The landlady is about 40 years old and her husband is often away from home. Sometimes she plays some dirty jokes in front of my wife and me. What does this mean? Can I fuck her?

It may just be casual, so be careful. I suggest that when your wife is away, I use this reason to ask her to come to your house and dress sexy, you know, and see how she reacts. If you avoid it, it means there is no chance. If you stay, it means there is still a chance. I can only help here. Hope to adopt!
