i second that! This is exactly the sort of BDSM i can get in fic. Every other bdsm seems to gloss over the parts of a romance i like the most, the angsty can i trust him enough phase, but even in normal relationships it takes time before you know for sure what your partner's limits are. this is the only bdsm breakup-(possible)makeup story i've read, and therefore you have to finish it, for the posterity of all sga bdsm fics!!! and also i have to know if john and rodney are going to make it or if john went too far... ( i don't need back story, the prev fic was good enough for me.)
