-1 Yeah...don't own Harry Potter :P

It went against every moral code that Sirius Black had set up for himself. The one big rule in his book was not to steal your best mate's girl. Even though Lily wasn't going out with James just yet, Sirius felt like he was having a secret affair with her behind his friend's back.

Who could he tell? Peter? Ha...that fat bum would go running off, and tell James. That left good old Remus...but would his friend except him after such a sinful act? Probably not...so he would be left to wallow in his own self pity, and then he would have to suffer Remus's never ending lecture of how he was right, and Sirius was wrong.

Lily's lips crashed against his once more, and he delightfully stuck his tongue between her lips, and was caught up in the taste of her mouth. His hand was on her smooth white neck, and his hands were dancing around the red strands of her hair.

Why was he kissing her?

How could he betray James like this?

The hand of his that wasn't entangled in her hair, was slowly trailing down her side, to her waist. They were alone in a deserted classroom, door locked in the middle of the night. Candles floated around the two teenagers, and Sirius knew he was in a dangerous position here. Sinful...this is what it was...it felt so right but, was so wrong. So why couldn't he stop?

Because, Sirius Black didn't want to, and being the stubborn teen he is, he wasn't going to let the whole sin thing bother him.

Not for now...

He kissed her harder with more passion, and pushed the thoughts to the back of his mind. Sinful or not Sirius Black didn't give a damn.
