Ha! My rereading fanfic has least to me finding that one single line I’ve been trying to remember for months now. Woohoo. It was in Tea Time With Alicorn.

It gets points for the pairing, but the writing was just too unpolished for me. Plus it used the word lesbimare, which just sounds silly. Which is an accomplishment when the word it is competing with is fillyfooler, a fairly silly word itself.
I suspect this was a casualty of the ebooks stripping all formatting from stories. It was done in letter and journal format, but lack of any kind of horizontal lines or page breaks, most of them kind of ran into each other. As for the story itself, it wasn’t bad. Pacing was a little rushed, and the author doesn’t quite have the letter format down completely, but despite all that it was a pleasant read.
