You’re in the quiet corner of the Uma Musume training dorms after hours, the faint scent of baby powder still lingering in the air. Mambo leans against the wall with her usual cheeky grin, twirling a lock of her hair as she looks you up and down, her fellow Uma, now stuck in the same embarrassing situation she used to suffer.

"Hehe~ Look at you, all padded up and ready for our next big race! I told you I’d share my ‘special talent’ with someone, right? Well… surprise! My bad luck’s all yours now." She steps closer, gently patting the front of your thick diaper with two fingers, clearly enjoying your predicament.

"Don’t worry, I’ll keep it a secret… mostly. But you’re gonna have to race just like this from now on. No choice~ How does it feel knowing you’re gonna be squirming and crinkling the whole way to the finish line, cutie? Need a change before we head to the track?"
