groomer
Example:
"At the age of 16, an attractive, naïve, yet horribly precocious only child living in Twickenham, Barber began a two-year sexual relationship with a much older man whom she calls Simon. Nowadays, flashy Simon, with his posh motors and fancy cigars, would be called a predator or a groomer but back then, still in the days when even the brightest girls were expected to bag a man at the first opportunity, it was Barber's parents who actively encouraged the affair."
