Looking for a specific S/X author

[liliaeth]

Have you ever had a part of a fic that keeps playing in your head to such a degree that you may remember that part, but not much more of the rest of the fic?


I know it was S/X, with Spike training Xander to be his slave. In order to do so he used some kind of pet feeder where Xander had to suck and lick the feeding tube that looked like a dildo to get any food out.


Anyway, I need to contact the writer of this fic, does anyone know what fic this is and who wrote it?
