Audio RP #135 (LG extended version): Your older sister changes you into your nighttime diaper (ABDL) (Patreon)

Our parents left me in charge of you while they’re away. This audio starts out with me on the phone with my boyfriend, he’s coming over soon. I need to enforce an early bedtime for you so we can have privacy. That means it’s time for a diaper change

In the extended version you start to regress hard and care less about being seen as a baby
