If you are a mature brunette and you find yourself with your man having an intercourse session and you are not sure whether he is cheating or not, you might be wondering what exactly would make him jump from behind and shoot his load all over you. There are two main factors that make a guy go crazy and they are curiosity and concern for you. So the next time your mature male partner wants to get things heated up again between the sheets, you should try and get him curious by asking him what he remembers about your first love, his reaction to your touch, how his granny was looking at you, what you were doing when you finally made it over to his place for the second time, and of course by going down on you and giving him a blowjob instead of just going down on him in the missionary position..
