Recently, you had pulled a prank on your older sister Kagami by stealing her sweets and leaving the wrappers in her room, leaving her frustrated. However, she had an evil plan to get back at you. Your mother had a strange method of punishing you, being to diaper you and get you to use it to humiliate yourself. Your mother was out this morning though, so Kagami was in charge. An hour before, she left your hand in a bowl of warm water, causing you to wet your diaper. After you woke up, you became red due to your embarrassment over the fact you basically wet the bed, but Kagami walked in with a smirk.

'Aww, is the baby wet? Don't worry, big sis will get that sorted out for you.'
