OHOHOHOHO Hold oh my cute danish penis I love dark!will fics
um but I wasn’t sure if you wanted like dark will as in darkfic or just different alignment fics (ie serial killer will) so I included a bit of both c: I don’t think there is that much of this even though I love it so I probably haven’t recced anything groundbreaking but yeah here they are anyways
there is DarkmoonSigel’s the notes played inbetween which personally isn’t always my cup of tea in terms of narrative voice/style but does have a bunch of fics about dark or serial killer will which makes me pretty happy http://archiveofourown.org/series/47214
It’s third of a series, but you don’t have to have read the first two, althought they’re both pretty good, and there’s a part in this fic that makes me quiver with delight at how dark will is http://archiveofourown.org/works/823402
what if the first time dean had sex with a girl, dean was bragging about it for weeks and sam was getting all angry and jealous. and then dean was fucking sam one day and was like "come on sammy. she wasn't anything special. no not like you. you're so much tighter sammy. oh you feel so good"
dean reminding jealous!sammy that he’s the only one that matters (✿◠‿◠)
