Have my wife’s sister who gives me seductive looks and such. It’s been doing now for years but I never acted on it. We always exchange eye glances and there’s been moments where she does things not so normal. For instance yesterday was a family dinner and she was kneeling over looking for a item in the cupboard then when I entered the kitchen she got on all fours doggystyle position and I had to look and other times were she left explicit photos on her phone for me to see deliberately. What should I do...I’m curious to know if she wants something sexually or what’s the deal here.
