"I want you to cum in my belly button."

He always fills up my pussy or my throat. So I wanted to try something a little different. Of course, I start on my knees, sucking and gagging and licking his dick. I want him to be as hard as possible, as eager and full of cum as possible when he loads up my belly button. Then, we both masturbate- me with a vibrator, jiggling my fat belly to entice him. And that's when I get what I asked for.
