Severus Snape arrived at the burrow at Molly Weasley's personal request. He knew she was not pleased with him after he gave Ron a months detention as a punishment for Harry's mistake.

"Molly." Snape nodded as he exited the fireplace. "Ive just put the kettle on Severus, may I tempt you with a cup of tea?" Molly offered politely. "Yes, thank you." Snape thanked her as she poured the tea into her finest China.

"What is it you need to talk to me about Molly?" Snape asked nervously, he knew full well what it was about, but the silence was awkward. You see for quite a while Snape has found himself admiring the witch at meetings with the order, he found her attractive in so many ways. Although he hated to admit it to himself, the thought of falling for a Weasley made him cringe.

"Severus, I won't stand for your behaviour to my son. Ronald had nothing to do with the book that went missing from your chambers! Harry himself admitted to taking it using his invisibility cloak." Molly scowled sternly, "Yes, I'm aware it was Harry and he as been punished accordingly. However, as I have already given your son a punishment I cannot backtrack on that. I cannot be seen as weak." Snape explained, he felt terrible.
Not for Ron, but for Molly. He couldn't bare to upset her.

"I understand, but please in to the bottom of the situation before you punish." Molly sighed, "of course" Snape smirked sexily. "Are those new robes Severus? I haven't seen you wearing those before. And you're hair is looking in perfect condition!" Molly smiled, blushing a little. She loved Arthur of course, but there was always something rather attractive about Severus Snape. He was the perfect forbidden fruit.

Snape snorted as he listened to Molly's internal monologue. "Oh My! Severus! I do apologise you weren't meant to hear any of that! Come to think of it why were you using legimency on me?" Molly blushed, "I wanted to know what you were thinking, I wondered if there was even a small chance that your thoughts matched mine. I can see now that I was in luck." Snape drawled sexily, moving slowly towards Molly who was now stood with her back turned to him, to embarrassed to face him.

He wrapped his arms around her waist and rested his chin soon her chunky shoulders,
"What about Arthur?" Molly asked, shuddering at his touch. "It can be our secret.... I don't want to cause any trouble. Not until you decided to leave him anyway.." Snape reassured the witch. He placed gentle kisses on her neck and she moaned. "What about the age difference Severus? I'm at least 10 years older than you... I'm not a young beauty anymore..." Molly sighed. "I like a more... Mature woman Molly." Severus gasped as his hands traced her ample bust. He spun her around and kissed her passionately.

"We must stop! Arthur will be home soon." Molly explained pulling away. "5 more minutes....." Snape chuckled pulling her back. "No, we must stop! I must get Arthur's sausage in my oven. He'll have worked up quite the appetite at the ministry.
"He better not put his sausage anywhere near your oven, my love" Snape smirked.
"I meant his dinner! you have a very filthy mind Severus Snape!" Molly giggled like a naughty school girl. "Well, my filthy mind will be of good use to you. If you allow me to use it...." Snape explained silkily. "We shall meet somewhere else Severus. And I can assure you Arthur and me are not... Those days are gone." Molly promised.

Snape headed to the fireplace to floo to Hogsmeade, after begging Molly to send word by owl. She nodded and smiled gently. And with two words he disappeared....
"Diagon Alley."
