Bucky: Don't get me wrong, I'm glad you're healthy as a horse now, but. Do you have any idea how cute you were, how easy it was to carry you everywhere, how utterly huggable your body was?
Steve: W-well, sure, I admit this body'll take some getting used to, but think about it! Now I can be the one carrying you! wouldn't that be a nice change of pace?
Bucky: No, Steve. No it wouldn't
Basically that uncomfortable moment when you realize your boyfriend is secretly a borderline shotacon ಠ_ಠ
One of the things I like most about Stucky is the fact that Bucky is (as far as MCU goes) the only one who loved Steve before the serum and becoming Cap. That just. gets my heart strings a-pullin'.
Course I like to pervert this by thinking Bucky is also genuinely attracted to skinny!Steve and all the power he has over him but shhh Here's a NSFW Stucky fic that's somewhat tangentially related btw it's p good try giving it a read sometime
Steve + Bucky (c) Marvel
