Suddenly, Casey felt his body begin to ache. "Ouch!" he yelped as he fell down.
"What's wrong?" Kelly asked as she rushed over to help him.
"My body hurts. It feels like I'm getting sick," Casey explained.
Kelly noticed that Casey was starting to look smaller and that his muscles were losing their definition. "It looks like you're changing into a Joey again," she remarked.
"Huh? But, I don't want to be a kid again!" Casey insisted.
"I know, but it looks like you don't have a choice," Kelly said sympathetically.
Casey's transformation continued until he was a young Joey again. He looked up at Kelly and sighed. "Now what are we going to do?" he asked.
"We'll figure it out. I'll take care of you," Kelly promised as she picked him up and placed him in her pouch.
"Thanks, Kelly," Casey said as he nuzzled her fur.
Just like before, Casey couldn't help but suckle Kelly's breasts for sustenance. At first, Kelly was embarrassed, but she quickly got used to it and found herself enjoying the sensation as she bounced through the grass. In a strange sense, Kelly was happy to be taking care of Casey like this. Even though their relationship had changed, she still wanted to protect and provide for him.
Eventually, Kelly spotted an open doorway that led into a tunnel. She knew she needed to get Casey somewhere safe and figured this might be a good place. "I think I see a way out of here," she announced as she started to move towards it.
