Story #1: Tony's suit fills with water during a mission. Cue in flashbacks to waterboarding and torture while he was kidnapped in Afghanistan. Steve starts to notice something's wrong, and Pepper and/or Natasha (who know Tony's file) try to subtly explain what happened. Steve starts to spend time down in Tony's lab to keep him company, drawing and whatnot. I specifically remember Tony having a hard time while showering because of the PTSD.
Story #2: Tony and Steve are at a party. Tony gets drunk and seduces Steve. I remember that it was pretty explicit with the face-fucking. Tony manages to sneak out before Steve wakes up, and proceeds to avoid him for a long time. Turns out that Tony has been in love with Steve, but doesn't think Steve feels the same way (Steve might have been drunk during the party, idk). Steve eventually manages to track Tony down and confront him about what happened. Sex ensues.
I would appreciate any help I can get with finding these fics! Let me know if the summary's are too vague, and I'll do my best to explain certain scenes that I remember. Thank you!
