Tell her you're not in the mood.

"I'm not in the mood." You say. "Let's just get this over with."

As you watch Amanda fold the diaper, knowing that she'll soon be pinning you into it, you quickly lose your arousal.

"Up you get." She says, patting the diaper.

You climb up on the changing table and lay back with your bottom on the thick padding. Pulling it up firmly between your legs, she pins it in place. Amanda picks up the plastic pants and guides your feet through the holes. Pulling them up your legs, she stretches them over your diaper.

As you climb down from the changing table, she collects the t-shirt. Pulling it on over your head, she comments "You do look pretty cute in this."

You can only glare at her.

"We should go find Mom." She starts for the door.
