She decided to go for broke.
"Jon, I really am jealous, your breasts are great the size they are, and look great on your frame, not like my huge melons."
"Thanks Karyn, I know they fit my body perfectly. I just wish we could have done something to fix your breasts. If I could, I would give you mine and take yours, but right now we cannot do that because it would be undoing your original wish, which is a no-no. Hey, Karyn I would love to chat some more, but I really need to hit the sack, can I talk to you tomorrow, thanks night."
Jon needed to get to bed and fast. Knowing how much time it takes Julie to look as she does, he would need to get up extra early so that he had a chance to shower and wash his hair. It is times like this he regretted letting his hair get this long, but the breasts were a lot of fun in the shower. However, he needs to remember to focus, because if he gets distracted, he might end up wearing her clothes in the shower, and that will not be cool.
