When a woman who has more than one guy on the go and wants a baby decides to 'let nature decide'. Often lets the guy with more cash think it's his when she gets up the duff.
Being white and blue eyed I didn't need a DNA to know the baby wasn't mine. Turned out my now ex was broody and seeing my black mate on the sly and decided to have a spunk race.
