Diapered for Bed

"Now that little Arnie has had his bath," Vernonia said in a sly voice that had Arnold worried, "I think it's time to get him ready for bed." She winked at her brother. "As per mother's orders."

Arnold curled up in the bath, pulling his knees to his chest. "No! Ronnie, come on," he hissed, "that's-"

"Too far!" Veronica laughed. "Come on, Arnold! Melanie has already seen your itty-bitty peepee. She's not going to think any less of you if she sees you getting ready for bed. That's simply not possible."

"What's the big deal," Melanie asked. She giggled. "Does he have embarrassing pyjamas? Do they have, like, Snoopy on them or something?"

"He wishes!" Veronica said loudly. She looked at her little brother, snivelling in the bathtub.

Arnold jumped out of the bath, his hand cupped over his crotch as he ran for the door. Veronica just grabbed his shoulder and yanked him back before he could reach the door.

"Now then, don't be a bad boy or Mom will spank you again," Veronica said chuckling.

"He still gets spanked?!" Melanie asked, amazed. She grinned, as if Arnold's humiliation was her most wanted Christmas present.

"Yep!" Veronica said. "But only if he wets his bed."

"What?!"

Arnold squeezed his cock, keeping it covered easily in his small hand. He bowed his head as Veronica opened the cabinet and pulled out the oversized changing mat.

"Arnie has to wear his diapers to bed," Veronica explained, "otherwise he'll wake up with wet sheets like a baby!"

"I-I don't!" Arnold tried desperately. He knew it was pointless. Especially when Veronica pulled out a package of thick, fluffy diapers, decorated with cartoon frogs.

The package had a large label with colourful airplanes framing the words: 'ARNOLD'S DIAPERS.'

"Now come on, little brother," Veronica, slapped his hands covering his crotch, "lie down and get diapered like a good baby. Otherwise I'll ask mommy if we can give you a spanking- maybe she'll let Melanie give you your spanking. You'd probably like that."

Veronica grabbed Arnold's squirming hands, twisting them behind his back to expose his cock to Melanie. She giggled, covering her mouth as she wriggled her pinkie at him. Arnold just sniffed helplessly. The cooling water from the bath had shrivelled his already small penis to almost nothing. It twitched, barely half an inch long, shivering in the bathroom as water droplets ran down Arnold's chest and his hips before dripping off the head of his tiny penis.

"Aw!" Melanie cooed. "God, I swear my clit is bigger."

Arnold sobbed louder, closing his eyes. He didn't know what to do. His humiliation fantasy had already been a fantasy! He wanted to fight or run again, yet he found himself routed in the spot. It was taking every ounce of his self control not to get hard again!

Veronica whispered in his ear: "Well, baby brother. What will it be?"
