He puts a pull up on

Ryan went to the bathroom once his mom left and he carefully fetched his hidden stash of pull ups. They were dinosaur pull ups meant for their younger cousin, but Ryan fit into them. He sprinkled a little bit of baby powder on his balls to reduce the chafing as he slipped into the pull ups. He put on his pajamas over them and slipped into the sheets.

Under his sheets in his diaper, he felt like a little boy. He closed his eyes and fell asleep.
