Chapter Text
‘Psst – Harry!’
He turned, halfway along the third-floor corridor, to see Fred and George peering out at him from behind a statue of a humpbacked, one-eyed witch.
‘What are you doing?’ said Harry curiously. ‘How come you’re not going to Hogsmeade?’
‘We’ve come to give you a bit of festive cheer before we go,’ said Fred, with a mysterious wink. ‘Come in here ...’ [Harry Potter and the prisoner of Azkaban – JK Rowling]
Having nothing better to do, Harry decided to follow the twins inside the empty classroom.
“What is it that you wanted to show me?” Harry asked curiously.
“Well, dear Harrykins…” Fred said
“…we discovered that your larger-than-a-baboon uncle…” George continued in their typical twin-speech.
“…and thinner-than-bamboo aunt…”
“…refused to sign your Hogsmeade slip.”
“So as the kind hearted,”
“…gorgeous Samaritans we are…”
“…we decided to show you the source of our success.”
Not knowing what to expect, Harry had a sceptical look on his face. It was true that the twins were notoriously famous for their pranks, but even they had to admit that they were more often than not caught in the act by their head of house, professor McGonagall or the bat of the dungeons, professor Snape.
“We see you are in doubt, Harrykins…”
“…but let us assure you…”
“…it may seem like we spend most of our time in detention…”
“…but they haven’t caught us for nearly have of the stuff we pulled…”
Not waiting any longer, Fred reached inside the pocket of his robes and pulled out a yellowish, old looking parchment. He placed it on top of the nearest desk and looked at it proudly.
“An old piece of paper? Why is this the key to your success? What can it do?” Harry asked doubtfully.
“Just an old piece of paper?”
“Blasphemy, Harrykins…”
“This isn’t just a simple piece of paper!”
“Just watch.”
George poked the parchment with his wand while clearly saying “I solemnly swear that I am up to no good.” With a wicked grin.
The first few seconds it didn’t seem like anything would happen, but after a while thin ink lines began to spread like a spider’s web from the point that George’s wand had touched. They joined each other, they criss-crossed, they fanned into every corner of the parchment; then words began to blossom across the top, great, curly green words, that proclaimed:
Messrs Moony, Wormtail, Padfoot and Prongs Purveyors of Aids to Magical Mischief-Makers are proud to present THE MARAUDER ’ S MAP [Harry Potter and the prisoner of Azkaban – JK Rowling]
Harry looked at the piece of paper more closely and his mouth fell open in bewilderment.
“Is this what I think it is?” Harry gasped.
“Well, that depends…”
“…are you thinking that this is a map of Hogwarts…”
“…that also portrays everyone and their exact location?”
“Then yes, that is exactly what you are looking at.” They said with a proud smirk on their faces.
“You, guys, that’s amazing! No wonder you can wander the corridors at night without being caught. I have an invisibility cloak and even with that I have had to run from Filch and Snape. This is genius!” Harry exclaimed.
“We already know all the secret passages and the passwords, so we are willing to give you the map for future mischief. If we need it for a prank, we will share it and let you know first.” Fred said.
“Merlin, that’s awesome, thank you so much. Snape will never be able to catch me again!” Harry said while laughing childishly. “But I can’t just accept this from you, this is way too much! There has to be something you want in exchange!” Harry said naively not knowing that the twins had already prepared for it.
“You are right, Harrykins.”
“There is something you can do for us, as you know…”
“…we like to invent our own potions, mostly for pranking …”
“…but we also make some for our own private purposes.”
“Normally George and I test them ourselves, but…”
“…this time it has to be taken by a third party.”
“The only thing you have to do, is take this potion.” They said in unison.
They gave Harry a pink potion that smelt like strawberries. Without asking what the potion would do, Harry swallowed the entire content. After all, it was only fair: Harry needed the map and they needed a test subject.
It didn’t take long before Harry started feeling strange. His body temperature started to rise and he felt a flush on his face. It felt like thousands of tiny butterflies were in his stomach and miniscule ants were crawling all over his skin. To his horror, he felt something wet between his buttocks, it was like a gooey liquid that was dripping from his ass.
The wet feeling made his dick harden in arousal and his hole felt strangely empty. Which was weird, because things weren’t supposed to get in there, only out of it.
“Mhm, Fred, George, what’s happening? Why am I feeling so hot?” Harry moaned.
“It’s just part of the potion, little one…”
“…just do what feels natural.”
Harry immediately started to peel of his too hot pants and sweater. He was too busy undressing to see the lust filled looks the twins were sending him. When Harry was completely naked, he still felt way too hot and he noticed that the twins were coming closer to him. Fred was on his front and George was behind him. Simultaneously Fred started to touch his chest and gently play with his nipples, while George started to kiss his neck.
Their touches burned him, but against all logic it was a pleasant burn. Soon after the touches started, Harry felt one of George’s fingers press inside his butt. It didn’t take long before Harry’s cock was leaking precum and he started to rut against Fred’s thigh.
“Look how desperate he is, George! The little minx is practically humping my leg!” Fred said gleefully.
“I see it, Fred, you should see how his greedy hole is swallowing up my finger. He is so wet.” George smirked.
“Should we tell him, George? I’m sure he would like to know what the potion does.” Fred smirked back
“Go ahead, Fred, I think he’ll like it.”
“Well, my sweet little minx, do you know anything about the mating habits of dogs?”
“Ugh,” Harry moaned when George hit his prostate for the first time. “No, I don’t know.”
“Well, a female dog or bitch as you like will go into heat when they are ready to breed. They will produce a clear liquid that will attract a male. Afterwards the male fucks the bitch until she catches a litter. Normally the bitch can be in heat for several days, but we made a potion that will change this. It works on both men and women for approximately 3 hours. The subject will become desperate for cock and will do anything to be filled.”
“Mhm, please… I need more, please!” Harry begged. George had added two more fingers in his arsehole, but it wasn’t enough. He needed more!
“You are so pretty like this, Harrykins. Humping Fred’s leg like it’s your sole purpose in life and fucking back on my fingers. Such a good bitch for us.”
“George’s finger isn’t enough anymore, now is it? Maybe you should ask for something more. If you beg him, he’ll probably give you what you want.”
“Pl..please, George, need it! … ugh, please, … George more… mhmmm…” Harry groaned.
“You’ll need to be more precise, my little slut! I’m afraid I don’t understand what you mean.” George asked sadistically while stretching Harry’s arse with three fingers.
“Gehh” Harry moaned “your cock, please… Merlin, I need it… Need your cock… in me… please, George‼!”
“Why don’t you sit down on your hands and knees, little one? If you want to be bred like a bitch in heat, you’ll have to present your delicious holes like a bitch.”
Immediately Harry dropped on all fours. He presented his butt to George and opened his mouth for Fred’s pleasure.
With one quick thrust, both brothers breached Harry’s virgin holes. They didn’t wait for Harry to adjust to their significant sizes, but immediately started to set a brutal pace. All Harry could do was moan and groan between them. George’s cock stretched him so wide, that it resulted in a mixed feeling of pleasure and pain. Fred’s cock on the other hand tasted divine. Harry really wanted to take his time and get familiar with every inch of the appendage, but Fred didn’t let him. They would have time for a slow blowjob on another time. For now Fred would fuck his face roughly not minding the bitch’s comfort at all.
In-out, in-out, in-out… Harry slowly lost track of time. All he knew and cared about were the cocks filling him. Somewhere along the line the twins had switched places, now Fred was fucking him doggy style and George was using his mouth. Both of them were growling in pleasure while rutting inside of their little brother’s best friend.
After three hours the potion started to lose its power and the threesome was exhausted. With one last thrust Fred and George pulled out of Harry and started to jerk off their cocks in unison. Both of them came to a final climax and shot their loads on Harry’s back, ass and face.
They tucked their cocks back in their pants and left Harry naked, covered in cum inside of the abandoned classroom with the Marauder’s Map beside him.
Hogsmeade could wait one more month, Harry decided. Exhausted, he went back up the stairs to Gryffindor tower. The moment he touched his bed, he fell in a peaceful slumber. And if Ron or Hermione noticed his slight limp when they returned from the wizarding village, neither mentioned it.
In the coming years Harry would often express his gratitude on his knees between the twins’ opened legs.
