(A complete rewrite, save for some similarities in the last few sentences. I tried to play up the dirtiness, and the contrast between her life as reverend and her life in a menage a trois. I agree with your advice that the filthy language works well.)
Fugue State (Version 2.0)
By Razor7826
The world around me shatters and whirls back into focus. Everything is new, and my senses readjust. Salt on my tongue. Sweat in my nose. Blur in my eyes. Slapping in my ears. I feel full, a wonderful warmth touching my soul like never before.
I realize my predicament. A cock in my mouth. Another in my pussy. I'm meat being bounced around for pleasure. I start to scream, and the filth in my mouth begins to rumble and erupt. They pull out, but the cock blasts warm cum over my face as I fall sideways onto the bed. My body feels sticky. This is not the first time I've been defiled.
A bearded man leans down and shakes me. "Rachel! Rachel, what's wrong?"
The Asian woman from behind screams in panic and drops her dildo. "Rayche, oh my god, are you okay?" She starts to cry, and they both hug me like a perfect little family. I recognize neither of them.
Four years gone. They call it a fugue state. Drop your life without realizing and start anew, a completely new person in the same living shell.
My name is not Rachel. It's Reverend Rebecca Kent. For the rest of my life, I must hide from my parish the disgusting sins I committed as that other woman.
I love my husband and daughters, but as each day passes, I long more and more for the gentle touches and filthy acts of life with Mike and Michelle Lee.
