Hermione slipped back into her house thankful that Ron was still out. She sighed flopping into a chair.

"I just...did that, fuck. Ron's going to kill me...no, I...I can't let him find out. It was a one time thing, just put it out of my mind," she told herself. She nodded already pushing the whole event to the back of her mind.

As she got ready for bed, she couldn't stop thinking about the events of the day. Couldn't stop thinking about his hands on her, how he responded to her every sound. Ron never did that.

"Ron is your husband, knock this off," she muttered to herself. She glanced at herself in the mirror. She still looked like herself, not like a woman who would cheat. Her eyes fell on the book hidden under her nightstand.

"The potion. I can blame it on the potion, yes, I would never do something like that. I don't even have to see him again." She smiled crawling into bed.

The next morning, Ron woke her.

"'Mione, there's an owl for you." She yawned stretching. She hadn't heard Ron come in last night. She must have been tired. She walked over to the window. Ron had opened it and allowed the owl inside. She reached out and took a small bag from it's leg. She recognized Professor Snape's apothicary's mark on the bag.

"Anything good?" Ron asked as Hermione gave the owl her payment.

"Just a potion I ordered."

"For?" Hermione rolled her eyes. She knew Ron thought the whole mental illness thing was a bunch of thestral shit and she was getting tired of trying to explain it to him.

"Girl things," she stated watching his reaction. As she expected he made a face but didn't ask any more questions. It wasn't like he tracked her cycle anyway.

"Now that you're up, breakfast?" She sighed. She knew she'd been making breakfast every day for the last week, but today, she really just wanted to snap at him. She didn't, still feeling guilty. The thought of Professor Snape against her body, the thought of his hands on her. She couldn't get it out of her mind. What was this feeling? It wasn't anything like she felt for Ron.

So lost in her thoughts, she managed to burn breakfast to a crisp.

"What the hell is wrong with you today, 'Mione?" She only shook her head.

"Why don't we just go out to breakfast?" she suggested. Ron nodded.

"Good idea, it's been awhile since I've been able to show you off, get dressed in something else. Maybe that set of blue robes?" She sighed but complied. They apparated to the Brunch Nook, a small cafe in Diagon Alley. Hermoine nibbled on her muffin while Ron ate a large plate of eggs, sausage, and rolls. Something outside the window caught Hermione's attention. A person in black billowing robes, Professor Snape.

"What are you looking at?"

"Nothing," she lied turning her attention back to Ron and his story about something involving a broom and the quaffle.

"Was it Snape? Is that who you were looking at?"

"And if I was? What's it to you, Ron."

"He's a creep, Hermione. I know you've been to his shop."

"You're following me now? What the hell Ron?"

"I wasn't. I was going to surprise you at work, and you had just left...you went there."

"He makes the potion I'm taking."

"For what?"

"Depression."

"Back to that mental nonsense? I've told you, there's nothing wrong with your brain. Just take a cheering charm. I don't want you anywhere near him."

"Why? Why shouldn't I get my potions from him? He's the best at it. Besides, it's not like I'm out every night with people racking up a tab at the Cauldron. Hannah told me."

"You don't understand, Hermione. Just stay away from Snape." Ron paid for their breakfast and stormed off. Hermione took half a second before deciding not to follow him.

Instead she made her way down the street. She found herself in front of Professor Snape's shop. Slowly she opened the door. He wouldn't want to see her, not today, probably not ever. She knew she should apologize for yesterday, but the thought of him with her still sent shivers of pleasure over her body.

"Miss Granger? To what do I owe the pleasure?" She smiled at him.

"I was thinking...about yesterday, sir."

"My office, now." She nodded following him. He was already at his desk when she entered and slid into her usual seat.

"Now what, Miss Granger?"

"I can't stop thinking about you, sir."

"That's a first. You have a husband, Miss Granger."

"I want you. No, don't tell me it's just the medicine, thank you for sending it, by the way. Yesterday was nothing like anything I've experienced. I can't...I burned breakfast thinking about your hands on my skin."

"One minute, Miss Granger," he stepped out into the main store, ordered someone to watch the shop and returned.

"We shouldn't."

"No, we shouldn't...but..." her voice had a slight hopeful tone, one he almost couldn't resist. He led her back to his chamber. She stood there, biting her lip. He wondered if she was going to back out.

"You don't have to do this, Miss Granger. I am not forcing you into anything. Does you marriage have a fidelity clause?"

"I think it's a bit late to worry about that, sir," she whispered bringing her lips to his.

"Severus. My name is Severus, you will call me by it." She nodded pushing her body against his as they maneuvered towards the bed. She pushed him down climbing on top. He smirked rolling over so she was on her back. She looked up at him, her eyes burning with desire. He could feel himself harden just looking at her.

"Please," she whispered. He nodded kissing her slowly, her hands wrapping around his neck. With a flick of his wrist he vanished all their clothing. Hermione wrapped her legs around his waist, pulling herself onto his erect member. Her moans set him off, as he pushed her down hard against the bed. Her fingernails claws at his back as he thrust.

"Gods witch, you're tight," he whispered in her ear. She moaned softly bringing her lips to his. His hands moved up her body, pausing at her breasts. Slowly he spread his fingers over them, touching her nipples slightly. She arched her back in pleasure.

"You like that," he whispered, his lips brushing against her ear.

"Yes," she hissed, a sound that made him jut against her harder, his cock deep in her.

"You're about to finish me, witch," he stated. She laughed arching against him, her breasts pressed against his chest.

"Then go," she ordered. She moaned loudly as he came, her body tight against his. She only took a minute to follow suit, panting heavily as she looked up into his black eyes.

"I love you," she whispered. He stared at her in disbelief, in shock as she closed her eyes in ecstacy.

"Damn it, Hermione," he whispered laying on the bed next to her and watching her glow in bliss.

It was half an hour later, Hermione had fallen asleep. Severus hadn't had the will to wake her. Slowly she blinked her eyes open.

"Where, oh...shit."

"I think that word describes things pretty well, Miss Granger."

"I swore I wouldn't...that it was a one time thing."

"You said you loved me, Miss Granger." She froze, her eyes wide as she searched through her emotions. Severus tossed her her clothing and she dressed numbly.

"About what I said earlier, I think..I think I..."

"Don't. Don't even think about saying those words. You don't love me, you're barely capable of loving yourself. All you're feeling right now is an after affect of what we just did. If that's all it takes to make you love someone, then go shag your husband and maybe you'll love him instead." Hermione bit back tears. She'd been with Ron multiple times.

"It's different with you, you make me feel things."

"Feel what, embarrassment that you cheated, that I...I took advantage of you, I never should have allowed you up here the first time. I should have just altered the potion like you needed...just healed your arm, and sent you on your way. I took advantage of you."

"I don't see it that way."

"Of course you don't. And now you think you're in love with me, Merlin, what did I do to deserve this? Just get out." Hermione bit back tears.

"Severus...I..."

"Mrs. Weasley, please just leave. I do not want to see you anywhere near my shop again. I do not want anything to do with you." She let the tears fall as she left the shop, nearly running until she realized she had no where to go. She'd fought with Ron and now... Biting back her pride, she apparated home, glad to see their house was empty.
