Sisters are innocent flowers that needs protecting

Alice huffed as she walked over to the upstairs bathroom, glancing back to see the feminized Alex bring a stool from her room to sit on in the hallway. As Alex moved up, she didn't notice that Alice had stopped in the hallway and nearly bumped into her. Alice caught her gaze and she gave her an apologetic smile and giggle.

"Sorry, didn't see you there," Alex added as Alice caught herself staring at this new version of her brother. She even smelled nice! She was also kind of cute and submissive in a way she enjoyed, but then she began blushing and stepped away.

"Play some music while you're sitting here," Alice said to her dumb little sister as she stepped into the bathroom.

"Careless whisper?" Alex asked and giggled as Alice with a flat look on her face rolled her eyes and slammed the door shut, locking it firm.

Then Alice took a long sigh and shook her head, leaning against the door for a moment. "Sure, I'll jerk off to turn you back into a dude, no problem," Alice said to herself in a quiet voice. "So your friends won't turn you into their personal cum dumpster when they arrive in a short while. No problem!"

She sat down on the toilet lid and put her head in her arms. She began pondering a way to get her engines going and tried to remember a recent thing she'd been aroused by.

Images of cocks coating her new sisters body in fat ropes of cum began rolling through her head. She could argue she had a thing for dicks ejaculating over women. Sometimes she was curious what it would feel like to be coated while on her knees in front of a dozen guys, but also how it would feel to rub a fat cock in a girls face before coating her in her own musky seed.

Alice slid a hand under her shirt and began rubbing at one of her tits, the other hand sliding down her leggings and began rubbing at her engorging nub. It might not be a perfect start to this masturbatory adventure, but it was liftoff she reasoned.

'Now, how to drop by step brother land...' Alice thought to herself as she continued teasing herself. She imagined stuffing herself into a laundry machine, getting stuck and calling for her brother. "Alex, I'm stuck, help me," She called out in her visuals, dressed in nothing but a loose t-shirt and some boy-shorts that were barely hanging on.

high heels clacked down the stairs and into the laundry room. "Oh my," Alex girly voice said and giggled as she came up behind Alice. "Step-sis, what are you doing getting stuck in the laundry machine," Alex said as she put her hips up against Alice butt, no bulge intrusion detected.

Alex' titties pressed against Alice' back as Alex snuck her hands into her boyshorts, tugging at her engorging clit, foreskin sliding up and down between two gentle fingers. "Someone's getting turned on by this," imaginary Alex said as Alice began huffing and moaning. Alex' other hand slid inside her boy-shorts as well, grabbing hold of a sack and caressing a pair of fleshy orbs contained inside.

Alice eyes snapped open as she mentally returned back to the bathroom. Somehow she'd was leaned over the sink in the same position that she'd been maintaining in the laundry machine. She was also naked and her left hand was jerking a very large, skin covered and pleasurable clit. Tugging skin up and down the rod, sack bouncing up and down with her jerking fingers, the uncircumcised foreskin rolling on and off her clit head.

Oh, who was she kidding. She was fapping a massive girl cock. Her own girthy girl cock! A cock she'd had years of fantasies about jerking off with. Her slit had been pulled out of her body and turned into a foreskin, taint, dick skin and nutsacks. Her ovaries had been exiled from her abdomen and converted to precious and churning testicles.

She glanced up at herself in the mirror in front of her, assessing the damage and hoping to find strength to stop jerking her new toy. Her legs were growing longer and her body was gaining muscles. Her shoulders were widening. Her tits were inflating with silicon implants and her face gained a hint of savage masculinity. Her hair turning fake blonde like her sister's.

"Oh shit," Alice said in a darker voice and let a moan slip by. "Fuuuck, no... I'm going to- unf!" she said to herself in quite a loud voice, hoping maybe Alex would knock and distract her enough to stop these changes happening to her.

But it was too late. Her balls grew a little more, gaining super human traits, and a new massive prostate began twitching, tugging her ball sack up and sending a flow of nasty cum down her fat cock. Alice gasped as her new muscles spasmed violently, the sound of cum ropes hitting the floor and the drawers under the sink, sizzling and spattering loudly onto whatever was in the line of fire of her cock.

After a dozen godlike ejaculations onto whatever was in front of her, Alice took deep gasps of air and wiped some sweat off her forehead. "Holy shit, what the fuck," she said once, then a few more times as she stood up, turned around the room. She looked at herself then she looked down.

As she casually played with her new cock, a corset manifested on her chest, along with various jewelry. A tan darkened her skin with the exception of a bikini pattern, and a smirk grew on Alice's face.

She wasn't old innocent and prudent Alice anymore. She was a proud and hungry dick girl, looking for asses to plow and wombs to impregnate.

"Hey, are you doing okay in there, sis?" Alex asked through the door. "it just sounded like there was... an event and I don't see anything has changed out here."

Alice huffed as she looked at the door, pondering what to say to her sister. Or to be more precise, what to do.
