Flash Fiction / He keeps her in the shed

a dog!
i had a feeling it wasn’t as gruesome as it initially sounded.
this is a good concept.

maybe you could develop the build up a little more.  suspenseful diction, longer drawn out sentences.  words like “strolled” and “approached” don’t give the effect that something is lurking beyond the shed doors.

the more intense the buildup is, the more surprising the ending is.

You get high marks for keeping it short and unexpected at the end.  The title does a great job of setting up the readers expectation that this will be about a woman which adds to the shock value in the end.

I had trouble with the flow because the sentence structure was sloppy in places:
“He strolled to the yard towards the shed he put her in the night before.”
He strolled to the yard from where? or did you mean :

‘he strolled across the yard towards the shed where he put her the night before.’

“As he approached, his footfalls alerted her and muffled cries could be heard from inside.’
’...she was alerted by his footfalls and her muffled cries could be heard from inside.’
Just two examples to show that some editing might be needed to improve the movement through the piece.

Man. Love this. I very much like the bdsm-esque language. The only problem I have is that the title is a little too telling, right away I assumed it was a dog (considering this is flash-fiction, as well). I would change the title. The language itself could also use work, it’s very good but with a bit more attention I think it could be even better. Especially as far as descriptions and, perhaps, the feelings of the characters (specifically the man’s).
