I do it a lot
Usually I sit on my wife's tummy and fuck her titties and then finish by jacking off on her tits. She loves watching me jerk off.
I tell her I know my friends would love to shoot a load on her titties and this always makes me cum. I make her wear low-cut tops and go braless whenever one of them comes over. I have her bend over in front of them too. She told me one time she doubts they are interested. I just said "well, you're wrong, I know they would love to shoot off on your beautiful titties".
I also tell her I like remembering the story about the first time she sucked cock. It was her best friend's brother and two of his friends. She sucked all three of them the same night when she was only thirteen years old
