Work Text:
Tom Riddle was really very upset.
He'd never been interested in his classmates or anyone else before. But now? For crying out loud, what was so special about that Potter boy? Sure, he was Gryffindor's Golden Boy and the Chosen One and the Gryffindor Quidditch captain. But from his perspective, that meant nothing, and he didn't understand why he kept thinking about Potter. It was incredibly inconvenient.
He needed to concentrate. He had to focus on his studies and research projects. After all, you don't become top of your class by nothing. And his additional duties as Head Boy already took up enough of his valuable time—thank you very much! He was now in his seventh and therefore most important year of his schooltime. He had to graduate at the top of his class; this was crucial for the ministry position he had his eye on.
***
The Great Hall buzzed with activity. Tom sat at the Slytherin table, staring at the back of Harry Potter's head with burning eyes.
He had to get Potter out of his system.
As Harry stood up and left the hall, Riddle followed him.
"Potter, one word."
"What do you want, Riddle?"
"Not here, let's go into that classroom over there for a bit. It's not in use anymore and we'll have some privacy." With that, Riddle swept past him like a king on his way to an audience.
Harry grinned and followed him. He was very curious what the Ice Princess could possibly want from him. If he could catch a glimpse of Riddle's handsome backside in the process, all the better. Despite his arrogance, this bloke was quite a sight.
"I am going to do you a great honor today. You may accompany me on a date to Hogsmeade on Saturday."
Harry stared at Riddle, wide-eyed. Large, fascinating green eyes. Tom shuddered slightly. He was satisfied; Potter was obviously so thrilled by the idea that he was speechless.
Then Harry started laughing. The arrogant brick was quite serious and thought Harry was deeply grateful for this extraordinary opportunity. Well, he probably wouldn't be entirely opposed; Riddle had certainly caught his eye, as he had everyone else’s. But immediately his pride rose. Not so fast, Riddle.
"What's so funny, Potter?" snapped Riddle, irritated.
"You're hilarious, Riddle," chuckled Harry. "I have no interest in going on a date with you. Offer someone else that incredible honor." Harry smiled sneeringly.
With that, he turned around without a further word and prepared to leave the classroom.
Tom stood frozen for a second. He had never before stooped so low to ask anyone out. He knew exactly what he looked like and the presence he had. After all, everyone wanted Tom. He was the most eligible bachelor in the entire school. How dare Potter reject him, and so rudely at that? White-hot rage overwhelmed him. His eyes briefly glowed burgundy with anger, and without further ado, Tom had his wand at the ready.
"Imperio"
Potter froze when the curse struck him in the back.
"Come here, Potter."
Harry turned around and slowly walked towards Tom. He stopped in front of him and stared past Tom at the ground.
"You will now be a good boy and obey my commands. Kneel down."
Harry dropped to his knees and waited for further instructions. Tom locked the door and cast powerful privacy charms.
He unbuckled his belt and unzipped his trousers. Still furious, he glared at Potter.
"Open your insolent mouth; I have a better use for it."
Harry continued staring into space and opened his mouth. The sight already made Tom half-hard. Potter really did look good like this. Compliant and silent. He took his cock in his hand and stroked it a few times until it was fully erect. "You're going to suck me really good now. You're going to moan like the cheap whore you are and only stop when I've come in your throat. Then you're going to swallow everything I so generously offer you. Start now."
Harry did as he was told. He knelt closer to Tom and licked along the silky shaft. He took the tip in his mouth and licked off the drop of precum. Then he began to suck him seriously, making the most delicious sounds. Tom was so aroused he wouldn't last long. Potter was clearly a master at sucking cock and achieved just the right combination of pressure and depth.
"Such a good boy! I knew you'd be the perfect cockslut for me." He let himself go and thrust his cock deep into Harry's throat. He thoroughly enjoyed the gagging and the tears that streamed down Potter's face. Yes, that was what that handsome face with the incredibly green eyes was made for. For his personal pleasure!
After a few more deep thrusts, Tom came with a groan in Harry's throat. After composing himself briefly, he took a step back, cast a powerful cleaning charm over himself and Harry's face, and zipped up his trousers.
That was really good. If he'd known a blowjob could feel so good, he would have tried it much sooner. The tension that had tormented him before was gone, and he was sure he could now productively resume his activities.
"Stand up, Potter." Harry obeyed immediately and stood up.
"You will freshen up now and then continue living your boring life as normal. You will be at my service whenever I give you a sign, and you will never tell anyone about this." With these words, Tom left the classroom without looking back.
***
After a few days, Tom noticed he was feeling tense again. He had a first-year student deliver a message to Potter and summoned him to the empty classroom at the end of the school day. Potter arrived on time, and Tom was able to successfully relieve his tension.
This went on for a few weeks. At first, Tom found the arrangement very satisfying, but now the sloppy blowjob was becoming somewhat monotonous. He needed more.
"You'll meet me in the Room of Requirement at 11 p.m. tonight. Don't let anyone see you leaving the dormitory; I don't want anyone to get suspicious."
Harry didn't answer, as usual. But that wasn't necessary; he would follow his orders as always. Tom was very pleased with himself. He was a powerful wizard and could cast a powerful Imperius Curse. The spell wouldn't stop working until Tom explicitly wanted it to. And he liked it the way it was. He probably wouldn't lift the curse and alter Potter's memory until after graduation. Until then, he would enjoy having a willing slut at his disposal.

"Lie down on the bed and spread your legs."
Harry did as ordered. Tom stared at Harry's hole and licked his lips.
He remembered the book he had read and cast some protective and cleaning spells.
"Lubrico".
He moistened his fingers with the lube and inserted his index finger into Harry's tight hole. The lube made it go in quite easily, and once he had stretched the hole wide enough, he inserted a second and a third finger. Harry responded nicely, pressing himself against the fingers and letting out little, delicious moans that sent shivers down Tom's spine.
"On your knees".
When Harry turned around, he couldn't wait another second, positioned himself at the entrance and slowly pushed into Potter.
Oh God, it was so tight! He'd never felt anything like that. He briefly felt like he was going to faint and waited a few seconds to pull himself together. Then he began to thrust. First slowly, and then with more force. The feeling was incredible. He used Potter's hole with passionate thrusts and was completely unaware of anything except their moans and the white-hot lust. With one final thrust, he ejaculated inside Potter, and they both collapsed on top of each other. After a few minutes, Tom had recovered enough to cast the cleaning spells, get dressed, and left the room.
He felt deeply satisfied and gave Potter no further thought.
***
Unfortunately, this didn't last long. Potter kept creeping back into his mind. He now had to use him three or four times a week to maintain his focus on work. He usually let him come to the unused classroom or the disused girls' toilet on the second floor, which no one ever used. He wasn't proud of it, but he'd also had sex with Potter twice in a broom closet. It seemed as if the more often he did it, the more he needed sex. This was highly unwelcome.
And there was something else he found most unwelcome: the way he perceived Potter. Harry. For the past few weeks, he'd only thought of him as Harry. Tom had even started kissing him regularly. He used to find that disgusting. A revolting thought, exchanging bodily fluids through the mouth. Whenever he saw couples kissing, he had to look away in disgust. But not with Harry. Once he'd given in to the urge, he had to do it again and again. Harry had beautiful lips, made for kissing.
He jolted awake from his thoughts. Damn it, he'd been daydreaming about Harry again instead of paying attention in class. And he hadn't taken any notes again. Tom rubbed his tired eyes. What was wrong with him?
After class, the students left the classroom. When Harry walked past without even glancing at Tom, he felt a surge of anger. Tom was astonished that he wanted Harry to pay attention to him. He longed to run after him, grab his hand, kiss him in public, and show everyone that he belonged to him. Tom shuddered slightly; what ridiculous thoughts.
Salazar, something was terribly wrong with him. He hated displaying his feelings. He had to stop seeing Harry. Immediately.
***
The resolution lasted exactly two weeks. Tom was burning with longing. His cock became hard at the most inopportune moments. He needed Harry – desperately; he couldn't think of anything else.
He sent him a message and summoned him to the Room of Requirement at 11 p.m.
Riddle had been pacing nervously around the room and practically pounced on him when he arrived right on time. He pulled him into a tight hug, desperately trying to smell at Harry's neck. He sighed deeply and trembled slightly. He smelled so incredibly wonderful, of sandalwood and leather. He really had missed him, he realized utterly bewildered as he slowly undressed Harry.
The sex was different this time. Tom wanted to prolong it and savor Harry as long as possible. He had kissed and touched Harry all over to elicit those beautiful moans. Then he had made love to Harry, kissing him continuously. Afterward, he hadn't felt the slightest urge to leave immediately. He snuggled up to Harry, kissed his shoulder, and murmured softly, "Harry, you're so good to me." Then he closed his eyes, relaxed, and they fell asleep together.
The next morning – luckily a Saturday – he kissed the still sleeping Harry on the forehead and left him reluctantly.

Professor Lupin clapped his hands.
"Please sit down, we're about to begin the lesson. Starting today, we'll be studying the Unforgivable Curses. This curriculum will – at least in theory – also be an important part of your graduation exams. Who can tell me the curses and their effects? Yes, Mr. Riddle."
"The three Unforgivable Curses are the Imperius Curse, the Cruciatus Curse, and the Avada Kedavra Curse," Tom began calmly. "The Imperius Curse, also called the Control Curse, deprives a person of control over their actions and forces them to obey the caster's commands. The Cruciatus Curse is a torture curse that causes extreme pain without necessarily leaving physical marks, and is therefore considered particularly cruel. Avada Kedavra is the death curse and leads to instant death."
"Correct, Mr. Riddle. Take 10 points for Slytherin. Who can tell me what the most essential difference between the curses is? Yes, Miss Granger."
"The most essential difference – apart from the obvious, of course – is that the Imperius Curse can be resisted. This requires extremely powerful abilities. But it is impossible to escape either the Cruciatus Curse or the AK Curse."
"Correct, Miss Granger. 5 points for Gryffindor."
The classroom became louder. The students looked at each other doubtfully.
"You don't believe it's actually possible? In fact, I know very few wizards who can resist an Imperius Curse, but I know a way to convince you. Harry, could you please step forward?"
Harry stood up and walked across the classroom. Tom stared after Harry, puzzled; what was Lupin up to?
"Our Mr. Potter here, as you know, is a special wizard who has been involved with the machinations of the Dark Lord Grindelwald for several years. Harry, may I cast the Imperius Curse on you?"
"Of course, Professor, no problem." A horrified murmur arose in the classroom.
"Imperio".
All the students watched wide-eyed as the silver-golden curse struck Harry in the chest. Harry's eyes briefly glowed with an unnatural shade before the light faded.
"Harry, hop around the classroom on one leg."
Harry didn't move, smiled, and simply said "No!".
As the entire class erupted in applause and cheers, Lupin smiled and said, "As you can see, it is possible. However, I must warn you. Please remember, it is only possible for the most powerful wizards, and it is absolutely forbidden to cast the curse, not even for experimental purposes. Therefore, never try it. Curiosity isn‘t worth to go to Azkaban. Okay, thank you, Harry, you can sit down again."
As Harry walked back to his seat, he looked directly into Tom's utterly stunned face, grinned slightly and winked at him.
