Clarifying context; this is a fantasy world where ageplay is normal. Carter and Joey are trans-masculine.]
Carter was sitting in the backseat happily looking out the window. Car rides were his favorite thing and he’s excited to be going to the beach with his mommy and their friends.
He woke from his nap content and Mommy assured him they’d stop for lunch in about thirty minutes and meet with their friends.
Things were fine until his stomach suddenly contracts and mess squeezes out his bum. Mommy hears her baby grumbling and breathing heavily. She looks into the mirror and at the back seat at his “pooping face.”
He breaks out sniffling and Mommy immediately starts to comfort him.
“Oh baby, it’s okay. That’s why you wear pull ups on road trips.”
“Didn’t know I had to go.”
“We’ll get you cleaned up soon, I promise.”
A bit later, they pull into the restaurant’s parking lot. Mommy grabs the diaper bag from the trunk before unbuckling Carter. They meet up with their friends and the group heads into the restaurant.
“Hey Sara, hey buddy!” Daniel waves
“Hey Joey.” Carter waves back
“Hey Dan. How was the drive?” Sara asks
“Pretty good, he slept through most of it.” Dan nods
“He needs a fresh diaper.” Dan whispers
“Carter too. Want me to take them once we get a table?” Sara whispers
The waiter calls them over to a table. Dan orders everyone’s drinks. Once the waiter leaves he hands Sara Joey’s diaper bag. Mommy, Carter, and Joey head to the bathroom for a change. Mommy puts the diaper bags on the changing table. “Come on bud, you gotta go first, that’s a stinky pull-up.” Carter blushes but comes over to his mommy. She lifts him onto the changing table and pulls off his pants.
She gently starts to wipe the mess off his bum and cunt. Carter squirms at the cold wipe. Joey watches intently.
“Carter's stiffy!” Joey shouts
“Shut up Joey!” Carter yells
“Aye, be nice.” Mommy scolds
“Come on, your turn.” Mommy puts Joey on the changing table and starts to undress him. She gently untapes his diaper and gets out a pull-up from the bag. Carter peeks at his pussy. It's a bit damp from his accident and his t-dick is a bit hard.
“You’re stiffy too.” Carter points
“No, I’m not!” Joey blushes
“God, you boys.” Mommy chuckles, “Why are you stiffy? Is it hot seeing each other’s butts?”
Both boys stare at the wall with bright red faces. Mommy laughs and finishes cleaning Joey up. “Pull your pants up” She places him on the floor.
The boys quietly return to the table with their blushy faces. The two caregivers quickly exchange looks. Maybe there’s something there. Or perhaps they just like their diapers a little too much.
