Hotch/Reid, kidnapped

I read a story a longgg time ago I think on Livejournal where both Reid and Hotch are kidnapped. I think their kidnapped by a previous unsub's mother and this was her revenge for capturing her son (I could be wrong about this bit though). Anyway they are taken to this place that is completely isolated and probably underground. It has everything they could possibly need and they're forced to live there with no way out. I remember them finding condoms and I'm pretty sure there being only one bed and realizing she expects them to develop a sexual relationship (which they do). Eventually they're found by the team and I remember when they're being rescued Morgan or someone notices the used condom in the trash but doesn't say anything.

Tags may not be completely accurate, did them according vague memories about fic.

Thanks to anyone who can help!
