I am desirous of fic

Okay, I know it's been approximately a hundred and one internet years since I've even nodded at Homestuck fandom, but someone, someone please!

I desperately need the story of the chaotic evil male human wizard and the lawful good demonic temptress from the underworld, the former finding himself enamored by a spirit of equally great beauty and thus striving to better himself in the hopes of pulling her out of the Hell in which she was born. I would read like a million pages of that. Double bonus points if the male wizard is a female wizard in disguise. (If you want to scrub serial numbers off and make it an original story, I would in no way object if the male wizard were trans* instead. I would probably celebrate, actually, and might even shower you with crocheted goodies, depending. It wouldn't be the first time.)

Alternately, the sexy fic in which Rose and Kanaya roleplay that in the bedroom would be equally acceptable.

(I have shipped some things hard in my time, but Rose and Kanaya are my ultimate OTP, my ship of ships, the pairing of my heart, and I don't think I will ever stop loving them.)
