From Queen bitch to Cum Queen.

John was in luck, his sister had chose this moment to come back to her room. Walking down the hallway past his just as he was walking out. Your voluptuous twin sister, popular and well liked with a killer body that drew so many heads. She was known for figure, her good looks and how she carried herself with that "I know im so damn hot" confidence.

She had boys eating out of the palms of her hands like a flock of horny geese, something that really irritated John. He wondered what a few little changes could do to her.

Before she even had a chance to notice him standing in his doorway, the device was at hand. He cycled through his phone for the perfect pictures and locked the concept and ideas he had in mind. Gwen looked up just about to open her mouth when he fired the gun.

Zzzzt!

John blinked once and opened his eyes, nothing had changed. She was still about to open her mouth and no doubt say something derisive towards him when he caught it, right at the edge of her lips. A thick viscous white stringy goo sealed her lips, she had to suck back the substance in her mouth in a very unpleasent fashion. Meanwhile she glared at him, then reached into her pocket and pulled out wad of tissues from her back pocket. She wiped at her mouth, long strings of sticky white slime coming off her lips like it was practically dripping off her mouth.

"What are you staring at dip shit?" She spoke with a slight lisp, like her mouth was filled with too much maple syrup or she was trying to speak with a cold and had too much mucus in her nasal cavity. John just smirked, enjoying the show. She was obviously annoyed, and it showed but her ability to talk down to him was hindered by the mere fact that her salival glands now produced large quantaties of semen and sperm instead. John took a step back as she got closer to him, she smelled like the mens locker room after a gangbang, or one of his old spank socks.

The smell was so strong, not even her perfume could counteract the fact that she always smelled like a freshly used dick. Freshly made semen drooled from her lips constantly, her shirt and forearms were smeared with drying and caked semen all along her clothes and chin and mouth.

John could barely hold back his laughter, the once high and mighty queen of the school now had her mouth always full of cum. He wondered how the heirarchy would affected now that she was always drooling like a leaking cock. How do the boys react when she wants to kiss, or give a blowjob. How do the girls react with all the semen she's spitting everywhere constantly, when talking, breathing, eating. Could she get a girl pregnant just by eating them out? all these questions made John hard and horny.

"Phreak" She poke with that slurping lisp, trying to swallow back a fresh load of cum back into her own throat. She'd probably eaten hundreds of gallons of cum in her lifetime this far.

John smirked, freak huh?

Zzzzt! Zzzzt!

John gave her another zap from the gun and watched how the clothes she was wearing now looked soggy and drenched, and just as slimey as her mouth. He had changed the content of her sweat glands as well, she now produced semen and cum as sweat. He had also swapped out her mammary glands with that of testicular tissues, also as overproductive as the rest of her semen producing body. He'd changed this voluptuous queen of the school into a walking, talking, spurting ballsack. He could hear her shoes squishing on the carpet, her clothes squelching with every move. Every step was marked by footprint caked in semen, she was a walking cum factory and was none the wiser that she'd ever been anything different.

John followed her to her room, careful to avoid the puddles of cum at her step. Silently he watched as she walked in and began to undress without a care in the world. Did she know he was watching, he didnt know. She just dropped her clothes into a heavy pile, weighed down by what seemed like a gallon of cum each. when she dropped her panties and bra, they looked completely soaked and dripping.

John noticed that floor was black tile, shiny and smooth. There was even a floor drain in the middle with a slant that lead into it. She walked barefoot across the tile, every step permeated with a sloppy splat of cum. Her bed was on the far side, covered in a shiney latex like material. No doubt cum resistant. She stopped at a desk, covered in the same material and sat down, her breasts slapping down upon them heavily. Johns eyes widened as he noticed that her breasts were now as big as his mothers were and perhaps even bigger now, and covered with fleshy yet subtle veins. She groaned, and panted as she massaged them. Using her own bodys copious fluids as lubricant as John saw her breasts literally pulse and grow with her intense massage.

She moaned softly, feeling up her tits and rocking back and forth rhythmically. John could see her breasts practically vibrating when she suddenly looked up and stopped, her hands squeezing her breasts hard as she made eye contact with John at her door. She gasped in shock, but it wasnt verbalized thanks to the giant globs of cum pouring from her lips in her excitement.

She jumped back and scrambled to the door all while never letting go of her breasts, even as they pumped and pulsed wildly. Her nipples were hard and huge, with big wide vibrant red areola that puffed up obscenely, they twitched in the air wildly. Gwen staggered to her door and slammed it shut on Johns face before a gurgled scream rang out and John heard a heavy and long "SPLLAAAAT!" from behind the door along with a river of cum soaking into the carpet underneath her door.

"Phuckeen verpv" She lisped, gasping and moaning and slumped against her door. John smirked and walked away, trying to ignore the smell of drying cum that now seemed to permeate every corner of the house.
