I put the nappy pants-style diaper on, and the sweet voice helps me with getting the diaper on myself. Suddenly, I get a slightly warm feeling inside my body, and slowly, I start to shrink...

I see the room around me getting progressively larger, while my diapered behind is looking more and more like that of an Elementary School-aged kid. Finally, I feel myself entering a state of that more akin to a preschooler. The nappy pants gets more crinkly, while my fur starts to feel more soft and is also getting shorter. I flop onto my little belly just as the regression is about to come to a close. Finally, the regression effect wears off, and I have become a cub. I am balancing between the ages of a preschooler and a toddler. I am now just barely four years old!
