on the work in front of her that she completely missed the growing presence behind her. “What do you think you are doing?” She knew he was going to be upset, but hoped he would see reason.
“I finished my calculations and thought-”
“You are not supposed to be in here!”
“I’m almost done. I think I have it figured out. I needed to try! I just thought-” she paused when his hands reached around to her front and started to unbutton her shirt.
“You thought what, Ms Granger? That you could come in here whenever you please?” Her shirt fell to the floor. “What about pleasing me?” He was kissing her up and down her neck, feeling the goosebumps beneath his lips.
His tongue caressed the outside of her ear as his left hand dipped into her leggings. “I- uh- t-this isn’t a g-guh...” She wanted to tell him that this wasn’t a good time. She only had 11 minutes left before she needed to move on to the next step of the potion and she’d be damned if he got in the way.
“You still want to please me, don’t you, Ms Granger?” His fingers were already working their magic and she was close to climaxing, a few more swipes and she would come right into his hand.
“Yes.” He pulled his hand out. She should have known better. He started to push her forward, but she was able to lay on a table like she used to. “Careful! You can’t just-”
“I can do what I want.” He grabbed her hands and placed them together on the table and she felt a tingling in her palms. She didn’t need to try to move them in order to know that she wouldn’t be able to.
“Hey!” He pulled on her hips so that she had to take a step back and was then pushed down so her chest and face rested on the tabletop, her hands still stuck down on the table, not far from her head. The heat from the cauldron was close enough to burn her if she shifted accidentally. While the thought of such recklessness was arousing, the trust she had in the man to keep her safe was even more so. “Please, the potion is almost-” Everything disappeared. He vanished everything! Everything she had been working toward. “What in Godric’s name do you think you are doi-?”
“I do not appreciate your tone, Ms Granger.” He vanished the rest of her clothes. “I was going to make this good for both of us, but perhaps I will only make this good for myself if this is how you will behave.” She felt his body lean over her own, she was encased in his warmth. Not that she would dream of it, but there was a better chance of Azkaban than escaping him now. She was his. “Although, maybe after sufficient punishment, I will treat you as well, even though you have been so unbearable lately.” His fingers found her clit again and the tension in her core quickly rose as she was denied her previous release. “How many strikes do you deserve for your egregious violations?”
"Uhh…" she was already breathing heavily, making it difficult to speak. She could barely think and she already forgot what her ‘egregious violations’ were. "Five?"
"Five? Oh, no no no, I think you seriously underestimate the severity of your actions. Was I not clear that you are not to be in here unsupervised?"
"Unsupervised? Now, really. That's ridiculous. I am not a child!"
"You certainly are behaving like one, Ms Granger .” His hand removed from her, ceasing all pleasure. “Did I imagine it, or have you lost all sense of formality?"
"Ten might have sufficed before that unwarranted outburst." She rolled her eyes. Unwarranted, my as- "and you didn't answer my question, so how many shall it be now?"
"That's more like it." He stood up. “You know what to do.”
With a loud THWAP, she felt the stinging of her first strike. “One. Thank you, sir.” THWAP. “Two. Thank you, sir.” He wasn’t striking her as hard as he has in the past, and she knew why. Honestly, it was probably for the better as she was unusually sore today. THAWP! This is not what she needed though. She had been stressed all week. Everything was getting on her nerves. THWAP. “Six. Thank you, sir.” She thought brewing would take her mind off things and possibly accomplishing her goal would give her a reason to celebrate. But she was probably more anxious than when she started, and then he came and took it all away with the wave of a hand. THWAP. “Ten. Thank you, sir.” She was pissed. THWAP. She was pissed at him. THWAP. She was pissed at herself. THWAP. She wanted to cry. THWAP. She started to cry. THWAP. She couldn’t tell if it was from the pain in her ass or the accumulation of everything. THWAP. Though she knew better than to keep it all in, she couldn’t help but try to. A full breakdown was not on her books for today. THWAP. With one last strike, her resolve crumbled and she broke down.
He allowed her a moment to collect herself. “Are you ready now, Ms Granger?”
“Yes, sir.” There was no other foreplay before she felt him ram into her. It was fast and quick, and as unromantic as possible, but everything that she needed. Her climax built rapidly and she was coming undone before she had the time to process that it was happening. A few more thrust and he joined her with a satisfying grunt.
Her hands were released from the table and she stood up on wobbly legs. “Well, that was unexpected. What brought that on, Severus?”
“Do I need a reason to fuck my wife?”
"How lovely." She was unamused. “Regardless,” she closed her eyes and sighed in relief. “Thank you. I think that was exactly what I needed.”
"Yes, you seemed to be having a hard go of it lately. Speaking of which, you shouldn't be in here. You're supposed to be in bed."
"The healer said nothing of bed rest, Severus. She only said I needed to take it easyyyy-AHH." Mid word, she was scooped off her feet into her husband's arms. "What in Merlin's name are you doing?"
"You shouldn't be walking."
"Walking? Severus, I can walk one flight of stairs and down the hall!"
"No, no. I will carry you."
"My muscles need stimulation."
"I'll stimulate your muscles."
"I mean, I will massage your legs."
"That is not the same thing! They need activity, my legs need to move."
"I'll move your legs for you."
"Godric bless this child. You are going to smother this poor girl, aren't you?"
“I’ll let you smother me right now.”
“You are absolutely incorrigible.” She looked down the steps into the lab and remembered something. “You! You ruined my potion!”
