Trying to find these books

Okay ladies and guys,

I am trying to remember a series of books the first book that I can remember is about these two vampires that kidnap a woman at an airport. They do this because one of them is in this mating heat/ feeding cycle time or something like that. Anyways, the girl is part of a bigger picture. He mom joins a cult and had stolen a package from her daughter and the vampires were looking for it. Anyways these vampires are Bisexual and they keep this woman for I think two weeks. Everybody has lots of sex and a HEA.

I think this is a totally different series but this guy kidnaps this woman in her bookstore (I think) marries her in the parking lot and takes her to his home or castle. He is in to the Bondage submission thing also.  She has the option of divorcing him but it leaves him with less power. After numerous attempts at killing her and him he makes her leave and she goes. But did I forget to mention he is a vampire or the King of the vampires. I really liked these books but I read them about a year ago. I think they were ebooks and were prolly lost on the old computer. I want to get those again but I didn’t have a print out of what I had bought when. Anybody have any ideas?
