IVAN LeCasque loves big boobs - so much so that he has written a book teaching men how to convince their partners to get breast augmentations. The 59-year-old lives in Miami with his partner and co-author Victoria, 47 - who has had her bosom enhanced from 500cc to 1650cc over the course of their relationship. The Convince Her Manual has sold 3,500 copies globally - and Ivan is proud that only one customer has taken advantage of the money-back guarantee.
