“Come on Rosey,” Michael said in a sweet voice shaking a rattle at the pouting dog. “Don’t you wanna play a little bit?”

“No!” Rosey said flatly. He grabbed the rattle and threw it across the room. “I don’t want to play baby games. Do I look like a baby to you?”

“Uhhhhh,” Michael was not sure the best response to that question. Rosey did look like a baby, but Michael doubted that’s what he wanted to hear right now.

“Yeah! So just leave me alone!” Rosie finished as he pouted off. “Stupid cat,” he said under his breath as he walked away.

Topsy was watching nearby and she buried her head in her hands.

“The way he’s acting one might think he doesn’t like this,” Butch, who was watching the scene unfold with Topsy, added. “He does like this right?”

“Well, it wasn’t exactly his choice to be an adult baby,” Topsy explained. “But Haruhi said he enjoys it.”

“He might enjoy it with his mommy, but his babysitters are clearly a different story.” Butch left to go see if Michael was ok.

Topsy fell to the ground and curled into a ball by the wall. This was not going well. When she offered for the alley cats to baby sit Rosey, she thought it would bring them closer together. She thought that this challenge might bring back the spark that their relationship had lost over the years. So far, it had only caused them grief and split them even further apart. She could tell that Butch and Michael both blamed her for this blunder.

Topsy raised her head from her knees with a new determination. This whole idea was a failure, Topsy resolved to at least make this as little a failure as possible. It was clear that Butch and Michael at this point wanted nothing to do with their temporary charge. If it meant they would feel better about the whole thing, Topsy was happy to take on the burden by herself. It wasn’t going to be the fun time she originally imagined when she agreed to babysit for her friend Haruhi, but it was the best way to salvage this disaster.

“Rosey,” Topsy said nervously approaching the dog.

“What do you want?” Rosey answered spitefully. “Why do you keep trying to baby me? It’s not gonna work.”

“It’s not working because you’re being difficult,” Topsy shot back pouting herself. “Why are you being so difficult about this? Your mommy just wanted to make sure you stayed as a baby.”

“Yeah, and I wanted to be a big ki … an adult. I still can be you know, and I don’t appreciate having the rug pulled out from under me. Especially if it means I’m stuck being baby to a bunch of cats.” Topsy frowned at the comment.

“Rosey you’ve been a baby for years now, do you really think you can just go back to being an adult?”

“I can adult just fine!” Rosey said offended. Topsy gave him a look of disbelief. “If I’m such a baby, I guess you gotta change my diaper then,” Rosey said suddenly changing his tone.

“Really? You’re wet?” Topsy clearly didn’t believe Rosey so she knelt down and began unsnapping Rosey’s shortalls, which had snaps at the bottom for diaper checks like this. “Rosey this is barely wet. You do not need a change.” Topsy started to snap the shortalls closed again but Rosey stopped her.

“I guess if you won’t change me, I can go ask Michael,” Topsy could feel Rosey’s smirk even though she wasn’t looking directly at his face.

“You will not be bothering Michael or Butch again. Do you understand?” Topsy said in her best threatening top voice.

“Then I guess you better change my diaper then.” Rosey and Topsy shot each other challenging looks for a few moments.

“Fine,” Topsy relented with a sigh. “Lay down on the bed, I’ll be with you in a moment.”

“That’s what I thought,” Rosey said smugly. “You know, you can make this whole thing a lot easier for both of us if you just let me be big like I was promised.”

“I can’t do that,” Topsy said in exasperation. “I told Haruhi I would …”

“Well then this is going to be really difficult for you,” Rosey cut Topsy off. Topsy let the comment slide with a huff as she trudged over to the pack of diapers that was sitting next to Rosey’s other bags.

As Topsy grabbed a diaper in her hand, she sighed in defeat. Was it really worth it to keep going? Rosey was intent on giving the alley cats a hard time, and that would only make this situation worse. Maybe it was better to just give in and let the dog be an adult for the week. She would get an earful from Haruhi when she got back, but that was surely better than the damage this was doing to the alley cats' relationship. She was just about to put the diaper back in its bag, and let Rosey have the adult week he wanted, when she was stopped by Butch gently grabbing her wrist.

“What Butch?” Topsy said angrily. “I’ve got it taken care of ok. I’ll handle Rosey, you and Michael don’t have to.”

“Just …” Butch’s tone was different. Toward Topsy it was caring, but Topsy could feel a darkness directed at Rosey. Topsy immediately went into a submissive mode at the change in his voice. She knew the tone well. It was the tone Butch took when he was about to deal out some real discipline, not just something for fun. She rarely heard it herself and knew how serious it was. “Wait here for a second.”

“Yes sir,” Topsy obeyed automatically. She sat by Rosey’s diaper bag as she watched Butch approach the dog.

“Where’s the white one?” Rosey asked in a mocking tone as Butch approached him. “I thought I was getting a diaper change.”

“Oh, you are,” Butch forced Rosey to lay down on the bed in the room, and quickly fully unsnapped the shortalls fully, folding them over Rosey’s chest. “There may be a brief interruption in that though,” Butch said as he almost ripped off the barely wet diaper. “I think someone is in need of an attitude adjustment. A reminder about what your place here is. A reminder about respect.” Butch punctuated this little speech with a hard smack on Rosey’s bare bottom.

“Owwwuh!” Rosey yelped at the pain. “What are you doing. Owooooah!” Rosey screamed more. It was all he could do as Butch got to work spanking Rosey relentlessly. "Ooo! Ooo! Ahh! Owahah!" Rosey screamed in pain as he was spanked.

“Topsy is just trying her best, and you are not going to give her a hard time. Do you hear me?” Butch said while continuing to spank Rosey’s bottom.

“Nooo! Owww! Butch!” Rosey yelled.

“No? No, you don’t understand?”

“No Butch I’m gonna. I’m gonna. Ahhhhh!” Rosey let out an all together different cry that caused the room to pause. Butch rolled the dog over onto his back. Rosey blushed a deep red as the evidence of what just happened was impossible to ignore. His hard cock was covered in fresh cum. Butch grinned as he put two and two together.

“So, you do like being a baby,” Butch said full of irony. "Or at least getting spanked when you're being bad." Rosey stammered in embarrassment, but didn’t get a chance to respond as Butch got back to work spanking. It didn’t take much longer for Rosey to be left crying like the baby he looked like. “So, are you going to continue being a problem?” Butch said while smacking Rosey’s thigh. “Or are you gonna be a good little baby for your auntie and uncles?”

“I’ll be good,” Rosey said defeated. “I’ll be a good little baby for auntie and uncles,” Rosey added after a look from Butch.

“There we go,” Butch smiled triumphantly.

“Aww you’ve scared the poor thing half to death,” Michael said stepping back into the room to coo over the fussing Rosey.

“Oh, that wasn’t fear,” Butch smirked.

“Either way the baby needs to get cleaned up and changed,” Michel walked by Topsy to grab a diaper and winked at her.

Topsy's mood improved, and she began to smile as she saw Michael cooed and fussed over Rosey during his diaper change.

“Thanks Butch,” Topsy said as Butch started to leave the room.

“Don’t mention it," Butch smiled playfully. "Nobody messes with my girlfriend. Plus, it was nice to give out a real spanking you know?”

“Not really,” Topsy admitted. “But I’m glad you had fun.”

“Yeah, I guess I did,” Butch said thoughtfully.

“Ok Topsy I think our little one is in a much better mood,” Michael helped the now much quieter baby Rosey sit on the floor next to Topsy. Rosey had been changed into a blue footed sleeper decorated with a bird on one of the breasts. Rosey looked away from Topsy with a blush and he suckled the pacifier that was clipped to his sleeper.

“I’m uhh, I’m sorry Auntie Topsy,” Rosey said looking at the ground in shame

“He certainly is in a better mood,” Topsy agreed with her partner. “So little one, how do you feel about playing blocks with your babysitter?” Rosey looked to Michael's gentle encouraging smile as well as to Butch’s subtle threatening frown.

“Bocks aunnie,” he said over his pacifier.

*****

It had been a tough week for Haruhi. Her conference was so full of work that she almost forgot about her baby Rosey and where she left him. Standing in front of the alley cats’ door, Haruhi’s anxiety about the whole thing flooded back into her. She dreaded what might await her on the other side of the door as she knocked. She was surprised when Topsy opened the door with a smile. A quick glance inside the house immediately assuaged all of Haruhi’s anxiety. Inside she found Rosey happily bouncing on Butch’s knee as Butch cooed over him.

“Aww that’s a good baby,” Butch said happily as Rosey smiled in response. The scene stopped when everyone noticed Haruhi was at the door.

“Mommy!” Rosey said happily, causing Butch to grunt in pain as he haplessly bounded from his lap.

“Easy kiddo,” Michael said gently as he entered the room. Rosey had already made it to Haruhi and was hugging her tightly.

“I see you had a good time,” Haruhi said with relief.

“Only a little hiccup at the beginning,” Topsy explained. “Otherwise, he’s been an angel.”

“Well, that's good to hear,” Haruhi said letting out a breath of relief. “I appreciate it. You guys, you really helped me out.”

“Any time.”

"Yeah," Michael added. "We'd love to have him over again."

"It was a lot of fun." Butch added. Haruhi smiled.

“Ok sweetie let’s get you home,” Haruhi knelt down and fastened a harness to Rosey.

“Bye!” Rosey waved to the Alley Cats as Haruhi finished fastening a harness and leash to Rosey. Haruhi also waved bye to the alley cats as she dragged Rosey away to the waiting car. With a happy smile, Topsy gently closed the door and turned to her partners.

“Well?” Topsy asked Michael and Butch hopefully.

“I gotta admit it, it did grow on me,” Michael said snickering.

“Yeah, getting someone to fully go into being a baby like that …” Butch had to stop himself short. “I liked it.”

“So, we gettin’ a baby of our own?” Topsy asked smirking.

“I wouldn’t mind,” Butch said shrugging.

“Trouble would be finding someone we can make a baby,” Michael added.

“Oh, I think I know just the cat,” Topsy replied knowingly.
