This was written around 2 a.m. about a month ago. It's not beta-d or anything, so I apologize for any mistakes.
Story contains Remus/Sirius, unrequited Remus/Tonks, unrequited Kingsley/Tonks.
Disclaimer: Sadly, J.K. Rowling thought of it first. Not me.
I love Tonks. Really. Just not the same way that I love Sirius.
I could ask her to morph into him, and she would probably say yes because I wanted it. I could, but I won't. That's because I know it wouldn't be the same as having him. Tonks can't talk about the Marauder's years at Hogwarts because she wasn't there. She doesn't have the spots on Sirius's neck that would make him moan when touched just so. And it makes me feel guilty because I'm still in love with him, but married to her.
I still have the ring Sirius gave me in Seventh Year. I guess you could call it a promise ring since men aren't allowed to marry each other. I wish it weren't illegal and people weren't so damned prejuidiced. Then maybe Sirius and I wouldn't have hidden our relationship, and I wouldn't have gotten involved with Tonks. I have to admit I'm suprised she still hasn't figured it out. I'm sure Molly knows because, well, nothing gets past her. Moody and Kingsley probably know too.
I can smell Kingsley's lust whenever Tonks is around and I think Why couldn't she have fallen for him? Life would be considerably less complicated if she had.
