Audio RP #136 (LB short version): Changed into a diaper by your girlfriend on a road trip (Patreon)

We are on a long road trip and you insisted on driving and not wearing a diaper. Big mistake. We pull over so you can go potty but you can’t pull down your pants in time. This reinforces the fact that you need diapers. I get you changed and insist on driving. In the extended version I nurse you so your tummy is nice and full before I put you in your car seat
