Upturned pillow?

Originally for a challenge, last line describes all!

Dare you to trifle
with those components?
Concepts based on
Simultaneous desire,
Deplorable reasoning behind all actions.
[But we don’t mind, I swear it]
Dire consequences around
Every meandering corridor

Conceptual reasoning is flawless,
As our discussions lead to naught
But sly glances and parted mouths
[Lips, hips, and legs, you fool!]
Nothing contrives ideas like
Every instinct that is idealized
In an upturned pillow
