Harry was sitting in another boring DADA class, waiting for it to pass. Although, it wasn't entirely boring, every hour he'd stare at his teacher — Tom Riddle, not to mention they had been seeing each other for quite some time now. Of course, they kept it hidden. Student-teacher relationships were forbidden, but they couldn't help themselves. There was something about Tom and Harry that kept pulling them together, like force.

Harry admired the way his big, veiny hands pushed his dark curls back, and the way his jaw clenched whenever he talked. Harry was too caught up in his own world, that he couldn't even hear him calling him. "Potter, stop daydreaming in my class," he ordered and slammed a thick book on Harry's desk, startling him. "Sorry, sir," Harry rolled his eyes at him and crossed his arms, slouching in his chair. Riddle huffed and sat back down at his desk.

"Fix that fucking attitude of yours,"Tom heard Harry's voice in his head — Legimallacy.

"No," he spoke back to Harry, both glearing eachother down.

"We'll speak after class, slut," Harry ordered, and Tom nodded imperceptibly.

Class has been dismissed not even 10 minutes after their conversation. Harry slowly packed his things back in his book bag, waiting for the other students to leave. Tom was still sitting at his desk, a book in his hands. Harry walked up to him and stood in-front of it, his hands connected with each other behind his back, straitening himself up to his full height. Tom looked up from his book and placed it on the desk before him. "Bend over," Harry ordered.

"I'm not gonna bend ov—" Tom started but Harry cut him off as he walked around the desk, "I said. Bend. Over. " He growled, Tom obeying this time. He bent over his large desk as Harry walked to his side, standing behind him. Harry pressed his front to Tom's back so he could feel the erection against his ass, making him let out a low moan.

Harry chuckled behind Tom and pulled down his fancy dress pants he was wearing that day and sent a smack to his arse. Tom whimpered as the hard smack hit him again, "You enjoy this don't you, pretty boy?" Harry whispered in his ear sending shivers down his spine. "Y-yes," The professor answered him and Harry smacked his bum one last time before grabbing a fistful of his hair, yanking his head up, "You're gonna be a good pet for me and keep quiet while I fuck you in this classroom, aren't you?"

"Yes sir," Tom moaned as Harry pushed his tight fitting boxers down and stuck a finger in him. Tom bent down again, while Harry was replacing his finger with his tongue, so he could have more access to his hole. Harry's tong worked wonders on Tom making him grip the edge of the desk - his knuckles turning white - to suppress moans that were about to escape. Tom arched his back in pleasure and a loud moan left his mouth - but he quickly covered his mouth with his hand.

Tom let out a whimper as Harry's tongue left his, now wet, hole, "I told you to be quiet didn't I?" Harry growled and flipped Tom over so his back was against the desk. Harry unbuckled his belt and pulled his erect cock out. He teased Tom's entrance with the tip of his cock making Tom even more desperate to be filled with him.

"Hades please," Tom begged. Harry softly slapped Tom's face and grabbed his jaw with his hand, "I told you not to call me that anymore fucking desperate slut," he whisper shouted.

Harry looked so fucking hot while mad.

Well he's always hot.

Without warning, Harry pushed himself into Tom and started to thrust in at a high pace. He brought a hand to Tom's dick and stroked it at the same pace. Harry loved seeing Tom fall apart beneath him, it was the hottest thing he could ever witness. His eyes scanned Tom's body, a smirk lingering on his face the whole time. "You look perfect like this," he growled and hit Tom's prostate bringing the man closer to his orgasm, "Fuck, right there," Tom moaned and Harry hit it again and again and again.

Tom was on the verge of cumming and surprisingly Harry let him, " ," he ordered as he felt Tom's walls clench around him. Tom came. Hard. His cum splattering all over his stomach and chest. A few hard thrusts later Harry came himself, burying his dick as deep as he could. He threw his head back and his mouth was parted a little.

Harry pulled out and cleaned Tom, then himself and helped the man of the desk , casting a cleaning charm on the desk. "That was amazing," Tom panted, still coming down from his orgasm. "Yeah it was."
