The long tube pushes in further, but stops as soon as the female creature feels a barrier inside, and continues sucking even more as the diver's orgasm wracks her body.  Savoring the taste of the human as well as the blissful feelings inside her mind, the guardian creature is soon satisfied as well, though she wishes that she wasn't the first, and a male had taken the human before.  Savoring the virgin climax, the alpha female leaves the woman's maidenhead intact for the male in the next chamber.  After all, that's how they reproduce. As soon as the pleasure fades and the fear is renewed, she releases the diver from all of her tentacles, but stays where she is.
