A Lesson He'll Never Forget

Note: This story has been edited and revised. It is now separated into sections instead of written in para rp format. I hope it’s easier to read now. Enjoy.

Fred was sitting in his usual seat in the potions classroom next to his twin brother George. Every time he had to look at his professor, he would gag and think back to what he had done a few months earlier. True, Severus had raped George and Fred had gotten revenge the only way he saw fit, but he still felt there may have been another way to avenge his brother.

The main reason he would gag, was not because the thought of touching Severus made him nauseous, but because he felt that familiar flutter and his groin would stir when he thought about his potion’s master in a sexually compromising position. He pushed the thought far from his mind when he heard his twin speaking to him.

“Fred, you alright?” George had been worried about his brother since that day when he had left Severus’ classroom and had refused to tell him what had happened.

He sighed and shook his head. “Nothing, George. I was just thinking about Snape.” He was quite surprised that he had admitted it out loud when he had yet to admit it to himself.

George was floored. He had never thought his brother would be interested in a man, let alone Professor Snape. He himself had some feelings for the man before he had been raped by him, and although he shouldn’t, he still had feelings for him. Truth be told, he would give just about anything to be in the man’s bed even after what he had done.

He chanced a glance at Severus, wondering what his acidic potion’s master was thinking at that moment.

|o|

Severus had been plotting and planning since the afternoon Fred had paid him a visit. A smirk had crossed his lips as the boys had entered the classroom. He was fantasizing about them both during the whole class, just like every day since.

When no one was paying attention, he closed his eyes and leaned back, letting his hand brush lightly over his growing erection which was trapped in his tight pants. The boys had no idea what the thought of them did to him and having them in such a close proximity made it even worse.

His mind was working in overdrive throughout the whole class. He had given the students an assignment to read their potion’s text and write a foot long essay before the end of class. In any case, he wouldn’t be bothered in his day dreams. He could just sit there and imagine how amazing it would be to be between the two writhing bodies of the muscular Weasley twins.

His head snapped up and he caught George’s eye. Immediately he was determined to hold them after class that day and show them just how much their very presence tortured him. But he had to find a way to get them to consent.

The first time was different. He had been lucky that the boys hadn’t said anything to Dumbledore. But he couldn’t chance that they would keep quiet if it happened once more. Severus’ lips curled into a smirk as the plot began to form in his head, nearing the end of their potion’s lesson.

|o|

George tapped his brother on the arm when he saw the look on the Potion’s Master’s face. “Fred. That’s the same look he had on his face the day he ‘held me after’. What are we going to do?”

He was anxious because he was looking forward to showing Severus how he really felt about him, but he wasn’t sure he should. What if Severus didn’t have feelings for him at all and he was just there to fuck..? He was so confused that he was visibly shaking.

Fred looked to his twin and rubbed his back slightly. “Don’t worry, George. Everything will be alright. Maybe this time it could be different.” Fred had a smirk on his lips when George looked at him.

He had no idea his brother would have feelings for their Slytherin professor. He had been hoping, but he never got what he wanted. Over the past few months, Fred and George had been experimenting with each other and had decided that the only way to prevent each other from getting hurt was to just be together.

They had a love deeper than brothers. And once Fred had realized he’s gay, it went a lot smoother. So here they were. The Weasley twins in a relationship, but both of them lusting over the one man who had hurt them.

George’s eyes lit up as a thought occurred to him. “Fred. Do you realize that Snape is what brought us together? If it hadn’t been for him, we never would have realized our feelings for each other.”

The smirk was now on George’s face. He had been quite reserved since the rape, but lately he was beginning to open up again.

It was now Fred’s turn to be skeptical. “Right, but how do we get him to see it that way? And what are we going to do once we get him alone?”

The twins sat there thinking about it until Severus dismissed them. Now was the time to carry out their half formed plan.

|o|

The professor was lost in his fantasies when he realized it was time to dismiss the class.

“You are all dismissed. I would like you to read the next 5 chapters and write another foot and a half of parchment by next class.”

He looked down at the papers on his desk to avoid watching the two objects of his fantasies walk out the door. The Slytherin longed for them to stay behind, but he had no way of asking them to without suspicion.

When he looked back up a few minutes later, they were standing in front of his desk with identical smirks. He was shocked and speechless. Finally, he got himself together enough to speak without his voice betraying the nervousness he felt within.

“May I help you, Mr.’s Weasley?”

He tried his hardest to look anywhere but at them and was failing miserably. They had removed their outer robes and their skin was practically begging to be touched. It was all he could do to prevent his hand from reaching out to smooth over the muscular, freckled skin up their arms. He caught their eyes, wondering what the boys could possibly want.

“Is there something you didn’t understand about the assignment? How hard could it be to understand reading five chapters and writing an essay? Or is that the infamous Weasley wit?”

His tone was biting, but he couldn’t exactly sit there and tell them what he really wanted to say and do. All he could do was wait for one or both of them to answer.

|o|

When the class was dismissed, the twins stayed behind. They took off their outer robes and laid them over the back of a nearby chair. If they were going to do this, they had to use every advantage they could. All doubts they had disappeared as they stood firmly before his desk, waiting for him to look up.

“Why, Professor, we’re here to speak with you,” Fred said, answering the obvious question.

“Yes, but our wit has nothing to do with it,” George finished.

They were going to do this and they couldn’t back out now. Fred reached his wand over his shoulder and muttered a charm, causing the door to slam and lock. He chuckled slightly at the shocked look on his professor’s face.

“Did you expect us to not pay you back?” Fred said.

George looked quite smug and muttered another charm, sound proofing the room. “Mmm, we’ve been thinking about you a lot, Professor.”

George walked around the left side of the desk and Fred walked around the right, trapping him behind it and in between them.

“I seem to remember you saying something about wanting to see me again after last time.” George leaned in and nipped at his neck playfully, causing Severus to close his eyes as he took in a sharp breath.

“I believe my brother is right, Professor. Don’t you want to see us?” Fred said then followed his brother’s example and leaned in, licking Severus’ ear and cupping his erection. “Oh my, you are a big boy, aren’t you?”

Fred smirked at George who nodded then pushed Severus down in his chair. He climbed into his lap, straddling him and ground into him slightly, eliciting a soft moan from between the man’s lips.

“I think he’s enjoying this, Fred,” He said then looked up at his brother and pulled him down, their faces barely inches apart.

“I think you’re right, George. Shall we help him enjoy it more?”

The twins began to kiss, George grinding into Severus as his tongue duelled with Fred’s, while Fred reached down to tweak one of Severus’ hidden nipples.

|o|

Severus sat there, utterly shocked. He couldn’t believe his fantasy was actually coming true. The man couldn’t even move as the boys closed in on him from both sides, and when they began to touch him. He almost came in his pants right there. George sitting in his lap and grinding into him really wasn’t helping any. If he were any more aroused, he’d be in pain.

His eyes went wide as the twins began to kiss and a hand snaked over his chest to tweak his nipple. The grinding continued from George and he put his hands on the boy’s hips, letting his head fall back as he groaned.

He had dreamed of this day, but he didn’t think he would be able to handle it if it were just a trap or a cruel joke. When he realized that it could in fact be a prank, he stopped them.

“Boys, as much as I would like for this to continue, are you sure you want to do this? Or is this some sort of cruel joke?” He would be furious if it were a joke and he would have to do everything to keep himself from killing them.

His only hope was that they wanted him as much as he wanted them. The thought had never really occurred to him that they had planned this because they were aching for him. It was more than he could have hoped for. Severus was worried it was all a trick.

|o|

When the twins broke apart to answer him, they couldn’t help but smirk.

“Severus, we have wanted you for quite a while now,” Fred said. They had always been able to finish each other’s sentences.

George nodded. “He’s right, Severus. We just couldn’t figure out a way to get you alone long enough to tell you how we feel.” The boy leaned in and brushed his lips across Severus’ while his brother watched with hungry eyes.

George could no longer hold back. He crushed his lips against the potions master’s lips in a bruising kiss. He moaned softly as some of the sexual tension began to release, only to be replaced with stronger feelings of lust.

Fred pulled him back and replaced George’s lips with his own, forcing his tongue into the professor’s mouth as his twin continued to grind. They were moaning loudly and getting even more turned on as the moments passed.

Fred broke the kiss and grabbed Severus’ hand, placing it between his legs and smirking when the man’s eyes went wide from feeling his bulge. “Do you still think it’s a prank, Severus?”

George leaned in and began to suck on Severus’ neck, rubbing his trapped erection against his professor’s. They were hot for him and there was no way around it. They would have him, their plan would work, no matter what, or he would regret it.

|o|

He was taken by surprise when they began to kiss him. It was his fantasy. Possibly too good to be true. He shut his eyes tight and hoped that it wasn’t a dream. He heard them moaning and knew he was moaning as well. Hell, he couldn’t help it; these boys were too damn hot and good at what they do.

When one of them pressed his hand to their groin, his eyes shot open. Severus could no longer fight it. George was sucking on his neck and grinding into him as his hand began to massage Fred’s erection. He carefully lifted George into his arms and took Fred by the hand, leading them to his private bedchambers.

He laid George on the bed and with a quick flick of his wand and they were all naked. The twins grinned as he lay on his back next to George, giving them full access to whatever they planned to do with him.

Slowly, Fred climbed to Severus’ other side and the twins set to work. Licking, biting, sucking and pulling on his nipples. They moved to his neck and began to give it the same treatment as his nipples, while fingers lazily played with the sensitive nubs. He moaned and lifted his hips off the bed, wanting contact.

The twins had been careful to avoid touching his cock and it was swollen with need and want. He was dying to bury his hard cock inside one of them and have a cock stuffed up his ass as well. He was quite the wanton slut.

|o|

Fred and George were having the time of their lives with their potions master. He was like putty in their hands. Their minds failed to process any coherent thoughts when Severus had led them into his bedchamber and proceeded to undress them.

After lying on either side of him, they took much pleasure in showing him just how much they wanted him. Even as they teased him, they were becoming painfully hard, aching to touch and be touched.

Fred looked up over Severus’ chest and gave George a knowing glance. George nodded, and with little effort, flipped Severus onto his stomach, lifting his hips slightly. Fred opened a drawer next to the bed, hoping beyond hope that the greasy professor kept some sort of lubricant in his rooms, not that he deserved the thought after what he had done to George.

When he had finally found what he had been looking for, he handed a small vile to his twin, a wicked smirk painted on his lips. Without a second thought, the boy coated a finger and slipped into his professor’s tight arse, gently letting him know he would be treated with a kindness he had not previously bestowed on the young Weasley.

Relishing in the moans of desire that he pulled from the older man, he slowly worked in another finger, all the while watching Fred tweak a nipple on the man before him. Fred coated his finger as well, then turned Severus’ face so he could watch while he prepared himself.

One thing they knew for sure, they would enjoy this as much, if not more than, their snarky potions master.

|o|

Severus could not believe the amount of pleasure these young men were showing him. After what he had done to George, and the previous manner in which Fred had treated him, it was an unexpected surprise. Not one he would turn away or take for granted.

As the first finger pressed into him, he couldn’t bite back a moan, knowing they were enjoying seeing him beg for more. Fred’s fingers were nimble and knowing as they worked his nipples, turning them into points of undying pleasure.

As Fred turned his face and he saw the vile in the boy’s hand and a coated finger, his eyes glazed even more and passion almost overtook him. He watched with great pleasure as the red head reached a hand around himself and began to prepare his tight hole.

Though he had hoped, he was quite surprised that he was going to be able to penetrate the young man; at least he hoped that’s what the boys had in mind. He let his eyes roll back at the sight of Fred moaning and moving his slender finger moving in and out.

George hadn’t once stopped his movements behind him and had added yet another finger. Before he knew what was happening, the boys had lifted him to a kneeling position. He opened his eyes to look at them questioningly.

They winked at each other as Fred took his place before Severus and bent over. Never, in all his wildest dreams had he ever thought he would be in the middle of the Weasley twins, and he had dreamt about it often.

All he could do was hope that this wasn’t a dream; he didn’t think he could survive this if it was.

|o|

When Fred moved in front of Severus, George began to slide in a third finger. He wanted Severus to enjoy this as much as possible. The red head in front of the older man looked back over his shoulder at his twin as he guided the potions master’s hand down between them and prodded him to replace his fingers with is own.

Fred bit his lip and moaned as Severus moved one, then two fingers in and out of him, muttering about how tight he was. George couldn’t hold back a moan as he brushed up against the older man’s prostate, causing him gasp and push back onto the hand penetrating him.

The boy smirked and moved in and out slowly, brushing it a few more times before he removed his hand and gently stroked his already hard cock at Severus’ entrance. Fred was impaling himself on his professor’s fingers, begging for more as his brother slowly inched into the man’s arse, soliciting a soft groan from deep in his throat.

Speaking in a low, passion filled voice; George declared his undying love for the tight hotness he was plunging into. He knew Severus preferred men, but he hadn’t known how often he hadn’t gotten laid. He had most definitely been dreaming of the day he would take his potions master.

His twin was writhing and moaning in front of the dark man he was about to fuck, wanting to feel Severus inside him. Fred gasped and moaned low as Severus did just that, moving slowly into his young student as the boy’s twin continued his torturously slow entrance.

|o|

The Slytherin was in pure heaven, one Weasley twin penetrating him and the other waiting to be penetrated. Without a second thought, he removed his fingers and began to slowly move into Fred, groaning and desperately trying not to cum too quickly.

Although he was much older than the two boys, he had excellent stamina and knew he could last, then go again if need be. The feeling was extraordinary, being filled while filling someone else. He knew he could set the pace while impaling the young boy before him then move back onto the one behind him, or he could let George take control and let him slam into his tight arse while forcing him to slam into Fred as well.

He placed one hand on Fred’s hips and another on George’s, holding them stationary while he moved in between them. The decision came instantaneously; he would love to have it rough, but he figured it would be amazing to move off one and into the other. As far as he could tell, the Weasley twins were also looking forward to the course of action he was taking; neither of them fought to gain control of the pace and they were moaning quite loudly.

Slowly, after having George fully inside him and easing into Fred, he began to move back and forth. He pulled off George’s cock and pushed into Fred, moving his hand from the boy’s hip behind him to join his other hand on the other hip of the boy in front of him. He let his eyes roll back as a steady, slow pace was set.

|o|

Both of the twins were confused at first. They had though that Severus was just going to let one pound into him and therefore cause him to pound into the other. Fred and George had expected to set their own pace, hard, rough and deep. But they weren’t upset with the pace their professor had set.

All the many times they had spoken about this moment, they had never assumed he would be so ready to accept their offer; though they had hoped. All in all, it was looking up for all three of them. And in the middle of it all, was their loathed potions master. His greasy hair, his sallow skin, and his beaked nose. They had been attracted to him for reasons unknown to even themselves. The twins both knew they could get him, but they hadn’t accounted for him giving in so easily.

As Severus began to speed up, both boys moaned louder and got closer to climaxing. Neither George, nor Fred, had experienced anything as wonderful as having someone move in between them, using one to propel himself into the other. Fred almost lost it when he felt a hand snake around his waist and firmly grasp his hard cock, stroking it with fierce passion.

|o|

In an overload of senses, he barely noticed them speed up slightly, all three moving as one. As he drew closer to his own climax, he reached around to be sure to bring Fred off as well. He angled slightly as he grasped the leaking cock, hitting the boy’s prostate with each thrust.

Reaching back with his free hand, he moved George deeper inside him, causing them both to thrust at the same time instead of Severus just moving in between them like he had been. He began to lose himself in all the pleasure. He had let them into his bed, and seemingly into his heart as well. Though, this would have to be kept secret. Severus couldn’t exactly let Dumbledore know he was fucking students, let alone twins and at the same time. A

small smirk came to his lips as he could imagine the look on the headmaster’s face if he were to ever find out, but the thought was swiftly pushed far from his mind as he was brought back down to earth in just enough time to feel Fred arse tighten around his cock. He knew the boy was close and when he climaxed, it would cause a chain reaction between the three.

Severus just hoped it wouldn’t end too soon, but the pressure building in his balls was almost painful, and he begged for, yet cursed, his release.

|o|

As their professor drew near his own release, they also closed in on theirs. Mutually, they could feel it. They had a bond which went beyond just being twins. What their mother didn’t know about what went on behind their closed door couldn’t hurt them. They had to get their experience somewhere, and who better to learn about your sexual preferences than from your own, personal twin. A mirror image of yourself.

Moaning, they moved faster, Fred pushing back and impaling himself on his professor’s cock harder than before as George slammed into the greasy potions master’s tight arse. The world stopped spinning for a few moments as they all felt it simultaneously.

First Fred came, his arse clenching around Severus’ cock which was buried deep within him. That caused Severus to thrust deeper and harder, a few more thrusts, and he was coming deep in Fred’s arse. His arse began clenching around George, who in turn thrusted a few more times and came as well.

The three of them fell sideways, still connected to each other and sweaty as well as sticky. They lay there for a few minutes, when Severus disconnected them and removed himself from the tangled limbs on the bed.

|o|

As he stood away from them, he gathered his clothes and began to dress. He was having second thoughts, unfortunately for him they were forming in his mind after the fact. He shook his head muttering about ‘headmasters’ and ‘board of governors’. Severus knew his job would be on the line if anyone were to discover that this had happened.

He sneered and looked down at the red heads in his bed. “Get up. Get dressed. Get out.”

He was more than a little ashamed that he had let them take advantage of his desire like they had. True, it had been a very long time since he had been with someone, but it had been a huge mistake to let the twins be who he gave into.

His inner voice laughed when he thought about the one person he had always thought would have broken him down before anyone else. Potter… Of course, the boy was straight, as far as he knew, and most likely had no interest in him whatsoever.

He picked up Fred and George’s clothes, throwing the robes to the boys and hoping they would quickly and discretely leave.

|o|

The twins lay there wide eyed and naked as their professor disentangled and stood. Sharing a look and shrugging, they began to move to get up. Fred and George had figured this would happen.

They had no doubt he would let it happen, but somehow had known he would act this way afterward. From both of their previous encounters with him, they knew he would throw their clothes at them and tell them to get out. And, of course, he did.

Their robes hit them in the faces and the twins hurried to dress as quickly as possible. The sooner they got out of here, the sooner they could relive this experience with each other behind the drawn curtains of a four poster bed back in the dormitory.

Smirking, and quite obviously, they stood and walked over to Severus, kissing him on each cheek simultaneously then walking out of the door to the corridor. Having not given their professor a chance to say anything else to them had given them a slight upper hand in the situation. He hadn’t told them not to say anything to anyone, and they could blackmail him into another encounter.

All they had to do was wink at each other and the unspoken incident, along with future plans to once again bed their potions master, would be passed between the two. It was a fulfilled fantasy which would fuel their impassioned couplings for a very long time.

|o|

Severus watched them leave, slightly relieved and scared out of his mind. What if they repeated what happened in his rooms today? But more importantly, what if they never came back for a second go. He agonized every time he saw them and wondered at the end of every class if they would stay behind and proposition him again.

Late at night, when he was alone in his bed, he would remember that day. His groin would stir and he would tweak a nipple. Taking in sharp breaths and imagining it was Fred’s fingers on his nipple while his hand reached around behind him and probed at his entrance. Oh gods, if only it were George’s fingers exploring him. Moaning loudly and thrashing about on his bed, he would fantasize the twins were there, even thought they never came back.

The day they left on their brooms in their seventh year, he sighed and shook his head. He passed Harry muttering under his breath.

“There goes the best damn lays I’ve ever had and will never have again.”

He was sure no one could have heard him say it, but he didn’t notice Potter staring after him with a curious look on his face. The boy smirked and followed his professor, hoping to maybe get a little something for his effort in potions class and the war to come.

The End….Or is it…?
