By her own admission, when "asked" to, she walked over to the bed of her own volition, and laid down (no mention of who removed her clothes, though). That is consent enough to avoid a rape charge. All she had to do was sit down, continue to say no, and wait for the door to be opened, or for them to mover her physically to the bed... THEN it's rape. She basically wanted to get it over with, and complied. Not the most romantic scenario... but not legally rape, either.
(Heck, if the female "jeez louise, let's get it over with" impulse is tantamount to rape, then most marriages feature rape on a regular basis.)
Once the woman has said no, the exit way was blocked, the door was locked and the threat of force of violence was issued, it is rape.
