Oh wow, this was great. I've always wanted to explore Peter's side of things, and you've done it beautifully. His nervous, shy thoughts and internal dialogue are just so right, and how he went from that, to Death Eater, betraying his friends and showing a squirming, uncertain loyalty to Voldemort, wonderfully consistent and well explained. And yes, the sex was hot! Perfect representation of both Peter and Lucius, and the Maurauders, too. Well done!
