Jessica

Peter looked up. Jessica was watching him with an evil smile.

Feeling a wave of unease, Peter asked unhappily, "Where's my mom?"

Jessica laughed. "Well, I see you've fully embraced your role, you worthless man," she said, pinching his cheek.

Peter felt a wave of weakness. It had been a month since that family picnic, and in all that time, Jessica had almost never come to her mother's house, but now...

"Mom had some work," Jessica explained. "She told me to come and take care of you until Nicole gets back."

Peter's face fell. He knew Nicole was at work until 6 PM and wouldn't be home before 6:30 PM, even if she left early. This meant Elizabeth didn't intend to return until then. Peter would have to be alone in the house with Jessica until Nicole returned.

All these thoughts broke his concentration, and he lost control of his bladder, wetting his diaper, which was already full of poop and pee.

Wearing a diaper and childish clothes, Peter was on all fours in front of his sister-in-law, Jessica. As he was peeing, Jessica noticed from the look on his face and burst into loud, mocking laughter.

She bent down, picked him up, and held him in her arms. Now Peter was in Jessica's embrace, and it was a terrible day.

Jessica: "You know I hate you. I've always thought you were a worthless man, but now that you've accepted your mother-in-law to diaper you and treat you like a baby, my opinion has changed. I think you're a pathetic person."

Jessica's words brought tears to Peter's eyes.

Carrying Peter, Jessica entered the room and laid him down on the bed. She undressed him and then opened his diaper. Peter's diaper was completely soiled and full.

Jessica laughed at him again. "It's truly beautiful, isn't it? To see my proud sister's husband has completely messed himself and is now dependent on me like a baby to clean him up."
