Summary
After a tussle with a witch, Castiel's vessel is affected by a hex, turning him into a woman. Dean finds that his angel friend makes for a really hot girl, and an intimidating one at that, which stirs up all kinds of feelings long-buried about his friend. It's all made worse for Dean when female-Castiel scolds him for being reckless, and he likes it way more than he should.
When they manage to turn Cas back, Dean thinks his problem should be over. Until the next time Cas reprimands him for something. And the next. And the next. He's starting to feel like it's not a genderbend-specific problem. Then it becomes an even bigger problem when, fuck his life, Cas figures out what's going on.
Sam is laughing his ass off. Dean is not.

Blood(Lust) - A Revised Achillean Version by SheldarpCauseFuvkIt

Summary
Just some horny Mark of Cain action. The original is a Sapphic version with she/her pronouns and vulvas if that’s more your style. But I started hearing the dialogue in Jensen and Misha’s voices so here’s a more ‘canon compliant’ version.

Summary
"— Why? Why are you doing this now? — He asks anxiously and almost impatiently.
— Because I can. — He just says.
There's a lot left unsaid in that sentence. Sam isn't sure if Cas is referring to peace now that Chuck is no longer a part of it or because Dean has clearly rejected him. Sam is not sure he's supposed to enjoy the attention. In fact, he's sure he should value himself more right now. Sam should be with Eileen now, she had asked him for a date and he lied saying that he had already plans with Cas. He should be focusing on her and making things serious with her and not getting into this whirlwind of doubt. She doesn't bring up that kind of questioning, she's transparent, and she doesn't have anyone else in her life. Sam wanted that to be enough for him.
But is not…"
Edit: I've included a fanart on chapter 1 that I was afraid to post and not sure whether to post it or not, but it inspired me to write this fanfic so I'm posting it. Thank God ao3 is anonymous.
