A/N: I do not own Harry Potter or any related characters.

Warning: This chapter contains almost non-con, it doesn't get that far, but be warned.

The next two days seemed like she was walking on a cloud. She took the potion in the morning and by the time she'd finished poking at her breakfast it seemed to be doing something. She'd doubled checked the book, but it only confirmed what Professor Snape had said.

It was nearing noon on the second day when she made her way towards Diagon Alley, towards Professor Snape's shop. She stopped at the ice cream shop along with way and bought herself a chocolate cone with cherry topping. She couldn't remember the last time she'd actually enjoyed something.

"Good afternoon," she announced walking into the shop. Professor Snape was behind the counter and looked up in surprise at hearing her voice. He motioned for a shop hand to take over and walked towards her.

"Good afternoon, Miss Granger, no, I'm not going to call you by his name, I know you hate it."

"Thank you, sir."

"Why don't we adjourn to my office so we can discuss how your treatment is going in private?" She nodded following him to a back room. She slid into the leather chair and he sat across from her at his desk. She recognized it as the one from his office at school.

"How are you feeling, Miss Granger?"

"Amazing," she answered truthfully. "I actually ate an ice cream cone on the way here and enjoyed it, I don't know the last time I actually enjoyed something, sir. Thank you, so much."

"I'm glad the potion is working, have you experienced any side-effects?" She couldn't help staring at him, at the way his hands moved when he spoke, at his hair, his eyes. She leaned over the desk slightly using a non-verbal spell to undo the top button of her blouse. He didn't notice.

"I don't believe so, sir. But it's only been two days."

"Yes, some of them do tend to be immediate, such as if you were to be allergic to the potion or one of its ingredients."

"Oh," she whispered opening her eyes wide. Professor Snape blinked a few times staring at her.

"Are you alright, Miss Granger?"

"It's just a little warm in here, sir," she answered.

"Let me get you a water," he offered noticing her face was in fact flushed. She nodded as he left the room. She quickly undid another button on her blouse, wondering why she'd never felt this way with Ron. He returned with a cup of water and handed it to her. She slowly took a sip watching him from over the rim of the glass. He had his back turned towards her at the moment and she couldn't help but admire his butt.

She wondered exactly what to do about the way she was currently feeling, the lust building in her. She was married, damn it! Ron would be back soon, she reminded herself. She was so busy trying to ignore the feelings that she managed to dump the water down her blouse instead of taking a drink.

"Shit," she muttered. He turned and noticed her blouse, noticed the undone buttons.

"Another side-effect of the potion can be an increased libido," he stated handing her a tissue to dry her shirt. She nodded dabbing the damp spot.

"The book didn't mention that," she commented.

"I'll have to make sure to write the author. I might need to adjust your dosage, Miss Granger, if the side-effects are too determental to your everyday life."

"Thank you, sir," she responded standing up. He started walking her towards the door of the office when she turned and kissed him roughly. He froze, her hands grabbed at his shirt. Slowly she started unbuttoning it. He reached up to stop her.

"Miss Granger." She pulled back sheepishly, her face flushed. Part of him wanted her to continue, he hadn't had the touch of a woman in a long time. He shook those thoughts from his head. He couldn't. She didn't feel anything towards him, it was just a side-effect of the potion.

"I'm sorry, sir, I don't know what came over me."

"Definitely an adjustment," he stated. They walked back out into the main part of the shop. He paused at the desk to jot down something and grabbed a small vial.

"Take one drop of this with the five remaining doses, Miss Granger. It should curtail this particular side-effect." She nodded taking it and placing it in her bag.

"I'm sorry, sir."

"It's alright, Miss Granger, if there are any more problems, please come see me, or go to St. Mungo's depending on the situation."

"Yes, sir," she agreed before leaving. He watched her leave and sighed with relief. If she had tried to go at him again, he wasn't sure he would have been able to stop himself.

"Watch the shop a bit longer," he ordered his assistant before going upstairs to his personal flat and taking a very, very cold shower.
