Nina and Daniella have some things in common but are very different. Daniella is more of a girlfriend. She's chatty and friendly, and she wants to get to know you, wants to know what you like, and the better she knows you, the better your sessions become. More girl next door look, compared to Nina, who is much more exotic with her mixed race (French, Chinese, Jamaican).
Nina's just going to ravish you. Your body will be tender the next day.
