"Thanks for helping me clean out all this old junk Jess" Linda Holbrook said with a smile to her granddaughter Jessica.
"Oh it’s not a problem at all. I'm glad I can help" Jessica replied.
"I just want to get rid of a lot of this because no one will want it or need it. I might as well do it now while I can help and sort. There's trash, there's stuff for Goodwill, but there's also some other cool stuff you or your cousins might want" Linda said.
"I'm calling dibs on the record albums" Jess said. "My old hippie Grandma has to have some cool stuff around"
"I can’t believe vinyl is back. I rebought all my favorites on CDs and now you signed me up with that Spotify. I envy you these days. If you want to try out a band, it's all there at your fingertips. You don't have to try to find someone who owns an album or buy it and find out you only liked the one song on the radio" she laughed. 
"Guess I was just born at the right time huh" Jessica said with a shrug and a smile.
She brought down another box to sort through and set it on the card table they had set up in the attic. Piles sat around them as they sorted through.
"Oh! One of your Granpa's old Army shirts" Linda said bringing out the Olive green shirt.
"That’s mine!" Jess laughed taking it from her Grandma's hands. "That is so cool! Would he have worn this in Vietnam?"
"This would have been one of his shirts from base. When he was at Fort Hood. They burned his combat shirts...washing them in the rivers over there turned them red he told me" Linda explained. "Keep it! He would be happy with you having it. He loved you dearly"
"I loved him too...I miss him every day" Jess said. 
"Me too honey" Linda added with a hug. 
Jess put it on but immediately got hot in the stuffy attic so she took it off and put it by the door on what was shaping up to be her pile.
The rest of that box went to Goodwill.
"Ooff...this is heavy" Jess said really putting effort into lifting the next box. It made an audible thud on the table.
Jessica Holbrook was 25 and worked as a graphic artist. In her spare time, she wrote and illustrated her own comic book. It was getting a good following on reddit and discord and a few other independent online venues. Her dream was that it would catch the attention someone who could publish it mainstream. 
Working in a hot attic, Jess was dressed in just a white tank top and denim shorts. She stood just 5'3" and the first thing everyone noticed was her long naturally curly brown hair that today she had pulled back in a ponytail. She could not control or tame the frizz in the humidity. She had bright green eyes and a wide, easy smile.
Moving around and lifting, she kept having to pick her shorts out of her ass and adjust her bra and tank. She wasn't fat; she was curvy and stacked up top though with a flat stomach accentuated by a naval piercing.
Her grandma had been more accepting of that and her piercing in her nose than her mother had been.
Linda sighed and pushed aside a few errant hairs that tickled her face. She was 72 and had allowed her hair to go full natural gray. Her hair was collar length with some body and a little longer in the front. Her eyes were a clear, pale blue, her skin was soft and lined but not nearly as much as most of her friends.
She had softened with age but she walked 2 to 3 miles everyday to keep in shape and her Doctor said she was in great health for her age. Today she wore a plain light blue top and khaki shorts along with ankle socks and some plain white canvas slip on shoes. 
She had told Jess to wear shoes up here but she hadn't listened and was barefoot. She swore that girl was always barefoot.
"Is Grandpa's bowling ball in this box, shesh!" Jessica said swiping frizzy baby hairs off her temples with the backs of her hands.
"This must be his stuff. I don't recognize most of it. He got some boxes from his brother John...this must be one of them"
"I never met Uncle John" Jess said.
"He was killed in a car accident a few years before you were born. He lived in California. I only saw him a handful of times myself" Linda said. "You want to talk about an old Hippie haha. He got way into the San Francisco late 60s scene. Drugs...your Grandpa and he were not close" Linda said as she pulled out a bong.
"Right on cue Grandma!" Jessica roared with laughter "Oh I love it!"
Linda blushed and waved her hand dismissively as she pulled out a dusty old statue. "More hippie decorations. Looks like a love statue" she wiped a dust rag over the carved black wood figures of two people embracing. "Looks like…" Linda squinted "Do they have jewels for eyes?"
Jessica came over to see. She leaned in "Sure looks like it" she said as her hand came up. Most of her hand wrapped around the statue but her pinky finger overlaid her Grandma's pinky.
As both of them held it, the statue moved.
"AH!" Linda yelled and jerked back.
"Oh my God!" Jessica yelled as they dropped the statue.
It crashed on the ground between their feet breaking in two pieces. One of the bodies rolled over towards Jess while the other spun and stopped in front of Linda on top of the tip of her shoe.
Jessica stuck out her right foot and tapped at it with her big toe. "AH!" She screamed and jumped as the eyes began to glow.
Jessica wanted to run but before she could, a blue light shot out from the eyes engulfing her. She looked over and saw her Grandma frozen and engulfed in a red light.
Then, it stopped. The light vanished.
Linda stood with her jaw agape.
"I am out of here!" Jessica announced. She reached over and grabbed Linda's shoulder.
As she did, the lights reversed and flashed again but this time Jessica was in red and Linda was in blue.
"I think you’re right honey. I have no idea what the heck is going on" the lights stopped again leaving just the overheads.
"Break time!" Jess said leaving in a hurry and running down the stairs. 
She didn't stop. She heard her Grandma coming down too so she kept going. Past the floor with the bedrooms and back down to the ground floor.
Jessica was shaking a bit but laughing as Linda came down. "What the heck was that Grandma?! That was weird!"
"Damn old hippie!" Linda muttered "scare me to death…"
"My heart is beating out of my chest!" Jess said dramatically.
"Give me a heart attack…" Linda said heading to the kitchen. She filled glass with water from the sink and drank it all.
When she went back to the living room where she had left her granddaughter, Jess was staring out the front window.
"Are you alright honey?" Linda asked.
"Just tired all of a sudden" Jessica replied.
Linda honestly felt the opposite. She was on an adrenaline high after the light show. "Have a seat...can I get you something to drink?"
Jessica turned to her grandma "No I'm not…" she trailed off furrowing her brow and squinting looking back.
Jessica's heart started to beat faster. She leaned forward, closer.
"What? What is it? What are you looking at?" Linda said now getting a feeling of queasy uneasiness filling her.
Jessica slowly reached over and <pluck>
"Ow!" Linda said as Jessica plucked a hair from her head.
Jessica held it between her thumb and forefinger; studying it, examining it.
Linda finally saw it and now she stared too. 
The hair was long, brown and very curly. 
"That came from me?!" She asked incredulously.
"Yeah Grandma. I just saw it poking out; way out of place and I…" Jessica stopped talking. Her eyes went wide, she dropped the hair and slapped her hand across her mouth.
Where she had plucked that single hair, now dozens just like it had taken its place. "Grandma! Mirror! Now!" She yelled and grabbed Linda by the arm dragging her down the hall to her bedroom. 
Linda's master bedroom was on the bottom floor but the three rooms her kids had grown up in were upstairs.
"AH!" Linda said upon seeing herself. Her hands went to her hair and she grabbed and pulled at it, tugging it and running her fingers around.
Both of them stared at it. Linda's hair was going crazy. Growing out fast and long and wild. It was turning a dark, rich brown color. Every strand of her gray hair was being replaced, transformed. Her hair was snaking out at an impossible rate of growth, doubling in length, going over her collar to over her shoulders and upper back. Wild baby hairs sprouted at her temples. Her longer in front swept to the side style was vanishing.
A cold feeling hit the pit of her stomach.
"Grandma!" Jessica yelled "Why is your hair turning into mine?! It looks just like mine does!"
"I don't know! I don't understand what's going on at all!" Linda ran her hands down over her cheeks, pressing down.
"I don't...I  can’t feel my face. I'm going numb" Jessica said recognizing her hair on her Grandma's head. She looked in the mirror and looked the same but their hair was quickly becoming a match. 
Another two inches in length grew out. Linda stared at her reflection in the mirror in shock. She fluffed out the ends of her now long curly brown hair on the left side with her left hand. Her hair now stopped at the top of her breasts.
Jess walked up slowly next to her, joining her in the mirror. Numerous she undid her hair tie and let her ponytail out. Her hair fell and she fluffed it out; their hair was exactly the same.
"This is some freaky ass shit" Jessica said. "I am so confused right now!"
"You and me both! How? Why?" Linda said.
"I don't have any idea except that freaky ass statue and the glowing lights!" Jessica replied pointing towards the stairs.
"But why my hair?" Linda asked.
Jessica did an exaggerated shrug gyrating her shoulders and hips, her big boobs shaking in her tank top, her lips pursed, her eyes wide.
Linda started to laugh. She couldn't help herself 
"What are you laughing at?" Jessica asked.
"It's either I laugh or I cry...I look absurd!" Linda said shaking her head.
Meanwhile, Jessica's hair now started to creep upward. Slowly at the very beginning. Then, a single strand of her luxurious hair turned gray. It shot straight out the back and pulled up to collar length.
Another hair joined it.
Then another.
A dozen more turned gray and pulled up.
Jessica felt a slight tugging at the back of her neck and the top of her head. She reached up and scratched as Linda wound down her hysterical laughter.
Jessica's blood ran cold and her numbness spread to her entire body. She froze in place, her eyes widened as big as they could go. She let out whatever air was left in her lungs and stared.
Hair by hair, her hair was turning gray. Not just gray though, the texture was changing from curly to straight and incredibly, the length was as well. Like it was being cut and styled by invisible hands and forces it was getting shorter.
Jessica's hair now rose up to collar length. Some body puffed into it and the front swept forward and off to the side.
"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!"
Linda slammed her hands over her ears at the scream. She flinched and turned away but then turned toward her screaming Granddaughter. Then she screamed too.
They grabbed each other and after a minute of incomprehensible mumbling, squealing, yelling "ohmygodwhatamigoingtodo!"
Jessica was hyperventilating, Linda was crying and blubbering "ohmygodwhatshappening"
"Whyisthishappeningtous"
Linda shook away and put her hands to her temples and pressed down. Jessica turned back to the mirror. She looked like herself but somehow she now had her Grandma's hair. Her Grandma now had her hair.
They looked at each other in silence, both just breathing but thinking the impossible.
"Give me one more sign...just one more" Jessica thought "One more thing changes and I'll know what I'm thinking, no matters how impossible it sounds, is actually what's happening to us"
Jessica ran her tongue over the back of her upper front teeth. Something felt different. Like, a little bit sharper. A little different edge and angle. Holding perfectly still now and holding her breath. She felt it. A tooth moved.
Jessica lurched toward the dresser and leaned as far forward as she could pressing down with her hands until.her little feet lifted off the ground.
She quickly bared her teeth pulling her lips back. 
Seeing slightly crooked, slightly larger, slightly yellowed teeth shocked her but also confirmed it to her. 
Jessica eased back. Linda anticipated what she had discovered and what she was going to say. Jess turned to her "Grandma. I've got your teeth"
Linda nearly fainted.
She staggered to the bed and sat down hard "what is happening to us?"
"We're changing places Grandma! Switching bodies! Freaky Friday shit but for real and it's piece by piece! No just waking up in each other's body...we’re physically exchanging our traits and parts"
"But I can’t!" Linda yelled.
"It's too late for that! We are and we will! You already look like you have less wrinkles and lines and I can see your teeth are straighter and whiter too!" Jessica informed her.
As Jess looked, Linda's lips filled out, plumping up and became smoother.
She grabbed Linda by the hand and hauled her up, dragging her to the mirror. They stood side by side.
"We'll figure this out and we'll change back. But for right now, we can't do a darned thing but let it happen obviously. We can't stop like this. We switch places and then we work on switching back" Jessica said.
"But you'll be old! I can’t take your body!" Linda protested.
"You’re just borrowing it is how I'm looking at it" Jessica said slurring the last word as her tongue reshaped itself inside her still shifting mouth. Her lips thinned and puckered. Thin lines etched in along the corners digging deeper as her skin began to soften and sag a bit.
Jessica's cheeks softened and drooped. More lines came in around her chin which began to inch back, pulling in taking her lower jaw with it as her skin continued loosening. Excess skin began to slip and fold along her neck.
"Oh crap" she said as she began to take our her nose ring. Then, all her ear piercings: She had 5 in her left ear and 4 in her right.
Linda watched her skin smooth out. Her lines around her mouth and chin filled in with supple skin. Around her eyes and across her forehead, those lines also began to retreat.
"How can you be so accepting of this? This is impossible!" Linda said as her chin shifted forward.
"Obviously it's not impossible Grandma, it's happening to us as we speak" Jess replied still working her fingers on her ears. "And trust me! I AM freaking out"
"Mmmpfh" Linda said as her tongue grew and her mouth shifted. She put her hand up to her mouth. She felt her lips shift and the spot underneath her nose moved causing her to jerk her hand away.
Once she did she saw a stronger jaw and chin and no excess skin on her neck flapping around.
Linda's cheeks lifted up higher, the skin pulling taut and exposing strong cheekbones.
Jessica's cheeks now settled in. She was really seeing her Grandma appear before her eyes. Her eyes...her eyes were changing cor.
The green was draining out leaving them a pale blue.
She blinked as her eyelashes thinned and more lines formed. Her eyes narrowed and shifted, sinking deeper. 
With all of her piercings in her cupped hand, she put them on the dresser and let go "Aaaand I've got your eyes now too"
Linda shot a sideways glance and took off her glasses and handed them over.
"Yep. I'm going to need those more than you now Grandma" Jessica said. "Mine are at home. I only wear them when I'm drawing"
With that though Jess looked at her hand. She flexed it. "Wonder if you're going to get my skill too?"
"Well if we're like this for longer than a day, I sure as he'll hope so or else you'll be fired!"
"Grandma, I'm already freaked out enough. You don't have to bring that up okay"
Linda's vision began to clear. She saw Jessica sliding her glasses on.  The image in the mirror sharpened. She saw her eyes were green. They came forward more prominently; larger and wider; definitely Jessica's eyes. Her eyelashes thickened, her eyebrows now joined in growing darker and bolder on her smooth forehead. 
A youthful face was in front of Linda. "I look so young!" She thought despite her reservations.
Her nose remained, but not for long as it began to shrink down smaller. Jessica's nose was tiny and pert; Linda's was longer and larger.
They switched noses.
As Jessica's elongated, Linda's shrank. Jessica's upturn at the end straightened out of for Linda's to turn up. Their nostrils both flared simultaneously as their bridges swapped places.
Finally, the hole in Jessica's right nostril closed and one opened in Linda's. 
Linda swept her hair back as she felt a pinch in her ear. 4 new holes joined the one she had in her left ear and 3 more joined the right one.
Jessica could only smirk. By the time she moved her gray hair she saw longer ears, each with just a single piercing in each.
Jess stepped back as did Linda and they turned toward each other. It was their body but with the other's head on it.
Linda inadvertently looked down at Jessica's large chest "Oh my" crossed her mind.
"Who knew that not only would you get your attic cleaned out, you'd get my body too. Guess you can clean it yourself now" Jessica said.
"Now is not the time for jokes…" Linda started to say.
"You said it yourself, you're either going to laugh about this or cry about it and I'm…<cough, cough>"
Jessica held up one finger as a tickle ran through her throat. "Excuse me" she said and stopped dead in her tracks.
Linda's big, expressive green eyes shot wide open and she smiled a wide smile upon hearing the no longer high and nasally voice of her granddaughter but instead the much lower and smoother tone of her own voice.
Linda pointed at her "You've got my!" She laughed a very different sounding laugh to her own ears. It was high and faster. "Oh my God! I've got your voice now too!" Linda said sounding exactly like Jessica. She even talked faster like Jess did.
"Yes, it's apparently switched our voices too" Jessica said in a slower and calmer tone.
"Haha...this is so freaky!" Linda said and Jessica threw her a curious look. "Maybe this is all part of it but sounding like me and speaking like me are two entirely different aspects of personality. I'll bet you had never used the word freaky before just now"
Linda stopped "I say it all the...Ope!" She slapped her hand over her mouth in shock. "You're right and not only that...I almost answered that like you would have! I think our thinking is swapping too!"
Jessica nodded. "I can definitely tell I'm thinking differently, less impulsive, more deliberately"
"And I am all over the map here" she laughed Jessica's laugh again. "Hot mess Jess coming up!"
"You couldn't stop it even if you tried. You've taken on my personality and I'm getting yours. This is fascinating. I know who I am and all but it's like we're both each other. Both of us reside in each other. We'll have each other's body but both of our minds"
"Trippy. All I can say is trippy. I can feel my old self but yours is so strong. Dominant"
"And yours is now the dominant one for me too. I can’t talk like I was. I'm trying and I simply can't but I know it's there. That's a good thing I think. It means we can fool everyone and yes, you will get my skills but we'll also never forget our original selves" Jessica said.
With that though there attention was brought back to their bodies. Jessica felt her shoulders roll forward and a tickle worked up her back. Her spine elongated and she grew 3 inches. "Oh. Well that's different"
Linda snorted laughter "you finally got your growth spurt Munchkin!"
"You haven't called me Munchkin in 15 years" Jessica replied.
"So you were what? 57 by my math haha" Linda laughed. 
"We haven’t swapped everything yet" Jess reminded her.
"But you're the one already acting like an old lady. Saying 'well that's different' to a 3 inch growth spurt up your spine. C'mon girl!" Linda said.
"Oh please" Jess waved her hand dismissively. "Once you've dropped to my height you'll wear those strappy high heels and those thick wedges you like so much to get 3 or 4 inches back"
"Well you know me I guess...I have to at least try to get as tall as my sister...who gave her the height gene, I mean, c'mon!" Linda laughed enjoying their teasing.
"Oh our personalities are definitely taking hold" Jessica confirmed. 
"It's kind of spooky how easily I can slip into acting like you already. I still have my own body. But yet I can still draw on a lifetime as me too" Linda said.
Linda shivered all over as a chill ran down her spine compressing it as it went. Linda shrank 3 inches down to 5'3" "Uh...I'm short!" She shivered again.
"Unfortunately you're going to get used to looking up at people as long as you're me. Shortest one in the family"
"That's why I nicknamed you Munchkin" Linda replied "I could just tell you were never going to catch up"
"Yeah well...we still played volleyball and basketball at that height" Jessica replied.
"And we kicked butt haha" Linda replied.
After a brief lull the changes picked up again as Linda's shoulders pulled back straightening her up more.
Underneath her loose light blue top, Linda's arms began to firm up. The skin pulled slowly tighter and tighter. Muscles perked up and reformed stronger than ever. Her jaw dropped in surprise and she brought her left arm up like a bodybuilder doing a bicep flex. She wrapped her hand easily around her upper arm "Oh my gosh! Hahaha! I’m strong! No more floppy old lady arms when I wave" she blushed.
The skin and muscle continued to strengthen down bother forearms. She flipped her wrists as the pain there vanished. 
Wearing a tank top hadn't been a big deal when Jessica had gotten dressed that morning. She figured she'd get hot and sweaty and sticky; she never thought she'd get her Grandma's body. 
Her arms and shoulders were fully exposed as her skin began to age. It grew rougher and loose, spots appeared all over, the texture changed. In places it was leathery and in others, it was paper thin.
"Oh lord" she said as her upper arms started to change into her Grandma's. "Neck, arms and hands. The best way to determine someone's real age is to look there" she said. 
"Aw…you're going to get your bingo wings!" Linda said.
"Not funny" Jess replied as the skin of her upper arms drooped and sagged. Her muscle tone weakened and every slackened "Oh my gosh...it loks like I'm a bat or a flying squirrel with all this extra skin up here" she spread out her arms in a Vampire pose watching the stretch mark lined skin hang.
The changes continued down her now rougher forearms to her wrists where a stabbing pain suddenly jabbed in making her flinch.
Linda held her hands out flat, palms down and Jessica joined her putting own up just across from them, the tips almost touching.
Jessica's fingers and toes were painted white, Linda's were painted red.
Jess looked at how old her Grandma's hands looked. The prominent veins, the blue coloring, the bumps and nodules, the crooked fingers, the larger swollen knuckles, thin skin and thick nails.
Jess slipped off her rings. She wore 4 of them all with various Celtic symbols on them; the Celtic knot, the tree of life, the Celtic Dragon and the trinity spiral.
Linda wiggled her old fingers. She had to work to take off the old wedding band she wore but it came off with some effort. 
The skin on the backs of Linda's hands swelled up as natural moisture built up their suppleness. The skin toned stabilized, the bumps and nodules vanished as the veins receded to barely noticeable.
As Linda's hands regressed, Jessica's aged. The skin thinned as moisture drained. Bumps and nodules appeared, blue spots appeared as thick veins rose up prominently. Her fingers started to bend, going crooked while Linda's straightened out. 
Linda's knuckles shrank and smoothed as Jessica's popped and bulged. Linda's nails smoothed and thinned, merging with her fingers more fluidly. Her red nail polish lightened to bright pink, then light pink, and finally, it turned white. 
Jess felt her fingers stiffen. It took effort to move them, a dull ache settled in with sharper pains coming when she moved them in certain ways. As her fingers thinned, turning bony in appearance, her nails thickened and with less skin around them, they looked more prominent. Her white nails turned a light pink, progressed to bright pink, and finally bolder to red.
Jess flipped her hands over to look at her palms; thin and papery with very faint fingerprints.
With effort, she balled her hands into fists. But out of the top of her visual field, Jess saw white nails flashing and flipping, spraying out and wiggling fast and wildly.
"Oh. My. God. I can’t believe it! No pain! None! I can't remember the last time my hands felt this way!" Linda said balling them up, spreading them out, flipping them back and forth. Linda let out Jessica's loudest braying laugh as she rocked back.
"Well it sounds like someone is now appreciative of this circumstance"
"I'm not rubbing it in. I swear! I'm still just as freaked out and worried about this as I was before" Linda said.
Jess was looking over at her when she noticed the skin on Linda's chest smoothing out.
"Oh" Linda said going white. "OH!" She fanned herself with her hands "is it hot in here…?I feel hot all of a sudden" her cheeks flushed red. Her face turned to a deadpan look as she looked down to see her blouse swelling up. "OUCH!" Linda squirmed and fidgeted. "My bra is cutting into my…"
"...Your suddenly growing breasts?" Jess finished for her.
Linda nodded. She turned her back to Jess who reached up under her blouse and unhooked her Grandma's bra.
Linda let out a sigh of relief as her breasts continued to grow, filling out, smoothing out the stretch marks. Her nipples popped with vigor and renewed sensitivity. Her areolas widened as her swelling breasts pushed her bra up and out, the back straps dangled uselessly along her sides.
Linda pulled her shoulders backs and pushed her chest out. She was now much larger than she had ever been before in her life. A lifetime as a 34B, she was now a 36D.
Her breasts sat up higher, she felt the pull of them in the middle of her back "Youth" she thought feeling them bounce slightly even with just her breathing.
Jessica saw her chest transferred to her Grandma. She was taking away more and more of her features as she gained hers in return. The pit of her stomach quivered with fear and worry as she now felt her breasts drop, sagging into her cups heavily. Heavier than before even though they were shrinking smaller. Jess could see a gap forming as her bra puckered along the sides with her breasts no longer big enough to fill it out.
Her skin was wrinkling, stretch marks gouged in as her areolas shriveled and her nipples shrank down, flattening out. Veins appeared along the saggy and flattening bteasts as they retreated down and back; she longed for Linda's clothes right now.
Another thought hit her and she lifted up the bottom of her ill-fitting tank top. Her belly button piercing. Jess started trying to twist off the tiny knob on top buyer fingers had lost dexterity. She couldn't get it between them to turn it. Frustration started to.turn to panic as she saw the line of rougher skin creeping downward. "Oh...oh dear, um...Linda?! A little help!"
Linda had been lifting her shirt, examining her soft lined belly as her skin started to smooth and lift when she heard her name "Yeah Gram...oh jeez!" She hopped forward and deftly pinched and spun the top knob off, slipped the shift out and replaced the knob with a quick twist.
Jess sighed "thank you dear...I just couldn't get it"
"No probs…" she bounced the dangly blue piercing in her hand once before putting it on the dresser with all the rest.
"I'm going to be busy putting all those back in. What's it like for you to go through a metal detector? Haha" Linda laughed.
"It's not something I have to worry about currently" Jessica said speaking slowly and watching her stomach puff out into a lined pooch. Her belly button sank in as the piercing hole closed.
By the time Jess looked over,  Linda's had her blouse hiked up and tucked under her boobs. Her lithe hands worked over her stomach as it pulled up flat and taut with supple, smooth skin. The tiny piercing hole popped through and Linda laughed again giving her tummy a circular rub.
"You’re about to go through something that happened in reality to me 20 years ago" Linda said. "I don't know how that's going to go for you"
"And yours is going to,um...reverse itself?" Jessica fumbled a bit.
"Yeah so I apologize if I do anything lewd or embarrassing when it hits me. I nearly freaked out just getting your boobs haha. This is going to be In-Tense haha"
Under her khaki shorts, Linda's hips began moving outward, creating a definable curve. Her ass began to lift up, tightening from saggy to muscular round ball, desirable to so many. Her shorts strained against her body and it's changes. They grewbtighter and tighter as her curves accentuated and her ass filled out.
Once again, Jessica's changes were the reverse. Her hips narrowed and the fat on her ass overtook the muscle and it all drooped and sagged down, loose skin and all.
"This is really going to change us" she thought feeling a pulsation in her abdomen that rippled forward, pounding and thumping. "This is vitality, a very essential part of being or becoming our new ages" 
Linda let out a low moan. Her eyes closed and she bent forward pressing down on her abdomen "Mmmmmmmm...sorry...I…" her hand slipped lower and she pressed down harder. Her eyes popped open and she stared at Jess. "Sorry. I can’t…" she bit her lower lip, brought her knees together and stuck out her ass. "MMMMMMM! GOD! I can't fricking take it!"
A wet spot appeared on the outside of her shorts. Her right hand shot down inside.
Jessica smelled her excitement. The smell of sex, musty and familiar. A few ups and downs of her hand, then pressing down hard against her body.
Linda was on fire. Her entire body felt like a live wire with electricity pulsing through it. From the tips of her fingers to the ends of her still wrinkly toes back up to the last hair on top of her hair and everywhere in-between. Parts of her body that had been dormant at worst and merely functional at best were coming to life. She could produce eggs. Her uterus lining revitalized, fallopian tubes did as well. Her clit was on fire, demanding attention as her vagina and vulva restructured, moisture flowed to slicken the surfaces as they changed shape.
Jessica felt a cold numbness push through her like a lump of ice sitting in her abdomen emanating outward. Her productive eggs vanished. They jumped from her body to Linda's, landing inside her in multitudes.
A chain reacran down her fallopian tubes to her uterus which shriveled as 47 years transferred from her to Linda too. She had the internal organs of a 72 year old. As changes continued down, they also went up and around.
Down took them to her Vagina and vulva, even her urinary tract was affected. She felt dry, itchy even.
Up and around now affected all the rest of her organs. Her heartrate slowed, her lungs lost capacity, everything aged accordingly.
"I'm sorry but I can't…" Linda panted. Just a few twitches and pressure from her fingers and suddenly she convulsed. "Oh...ohgoddontstopdontstopmmnnnn" she looked over and then climax hit her. "Ah!" She straightened up, then crunched down as the smell of orgasm wafted out. A larger wet spot spread. 
Linda tensed and relaxed several times before it slowed and she got under control "I'm so sorry, that was embarrassing"
"No. It was necessary and I understand. There's no secrets between us now, there simply can't be after we've shared our entire bodies and minds with one another" Jess told her.
Linda unbuckled, unbuttoned and unzipped her shorts taking them down and off along with her panties. 
Jess got a glimpse of the weird demarcation line of their changes; old and wrinkly loose skin up her upper thighs but just above that, soft, supple and youthful skin and body.
Linda's thighs plumped. The skin stretched back out as fat and muscle filled in giving her healthy young curves. The changes continued down to her knees. 
Bony and knobby with loose skin sagging down. No more as they popped forward, the flesh tightening and full flexibility returned.
Jessica's thighs softened. The skin slackened and her knees stiffened internally as they loosened externally.
Linda's heart beat healthy in her chest as she drew in a deep breath and held it. Having the body of a 25 year old was enthralling even as it was overwhelming. 
Their calves began to change. The rougher skin continued down along with veins popping out with weaker muscles for Jess.
Smoother skin, defined muscle curves and even a bit of bounce came to Linda's changing lower legs. Her ankles strengthened as they trimmed down.
Linda quickly kicked off her shoes and socks, only their feet remained unchanged.
The rough skin doubled down on Jessica's feet. Her soles and heels hardened as her arches dropped to nearly flat. Veins again popped out as her toes began to kink and crook. Once again her nails thickened as the skin around them receded. The white polish moved through shades of pink to full on red toenails. Old lady feet.
Linda's arches lifted and once more dull and near constant pain vanished. "I Will not take this for granted. If it's an hour, a day, a week or...well, whatever. I will cherish being pain-free" she told herself, stopping herself though when contemplating a time frame.
The skin of her soles and heels went froma grayish white to a healthy pink. The tops of her feet smoothed out as her toes shortened as the straightened out. Her nails thinned down as her toes plumped and her nail color faded from red through pinks to bright white.
She wiggled her toes a bit frantically. 
"Is that? I think it's over…" Jess said "I feel different, like there had been an energy or something coming off of us and now it's gone"
Linda rubbed her eyes with thumb and first two fingers. "Yeah, it's hard to explain but I felt it too, like an invisible tension that's gone"
"Look at you" Jessica said and Linda looked down at herself.
"I'm you. I actually, physically turned into you. Every bit of my body transformed into yours. I'm 25" she said incredulously. "And that makes you my Grandma now"
Jess could only nod. "I went from being born in 1996 back to 1949"
"That’s incredible" Linda said. "So we switched places"
Jess nodded again. "We absolutely did switch places"
"Um, I don't mean to be rude but could you please give me your clothes...I didn't want to rush you but this is awful standing around full Winnie the Pooh in a top and bra that doesn't fit" Linda laughed. 
"Oh of course...how silly of me" Jess replied. She undressed but not quickly unlike Linda who now tossed aside her top and bra and stood naked in all her youthful glory.
She deftly reinsert all of her piercings, ears, nose, navel...and slipped on her rings as well.
Linda got dressed in no time and as Jessica went through drawers and the closet picking out a new outfit, she heard Linda running up the steps.
Fresh underwear, olive green shorts, a brown and cream loose blouse and new socks went on. She slipped the shoes back on grateful for their added arch support. She slowly climbed the stairs hearing a lot of noise from above. Boxes skidded, items clattered and she heard her former voice muttering. "Where is it? Where the HECK did it go?"
"What’s the matter sweetie?" Jess asked coming in the attic at last. 
"The statue! I can't find it!" Linda replied panicking and pulling at her curly hair.
"We just dropped it in the middle of the floor. It has to be right around here" Jessica replied.
"It's not okay! I came up here to get it and the floor was empty! I started looking everywhere but it's gone!" Linda said.
"Calm down honey, we'll find it" Jessica added.
"We have to find it! It couldn't just vanish!" Linda felt increasing heat and panic in her "if we can't find it, how are we going to switch back? We can't be like this...we can't, I can't " she started hyperventilating.
Jess walked over and took her by the shoulders and looking her inthe eyes said in a calm and steady voice "Don’t panic. Calm down. It has to be around here. We will figure out a way to switch back. Now it might not be immediately and it might not even involve that statue but it's going to be okay. You’re just worked up. Let's take our time and look"
4 hours later…
"It's gone" Linda said throwing her hands up, tears started flowing.
"Oh honey don't cry!" Jessica came over and wrapped her up in a hug. "I told you it's going to be okay and I believe that from the bottom of my heart"
"But it's not fair! It's not fair to you! I can't take your life" Linda cried and sat down.
"You’re not. You're borrowing it. This isn’t over. Not by a Longshot. I'm not giving up. We'll just have to find a different way back but until then, you have to be me. You have to be Jess. I have bills to pay, work to do and it looks like people will expect you, not me. I wet to try something"
"What?"
Jess picked up a pencil and a notebook and handed them over "Draw for me"
"But I can’t draw at all" Linda protested. 
"I think you can. Just let it happen" Jessica told her encouragingly.
Linda made a face bur sat down and began to freehand draw Spiderman with ease. She was shocked.
"See, we can do this. We have to do it. There's no alternative. We can't hide, we can't go back. It happened to us. For whatever reason, we swapped bodies. And lives. But also skills and everything else. We have our original memories and personality but we also have these new ones to go along with each other's body. We are going to figure this out. We will switch back but it's obviously going to take some time. We need to work towards our goal but, we need to also keep up appearances and that means living each other's lives like nothing is wrong"
Linda nodded.
"Can you do that? For me?" Jess asked.
"For both of us" Linda answered.
"And you told me you're in good health. We've got 20 years at least to figure this out" she joked. "It's getting late. Tony has already texted you"
Linda's chest fluttered hearing Jessica's boyfriend's name. "Check in on me tomorrow but you've got work in the morning and I know you can do it because, well, you're Jessica now just as much as I am"
The words sunk in. Linda stared but nodded "You’re right" she said. 
They said their goodbyes and Jess watched Linda drive off in her car. Jess was exhausted. She slumped into a chair and sighed "What a day...what an understatement" she put her feet up on the ottoman."How in the world did we end up this way?"
Jessica was tired, thirsty, hungry. Everything was catching up to her now that she was alone. Well not entirely alone. Her Grandma's cat now made her appearance rubbing up against her leg. "I suppose you're hungry too huh Lily"
"You missed all the excitement today but maybe that's a good thing. At least I'm still human. I could've swapped with you" Jess laughed. 
Getting up was an ordeal. Her back hurt, her knees hurt, her feet cramped and she heard several popping noises. "Oh my" she said shuffling to the kitchen. 
The pull tab on the can of cat food gave her trouble. She had to use a fork to get the tab up enough to get her finger underneath and then it took three tries to pull it open and her hands hurt afterward.
She drank some water and herself a cup of instant soup which filled her up.
She thought about venturing back up to the attic but decided against it for the time being. Instead, she showered and cleaned up.
It was the oddest feeling showering for the first time as her own Grandma. This was her body now. Old and wrinkly and frail. She was very careful stepping in and out. She took her time.
She put on a nightgown and started going through pictures before she fell asleep. 
Linda drove experiencing every possible emotion. Guilt, dread, fear, embarrassment, shame, trepidation, excitement, shame, joy, guilt, curiosity, arousement, embarrassment guilt and shame, acceptance, determination and finally confidence.
