Draco took his hand and jammed pulled Harry's ass apart as far as it would go. Then, he jammed his cock in there, no lube. Harry let out a whimper in pain.
"Yeah, you like that, don't you? You like getting buggered without any lube like a bitchboy." Draco said.
Harry moaned in both pleasure and pain. His cock was nearly throbbing. It was so hard, so firm, it hurt. Tears went into Harry's eyes as Draco thrust in and out of his unlubed ass. He panted, he gasped, he grunted, he squealed. Then, as Draco thrust ever farther into Harry's rectum, Harry let out a deep long fart, and shit himself, all over his bed, and all over Draco's cock.
Draco was furious. "You disgusting little worm!" He screamed. He beat Harry over the head mercilessly, again and again. Harry cried and sniveled.
"I... I didn't..." Harry stammered. Draco smacked him.
"For getting your shit all over my majestic cock, you have to lick it off." Draco said, presenting his cock to Harry's mouth, covered in brown shit.
"Lick it! Now!" Draco shouted.
Harry obediently began to lick and suck on Draco's shit covered penis. The smell of it immediately killed any sexual arousal he had up until then. He cried some more. This was like a nightmare made real. Worse still, he was gagging on the shit he was being forced to eat. To his horror, he lost all control, and vomited all over Draco's cock.
Draco had had enough of this. He punched Harry in the face and pushed him to the ground. He took a clean piece of Harry's sheets and wiped the vomit and shit off of his cock, and finally zipped up his pants. "Gah, you're worthless! Potter, you're so worthless you're not even good for raping! I'm through with you! You're dead, you're fucking dead!" Draco said.
Draco made up his mind that the next part of Harry's punishment would be lethal. Harry would not survive. He would die that day, a victim of Draco's fury. Draco figured Harry would be sexier as corpse anyway. Dead boys didn't vomit or shit, after all, and Draco had no qualm about necrophilia.
How does Draco end this?
