A Prank Gone Wrong
by Cordial Knot
I wrote this story, and most of my other fan fiction, before I made the Cordial Knot Collection. This is my only story without mind control, but "control" is still a strong element so I'm posting it anyway. One of the perks of running this site.
******************************************************
PART 1: MEGAN’S PRANK
Megan sat in her room, hunched over her desk. Her parents had taken Josh upstate somewhere for the weekend to see a two-day magic show. They were planning on having a “bonding” trip with her and one with Drake too, but Josh was first. Megan had decided to pull a big prank in Drake this weekend.
She had managed to get her hands on a muscle relaxant gas through a friend. Once inhaled, all of a person’s muscles would be extremely weak in less than ten seconds. Megan’s plan was to spray Drake and, once he was too weak to move, drag him on to the roof of their house. She was going to tie him to make sure he didn’t fall, of course, so she had various lengths of rope laid out around her on the floor.
Right now, Megan was transferring the gas from its canister to a spray bottle. She had to make sure she could control the direction of the gas so that she wouldn’t be affected. Megan carefully unscrewed the canister and held it up to the mouth of the spray bottle. The pressurized gas streamed into the bottle without leaking.
“Hey Megan, could I borrow a-”
“Drake!” Megan shrieked. She had been so focused on not spilling the gas that she hadn’t heard him open the door. Megan jumped out of her chair, trying to shield the ropes, canister, and bottle from Drake’s view. As she did, the canister fell from the mouth of the spray bottle.
“Get out!” Megan screamed. Drake slammed the door and bolted down the hall, he had made Megan mad before and she always made him regret it.
Megan locked her door before going back to her desk. She felt a little dizzy. Glancing down, she saw the muscle relaxant gas was being leaking from both the canister and the spray bottle. “Shit.” She could already feel her arms and legs weakening. Megan’s legs gave out and she fell to the floor. Struggling up to her hands and knees, Megan tried to crawl to her window. If she could open it, the fresh air would dissipate the gas. But if the gas took full effect before she could, she wouldn’t be able to move for an hour at least.
Her window was barely seven feet away but with each second her strength was eroding. Megan’s desperate crawl slowed to a few inches of movement. Three feet away, she lost all of her strength and could only stare upward at the window.
The gas didn’t affect her mind at all, it just relaxed every muscle in her body. So, Megan was completely aware of the fact that, a few seconds later, she lost control of her bladder and had an accident right on her carpet. With the gas now at full effect Megan couldn’t even call out for help, the muscles in her jaw barely had the strength for a mumble.
******************************************************
Drake paced in the living room downstairs. He didn’t know what he had done wrong. But he knew that if he left Megan angry, he’d probably find a snake in his bed tonight. Thinking of the outrage on Megan’s face, Drake amended: he’d probably find a poisonous snake in his bed tonight. Summoning his courage, Drake marched back upstairs to apologize for whatever he had done wrong.
Drake knocked on Megan’s door. “Megs? Are you still in there?” Hearing nothing except, perhaps a groan, Drake tried the door but found it was locked. Getting worried, Drake ran downstairs and grabbed the master key from the kitchen to unlock Megan’s door.
Drake opened the door and saw Megan lying stretched out on the floor. Drake smelled something flowing out of the room, diluted into the rest of the house. Megan was lying down, still reaching out toward the window, which was several feet away. Drake rushed over to her, thinking she might be hurt or even dead. But her eyes were open, if slightly out of focus.
“Megan, what happened?”
Slowly, as if it took her mouth a while to form the words, Megan explained. “Ih wus uh pwank. Bweathed gas. I loss musul conwol. Lasts uh hour.”
“Wait,” Drake said, after puzzling out her meaning, “you were going to do this to me?”
Megan tried to scowl, but her facial muscles were still slack. “Uh pwank.” She repeated, slurring the words again.
“I don’t think that I should help you, then.” Drake stood up and walked towards the door.
“Dway, please. ” Unable to turn her head, Megan was mumbling to the wall in front of her.
Feeling a little pity, Drake turned back. Then his thoughts of pity evaporated. He hadn’t noticed initially because of his worry for Megan. From the doorway, Drake could see right up Megan’s skirt. She was wearing green panties which contrasted sharply with the pale skin of her legs. Drake noticed a dark stain on the carpet around Megan’s skirt and knew that she had had an accident, although he didn’t know why. Every twisted thought Drake had ever had about his sister came back to him as he watched her, helpless on the floor.
“You know, Megan,” Drake said, bending down to get a better view of his little sister’s panties. “I guess that was a little mean, I’ll do what I can to help.”
Still unable to move in any way, Megan breathed a sigh of relief.
PART 2: LET ME HELP YOU, MEGAN
Drake moved closer to his sister, kneeling on the floor behind her.
“Hey, Megan, it looks like you had an accident. Don’t worry, though, until you can move again I’ll take care of you.” As he spoke, Drake tugged Megan’s wet skirt down her long legs and tossed it aside.
Megan mumbled “No sop.” But she was unable to do anything to actually stop Drake. Drake pulled down Megan’s drenched panties, throwing them on top of her skirt.
“You’re still really wet, Megan. Mind if I use your towel to dry you off?” Ignoring her weak protests, Drake grabbed her bath towel from its hook and began rubbing her pussy and her firm butt. Still unable to move, Megan could only stare at the wall as her brother played with her.
“There you go, all dry.” Drake slapped her butt lightly. “But you’re not really clean yet, are you?” Drake grabbed Megan’s waist and rolled her over so that her hairless pussy was facing up at him. With no strength, Megan’s head lolled to the side, leaving her staring at her closet.
Drake leaned down and began exploring her pussy with his tongue. He was well practiced from a seemingly endless succession of girlfriends. He alternated between fast licks and slow. Megan began to cry. She knew this was wrong but she couldn’t stop her body from becoming aroused. After a few minutes, Drake had coaxed his little sister into her first orgasm. He then spent several happy moments licking up her juices.
“Darn, Megan, I spent all that time trying to clean you up and then you go and have another accident. I obviously wasn’t thorough enough; let me try a deep clean. ” Drake pulled off his jeans, exposing his already hard cock. He brought it to Megan’s folds and paused to see her reaction. Megan’s face was still slack from the muscle relaxant she had inhaled, but Drake could see the shock in her eyes that came from realizing that her brother was about to take her virginity.
Drake began introducing his cock to her pussy. He started with small, shallow thrusts to tease her. Then Megan moaned a little as he bumped against her hymen. Not wasting a breath to reassure his sister, Drake suddenly thrust his entire cock deep into her. Megan gasped from the pain, but was unable to do anything else. After a few minutes of thrusting, Drake released into his little sister and she unwillingly came for a second time.
Panting, Drake smiled at his sister. “Megan, you are just determined to stay dirty, aren’t you? First you have two accidents then, when I try to clean you up, you go and bleed everywhere.” Megan sobbed in reply.
“Well, I made a promise to take care of you until that stuff wears off. I’m going to get you clean if it’s the last thing I do.”
PART 3: IT’S OKAY FOR SIBLINGS TO TAKE BATHS TOGETHER
Drake pulled Megan’s limp body up off the floor and threw her over his shoulder in a fireman’s hold. He carried her down the hall to their common bathroom and set her on the closed toilet seat to turn on the water. With no muscle control, Megan immediately slouched to the side and almost fell into the bathtub.
“Hang on there, Megan,” Drake said, catching her. “We can’t take a bath with our clothes on.” He steadied her and pulled her shirt up over her head, revealing a white training bra.
“You know you probably won’t need a bra for another year,” Drake told his sister conversationally, tugging it off as well. “Actually, I take that back. You’re breasts are coming in pretty nicely.” Drake twisted a nipple just hard enough to get a response from Megan.
“In you go.” Drake lifted Megan into the tub and let her lean against a wall. Drake quickly stripped and got in the tub with her. While waiting for the water to finish filling, Drake positioned his sister so that he was straddling her young body. Drake sat at one end of the tub and put Megan between his legs so that her firm but was pressed nicely against his hardening cock.
“Alright, now let’s get you clean.” Drake ran his hands over his little sister’s body, pulling her back into his arms. He played with her tiny breasts, massaging them and twisting her nipples until they puckered. His hands roamed all over, but kept coming back to her pussy. With the skill born from practice, he teased Megan into two more orgasms. On the second orgasm, Megan twitched a little. Not much, but her hips bucked instinctively as pleasure overcame her.
“Hmmm… it looks like the effects are going to wear off soon. Why don’t we head back to your room and make sure you’re comfortable for when you’re back to normal.” Moving quickly, Drake stepped out of the bath and toweled off. He pulled Megan out and dried her off, somewhat less quickly because he kept getting distracted. Throwing Megan over his shoulder once again, Drake walked back to her room.
PART 4: ARE YOU COMFORTABLE?
Drake dropped Megan on to her bed and glanced around her room. He noticed the ropes lying in a pile next to her desk.
“What’s with all the rope, Megs?” Drake asked. Then he grinned, “No don’t tell me, I know you can’t talk very well right now. Let me guess: you’ve actually got a bondage fetish, right?” Megan tried to shake her head but, even though the gas was wearing off, she was still too weak to do even that. Drake picked up the ropes and brought them over to Megan’s bed.
“Like I said, until you’re back to normal, I’m going to take care of you. If bondage is your fetish, I won’t judge you.” That said, Drake began tying Megan’s wrists and ankles to her own bed. He left her facing up so that he would have full access to her breasts and pussy. He tied the knots fast enough to leave no doubt that a few of his girlfriends had had a bondage fetish, or perhaps it was him. Once Megan was secure, Drake went back over to her desk and grabbed some tape as well as her panties from the floor. Since Megan still had almost no muscle control, it was easy to stuff the panties into her mouth and tape it shut.
Megan’s strength was still coming back, but now it was too late to matter. Drake straddled his little sister, kissing her and playing with her breasts until he was hard once again. Drake shifted down the bed and began forcing himself inside Megan again. Tired as she was, it took almost an hour before Drake could get her to orgasm, but he considered it time well spent.
“You know, Megs,” Drake said as he was getting dressed. “At the rate that you keep getting yourself dirty, I’ll probably have to give you another bath soon. Of course I’ll need to find more of that gas, first.”
PART 5: THERE’S ALWAYS TOMORROW
It was past midnight, so Drake started getting ready for bed. He texted his girlfriend of the week, saying that he was breaking up with her because he had found someone else.
Josh and his parents would be gone all weekend on their bonding trip. Megan was still tied up and it was only Friday night. Drake couldn’t wait to have some more “bonding” time with Megan tomorrow. Of course, he’d have to remember to give her a few of the roofies that he kept for his girlfriends. Otherwise things could get…awkward…when the rest of the family came home.
