Severus Snape surveyed his sixth year Slytherin and Gryffindor potions class. Ron and Harry were struggling desperately to save their potion, which was supposed to be a light lavender color, but was currently a deep green. Draco was slapping the muffins out of Crabbe's and Goyle's hands. Pansy was hitching up her skirt and batting her eyes at Draco in an attempt to gain his attention. But there, in the back of the class, was Neville, looking quite strange with his squinted eyes and half-open mouth.
Neville's hand flew silently up and down his engorged member. He was masturbating in potions, again. He couldn't help it. The sight of a certain potions professor always made him hot. Snape had just been reprimanding him for adding the potion ingredients in the wrong order, and the entire class had stared at him. Neville liked humiliation. Especially when it was caused by Snape.
Severus was perplexed by Neville's strange behavior. He stood up and moved ominously towards the back of the classroom, where Neville sat. Snape noticed one of Neville's arms moving rapidly up and down, his hand beneath the desk. Snape couldn't believe his eyes. Was Neville Longbottom jerking off in his classroom? Whatever would cause such an arousal?
"See me after class, Mr. Longbottom," Severus said. Neville's eyes flew open and he choked out a moan as he orgasmed.
The bell rang signaling the end of class. The rest of the students, oblivious to what had happened, filed out of the classroom. Neville, blushing, walked slowly up to the professor's desk and waited for him to speak.
"What were you doing during class?" Snape asked.
"Uhh, p-professor." Neville stuttered.
"Yes?" Snape stood and walked around his desk to Neville's side. He towered over Longbottom, glaring.
"I--" Neville started but before he could elaborate, Snape's hand was cupping his balls. Neville gasped as Snape fondled his most private areas.
The door burst open, revealing a smiling Draco. Neville squealed and backed away from Snape, pulling his robes around his front to hide his erection. Draco frowned.
"What are you doing?" he asked. Snape glared at him.
"We'd appreciate it if you'd leave the room. Now," Snape growled.
"But-- Don't I mean anything to you, Sevvy?" Draco pleaded with a heartbroken look on his face. Snape stalked towards him, causing Draco to back away, frightened. Finally, Malfoy turned and walked briskly out of the room, trying to hide his tears.
Snape turned back to Neville. "Now, where were we?"
"Wait. Were you and Draco. together?" Neville asked, wide-eyed.
"Never mind that," said Snape dismissively. His hand moved back to Neville's package. Neville moaned.
The door burst open again, and this time Draco had a knife. He rushed toward Neville, preparing to stab him.
"Expelliarmus!" Snape yelled, pointing his wand at Draco. "You stupid boy! Neville is my new plaything, get out of my life!"
Snape rushed towards Draco with his knife and stabbed him in the stomach three times. Draco grunted and fell to the ground, dead and bleeding. Snape gasped, looking at his bloody hands.
"What have I done!?" he exclaimed, slashing his throat with the knife in despair. Neville groaned and creamed his pants.
The bell rang and the first years entered Snape's classroom.
