Pretty hot young russian sc.rwing behind my back. I'm 61, shes 24?

Im a 61yr old male. i left my wife 5 months ago, i figured i have only a few years left and i wanted to live them happily. My wifes 56 and basically hadnt got my drive...i'm still like a rabbit, she had not interest in that side of things. I was lucky enough to have retired on a very healthy sum of money and have property all over the city. I moved myself into a penthouse. I hired a hot russian 24yr old to do my cleaning. I hired her on looks. To cut a long story short, she made it obvious she fancied me. We are now an item and the lady is a stunner. Shes able to match my drive and she has enormous 32G bosoms. They are natural, not plastic. However, i'm feeling real jealous as she tends to flaunt herself with younger men and my mate saw her down in a bar with another mans hand on her backside. He said he wuold be pretty certain the other man could be having a go on her...what shoudl i do? Tonight i'm getting ready to go to that club where her and her friends hang out. I figure if shes got a man there she wont want me to come. I'm constantly giving her money as i want her to have a good time, but not with other men?
