Unlike Homura, Madoka's not so much the kind of person to deny and loathe her desires for being sinful. So even if going TOO far might wake up the goddess, it makes sense for a Madoka who's allowed her feelings to overwhelm the universe to engage in some devilish temptation. Or teasing, if that's what you want to call it~
Murmur is a blessing and a gem. Absolutely SEARING hot. Incredible dynamic between adult women (thank god), who are, frankly, not good people and not good to each other and make an awesome, banging story.
that's really the most compelling part of it. i recently ("recently", probably years ago) tried rewatching it and couldn't make it halfway through season 1. but the OP is so good!!!!!!
