Karyn felt somewhat flattered to be able to elicit such a reaction from Jon. Jon was a bit annoyed that he had finished so early and he felt bad for Karyn. As soon as he had orgasmed his lust had died down. He stayed leaning over Karyn for a minute and then sheepishly apologised to her for not giving her much pleasure in return.
Karyn reassured him it was OK. With a wink she told him she'd give him another chance to make it up to her later. Jon's diaper was starting to become a little bit uncomfortable and sticky now so he said he needed to change it again before dinner.
Karyn wanted to see how far these changes to Jon went so she decided to offer to change him to see how he'd react. Jon didn't think anything odd about it. He was able to do it himself but was just as happy for someone else to change him. He just handed Karyn the pack of wipes and a fresh diaper and lay back on the bed. He didn't care that Karyn would be seeing him in such a vulnerable, exposed position. Karyn wasn't entirely sure how she felt about the situation but decided to just go with it. She leaned over Jon and undid the velcro straps at the side of his diaper. She peeled the diaper off, glad that she didn't have to deal with any poop. Taking the wipes she started to wipe Jon's penis. He flinched a little bit as the wipes were cold. Karyn was very thorough and Jon was starting to enjoy it. She found some creme on his dresser and rubbed a little bit of around his crotch before getting Jon to lift his butt so she could replace the diaper with a clean one. She closed it up and gave Jon a little pat to indicate she was all done. Jon stood up off the bed and thanked Karyn.
They heard Jon's mom shout up that dinner was ready. Jon grabbed his jeans and pulled them up and over his diaper. This caused quite a bulge to form around his butt and in the front but it felt normal to Jon. Jon told Karyn to come downstairs with him for dinner.
Karyn studied Jon's walk as he went down the stairs in front of her. He was walking with his legs a bit further apart than usual and the bulge of his diaper was very obvious.
When they got in to the kitchen Jon's mom smiled at them both and asked Jon if his diaper needed to be changed before dinner. Jon told her that Karyn had just changed it for him, leaving out the part about what they had been doing to cause it to get messy. Jon mom just smiled and thanked Karyn. She also saw nothing wrong with Karyn stripping her son down and changing his diaper for him. Jon and Karyn took their seats at the table as Jon's sister Zoe and younger brother Mikey joined them.
They all eagerly tucked into the dinner Jon's mom served up. Karyn was delighted. Jon's mom was a very good cook. The conversation was light, each child being asked about school by their Mom. Karyn was listening keenly for any indication of how Jon's changes were perceived by his family. Jon mentioned peeing in his diaper during PE and having to excuse himself to change it but nobody treated this as particularly interesting news.
After dinner, Jon's mom politely told Karyn that she better be getting home as it was a school day. Karyn felt the device in her pocket and decided to leave Jon as he was for now to see how long it would take him to notice, if he ever did. She thanked Jon's mlm for dinner and told Jon she'd see him at school in the morning.
