Coiled

[Philatone]

hello aish! some things I thought, though they should be taken with a big grain of salt...

..to a degree, I am with the others on the formatting. If it captures "coiling", then why not do more of it? I'm imaging a shape that goes more in and out than what I saw; playing with line breaks could make it more consistent and even, but I'm hesitant to disrupt the lines you purposely crafted

In the twilight of a sibilant heart
spinning mouths ... if this is talking about spiders, then I do agree with Erthona, seemed a bit of a stretch to link the mouths to the biology of a spider. i'm not 100% convinced yet it is; the more I read, in fact, the farther I go from that conclusion--heading towards something closer to mark's view on it discussing relationships
embroider silk embraces... originally, I saw coccoons here, hugging what's inside. now, i'm leaning more towards a sense of delicateness
from the sky of impersonated longing. ..this line lost me
Eggshell gestures "eggshell"'s describing the "gestures" as fragile?
barter cankered covenants..this line, if discussing relationships, is fantastic
and the snarling flint of skin.."snarling" is powerful; gives this line some teeth
grinds against the whetstone of lustful danger. ..I'm seeing a desire for an escape, whether of people or emotion; agree that this line may be the poem's treasure
When pain becomes a broken hunger
who is the lover, and who is the knife?

..interesting close, giving each person the same characteristics. i have nothing to say on it

need some more reads of it; the "impersonated longing" line still is beyond me. do feel I'm getting closer to an understanding, though how far I've gone from your intentions i'm not sure at the moment...
