"Very good, Julius. You remember your lessons."

"I will have to write a glowing reference for you. Quick to learn. dedicated. Friendly." Slughorn managed between intakes of breath. The attention bestowed upon his cock was making it somewhat difficult to think, to concentrate on anything other than the boy's mouth around him.
