I can’t quite place my finger on it, but I think it was the “Do you want to see my owls? I keep them in the basement” line where things went from amusing to borderline-creepy. Which I’m kinda assuming was the point, so good job. :) (Although, I gotta admit, I am kind of curious as to what the “owls” actually were, if they weren’t owls)
He seems really demanding at first, with the shoes line, and it gave the whole story a feeling of her being a prostitute to me. Which may be intentional, but the rest of the story didn’t seem to imply anything of that sort. I did like it quite a bit other than that, it just threw me off for that one short bit.
I really liked this, especially how little the sex features. Excellently paced, and technically almost perfect. Very nice work with the dialogue rhythm as well, commas as pauses can get very tricky and you handled them elegantly.
The one technical quibble I have is using “slipped” twice in the same sentence towards the end.
