“Ready for Round 2 already Jeff?”
Jeff, her brother turned dick, didn’t respond to Roxanne’s question but she was sure he was on board for more lewd actions. She slowly felt up her erect cock as she thought of her next action. Then the glowing screen of the Chronivac caught her eye, just waiting for her input.
“Oh, that's a good idea! You don’t mind if I play with your Chronivac, right brother?”
Her cock only throbbed in her hand.
“Great! You should let me use your stuff more often.”
Roxanne moved from Jeff’s bed to the Chronivac and pondered her options for change. She could make her cock bigger, make her boobs larger, or make her butt bubblier. She eagerly jerked her 9 inches of sausage, maybe she was thinking too small. There were options for awareness and reality changes, which she found interesting. She could make it so her brother never existed and keep her brother as her penis with none the wiser. She could also change it so that only she was unaware of Jeff’s perverted transformation, oh goodness the thought of that made her hot.
Roxanne grew more absorbed into her rhythmic fapping. Ah fuck it, she couldn’t think right now, and she just wanted to get off again. With a few clicks, she made changes on the Chronivac and waited for the changes to happen. Immediately she felt her cock shrink in her hand until she could grasp it fully. Yup, she shrunk Jeff. From her original 9 inches, her cock was now 5 inches making it a lot shorter and thinner. Then her balls plumped up to be a bit bigger making them enormous compared to natural testicles.
“How you like it Jeff, almost the same size as your old one, only a bit bigger.”
She had chosen to make Jeff smaller to make it easier to jerk her whole length with one hand and minimal effort. Plus, it would humble Jeff for a short while, temper his size envy. She could feel Jeff throb, but was it in protest or arousal? Didn’t matter, she was going to have fun regardless of her brother’s feelings.
Sitting back in her older brother’s gamer chair, Roxanne enjoyed the pleasure of masturbation, spreading her legs wide for her massive balls. Now that she had an average-sized dick she could focus on how amazingly sensitive her foreskin was. She squeezed and pulled her elastic organ with glee in addition to her up and down motion. Soon her entire hand and cock were wet with slick pre-cum.
Eager to experience her mind-blasting orgasm once again she sped up her one-handed fap into a frenzy. She used her other arm to brace herself on the gaming chair’s armrest as she leaned further back, head tilted up in bliss. She felt the heat and pressure center deep in her grip and groin, and it felt good. Her legs tensed as she got closer and closer to orgasm. The pressure then reached its peak and then she froze as the feeling of cumming commenced.
Creamy baby batter surged from her larger than average balls to her throbbing shaft. She practically lifted herself out of her seat as the first arc of gooey white yogurt blasted up and out like a rainbow onto the wall above the Chronivac. Then she went mad jerking at a rapid pace milking her cock for its salty white oil. Jizz flew everywhere, coating the ceiling, wall, floor, Roxanne, and the Chronivac.
Just as she intended, her ginormous balls had produced a ton more liquid fun for her to enjoy. Ejaculation was amazing! After a very long very joyous minute or two of emptying her balls, the pulsing arcs of goo slowed to dripping. Her abused cock grew soft as the blood left it to rest. Sitting in the middle of the white-coated room, Roxanne felt at peace. Forgetting the world for a moment, she felt transformed and transcendent before the fire of lust in her body brought her back to earth.
She was growing erect for the third time since her perverted brother turned into her cock. Was she really in control or was she controlled by her cock? The thought was lost as she readied herself for more sexy times, with a smile.
