"Damn, Eddie, could you not act like a complete child for just one minute! Jesus, you're so fucking annoying."
Richie was aggravated, Eddie had been whining all day about wanting to go get ice cream, and Richie didn't want to leave the house.
But Eddie didn't take anger well. Tears welled up in his eyes, and he ran to the bathroom. There he curled up on the ground and bawled his eyes out. He hated when Richie was mad at him.
Richie instantly felt regret. He sighed, knocking on the bathroom door.
"Eds? Come on, it's not that big of a deal. I'm sorry, all right? You're just always bugging me and sometimes I get pissed. Don't act like a baby over this."
That's when Eddie got an idea. He'd show Richie what acting like a baby really looked like. He closed his eyes and peed himself, letting the liquid soak him, before fussing and crying.
Richie was confused. He opened the bathro door, revealing Eddie sucking his thumb and wetting himself. The moment he saw Richie, he made grabby hands towards the taller boy.
Richie's eyes widened. He didn't know what was happening, but he picked the small boy up, carrying him into the bedroom and laying him down on the bed.
"Eds, why did you do this?"
"I had an accident, Chee, I can't help it!" Eddie began to cry, squirming around before peeing again, all over Richie's bed.
"Eds, shit, now I have to clean my bed and my bathroom floor!"
"C-change me, pwease?"
"Yeah, yeah, okay, I get it. I'm sorry for calling you a baby. Now be normal again, okay?"
That pissed Eddie off even more. Some people lived like this, and Richie just insulted them. When Richie picked him up, he wet again, crying for a diaper.
"Eddie, the only diapers are my baby sister's princess diapers. I can't steal those from her, and you don't need them!"
"Pwease, Dada!"
That sent Richie over the edge. He went into full dominance mode.
"Okay, baby boy. Daddy's gonna change you, princess."
Eddie tensed up. He wasn't expecting this to happen. But, he relaxed as Richie bounced him on his hip, kissing his forehead and baby talking to him. He felt safe like this, and he decided to continue to act like a baby.
When they reached the changing table, Eddie began to cry. He didn't like the height.
"Ssh, baby boy, it's okay, it's okay." Richie said, taping the diaper onto his baby.
Eddie began to squirm in the diaper, realising he liked the feeling. Maybe Richie getting angry with him wasn't such a bad thing.
"Richie, can I be big for a minute?"
"Of course, Eds, what's up?"
"I, uh, I know I did this because I was mad, but, um, I kinda like it. C-can we do this more?"
Richie's face softened before he nodded, kissing Eddie's head.
"Of course, angel. But we need to set some rules, okay?"
"Wes sir."
"Only call me Dada or Daddy, or sir, sometimes, only potty in the diapers, even if you're a big boy, always drink out of a bottle and only when I decide to feed you, and I will punish you with spankings if you decide to disobey me, okay?"
Eddie nodded.
"Okay, good boy. Your safe word is red, okay, princess?"
"Otay, Dada!"
Eddie squirmed out of Richie's arms and ran down the hallway, giggling adorably.
"Bet you can't catch me, Dada!"
"Oh, I bet I can! I'm going to get you!"
Eddie squealed, running into the living room. He covered his face with his hands and curled up in a ball. Daddy would never be able to find him now.
Richie spotted the small boy right away, but he didn't let him know.
"Hmmmm, where could my boy be? I can't fund him anywhere! Oh well, guess I'll have to find a new baby boy!"
Eddie jumped up in fear.
"No, Dada, I'm right here!"
Richie giggled, picking the baby up.
"Would you weawwy wapwace me, Daddy?"
"Never, baby boy. Never ever."
