Help finding author's works

[sarhjinian]

I'm looking for a particular author; I'd thought I had his/her works bookmarked but must have lost them.

The only story I can describe was, I think, an erotic couplings entry between a younger, scornful and vaguely punk-ish girl and a thirtysomething man who meet in a convenience store, walk home together unintentionally and find out they live in the same building.

Most of the search terms I used in Google don't seem specific enough and/or the details I recall must appear on different pages.

I understand there are probably many, many requests like this. I appreciate any help anyone can give.
