Kim Possible Porn Story: It Was An Accident The First Time!

It Was An Accident – The First Tim!
It was another Saturday night babysitting the tweebs, and Kim had had it up to here with them. Her Mom and Dad were out for the night to a dinner and show, which meant she had to look after her brothers…again! They were old enough to go to high school now, but not old enough to be left alone. Kim sighed. Well, she had to agree with the latter part of her statement. Ten minutes after her folks pulled out of the garage, there had been a minor explosion in said garage. It turned out the tweebs were trying to improve on the J47 rocket fuel that they had “borrowed” from their father. Back to the drawing board on that one. Luckily Dad always kept a half dozen full fire extinguishers in the garage for just such ann emergency. While Kim had been putting out the fire, the tweebs had retired to their room to work on thei rown pan dimensional vortex inducer. Lucklly Kim had put a stop to that, though the tweebs were going to need a new dresser as theirs had been sucked into the nano black hole they had created.
At long last the tweebs were in bed and asleep so Kim could relax. She carefully locked hte bathroom door to prevent any spying by the tweebs. A long hot shower was what she needed to calm her nerves. Kim began to undress. She peeled off her standard green tank top and her blue capris. Then Kim unhooked her bra and let her breasts spill out. She couldn’t help but be pleased at the filling out of her breasts (finall!y). She had gotten tired of being the smallest chested girl in school and the flat chest comments from Bonnie when they showered after practice. Finally, Kim slid offher panties to expose her fuzzy red bush. Carpet matches the drapes, she thought, mentally mimicking Bonnie’s sarcastic voice. Kim adjusted the water temperature and stepped into the shower, sighing with contentment as the warm water cascadd down over her naked body. Kim washed her long red hair and then set to work on the rest of her body. She was soaped her pleased and her entire body. Kim moaned softly as she touched and caressed her breasts. It was nice not to look quite so much like some cartoon character in a PG movie where the heroine wasn’t allowed to have a chest or (gasp) show cleavage. Kim felt her nipples harden as she ran her hands over her breasts and she blushed even though there was no one there to see what she was doing. She had touched herself before in the shower, but it always made her a bit uncomfortable as if she was doing something diry. Despite this, Kim’s hands were just straying lower between her legs with thoughts of a little more fun when she heard a crash from her room. The tweebs!
Hurriedly, Kim shut off the water and wrapped a towel around her body and dashed for her room, her hair still wet and plastered to her shoulders and back. Inside her room, she found the tweebs in their pyjams rumaging through her stuff. Tim had her Kimunicator in his hands and was about to remove the trilithium power core.
“Tweebs!” screamed Kim in exasperation. “How many times have I told you to stay out of my room and to leave my stuff alone?”
Tim looked up unphased. “Aww Kim, we were just going to borrow your battery again. We needed somethign with more power to run our pan dimensional vortex inducer version 2.”
“What? So you can suck the whole house or the whole city into a bigger black hole?” demanded Kim as she advanced on Tim.
“Don’t worry, we got the bugs all worked out,” assured Jim. “We can use a controlled black hole to clean yard and garages. We’ll charge big bucks and get rich.”
“Give me that Kimmunicator,” growled Kim and lunged at Tim who dodged and began to run around the room. Kim gave chase, hopping over the bed in pursuit of Tim who tossed the Kimmunicator to Jim. The chase continued with more passes back and forth between the twins and with Kim getting more and more frustrated.. She made a final desperate lunge at Jim on top of her bed and snagged him, pinning him to the bed, but only after he had tossed the Kimmunicator to Tim once again. Unfortunately for Kim, the lunge hd also dislodger her towel and she found herself notally naked and sprawked on top of her brother, her hands holding his wrist pinned to the bed like a wresting match.
“Ummm, Kim?’ said Jim meekly as he stared up at his sister’s beautiful bare breasts.
“What?” snapped Kim not yet realizing what had happened in her anger. Now that she had caught one of them, she wondered what to do about it. For all her talk about wanting to become an ony child, she really didn’t want to hurt her brothers…well, not much anyway.
“You lost your towel,” said Jim in a voice that sounded rather odd.
Kim gasped and glanced down at her naked boyd, all wet and soapy from the shower. Her face blushed as red as her hair and she let go of Jim’s wrist and started to push herself up off him and the bed. Unfortunately, her wet hands slipped on the wet sheets and she collapsed forward onto Jim. Her breasts were right at face level and somehow she ended up with one of her nipples in his mouth. In a pure reflex action, Jim’s mouth closed and he began to suck on Kim’s hard nipple.
“Ahhhhhhhh,” moaned Kim. “Stop that,” she ordered him and tried to push herself up off him again.Her body was rubbing against her brother and she paused in shock when she felt something hard poke her between her legs. Kim looked down and swallowed hard as she saw Jim’s hard ltitle cock poking out of the opening in his pyjamas and actually rubbing on her pussy lips. It would take only a bit of pressure for his cock to slide inside her!
“Oh my god, don’t move. Don’t breathe,” ordered Kim as she tried not to panic. She just had to get up very carefully and everything would be fine. She sure as hell didn’t want the first cock inside her to belong to her tweeb brother. Kim had some vague plans for that being Ron’s job at some point in the future, maybe at college or something.
“What’s wrong Kim?” asked a confused Jim as he lay there with his sister’s weight on top of him. Her breasts looked so nice right htere in his face and it had felt good sucking on her nipple, somehow evoking warm feelings he hadn’t felt for years. Her body felt so warm and soft against his and it seemed to be doing things to him. That is when her noticed he had an erection. Cool, when it had been discussed in Health class, he hadn’t understood the big deal about it, but now suddenly the lesson took on a new importance. “Hey Kim, I got an erection,” he blurted.
“I know that!: snapped Kim as she carefully began to push herself up and off her brother.
Meanwhile, Tim had been standing by the door watching and not realizing what was going on. He stared at the bed, looking at his naked sister and felt his own penis stir in his pyjamas for reasons he was not sure about. He did know he wanted to distract Kim so his brother could get away, and with a yell he charged at the bed and jumped onto Kim’s back.
Kim was unprepared for 80 pounds of tweeb to land on her back and she collapsed under the weight. Jim’s cock had been right at the entrance to her pussy and the weight of Tim on her back impaled her on him. It happened to fast for her to stop it. The cock sliped betwen her pussy lips and into her. Kim gasped and her eyes went wide with shock. In one horrible moment, both she and her brother were no longer virgins. She could feel his cock totally sheathed inside her and his gaps of pleasure as her velvet walls clenched his hard young dick in their grasp.
“Get off me! Get off me!” screamed Kim in panic as Tim continued to bounce up and down on her back. But Tim still didn’t realize what was going on and what he had accidently done to his sister and brother.
“Giddy up horsy,” he jeered at Kim and yanked at her long wet red hair as if it were reins. Tim’s rocking motion was quite effectively pushing Kim up and down onf Jim’s cock. This was drawing moans of pleasure from Jim as his cock slid in and out out of his sister’s tight pussy. To make matters even worse, the feel of a naked girl under him, even if she was his sister was stimulating Tim and his cock too had come erect and poked out of his pyjamas to rub on Kim’s ass and back as he rode her.
Jim didn’t know what was happening to him, other than his cock felt REAL GOOD inside of his is sister and he liked the feel of her warm body on top of his. Jim’s eyes rolled back in his head and he gasped “K..Kim I feel strange. It’s my thing, it is really feeling good and something is happening to it.”
Kim was frantic with panic as she tried desperately to push herself off her brother and get Tim off her back. All her squirming and wriggling thugh seemed to do nothing more than accidently stimulate Jim even more. She could feel his cock inside her and Tim’s rubbing on her ass like two hot pokers. But she had to stop this before the unthinkable happened. But before she could extricite herself from the tweebs, she heard a loud moan and then she felt a jet of liquid shooting nto her pussy.. Kim froze in shock, feeling her brother cumming inside her and her mind reeled. Oh damn, this was so sick and wrong! Kim felt several more blasts of cum hitting the walls of her pussy and wondered how such a stupid accident could have happened. With a grunt Kim finally managed to dislodge Tim and roll off of Jim. She looked down between her legs and saw some of her brother’s cum trickling out of her pussy to form a puddle on the sheets on her bed. “This. This is not good,” she muttered.
“Wow, it sure felt good to me,” moaned Jim as he stared at his naked sister.
Tim also stared at his sister and brother and the light of realization finally came on. “Cool, I think you just had sex,” he said and high fived his twin.
“Hicka bicka boo”, said Tim.
“Hoo shaw!” agreed Jim. “That was cool Kim.”
“It was not cool!” screamed Kim. Brothers and sisters are not supposed to have sex. Didn’t they teach you that in Health class? It is called incest and it is sick and wrong”
“It sure felt good,” disagreed Jim. “Besides, we were busy designing rockets when Mr. Barkin was talking about that kind if icky stuff.” .
“Well maybe you should have paid more attention in class and you wouldn’t have ended up fucking your own sister!” shouted Kim angrily.
“Is it my turn now?” asked Tim as he saw his cock poke out of his pyjams. It was pointing right at his sister.
“No!” said Kim angrily. “What happened was an accident. A silly stupid accident.”
“But I want to try it,” protested Tim. “If Jim got to have sex with you, it is ony fair that I do too.”
“No way tweeb,” said Kim suddenly realizing she was still naked and grabbing a pillow to hide behind. “You shouldn’t even have seen me naked and I certainly shouldn’t have seen those,” she finished pointing at the two hard cocks of her brothers.
“Aww please Kim,” begged Tim as he moved closer to the bed, his cock pointing right at her like a compass needle to true north. “my thing is so hard it hurts!”
Kim considered him and his hard cock for a few seconds. I shouldn’t even be thinking about this, thought Kim, but it’s not like I am a virgin anymore and it doesn’t seem fair to let Jim do it and not Tim. It’s incest said her inner voice. Yes, but I already committed incest once, so is twice any worse she replied. Also, it had felt rather good to have a cock inside her, much better even than masturbating. Kim made up her mind and dropped the pillow. “Ok, you can do me too,” she said and laid back on the bed with her legs open.
“Hicka bicka boo,” said Tim pulling off his pyjames and scrambling up on the bed and between Kim’s spread legs. Then he paused. “Er, what do I do?”
Kim sighed and reached down to frame her pussy with her hands. “Put your cock in here,” she instructed him. “Since you weren’t paying attention in Health, it is called a vagina or if you are vulgar like Bonnie, it is called a pussy or cunt. Your thing is called a penis or again if you are Bonnie, it is called a dick or a cock. When you have sex with a girl, your cock gets hard and you put it into a girl’s pussy. That is called fucking.”
“Cooh,” replied Tim. “I want to fuck you Kim. I want to fuck you real bad.” With a little fumbling and some help from Kim, Tim managed to slide his cock inside his sister’s pussy. “Now fuck me,” instructed Kim. “Move your hips so your cock goes in and out.”
A look of pleasure came over Tim’s face as he began to move in and out of Kim. A similar look of pleasure came over Kim’s face as she felt her pleasure growing. The teen hero cupped her breasts and played with her hard nipples as her brother enthusiastily slid his cock in and out of her pussy. Kim turned to Jim, “here you wanted to suck on these then do it” and she offered him her breasts. Jim who was hard again quickly moved over to his big sister and began to suck and slurp on her tits.
“Ahhhhhhhhhhh I think I am going to do the same ting Jim did,” moaned Tim as he felt a strange sensation in his cock and balls.
“Ahhhhhhhh, fine, just keep going and don’t stop,” moaned Kim as she felt her own orgasm approaching. ‘Yes, that’s it, fuck me you little tweeb. Fuck your big sister and cum inside her!” A few strokes later, Kim felt the second blast of tweeb cum in her pussy as Tim came Kim gave a strangled cry of pleasure and her entire body shuddered as she too came with the strongest orgasm she had ever had. For several minutes, Kim just laid there, slowly coming down from her climax. Wow, she thought, she was going to have to try this again, she had never felt anything that intense before.
“Ummm Kim, we are still hard,” said Jim indicating his own stiff cock and Tim’s.
Kim contemplated the two stiff cocks. It was all so sick and wrong, but there were other things that Bonnie and the other cheerleaders had giggled over in the locker room. “Let’s try something else,” suggested Kim.
“What?” aske Jim as stood beside the bed.
Kim got them both to lay back on the bed with thei rcocks pointing straight up in the air. She crouched over them and lowered her mouth onto Jim’s cock. Her heart was pounding wildly as she slid her lips around the hard tube of flesh and began to suck and lick it. She was rewarded with a loud moan of pleasure from her brother and after a few seconds she switched to Tim and got a similar reaction. Kim alternated her mouth between the two cocks, using her hands to jerk the one she was not sucking on at the moment. Well, now I know what a blowjob is like she thought as she sucked on her brothers’ cocks, experimenting with using her tongue to lick them at the same time. She remembered Bonnie snickering about how you would have to “spit or swallow” at some point and Kim decided that she wanted to try swallowing. I mean, what was the point of doing all this and then just spitting the stuff out? She wanted to see what it tasted like.
“Kim, I think I am going to do that thing again,” warned Jim.
“Me too,” moan Tim as he felt Kim’s soft wet mouth gliding up and down his cock.
“Go right ahead tweebs,” encouraged Kim. “Cum for me. Cum in my mouth.” Kim felt Tim’s cock trembling in her mouth and she wrapped her lips tighter around it, licking frantically with her tongue at the tip. There was a sudden spurt of warm liquid into her mouth and another and another. The red haired teen took her mouth off Tim’s cock and let a last spurt of his cum hit iher in the face. She rolled the mouthful of cum around in her mouth for a bit, savouring the taste and the feel of it and then swallowed. Mmm, kind of nice she thought and turned to Jim and took his cock back in her mouth. A few seconds later, she was rewarded with a second mouthful of cum that she savoured and swallowed.
“That was awesome,” moaned Tim.
“Double awesome,” moaned Jim.
“That was called a blowjob,” said Kim as she used her fingers to wipe some of the cum from her face and then licked them clean.
An hour later when her folks got home, they found a freshly showed Kim sitting on the sofa watching tv while her brothers were (for once) sound asleep in thei rbeds and smiling as they dreamed.
“Someone took good care of her little brothers,” said Mrs. Possible with a smile.
“Yes, sometimes they are hardly evil at all,” agreed Kim with a smile and she wondered if she could talk her parents into going out again next weekend. She wanted to try it all again, and maybe a few other things as well that she had heard about in the lockerroom.
The End
