One day after Pampaku came home from teasing Bowser with massive poofy pamps, he brought back some power ups for use and experimentation. The one that caught his eye was the P Balloon, which makes anyone bwoomp up when used, so Pampaku had the idea of turning it into a plump poofy diaper. After he did so, Sophie came in to check on her beeg bro, and so seeing his opportunity, Pampaku gave the P Balloon pamp to his tiny bun sis. Sophie thanked him for the pamp and went to her room to try it on, with Pampaku close behind her. Once the diaper was on her waist, Sophie felt a strange sensation in her belly, then all of the sudden the Diaper wrapped around her body, making her rapidly bwoomp up shortly after. Following up on being bwoomped, the diaper smooshed the ballooned Sophie until she gave in and started loading her diaper with massive loads of floof poopies. Both Pampaku and Sophie were surprised that she was still floating even though her massive doughy loads should’ve weighed her down, even as she keeps filling her bwoompy diaper butt. After, Pampaku gave Sophie some loving Diaper smooshies himself, with Sophie letting herself floof poop her diaper more, soon to become a massive doughy diaper balloon bunny.
