Shidave - it could be either, or, more likely, both. I am sure that she'll want to see him if he isn't going to be around later this week. I don't think there's any doubt that she wants her time with him. I can see that when he's away that there's, shall we say, "less spring in her step...".
Harry - I honestly don't know if she'd want to go with Don. In light of your question, if the time is right later tonight, I'll see if I can ask her as if "what if....". I do not think she'd want to go away "on vacation" with him - I don't get the feeling that she'd want that (maybe she's cautious about her own feelings). I suspect that her own emotional state as relates to Don might push her a bit, but I don't think she'd want to go. As I said, I'll see if I can work it into our conversation - or hopefully - foreplay later tonight.
Regarding my son. About the only outgoing reason for my saying anything is that he's stopped asking about our plans for Friday nights. He may have put things together - first Thursdays and now Fridays.... I'm hoping he has the right understanding of the situation - he surely knows that Sue and I have sex as there have been several close calls (knocking on our door while she's moaning away under me, finding her underwear in weird places, no longer asking what Astroglide is, etc.). He long ago found both Penthouse and Penthouse Letters magazines so he knows we are somewhat open sexually - I don't think it'd freak him out if he knew his mom fucked other guys but he probably lacks the maturity to put it into proper context. At his age, sex is in a different place to him than it is for us.
Harry - regarding your last note - I have to agree 100%. Whether you did or did not adopt a cuckold lifestyle - the fact that you are open to have talked about it is a sign of the depth and maturity of your relationship. From there - to me, whether you do or do not - if you can talk about it, you can talk about anything. The more you communicate the better the relationship will be. I can honestly say that we are in a very good place in our relationship - in addition to being in love with each other, we are comfortable with each other.
Sue just sent me a text message just saying "hope you're ready for later".
