I'm searching for a fic where both Jim and Spock were kidnap for many years ( i think) They thought the other had been kill. Jim is use as a sex slave, control by some device trough pain and pleasure When jim find out that Spock is alive, is desire to live come back and he escape.

He find spock freezing in a cage and free him, then they try to make their why out of this place.

it was a rather long fic
