The first bit of conversation, it's unclear who's doing the talking. Is she using archaic language? I'm not sure. Other than that, I always enjoy the imagery you use, and the twist endings are fun. I think that you could develop this story with more intro and outro, so to speak, if you wanted, but I suppose that's the point; this was supposed to just be sex, right?
Oh yeah, and I'm pretty sure Goddammit is one word.
