Jenna and her younger brother Finn couldnât have been much more different, growing up they didnât share much more than a last name. But despite this, Jenna- the popular, outgoing, girly-girl and Finn- the shy, awkward gamer had become almost inseparable.
The two of them shared an apartment their parents had rented for them so they could have their own space. They both had busy lives, juggling collage, part-time work and seeing their friends (admittedly Jenna did a lot more of that than her brother) but whenever they had the chance the siblings would try to do as much together as they could.
On one of these occasions the pair had decided to visit an antique shop to buy some more decorations for their apartment, as they searched and picked out a few items Jenna noticed her brother had taken an interest in a strange looking trinket.
âPretty cool looking rock right?â Finn stated, inspecting the item in his hands
Jenna watched as he played with the stone, seeing the different internal layers move and spin independent of each other
âAs cool as a rock can be I guessâ Jenna shrugged, clearly not sharing her brothers interest in the item
âWhateverâŠIâm still getting it, itâs only 3 dollarsâ Finn remarked, placing the stone into their basket.
The two finished up in the store after grabbing a few more items, they decided to stop for some quick food before heading back home.
Later that evening Jenna was trying on some new clothes she had got delivered while her brother was in his room, presumably in the middle of another âgaming marathonâ or whatever he called it.
She opened one of the last packages and saw a racy matching bra and panty set she had ordered a few days prior, she was so excited to try them on she quickly stripped naked before pulling the two-piece on and checking herself out in her mirror. She was super happy with how they fit, she imagined what some of the boys in her collage class would think of this set. But before her fantasy could go any further she felt a sudden throbbing pain in her head. Jenna stumbled back from the mirror, she tried to steady herself but she had seemingly lost control of her legs. As she felt herself beginning to fall, her vision quickly dimmed and she blacked out before she even hit the floor.
Jenna took a sharp breath in, as she regained consciousness, still startled by her sudden fall that felt like only a moment ago. It look a second for her to gather her bearings but she found herself laying on her back in her brothers room. With each passing breath she managed to gather more of her thoughts. Why was she in Finnâs room? Perhaps he had found her unconscious after her fall and brought her here to rest.
Feeling well enough to move Jenna pulled herself to her feet but immediately noticed something was wrong, she felt taller and the balance of her body seemed off. She looked down to see she was wearing Finns clothing, her confusion only grew when she noticed how strangely the clothes fit her body, she reached at her chest but instead of feeling her soft breasts she could only feel the hard touch of her rib cage.
She began to panic, breathing faster, even her hands had changed, a horrible realisation began to dawn on her, she ran over to the mirror across the room and confirmed her fears. She wasnât just wearing Finnâs clothing, she was Finn!
Jenna screamed so loudly she was sure half of the apartment building would hear her, not that they would think the scream came from her given how her voice had changed.
âNo, no, no, no! Itâs not real! It canât be!â Jenna said aloud as her eyes began to well up with tears but with each passing moment it became more apparent that this wasnât some sort of twisted dream.
She laid in a heap on the floor, sobbing terribly, trapped in her brothers body. Minuets passed and all Jenna could do was cry, it took all of her strength to compose herself enough to think what might have happened to her real body.
Jenna frantically stumbled her way out of Finnâs room, down the hallway and into her room. As she burst open the door she couldnât believe what she was seeing
It was herself! wearing the lingerie she wore only moments ago. She wanted to say something but was completely lost for words and out of breath from sobbing.
âJenna is that you?â Her old body said to her, it was so strange to hear her own voice speaking to her
âY..yeah itâs me. Who are you? What happened? Jenna managed to string together the response
âItâs me Finn, Iâm inside your body, IâŠâ
âWhat the fuck? how could this have happened?!â Jenna became flustered again
âIâŠI was just playing with that stone then suddenlyâŠthe pieces all alignedâŠthere was this green light and then I was hereâŠin your bodyâ
âCan you change us back then?â Jenna questioned still distressed, she couldnât help but notice how calm Finn was being about this
âI think so, let me find the stone again and Iâll do what I did beforeâ Finn responded inside of Jennaâs body
The two returned to Finns room where he grabbed the stone from off his bed. Jenna watched as he rolled and twisted parts of it.
âThis should do itâ Finn quoted and with a final twist he clicked a part of the stone into place, the pair waited for something to happen but after a minute of silence a puzzled look came across both of their faces.
Again Finn tried to align the stone and again there was no result. He tried and tried but with each failure Jenna became more and more hopeless, she began to cry again an Finn dropped the stone back onto his bed in defeat.
Jenna slumped against her brother and began to sob uncontrollably again.
âWhat are we going to do?â she cried unable to cope with the possibility of being stuck in her brothers body foreverâŠ
Jenna hated every second spent in her brothers body but she still had some hope of changing back, Finn had been working on translating the old carvings on the sides of the stone hoping for a clue, heâd told her it was a mix of many different languages so it was taking a long time to make progress.
Jenna had just come in from grocery shopping when she found Finn, still in her body waiting for her in the apartment.
Jenna was finding it a little strange how fast Finn had become comfortable in her body and wearing some of her more slutty clothes.
âI can change us back!â Finn gleamed speaking in Jennaâs old voice.
âOh my god you figured it out! Yes tell me how letâs do it right now! God I canât take another second of thisâ Jenna was almost tearing up at the prospect of changing back
âYeah we can do it right now but thereâs just one issueâŠyouâre gunna have to have sex with meâ Finn spoke awkwardly
âWe have to have sex? Why?â Jenna said feeling deeply uncomfortable at the prospect
âThatâs just what it says on the stone. Listen I donât like the idea of having my own dick inside me just as much you donât want to fuck your own body but thatâs the only way youâre gunna get what you wantâ Finn explained sounding slightly irritated
âOkay fine letâs just get it over withâ Jenna said before the two of them entered her room and awkwardly stripped in front of each other
A few moments later Finn was laying naked on the bed as Jenna prepared to fuck him. She struggled to keep hard as she began thrusting into her old body, slowly, she built up a rhythm. Her pussy felt amazing around her cock but she couldnât help but notice the unimpressed expression on her old face. With a final thrust she exploded inside her body before a familiar pain in her head came over herâŠ
Jenna couldnât have been happier to be back in her own body. Sheâd all but moved on from the horrid experience with the stone and life was thankfully back to normal. Despite this she noticed Finn had been acting slightly different ever since their ordeal, heâd been a lot more distant since they switched back but she figured he was still wrapping his head around what had happened and hoped he would be back to his usual self soon too.
One afternoon Finn asked Jenna to driver her to a friends house and she happily agreed, not only was it nice to finally have him talk to her again but she figured him getting out the house and seeing some people would be good for him.
As she pulled into the drive she brought the car to a stop and waited for Finn to get out but he sat silent, looking troubled
âIs everything okay Finn?â Jenna asked, sounding concerned for her brother
Finn remained silent for another moment before speaking in a slightly pained tone
âIâm sorry Jennaâ he said reaching into the glovebox of the car before pulling out the green stone from his pocket âbut I need to have your body backâ
âFinn what are you doing with that! You said you threw it away!â Jenna said nervously
She saw him begin to spin and twist the stone in his hand she tried to quickly reach out and grab it but just before making contact with the stone a green flash shot out from the core of the gem
The now all too familiar pain flooded Jennaâs mind again as she flopped back into the seat, passing out.
Jenna awoke some time later laying on the floor of an unfamiliar room. As she regained he senses she realised she was once again back inside Finnâs body.
âYou know the week I spent inside this body was probably the best week of my lifeâ Jenna heard her voice say. She hadnât realised that her brother was in the room with her in her old body
âWhat the fuck! Why did you change us back into each other again!â Jenna said angrily
âAt first I was just as upset as you were about loosing my body. But then I got a taste of what youâve had all your life.â Finn turned to a mirror and began fixing his long hair as he spoke
âSee while you locked yourself in your room and cried like a baby I went out and enjoyed this body, and after we swapped back wellâŠI needed moreâ
âYou canât just steal my body! Weâre swapping back right now!â Jenna screamed furious with her brother
âI made the mistake of swapping back with you once, Iâm not doing that again. Thatâs actually why I brought you hereâ As if on queue, a huge, muscular man with dark black skin, walked into the room.
Finn turned from the mirror to finally look at Jenna
âThereâs someone Iâd like you to meetâŠthis is Tyson, a friend I made last time I occupied this bodyâ.
Finn gave a nod to the huge man and immediately he set after Jenna, she was no match for him as he pinned her down to the floor. Immobilised, she watched Finn approach her holding something in his manicured hands. He pulled down at Jennaâs pants revealing her cock, it would have been embarrassing enough without Tyson here to see but then she noticed what Finn was holding: a chastity cage.
Jenna kicked and screamed furiously as Finn began to fit the cage to her manhood, she knew what this meant there would be no way for her to change back if she couldnât use her cock.
âFinn please! Donât do this!â She shouted with tears forming in her eyes. Her brother looked up at her to make eye contact with her
âFinn?â he said questioningly
âWhy did you call me that? Iâm your big sister Jenna remember?â and with that statement Jenna heard a click and felt the cage tighten uncomfortably to her cock.
âNow Iâm going to give you two optionsâ her brother said holding the key to the cage in his hand.
â1-you accept that I am your big sister Jenna and youâre my pathetic loser brother Finn and I wonât throw this key down the drain and maybe once in a while Iâll allow you out of your cage to cum, it wonât be anywhere near me so donât get any ideasâŠor two you donât accept who you are and youâll spend the rest of your life trapped in that thingâŠyour choiceâ
Jenna was welling up, how could her brother be so cruel to her? She desperately wanted her body back but that seemed all but impossible now. Without the key there would never be a chance to escape this fate, but even with it she couldnât imagine Finn ever giving her the chance to fuck her.
âOkay I acceptâŠjust please donât throw it awayâ Jenna said welling up
âI want to hear you say it!â Her sibling snapped back at her
âIâŠIâm Finn, youâreâŠJennaâ she stuttered
âIâm Finn, youâre Jennaâ?
âIâm Finn!, youâre Jenna!â
âIM FINN YOUR LOSER LITTLE BROTHER AND YOUâRE MY BIG SISTER JENNA!â
There was a moment of silence as the siblings stared at each other.
Finn tried to hold back his tears as he lay pinned down to the floor, his sister stared at him with a smug grin. Jenna leaned in close to him to whisper in his ear
ââŠand donât you forget itâ she giggled giving him a kiss on the forehead.
âNowâŠâ Jenna announced âTyson youâve been so helpful I think itâs time you got your rewardâŠand Finn I know youâve never fucked a girl so I want to show you how a real man does itâŠâ
With that Jenna turned and began walking into the next room, Tyson followed dragging Finn along the floor, he couldnât believe he was about to watch his sister get fucked by a huge black man. He fought as best he could but soon he was in the bedroom with them and the door was locked shut behind him...
Finn was spending yet another night gaming in his room when he heard the familiar vibration tone of his phone going off on his desk. He turned his phone over to check it and saw a text message from Jenna
Hey loser! Iâm having Tyson come over soon to fill up my holes again, how do you like my outfit? If you promise to be quiet and not leave your room Iâll take a day off your next chastity release! Have a nice night try not to get too horny listening to us ;)
