This, to me, is an extraordinary piece of work and I nearly missed it because of the warning about graphic language. No criticism, I'm just inclined to avoid what is often the tedious over-use of some common expletives as a badge of 'authenticity'. Nevertheless, some words do make me squirm even though I can also see that offence arises simply because social convention says it should. We live in a world where sex and violence are standard TV fare (cf CSI) but the particular arrangement of a few letters gives some of us apoplexy.
I'm glad I wasn't put off. To me, this was not pornographic although with a different voice it very easily could be and if it were a film, how it came across would depend on what the director thought it was about. To me, neither the content nor the language were gratuitous, put there to shock me, or lacking in any purpose other than to capitalise on titillating exploitation. I don't know who was the victim here; the woman, the alien, or maybe both. There is no guarantee that the bipedal creature appearing at the end was a saviour to either of them and so no ultimate salvation. She may have been climbing to her death or to further exploitation, who knows?
What I do know is that the sense of dissolution of personality, reason, hope, and time created by the endless sexual encounters of each insular and solitary individual gave insight into the lengths human cognition will go to maintain its sense of self and to rationalise its actions. I don't know if the alien was experiencing something siliar but it felt pain and it locked the woman out after something inside it broke. I don't need to know what that was, I was happy to conceptualise it as a part of its spirit, its own survival repertoire, a valuable something that had to be protected.
The story didn't end but then some don't. It didn't leave me hanging either because I could occupy my thoughts with the uncertainties. Where was she going? Was she rescued? Or was the alien being rescued from her? Or were both about to be subject to further de-personalising experiences? In the end, the sexual content and the language seemed to be just vehicles for the expression of attempts at survival in the context of desolation, depersonalisation and loss.
