Chapter Text
Harry laid on his back staring at the ceiling, he couldn’t possibly sleep while he’s still so furious. He turns his head to look at Ron’s snoring form. He can’t believe Ron thinks he’ll forgive him for ignoring him, he should never have forgiven him for abandoning him during the tournament...he isn’t going to make the same mistake twice. He should have told him what was happening no matter what Dumbledore said. He needs to show Ron his place. He gets up and tosses on his cloak, wanders quietly through the halls peering into different rooms. He finally finds what he’s looking for. The infamous Black family library. He grins widely as he begins searching for a book likely to contain the spells he’ll need.
It takes most of the night, but eventually he’s found spells that will do everything he’d hoped, and more. He can’t wait to start. Unfortunately he’ll have to...unless. He grins to himself. He could use one or two really quickly, Ron sleeps like the dead and no one else will be up for a bit. He puts the current book back on the shelf. Then looks around thoughtfully. He can’t let Mrs. Weasley find this place or she’ll purge it of everything that makes it special. He fetches a book he’d set aside earlier and uses it to cast a spell hiding the room from everyone but himself. There. Now he doesn’t have to worry about losing the chance to learn more delightful curses.
He heads back to the room where his victim is waiting. He casts the first spell and Ron mumbles quietly in his sleep. He smirks and casts another. Ron sleeps on unaware as he casts a third and then a fourth. Perfect. He’ll save the rest for tonight. He’s going to need to nap this afternoon. He lays down to get an hour of sleep before breakfast.
~~~~~~
During breakfast he watches Ron out of the corner of his eye. Ron keeps shifting in his seat. He looks uncomfortable. He smirks internally. It must be driving Ron mad not knowing why he’s feeling the way he is. He can’t wait for the other spells to progress to a noticeable degree. He watches Ron attempting to hide his erection as he leaves the table, he almost laughs when he sees Ginny get an eyeful of it. Ron sees her wide eyes and makes a hasty exit. He finishes his tea and follows a moment later.
He finds the room empty. Apparently Ron retreated to the bathroom to deal with his problem. Unfortunately for him he won’t be able to. Harry sits on his bed with his notes from the night before and waits while planning that night’s events.
It takes almost an hour before Ron gives up and slinks into the room looking a bit green. Harry has a hard time pretending concern while trying not to laugh.
“You alright, Ron?”
“F-fine.”
He watches Ron collect a book from his trunk and sit pretending to read. Hermione comes looking for them so they can help clean more and Ron has to beg off with the excuse of his not feeling well. Harry goes to help clean, annoyed that he won’t be able to watch the rest of Ron’s punishment play out. But when Mrs. Weasley hears something’s wrong with Ron she insists on going to check on him. Harry stands outside their room with Hermione, Ginny, and the twins. Using extendable ears to listen in as Ron haltingly explains the problem. Mrs. Weasley is very concerned and begins casting diagnostics and attempts to fix the problem with a spell. The diagnostics come up clean and the spell fails. She gets extremely concerned at that point, convinced he must have come into contact with a cursed object. She decides they’ll have to wait until Snape comes by for the meeting later and have him fix it. He’s their best expert on dark curses after all.
She leaves and they all crowd into the room to keep Ron company. Which lasts for about twenty minutes. Ron insisting he just wants to be alone right now. The others leave, but Harry stays. He has a feeling Snape will know a counter for the spell he used. He has to try and prevent that.
He sits beside Ron, who ignores him. Too embarrassed to speak to him no doubt.
“There’s one thing you haven’t tried.”
Ron looks up, looking hopeful. He waves his wand, locking the door and putting up a silencing charm. Then reaches for Ron’s trousers. Ron cries out and jerks away.
“Just let me try, Ron. It might be that you need someone else to relieve it.”
He ignores Ron’s protests and pulls out his weeping erection. He makes sure to exclaim over the size.
“Very impressive. I don’t know why you were determined to hide such a large cock, Ron.”
He stares at Ron’s face while he wanks him. He had rather hoped Mrs. Weasley would do this, but seeing how uncomfortable Ron is, he thinks he might like this better anyway. It would’ve been fun knowing his mother was having to wank him all the time, but he likes this too. He can’t wait till he realizes he’ll need his help climaxing from now on. He begins whispering to him as he wanks him.
“This is what you needed isn’t it? You just needed someone to touch you. You’re a needy little thing. A slut.”
Ron shakes his head in a denial. He rubs his thumb over his cockhead and watches, biting his lip, as it pushes Ron over the edge. Ron climaxes, screaming, and covering himself in cum. Harry continues milking his cock as Ron cries from the overstimulation. He pulls out rope after rope after rope of cum, until only drops are coming out. He watches eagerly as Ron’s bollocks once empty shrivel away and disappear. Ron lays there panting for long minutes. When he finally rouses he notices his lack of balls and immediately begins crying. Harry gentles him with soothing touches.
“It’s alright, Ron. You’re going to be fine. You never used them anyway. Or did you think someone was suddenly going to want you?”
Ron looks up at him, astonished. He gives him a vicious smile.
“We both know no one will ever want you, Ron. You’re lucky I’m even willing to touch you. Although my help doesn’t come free. Strip.”
Ron shakes his head, glaring at him. He points his wand at him. Ron tries to dive away but he hits him with a stupefy. He strips him with a spell, ties his limbs to the bedposts with another, and begins stripping himself. He collects his notes and wakes Ron. Ron begins thrashing in his bonds as he begins casting spell after spell on him. Once done he lines up his hard cock and forces it inside. As soon as the head is in Ron screams, he smiles, and forces his cock deeper. Once fully seated he stills for a moment.
“Just so you’re aware I cast a few delightful curses on you. You’ll never be able to climax again without my help. You’ll always have constant erections. You’ll never impregnate anyone now that your balls have been removed. And best of all, you’ll never be able to tell anyone who did this to you.”
He smirks at Ron’s glare. God, he’s so glad he decided to do this. He hopes Snape can’t counter the more enjoyable curses but at least he knows the man won’t be able to regrow his balls. He rubs the skin where they used to be. Perfect. He begins thrusting, changing his angle a few times till he nails Ron’s prostate. He watches Ron struggling not to show the pleasure he’s feeling as he rams into his prostate again and again. He begins thrusting faster, pounding into Ron hard enough to bruise, Ron whimpering at each impact. He pinches one of Ron’s nipples, then begins pulling on it as he fucks him into the mattress. It doesn’t take long for Ron to climax once again, his cock visibly shrinking after. He laughs when Ron releases an anguished howl at that.
“Oh shush, it’s not like you were ever going to use it again anyway, and besides that curse I cast on you earlier is still in effect. You should be happy it’s shrinking. Eventually it’ll be so small no one will notice you’re hard all the time.”
He pulls out as Ron begins sobbing, holds his mouth open, and fills it with his cum. There’s a soft glow surrounding Ron for a moment. Ron’s eyes go wide and he smirks down at the pathetic mess his former friend has become.
“Would you like to know what that spell does?”
Ron glares in response, it’s not very impressive considering he’s still sobbing.
“Well, then you’ll find out later.”
He cleans them both with a spell. Orders Ron to get dressed and hold his tongue about all of this. Ron glares but is forced to obey. Then he dresses himself and sits watching Ron squirm.
~~~~~~
Snape arrives for the meeting that evening. Mrs. Weasley comes with him to check on Ron and Harry pretends to be napping so he won’t be shooed out. He waits with baited breath for Snape to finish his examination. He hopes the man can’t undo his hard work. Snape casts a few diagnostic spells and inhales a sharp breath. He snaps out an order for Ron to strip and Ron, very reluctantly, obeys. He listens to the rustle of Ron’s clothing, smiling into his pillow. Mrs. Weasley is shocked and horrified by the state of her son’s genitals, she pleads with Snape to tell her he can be healed.
“I am afraid the damage is permanent, and it will only worsen over time. I’m not sure how small his penis will eventually get, but he won’t be using it to penetrate anyone ever again. May I speak with him alone, Molly?”
Mrs. Weasley leaves to go inform her husband. As soon as the door is closed...
“You can cease pretending to sleep, Mr. Potter. Explain to me why you have done this.”
He sighs. He should’ve known the man would figure it out. He rolls over, sits up, and shrugs.
“He’s been a shitty friend. I wanted to make him suffer.”
The man stalks closer and he tilts his chin up. He won’t cower.
“And do you still want that? To make him suffer?”
“Yes.”
“Mm. Then perhaps you won’t mind sharing him. You aren’t the only one he has been an annoyance to.”
He grins broadly, he had never hoped for an outcome this good.
“Gladly, sir. I would love for you to use him. You can even share him with your friends.”
“If I do that he might end up scarred.”
He smiles viciously and Snape smiles back. They turn toward Ron, who is once again crying. Harry laughs at the sight of his rock hard cock. It’s still fairly big but it won’t be for much longer. Harry orders him to his knees, while Snape pulls out his cock, then forces it inside Ron’s mouth. Harry watches gleefully as Snape shoves his cock down Ron’s throat. He nudges Ron up onto his hands and knees and thrusts his cock into his arse. It glides in easily with the slick he cursed Ron to make. He begins fucking him harshly, making sure to nail his prostate on every thrust. They fuck into him quickly, they can’t be sure how long they have before someone comes knocking. Snape climaxes first and Harry follows soon after. Ron didn’t cum on his cock so he sits on the side of the bed and drags Ron into his lap. He strokes his cock slowly, while telling Ron how worthless he is. Ron cries the entire time. He soon grows bored and so he digs his fingers into Ron’s arse and collects some of his cum. He makes Ron lick his fingers clean while continuing to stroke his cock. Ron climaxes helplessly at the first taste. He watches in delight as his cock shrinks further. He strokes him back to hardness, can’t have anyone seeing him soft and realizing what type of curse he’s under, then Snape cleans them with a spell and he orders Ron to dress.
~~~~~~
The next morning he wakes to the sound of Ron whimpering in his sleep. He smiles. It’s starting already. He gets up and walks over to Ron’s bed, kneels next to his head, and pulls out his cock. He pulls Ron’s face up to his cock while stroking himself to full hardness. Ron opens his mouth automatically, while still sleeping, and he slips the head inside. Ron begins suckling on his cock and he groans.
“That’s it. Good slut. Just like that.”
Ron wakes with a start, looking horrified. He gives him a stern look.
“Keep sucking or I won’t let you have my cum today. With the curse I used you’ll be begging me for it by the end of the day. In front of everyone.”
It takes a moment but he does resume sucking. He thrusts gently into his mouth. He’ll have to wait till tomorrow to shove his cock down his throat. Right now Ron needs to taste his pre to reinforce his spellwork. He orders Ron to strip and then begins stroking his already hard cock. He wants to fill his mouth with cum while Ron’s cock shrinks yet again. It doesn’t take long for Ron to begin thrusting up into his hand, unable to help himself. He feels himself getting close and squeezes Ron’s cock almost to the point of hurting him. Ron climaxes with a cry, muffled by the cock filling his mouth. He watches his cock shrink while climaxing. Ron drinks his cum down eagerly, looking half aroused, half horrified. Then licks his cock clean. He pulls away after a long moment, having to hold Ron back as he chases his cock with his mouth, and makes sure to point out his new size. Ron begins crying quietly once again.
“Stroke yourself back to hardness while fantasizing about Snape fucking you.”
Ron sobs but does as ordered. Not that he ever had a choice. He’s soon hard again and Harry lets him stop for now. Perhaps later he’ll have him stroke himself raw, chasing an orgasm he’ll never reach.
~~~~~~
Ron lasts until just after dinner before he begins staring at him, he smirks at the slut before making an excuse for them and accompanying him upstairs. He sits on the edge of the bed.
“Figured out what that curse does yet?”
“Harry, please, please, don’t do this.”
“You want me to stop providing you with orgasms, even though it means you’ll never have one again? Or do you want me to deny you my cum even though it’ll leave you so desperate for it you’ll do anything to get another taste?”
Ron glares. He smirks again, and pulls out his cock. Ron’s eyes snap to it and he instantly moves to kneel at his feet. He pets his hair mockingly.
“Good boy.”
Ron’s too busy licking his cock to notice, much less mind, his mocking. He grabs a fistful of Ron’s hair and forces his head down onto his cock until it’s snugly ensconced in his throat. He holds him there while he chokes for a long moment, picturing him choking to death on his cock. Hm...maybe later. He pulls his head off, lets him take a single breath, then begins fucking his throat. Ron moans happily around his cock. He decides the arsehole needs to learn what life will be like for him if he ever pisses him off again. He isn’t going to let him cum until after they’re back at Hogwarts. Besides this way he’ll have to keep hiding his noticeable erection for the rest of the summer. By the time he helps him out again Ron might be so grateful he won’t even mind his cock shrinking. That would be amusing.
He continues fucking Ron’s face for several more minutes before climaxing, Ron drinking down his cum eagerly. He pushes him away after he’s done his best to lick his cock clean.
“Good slut, but that’s enough for now. Right now I want you to rim me.”
He makes sure not to make it an order. He watches Ron as he slowly snaps out of his cum induced haze. He smirks at the horrified look on his face.
“Keep in mind if you don’t keep me happy I’ll cut off your supply of cum. If that happens you’ll soon find yourself attempting to suck me in front of whoever happens to be there at the time. Do you really want your family to see you like that?”
Ron glares, he’s so angry he’s shaking. He smiles broadly and strips himself with a spell. He lays back and spreads his legs.
“Well, go on.”
He watches as Ron leans forward and hesitantly begins licking his arse. He has no curse induced desire clouding his judgement for this. He’s fully aware of what he’s doing. He laughs when he sees Ron’s crying. He strokes his hair mockingly.
“You’re terrible at this Ron. You’re going to need lots of practice. Don’t worry, I’ll make sure you get it. Although we won’t have time to sneak off every evening so we’ll just have to make do. You’ll be blowing me every day in the dorm anyway, you might as well rim me in front of our dorm mates as well. I’m sure they won’t mind. We’ll explain you were cursed into a needy little slut.”
Ron stops and stares at him, utterly horrified.
“That curse I used can be keyed to other’s cum as well. I have no doubt they would all love to help keep you satisfied. Would you like that?”
“Please, please...”
He shoves his face back down, cutting off his mindless pleas.
“I might change my mind if you put in proper effort now.”
Ron begins trying to please him, but he still has no clue what he’s doing. He begins instructing him as best he can. He finally climaxes again and kindly lets Ron lick up his cum.
~~~~~~
That night he gets into bed with Ron. Ron makes a noise of protest but doesn’t dare say anything. He strips them both with a spell and sinks into Ron’s wet arse. He doesn’t fuck him though. Just drifts off to sleep with his cock snug and warm.
In the morning he’s tempted to fuck him but since that might give him an orgasm he has him suck him instead.
After breakfast he goes in search of a solution. It takes longer than he’d like, he’s glad Mrs. Weasley decided it wasn’t safe for them to continue cleaning, but he eventually finds a spell to temporarily numb a part of your body. He grins wickedly and then goes in search of his plaything.
He finds him holed up in their room. Convenient. He locks the door, strips them both with a spell, then has him present his arse. He sinks inside and thrusts into him a few times, making him groan and push back eagerly. He smirks and casts the spell. It takes a moment for Ron to feel the difference.
“Why did it stop feeling good?”
“You aren’t allowed to cum without my permission Ron. Your next orgasm will be on the second of September. After classes are over for the day. By then you should be properly grateful for my gifting you one, don’t you think?”
He snaps his jaw shut with one hand to cut off his whining, and pinches his cockhead with the other.
“You will stop complaining if you know what’s good for you.”
He lets go and Ron dutifully stays silent. He fucks him good and hard while telling him how pathetic he is. Ron behaves so well, clenching his arse around him and pushing back against him that he pulls out and lets him drink his cum.
“Good boy. Finally learning your place.”
He cleans them both up then opens the door and stares at Fred and George. Who are holding extendable ears and look half-horrified, half-intrigued. He sighs and motions them in. Damn it. He can’t believe he forgot the impervius charm.
He folds his arms and waits.
“So you turned our little brother into an even littler brother.”
“And apparently also a slut if those sounds were anything to go by, Gred.”
“True enough, Forge, true enough.”
He grins at them both and strips Ron once again. They grin back and use the same spell on one another. He sits on his own bed after casting a locking, silencing, and impervius charm on the door. He watches, smirking, as they maneuver Ron into position and both slide inside him. One in his arse, the other his mouth. Ron refuses to suck at first but he clears his throat and Ron begins sucking at once. He gets two pairs of raised eyebrows at that.
“You’ve trained him well.”
“And so quickly too.”
“You must tell us your secret. We have our eye on one Percy Weasley. He needs to be put in his place.”
“Needs to learn to respect his family.”
“He’s already a bit of a slut though, can’t tell you how many times we’ve caught him on his knees.”
“Think that’s how he got the ministry job actually.”
He begins explaining as they fuck Ron from both ends. When he’s done they congratulate him on his cleverness. Apparently they’d been wanting to do something similar but two of the spells they needed were incompatible. He just happened to find alternate ones that aren’t.
They finish fucking Ron and leave him lying in a puddle of cum. A literal puddle. They see the look on his face and teach him that particular spell at once.
