Oh, hi, nice to hear from you. ^^

There are actually a few more or less helpful sites out there, yes. The scene is finished by now (the fic is called Blessed with sin and also posted on ff.net, if you're interested ;)), and though it's certainly not the best smut ever, I'm halfway happy with it. It's okay, I think. Still, smut scenes will probably remain my nightmare when it comes to writing fanfiction for quite some time. ;)
