Great post such a turn on. Maybe next time you have another guy in your mouth as hubby is on top of you, tell hubby to suck the guy a bit for you to see and maybe ever have the guy cum in hubby’s mouth?
You are doing good with what you have started. Maybe wait a few days then ask her if she gave what you suggested any more thoughts and ask her what her feelings are about the whole thing. Don’t bring up who just what she could do.
Maybe ask if she want to watch some porn about wife sharing
