Dude,in my mind she is "CHEATING" not cuckolding.......I would check her on that ...let her know you know what's up....
If she wants to just fuck behind your back...and refuses to share the details of her this dude activities ....I don't understand the idea of being all shady and secretive ...when you want her to fuck other people......
Fucking behind your back is just wrong to me... there is a huge difference in hotwife/cuckold and cheating .....
I mean I like when my wife fucks others...as long as I'm included ..either by being present to watch/listen/join....or know about the meeting BEFOREHAND and and getting ALL the details when she returns....If I cannot be present pics/video would be nice..but hearing the details of how things went,,,anything to make me FEEL included ...ya know. just my thoughts
