It was a hot day so Jon was perfectly comfortable wearing just his swimsuit. Karyn was wearing a pair of shorts and a t shirt. It was obvious to Jon that she wasn't wearing a bra but nobody else seemed to notice her boobs bouncing around unsupported. As they left the building Karyn held Jon's hand tight, being very protective of him. The bus stop was at the end of the block and she led the way.
When they got on the bus Karyn took a seat and sat Jon on her lap. She didn't show any signs of discomfort to have this teenage boy who was normally much heavier than her sitting on her lap. Jon took some time to look around the bus. Most of the other passengers weren't paying him any attention. He made eye contact with a teenage girl. He thought she was cute and he could tell she found him cute but not in the way he would have wanted. Her face lit up when she saw the cute baby girl dressed only in a cute one piece swimsuit and she smiled at Jon. Jon smiled back. In his old life he would have been over the moon to be noticed by a pretty girl like that. He liked to think he'd have worked up the courage to talk to her but, right now, she wouldn't even understand him if he tried.
A short bus ride later and Karyn picked Jon up and got off the bus. They made their way into the gym and Karyn carried Jon into the men's changing room. She found an empty locker and stuffed her bag inside. She took off her shorts and Jon saw that she was wearing togs underneath. Next she pulled off her t shirt, freeing her breasts but not showing any sign of caring. Nobody else seemed to care either.
Karyn lead Jon out to the pool and headed for the shallow end. She told him to "be a good girl" and stand by the side of the pool while she got in. When Karyn was in she stuck her arms out towards Jon and encouraged him to get in with her. Jon wasn't nervous, he was actually a pretty confident swimmer. He sat on the side of the pool and dipped his legs in before taking the plunge but going slightly away from Karyn as he didn't feel he needed her help. Jon started to move his arms and legs like he remembered but for some reason he didn't get the same power in his movements. He just splashed around a bit in the one place and then slowly started to sink a little bit. Before Jon could panic Karyn was by his side and had taken both his hands and was keeping him afloat. Jon tried to kick his legs with all his might but all he achieved was a bit of a splash and no actual movement. Karyn was encouraging him, saying things like, "that it... Such a big girl... You're doing great sweetheart... Don't worry. Daddy's got you." Jon once again felt glad to have Karyn here to take care of him. The two continued to splash about. Karyn didn't get a chance to properly swim, her entire focus being on Jon.
Eventually Jon got a bit bored and Karyn read his mood and decided that was enough. She made her way to the side and easily lifted Jon out of the water and sat him on the edge again. She easily pulled herself out and then brought ajon back to get dried off and dressed. As they were walking back Jon felt his diaper growing wrt and warm around him and knew that he must be peeing in it again. He didn't really notice any change in how his bladder felt but he could tell that's what was happening.
Once back in the changing room Karyn helped Jon remove his swimsuit and dried him off. Then she focused on herself for a while, leaving Jon standing there wearing only his swimming diaper. Jon looked around and saw a few boys his own age but of course they were wearing normal clothes while he was stuck wearing a diaper. He was glad that they didn't pay any attention to him. Once Karyn had dressed herself she grabbed a clean diaper and lead Jon over to a changing table in the corner. She lifted Jon and lay him down on his back and removed his wet swimming diaper. Now Jon was completely exposed to the room but all the other people had the decency not to look at him at all. Karyn got him into a clean diaper and then soon got him dressed in a t shirt with a unicorn on it and a pair of shorts. The shorts had an elastic band. They were styled to look like regular shorts with a flap of material where the fly would normally but when Jon felt around them he felt that there was no opening. "And why would there be?" he thought, "its not like I'm expected to use the toilet." Jon noticed the shorts were quite tight and actually highlighted the padding of the diaper he wore underneath.
