Your faithful girlfriend betrays me by cheating! Caught off guard

This raw homemade video catches my friend’s unfaithful wife caught red-handed as they’re engaged in an affair right under our noses, literally. It happens when we’re having dinner together; she takes one look around before grabbing hold of another man who is lurking through the window pane just outside their bedroom. As soon as she notices his presence too late but still manages to keep up appearances for now. My best mate then leaves abruptly after seeing what happened so there’s only confusion left among them afterward since none expected such betrayal coming out like this unexpectedly during family time.
