-Aliza is always trying new things in her training. After talking to some crew members she decides to try some different supplements and a new training routine.

-she feels amazing the morning after her next workout, decides to take the new supplement with every workout and stick with this new routine.

-her workout pants slowly become workout shorts as she gradually grows taller and taller while maintaining her shortstack proportions. Her whole body feels lighter and stronger but her tits feel heavier, just what the hell is going on? But she's been getting so much stronger, it wouldn't make sense to change her routine. She must be getting more flexible, too; she can even reach some of the equipment at the gym more easily.

-the realization that she's gaining *size*, not weight, unexpectedly turns her on and after an intense masturbation session in her too-small clothes she resolves to start training even harder since that seems to be what's making her grow. She's getting stronger and more toned while also growing taller. Because she's gaining both size and strength her lifts skyrocket; before long she's warming up with other trainees PBs. She begs Gran to order custom made equipment so that she can continue pushing her limits.

-She proudly wears the training clothes she's slowly outgrowing, loving the feeling of the light, airy fabric stretched to its limits across her expanding curves. Her libido and appetite both grow with the rest of her; she used to pleasure herself infrequently but now she's masturbating after every single training session. The bigger she gets the better it feels.

-She finally outgrows her old training clothes, busting out of them in the middle of a training session. This turns her on so much that she masturbates in the middle of the gym before finishing her workout nude.

-after a few months she figures out that it's the supplement shake, not her training, that's causing her to grow; she's become addicted to getting bigger and decides to down as much of it as she can stomach in one go

-she lays on her bed and masturbates furiously as she outgrows it, eventually rolling onto the floor as she grows out of her clothes, her fingers never leaving her pussy. The story ends with her feeling her new body up and down and basking in the afterglow
