Unaware wife

My wife is one of those women that wears yoga pants everyday even if she is not going to the gym. The yoga pants that she wears tend to be skin tight and show every curve of her ass and legs. When I am with her in the grocery store I frequently see men staring and if I leave her alone they will stay in the aisle and look again and again at her tight round ass. I even once saw a guy pull out his phone and start taking photos of her ass. She has no idea that every guy that sees her thinks about using her body. Sometimes I just wish they would take another step and grope her.
