Fred and George walked slowly towards the Dungeons. It was Friday night, and they had detention, again. While most detentions they usually deserved, this one was a bit unfair.



Serena Stillwater was a prat as far as they were concerned. A sixth year, stuck-up Ravenclaw, they tried to ignore, but today she had brought it on herself.



She had pranced into the Potions room and shot the twins a look before sitting down in front of them. Her back was ramrod straight; every blonde hair on her head smoothed into some fancy little twist in the back, and the ends of her glasses resting snugly behind her ears.



Professor Snape was in a snit and barked at the class to brew the potion written on the board. He stalked around the room sneering at his students and making rude comments about their progress. Fred had stood up to go get ingredients from the storage closet and Serena chose that exact moment to stand up and turned right into him. A burning sensation had traveled down the front of his robes and they both yelped.



“You stupid idiot! Look what you’ve done.” Serena’s hazel eyes flashed as she poked her finger into Fred’s chest, which was covered with the contents of a beaker she had been holding. “Now I am going to have to start over.”



“Me? You’re the one who jumped out of your chair and slammed into me!” Fred crossed his arms over his chest and glared at her.



Serena turned around and grabbed a vial off Fred and George’s desk. “You lot can turn in an unfinished potion, I’m taking this.”



“I don’t think so, luv.” George grabbed at her arm and spun her around; the vial went flying and crashed on the floor. The contents splashed the ends of a long black cloak, which was unfortunately worn by Professor Snape.



“Detention. Tonight at nine o’clock sharp.” He waved his wand and the contents of both desk disappeared. “And you three will get zeros for today’s assignment.



Serena had glared at the two boys and they returned the heated gaze.



The twins entered Professor Snape’s office and stopped when they saw that Serena was already there. “You’re late, that will add an additional hour to your detention. Now follow me.” Snape pushed past the boys and started towards the end of the hall. The ground below them began to slant downwards towards a door at the end. Without pausing the door swung open and the four of them continued deeper into the bowels of the dungeon. The walkway became narrower and the temperature dropped but they continued on. After a ten-minute walk they stopped in a hallway with several wooden doors.



Snape pushed one open and waved his wand, several torches lit the cavernous room. They all stepped in and the overwhelming smell of damp earth assaulted them. The walls were lined with shelves and four more rows down the center.



“This is a storage facility for needed, yet seldom used potions and such. It needs to be cleaned out of everything that is over one hundred years old. “ He waved his wand and an overly large cauldron appeared near the door. He handed Serena a clipboard filled with parchment and a quill. “Throw out the old stuff and make note of it. Break anything unnecessarily and I will add another detention.”



He turned to leave but paused in the doorway and turned, he waved his hand and the students’ wands shot towards it. “You have three hours, work quickly I want it all done tonight.” He disappeared through the door and it slammed shut behind him.



“Well, this will be loads of fun.” George stormed off towards a shelf, grabbed a jar and chucked it at the cauldron.



“Did you even bother to check the date?” Serena retrieved the jar and set it back on the shelf. “Look, you two do that side of the room and I’ll do this one. I’m sure I will get more done than the two of you together.”



Fred rolled his eyes at her and stalked off towards his brother, the two began taking turns chucking jars.



An hour later the twins were sitting with their backs against the first row of shelves. They were watching a bewitched quill scribble across the pages of parchment, which were floating in the air.



“She may be a prat but she managed to do a wandless spell….’



“… to make life easier.” George finished Fred’s sentence as the quill scribbled yet another word she called out.



There was a muffled oath and a minor crash that seemed to echo around the cave. The boys looked at each other and shrugged but then jumped up when the clipboard and quill crashed to the floor.



“That can’t be good.” Fred walked slowly towards the papers and bent to pick them up.



George wondered over next to him and stared down too, “should we check on her?”



Fred looked towards her half of the room and shrugged, “Why not? Nothing else to do.”



The boys looked down the first row and only saw rows of neatly lined bottles and jars, labels out. Her discarded school robe hung from the corner of a shelf. They meandered towards the next row and froze for a split second then bolted towards the end.



Serena was suspended nearly four feet off the floor, her feet kicking wildly at the wall while her hands fought for purchase on the vines entwined around her neck. A thick band of vines encircled her chest, waist and upper right thigh. Her face was turning a horrid purple shade and her eyes were begging for help.



Fred flung his hands around her waist and hefted her up as high as he could to try and ease the pressure choking her. As soon as he touched her, a vine snaked its way around his torso.” George! Do something. Serena, stop fighting!”



George raced back up the isle and wrestled a torch from its holder on the wall, when he slid to a halt behind Fred; he shoved the torch against the plants tentacle like vines and it shriveled back up against the wall. Serena’s weight dropped against Fred and he stumbled back, slammed against George and the three of them fell in a heap on the floor.



George scrambled out from underneath Fred’s head, his hands were waving back and forth, and he had no idea what to do. “Fred, are you okay?”



Fred nodded his head but the movement seemed painful. He slid one hand behind his head and rubbed the area that had struck the floor. Serena was sprawled across his chest gasping for air. George started gently rubbing her back chanting, “It’s okay, you’re going to be okay.”



The back of her shirt was shredded and blood was seeping from several abraded areas. A deep gash ran across her shoulder blade and blood was pooling around it. George ripped off the tattered remains of the back of her shirt, wadded them and pressed it against the deepest gash on her back. Her back arched down and she and Fred both gasped, but for different reasons.



George’s eye’s followed the path of the abrasions downward; her blue and gray plaid skirt was hiked up around her waist, revealing pink cotton knickers. He swallowed and managed to look past that to the cuts covering her backside and the thick bruises already forming on her thigh. One shoe was missing and he saw it lying on the floor near the wall, her wire-framed glasses lay near the shelf.



The horror of the moment and the adrenalin rush was mixing with the cold in the room and her body began to shiver and jerk uncontrollably. Fred wrapped his arms around her as sobs began to erupt from her.



It had been less than three minutes since they had seen her dangling from her neck, she was alive but hurt and George knew they needed to get her to the hospital wing. He jumped up and disappeared down the aisle, a moment later Fred heard him yelling from the other side of the room. “Bloody wanker locked the door!”



He returned holding three wall torches, her robe and a jar of yellow fluid. He shoved the torches into the shelf structure close to the floor and the warmth began to spread across Serena and Fred.



“What did you find?” Fred lifted his head off the floor to see what was in the jar. He was still holding Serena against his chest; her body trembled as little sobs continued to escape from her.



“Murtlap Essence. It was the first thing I chunked into the cauldron earlier”



“Great find mate.” He unwrapped his arms and tried to move out from underneath her but she burrowed against his chest. She tried to say something but ended up coughing instead. George began smearing the Murtlap across her back and she shivered a little before letting out a sigh against Fred’s neck.



Despite the fact that she was injured, and had nearly been killed by a stupid plant, Fred’s body could not help responding to the fact that she was lying across him like a blanket. Her breathing had evened out to a raspy wheeze and her warm breath was caressing his skin. He felt useless just lying there, but he wasn’t about to make her move. Every time she moved her leg brushed across his slowly hardening cock.



George moved slowly down Serena’s back and then to the back of her knee where the abraded area ended. He tried hard to keep from looking at her pink knickers but that was the direction his hand was moving. “How are you doing down there Fred?” He had to distract himself somehow.



Fred made a non-committal noise and pushed himself up on his elbows. Serena moved with him, her legs were straddling his lap and the muscles in her thighs gripped him when she tried to keep him in place, he moaned at the sensation.



She started to move off of him but he stopped her by putting a hand on her hip. “Not quite done, give him a minute okay?” She nodded her head and lay still.



George looked Fred directly in the eye before going back to his task. His hand moved cautiously to the inside of her leg and then he had to close his eyes as his fingertips skimmed the soft outer skin of her cunt. He felt the muscles in her thigh jerk in response and he quickly moved to her derrière.



Serena started to push up from Fred’s chest and whispered, “thank you.” Into the hollow of his throat. Her voice was huskey from the damage to her throat and Fred could not keep from thinking how erotic it sounded.



George helped her sit up and she winced as her weight settled onto her backside, he draped an arm around her shoulders as she leaned back against his chest. “Kinda gave us a fright there.”



He felt her head move against his shoulder and his eyes rolled back as her huskey voice whispered “sorry.”



“Well, we very well couldn’t let you die…”



“..yeah, can you imagine the detention we would have gotten for that.” Fred finished the sentence and Serena managed a weak smile.



Fred was lying prone on the floor and the reality of his discomfort was evident to George, and most likely had been to Serena too. He tried to think about her in the way she usually was, the bitchy Ravenclaw who had gottent them detention in the first place. But all he could think about was her snuggled against him, and the way it felt when she arched away from the pain in her back. He covered his eyes and let out a sigh as he sat up, reluctantly. He pushed himself against the opposite shelf and stared at George and Serena.



She sat up a little and Fred saw the three rings of bruises around her neck. He leaned forward and touched the darkest one, his finger tracing it around as far as he could and then back the other direction. Her head tipped back and her eyes fluttered shut as his fingers soothed the tender skin. He dipped his finger in the jar and smoothed the liquid along the purple areas.



He put his hand on the little button holding the remains of her shirt together, “may I?”



Serena’s eyes darted up at George and he remembered her robe. He picked it up and she leaned forward as he wrapped it around her exposed back and shoulders. Fred undid the little buttons running down the front of her white shirt with trembling fingers and then pulled the material apart. He sucked in his breath as he saw the bruises criss crossing her chest and torso.



George looked over her shoulder as Fred began to rub the liquid into the bruises. He dipped his fingers into the jar and began to help.



Serena leaned her head back against George’s shoulder and shivered at the sensation of the twins both touching her. The liquid was cool to the touch and her nipples hardened when the cold from the dungeon touched the wet areas. Her eyes were closed and she did not see the look that passed between the boys.



Fred swalloed in an attempt to control his body but was too far to stop it. George looked at him and then slowly slid his fingers against the plastic clasp holding her pink cotton bra together. It rested in the valley between her breast and disconnected with a little snap. He paused to wait for her reaction but she only stilled for a moment and her breathing sped up. He slowly pulled the material apart and Fred moaned when her pert breast, marred by a thick purple band, were revealed. George cupped them in his hands and began to rub his thumbs across the erect nipples. He glanced up to see Fred watching him, his breathing a bit labored.



George nudged Fred with his foot to get his attention and then nodded towards Serena. Whith her breast still cupped in George’s hand, Fred bent forward and took a soft pink nipple into his mouth. She gasped at the contact but then slid her hand to the back of his head to hold him in place.



He flicked his tongue back and forth and grazed the sensative skin with his teeth while he slid his hands up her thighs. He massaged the muscles lightly as he travled further up her legs. When his hands met at the juncture of her thighs he rubbed his thumbs across the sensative nub, causing her hips to jerk forward and a low moan to escape her injured throat.



Fred gathered the top of her knickers in his hands and slid them down, her hips lifted and he pulled them off. He removed her other shoe and tossed it to the side. He ran his hands back up her legs and pushed them upward as he went. His head dipped and hovered over her, his warm breath carrasing the sensative skin.



George began to knibble and kiss the skin on her neck and jawline, she turned her heard towards him and he captured her mouth in a deep kiss. His tongue slid along her lips and as it slipped into her mouth, Fred’s slipped into her cunt.



Her hips arched, forcing him deeper and she felt him smile against her skin. She had one arm up around George’s neck, twining her fingers in his hair. The other hand was resting in Fred’s hair. George continued to assult her mouth while his hands rubbed and carrased her breasts.



Fred was driving her to the brink, his tongue was darting in and out and then swirling around the tight nub of nerves. His teeth raked across her and she jerked her head away from George’s kisses. Both hands grasped Fred’s head and she pulled him away. He legs were trembling and her hands were shaking as she reached for the belt around his waist.



Fred shuked his pants quickly and then lay back on the cold floor. He shivered but not from the cold, as Serena crawled on top of him. She bent forward and he eagerly accepted the kiss. His hands carrasing her hips and backside as she hovered over him.



George growled low in his throat as he watched Serena hover over Fred. His own cock was hard and throbing watching the exchange. He crawled forward and paused before grabbing his brothers cock and then guiding Serena’s hips, as soon as the two made contact she impaled herself on him. George moved back and began to undo his own pants. He moved behind Serena and gathered her to his chest, his own erection riding low on her back.



Fred thrust upward and then he felt Serena’s body begin to quiver. She began to pant as she rode him and then threw her head back against his brother’s shoulder as her muscles convulsed around him. Her nails dug into George’s bare thighs and with one last thrust Fred’s cock exploded inside her and he pumped himself empty into her.



Serena leaned into George’s embrace as Fred’s cock relaxed out of her. George slid his finger into her and used his brothers cum to lubricate her arse. He slowly worked it around and then bent her forward over Fred.



“Is this okay?” He whispered hoarsley against her ear and then slid his tongue around the outer shell.



Serena shivered and then nodded her head. George’s eyes closed and he trailed his tongue down her spine. He placed a feather light kiss on each scrape as he went.



George wrapped his arm around her waist as she threaded her fingers into Fred’s hands. She rested her head against his warm chest and he kissed her temple. Behind her George moved slowly into her tight arse, he stopped when he body stiffened and then he pulled back, both movements nearly drove him mad. He used his finger and Fred’s cum to lubricate her some more and then moved back in.



He moved further in this time and the slowly pulled back, he didn’t penetrate far but the tightness was more than her needed. He felt her body begin to rock as he he pushed in one more time and then his body stiffened, Gasps of surprised desire erupted from her and the sound drove him over the edge, he pumped himself into her and he felt the very faint tremors of her orgasm.



Serena lay across Fred’s chest as George dressed himself, just as he tightened his belt they heard the door open. She pushed up and Fred quickly pulled his pants on.



“What is going on down here?” Professor Snape took in the sight of Fred and George huddled over Serena. Her bare back was towards him and she was curled in on herself. When George sat up he saw that her back was covered in scratches.



“I was attacked.” Serena flinched as Fred touched the deeper cut with the cold Mertlap.



“By which one?” Professor Snape hissed out the word as he bore down on the three of them.



George jumped to his feet and pointed towards the back wall, “By that bloody plant your growing down here.”



Snape pulled Serena to her feet and eyed the three of them carefully. While it was obvious that she had been attacked he knew that something more had happened. What he didn’t see, as he walked away with Serena, was Fred slip the pink cotton knickers into his pocket.
