That was almost all he needed- the boy's mouth sealed about him, the friction of the boy's lips moving over him was more than he could take, even as a young man it would have been maddening. He groaned, hips bucking up against Julius' mouth and briefly he remembered just how many other students, over the years, had been in the same position, knelt there, mouths filled, yearning for a job, a position, a favour only a friendly member of staff could offer. Julius was another student in the long line of students that had had ambition and the drive to do whatever it took to make their dreams reality. A better man would have considered it very wicked, very wicked, to take advantage of the students in such a way.
But Slughorn was not a better man, it seemed, and his grip on Julius tightened even more as he came against the boy's mouth, holding him close for those few precious, satisfying moments.
