(Marvel MCU) Stuckony
Help me find a fanfiction, here is what I remember:
An ABO AU where bucky is just a normal soldier at war and he comes back to find that Steve has selected omega tony and they are together where as in reaity steve and bucky have been together longer. Steve is a switch and gentle Alpha that cooks and plays with becca (Tony and his PUP, named after Bucky's sister) and the society views omegas as less than alphas but alphas cant be in a relationship with each other so bucky and steve have to hide it.Despite steve having saked bucky for permission to be with Tony, Bucky is really mean to Tony and makes him make dinner, he overcooks the stakes and Bucky makes him eat salad and is impatient with Becca. Bucky is initially really mean to tony but grovels at the end and it ends stuckony.
