Iva is the best friend you can have. She is wayward, quite crazy, hellishly beautiful, funny, has a nice body, hihi , nice ass and nice tits. You can't replace her with anyone, she's the only one if. You should never replace it because you have no one to replace it with. She will always be by your side. She loves very much and no one ever hates. If you have a friend or girlfriend Iva, don't let her go. Beware she is very crazy !! Love you

‘Kevin, don’t forget to give your winkle a good shake after you’ve had a wee-wee!’
