Julius smile never faltered. It was easy to gain what he wanted from Professor Slughorn, and though he knew that he should feel disgusted that this was the way he bartered with the old man he honestly didn’t care. Leave it up to others to worry about being precious with things like this, Julius had very little to lose and a lot to gain.
He dipped his head, hand firm around the base of Slughorn’s cock, and licked. The taste wasn’t unpleasant – salty and with the musty, slightly sweet scent that seemed to hang around the man himself, a mixture Julius had learnt long ago of old potions equipment and candied pineapple. There was something comforting about it, about being here again on his knees. He took the head of Slughorn’s cock in his mouth, sucking softly, trying to make sure his teeth didn’t scrap as they had done the first time he’d attempted this. He’d sucked more than a few cocks since then but he always remembered that piece of advice.
