BDSM where someone *uses* their safeword

[mecurtin.livejournal.com]

Someone in another fandom was looking for BDSM stories where the sub actually uses their safeword during play, and the Dom respects it. I could think of only two in SGA:

The Spaces Inside, by lavvyan

Something New, by cjandre

Interestingly, both are sub!Rodney stories -- possibly because it's part of his character that he doesn't trust people, or the universe, not to physically harm him.

Anyway, can you-all think of any others?
