It was a normal day. Nothing unusual. The sun was out; the air was clean and calm. Not a cloud in the sky. You would never expect anything out of the ordinary to happen. And yet something no one could ever expect would happen in this normal family of six involving two of its members.
Joe was the big brother of the house. He was on his way to a nice college and he was the very picture of a healthy young man. 18 years old, six feet tall and 160 pounds. His dick, 13 inches erect, was his pride and joy. He had a little sister named Lucy. She was 9 and like any nine year olds, she was a petite 4 feet, 65 pound girl just on the cusp of puberty. To say they were complete opposites was not an exaggeration and that why what was about to occur would be quite the shock for both of them.
"Come on and hurry up! We're gonna be late!" Joe yelled to his little sister. They were ready to head out for the younger sibling John's baseball game. Joe stayed behind as Lucy needed to get ready. "I'm coming, I'm coming!" Lucy shouted out in turn. She came running down the stairs. "Took you long enough..." "Well sorry!" Lucy sniped back. "Maybe if you were the little girl, you'd understand!" "Yeah, yeah. I would kill to be a pipsqueak again, but we can't get what we wish for all the time, so let's just get going." Joe started walking towards the door. "Hmph!" Lucy puffed her cheeks in a small fury and followed her brother when she saw the impossible.
"Joe!" "What?!" Joe kept looking forward. "You're... You're floating!" "Floating...? What...? AH!" Joe looked down and saw the impossible as well. His feet were above the ground. His socks and shoes on the floor in a pile. He looked down and wiggled his meaty toes in order to process that this was really happening. "Ah! Lucy?!" "Joe?!" Lucy ran toward her brother, but soon found herself in the air. "Ah! Ahhhhhh!" Lucy screamed in a high pitch. Like Joe, her socks and shoes were left on the ground leaving her barefoot. "Joe! Joey!" "Lucy?! Ahh! Whoa!" Joe's body jerked backwards, as his pants were ripped off his body, leaving him in his boxers. "Joey! Waaah!" Lucy moved closer to her brother as gravity claimed her own pants. The invisible force swirled their bodies around. "Lucy?! Ah!" "Joey! Ah! What's happening?!" "I don't know! Whoa!" "AHHHHHH!" The sibling yelled out as their bodies twirled upside down. Joe's shirt covered his face showing off his 10 pack abs and eventually his massive pectorals. His shirt fell to the floor as he watched in horror as his sisters mostly naked body was exposed to him. "Lucy! Oh my god!" "Joey! Joey, I'm scared!" "It's alright! It's al-riiiiight!" Joe and Lucy's body made another flip upright. They were both naked except for their undergarments. "No way!" Joe was the first to realize what was to occur next as he felt a tug near his waist. "Oh shit!" Joe couldn't help, but curse in front of his baby sister as his boxers left his legs and Lucy's panties soon followed. Joe's dick, soft at 7 inches, was flopping in open view of Lucy. "Joey! Whoa!" Lucy looked in slack jawed awe. She knew boys had something between their legs but compared to John, this was huge.
"Lucy?! Oh god! I'm sorry you have to see this!" Joe was embarrassed by his sister staring at his package. "Joe! Your thingie! It's... growing!" "Growing?! Ah!" Joe looked down to see his dick was indeed growing in size. It pulsed as blood went through his shaft, making it erect. It wobbled up and down, as precum leaked from his peehole. "Jesus!" Joe couldn't understand what was happening to his body. He felt all hot and tingly as if he were in the middle of jerking off. "Ah... Ah... Ah,ah,ah,ah,ah,ah,ah,ah,ah,ah!" "Joey?!" "Ah,ah,ah,ah,ah,ah,ah!" Lucy watched in horror this time as her brother's body, along with his enormous pee-pee shook uncontrollably. "Ah,ah,ah,ah,ah,ah,ah,ah! Holyyyyyyyyyyyy! Ah,ah,ah,ah,ah,ah,ah,ah! Holy crap! Holy crap! HOLY CRAP!" "Joey?! What's happening?!" "Ah,ah,ah,ah,ah,ah! My dick! My dick! Oh my god! I'm gonna blow! Ah,ah,ah,ah,ah,ah,ah,ah,ah!" "Blow?! Joey!" "Oh my god! Oh my GOOOOOOOOOOOOOOOOOOOOD!" Before Joe could answer, a white liquid furiously erupted from his penis, spraying the house and Lucy with a sticky fluid. "Bleg! Gross!" Lucy shut her eyes as the goop poured onto her. "Ahhhh... Aggggggghhhhhhhhhh! My dick!" Lucy could only here Joe talk about a dick. She wondered if it was another name for his penis. She soon felt the liquid no more. She opened her eyes and saw her brother's penis spurt out more of that white pee. His face was flushed with ecstasy. "Holy crap! Oh my god!" Joe's dick soon stooped leaking, though it remained hard and tall. "Joey? What... What was that?!" "Oh my god! Lucy! I'm sorry you had to see that! Holy shit!" "Joey..."
Lucy looked at her brother with sadness. It looked like that really hurt. She looked down as the white liquid drizzled onto the floor. But there, she was met with a sight even more bizarre sight then before. "Joey! Your feet!" "Ah... My feet? What about my.... What the hell?!" Joe looked down at his feet and saw the skin bubble and morphed. He felt his skin and bones retract into his body. The toes on his feet shrunk one by one. The tan dissipated as his once big meaty feet became dainty and petite, almost like a little girl. "Holy Shit! My... My feet!" "Joey! Waaaaaaah!" Lucy felt her legs move up as her body lurched into an obtuse angle. "Yaaaah!" "Lucy!" Joe could see her feet in front of his face. He looked down again at his own and saw that they looked familiar. They were his feet now! He looked upwards again as he watched as her toes seemed to get closer. Lucy looked upwards and saw her tiny feet double in size, a significant tan color washed over them. Each toes bulged out of her sockets as her feet became firm and meaty. Joe looked straight at them and understood what was happening. "Holy crap! Lucy! We're switching bodies!" "What?! Joey! Ahhh!" Lucy's legs flipped straight again as Joe felt another surge in his dick. "Ah,ah,ah,ah,ah,ah,ah! Ah,ah,ah,ah,ah,ah,ah! Shit! Not again! Ah,ah,ah,ah,ah,ah,ah,ah,ah,ah!" "Joey! Joey, ahhhhhhhhhhhh!" Lucy felt her hands tighten as they slowly expanded. She clasped them together as newfound strength pulsed through them. Hair grew from her knuckles and back of her hand. "Ah,ah,ah,ah,ah,ah,ah,ah! Lucy! Ahhhhhhhhhhhhhhhhhhhhhh!" Joe ejaculated once more. As more white hot cum shot through the air, his hand shrunk back into his arms. He could feel the strength leave them as the body hair receded inwards leaving his hand dainty and shiny.
"Joey! Joey! I don't wanted to be a guy! Help!" "Ah! Lucy! I'm sorry Lucy! Oh my god!" "Ah! Joey!" "Ah! Lucy!" Lucy could suddenly see higher and Joe could no longer see as high. They looked down to see what they were expecting. Lucy legs were moving up from her ankles as Joe's moved into his tiny feet. At the same time, their arms were making the same metamorphosis. Hair was leaving Joe's hunk of a body, while hair sprang all over Lucy's body like she was becoming an caveman. They looked straight and gasp once more in horror. "I'm at your eye level, Lucy!" "No way! Joey!" "Ah,ah,ah,ah,ah,ah,ah,ah,ah!" Joe once again started his mysterious masturbation session. "Fucking hell! Ah,ah,ah,ah,ah,ah,ah,ah,ah! Fuck, my dick!" "Joey! Agh! Ohhhhhhh" As Lucy watched her brother shaking she felt a dull pain wrack her body. "Ohhhh! Joey! I don't feel good..." "Ah,ah,ah,ah,ah,ah,ah,ah,ah! Lucy?! Ah,ah,ah,ah! Holy... Holy shit!" "Joey! Hmph!" Lucy felt her right arm tense up and spaz outwards. She caught a glimpse as her skinny arms expanded and bulged with new found muscle and sweat. "My body! Joey, my body is... Hmph!" Her other arm followed suit. It felt as if her arms were filled with lead. "Hmph! Uguuuu!" She made incomprehensible noises as her legs also blew up with muscle. Through his ecstasy, Joe could see his baby sister with the torso of a little girl, but with the appendages of a muscle god. He knew what was going to happen next as he cummed once more. "Holy Craaaaaaaaaaaaaaaaaaaaaaaaaaap!" Joe's body shook as the muscles on his arms and legs detracted. His well earned body was looking more like that of a little punk. "Ah... My body... My beautiful body... Lucyyyyyyyyy!" "Joeyyyyyyyyy!"
They both yelled out to each other as they next changes took form. Lucy suddenly had to look down as her brother's face was lower then her own. Likewise Joe had to jerk his head up to keep with his sister's face. "This can't be happening! Lucy!" "Joey?! Ahhhhhhhhhhh! Joe looked back straight again as he saw his sisters stomach shift. "Ohhhhhh... My tummy doesn't feel so good..." "No way! No fucking way!" Joe knew what was happening. He watched his sister's tummy as several small rectangles of meat came to the surface. Each one built up from the other, two side by side and five all the way up. A ten pack of abs had formed on Lucy's stomach. Joe looked down as his abs, now on Lucy's body, removed themselves from his own. His pectoral muscles sunk into his chest as it became flabby and formless, not yet breasts, but still not male tits. Lucy watched the changes on her brother's body as she felt another dull pain on her breasts. "Ah... Oh... Hmph! Hmph!" Lucy felt her chest burst as two square shaped masses bulged from her body. Her nipples also grew wisps of hair. She looked like her brother a lot, only with the face of a girl and hole between her legs. She looked at Joe, his big head rested on his small, girly body as the slab of meat pulsed between his legs.
"Oh my god! Oh my god! Lucy?!" "Joey... Don't worry. It will all be over soon." Lucy tried to reassure her brother seeing as she would be his elder soon. Lucy looked to his face as the skin looked like it was starting to pop. "Joey! You're face!" "Lucy!" It was then that Joe could feel his face burn up. "Agggggggh! Waggggghagh!" "Joey!" "Lushi! Mew fawce! Mew fawce! Agggggggggggaaaaaah!' "Joey's face looked like an allergy had struck him. His face bubbled and contorted in pain. "Joey!" Lucy could only look on as her the hair on her brothers head jutted from his skull, his hair turned a light shade of blond and this bulge on his neck disappeared into his throat. "LushiiiiiiiiiiiiIIIIIIIIII!" Joe screamed out his sister's name once more as his voice went higher in pitch. His face cleared out as Lucy gasped. Her brother's face looked like her own. "Joey! You... You got my face!" "Holy shit! Fuck, fuck, fuck!" Joe cursed his lungs out. His little girl voice sounded strange spouting those vulgarities. "Joey... Ugh... Ugh... Gaaaaaaaaaaaaaaaaaaaaaaaaaaah!" "Lucy!" Joe watched in horror as his sister's face bubbled this time. "Joheey! Joheey! It hurwtsssssssssssssssssss!" "Lucy! Lucy! Just stay calm. Just stay... Ah,ah,ah,ah,ah,ah,ah,ah,ah! No! Not again! Ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah" Joe once more felt the need to cum. His little girl face contorted once more in ecstasy. "Joheey!" "Ah,ah,ah,ah,ah,ah,ah,ah! Holy shit! This is a big one! Goddamn, my dick! Ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah!" "JoheeeeeeeeeeEEEEEEEEEEEy!" "Lu... Lucccccccccccccccccccccccccccccccccy" Joe ejaculated once more just as his sister's face finished its changes. Her voice bellowed in a deep masculine pitch. Joe continued to shoot his load. It lasted longer than all the others, but eventually it stopped shaking. "Oh my god! I think I cummed my whole dick out..." "Cum? Was that that white stuff?" "Yeah... Jesus Christ... I made a mes..."
But before Joe could finish his sentence. The cum strewn around the floor and on Lucy's body started moving. A steady stream of it whipped around and between the two of them and moved towards a target: Lucy" "Joey?" "Lucy... Umm..." They stared, mesmerized by the stream of white cum, unable to process what was about to happen. The cum shot into Lucy's vagina. "Holy..." was all Joe could muster. "Ah... Ah... Ah... Joe... Joey... AH... AH....... AHHHHHHHHHHHHHHHHHHHHHHHHHHH!!" "Lucy!!" "AHHHHHHHHHHHHHHHH! Joey! My insides... My insides are burning up... Uggggggggggggggggggggghhhhhhhhhhhhhhh! Ohhhhhhhhhhhhhhhhhhhhhhhhh!" "This isn't happening! This isn't fucking happening!" Lucy felt the cum shoot into her inside. Her body jerked up as her firm, hot ass undulated in the air. She could feel something form in her insides as if the cum was creating the start of something inside. "Uguuuuuuuuuuuuuuuuuuuuh!" Lucy shouted out the one more moan/scream as the cum finished its journey inside her. Her body moved back downwards and everything became quiet. "Lucy... Are you... okay...?" "I... I think... I'm fine. My insides feel heavy, but.... UGH!" Without warning, Lucy's pelvis thrust into the air. "NO... WAY..." Joe could only watch as his sister thrust to the ceiling several times. "UGH... UGH... UGH...! Joey! UGH! I feel something... UGH... coming... UGH!" "Fucking hell!" was all Joe could muster as Lucy thrust once more. "UGH... I feel it Joe! Big brother! I feel my... DICCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCK!" Lucy thrust one last time as she yelled out in her biggest manly voice. Joe watched in horror as two ball shaped sacs of skin descended from Lucy's clit. The baggy skin produced a bushel of skin. "Hmmmmmmmmmmmmmmmmmmmph!" Lucy made a discomforting noise as Joe saw something shaped like a mushroom push out of Lucy's vagina. "Holy shit! Holy shit!" "Hmmmmmmmmmmmmmmph!" The mushroom pushed out into the open, bring a fleshy and pulsing stem from her groin. "Oh my god! "My sister is getting fucking cock and balls!" The stem continued to slither out of the body. Lucy went through an enhanced puberty as her newfound dick went erect. "Hmmmmmmmmmmmmmmmmmmmmph!" As soon as it reached the respectable 13 inches, Lucy stopped groaning. Her body went limp once more. "Lucy?" "Ah... Ugh... Joey...? That hurt... Ah!" Lucy looked down as her new package. She poked on her erect dick as it flopped up and down and leaked precum of its own. "Ahh... Ah... Ah..." "Lucy?!" "Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!"
"Ah! Lucy! Lucy, calm down!" "Calm down?! I have this... thing...! Between my legs! I have a fucking dick!" "Hey! Language!" "Oh my god! Ew!" "Lucy, its not that... Ah!" "Hmm... Joe?" "Ah... ah...ah..." "Oh... Oh shit! Joey!" "Ah... Lucy... Ah..... Oooooooooooooooooof!" Joe made noise as if he was hit in the groin with a ball. "OoF... OoF!" "Joey... Ah... Ah... Ah,ah,ah,ah,ah,ah,ah,ah,ah!" Before Lucy could ask what's wrong, she felt her dick pulse like mad, causing her to thrust in the air. "Ah,ah,ah,ah,ah,ah,ah,ah,ah,ah! Joey?! Ah,ah,ah,ah,ah,ah,ah,ah! I think that thing is happening! Ah,ah,ah,ah,ah,ah,ah,ah,ah!" OoF... Lucy... OoF... Lu... CCCCCCCCCCCCCCCCCCCCCCCCCCCCY!" Joe felt the inside of his body trying to suck up his dick. His childish buttocks shook violently in the air. He tried to look down and caught a glimpse of his dick soften back to seven inches. But it continued to shrink to six, to five, to three inches. "No! No! My dick! NOOOOOOOOOOOO!" "Joey! Ah,ah,ah,ah,ah,ah,ah,ah,ah! Joey! I feel so hot!" "Lucy... Ugh..." Joe tried to talk to his sister but his dick shrinking was distracting. He could no longer see it as it came down to 1 inch long. He could feel the tip of his dick plop back inside. "Oof!" An extra kick and his testicles followed suit. The bush of hair that adorned his groin was no where to be seen. "Shit! Mother fucker!" Joe felt his insides rearrange as his dickless hole formed a child size clitoris. The pain subsided as Joe went limp himself. "My dick... Goddammit.." "Joey!" Joe heard his voice from his sister's mouth. "Oh crap! Lucy!" He looked up as Lucy continued to thrust her dick up and down. "Ah,ah,ah,ah! Joey! My dick feels all warm... What... Ah,ah,ah,ah,ah... do I do?!" "Oh god! Don't fight it! Just let it all out. There's nothing to be afraid of!" "Ah,ah,ah,ah,ah,ah... Really...?" "Yeah. You're... a guy now. And when your dick feels all nice and warm, that's when you ejaculate!" "Ejaculate? Ah,ah,ah,ah,ah,ah,ah... Oh... Okay!" "Oh god..." That was all Joe could say as he watched his sister go through her first erection. "Ah,ah,ah,ah,ah,ah,ah,ah,ah,ah! Oh my! Oh my god! Ah,ah,ah,ah,ah,ah,ah,ah,ah! Oh shit! I feel it Joey! I feel something coming!" "Lucy! Lucy!" "Ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah,ah! It's here! I'm gonna... gonna ejaculattttttttttttttttttttttttttttttttttttttttttttttttttttttttte!" Lucy thrust once more as she shot her load all over. "Holy... Moley!" was all Joe could say as he was hit by the white hot spunk that was once his. "Ah... Ah... Ohhhhhhhh... Joey... That... was AWESOME!"
Lucy pumped her fists as her dick shriveled back to its original seven inch size. What ever was moving their bodies gently planted them on the ground. Their bare feet touched the cold, cum stained floor. Lucy walked up to her brother. Joe shot a look of confusion at his little sister now his big brother. "Guess you get to be me huh... Lucy!"
