They drew their wands at the same time.
“Expelliarmus!”
“Imperio!”
Snape’s wand flew from his hand, but not before he had uttered the curse. Slowly, he picked up his wand and approached Sirius.
“Drop your wand” he said.
Sirius dropped his wand.
“Good. Now, we’re going to have a little fun, you and I.”
He saw fear in Sirius’s eyes as he realised he was completely under the under man’s control.
“Now, get down on your knees.”
Sirius could do nothing but obey. He got down on his knees.
With a flick of his wand, Snape tore Sirius’s clothes off, leaving him naked, vulnerable and shivering.
“Hold out your hands” he ordered. Sirius obeyed, and Snape let ropes fly out of his wand, tightly tying his enemy’s hands together. He felt his cock grow harder when he saw the ropes tighten around Sirius’s wrists, cutting into his skin.
“Now look at me.”
Sirius lifted his head and looked at his enemy. There was defiance there, and Snape was determined to wipe it from his face.
“I believe you’ve done this before” he whispered. “You worthless whore.”
He reached inside his robes and unfastened his belt, slowly pulling out his cock from the confines of his trousers as he watched Sirius hungrily, growing even harder with anticipation when he saw the blank stare of those grey eyes. Sirius Black on his knees before him, waiting to be fucked, humiliated and broken. Oh yes, he was going to enjoy this.
Sirius watched in disbelief as Snape pulled out his cock. Never would he have thought that it would look like that, so thick and heavy.
“Please…” he said. “Don’t do this. I beg you, Severus.”
“Oh, so it’s Severus now, is it? Forget it, Black. You look so good on your knees like this, helpless and at my mercy. But believe me, there will be no mercy. You let the werewolf do anything he wants with you, as the whore you are. But tonight, you’re mine.”
He tried to resist the urge to grab hold of Sirius’s hair and force his cock in between his lips.
“Open your mouth” he said.
Sirius could do nothing but to obey.
Snape held his cock in his hand and took a step forward until his throbbing length was almost touching Sirius’s face.
“Now, take it into your mouth and suck it.”
He brushed his cock against Sirius’s cheek, then over his lips, leaving a glistening trail of pre-come. Sirius swallowed hard, closing his eyes.
He suddenly found himself leaning forward, closing his lips around Snape’s cock and sucking desperately. And he knew that everything was too late now. The only thing he could do was to finish his enemy off as quickly as possible, to let him come in his mouth and then it would all be over. His head moved erratically back and forth as his mouth moved quickly around Snape’s hard cock.
Snape took hold of his hair and pulled him back.
“Slower” he murmured. “You filthy whore, can’t get enough, can you?”
Sirius whimpered and slowed down his pace. Snape threaded his fingers almost gently through his black curls, slowly thrusting back and forth into that hot, unwilling mouth.
Sirius cried out in desperation, earning him a hard slap across his face.
“Moan as if you like it” Snape growled.
Sirius obeyed and moaned as Snape fucked his mouth hard.
“Yes, just like that...” he growled. “I was sure you knew how to put that mouth to good use, as the whore you are. Yes, take it all in, Black, suck me until I come in your filthy mouth... You like it, don’t you? Yes, you’re hard now… Touch yourself for me.”
Sirius wrapped his hands around his cock and began stroking it.
“Good…” he murmured as he kept fucking Sirius’s mouth.
And then, when he felt that he would soon be close to come, Snape forcefully grabbed hold of Sirius’s hair and pulled his head back, but not enough to let his cock out of his mouth.
“Look at me.”
Sirius looked at him, his eyes blank. Oh, he was a pathetic sight with his wide eyes and his mouth closed around his cock, unable to speak.
“Do you know how I’ve dreamed of this?” Snape hissed. “To finally shut up that mouth of yours, to see your lips close around my cock... On your knees before me, helpless and pathetic. You’ve lost, Black. I will never forget this, and neither will you.”
He thrust back into Sirius’s mouth, and Sirius moaned as he came over Snape’s shoes. Snape hit him hard in the face, and then, without warning, he thrust his cock down Sirius’ throat. Sirius let out a pained whimper, and Snape moaned at the sound of it. He buried his hands in Sirius’s hair, pulling forcefully as he thrust back inside. Sirius’s whimpers were growing louder, he tried to pull away, choking now. But Snape’s punishing hands held Sirius’s head firmly in place as he fucked that hot, unwilling mouth into submission.
“You asked for it” he growled. “You asked for it, and here it is, you...”
He cried out as he came hard down Sirius’s throat, and he pulled out just in time to let most of his cum shoot over his face.
“Now, lick my shoes clean” he ordered.
Sirius leaned forward to start licking his shoes, tasting his own tears mixed with his cum.
“Good dog” Snape said when he was done.
He pulled up his trousers and picked his wand up from the floor.
“Finite” he said, and the ropes loosened from Sirius wrists.
Snape kept his wand pointed at Sirius as he left, but the other man just sat there, staring blankly into space.
And then Snape left, and Sirius could hear the screams from his mother’s portrait.
“Filthy scum, shame of my blood! Blood traitor!”
He woke up with tears in his eyes, and he could almost taste the cum in his mouth. He realised that he had come in his sleep.
“No… God…”
He sat up and rubbed his face.
“It was just a dream…”
In the next moment, he had risen from the bed and rushed to the bathroom, where he threw up violently into the toilet. He could hear someone open the door outside. It must be Remus.
Thank God…
“Sirius? Are you all right?”
“Come in” he said with a half-choked voice.
He slumped down on the floor, resting his back against the wall as Remus came in.
“What happened?”
“I’m not drunk…” Sirius whispered. “Oh God…”
“What is it?”
“I had a nightmare… Snape… He used the Imperius curse on me. He raped me… It was so real…”
“My God, Sirius…”
Remus put his arm around his shoulder, leaning his head against him.
“He kept calling me a whore… He came in my mouth, and on my face… He told me that I liked it. And when I woke up, I had come…”
“Listen…” Remus finally said. “It can happen. The body can react in certain ways, even if you don’t want what is happening.”
“Really?”
“Really. Will you come to bed with me?”
“Yeah… I’m just gonna brush my teeth.”
“Sure. I’ll be waiting for you.”
When Sirius had brushed his teeth, he changed his underwear and his pyjama pants. Then he returned to bed and lay down beside Remus. He rested his head against the other man’s chest, and Remus gently caressed his hair.
“I’m so glad you came back” Sirius murmured.
“I’ll be here” Remus answered. “All through the night.”
