A complete rewrite, taking to heart your advice to make it dirtier and to portray how much she loves it.
Fugue State (Version 4)
I sucked gleefully on Michael's cock as he rammed it to the back of my throat, his hands guiding my head along his length. His wife Michelle pierced my cunt with a strap-on and grasped my wrists, keeping me on my knees, exposed to their assaults.
As the duo ravished me, a sense of dread overcame by body, as if I was forgetting something of life-or-death importance. Within moments feeling dissipated, and I once again succumbed to the pleasure.
The couple handled me like a filthy piece of meat and I loved them for it. I licked the penetrating cock and thrust my hips in rhythm, feeling more satisfied and full than in my entire life.
Michael's cock erupted in my mouth and that feeling returned, but this time, it blossomed. It was at that moment I realized my tragedy.
Memories of my husband and children returned in a flash- memories of my spontaneous desertion.
I let loose a muffled scream and my lovers loosened their grip. I crumbled onto the bed and Mike's cum blasted across my face.
I cried in a pool of cum as I accepted my horrible mistake.
