Disclaimer: I do not own Harry Potter or any other of J.K Rowling's creations. I don't own, you don't sue! I do however own Annabel as she is a character I have created.

My first Harry Potter fanfic so please review, I need help with ideas! Excuse my crappy spelling and grammar as well as I am only 15.

Note: It's now a 20 chapter fic but I'm considering making it longer. Sorry for adding more again. Upcoming chapter is 'The Aftermath' chap 16.

Let we know if I should continue the story.

Couldn't fit everything in 12 chapters so it's going to be 20 chapters long or more.

OOOOOOOOOOOOOOO

Chapter 15: An Affair To Forget

'I think it's cute,' muttered Tracy as she watched Sirius being dragged away by McGonagall.

'Utterly adorable,' commented Betty, eyeing Sirius's skimpy outfit with lustful eyes. Tracy scowled.

'You have no right to be looking at my boyfriend like that!' snapped Tracy.

'Boyfriend my ass. Sirius is a tired spirit, born to roam free. Nobody can tame him, for he is a wild beast,' breathed Roxanne, gazing at the object of their affections who was trailing after the professor.

'Shut up Roxanne!' the others bellowed.

OOOOOOOOOOOOOOO

'But baby, why are you doing this?' whined Sirius as McGonagall pushed him back towards the castle.

'Because you were stupid enough to bewitch those girls into liking you, for your own personal…pleasure,' said Professor McGonagall sharply waving a dismal hand at the Ravenclaw's behind them, who were all staring at Sirius.

'It's not my fault I'm so amazing sexy. It's natural attraction only,' Sirius beamed, waving goodbye to his fan club as they passed into Hogwarts and exited Hogsmead.

'Mr Black, old I may be, stupid I am not,' hissed the Professor, slowly mounting the steps to Hogwarts. Sirius pouted.

'Are you saying that I, most handsomest man in all of Hogwarts, needed a love potion to get laid?' he cried, looking hurt and staring up at McGonagall through puppy dog eyes, causing her to scowl.

'Not in those words exactly, but it is undeniable that you used a love potion,' she answered awkwardly, but still maintaining her stern expression.

'Humph!' Sirius grumbled, crossing his arms over his bare chest.

'Mr Lupin is staying with the girls in Hogsmeads until I have consulted the head master about your antics. Rest assured you will be punished accordingly,' said McGonagall casting a sideways glance at Sirius who was combing his hair with his fingers, unfazed by her words.

'Right you are baby,' he simpered as they made there way to Dumbledore's office.

'Don't call me baby and for gods sake take of that ridiculous costume!'

'See. I knew you would prefer me to wear nothing,' grinned Sirius, beginning to unfasten the material.

'Black!' screamed McGonagall.

OOOOOOOOOOOOOOO

'What the hell do you want?' hissed James, glaring at the new arrival as he tried to detangle himself from Lily's robes.

'And what are you doing?' smirked Snape, his eyebrows raised as Lily again attempted to pull herself closer to James.

'None of your business,' James snapped, holding a agitated looking Lily back with one arm. Snape smiled.

'I think it is. I mean especially considering a teacher could walk by at any moment,' he replied, looking mildly surprised at Lily's forcefulness to get James. She was again pressed up against him as he struggled to escape, her hands roaming uncontrollably over his body. Snape looked slightly interested but disgusted at the same time.

'So what do you want?' James asked, becoming less aggressive as he glanced along the corridors nervously. All Snape needed to do was call a teacher and both he and Lily would be in detention forever.

'Her,' Snape answered simply, pointing to Lily, who had now freed herself from her robes and was forcing James's hands over her, oblivious to the fact that Snape was even there.

'What!' cried James, giving up his losing battle to Lily and staring at Snape as his girlfriend began to run her lips down his neck, spurred on by his now lack of resistance.

'Well simple thing is, you want her, so I want her,' Snape said smugly, eyeing Lily's body lustfully. James scowled, pushing Lily off him and advancing on Snape.

'She'd never do it. And I'll never let her,' murmured James, his voice dangerously low.

'Oh really. Well she seems to be up for anything at the moment,' laughed Snape, his eyes darting to Lily in her underwear. James pounced in front of her, blocking out Snapes view protectively.

'She may be…under the influence, but she's not stupid. She's not that desperate,' said James, trying to cover her petite body from Snape's roaming eyes.

'She seems pretty desperate to me. I'll give her what your refusing to,' he replied, eyes glinting. James was unable to answer but looked disgusted. Lily meanwhile was looking between them, trying to continue her advances.

Snape was right. She was desperate. She needed James now, but he was refusing to cooperate. She wanted him so much and she wasn't sure why. The small voice in the back of her head reawakened, screaming at her to stop.

What are you doing woman? Do you have any control? hissed the voice, becoming clearer.

I want this, was what the potion answered back.

You want to be standing in a closet in your underwear with Snape looking at you? screamed her mind, telling her that it was wrong. Lily mildly registered that this was true. Why was she letting Snape ogle at her almost naked? Suddenly she hid behind James, who was surprised by her sudden actions.

'To late now Evans. I've seen it all,' laughed Snape as Lily let out a gasp of surprise, her mind suddenly coming into focus.

He's right. He's seen you now. No point in hiding. Maybe he can give you what you want if James won't, said the other voice, urging her towards Snape.

What that's crazy! her conscience replied desperately. But it was to late. Within seconds Lily had made up her mind. Springing out from behind James, she dove forwards into Snape, connecting with his lips.

All sense of reason was lost as the potion consumed her once more, driving her on. James watched in amazement as Lily's and Snape's lips began to move against each other, tongues beginning to touch…

OOOOOOOOOOOOOOOO

'Mister Black! You dare!' cried McGonagall fearfully as Sirius began to remove the scrap of material that was his costume.

'You said take it off,' Sirius replied, tugging on the strings holding it together.

'Not now. What the hell is wrong with you? For god sakes man, COVER YOURSELF!' she exclaimed in desperation, her hat falling off and landing on the floor.

'I believe in miracles, dun dun, where you from? You sexy thing,' sang Sirius happily, removing it completely as McGonagall conjured a table in front of him at that very moment. Sirius seeing this, laughed with glee. Throwing his head back, he jumped upon the table wearing nothing but a small pink thong, that he had apparently also bought at the costume shop. Professor McGonagall shrieked, all dignity forgotten, as Sirius began to dance, waving is hips seductively.

'I am beautiful, in every single way,' he sang heartily, unaware of the Headmaster who had come up behind him, a amused glint in his eye…

To be continued…

A/N Sorry this chapter is pretty short but I wanted to get it up quickly. Next chapter is 'The Aftermath' where everyone has to deal with the consequences of their actions. Hope you enjoyed.
