Severus stared at his class; his fifth year Gryffindor/Slytherin class and took a deep breath. The bell had yet to ring, so naturally no one was paying any kind of attention to him. For once he was glad of this as he had just barely managed to struggle through his third year Slytherin/Hufflepuff class without doing something rash, though he'd been more than tempted to...Severus stopped the thought and willed his growing erection away just as the bell rang. He kept his eyes closed for a long time getting him self under control, not even noticing the silence in his dungeon classroom.
*~* Harry kept tossing nervous glances over his shoulder at his potion's professor. Snape was being abnormally quiet. Even though the bell hadn't rung, Snape would usually be yelling at them to take their seats by now. Finally, the bell rang and the room was immediately quiet as the students took their seats and waited for the lecture to begin. But it didn't. Since the first day of school, Snape had never once missed the first few seconds of his class. He always began talking as soon as the bell rang. No exceptions, but now he was sitting quietly at his desk, hands resting in his lap, eyes closed. As the minutes stretched and Snape said nothing they began to wonder if he'd fallen asleep. Someone suggested that they wake him up, but not even Draco Malfoy would approach the apparently sleeping potion's master. Gathering his courage, Harry carefully got out of his seat and moved to the front of the room. *~*
Severus felt a hand on his shoulder and opened his eyes sharply. He found himself starring into a set of emerald eyes through a layer of glass. Beautiful green eyes. With a shock he noticed his careful control was slipping as his erection stirred to life again.
"Are you alright, sir?" Harry asked cautiously. Snape swallowed hard and casually covered his now complete hardness. He'd never noticed how sexy the boy's voice was. Suddenly he realized that the classroom was completely silent and he was starring at Harry Potter. He gave himself a firm mental shake and glared at the boy.
"Locate your seat, Mr. Potter." He hissed, gathering himself and standing. Severus took a deep breath and steeled himself for another long class.
Harry watched his teacher curiously. It was an odd look he had seen in his professor's eyes for those few seconds and he didn't know if it frightened or intrigued him.
Severus didn't feel like eating. He excused himself from the great hall and quickly made his way to his quarters. Severus threw himself into a chair and tried desperately to ignore the flood of fantasies rushing against his mind's eye. He had managed to keep them mostly at bay during all of his classes, but now there were bombarding him with a vengeance. And to further his horror, most all of which involved a certain emerald-eyed celebrity. So of course, he was hard as a rock when he finally gleaned some control over the wild fantasies. Sighing, he eased a hand into his pants and gently stroked himself, but after several minuets it was doing absolutely nothing. His mind kept drifting to desk, to the drawer at the bottom and the plain redwood box under his teacher's edition fourth year potion's text. Finally he dropped his arm and stomped over to the desk, jerked the drawer open and pulled the box out. Throwing himself back into the chair he pulled the lid off.
Reaching into the box, he pulled out the letter.
“Dear Severus,
As I'm sure you've noticed, you cannot make yourself come. A little addition to the Sadism curse. However, I have not left you without avenues of relief. Of course all the forms of the originally curse are open to you, but since I've made it impossible to relieve yourself, I've given you a gift. You must of course use it sparingly; once it's gone, it's gone. Enjoy.”
Severus moaned and though he didn't want to accept whatever blackmailed aid Voldemort was offering him. His erection was straining so hard that it was painful. Giving in he located the instructions.
“Find a comfortable position, horizontal probably being the best.” Severus took the box and it's contents over to the bed and propped himself up on his pillows. “Remove clothing.” Within seconds, he was naked on his bed. "Fill quill with red ink.” Careful not to spill any of the blood red ink, he filled the quill and turned back to the instructions. “Draw line between inner hips. Draw line from each end to base of penis. This should form a triangle. Place quill on center of base line of triangle, and extend line directly through triangle and up erection.” Severus took a deep breath and pressed the point of the quill into the center of the triangle base hard enough to draw a bead of blood before dragging it in a steady line through the triangle, then taking his throbbing erection in one hand he ran the tip of the quill up the sensitive skin. He could feel heat building in his groin and as the quill ran over the head of his erection, it exploded suddenly. Severus screamed wordlessly as he came, his muscles trembling and breath hitched. Gathering some amount of strength, he looked down. The last line he had drawn had disappeared. He looked back at the letter. “To re-initiate the process, re-draw last line. Enjoy but use sparingly.” It warned. He carefully placed everything back in the box and set it on his bedside table before collapsing on his bed and immediately falling into an exhausted sleep.
