whoops

why is it that whenever I try to write porn it just turns into some long, rambling character study and rarely actually gets to porn? Seriously, this is becoming an issue. Or maybe not an issue because it makes for some good fics, but still, one day i'd like to be able to write hot crackship smut without it turning into either character studies or, on one memorable occasion, a supernatural/bloodborne crossover. 

It was just meant to be Sabriel for a friend.
how did it turn into that.
