Jacob woke up first, but he shut his eyes, and tried to fall asleep. Then he became aware of an uncomfortable wetness between his legs.
"Damn it," he said in his cute little boy voice. He was still a kid, for at least another day.
"What is it?" asked Greg, sleepily. Both boys were tired, and it took a few seconds before they both realized what was different about Greg's voice.
Jacob sat up in bed, looking at Greg. "Greg, you're a teenager again."
Greg sat up, then threw off the blanket, revealing a fuzzy teen body, much larger than what he'd gone to sleep in. He was still wearing GoodNites between his legs, white and dry. They both looked at Jacob, seeing how damp he was.
Because Greg didn't wet the bed, he had turned back to his normal age, leaving Jacob alone as a 7-year-old.
"Oh this is not fair!" They both said at the same time.
"I know, I want to grow up, this was your idea," Jacob's high pitched voice accused.
"Yeah, and I had way more fun yesterday, so you should be the one changing back." Greg looked at Jacob again, studying his body.
Jacob felt embarrassed to have his friend looking at him like that. It was one thing when they were both 7, but now Jacob felt like he'd started crying in class or something, totally humiliated. Jacob was always the mature one of the two, but even sitting down in bed, he now had to look up at his best friend.
Jacob was grumpy that morning. He took a shower instead of a bath, because he didn't want to have Greg bathe him. He was soaping up his urine soaked little sack when Greg came in the door to the bathroom.
"I won't look," said Greg, "but mom says I can't leave you alone, because she thinks you won't wash properly, so I came in here just to get her off my case."
"Yeah, whatever," said Jacob. He resumed washing.
"I found out that, apparently, they think I'm babysitting you while your parents are away, and last night you slept in my bed because you had a nightmare." Greg couldn't quite keep the amusement out of his voice.
"It's not funny!"
This made Greg laugh harder.
Greg turned away when Jacob got out of the shower, but he surreptitiously peeked at his naked little friend in the mirror, catching more than one glimpse of Jacob's perky little butt.
Jacob played with toys, and Greg joined in. He didn't have as much fun as Jacob, but he was still hanging with a friend, and unlike when playing with a real little kid, Jacob could also have conversations about school, video games, and other stuff that a little kid wouldn't know about.
Greg kept an eye on Jacob's fluid intake. He was jealous that Jacob got to be a little boy for so long, but he knew Jacob wouldn't want to spend more than two days being unable to see over the bathroom sink.
Greg took Jacob to the park. They both rode bikes, and Jacob was actually able to have the training wheels removed from it since he really didn't forget how to ride a bike.
Greg sat on the jungle gym, watching Jacob crawl and climb and swing all over it.
"Look at what I can do! I'm so light!"
Greg smiled but felt a little more resentment. Sure, he could climb more, it just wasn't that fun.
"Hey, that's Greg. Greg!"
Greg turned to see a couple friends from school. "Jacob, it's Mike and Tina."
"Oh, don't tell them it's me." Jacob climbed towards the other side as their friends approached.
Greg talked to them for a while. He explained that he was babysitting his little cousin. He dropped hints about it being just like their friend Jacob, and they didn't know who he was talking about.
"Do you want to come over later? Mom says we can get pizza tonight."
"No thanks," said Greg. "I kind of have to babysit him for like, at least another week."
"Nuh uh," said Jacob. "I bet I'll be back to normal tomorrow!"
"Wow, that kid has a shrill voice," said Mike. "Leave us alone, the big kids are talking."
Jacob's face went red.
Greg couldn't resist. "Guys be nice to him." Then, in a stage whisper, "He's a little grumpy today because he wet the bed last night. Shhh."
Jacob ran off to go hide in the big tube-shaped slide.
* * * * *
Eventually they made their way home for dinner, but Jacob didn't talk much on the way back.
At 7PM, they got ready for bed again. Jacob insisted on sleeping in the guest bedroom. Greg, enjoying the feeling of power this was giving him, followed Jacob in there.
"Make sure you put your GoodNites on. Come on, go ahead."
"Greg, I'm sick of you treating me like a little kid."
Greg chose to ignore this. "I guess I have to put them on you myself." Jacob ran for it, looking for a hiding spot in the room, but Greg snatched him up. Jacob's struggles literally were nothing, his tiny body had no strength to keep Greg away. Greg held Jacob down with one hand easily, while peeling off Jacob's cute little clothing, his socks, his pants, his shirt, and finally, his Paw Patrol briefs.
Jacob ceased struggling. He was naked now, what use was it?
Greg grabbed the GoodNites. He then took Jacob by one ankle, to put one leg of the GoodNites in it, when he noticed something that stopped him in his tracks.
With one ankle pulled away from the other, and with Jacob on his back, between his legs, under his high tight little nut sack, was his butthole, looking tighter and cuter than anything Greg had ever seen.
"Stop looking at my dick," said Jacob, not realizing what Greg was staring at.
"Sorry, it's just... I've never seen a 16-year-old with a half-inch penis before." Greg quicky finished putting the GoodNites on Jacob. After Jacob was tucked in under the covers, Greg said, "You can do it Jacob. And don't think about waterfalls or anything when you're dreaming."
Jacob threw a pillow at him. When he was alone in the dark, with one hand inside his disposable underpants, he wondered how long he'd be stuck as a bedwetting little boy. It was fun, but he didn't want to be trapped like this, alone, while his best friend went to high school and then college.
Greg meanwhile, didn't actually go to bed. It was only 7PM. Instead he stayed up, and thought about Jacob, and how cute he was, and how, maybe, his friend might be stuck that way for a long time. Jacob had been a bedwetter until he was 10, and he might not stop until he was 10 once again. But...he'd need a babysitter in the meantime, right?
