Vince was fuming. His little shit of a brother was fucking his life up. Vince was quite intelligent and was preparing to go back to school to get his degree in law, while his brother was quite dull and full of rage. He was often the cause for a lot of their fights. He desperately wanted to be rid of him so he could carry on with his life normally. Rummaging through the attic for his belongings, Vince stumbled upon a hidden strange device. It looked kind of like a gun, but it was more futuristic-looking. There was a small screen on the side of the gun, but it was empty. Turning it over, a label read "Role Reverser". Unsure of what the device was actually meant for, he figured he's keep it handy, just in case his brother tried to pick another fight.
Right on cue, Tony waltzed into the attic, his face red with anger. It didn't take long for him to start screaming profanities at his brother once again for taking up all the space in the attic. Fed up with his bullshit, Vince pointed the gun-like object at Tony and pulled the trigger.
Time seemed to stop for a moment. Well, at least Tony was frozen in place. The display on the side of the gun lit up and started taking down information about Tony, such as his gender, weight, height, hair colour, etc. Even personality traits and personal details about him were showing up, like his temper issues and his hatred for his brother. Just about everything there was to know about Tony was appearing on the device. Once the progress bar reached 100%, all the information inverted. His gender changed from male to female, his hair colour from brown to black, skin colour from white to black, his sexual preferences from female to male, anything and everything the device had tracked about Tony was completely opposite on the screen now.
Vince looked up at his brother, who he noticed was beginning to change too. His hair began the darken until it was a pitch black, and soon his skin followed, becoming a light chocolate. His stature became more petite, standing at a measly 5'5" compared to his previous 6'3". His eyebrows became flawless, as did his beautiful brown eyes. Nose narrowing to create a perfect bridge, his mouth plumped up slightly, giving off a sultry look. With a fully feminized face, Vince drew his attention to the swelling masses growing on his brother's chest. They weren't huge, but they were definitely recognizable as sizable tits. His waist slimmed as the hair that used to be present on his back and chest seemed to vanish. The bulge in his crotch shrunk until it was non-existent, which Vince could only assume meant his dick was gone, replaced by a pussy. His wife beater and jeans were replaced by a beautiful black tube top and skirt along with matching heels.
What Vince didn't see was the changes that happened in Tony's mind. He no longer felt like a Tony, nor even a "he", but rather she was Tori. Everything about Tori's thoughts were flipped including her sexuality. Instead of loving fucking tight pussy like Tony, she loved fucking huge cocks. But most importantly her hatred for her brother was gone, replaced by love. When her IQ flipped from 85 to 130, she recognized the situation she was in and with her new quick thinking skills she devised a plan.
Eyeing up her white brother, a look of evil lust smeared across her face, and with a beckoning finger, she lured her prey in. "Ever fuck a black woman before big brother?" she asked coyly, kicking her heels off and sitting down in a chair. "Well here's your chance. Worship me and I'll let you fuck me."
Confused but not wanting to miss his chance, he obeyed and dropped to his knees to worship the feet being flaunted in front of him. Vince found himself getting really turned on, rubbing and spitting on the feet of the Goddess sat before him. He didn't care that this woman used to be his brother, right now she was his lover.
"Good job Vinny, now let me get a taste of that cock of yours. Y'know I'm a real sucker for big cock now, so if you're anything close to how big I used to be, all will be fine." Allowing her sibling to rise to his feet, she waited impatiently for him to make his way to her chair. Upon arrival, she fought aggressively with his jeans, unzipping and unbuttoning the prison guarding her prize. Yanking his pants and underwear down in one swift motion, her jaw dropped. "God damn this thing is massive!" she said, drooling slightly. In an instant, the meat stick was lodged in her mouth. Sounds of wet sloshing and slurping filled the room as Vince started to moan. This was the best head he's ever gotten in his life!
With one hand on her brother's cock and the other squeezing her own fat ass, the egotistical bitch moaned hard when Vince grabbed her head and forced it farther onto his dick. "Easy baby, a girl can only take so much at once!" Groping his balls while she continued to work her magic, Tori started to feel a burning need in her new pussy, a need that was so familiar, yet never felt before. A need to be filled.
"Vinny baby, I need to be a good big brother and fuck my pussy, kay?" she ordered. Vince was lost in the heat of the moment, he didn't care what she asked of him, whatever it was he'd do it for her.
He picked the bitch up off the chair and tossed her onto the nearby couch. Joining her, he eased his dick into her dripping slit, having a hard time penetrating. "God damn you're tight as fuck, guess that makes sense seeing as it's your first time" he said, finally pushing his way into her. Quickly, he began to pump in and out of the slut, her moans increasing in pitch and volume.
"Fuuuuuck yes Vinnyyyyyy, fuck your little sister sooooo good!" she screamed at her lover, feeling waves of pleasure blast through her young and nubile body. Reaching her climax before Vince, she realized it was time to finish what she started.
"Pull out baby, I want you to cum on my feet" she said seductively. Vince was more than happy to oblige. Removing his dick from her snatch, he started jerking it. He was close to cumming, but he needed a little more convincing from his hand to get the job done.
While he was distracted jerking his dick, Tori found the "Role Reverser" Vince had just used on her. Now that she was a brilliant young woman rather than a dull young man, she knew what this device was used for. Pointing it at Vince, she pulled the trigger.
"Vinny baby, I love you, but I know what you did to me. Believe me, I love the new me more far more than the old me, and that's why I'm returning the favour. See you in a few, sister."
Without much time to react, all Vince let out before he froze was an exasperated "NOO!" The display on the device lit up once again and Tori watched excitedly as her brother began his transformation. The first noticable change was his skin colour, rapidly darkening even moreso than Tori's. His hair, however, didn't become quite as black, but rather a long dark brown with slutty fading blonde dye. Despite being older, Vince actually ended up a few inches shorter than his sister, standing at 5'3". His masculine features shifted to become more and more feminine, eventually settling in on a beautiful 20 year old black woman's face. His body hair disintegrated while it reshaped itself, giving him an hourglass-like shape. Just as had happened to Tori, his skin expanded in the appropriate places for a young sexy woman like herself, her chest growing titties that matched her sister's, while her ass became bigger, but not quite as firm as Tori's. His dick receded into his body, cum dribbling out from being unable to finish earlier. All that remained in it's place was a perfect vagina, just begging to be explored. Completing the image of the beauty, his clothes turned to shreds, replaced by delicate lingerie.
Not long after his body was complete, his mind diminished. Vince was gone, and Victoria took over. Thoughts of hot girls and despising her sibling were reversed. Now her brain was full of hunky men and a new love for her sister, now her best friend. Together the two girls had fucked and sucked so many guys they had lost count. Vic was so glad her sister was in her life. Thinking was sooo hard for her now since her IQ dropped by about 50 points. Her sister was so smart and always knew how to lure men into their trap.
Vic's transformation was complete. Without a second to spare, the front door opened. Peering down the hall, the girls saw their father. With her quick thinking and a smug look, Tori grabbed her bimbo sister by the wrist and dragged her down the hall to introduce themselves.
"Who are you, and why are you in my house?" he asked, somewhat scared of the duo of strangers in his house.
"We're friends of Vince and Tony, but to you we're your dream come true" she responded, eyeing her father from head to toe and licking her lips. "You like what you see?"
"Uhh...well...I'm married-"
"That's not what I asked."
"Yes, I like what I see."
"Good. Do we make you hard?" Tori asked in a sexy tone, already knowing her father's response.
"Absolutely." His trousers outlined a noticeable bulge.
"God damn honey that thing looks bigger than the last cock I had. Mind if we take a look?" She already had her hand on his bulge while Vic grabbed him by the head and pulled him in for a kiss. He didn't fight it.
"It's all yours." The girls sank to their knees for their dad, both latching onto his pants. Tori was very particular and methodical in disassembling his belt, while Vic was more hasty and clumsy, grasping for her dad's cock before it was revealed. It was her first since the transformation and she couldn't be more ecstatic. Exposing his member, the sisters gasped at the sheer girth of it. It was definitely bigger than Vince's.
Vic couldn't take it and tried to jump on the man, but was pulled back by Tori. "Not yet, me first" she demanded. Upset, Vic sat back and watched as her sister layed on her back to take the etirety of her dad down her throat. She couldn't just sit and watch though, so she decided to eat her sister's pussy for her. It's what a good sis does after all. The girls moaned and groaned in their incestuous threesome, part of the pleasure coming from the fact that their dad is cheating on their mom, part of it knowing their dad doesn't know he's fucking his daughters.
Tori decided to treat her sister. Removing the cock from her wet sleeve, she told Vic to get on all fours. Vic was giddy, complying with everything her sister asked of her. "Fuck her doggy style daddy. Careful, that bitch is tight." Without hesitation, he slipped his saliva-covered cock into his daughter's soaking cunt, feeling her vaginal muscles squeeze the whole way. Vic let out a loud moan as her feeling of emptiness disappeared. Tori stood above her sister, ass sticking out towards the man's face. "Now eat my ass while you fuck."
The man had never eaten ass before but he felt he had an obligation to. Not second guessing himself, he dove his face into Tori's asshole, tonguing her hole like he would his wife's pussy when they were teens. Tori looked down at her sister who was lost in the pure ecstasy of the situation. Smiling, she knew she had corrupted both her sister and her dad beyond repair.
Seeing her dad start twitching, Tori knew he was about to bust. "Pull it out and cum for us daddy" she begged, lying on her back with her tits in her hands. It didn't take long for him to glaze Tori with his sticky seed, Vic trying to intercept the cum with her mouth.
Laying in the hot mess they created, Tori looked at her sister's cum-covered face. "Guess we don't need to fight over daddy anymore." Gone were the days of their family rivalry, the brothers-turned-sisters were closer than ever.
