Chapter Text
Sirius was looking down to the drink in his hand, feeling extremely bored. Another one of Professor Slughorn’s dull dinner parties had gone on for hours at this point, and there was no escape in sight. Even James has let him down as he had not attended, being the busy quidditch captain and all…
Sirius himself could have skipped is he had wanted to. Call it pride or egoistical, but he did quite enjoy the idea of being in a group of selected few. Especially since the invites are not about his heritage, but rather his academic achievements. Or at least that’s what he likes to tell himself. It’s not like Remus had been invited, despite being top of their class for several years now.
So, here he was, trying to enjoy his dessert with the most mundane company he could imagine: all the worst swots in Hogwarts and of course, their ”lovely” professor. Looking around the table, Sirius couldn’t point one even one person he actually wanted to talk to. But of course he was polite and played his part in the conversation.
The evening was coming to an end, Sirius’ glass now empty in his hand. The attending students all went around thanking Slughorn for having ”once again hosted a great dinner”. Sirius could hardly keep himself from rolling his eyes at them, as he too rose from his chair and started towards the door.
”Sirius, will you stay behind for a minute?”, Slughorn asked and Sirius had to turn back around. All the other students went ahead, leaving the two alone.
”Uhh, sure, Professor”, Sirius answered. He hoped this didn’t have anything to do with the prank he and James had pulled on some Slytherins the previous week…
”Don’t worry, I just wanted a little chat with you. That’s the downside to big dinner parties, you can never talk enough with anyone! Now, please, take a seat”. Slughorn guided Sirius to a sofa in front of a fireplace.
”Drink? You know I usually can’t offer alcohol to students, but I have seen you with the champaign in your parents parties, so I think it’s fine”. Slughorn said with a knowing wink. He was fussing around his vitrine with different drinks in it.
Sirius was a bit taken back at the mention of his parents, but decided not to let is bother him.
”Sure, it’s fine”, he answered. There was a glass of red wine in his hand in no time. He took a sip, planning to drink it fast so he could be on his way out sooner.
”I’m sure you can appreciate this, great vintage from France. Isn’t your family from there, originally?”, Slughorn questioned, a wineglass in his own hand, sitting on the other end of the sofa.
”Yeah, you’re not wrong… We still have a summer house in there”, Sirius said, annoyed about the inquiries about his family. Like he gave a toss about their French roots.
”How wonderful! I’ve been myself a few times, not lately though. Life gets on the way, eh?”, Slughorn went on rambling about.
Sirius took another gulp, feeling the warmth of the alcohol filling his body. Now that he thought about it, he was feeling quite sluggish already, which was extremely weird from just one glass of wine. He hoped Slughorn would just get to the point already.
”Was there something you wanted to talk about, Professor? Is this about the other week? Because McGonagall already….”
”Oh no, don’t you worry Sirius. That’s all water under the bridge”, Slughorn waved his hand in a dismissing manner.
”Then what is it?”, Sirius urged, now starting to feel the slurring of his words. His whole body felt relaxed and… weirdly pleasant. Had he really got that drunk? He started to question his tolerance, since they hadn’t thrown a party for a couple months now…
”Well, Sirius…”, Slughorn started, setting his own glass on the side table and moving closer to Sirius on the sofa. Sirius started to think that maybe there was something even more grave than the prank…
All of his speculating thoughts came to a halt when Slughorn placed a hand on his thigh. He hadn’t even realized how close the Professor had came.
”What the…”
”You know the rumors that go around about you? I’m a teacher of course, but I have my ways… Quite the ladies man, aren’t you?”, Slughorn said tentatively.
Sirius stared down in horror as Slughorn moved his hand slowly towards Sirius’ crotch. He felt disgust ing, horrified, absolutely repulsed… but also… he felt the warmth in his body get more intense as the hand got closer to his private parts.
”Wh-, whaat iss thiss?”, Sirius slurred, still in a horrified shock of the situation.
”I’m a potion master, aren’t I? You’re a smart boy, you must be able to figure it out”, Slughorn stated, now with an evil sarcasm in his voice.
Absolute terror came over Sirius. His mind was moving slowly, but he was indeed smart and could put two and two together. Whatever had been in that glass, it wasn’t just wine.
The shock started to subside and Sirius was able to move once again. He started to rise from the sofa, but found his legs extremely wobbly and his head dizzy. He got maybe two steps away as he felt Slughorn’s hands on him.
”Tut tut… There’s no need for such hurry, Mr. Black”, he scolded. He had grabbed Sirius from behind, one hand on his shoulder and another around this chest. Sirius, in his disoriented state, couldn’t get away even if the wanted to. He could barely stand on his feet.
Slughorn took advantage of his position immediately, bringing his mouth to Sirius’ neck. He breathed hot air and started to suck and bite on the sensitive skin of the neck. Sirius felt horrified at first, but it slowly melted into lust. He could feel the warmth in himself multiply, a common tingling starting to form down there…
”Mmhh..”, a small moan escaped his lips as he was preoccupied with the sensations. Slughorn only chuckled.
”Like that, don’t you? The potion is proving to be much more effective than I expected..”, Slughorn said to himself.
Next he moved his hand from his shoulder to his neck, undoing the clip of Sirius’ cape in on swift movement. The cape fell to their feet. After that, his hand continued its way to Sirius’ stomach, continuing downward from there, trailing his fingers across Sirius’ fit form. Sirius sucked in a breath as Slughorn’s hand finally reached his trousers, groping him over the fabric. Sirius was instantly filled with pleasure, rubbing himself to Slughorn who was still standing behind him.
”Oh boy, you’re getting me hard…”, Slughorn sighed, now grinding himself against Sirius’ butt.
”Please…”, Sirius gasped, feeling his own arousal and also Slughorn’s, growing hard against him. He didn’t know if he was begging for it to end or to continue. He still held onto the knowledge that he didn’t want this, that this was horrible and wrong, but his entire body thought otherwise. His mind was losing the battle.
While he was lost in these thoughts, Slughorn had subtly maneuvered Sirius back towards the sofa.
”Here, boy. On your knees”, Slughorn guided, and Sirius could only comply. His legs gave out the moment Slughorn let go of him, falling to his knees in front of the sofa. Slughorn himself went around him and sat on the sofa, looking extremely pleased with the sight in front of him.
”Now Sirius, I expect you know what to do..”, Slughorn said suggestively, opening his own pants, and pulling out his penis. Sirius wanted to turn away, wanted to get away, but… he was still aroused, and the lust drew him to bow over Slughorn’s lap hesitantly.
As soon as his head was within the reach of Slughorn, he grabbed his hair in a fist and pulled him down towards his fully erect member. It filled his mouth and throat, and he felt himself choking right away. Slughorn’s hand guided him firmly, up and down, up and down…
”Just like that, you pretty boy”, Slughorn whispered into Sirius’ ear.
Sirius’ body felt like fireworks, like this was his purpose all along. He sucked hungrily on Slughorn’s dick, not being able to get enough of it. He had never done this before, obviously, but he has done some experimenting with Mary... But this was completely different, and a million times better.
Slughorn started to let out voices of pleasure, moaning loudly at the sensation. His grip in Sirius’ hair tightened, making is hurt. At the same time he increased the tempo of movement, pulling Sirius’ head down faster and faster. The chocking sensation grew more intense and Sirius could feel his eyes becoming teary, fiting back the urge to throw up.
Suddenly, he felt a surge of liquid at the back of his throat, and the hand in his hair released its grip. Sirius fell back slightly. He was retching, white slime dripping from his mouth. Slughorn leaned back, breathing heavily.
”Oh my… You are a wonder, boy…”, he gasped.
Sirius was dumbfounded. It was like he was in a trance, that was clearing up a little bit now that there wasn’t a dick in his mouth. What the hell just happened?!
”I.. I think I ha- have to…”, he stammered, starting to crawl away of the sofa, still not trusting his legs.
”Now, now Sirius. This was just the appetizer. I’m sure we can come up with other things to do before you hurry out”, Slughorn smiled a sinister smile as he rose from the sofa, walking slowly towards Sirius. His pants were still open, dick hanging out loose.
Sirius crawled backwards, his moment of clarity filling up with dread. His breath caught in his raw troath.
”Please… Please don’t do this. I p- promise, I won’t tell anyone”, Sirius pleaded desperately.
”Oh, I know you won’t”, Slughorn stated. From the ground Sirius realized how big of a man Slughorn actually was. Even without the potion, and his experience with magic, Sirius wouldn’t have a chance against him.
In one fast motion, Slughorn bent down, grabbed Sirius from under his arms, and lifted him. He walked them to the dining table, pushing Sirius to bend over it, his face towards the table. Slughorn was standing right behind him.
”And now for the main event…”, he chuckled, using his feet to open Sirius’ legs wider. A horrifying realization took place in Sirius’ mind, at the same time as his body filled with warmth once again.
Slughorn opened Sirius’ pants, pulling them down fast.
”Please, please Professor…”, Sirius choked out. He was struggling, trying to pull away from the table, only to feel Slughorn’s penis press against his ass.
”Hush now, play nice”, Slughorn said as he pushed Sirius more firmly against the table, taking once again hold of his hair. Sirius felt his face being pressed against the cold mahogany.
Sirius knew it was coming, but he still shouted out when he felt Slughorn’s dick press into his ass. It felt tearing and painful, not like any other pain he had felt before.
But it also felt… filling. Satisfying…
Slughorn started slowly, pressing himself inside Sirius in firm, deep thrusts. He had a strong grip of Sirius, other hand in his hair, keeping his head down, and the other on his hip, bruising it. Sirius felt heat. It filled him from the inside, with every thrust becoming more intense. He was letting out gasps, the pain turning into lustful pleasure as he was pressed hard against the table, being completely unable to move.
”Professor… Yes, please, hnggh…”
”Yes, take it like the little slut you are. You little bitch, begging for more…”, Slughorn moaned as he pounded inside Sirius with force.
”You pureblood bitches are all the same. You’re not my first, of course. I have quite the collection already… So tough, but once I get my hands on you…” Thrust, ”You”, thrust ”always”, thrust ”submit”, thrust.
Slughorn picked up the pace, pounding into Sirius harder and faster. Sirius was almost delirious from pleasure, whining and moaning, not paying any attention what was being said above him. He felt the semen mixed drool dripping out of his mouth to the table as he moaned.
Slughorn was not pounding with all his might, and Sirius was losing his mind. He was close, so close…
”Aaahhh!”, he moaned loudly as he came, pushing Slughorn over the edge at the same time. He felt his insides fill with a warm liquid, as Slughorn stopped pounding and leaned over Sirius, breathing heavily.
Sirius felt like his brain had exploded with pleasure. He felt high, warmth still filling him, as he lay on the table. But that wasn’t going to last. Slughorn was done, so he pulled his dick out of him. Sirius was left with an empty, almost hollow feeling. He could feel the semen dripping out of him, as he lay limply on the table.
”That wasn’t so hard, now was it?”, Slughorn said, satisfied, as he closed the buttons of his pants.
”It’s late, so I must get going. Take your time, but close the door as you leave, would you?”, Slughorn asked with exaggerated kindness in his voice. It sent shivers down Sirius’ spine. The professor leaned over Sirius.
”I have to say, you are such an obedient little plaything… A great pleasure, for sure. I wonder if your brother would be as good… I do like a set”, Slughorn whispered into Sirius’ ear.
All Sirius could do was stare ahead in horror, as Slughorn walked away, leaving him alone, defiled and molested.
