After the sorting ceremony, Harry reported to the Headmaster's office as requested. "This year, Potter, you will dedicate your studies to advanced Dark Arts, as my apprentice." Harry shivered with fear, and...something else. Staring at the floor, he replied calmly "Yes, Sir." He shifted nervously, adjusting his tie. Looking up, he found Snape was no longer behind the desk. Before he could turn his head, he felt the air change behind him, and a gravelly whisper curled into his ear. "Do you have a problem with that, Mr. Potter?" Snape pressed into his back, more with energy than physically. But, Harry's cock sprang to attention. Thank god for robes! "Er, no, Sir." He fidgeted, trapped as he was between Snape and the desk. If he tried to turn around, they would be nose to nose. If he moved forward, he would be bent over the desk. Hmmm. "That's good." They stood like that for a long moment, until Harry became aware that Snapes hands were snaking around his waist, slithering toward a gap in his robes, and a suggestive hardness pressed into his backside. "You will be of great help to me, I am quite sure."Silken lips grazed the back of his neck.
