YES AVENGERS ORGY YES YES YES. Oh fandom, I knew you would not fail me. I mean, you failed me with XMFC (when I had to write my own orgy), and Captain America (wheeeere were my threesomes), but I knew you wouldn't do it a third time. HOORAY TEAMSEX.
I rewatched a crappy cam of Avengers to plan bathroom breaks if I decide to go again, and I have been confirmed in 1.) my pairing choices and 2.) my initial impression that this movie is really not that great. Let us take them one at a time.
