Work Text:
Remus is lying on his bed reading a book, seemingly completely relaxed and completely unaware that his best friend is having an existential crisis in the bathroom they share.
James and Regulus have been dating for a few months now but have never gone beyond the stages of kissing and a few wandering hands here and there. Now, Reg invited him to a “date” at his dorm next week, and assured him that his friends will be busy elsewhere. James is not a prude; he knows what that means. He's as excited as he is terrified. He never got to that point, not even with Lily; and this is his very first experience with a man and he is scared to death of doing something wrong and not being good enough for Regulus.
That's why James is pacing around the bathroom trying to get up the courage to ask Remus for advice on the matter. Talking to Sirius about this is completely out of the question; you can't ask for advice on how to have sex with someone's little brother. And Pete is too straight to have the answer he needs. But Remus…oh Remus is the most experienced and knowledgeable person he knows.
So, still with shaky legs and the look of a terrified animal in his eyes, he opened the bathroom door and in three steps he was in front of his friend's bed, holding on the open curtains to keep himself upright.
“God, Prongs. What happened to you? Did a werewolf bite y-” the smile that was forming on his face quickly crumbled when James practically screamed in his face.
“MOONY, COULD YOU TEACH ME HOW TO FUCK A MAN? ” Moony's look of utter shock lasted for an agonizing moment before he burst out laughing. He wiped away a tear and closed his book, putting aside before answering.
“Didn't mommy and daddy Potter teach you how things are done?”
“Stop laughing, Moony! This is a very serious matter! I know how the basics are done, but I want to know how to make it good and pleasurable for the other person…” James threw himself onto the bed, utterly defeated, his hands running through his messy curls.
He could feel Remus's body moving slowly across the bed and sitting close to his head. The heat from his body heated James's flushed cheeks even more. James looked deep into his friend's wide shining eyes and begged.
“Moony, please. I want to be good for Reg. I don’t want to hurt him. I know it's my first time, but I hate going into the field unprepared. Please.”
As James spoke, the golden eyes that looked down at him darkened, and he couldn't read the expression on his friend's face. He felt heat all over his body and was afraid he crossed Remus's personal boundaries. So he tried to get up quickly from the bed.
Remus's heavy hands pulled him back onto the bed as James began to mumble weakly “ I'm- I'm sorry! I didn't-”
“Prongs, it's okay! I'll be happy to help you with whatever you need. But you'll need to explain how far you've come, so I know what we're working on.” James felt his heart relax and he melted into Remus's touch, who is so reserved about touching other people. James, who is sitting on the bed again, sat a little closer to his friends and responded quietly.
“We didn’t get very far to be honest. We kissed and did some hand work but we always got interrupted before we could do anything else. But next week we'll have his dorm perfectly free for a couple hours. Do you understand now why I need your help?”
“Ok… have you ever received a blowjob from someone?” Remus asked and moved his hand from his friend's shoulder to his thigh.
“Yes…yes Lily-”
“Great! So you already know what you like; just replicate in Reg what you already know is good.” He spoke cheerfully as he was talking about any other subject in the world.
“This will be your first lesson!” James could feel his eyes widen and his mouth open.“Dear Prongs, you already know that before jumping into action, you'll need to have some foreplay with our dear Reg, right?”
“Yes… but-”
“Amazing! Use foreplay to relax both of you and build the tension. For the second lesson , it's easy. Use a lubricating spell and don’t forget to finger him wide open. Then when you enter go slowly and let him set the pace. Later, don't forget the aftercare. That's basically it. You'll do great, Prongs! Pride of Gryffindor!”
James felt his heart race again. Everything seemed so simple and natural when Monny spoke. Why did it seem so difficult for him? James felt his hands begin to sweat and tremble a little. He looked down, away from his friends' questioning gaze, and tried to control his breathing.
Moony held his trembling hands with one hand and with the other one gently lifted his face, caressing his jaw with his thumb. In a soft voice he spoke.
“Calm down Prongs, no one is demanding perfection in something you've never done before. You have the right to learn calmly.”
“But how do I- how do I hold it? With both hands or just one? What if it doesn't- it doesn't fit in my mouth? Does it have to reach down my throat? If I choke, will it hurt him? What if it touches my teeth? How will I know it's- is open enough? What if he pretends it's fine, but I mess it up and it's horrible and he hates me?” The words were running out of his mouth way too fast.
James feels very frustrated, it's much easier to get to his broom and exercise until his body can't take it anymore.It's easy to play and win a quidditch game, it's easy to pass the year's subjects. But this time he doesn't feel confident. Not when it comes to being enough for someone like Regulus. He's not used to feeling helpless. In an act of exhaustion, James rests his head on Remus's tall shoulders.
After a few moments of silence filled only by the breathing of both of them, Remus spoke again.
“I think I know a way to teach you in a more practical way, one way that will give you more confidence, but…” James felt a voice tickle his ear and looked up.
“Anything, Moony! I'll do anything!”
“Good.” Remus's voice was husky and his eyes were steady as he reached for James's hand and very slowly placed it on his groin.
“Moony-” James's eyes were wide but he didn't move his hand.
“It's just going to be some type of a practical class. I will be your professor.. It won't influence or change anything in our friendship.” He spoke with great clarity and confidence. James agreed and nodded, still a little shocked but committed to the idea.
“Sirius and Pete are in double detention with McGonagall.”Remus sat up straight and straightened his posture. “Get on your knees, Prongs.”
In the blink of an eye, James was on his knees between Remus's legs, looking up waiting for the next instructions.
“ When you're with Reg, you'll want to make him feel like the center of all your attention. You'll undress him slowly, looking him in the eye.” James, who understood this as an order, moved his uncertain and trembling hands towards Moony to unbutton and lowered his zipper, with one jerk, the pants came off entirely. Then he unbuttoned his blouse but didn't remove it completely.
Moony looks handsome like this. Confident eyes, head hanging to the side white blouse on his shoulders and a half-hard cock resting on his thigh.
“You can hold it with one hand. Start licking from the base to the tip, slowly until it hardens fully.” Monny’s texture was surprisingly pleasant, James licked it happily. “ Run your tongue over the tip and suck. When you think you're ready,put it in your mouth as far as you can.”
Moony's cock was growing bigger and bigger, it certainly wouldn't fit all the way in James' mouth. But that was okay, he thought, Reg was smaller, he'd make it fit.
He went down as far as he could and felt a small moan escape the other's mouth. This gave him the confidence to continue sucking with enthusiasm.
“Monny, I didn't think you would taste so good.” James spoke, lifting his face and catching the other eye with a smile. Remus moaned loudly this time and wrapped his fingers in James's curls and pushed him down. He held his head until the tip of is cock reached James's throat. His eyes rolled back in pleasure as he felt his friend choke.
Remus fucked Prongs throat until tears and spit were running down James's mouth
“That's enough James. Stand up and take off your clothes” Remus gave these orders as he climbed further into the bed and lay down on the pillow.
“How does the professor think I did in my first lesson?” James asked with a beaming smile and a husky voice as he stripped off his clothes and climbed into the bed to find Moony.
“Your mouth was delicious.”
“What are you going to teach me now, sir?” James's hand ran down Remus' neck, resting on his thigh, feeling his own hard cock leaking into the body next to his
“I usually don't like being the bottom, but this time I'll make an exception for the sake of your studies” The voice came out from the middle of a sarcastic smile.
“Thank you, sir. I feel flattered.”The answer came in the same playful and sarcastic tone. Remus took his wand from under his pillow and pointed it at himself, performed a lubrication charm, and quickly the wand disappeared again
“Start with just one finger, going in and out”
James positioned himself again between his friend's legs, placing them on his shoulders. He stared at that little pink hole, blinking in anticipation. It's beautiful. He planted a kiss that wasn't enough to quench his curiosity. James hungrily licked Moony's hole, again and again and again until he heard the boy sigh and moan softly.
He inserted half his finger at once. When Moonys moaned in surprise, he inserted the rest and began to move.
"Moony, I was serious when I said you tasted really good."
“Mmmh…Prongs, more- put one more finger in... scissor me... yes, just like that... Ugh” James was scissoring him hard and fast now.
"Oh Moony, you're still so tight in here, I don't think I'll be able to get in," James said almost tearfully as he rubbed his aching erection against the mattress.
"Put another one in... Mmmh... Prongs, you're doing great, don't stop..." James took his other hand off his own erection to hold Moony's hips, which didn't stop moving. He used force to keep him in place.
Moony reached for James's hand between his legs and pulled his fingers out of himself. He was breathless, his cheeks and chest flushed.
"Put your cock inside me," Remus commanded, his voice firm and his eyes hungry.
"Oh Merlin—" James felt like he was in another world.
When James reached his erection, it was big and fat. The head was red, and he made a puddle of precum on the mattress. He positioned the head of his cock at Moony's hole and admired the sight for a second, wondering once again how he would fit inside his friend.
Remus wiggled his ass against James's cock, daring him to enter all at once. Their eyes locked. James thrust in, and a tear of pleasure fell from Remus's eyes. James couldn't hold back, and as he licked Monny's cheek, he thrust again.
"You're so tight, Moony... Merlin... Uggghhh." With one more thrust, he was completely buried inside Monny.
Remus's moan was loud, and he clung to James's neck. Remus gasped for air as Prongs moved inside him.
"Good boy, Prongs, you're filling me up."
"Moony-Moon...Mmmmm." James snuggled his head against Remus's shoulder, breathing in his sweat and trying to suppress the monstrous urge to cum when Moony called him a good boy.
"Can I—can I move faster? Please?"
"Prongs, a good student like you can do whatever you want with me." James felt himself glow with each compliment Moony gave him; he felt like the sun.
He pulled his cock out of Remus and easily flipped his long body over, placing him on all fours in front of him.
"Is this how wolves like you like to be fucked?" With one thrust, he was inside Moony again.
"Ooh fuck! Prongs fuck fuck..."
James spread Moony's ass cheeks and admired how his cock stretched his friend's once-small hole. He moaned loudly with otherworldly pleasure. James gripped Remus's sandy hair with one hand and held his waist with the other to move faster.
"Professor—aah—may I? Please? Mmmmh—may I?" James's vision was starting to blur.
"Use your words, Potter!" James could feel Remus tightening and his moans growing louder and more uncontrolled.
"Can I cum inside you, sir? Please?" James's hands were already on Moony's neck, turning his face so they could look at each other.
"Yes! Fuck—yes! Cum inside me, Prongs, fuck, fuck!"
Moony felt James's hot cum filling him. He came uncontrollably at the sensation of being filled by his best friend.
"Aah, motherfucker- mmmmmmnh." Remus's orgasm lasted forever, with James still pounding inside him.
They both fell exhausted onto the sheets, stained with cum and sweat. As they lay there, James's cock slipped out of Remus, and his cum cascaded out of his ass.
"James, go get a towel to clean me up." Remus's voice was weak. James stood up limply and ran to get a wet towel and clean his friend carefully.
"Congratulations, Prongs, you're ready to fuck your boyfriend." They both laughed together.
