Without my friend seeing us! - Big-bottomed MILF pays more attention to her husband than her best friend

I go to visit my best friend's house and I can't help but notice her husband, who is so sexy and muscular. He starts flirting with me and, without my friend noticing, we start having fun in the kitchen. She leaves for a moment and we take advantage of the opportunity to enjoy a good fuck. But guess what? She comes back and catches us.
