Written for this prompt on the Avengers kink meme: "The more he thinks about it, the more Bruce feels guilty about that whole trying to kill Nat on the helicarrier thing. The fact that he's attracted to her doesn't help, and he dodges her, burying himself in his work. Meanwhile, Natasha's been meaning to talk to him and make it clear that she's not scared of the other guy anymore, that there are no hard feelings over the incident...The UST is especially difficult because he thinks in general it'll get ugly if he tries to have sex at all, but Nat thinks otherwise, and maybe the best approach is for her to take the lead and let him relax and enjoy it."
Thanks to the OP for the lovely prompt, and for continued support while I posted it in not-very-forthcoming chunks. Both were much appreciated!
