AIO - Wife has sex with neighbor in front of entire family

Hey guys - so my (M, 25) wife (F, 67) has recently been bringing my neighbor over to our house in the evenings to have sex with him in front of me, my two stepsons (M, 30 & 34), and our family dog (Rufus, M, 3).

We have all told her that it hurts our feelings when she does this. I’ve already forgiven her for cheating on me at least two dozen times I can count on in the 10 years we have been together. Whenever we confront her, she accuses us of being “overly alpha” and says that we are “slut shaming” her.

She also had diarrhea the other night and purposely went into my man cave and defecated all over my original Furby collection. She didn’t really provide a reason for that one.

AIO over to this? Should I leave my wife or am I being a “spineless little cunty-bitch” like she says? Any advice is appreciated.
