I will invent a term. Secretary Plus. There are indeed Strings Attached. Since 2 people are friends and have from time to sex. Here, Jacob, the head of a packaging company a secretary Plus. Because that is so attractive and horny that he does not succeed, you only transfer works, but he wants her body, your pussy and fucks her from time to time right through. But they like to blow his cock. So maybe my term is secretary by Plus.
