Giving my husband the best orgasm!

My husband and I have always had great sex but over the years it's just become the same thing time after time, so we like to switch things up now and then. Sometimes it's strictly "foreplay" other times he masturbates to me. Now my husband has always liked his "boys" played with; he even begs for it when I'm going down on him. One night when I was giving his "boys" some attention I told him I wanted to try something new. Since we are both open to new things he didn't really question me. I told him I wanted to try to get him to cum almost strictly by sucking them. Ladies, let me tell you; I have never seen my husband that hard before! And the best part was he wasn't begging for attention of his dick; he was so much entangled with what I was doing; that it wasn't even a thought in his mind. This went on for 45 minutes, yes 45 minutes. Finally I wet the tip of his head, rubbed it ever so slightly while deep thoarting his balls. Ladies, I've never seen my husband orgasm so hard before, it was the most amazing and most intimate moment.
