It was Tony/Loki or eventually became Tony/Loki. For some reason Loki, Tony, and I think Thor and Steve had been captured and they put Tony and Loki in the same cell. They realized they were being watched and I think the captors expected Tony and Loki to attack each other. So somehow they come up with a plan to fake a rape between Loki and Tony(with Loki being the 'attacker'). They actually are just having really rough but still consensual sex but they are so convincing the Thor thinks Loki actually raped Tony and Tony I think was unconscious or just really injured when they were rescued/escaped and couldn't explain what really happened before Thor attacked Loki.
That story was part one, I know there was at least three stories in the series and the second part happened on Asgard and both Thor and Tony get uber protective of Loki when Odin goes to far punishing Loki for the perceived rape. In the second part we also learn that Loki was tortured by the Chitauri and they might come back to Midgard for revenge against him which I think was the theme of the third fic which I didn't read. I don't know if there was more to the series but like I said it definitely had three parts.
Any other brainwashed/controlled Loki fics would be great but not necessary.
The main general fic I'm looking for is any of the Avengers or any of the extended family getting injured or sick but the focus on the fic being on the Avengers, or others, taking care of them in their convalescence. Like making sure they take meds, changing dressings, basically acting as Nurses or even 'Mother Hens' to the sick/injured person. It can be fluffy or angsty but happy endings preferred.
Thank you and happy readings to y'all!
