Kyuhyun and Ryeowook corner Yesung in their dormitory, both giggling madly and flushed red, and plop themselves unceremoniously on Yesung's bed. Yesung frowns at them above the book (Quidditch Through The Ages) he's reading. He can tell, from the way they're both watching him intensely and elbowing each other, that they want to tell him something, and they're practically bursting with it, so he sighs and plays along, carefully marking his page and putting the book aside on the sidetable, next to his wand, before lacing his fngers behind his head and leaning against the headboard. "Well?" he snaps at the two younger men.
"We have something for you, hyung," Ryeowook sing-songs. His eyes are almost glowing as he looks at Yesung, and Yesung feels his guard go up. Nothing these two normally plan together is good. He looks towards Kyuhyun, who grins and brandishes a beakerful of thick, mudlike gloop that Yesung realises is Polyjuice Potion.
Yesung sits up immediately, running his fingers distractedly through his hair. He's so focused on the Polyjuice Potion that he fails to notice Ryeowook's eyes follow the path of his hands and then fix on his face, the glow in them diminishing to a dark intense look. "Kyuhyun, did you swipe this during Potions?"
Kyuhyun smirks. "From under Slughorn's nose too, he never even noticed."
Yesung groans. "What are the both of you up to now? I'm a Prefect, Kyuhyun, how do you expect me to condone this? You know students are banned from using Polyjuice Potion!"
"You'll be singing a different tune once you see what we're going to do with this," Kyuhyun says, and beside him Ryeowook darts his tongue out to wet his lips, still staring at Yesung.
Yesung looks from one to the other, getting more suspicious by the minute. "Just wait, I'm not allowing you to do whatever it is - "
Kyuhyun ignores him and reaches over to tug at a lock of Ryeowook's hair, eliciting an angry squeal from the smaller boy before coming away with a single fine strand which he drops into the beaker. It froths and foams and turns a bright silvery colour before he downs it, smirking at Yesung all the while. Even as Yesung watches, wide-eyed, as Kyuhyun's skin seems to contract and bubble and twist in upon itself until there he is as Ryeowook, smiling shyly in robes that are just slightly too large for him, he still has no idea what they're up to.
"Kyuhyun, what are you doing?" he says, more sternly than he actually feels.
Then Ryeowook - the real Ryeowook, Yesung knows by his just-nice robes - crawls up the bed towards him and grabs his hands, pinning them by his sides, and leans in to kiss him, and Yesung thinks to himself, OH.
__________________________________________________________________________
Yesung's made love to Ryeowook countless times, but never in his wildest fantasies has he imagined that he could have TWO Ryeowooks.
Or, well, not really two Ryeowooks. Oh, he knows one of them is Ryeowook, and one of them is actually Kyuhyun, but right now it's pretty hard to tell.
Especially when both Ryeowooks are kneeling before him and sliding soft wet tongues up and down his hardness, or when one of them takes just the sensitive tip into his mouth while the other one runs his tongue across his balls, the combined sensations of one sucking and one licking making him buck and gasp and curl his fingers roughly into their hair.
He'd never dreamed this would happen either, when he's on his hands and knees and one Ryeowook is fucking him roughly and quickly and it's painful-but-oh-so-good, and the other Ryeowook (he thinks it's Kyuhyun, from the way he's reacting to Yesung's ministrations, different to how Ryeowook himself would normally react) thrusting wetly in and out of his mouth.
"Kyuhyun-ah," Yesung manages to gasp as the Ryeowook before him pulls out of his mouth, but then he smiles down at him and says, "I'm Ryeowook, hyung," before tugging at Yesung's hair, and Yesung responds to the unspoken plea by fitting his mouth back over his cock.
Then the Ryeowook behind him slams again into him and he just screams out, "Kyuhyun, oh my god!", his hips pushing back automatically and he hears a high-pitched laugh from behind him. "I'm Ryeowook, hyung," the Ryeowook behind him says, pulling out agonisingly slowly and then again snapping into him hard and fast without warning, and the Ryeowook in front of him laughs an identical laugh and thrusts back into his mouth, both Ryeowooks moving torturously in and out of him at both ends and Yesung feels so full, so filled up, even as the pleasure is so overwhelming he's almost drowning in it, saliva and precome dripping messily down his chin.
He reaches up blindly and grips on to the thighs of the Ryeowook in front of him for balance, grinding backwards as hard as he can, his fingers sinking into the soft flesh and his nails leaving red marks across the flawless skin, and the Ryeowook above him moans and tangles his fingers deeper into his hair, driving himself deeper into Yesung's mouth.
Behind him, Yesung can hear the Ryeowook there bite out a curse as he begins moving faster, hips moving back and forth like an automaton, and Yesung's almost certain that yes, that must be Kyuhyun, because Ryeowook never swears - but then that's driven out of his mind as the other man stops abruptly, and Yesung can feel him at his entrance, tantalisingly close, but he remains motionless.
"Kyuhyun? Kyuhyun, stop teasing, please," Yesung groans out, pulling away from the Ryeowook he's sucking on to look over his shoulder, and the Ryeowook behind him smiles the most innocent, most magnae-like smile he's ever seen and says sweetly, "I told you, hyung, I'm Ryeowook" and then he thrusts back in, so rough and so hard, slamming right into his prostate and Yesung would have screamed, but the Ryeowook in front of him suddenly bends down and kisses him, swallowing the sounds he's making, his tongue lashing against Yesung's and lapping up the salty remnants of precome on his lips.
Then Ryeowook (the Ryeowook he can see) wriggles himself underneath Yesung, his small body fitting compactly into the space between the bed and Yesung's body on his elbows and knees, and the Ryeowook behind stops and pulls out to allow the Ryeowook in front to position himself. Yesung opens his mouth to protest at the sudden emptiness but before he can speak (or beg, or plead, or moan, he isn't sure which) the Ryeowook underneath him wraps slender legs around his waist and pulls him forward, one hand moving down to find Yesung's arousal and guide it into him, the other hand clamped around Yesung's neck and kissing him fiercely, and Yesung jerks involuntarily as he finds himself buried to the hilt inside Ryeowook.
Ryeowook lets slip a small whine as Yesung brushes that spot inside of him, before he reaches out and grabs one of Yesung's hands and wraps it around his hardness, keeping his own delicate hand over Yesung's as he strokes up and down. He only dimly hears the Ryeowook behind him let out a long, low breath at the sight before he slams himself back into Yesung again, and this time Yesung really does scream into Ryeowook's mouth and Ryeowook gasps back, and the other Ryeowook groans as well in an identical voice.
Yesung's surrounded on all sides and in all dimensions by the little cries and sounds of both Ryeowooks, identical limbs tangled around him, one moving into him as he moves out of the other and sliding out smoothly when he moves back in and Yesung can't think anymore, his mind can't handle two Ryeowooks fucking him at the same time, rough velvet pulsating around him in front and rigid warmth ripping into him from behind and Yesung knows he's going to -
And then Yesung climaxes, long and hard, shouting Ryeowook's name into the soft sweet mouth under him as his entire body shudders and shakes, and it sets off a chain reaction as the Ryeowook behind him swears again and he can feel hot fluid staining his insides even as the Ryeowook in front of him drags nails sharply down his arms and pants his name as he comes as well over both their hands, still linked over his hardness.
They collapse, exhausted, still tangled together, until Yesung has the presence of mind to lift himself off the bed. He looks down, and sees Kyuhyun smiling up at him, back to normal now but glistening with perspiration. He gapes for a moment before flipping over, to see Ryeowook above him, smiling as well, his hair damp and sticking to his cheekbones.
"That was the most amazing thing ever, hyung," Ryeowook says, his cheeks tinted pink with the afterglow of his orgasm.
"We need to do this more often," Kyuhyun agrees, curling his arms around Yesung and pulling him back down beside him, before motioning to Ryeowook, who scoots over and presses himself contentedly against Yesung's chest, almost purring.
Yesung can only lie there, sandwiched between both of them again, as he tries to wrap his mind around the fact that both these boys - younger than him! - has just had a threesome with him - him, a Prefect! - while on Polyjuice Potion - stolen from a teacher! - and that Ryeowook has just topped him - the humiliation! - and sworn several times while doing it.
Long after the both of them have fallen asleep, Kyuhyun's leg flung carelessly over him and Ryeowook warm and flush against his chest, Yesung's still trying to figure out how he let this happen.
