“Hey, look at that one,” Jerome said, pointing to one of the cheerleaders practicing in the field, “now that one could make any swinging dick stand up and cheer.”
“Nigger, you say that about every blonde,” Spike put in, chuckling, “but I’ll give you this, Kelly’s rape bait fo sure. Got a booty as tight and fine, and bouncey as you could ever want, and those titties of her’s be ripe enough to pluck a year ago.”
“Who you call’en Nigger, Nigger?” Jerome punched his friend playfully in the right shoulder. “And don’t go thinking you can rape that bitch and not get yo ass whipped by that twin big brother of hers either. That’s one white boy who be a real bad ass mutherfucker.”
“Yeah, Casey’s a screwy one alright. Got as many muscles as he do brains. Who’da ever thought, a jock football player/honor student? Hell, that ain’t natural.”
“Fuck that. What ain’t natural, is that hot ass bitch sister of his.”
“Yeah, what a dick teasing wet dream she turned out to be. Might be worth an ass whoop’en for a taste of some of that.”
“You know, maybe we can do it, and not get a whoop’en,” Jerome thought outloud, and for the first time in years, Spike was listening to him.
“What’s that you’re working on?” Asked Mr. Chumly, Casey’s science teacher.
“Something for my science project, sir,” Casey replied.
“Nothing explosive in those chemicals, is there?”
“No sir, take a look, it’s all in my notes here. I just need one thing. A hair folicale, and the formula will be complete.”
“I look forward to seeing the results Casey,” Mr. Chumly said, and as he walked out, added; “Just remember to close up on your way out son, and good luck.”

“Thank you sir,” Casey said over his shoulder, totally absorbed in concentration, “but if Kelly will lend me a lock of her hair now……I’ll have made the biggest discovery in genetics since cloning……”
“…..biggest what since cloning?” Kelly asked, entering the lab all sweat soaked from cheerleading practice. “And how come you aren’t at football practice?”
“Not that it matters Kelly, but the coach gave me some time off so that I could finish this project of mine for the science fair. Not that he needs me, I’m just the second string quarterback on the Junior Varsity team.”
“Only because you don’t want to be on the first team,” his sister retorted, “and don’t think for a moment that the coach doesn’t know it either. And…..hey! What’d ya pull my hair for?”
“I need it for my experiment.”
“Well next time, take it from my hair brush, okay? And as I was about to ask, just what is it you are working on here brother?”
“It’s a special formula I’ve invented.”
“What’s it do?” Asked his sister, suddenly inquisitive.
“How good can you keep a secret?” Casey inquired in a hush, hush voice.
“Better than you ever could, and you know it.”
“Okay, okay, just keep your voice down. This is top secret,” and he looked around to make sure no one was nearby, “it’s a…well,” and suddenly Casey was blushing, “it’s a chromasome destablizer.”
“And now for us incredibly inane,” Kelly said, crossing her arms, and tapping her right toe on the floor.
“Well, it’s a little embarassing really, especially for a football jock like me. I mean, what would people say if I told them that I’ve invented a means of gender transferance?”
Kelly stood there for a moment, looking quite pissed off, and perplexed, and then it suddenly hit her what her brother was suggesting, and she began to giggle, then laugh, then lost all control completely crumpling to the floor in fits of hysterical laughter. It took a while for her to collect herself, and that was probably because of the look of stern shock on her brother’s face everytime she glanced his way, but eventually she caught her breath.
“Sorry Casey,” Kelly chuckled her last, “but for a moment there I got this image of you in one of my cheerleading outfits, and well…..”
“Yeah, but would you laugh if you looked in the mirror dressed in my football uniform?”
“Huh?”
“This formula works both ways sis.”
“You mean?” And all laughter died instantly in her voice.
“Well, it was just a thought,” Casey replied, “I mean, if I became you, you’d have to become me, or people would become suspicious with two of you around, now wouldn’t they?”
“How long would it last?” Kelly asked anxiously.
“That’s the problem.”
“What problem?”
“I just don’t know how long. I mean, it could be that it would be permanant, or that we’d have to take the formula in reverse to change back. I just don’t know.”
“You know, mom and dad are going to be gone this weekend. I think we need to talk about this on the way home, Casey, don’t you?”
“Why?”
“Because, for one thing, I want to know what it’s like to pee out of a spout instead of having to squat all the time. I mean, how do you aim the damn thing?”
“Oh shit!” Casey gasped. “I hadn’t thought of that. I’m going to have to think this over some more. What if I…you…I, start to…..to bleed?” And then Casey really started to shake all over as he barely whispered out, “Or worse yet, what if we got knocked up?”
“What do you mean, we?”

Kelly laughed all the way home over that last comment. To her way of thinking, guys had it made physically, and she was looking forward to her side of this experiment. She knew she was a virgin, hell, who didn’t? But her brother was under no such constriction, as a guy he couldn’t get pregnant, and he had just as much as admitted that he wasn’t going to give up his sex life even if he became a girl, or more specifically, her. It wasn’t until she got home that she realized that if they did change places, her brother would see her naked any time he looked in the mirror, if they did switch. She wasn’t quite sure why that turned her on, making her pussy moist, but it did. So much so, that she doubled back to sneak up on Casey just as he was putting the two bottles, one tinted blue, and the other pink, up on a bookshelf behind his favorite trophy. Since Kelly had seen him put her hair in the pink one, the blue formula had to be the one to change her into him. Now all she had to do was wait until he left his room to sneak in and steal the fomulas.
Kelly’s plan was to put half of each formula into their dinner milk, the pink into Casey’s, the blue into her own. Their parents had left an hour after the two siblings got home, and received their usual instructions for no parties, no drinking, and no friends staying overight while they were gone.
“Here’s your milk,” Kelly said putting a glass of slightly off white liquid in front of her studious brother, who had his head buried in a book, “and here’s some chocolate chip cookies mom made for us.”
“Thanks Kelly,” Casey said, absentmindedly taking a cookie, and drinking the milk, “let me know when it’s 7pm.”
“What happen’s at 7pm?”
“I’ve gotta call Jinny. I promised to take her to the mall tomorrow, but I may need to back out. Dad gave me an errand to run tomorrow.”
“What’s the errand?”
“I have to pick up Bear from the vet’s,” Casey replied, referring to the family pet, “dad dropped him off for his shots tonight.”
“I see,” Kelly said, taking her milk and several cookies with her up to her room to study.
She waited, and waited, but nothing happened by the time midnight came around so Kelly took another shower, got into her favorite pink teddy nitey, and went to bed. Her last thoughts were; that it was a shame the formula didn’t work, but at least her brother wouldn’t find out right away that she’d stolen the two bottles, and she could put them back when Casey went to pick up Bear in the morning.

************

Casey woke up in his bed sprauled out in his underware with his head laying on his notebook, and his head throbbing as if he’d been into his dad’s scotch. His throat was parched, and his tongue tasted like he’d licked Bear’s furry balls. Which reminded him that he had to get a move on if he was gonna pick up Bear from the vet’s and take Jinny to the mall by noon.
Slipping out of bed, Casey made his way down to the kitchen in his bare feet to make some coffee. After he got the pot started, he headed up to the bathroom to take a leak. Lifting the toilet seat, he reached into his boxer shorts to pull his penis out, and suddenly froze. It was gone! His cock and balls were missing! Missing?!
Casey looked down then, and got the second shock of his life. He had breasts poking out of his T-shirt. Boobs!? And long blond hair tumbled down on each side of his face that tunnel visioned his focus making it seem as though he’d grown two udders on his chest, at first startling him, before a quick look in the mirror next to the toilet over the sink had him looking at the reflection of his incredibly beautiful sister Kelly’s image through her eyes.
“KELLLLLLLLLLLYYYYYYYYYYYYY!”

Kelly woke with a start sitting straight up in bed, and her eyes went wide when she caught sight of the hairy long muscular male legs sticking out of her pink panties, not to mention the uncomfortable cramping bulge that would not allow her thighs to come together without a great deal of pain.
“What the?” Kelly’s sudden alto tones frightening her more than her eye’s reality could have as she realized what had happened in her sleep.. “CAAAAASSSSSSEEEEEEEEEYYYYYYY!”
Casey came running into Kelly’s bedroom and stopped dead in his tracks. His nightmare was getting worse by the second as there he was in Kelly’s bed wearing Kelly’s night clothes, and looking like something out of the Rocky Mountain Horror Picture Show’s drag queens.
“Shit!” Casey said with Kelly’s voice. “What have you done to us Kelly?”
The smile that came over his face on that bed was like none he’d ever had when that face belonged to him. It had an impish, feminine deviltry to it that made Casey shiver with pure fear.
“You know brother,” Kelly said with his voice, “I never knew you were so well equiped. It’s no wonder all the girls on the cheerleading squad chase after your tight buns.”
“Kelly!”
“Hey, what are you complaining about?” She/he retorted. “You didn’t end up with such a bad body, did you?”
“That’s not the point, and you know it! What if we don’t change back?”
“Then Sunday night we take the other formulas, right?”
“The only problem with that is, we don’t know if the formulas will work in reverse.”
“Um, could you stop jiggling so much Casey? You’re starting to give me a hard on.”
“Fuck you!” Casey spat back angrily. “This is serious sis!”
“Actually, I was thinking of fucking me,” Casey’s own voice said as his own eyes looked out from his sister’s mind at him, undressing him/her. And to make things even stranger, Casey could plainly see his old family jewels peeking up out of Kelly’s pink panty waist in responce to Casey’s near naked, hourglass figure.
“Get serious Kelly, I’m your own brother.”
“No, you are my sexy hot virgin sister!” Kelly said grabbing her over night penis. “And I’m just dying to see how this thing works.”
“You wouldn’t dare!”
“Then get the hell out of my way,” Kelly said getting up out of bed, and pushing past Casey on the way to the bathroom, and Casey’s bedroom, “cause if you won’t give me some pussy, maybe that hot assed girlfriend of yours, Jinny will.”
“Since when did you turn dyke?” Casey snarled as she passed by.
“Wanna come see a dyke piss standing up, sis?”

I seem to have created a Jykle and Hyde formula,
or more precisely the gender reversal has changed the roles
my sister and I usually take when in our own bodies. Her
macho attitude may also be due to the sudden influence of
massive testosterone levels in my former male body. I was
barely able to control those sexual urges myself when I was
the guy, so for her it must be a living torture. I hate to think
about her in my body screwing Jinny, but it might have a
positive effect that will allow me to talk her into telling me
where the rest of the fomula is, so that we can turn back to
our former selves. In the mean time, I find my own new flesh
quite a turn on too. Kelly always has been the most beautiful
girl around, but as I’m quickly finding out, she also has this
incredible itch between her legs that is driving me to the
brink of sexual insanity. Who’d have thought that a sweet
girl like her had all of these slutty thoughts crawling through
her beautiful, innocent head?

Casey put down the pen, closed his note book, and sat there in the dinning room looking at him/herself in the wall mirror.
“Shit!” He/she said to his/her image, “I can’t believe how fucking hot you look!”
Casey stood up then to get a better look, and his/her shaved legs almost gave out as he/she stared in awe at the erect nipples poking out of the white blouse. Casey’d had no intention of putting on one of Kelly’s bras, after all, that was her underwear, not his, but now Casey was beginning to reconsider that thought. He’d given in to putting on a pair of her silky white panties, just because they fit better than his boxer shorts had, but he’d put off wearing her bra for the awareness it would have given him of his/her new breasts. But there was no doubt that Casey needed something to cover up those erect nips now. Turning, Casey went to retrieve the undergarment, and in the process, passed every mirror in the house with each image making that secret itch more persistent with every bounce and jiggle. Casey didn’t stop until he/she was in Kelly’s bedroom, and standing before the full length mirror.
“No wonder Kelly is always primping in front of the mirrors,” Casey said with Kelly’s voice, “with a body like this! Why I could have any male within fifty miles crawling in my wake.”
Staring at the mirror image, Casey watched Kelly’s hands begin to take on a life all their own. Each finger snaking gently over smooth silky ripe teenage flesh. His sister’s flesh to be sure, but his now to do with as he wished. The forbidden hint of incest in what he was doing with her body while living in it, was simply too tempting to not take advantage of.
“Well, it is my body now, after all,” Casey told the mirror, finger tips brushing up against the swollen right breast as his other hand slid down under the waist band of those silky white panties that had been teasing this flesh since putting them on, “I should at least get use to what this body is capable of.”
It was then that Casey’s thighs closed suddenly as finger tips grazed against his sister’s clitty, and into her moist slit. Electric energy surged through his sister’s body, weakening those silky shaven knees, spreading outward those lushious smooth thighs sporadicly in supplication.
“Oh fuck!” Kelly’s voice shook with lust, “This is too hot for words! Maybe being a girl isn’t so bad after all. Let’s see just how slutty I can make you look sis.”
It took some time. Casey had never shaved his legs, let alone his underarms, or pubic thatch before now, let alone a woman’s. The bubble bath helped settle Casey’s nerves somewhat, but not much, and the applying of makup, and powder, and painting of nails fanned the flame once again.
It was just as Casey had finished getting into the black satin garterbelt, half cup bra, black seamed stockings that Casey heard the scratching at the door. It had to be Bear, which meant that Kelly had dropped him off before meeting Casey’s girlfriend to take her to the mall. Casey slipped into a pair of Kelly’s black pattent leather spiked high heels, and took several tentative steps to get use to walking in them. It was strange how if Casey walked with a little swiveling of the hips that it was relatively easy to navigate in the wierd footwear, and Casey had to admit, he’d never seen Kelly look so slutty in his life.
The scratching became more persistent as the smell of hot pussy tainted the bedroom air. To think that that odor came from Casey was a startling revelation. Still, the scratching pesisted, and Casey decided to let Bear in. He was probably just lonesome after spending the night alone at the vet’s, and missed his old pal Kelly.
“Welcome home, Bear,” Kelly’s voice cooed, as Casey squated down to welcome the sleek black and brown German Shepherd into Kelly’s bedroom, managing to close the door in the process.
Bear came right in between Kelly’s open thighs, and stuck his tongue out. The only thing was, that tongue swipped across Kelly’s left nipple, exposed by the scanty bra, and an electrical charge zoomed through Casey right to Kelly’s already steaming pussy.
“Hey there! Just what do you think you’re doing, boy?” Casey giggled with his sister’s voice, but stopped the moment Bear’s tongue licked up the split between Kelly’s/his legs. “Oh shit, don’t tell me you and her……ooooooooooohhh wow! That feels incredible.”
Casey stayed in a squat then as the family pet lapped at what he thought was Kelly’s pussy, but in reality now belonged to Casey. The young teen’s thighs parting even now to give the animal’s tongue better access to those strange new itching folds between Casey’s legs. Casey’s new breasts also responding as the nipples hardened growing to three quarters of an inch in length, and tingling with electric shocks every time the dog’s tongue swiped up along the split in Casey’s nearly denuded crotch.
Now Casey was no queer, not by anyones standards, but now with his chromasomes changed to those of a female, his sister’s genes in fact, Casey was for all intentional purposes a girl himself now, and the body that formerly belonged to his sister was reacting to the dominant male presence of the family pet. Just as any female might react to the same stimuli, Casey too began to react. Only more so because he hadn’t grown into this body the way his sister had, and hadn’t been there when their mother preached to her at every stage of developement along the growth cycle about the way a proper girl should act on all occations.
Not being hindered by parental morals, as his sister had, Casey just went with his new found feelings, and to hell with society, Casey wanted some sex, and if letting Bear fuck Casey was the culmination of this little reunion, then so be it. After all, dogs didn’t talk, nor could they get a girl pregnant. Besides, Casey was just itching to see what his sister looked like when she was getting fucked like some cheap back alley street whore, and they were alone in the house which meant Kelly was out trying to get a piece of ass from Casey’s girl friend Jinny. All things being equal, Casey decided right then to set up his dad’s video camera, and put on one hell of a show with Bear that he could use later when Kelly and him switched back to themselves for a little personal late night pleasure on his VCR, or maybe even a little blackmail if it became nessasary.
“Hold that thought, boy,” Casey said, standing up on wobbly legs, and heading for the video camera. Bear following right behind with his tongue lapping happily at Kelly’s/his tight heart shaped ass. It only took five minutes to bring everything into Kelly’s bedroom and set up the camera with a fresh new tape, turn it on to record, and then climb into Kelly’s bed.
“Here boy!” Kelly/Casey patted the mattress beside him.
Bear at first puzzled by this, as he wasn’t allowed on any of the furniture in the house, soon jumped up to join his mistress, quickly moving inbetween nylon clad legs, his tongue out as soon as he reached naked flesh at midthigh then trailing spit up towards the thrill scented wet slit waiting openly for his attention.
Not sure if he was acting, or not, Casey let out a low gutteral feminine moan, then just followed Bear’s lead from that point on. Bending legs upward while at the same time splaying them outward at the knees as Bear’s tongue at long last made contact once again with that moist slit between Casey’s thighs framed in black garterbelt and seamed nylon stockings. Casey had already been cupping and fondling his/her tits, squeezing them, and pinching the nipples, but when Bear’s tongue found it’s way to that new pussy, and laved at the clitty Casey lost all control of his female flesh. Casey’s hands went right to Bears head to hold him in place and even wrapped those long elegant leg’s of his sister’s around the dog’s back to keep him in place.
“Ooooooooooooooh yesssssssssssssssss, baby!” Casey squeeled. “Eat my pussy boy! Lick my twat you dirty fucking dog! Oooooooooooooooooooooo fuck! That’s soooooooo good! You can have Kelly’s pussy anytime you want baby! Ooooooooooh yeah! Oooooooh fuck yeah!”
Casey/Kelly’s ass began to hunch up at Bear’s face, much like Jinny’s hips bounced when Casey ate her cunt out, and now he realized that Jinny just couldn’t help herself, it was an instinctual reaction to a girl when a soft wet tongue was applied with skill to her sensitive vagina. The building up of some perverse pressure inside that made Casey want more, and still more, and then suddenly. It happened.
“Oh! Oh shit! Oh Fuck! What’s happening?!!!!!! I’m…….cummmmmminggggggggg! I’m cuuuuuuuummmmmmmmmmminnnnnnngggggggggggg!”
To Casey it was like falling over Niagra Falls only without a barrel as every nerve ending suddenly ran from DC current to AC, and then back and forth again and again. Reality took on a whole new dimension as colors swirled, and images flashed and faded. That itch between his legs getting the best cunt scratcher of all times sent Casey plumeting down the wet water falls into a pool of rippling sunsets panting as if he’d just made a hundred yard rush to make the game winning touchdown all by himself.
In his/her dazed state, with Bear still lapping at the Y, Casey came to the realization that women had cuming all over men just by virture of the length of time they climaxed, and how quickly they were ready for the next assault on their ripe flesh as that dog tongue brought Casey to yet another orgasm right after the first one, and then another, and another. Until, completely out of control, Casey rolled over, and fell off of Kelly’s bed altogether ending up face down, and sprauled out with limbs all ackimbo, with Bear panting and licking at Casey’s exposed ass. Casey had no strength left to shoo the dog away, deciding in the end to let the dog have his way. After all, Bear had earned that much, at least.
It wasn’t until Casey tried getting up on his/her hands and knees five minutes later that a new problem arose.

************

 

“Say Jinny,” Casey asked her, “have you ever wondered what Victoria’s Secret really is?”
“You always ask me that when ever we pass this window,” she replied, then on an impulse Jinny turned into the fashion store to see if Casey would follow her this time, and sure enough her boyfriend did. Stranger and stranger, Jinny thought, he never followed me in here before. I wonder what’s gotten into Casey today? He’s so, well, er, sensitive.
“Hey now, look at these,” Casey said holding up a pair of sheer black nylon bikini style panties, “I’ll bet you’d look wild in these!”
“At thirty dollars a pair, you don’t expect me to buy those, do you?”
“Nope,” He replied, and then took the hanger over to the counter, and did the strangest thing he’d done all day. He bought the panties himself, and handed them to her saying, “now go put them on, so I can peel them off of your fine self later.”
Without giving it another thought, and blinking back her own surprise, Jinny headed for the changing room to put on her new finery. She still wasn’t sure what had happened to change Casey so much, but she wasn’t about to complain at this sudden manly attitude that was so endearing to her, and to a few of the other women looking their way either. Any man who could pull off buying his girl a pair of panties without blushing, stammering or looking queer was a plus in any woman’s eyes, and in no time Jinny’s new panties were as wet in the crotch as the ones she’d taken off to replace them.

************

 

Unable to think clearly, Casey, after rolling off of the bed boobs side down had finally caught his/her breath enough to rise up on hands and knees, just barely getting the upper part of Kelly’s body back on her bed before Bear jumped up and landed on her back with all of his weight in the obvious dog fucking position. Bear’s front legs wrapped firmly around Kelly’s slim waist overwhelming Casey’s new feminine body by the dog’s sheer mass and strength.
For the first time in Casey’s life he/she knew what fear was really like as the dog’s pointy barbed prick poked at Kelly’s privates looking for a place to bury his bone, and scratching Kelly’s sides with his dew claws in the dog’s excitement to copulate with her.
“No Bear! Down boy! Get off of me! You’re hurting me, boy!”
But the Black German Shepherd didn’t understand, and Kelly’s flesh was no match for the dog who outweighed her by at least 25 lbs. Casey’s only recourse was to reach back and grab hold of the dog’s front paws to keep the dog from making any permanent marks, and Casey barely was able to do that before the barbed tip of the German Shepherd’s canine cock got lucky and sliced right inbetween Kelly’s delicate pussy lips. Bear suddenly froze in place, then readjusted his hind legs a bit, holding the first inch of his cock inside of Kelly’s body as he did.
“Oh Shit! I’m fucked now!” Casey gasped with Kelly’s voice as the dog’s cock charged right up his sister’s virgin pussy slicing right through the hymen Casey hadn’t known he’d aquired, and now suddenly lost with a great deal of pain as Kelly’s tight pussy was broken open for the very first time, and by the cock of a dog no less. “Ouch! Ouch! Ooooooowwwwwwshitttttt! Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!!”
Blood rushed to Casey’s face, chest, and more importantly to Kelly’s speared open gash below, and Casey could feel the sticky wetness lubricating her stretched out cunt for the hairy beast on her back. The pain, while incredibly intense at first, soon became a throbbing dull ach, much like when he was in his own body, and his dick was as hard as a rock looking for some attention. Bear at least had stopped the moment his dick was buried in Kelly which allowed Casey time to get used to this new fully jam packed feeling of having a pussy stuffed and stretched full of cock.
Not that bad really, Casey thought, once you got past the pain of the first moment. Hell, it was better than that even, as Casey felt the sparks once again running through Kelly’s nipples to her pussy and back again. Oh yes, this would be even better than Bear’s tongue!
“Do it boy!” Kelly’s voice cried out, looking straight over at the video camera. “Fuck me! Fuck me like a bitch Bear! Fuck me, I’m your bitch nowwwwwwwwwwwwwww!”
Encouraged by the tone of wanton lust dripping from his mistresses voice the dog started a smooth easy thrusting, pumping action pulling with his front paws as he humped forward with his hind legs making his back bow up and his tail curl at the same time. In moments Bear was pounding his cock into Kelly’s pussy, his hairy belly slapping up against her hairless ass in the age old beat of uncontroled fornication. It was during this point that the knot that grows in every canine prick to lock the male to the bitch began to swell inside of Kelly’s fuck hole. Not that Casey was unaware of what was taking place in Kelly’s body, but the feeling wasn’t unlike having a large bowel constiction you wanted to pass before it got much bigger, and he had no control over it anyway. Still, it made those little electric shocks running through Kelly’s body more intense, and Casey could tell that this was going to be one hell of an orgasm the way it was taking shape.
Girls may have better orgasms, Casey thought, but they sure paid a higher price to have them. And no way do I want to find out about the pain of having babies if just a cock hurts this much down there! If I ever get back to being a guy, I swear I’ll treat women better! They deserve better, that’s for sure.
The thought going through Casey’s mind took less time than one bluring thrust of the dog’s penis into Kelly’s pussy, and that didn’t even include the pulling out time. This of course gave Casey more time to think about the dog fucking that pussy down there as Casey hung on to the edge of Kelly’s bed by her boobs alone as their bodies jerked to the old in and out rutting slap happier, orgasm chase. And suddenly Casey’s female flesh crashed into the next level of climax.
“Oooooooooooooo yesssssssssssss ssssssooooooooo fucking goooooooooooooood! Fuck me! Fuck me! Fuck Meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!”
Casey wasn’t sure how it was happening, but could feel Kelly’s cunt muscles clasping and unclasping around the ever pumping drill bit mangling her insides to mush. Her clitty exploding right along with some unknown inner sensor in that pulsing new snatch that drove Casey to the pinnical of insanity’s wedgy, and suddenly Casey felt scalding hot liquid lancing against that newly aquired cunt lining, sending Casey sky rocketing to entry level burn out, as if Kelly/Casey had been struck by a bolt of heat lightening.
“He’s cuming! He’s cuming in my cuuuuuuuuuuuuunnnnnnnnntttttttttttttttttt!” Casey squeeled with Kelly’s voice, and just as suddenly passed out from the over load of sensations.

************

 

“Why are we going to your house Casey?” Jinny asked as the car pulled into Casey’s driveway.
“My mom and dad are out for the weekend,” Casey’s voice replied, “and I thought it would be a nice change to do it in a bed for once. Besides, I can’t wait to eat that pussy of yours through those new see through panties I bought for you.”
“But what about Kelly?”
“Let her buy her own panties,” Casey chuckled getting out of the car.
“No. I mean, what if she’s still home?”
“Then she can find her own entertainment, right,” Casey said, helping her out of his car.
“Right,” Jinny giggled, a wicked grin forming on her face to match the one stapled to Casey’s, “just don’t expect me to be the entertainment commitee. I told you before, I’m not into girls, and yes, before you ask me again, that includes your beautiful sister Kelly, too.”

************

 

Casey/Kelly woke up slumped on the floor chest down and ass up in the air looking through a blue haze just as Bear pulled out and dismounted splashing his joy juice all over the back of Kelly’s thighs as well as spilling out onto the carpet to form a puddle as dog goop leaked out of her cunt to the floor below. Raising up a bit Casey/Kelly’s vision cleared up tremendously, and a look down at the carpet showed where the blue haze had come from. One of Casey’s experimental bottles, in fact the one needed to turn Casey/Kelly back into plain old Casey/Casey. The pink bottle was just poking out between the matress and springs now that the matress was slightly off kilter.
“You little minx,” Casey chuckled to himself, getting up to shut off the video camera, “so that’s where you hid them, eh. Well I hope you enjoy this weekend sis, because tomorrow we are changing right back to the way we were.”
A quick look over at where Bear was licking his own cock clean reminded Casey that he needed to go clean up too, before Kelly/Casey brought Jinny home to fuck. It didn’t take much imagination to figure out that Kelly was going to do everything in her power to stay in Casey’s body long enough to get a piece of Jinny, even flaunt it in front of the real Casey if she could.
“I’ll bet she had Bear planned all along too, and hoped to catch us in the act with my girlfriend as a witness, no doubt,” then looking at Bear, “I hope you enjoyed that boy, and don’t you forget, there’s plenty more virgin pussy for you once Kelly turns back into herself.”

************

 

Kelly/Casey opened the front door to let Jinny inside as quietly as possible. By now her brother was sure to be tied into knots by Old Bear and that wild tongue of his, Kelly thought.
“Hi!” Twinkled Kelly’s own voice as she and Jinny entered the living room, startling the real Kelly hidden inside of Casey’s flesh. “You two have a good time at the Mall?”
“Um, er, yes. Yes we did,” Jinny answered nervously for them both as Kelly/Casey starred in disbelief at her living reflection sitting on the couch in a pink halter top, and white cut off shorts watching television with Bear laying at her feet on the floor.
“Yeah? That’s nice,” Kelly/Casey replied, “maybe next time I can go with you two.”
“Well, um, maybe, sure sis, but um, me and Jinny have to go over a homework assignment now.”
“That’s okay, I understand. I’ll be in here with Bear, if you need anything give a yell.”
The only thing Kelly/Casey needed was to get Jinny into Casey’s bed and striped for action, her new penis had a mind all its own, and had been poking out against Casey’s 501′s all day long. Kelly only hoped now that the real Casey wouldn’t get in the way of her finding out what fucking was all about from the male’s view point now that Kelly’s plan to catch Casey with the dog and have a fourway orgy had gone awry. With a quick disapproving look down at Bear Kelly/Casey guided Jinny up the stairs to Casey’s room, and once safely tucked away out of sight closed and locked the bedroom door, and kept it locked for the next three hours straight.

“CAAAAAAAASSSSSSSSSEEEEEEEEEEYYYYYYYYYY!” Kelly screamed bloody murder with her own voice once again as she woke up in her brother’s bed in his underwear, but her own body.
The knock at the door before it opened was a mere social politeness as Casey stood there in his own clothes, in his own body once again, looking down at his sister whose face, and chest was beet red, and whose nipples poked out of one of Casey’s old T-shirts like bottle caps, and whose pussy showed through the open pee hole of a pair of his boxer shorts.
“You know, a week ago, I’d have given real money to get a look at you like this sis, but after yesterday, I’ve seen and felt everything you have.”
“You bastard!” Kelly fumed. “How’d you do it? How’d you change us back?”
“The formula wore off,” Casey lied shrugging his broad shoulders, believing it best that she didn’t know that he’d drugged the desert last night after Jinny went home. The bottles once again tucked back under Kelly’s mattress, only now there were just colored harmless vegetable oils in those bottles. She wouldn’t be pulling any more surpises like that on him again unless he wanted her to.
“Oh,” Kelly sighed, her hopes for the weekend dashed now, “I guess you’re still pissed at me for fucking Jinny, eh.”
“Not at all,” Casey replied coming in to sit on the edge of his own bed next to Kelly, “in fact, I was just curious to, you know, know how it felt to you to at last bust your cherry, so to speak?”
“Don’t ever lose that girl Casey,” Kelly said with a smile, “if anything, let her be the one to dump you.”
“That good, eh?”
“Well, I’ll tell you one thing,” Kelly spoke, her voice becoming wistful, “she isn’t the whore I thought she was, but she’s one hell of a slut for the right man. If you know what I mean.”
“I do indeed,” Casey said, and pulled his sister to him for a brotherly hug. The kind he used to give her when they were just kids, “and I’ve learned a few things about you girls too.”
“Oh?”
“It ain’t easy being you, but it’s a hell of a lot more rewarding.”
“Funny, but I was going to say the same thing about you, Casey.”
“Yeah? Well, you girls look better no matter what you wear, or don’t wear for that matter.”
“Hmmmmmm, you might have a point there,” and she looked down at the point forming in her brother’s 501′s at that very moment.
