A pretty damn dark caption.
"Oh my god." He said, his stomach turning as he stood in the doorway, looking into the room. There was his wife's body, sitting there in the chair where she had been when he left so they could do the procedure on her, but now, it wasn't her. Above her neck, smiling at him, was the head of an old man. He saw the stitches where part of his neck and his wife's neck were joined.
The old man smiled at him, and then let out an amused laugh.
"Oh, you do look quite the sight! So shocked, so horrified by me!"
He stood up, smoothed out his dress, taking a moment longer near the breasts and then put those soft, feminine hands on her hips.
"I can see why you were so attracted to her, you know. I'll bet you two had a great time in the sack."
The old man walked slowly, strutting a feminine strut, those long legs looking beautiful as he got closer and closer to her husband. Within a moment he was right beside the man and smiled, putting his arms softly around her husband's neck in a careful embrace, all the while with a terrifying smile.
"Well, since she's no longer around to take care of that for you, I think I could step in. Don't mind the old head or that her head is gone forever. The age just means I'm very experienced in knowing what a man likes. It's not like your cheating. Hell, even the ring is still on her finger! What do you say?"
