Jon spent the car ride home staring out the window at the world outside. He didn't hear Karyn's mom tell her that her and Karyn's we're heading away for a few days, leaving Karyn and Jon at home alone.
Karyn felt relief and Job would have felt the same to learn that they could spend a few days without anyone else around, hoping they could revert their old personalities for the majority of the time. Karyn looked back at Jon and noticed he wasn't paying attention. She figured his proximity to her mom was probably the reason and seeing him sucking his thumb only reinforced that.
After they got home it wasn't long before Karyn's parents were gone and she sat down next to Jon and told him to relax and try to think and act like his old teenage self now that they were the only ones home. Jon really tried. It took him a while but eventually he found his mind returning fully. He looked at Karyn and felt a hint of the old attraction he used to feel. Karyn asked him how he was feeling and he managed to say, "Actually Karyn, I feel pretty normal. I'm not sure I can walk any better and I'm still really weak but emotionally I feel like my old self again. And I feel.... I dunno.... Normal again." As he said that he looked down at the little dress that barely covered his diaper. He pulled the dress back and the swollen erection in his diaper was obvious to Karyn. Karyn blushed when she saw it but then smiled at Jon. "It's nice to have you back Jon, even if it is temporary." Karyn reached out and hugged Jon, giving him a squeeze which caused him to whimper. He told her to be careful, that he wasn't as strong as before. Karyn apologised and hugged him more carefully. Jon feeling a bit cheeky reached up and touched Karyn's boobs. He had been getting lots of time with her breasts all day but this felt different. He wasn't only concerned with drinking from them, instead he played with her nipples and gently squeezed and caressed them. This caused Karyn to exhale sharply and close her eyes.
Jon put his mouth on her nipple and started to play with it using his tongue. At this point his newly developed habits seemed to kick back in a little bit and he couldn't help but suckle on her nipples while moaning in a mix of contentment and sexual pleasure. The milk that came into his mouth only encouraged him more and he squeezed one breast while feeding from the other. Karyn was in heaven and she proceeded to gently rub the front of Jon's diaper which caused him to start grinding his diapered erection against her hand. After a few minutes of this Karyn felt Jon tense up and he came right in his diaper. He moaned in pleasure and Karyn felt herself climax at the same time. She had never climaxed from breast play before but it felt amazing. They both enjoyed the afterglow and Jon lay in Karyn's lap staring up into her eyes. After several minutes of silence he wanted to say something romantic to Karyn but when he opened his mouth all that came out was some baby babble. He tried several times to use real words but his babbling only became more jumbled which caused Karyn to laugh lovingly at him. He started to laugh too and this relaxed him even more which released his bladder, fully soaking his diaper now. This would have humiliated Jon in the past but he didn't care anymore.
