Rewarded by passion -- or marriage?

What did handsome Italian businessman Lorenzo Forli mean when he said that Jess would be his "reward"?

When Lorenzo proposed, Jess thought she understood: to make her his wife was what he ultimately wanted. Now she had no qualms about letting her husband-to-be make passionate love to her. But there was a shock in store! Lorenzo had failed to tell Jess something about his past. Could it be that he'd used all the means he possessed to claim the reward he'd really wanted -- to seduce Jess into his bed?
