Use the diaper.

You're afraid to stand up because Brad might be able to tell there's a diaper under your pants. You realise that you don't need to get up. You are wearing a diaper. You might as well use it.

You release your bladder and feel the diaper flood. You panic for a moment, worried that it's going to leak but the padding does its job and absorbs the liquid, growing thicker as it does.

You're filled with conflicting feelings. It's embarrassing to wet yourself but exciting to do it without anyone knowing. You feel small and **** but also protected.

"You okay?" Sarah asks, noticing something different about you.

"Yeah." You say. "Sorry. I was just thinking about something."

"Did you just wet your diaper?" She whispers?

You blush, realising you weren't as sneaky as you thought and answer with a nod.

She smiles and hugs you tighter.

Eventually, Brad stands up and yawns. "I'm going to bed."

"I'll join you in a minute." Tanya says as he leaves. She turns to you and Sarah and asks. "Do you need a diaper change before bed?"

"Yes." Sarah says. "And Daniel does too."

You look back at Brad, hoping he was too far away to hear that. He doesn't react so maybe you were lucky.

"Okay." Tanya stands up. "Come on."

"Wait." you say. "You're going to change us?"

"I always change Sarah." She explains. "I don't mind changing you too."
