Even more Ironman

So, I was recently complaining to someone about the dearth of actual sex in all the Tony/Pepper fic I'd been reading. A big exception to that is svilleficrecs's stuff, especially the newly posted story Irreparable, which has tons of sex, albeit of the deeply fucked up kind. Pepper sees something she shouldn't; Tony reacts and things get out of control; then after Pepper gets kidnapped their relationship gets even more seriously messed up. Parts of this story are quite dark (I would heed the warnings at the beginning), but it's wonderfully done: psychologically complex, fascinating, hot and disturbing--yet with a believable happy ending.
