I have just read the entire nearly ten-year-old Cable and Deadpool kink meme, so here, for your edification, is a summary of Cable & Deadpool comics canon derived almost entirely from kinkmeme fic by someone who has never read a single comic book with Cable in it, and also has not gone wiki-diving, because she doesn't know much but she knows better than to try to read a wiki entry for Cable.

(I know I should at least try the comics but I viscerally dislike most of the art of the relevant periods and avoid massive crossover events at all costs, and I tried reading the recent Deadpool & Spidey run, where the art was more tolerable, and adorable Dadpool is canon, but it was so homophobically queerbaity I threw it at the wall instead.)

Anyway, I got all I needed from fanfic osmosis. :P

( seriously why is *bodyslide by two* not a major slash trope yet )
