babies in my belly button

Me and my boyfriend were having sex and usually during sex him cums on me. This time he was on top tearing me up like always 😍, he pulled out and i grabbed his dick giving him a hand job so that i can get all the cum out before putting it back in me. He then gets up to get a towel and does like a double take but he's looking at me but im like yeah you came on me. then he looks closer so im like oh no, lol it was his load of cum in my belly button lol we just both laughed while he wiped a pool of kids out of my belly button. few mins later there was a pool on my back and then another on his self.
