“Enjoy your ride,” the attendant said as Mia walked into the space of the ride. None of her friends wanted to join her on the teacups, they said they were all too old, but what did they know? Mia loved the teacups. Besides, how many times do you go to Disneyland? Might as well do everything you can. So Mia clambered into the teacup cart, accepting that she’d have to do all the spinning herself. She closed the door and gripped the center disc, ready for the ride to get going. Feeling the ride start to move, Mia began turning her teacup. She loved the feeling of the force pushing her towards the wall of the teacup, loved feeling dizzy as she spun around and around.

There was magic swirling in the teacup with her, but she didn’t notice anything different than usual, attributing any feelings to the forces pushing her against the wall of the cup. Soon after the ride started, the magic took a hold of her, and started its work on her body. Mia’s small breasts pushed out against the bandeau bra underneath her t shirt. They slowly grew, the acceleration from the ride keeping Mia flat chested-looking. As the ride spun, Mia grew bustier, and her bandeau began to slip off her increasingly large bust. She didn’t notice, still focusing on spinning her teacup. As Mia’s breasts grew to softball size, her bandeau fell off completely, her bigger breasts now free to expand within her shirt. Her tits started to bump into her arms more often as Mia turned the disc, but she ignored the feeling of her arms pushing into her boobs.

Mia unconsciously adjusted her arms slightly with every spin, raising them up higher and higher to avoid her breasts. Finally, they grew tired, and Mia released the disc and let the forces push her against the wall. Her arms spread horizontally from her.  She looked down, and was vaguely aware that her small chest was no longer very small, the tits rising from her chest now more akin to melons. I must be getting really into this ride, she thought. Now I’m hallucinating. Mia slowly moved her hands against the centripetal force towards her chest. Once she got her arms perpendicular to the walls, the force pushed her down, her hands smacking into her boobs. Ow! She thought. Then, a moment later, Holy shit! That is all me!

Shocked, Mia groped herself, confident no one could see her as the ride spun. I’m huge! What happened? Mia would swear she could feel her boobs plumping up, growing against her hands. I’m still getting bigger… when will they stop? Her pink t shirt was stretched as she grew, her tits swelling to huge sizes. Luckily it was huge on Mia’s body, a few sizes bigger than she would normally wear. However, the forces acting on her pushed the shirt against her body, highlighting her top-heavy—and getting heavier—figure.

Mia let her arms go back to resting against the walls, accepting her continuing breast growth. There was nothing she could do about it for now, anyway; she might as well enjoy it. Her only concern was that, as her breasts grew bigger and bigger, there was more weight pushing against her torso, against her lungs. Her growing tits were making it harder to breathe. Slowly, delicately, Mia tried to slide her way out from under her boobs, trying to get them to rest on the wall as she sat sideways. With some difficulty, Mia unwedged herself from under the increasing weight of her chest. Her boobs smushed against the side of the teacup, her one arm resting on top of the swelling masses.

After what seemed like a time longer than the ride should have gone on for, Mia felt the teacup she rode begin to slow down, her boobs pushing less into the walls, obeying gravity more. Her cup came to a stop near the exit, and Mia slowly stood up, adjusting to her dizziness, not to mention the two huge breasts she now carried. She wobbled to the exit, tiny hands pressing into the bottoms of her figure-dominating tits as she walked, trying to keep the weight from pulling her forward onto her face. Mia tried her best to ignore the stares. The most magical place on earth, she thought.
