Written for Scavenger Hunt Competition.
Severus Snape couldn't believe they were once again in his bed, he'd told himself time and time again that every time would be the last time. But he couldn't fight the attraction that was between no matter how hard he tried and he had tried.
She was his student, best friends with Potter and there was that oh so alarming thing of her being a Muggleborn and him being a Death Eater; he couldn't imagine the Dark Lord slapping him one the back and saying "Well done you're sleeping with someone who we'd really like to kill".
No, the Dark Lord would torture him and then let Bellatrix torture him until he insane then if he were lucky the Dark Lord would kill.
Yes, being with her was likely to result end his destruction but he couldn't stop being with her.
She was his greatest weakness.
